However, it?s important to consider that constant fast charging can generate more heat, and heat is one of the factors that can accelerate the degradation of Li-Po batteries in the long term. Managing charging habits will be key to preserving its health.

Build and Durability: Design and Resistance

This model features a design with glass on both the front (Gorilla Glass 5) and back, with a plastic frame. Its dimensions are 164.2 x 76.1 x 8.1 mm, and it weighs 202 grams. It has an IP53 certification, granting it resistance to dust and water splashes.

Care Analysis: The use of glass on both sides gives it a premium look but also makes it more susceptible to damage from drops compared to materials like plastic or metal. The plastic frame can help absorb some of the impact. The IP53 certification means it?s protected against limited dust entry and vertical water splashes (like light rain), but it is by no means submersible. Avoid direct and prolonged exposure to liquids, as water damage can lead to serious failures, including motherboard issues.

Connectivity and Other Details

The Redmi Note 11 Pro 5G is well-equipped in connectivity, offering 5G, Wi-Fi 802.11 a/b/g/n/ac, Bluetooth 5.1, NFC (availability may depend on market/region), an infrared port (IR Blaster), a 3.5mm headphone jack, and a USB Type-C 2.0 port with OTG support.

However, it can also include a considerable amount of pre-installed applications (bloatware), and sometimes users may experience bugs or unexpected behaviors that affect the overall experience or battery consumption. Keeping the software updated and optimizing its settings will be important.

Table: Key Specifications of the Redmi Note 11 Pro 5G (Snapdragon Model)

The balance between premium features and points of fragility is evident. The phone offers a 120Hz AMOLED display and high-resolution cameras, but its glass construction and IP53 water resistance limitation are critical points for care. Users may be drawn to the high-end features but should be aware that these do not imply invulnerability. The IP53 resistance is only for splashes, not immersion, a crucial detail for preventing water damage, which can lead to serious motherboard failures.

Additionally, MIUI software, while offering customization, can be a source of issues like bugs or excessive battery consumption if not properly managed. The 67W fast charging is a great convenience, but the heat generated is a known factor that accelerates battery degradation in the long term if not used prudently.

Proactive Maintenance: Key Tips for Taking Care of Your Redmi Note 11 Pro 5G

Proactive maintenance is the best strategy to ensure that your Redmi Note 11 Pro 5G provides reliable service for years to come. Here we offer essential tips divided into physical protection, battery optimization, and software and storage care.

Smart Physical Protection ?? ? Better Safe Than Sorry!

Your Redmi Note 11 Pro 5G features a sleek design with glass surfaces (Gorilla Glass 5 on both the front and back), making it attractive but also vulnerable. A high-quality case is not a superfluous expense, but a smart investment! Look for one that offers robust corner protection and a slight lip that extends above the screen and camera modules. This can make the difference between a scare and an expensive repair.

The 120Hz Super AMOLED display is undoubtedly one of the device?s strong points. To keep it pristine and safe from deep scratches or minor impacts that Gorilla Glass 5 might not completely withstand, a tempered glass screen protector is highly recommended. At iLevante.com, we have options that fit perfectly and maintain touch sensitivity.

Daily careful handling is also crucial. Avoid carrying the phone in back pockets, where it could bend or get damaged if you sit on it. Don?t expose it to extreme temperatures, as both excessive heat (leaving it in the car under the sun) and intense cold can affect the battery and other components. And remember: although it has IP53 certification against dust and splashes, this means protection against "vertical water sprays," like light rain, but it is not submersible! Keep it away from large bodies of water, such as pools or bathtubs, and excessive humidity, like bathroom steam. A user might think that Gorilla Glass 5 is enough, but experience shows that screens break. Physical protection is a direct barrier against damage that can lead to costly screen repairs or internal issues.

Battery Optimization for Maximum Durability ? ? Power That Lasts!

The 5000mAh battery of your Redmi Note 11 Pro 5G is designed to provide great autonomy, but with some adjustments and good habits, you can extend its lifespan and keep it in optimal condition for longer.

Key Software Adjustments (Android and MIUI):

• Screen Brightness: The screen is one of the most energy-consuming components. Manually reduce brightness to a comfortable level or activate auto-brightness to adjust to ambient light. You?ll find it in Settings > Display > Brightness level.
• Refresh Rate: The 120Hz provides a very smooth visual experience but consumes significantly more battery than the standard 60Hz rate. Consider switching to 60Hz for daily use and activating 120Hz only when you really need it (e.g., for gaming). Go to Settings > Display > Refresh rate.
• Dark Mode: AMOLED screens like your Redmi?s save energy with dark mode because black pixels simply turn off. Activate it from Settings > Display > Dark mode.
• Always-On Display: While useful for quickly viewing notifications, this feature constantly consumes battery. If it?s not essential for you, turn it off or configure it to only show for a few seconds after a notification. This can be managed in Settings > Always-on display & Lock screen.
• Adaptive Battery: This Android feature uses machine learning to optimize the consumption of background apps, prioritizing the ones you use most. Make sure it?s activated in Settings > Battery (the exact subsection name may vary slightly in MIUI; look for options like "Background app activity control" or "Adaptive battery").
• Battery Saver: MIUI includes a powerful battery saver mode that restricts background functions, visual effects, and performance to maximize the last percentages of charge. You can set it to activate automatically at a low battery level from Settings > Battery > Battery saver.
• App Management: Periodically check which apps are consuming the most energy in Settings > Battery > Battery usage stats. Restrict background activity for apps that don?t need constant synchronization. Uninstall apps you no longer use.
• Notifications: A constant stream of notifications not only distracts but also wakes the screen and consumes energy. Manage notification permissions for each app in Settings > Notifications & Control center > App notifications.
• Wireless Connections: Turn off Wi-Fi, Bluetooth, and GPS (Location) when not actively using them. You can quickly do this from the Control Center.

Good Charging Habits:

• Avoid Extremes: To reduce battery stress, try to keep the charge level between 20% and 80-90% whenever possible. It?s not necessary to always charge it to 100% or let it completely discharge frequently.
• Overnight Charging: Although modern phones have systems to prevent overcharging, leaving the phone plugged in all night regularly can generate residual heat that, over time, affects battery health. The 67W fast charging is excellent when you need power quickly, but if you have time (e.g., overnight), consider using a lower-power charger if you have one, as it will generate less heat.
• Heat During Charging: Avoid using the phone for intensive tasks like gaming while charging. This combination generates a considerable amount of heat, harmful to the battery and other internal components.

Battery software optimizations are crucial due to the phone?s high-consumption features, such as its 120Hz screen and powerful processor. Not optimizing these aspects can lead to premature battery degradation, requiring a replacement sooner than expected.

Software and Storage in Top Shape ? ? A Nimble Brain!

Optimized software and well-managed storage are essential for smooth performance and greater device longevity.

• Software Updates: Keep your Redmi Note 11 Pro 5G updated with the latest versions of MIUI and security patches released by Xiaomi. These updates often include performance optimizations, bug fixes, and new features. However, be cautious: although rare, sometimes an update can introduce new bugs or, as anecdotally reported in some Xiaomi cases, worsen latent hardware faults. If an update isn?t critical (like an urgent security patch), it may be wise to wait a few days and check other users? opinions in forums before installing it.
• Storage Management: Nearly full internal storage can significantly slow down the phone. Take advantage of the microSDXC slot to store photos, videos, and other large files. Periodically review and delete unnecessary files, app caches (from Settings > Apps > Manage apps > > Clear data > Clear cache), and old downloads.
• Beware of "Debloating": Some users opt to remove pre-installed apps (bloatware) to free up space and resources. While this can be beneficial, it should be done cautiously, as removing essential system apps could cause instability. One user mentioned having "debloated everything" in an attempt to improve the performance of a Note 11, but it?s an advanced measure requiring knowledge.

Heat is a recurring enemy of electronics. It arises from fast charging, intensive use, and can exacerbate battery and even screen issues. Therefore, the advice on avoiding intensive use during charging or exposure to high temperatures is crucial.

Extend Its Operation: Common Spare Parts and Repairs for Your Redmi Note 11 Pro 5G

Even with the most meticulous care, natural wear and tear or an accident can make a part of your Redmi Note 11 Pro 5G need replacement. But don?t worry!

At iLevante.com, we strive to offer spare parts that maintain the original experience.
• Brief Replacement Guide:
  1. Required Tools: A mobile repair kit (including small precision Phillips screwdrivers, plastic picks, a suction cup, and plastic or thin metal spatulas). You?ll also need a heat gun or hairdryer to soften the adhesive on the back cover and possibly the screen.
  2. General Process:
     • Turn off the phone and remove the SIM tray.
     • Heat the edges of the back cover to soften the adhesive. Use a suction cup to slightly lift an edge and insert a plastic pick to cut the adhesive around the perimeter. Be careful with internal flexible cables.
     • Once the back cover is open, disconnect the battery?s flexible cable. This step is crucial to avoid short circuits.
     • Disconnect the flexible cables (flex) of the old screen that connect to the motherboard. There may be other components attached to the screen or frame that need to be transferred (like the earpiece, sensors) if the replacement doesn?t include them.
     • Remove the damaged screen. If it?s a screen without a frame, more heat and care may be required to separate it from the original frame. If it?s with a frame, the process involves transferring the motherboard, battery, and other components to the new frame with a screen.
     • Install the new screen, carefully reconnect all flexible cables, ensuring they are properly seated in their connectors.
     • Connect the battery, temporarily close the phone, and turn it on to test the new screen and touch before sealing it permanently.
     • If everything works, apply new adhesive (if necessary) and seal the back cover.
     (Inspired by videos and general repair processes).
  3. Precaution: This is a medium to high difficulty repair. If you have no prior experience, consider seeking professional technical service. Flexible cables are very delicate and can be easily damaged. Work in a clean and well-lit area.

Battery (Li-Po 5000mAh, model BN5E)

• Failure Symptoms: The battery discharges excessively fast, the phone shuts down unexpectedly despite showing remaining charge, it heats up abnormally during charging or use, or in more severe cases, the battery physically swells (this can cause the back cover to bulge or detach from the edges). A swollen battery is a safety risk and must be replaced immediately!
• Spare Parts at iLevante.com: Look for "Original Battery Redmi Note 11 Pro 5G BN5E" or "Xiaomi BN5E Battery." It?s essential to use quality spare parts to ensure safety and performance.
• Brief Replacement Guide:
  1. General Process: Accessing the battery is similar to the screen: you need to remove the back cover. Once inside, locate the battery and disconnect its flexible cable from the motherboard. Batteries are usually firmly adhered to the phone?s chassis with strong adhesive strips. To remove it, it may be necessary to apply a small amount of isopropyl alcohol around the edges to soften the adhesive and then use a wide, flat plastic lever to gradually and carefully lift it, avoiding puncturing or excessively bending it. Place the new battery (make sure it has new adhesive strips or apply suitable ones), connect it, and close the phone. (Inspired by videos and tips).
  2. CRITICAL Warning: Lithium-ion batteries are dangerous if punctured, crushed, or damaged, as they can catch fire or explode. Never use sharp metal tools to pry directly on the battery body.

  1. General Process: After removing the back cover and disconnecting the battery, locate the bottom board, which is usually protected by a plastic cover secured with screws. Remove this cover. Disconnect the flexible cables that connect this bottom board to the main motherboard and the antenna cable. Remove the screws holding the charging port board to the chassis and replace it with the new one. Reconnect everything in reverse order and close the phone. (Inspired by videos such as ).

Glass Back Cover

• When to Replace: If the original cover is broken, cracked (compromising aesthetics and protection against dust/moisture), or if the original adhesives have lost their effectiveness and the cover is peeling off.
• Spare Parts on iLevante.com: Search for "Glass Back Cover Redmi Note 11 Pro 5G" or "Rear Housing Xiaomi Redmi Note 11 Pro 5G". Make sure to choose the correct color for your device.
• Brief Replacement Guide: Gently heat the edges of the old cover to soften the adhesive. Use a suction cup to create a small opening and then insert plastic picks to cut the adhesive around the entire perimeter, separating the cover from the frame. Thoroughly clean any residue of old adhesive from the phone's frame. The new back cover usually comes with pre-applied adhesive; if not, you will need to apply suitable adhesive for phone frames (such as B7000, mentioned in , or specific double-sided adhesive strips). Place the new cover, carefully aligning it, and press firmly for a while (you can use clamps or elastic bands carefully to maintain pressure while the adhesive cures, as seen in ).

Camera Modules (Main, Wide Angle, Macro, Front)

• Failure Symptoms: Consistently blurry photos or photos with spots that do not improve after cleaning the external lens, the camera app shows a black screen or an error message when trying to use a specific lens (e.g., the wide-angle works but the main does not, or vice versa), persistent "cannot connect to the camera" errors, focus problems that do not resolve (autofocus does not work or gets stuck), or if a specific lens is not detected by the system.
• Spare Parts on iLevante.com: Search for "Main Rear Camera Redmi Note 11 Pro 5G", "Wide Angle Camera Module Xiaomi Redmi Note 11 Pro 5G", or "Front Selfie Camera Redmi Note 11 Pro 5G". It is important to identify which specific module is failing.

Camera modules are usually connected to the motherboard via small pressure connectors (FPC type). Carefully disconnect the defective module and connect the new one. These components are extremely sensitive to static electricity (ESD) and dust. Work with an anti-static wrist strap and in the cleanest environment possible.

Speakers (Earpiece and Main/Multimedia)

• Failure Symptoms: During calls, nothing is heard or the sound is very low/distorted through the top earpiece. Multimedia sound (music, videos, ringtones) is low, distorted, crackling, or completely absent through the main speaker (loudspeaker), usually located at the bottom of the phone. The "Clean Speaker" function in MIUI can solve minor dust obstruction issues, but if the failure persists, it could be a hardware problem.
• Spare Parts on iLevante.com: Search for "Earpiece Speaker Redmi Note 11 Pro 5G" or "Multimedia Buzzer Speaker Xiaomi Redmi Note 11 Pro 5G".
• Brief Replacement Guide: Requires phone disassembly. Speakers are usually small modules connected via pressure contacts or small flexible cables. Once accessed, their replacement is relatively simple: disconnect the old one and connect/place the new one.

Other Common Spare Parts

In addition to the mentioned ones, on iLevante.com you can also find other important spare parts such as:

• Volume and Power Button Flex: If any of these physical buttons stop working or work intermittently.
• SIM/MicroSD Tray: If the original tray is lost or damaged.
• Vibration Motor: If the phone stops vibrating.
• Rear Camera Glass Lens: If only the external protective glass of the cameras is scratched or broken, but the camera modules work fine.

Although YouTube tutorials can make repairs seem simple, the reality for a novice can be more complex and risky. There is a risk of damaging other components, especially the delicate flexible cables if you do not have the experience or the right tools. The quality of the spare parts is crucial: using an LCD screen instead of AMOLED or a low-quality battery can degrade the experience or be dangerous. At iLevante.com, we focus on quality.

Table: Quick Guide to Spare Parts for Redmi Note 11 Pro 5G

Red Alert! ? Common Issues of the Redmi Note 11 Pro 5G and Their Solutions (Hardware Focus)

Although the Redmi Note 11 Pro 5G (with Snapdragon 695 processor) is a solid phone, no device is exempt from potential issues. Here we address some of the most common failures that users may encounter, focusing on hardware causes and how iLevante.com can help you with the necessary spare parts. It is crucial to remember that many problems that seem hardware-related may have software solutions or simple diagnostic steps (restart, clear cache, check permissions). It is always recommended to exhaust these avenues before considering a physical repair.

Screen Issues ? Beyond Cracks

Green/Pink Line on AMOLED Screen

• Symptom: Sudden appearance of one or more vertical lines of bright green or pink color on the screen, persisting regardless of what is displayed.
• Likely Cause (Hardware): This is a known and relatively common hardware failure in AMOLED screen technology in general, not exclusive to Xiaomi. It is often related to a defective, damaged, or partially disconnected flex cable connector of the screen due to a drop or physical stress. It can also be an internal issue of the OLED panel itself. In some cases, it has been associated with exposure to excessive heat or thermal stress. Curiously, the problem sometimes appears "after" a software update; this does not mean that the software directly causes it, but the update process (which can stress the hardware) might have been the trigger for a component that was already weak or on the verge of failure.
• Solution: Unfortunately, this problem almost always requires the complete replacement of the screen assembly. A phone restart can be attempted to rule out an extremely unlikely software error, but it rarely solves this type of hardware failure.

Screen Flickering

• Symptom: The screen flickers, either intermittently, constantly, or under certain brightness or refresh rate conditions.
• Likely Causes (Hardware/Software): It could be due to a loose or damaged flex cable of the screen, similar to what causes color lines. It may also originate from software issues or GPU driver problems, especially if the flickering manifests at specific refresh rates.
• Solution: At the software level, try changing the refresh rate (between 60Hz and 120Hz in Settings > Display) and the brightness level to see if the problem is mitigated. Ensure the operating system is up to date. If a loose internal connection is suspected and you have experience, you could check it. If the problem persists, it is likely that a screen replacement is needed.

Dead or Stuck Pixels

• Symptom: One or more points on the screen remain always black (dead pixels) or of a fixed color (stuck pixels), regardless of the displayed image.
• Likely Cause (Hardware): Generally, it is a manufacturing defect in the OLED panel.
• Solution: Dead pixels have no simple repair. For stuck pixels, sometimes software or videos designed to "exercise" pixels can work, but it is uncommon. In most cases, the only definitive solution is screen replacement.

Touch Issues (Ghost Touches, Unresponsive Areas)

• Symptom: The screen registers touches that the user did not make (ghost touches) or there are areas of the screen that do not respond to touch.
• Likely Causes (Hardware/Software): A damaged digitizer (the touch component, which is part of the screen assembly), a loose digitizer connector, or even a poor-quality, dirty, or improperly installed screen protector. In some cases, corrupt software or a conflicting app could be the cause.
• Solution: As a first step, remove any screen protector to rule it out as the cause. Clean the screen. Restart the phone. If the problem persists, it is likely a hardware failure of the screen assembly requiring replacement.

Abnormal Battery Drain ? When It Runs Out Without Reason

• Symptom: The battery drains noticeably quickly even with light or moderate use, or loses a significant percentage of charge overnight while the phone is idle and with no apparent activity.
• Likely Causes (Hardware/Software):
  • Degraded Battery: Over time and charge/discharge cycles, all lithium-ion batteries lose capacity and efficiency. This is the most common cause in phones with some years of use.
  • Software/Firmware Bug: A background process that has "stuck" or a poorly optimized app can consume resources uncontrollably. A particular case mentioned for MIUI on some models (including Note 11 and Note 10 Pro) is a bug related to the virtual proximity sensor, which can cause the earpiece speaker not to enter sleep mode properly, silently draining the battery.
  • Short-Circuit Component (Motherboard): In rarer and more severe cases, a failure in a motherboard component could be causing excessive electrical consumption.
  • Excessive Heat: Overheating the phone, whether from intensive use, charging in hot environments, or sun exposure, can cause the battery to drain faster and also accelerate its long-term degradation.
• Solution:
  • Review and apply all battery optimization measures mentioned in the "Proactive Maintenance" section.
  • Look for software updates; sometimes manufacturers release patches to fix bugs causing battery drain.
  • If you suspect the virtual proximity sensor bug mentioned in : in a completely silent room, turn the notification volume to maximum, lock the phone screen, and bring your ear close to the earpiece speaker (the top one, for calls). If you hear a faint white noise or hissing that persists for more than 5 seconds, it could be this bug. Restarting the device sometimes temporarily fixes it.
  • If the battery is clearly degraded (you can try checking its "health" if MIUI offers this option in Settings > Battery, although it is not always accurate, or based on its general behavior), the most effective solution is to replace it with a new quality one.
  • If none of the above works and the drain is severe and inexplicable, it could be a motherboard issue, requiring diagnosis by a qualified technician.

Camera Failures ? I Can't Capture the Moment!

"Cannot Connect to Camera" / Black Screen in Camera App

• Symptom: When opening the Camera app (whether MIUI stock or another), an error message appears such as "Cannot connect to camera", "Camera error", or simply the interface is displayed but the preview (what the lens sees) remains black.
• Likely Causes (Hardware/Software):
  • Loose/Damaged Connection: The camera module (or one of them, if the issue affects all) might have its flex connector partially loose from the motherboard due to a drop or vibration. Some users report that "gently tapping" the camera area sometimes temporarily reconnects loose parts, although this indicates a physical problem.
  • Defective Camera Module: The image sensor itself or the electronics associated with the module may have failed.
  • Software/Permission Conflict: Another app might be using the camera in the background and blocking access. The Camera app permissions might have been accidentally revoked. A bug in the Camera app or operating system is also a possibility.
  • Specific Module Failure Affecting All: In systems with multiple cameras, sometimes the failure of a secondary module (e.g., the ultra-wide or macro) can prevent the main camera app from functioning properly or starting.
• Solution:
  • Basic Software Steps: Restart the phone. Force stop the Camera app and then clear its cache and data (from Settings > Apps > Manage apps > Camera > Storage > Clear data).
  • Verify Permissions: Ensure the Camera app has all necessary permissions (especially Camera and Storage) in Settings > Apps > Manage apps > Camera > App permissions.
  • Safe Mode: Restart the phone in Safe Mode (the method may vary, usually by holding down the power button and then holding the "Power Off" option on screen until the Safe Mode option appears). This temporarily disables third-party apps. If the camera works in Safe Mode, a recently installed app might be the culprit.
  • CIT Mode (Engineering): On some Xiaomi phones, you can access a hardware test menu (CIT). To do this, go to Settings > About phone and tap repeatedly on "Kernel Version" until the menu opens. Here you might find individual tests for each camera (FrontCamera, BackCamera, WideCamera, MacroCamera, etc.). This can help determine if a specific module has failed.
  • Physical Solution (Advanced/Professional): If all the above fails, it is likely a hardware problem. This could involve opening the phone to check the flexible cable connections of the cameras or, more commonly, replacing the affected camera module. On iLevante.com, you will find spare parts such as "rear camera Redmi Note 11 Pro 5G" or "front camera Redmi Note 11 Pro 5G".

Focus Issues (Blurry Photos)

• Symptom: The camera has difficulty focusing, photos are consistently blurry (especially at certain distances), or the macro mode does not focus correctly on close objects.
• Likely Causes (Hardware/Software): The simplest cause is a dirty or fingerprinted external lens. It could be a failure in the autofocus (AF) mechanism of the camera module, a bug in the camera software not properly controlling the AF, or even a physically damaged or misaligned camera module.
• Solution: First, carefully clean the external lens of the camera with a microfiber cloth. Try clearing the cache and data of the Camera app. Test different focus modes (tap to focus on the screen, Pro mode if it allows manual focus). If the problem persists, especially if it started after a drop, it is likely a hardware failure of the camera module and needs replacement.

Poor Image/Video Quality

• Symptom: Photos or videos have poor overall sharpness, colors that seem incorrect or washed out, or video stabilization is poor, resulting in shaky images.
• Likely Causes (Hardware/Software): Sometimes, this is due to the inherent limitations of the hardware, especially in secondary sensors (like the ultra-wide or macro, which are often of lower quality than the main one). The image processing performed by MIUI software also plays a crucial role. specifically mentions that video stabilization on the Note 11 Pro can be poor. In some cases, the stock camera app does not fully exploit the hardware; suggests that alternative apps like GCam (ported Google Camera) can improve results, indicating that software/processing is an important factor.
• Solution: Experiment with different modes and settings of the stock camera. If you are willing to explore, look for a stable version of GCam compatible with your Redmi Note 11 Pro 5G (this may require some research on forums like XDA Developers). Ensure good lighting when taking photos/videos. However, it must be accepted that certain quality limitations may be inherent to the device's hardware.

Overheating ? My Phone is Burning! ?

• Symptom: The phone becomes excessively hot to the touch during normal use, while gaming, recording video for extended periods, or while charging.
• Likely Causes (Hardware/Software):
  • Poorly Optimized Software/Bugs: Applications consuming many resources in the background, or a version of the operating system with poor thermal management can cause overheating. While a Snapdragon 695 5G user reported that their device performed well for daily tasks, differentiating it from the G96 version, which was mentioned as prone to heating up, no phone is immune if the software is not well optimized or if there are uncontrolled processes.
  • Intensive Use: Games with demanding graphics, heavy multitasking, or prolonged use of the camera (especially recording video at high resolution if available) can generate a lot of heat.
  • Battery Issues: A defective or highly degraded battery can generate more heat than normal during charging and discharging.
  • Environmental Conditions: Using the phone under direct sunlight, in very hot environments, or with a very thick case that does not dissipate heat well.
  • Hardware Failure (Motherboard): In rare cases, a short circuit or a defective component on the motherboard could be the cause of extreme overheating.
• Solution:
  • Close applications you are not using that may be running in the background.
  • Reduce the screen brightness and consider using the 60Hz refresh rate if the phone heats up a lot with 120Hz.
  • Avoid using the phone for very demanding tasks for extended periods without rest.
  • Do not use it under direct sunlight or in very hot places. If you are charging the phone and it gets very hot, disconnect it for a while. Especially avoid using it for gaming while charging.
  • Remove the case if it seems to be contributing to the heat dissipation problem.
  • Ensure both the operating system and apps are up to date (with the caution already mentioned about updates).
  • If overheating is persistent, severe, and occurs even with light use, it could indicate a battery problem (consider replacing it) or, in the worst case, a hardware failure on the motherboard requiring technical attention.

Charging Port Failures ? No Connection! ?

The symptoms and causes of a defective charging port (not charging, slow or intermittent charging, needing to move the cable, data transfer issues) were already covered in the spare parts section. They are generally due to physical wear of the port, accumulation of dirt or lint inside, or a defective charging board (sub-board). The solution is usually to carefully clean the port (with the phone turned off and using a non-metallic tool like a wooden or plastic toothpick, or compressed air) or replace the charging flex/bottom board.

Sound Issues (Speakers, Earpiece) ? Hello? Can You Hear Me? ??

• Symptom: Low, distorted, crackling sound, or completely absent sound through the main speaker (multimedia) or the top earpiece during calls.
• Likely Causes (Hardware/Software):
  • Dirt/Dust Obstruction: This is a very common cause. Speaker grills can accumulate dust, lint, and other debris over time, blocking sound output.
  • Damaged Speaker/Earpiece: The physical component (speaker coil, diaphragm) may have been damaged by a drop, liquid exposure, or simply by component failure.
  • Software/Connection Issue: A bug in the software, a conflict with an app, or a loose internal connection of the speaker module.
• Solution:
  • MIUI "Clean Speaker" Function: Xiaomi includes a useful software tool to try solving mild obstructions. Go to Settings > Additional Settings > Clean speaker. When activated, the phone will play a high-pitched pulsating sound for a few seconds, designed to expel dust particles. It is advisable to repeat the process several times and, if possible, with the speaker facing down.
  • Manual Cleaning (with care): If the software function is not enough, you can try gently cleaning the speaker grills with a soft, dry bristle brush (like an old, clean toothbrush) or with compressed air in short bursts and from a safe distance.
  • Verify Settings: Ensure the volume levels are correctly adjusted and that no "Do Not Disturb" or silent settings are accidentally activated.
  • Test in different applications to see if the problem is general or specific to an app.
  • Component Replacement: If cleaning and software adjustments don't resolve the problem, the speaker or earpiece is likely defective and needs to be replaced. On iLevante.com, you can find "Redmi Note 11 Pro 5G earpiece speaker" or "Xiaomi Redmi Note 11 Pro 5G buzzer speaker".

Proximity Sensor and Black Screen During Calls ??

• Symptom: During a call, the screen goes black when bringing the phone close to your ear (which is normal) but does not turn back on when moving it away, preventing hanging up or using the keypad. Or conversely, the screen does not turn off when bringing it close to the ear, causing accidental touches with the face.
• Probable Causes (Hardware/Software):
  • Virtual Proximity Sensor (Software): The Redmi Note 11 Pro 5G uses a "virtual" proximity sensor instead of a dedicated physical one. This system relies on algorithms and may use other sensors (such as the front camera or gyroscope) to infer proximity. These virtual systems can be less reliable than physical ones and more prone to bugs or miscalibrations in MIUI.
  • Screen Protector/Dirt: A poorly placed screen protector, low quality, or dirt accumulated on the top of the screen (where the system "expects" to detect proximity) can interfere with its functionality.
  • Miscalibration or Software Bug: The sensor might need recalibration, or there could be a bug in the software controlling it.
• Solution:
  • Cleaning: Thoroughly clean the top part of the screen, where a traditional proximity sensor would be located.
  • Screen Protector: Try temporarily removing the screen protector to see if it?s the cause of the problem.
  • Calibration: Look in Settings for any proximity sensor calibration option. Sometimes this option is hidden in developer menus or the CIT menu (accessible as described for the camera).
  • Call Settings: Within the Phone application, go to Settings (gear icon or three dots) > Incoming call settings. Some MIUI versions allow disabling the proximity sensor during calls. If you disable it, the screen will remain on during calls, so you?ll need to manually lock it to avoid accidental touches.
  • Permissions and Updates: Ensure the Phone app has all necessary permissions. Keep MIUI and the Phone app updated.
  • Reset App Preferences: As a last software resort, try resetting preferences for all apps (this won?t delete app data but will reset permissions, restrictions, etc.).
  The virtual nature of the proximity sensor in this model means solutions are often software-based or related to obstructions affecting the sensors the algorithm uses, rather than a discrete physical component failing.

Severe Failures: Motherboard Issues ? The Heart of the Problem ?

• Symptom: These are the most serious problems and can manifest in various ways:
  • The phone does not power on at all, showing no signs of life (sometimes called "sudden death").
  • Constant and unexpected restarts, or the phone gets stuck on the Xiaomi or MIUI logo during startup.
