Here you’ll find the spare parts available for the Motorola Razr 40 Ultra, the 2023 clamshell foldable that launched with a 3.6-inch external display, the largest on any flip phone at the time. We stock the complete display in Original quality, the 3800 mAh battery assembly and the original USB-C charging port. These parts are useful both for individuals repairing their own phone and for repair shops that need precise references for every order.
XT2321 codes: how to identify a Motorola Razr 40 Ultra and its twin, the Razr+ 2023
All Razr 40 Ultra variants belong to the XT2321 code family. The international version sold in Europe is the XT2321-1; the XT2321-2 was certified for the Chinese market, while the XT2321-3 is the Motorola Razr+ 2023 sold in the United States. An XT2321-5 variant also appears in certification records. These are the same phone, sold under different names depending on the country; if your code doesn’t start with XT2321, you’re not looking in the right category.
To check on the phone itself, go to Settings > About phone and look for the regulatory or model and hardware information section, where the full code is displayed. It’s easy to recognise from the outside: when the phone is closed, the external display covers almost the entire top cover.
Don’t confuse it with the Motorola Razr 40, launched at the same time. That model has an external display of just 1.5 inches, its inner display runs at 144 Hz and its battery is 4200 mAh. Although they’re a similar size when closed, its displays and batteries are not the same as the Ultra’s, so check the code before buying.
Which replacement part your Motorola Razr 40 Ultra needs, based on the fault
If the 6.9-inch foldable display is damaged
The Razr 40 Ultra’s main display is a 6.9-inch foldable pOLED with a resolution of 2640 x 1080 and a refresh rate of up to 165 Hz, protected by a layer of ultra-thin glass beneath the outer film. It’s the most fragile component of the phone, as it incorporates the fold and the entire touch surface.
The original complete display for Motorola Razr 40 Ultra is Original quality, so it retains the factory panel’s performance: 165 Hz, brightness and colour reproduction. A practical detail: the fingerprint reader is located on the side of the frame, not under the glass, so replacing the display won’t affect fingerprint unlocking.
Keep in mind that this model has two separate displays, an inner and an external one. Before buying, check the product listing to make sure the part is for the display that’s damaged and to see which components are included, as this affects the fitting process.
Two cells with a combined capacity of 3800 mAh
The Razr 40 Ultra doesn’t have a single battery, but two cells: a main cell with the reference PM29 and a smaller secondary cell, PM08. Together they provide a typical capacity of 3800 mAh; the 3640 mAh figure shown in the certification is the nominal capacity of the same assembly, not a different battery.
The 3800 mAh battery compatible with Razr 40 Ultra and Razr+ is Premium quality, a compatible alternative at a lower price than the official replacement, and is listed with the references PM08 and PM29. Check these references against those printed on your phone’s cells and see in the product listing whether the item includes the complete assembly or just one cell, especially if you only want to replace one of them.
When the phone stops charging by cable
The Razr 40 Ultra’s USB-C connector supports 30 W TurboPower fast charging (the charger supplied in the box was 33 W) and is also used for data connections to a computer. 5 W wireless charging doesn’t use this connector, so if the phone charges on a wireless charging pad but not by cable, the connector is the main suspect rather than the battery.
The original USB charging port for Razr 40 Ultra is Original quality, the same part fitted in the phone at the factory. It’s the right choice if you want to maintain the model’s fast charging without using adapted parts.
Adhesive-backed cells and IP52 certification: specific features of the Motorola Razr 40 Ultra
Published teardown reports show that the two cells are glued in place and have no pull tabs, so removing them requires patiently dissolving the adhesive without deforming the batteries. This is a job better suited to a repair shop than a first attempt at home, and it’s worth bearing this difficulty in mind when deciding who will carry out the replacement.
Out of the box, the phone has an IP52 rating, which only protects against dust and light splashes. Once the phone has been opened, this protection depends on the seal applied when it’s closed again, so it shouldn’t be assumed to remain guaranteed after any repair.
Frequently asked questions about Razr 40 Ultra and Razr+ 2023 parts
Will Razr+ 2023 parts fit the Razr 40 Ultra?
Yes, because the Razr+ 2023 (XT2321-3) is the same device sold under another name in the United States. That’s why the battery in this category is listed under both names. Even so, check that your code belongs to the XT2321 family.
Can I fit the battery from the standard Razr 40 in the Ultra?
No. The standard Razr 40 uses a 4200 mAh battery with a different configuration, while the Ultra uses the PM29 + PM08 assembly. Check the references printed on the cells, not the physical similarity between the two phones.
Why do some websites show 3800 mAh and others 3640 mAh?
These are two ways of measuring the same battery. 3800 mAh is the typical capacity stated by the manufacturer, while 3640 mAh is the nominal capacity listed in the certification. Both figures refer to the combined capacity of the two cells.
Can I replace the inner display myself?
Yes, although it requires pre-cut adhesives, delicate tools and a clean, static-free work area, as well as extra care when handling the fold. If you don’t have experience with foldable phones, it’s best to use a repair shop.
