Compatibility
Fits the Motorola Moto G Stylus (2021), model numbers XT2115 and XT2115-1. It does not fit the Moto G Stylus 2020, 2022 or 5G versions, which use different batteries. Find your model number in Settings > About phone.
Before you fit a replacement battery
- Check the battery code: match the model code printed on your old battery with the one on this listing.
- Discharge first: run the old battery down below 25% before you open the device, which lowers the risk if a cell is damaged.
- Never puncture or bend: lift the old battery slowly, using isopropyl alcohol to soften the adhesive strips.
- Calibrate: after fitting, charge to 100%, use the device normally, then give it a full charge again so the percentage reads accurately.

Frequently asked questions
Will this fit the Moto G Stylus 5G?
No. The KX50 is for the Moto G Stylus 2021 (XT2115). The 5G and other years use different batteries.
What is the KX50 code?
KX50 is the Motorola battery code for this phone. It is printed on the old battery, so you can match it before ordering.
Why does my Moto G Stylus show the wrong percentage after fitting?
A new battery needs a couple of full charge cycles to calibrate. Charge to 100%, use it down, then charge fully again.
How fast will it arrive?
Orders placed before 4pm, Monday to Friday, are dispatched the same day from Manchester.
