Redmi 15 screen replacement

The Redmi 15 5G has a large 6.9-inch screen, an LCD type with a 144 Hz refresh rate. When the glass cracks or spots and lines appear, the replacement is of the whole screen assembly, and you can wait at the store in most cases.

Because the screen is bigger than many phones, it takes more impact in a fall. See the Xiaomi screen replacement service and confirm with the team which part fits your version.

Redmi 15 battery replacement

The Redmi 15 5G has a 7000 mAh battery, well above average, with 33 W charging. Even so, after many charge cycles it loses capacity, and a replacement brings back how long the phone lasts on one charge.

If the phone shuts off on its own, gets hot while charging, or the back looks swollen, stop using it and bring it to the store. See the Xiaomi battery replacement service. If the problem is the cable port, see the phone charging port replacement.
