Introduction

If your battery is swollen, take appropriate precautions. For your safety, discharge your battery below 25% before disassembling your phone. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair.

You’ll need replacement adhesive to reattach components when reassembling the device.

  • Before you begin, switch off your phone.
  • Insert a SIM eject tool or a paperclip into the small hole on the SIM card tray on the left edge of the phone.

  • Remove the SIM card tray.
  • When reinserting the cards, make sure to properly orient them in the tray.

You can reuse the old adhesive tape if it’s still sticky. However if you want to replace your screen you need to remove it and replace it with new custom cut adhesive tape.

If possible, turn on your device and test your repair before installing new adhesive and resealing.

Secure the new battery with pre-cut adhesive or double-sided adhesive tape. In order to position it correctly, apply the new adhesive into the device at the places where the old adhesive was located, not directly onto the battery. Press the new battery firmly into place.

To reassemble your device, follow these instructions in reverse order.

For optimal performance, calibrate your newly installed battery.

Take your e-waste to an R2 or e-Stewards certified recycler.

I need advice wich battery to buy and from where.

I can’t find a genuine or at least good replacement battery online.

Non of them have a working temperature sensor and most have a lower capacity than advertised.

Xiaomi isn’t selling batteries directly to customers in germany.

Did you find any reliable alternative? Having the same problem at the moment. Thinking about going to one of those repair Shops but actually they probably use the same batteries, that I am finding online.
