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.

What you need

Step 1

              Heat the rear glass
  • Before you begin, switch off your phone.
  • Apply a heated iOpener to the back of the phone to loosen the adhesive beneath the back cover. Apply the iOpener for at least two minutes.

Step 2

              Insert the iFlex
  • Secure a suction handle to the bottom of the rear glass, as close to the edge as possible.
  • If the phone’s rear glass is cracked, the suction handle may not stick. Try lifting it with strong tape, or superglue the suction handle in place and allow it to cure so you can proceed.
  • Lift the rear glass with the suction handle to create a small gap between the glass and the frame.
  • The rear glass of the Xiaomi Mi 10 sits tightly in place. In order to create a gap that is big enough to insert an opening pick, you need to insert an iFlex first.
  • Insert the iFlex into the gap and leave it in place to prevent the adhesive from resealing.

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. Apply new adhesive where necessary after cleaning the relevant areas with isopropyl alcohol (>90%).For optimal performance, calibrate your newly installed battery.Take your e-waste to an R2 or e-Stewards certified recycler.Repair didn’t go as planned?
