    • Secure a suction handle to the lower edge of the rear glass, as close to the edge as possible.

    • Lift the rear glass with the suction handle to create a gap between the glass and the frame.

    • Insert an opening pick into the gap.

결론

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

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 phone 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: Charge it to 100%, and keep charging it for at least two more hours. Then, use it until it shuts off due to low battery. Finally, charge it uninterrupted to 100%

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

Die deutsche Übersetzung war veraltet, ich habe sie aktualisiert. Danke! Viel Spaß mit deinem Xiaomi.

Danke für die Anleitung erstmal. Ich habe jedoch die Keramik Version des Mi8 und bei mir scheitert es bereits beim Anheben der Rückabdeckung. Diese gibt quasi überhaupt nicht nach und ich bekommen kein Spektrum dazwischen. Irgendwelche Tipps?
