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, '''[[Battery Calibration|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 [[E-Waste|R2 or e-Stewards certified recycler|new_window=true]].
