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

To reassemble your device, follow these instructions in reverse order. '''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 [[E-Waste|R2 or e-Stewards certified recycler|new_window=true]]. Repair didn’t go as planned?
