Заключение

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 2 more hours. Then use your device 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.
