This replacement battery is what you need to bring that dead smartphone back to life.
This battery is brand new! Each one has been tested to confirm that there are no cycles on the cell and that the capacity is 95% or higher.
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%.
After replacing your battery the Battery Health feature on your phone will display "Service" and a message about needing to have your phone checked by an authorized service provider. Rest assured that the battery and your phone are fine. iOS shows this message anytime a battery is replaced by anyone other than an authorized service provider. Your phone will function 100% normally other than Battery Health not reporting the health of the battery.
