Battery with connector for connecting the original BMS without soldering

Specially designed battery with a connector for connecting the original BMS without the need for soldering. The original BMS must be removed from the original battery and connected to the new battery's connector. With the original BMS, the phone will not display a battery replacement warning and will continue to show the battery's condition.

The following procedure is intended for specialized service with appropriate equipment - before replacing the battery, we recommend discharging it to below 10% capacity. Failure to follow the proper procedure may pose a risk of injury or fire.

If your battery is swollen or shows other mechanical damage, please contact a service center.

Replacement procedure:

1) Remove the original battery and carefully detach the BMS insulation.

2) Using scissors, cut the BMS from the battery terminals

3) Connect the BMS to the connector and insulate it with the included strips

If the battery was replaced in a phone with iOS 17.3 or earlier, a battery replacement warning will not be displayed, and the battery condition in settings will be 100%. The phone can now be updated.

If the phone has already been updated to iOS 17.4, it is advisable to downgrade to 17.3, perform the battery replacement, and then update. 

If you have iOS 17.4 and replace the battery, the battery replacement warning will not be displayed, but the original battery condition will remain in settings.

If the phone cannot be downgraded, the battery replacement warning and its condition can be adjusted using the 3Utool program. It is recommended to back up your data first.
