do OEM unlocking save battery

OEM unlocking is a feature in Android devices that allows users to unlock the bootloader, providing them with more control over their device's software. Unlocking the bootloader can potentially allow users to install custom firmware, modify system files, and perform other advanced operations.

Unlocking the bootloader itself does not directly affect battery performance. However, installing custom firmware or modifications can have an impact on battery life. This is because custom firmware may not be optimized for power efficiency, and certain modifications or apps installed may consume more resources, leading to increased battery drain.

It's important to note that OEM unlocking is an advanced operation and should be done with caution. It may void the device warranty, and incorrect procedures or modifications can potentially lead to problems with the device.
