Plus Plus Battery

Plus Plus Battery Battery app for Android description

PlusPlus Battery gives you everything you ever wanted to know about your phone’s battery — from simple level and power readings to deep-dive metrics. It is designed and tested on modern OnePlus/Oppo/Realme devices, but also works on most recent AOSP-based ROMs.
