Ratings and reviews

I am running android 16 and the app does not start when I plug in the charger. I have to open it, change settings numerous times, start when plugged in or start when screen sleeps. it works then but not the next time. I have another device android 13 and it works seamlessly

this is really a fantastic app very detailed, that i purchased ad free version. but could you add cycle count in your next update. as I have Samsung galaxy s26 ultra. the.

Been using OneBattery for a minute now, and honestly, it's solid. I mostly use it to test my cables and make sure my charging bricks are actually outputting what they claim on the box. It’s pretty damn useful for keeping tabs on what's slacking off and what's actually working. Definitely a good form of quality control for your gear. I highly recommend it.
