The overnight summary is fairly useless without information about what caused the wakes. Ok, so it woke up 12 times. That alone is not actionable.

I'm honestly impressed at how often this app gets updated. And with each update, it gets better and better. The UI gets even more beautiful with each update. I have replaced my old battery tracker app and doze manager app with this one app. And it does more than those two combined! Absolutely love it.
Pratham Desai
Easy and beautiful UI , it's good that no feature is hidden behind subscription. Hope it stays like this. I don't mind the ads. Edit: the new UI sucks, it's not easy to access the information, everything is hidden behind clicks which makes it inconvenient

Thanks for the app. I am using this app along with your speed indicator and after the latest update both of there notification icon are fighting for the priority please help as it is a bit annoying to watch both icons continuously "shifting".

Works great. Accurate with a lot of info. I just wish there was a one-time purchase option. I generally refuse to subscribe/rent software, but if the yearly amount was less I would make an exception for this app.

It really helping to save battery for Android 11 when few apps prevent Android to into deep sleep. The Lite doze options is very difficult to understand, please provide option to disable all lite doze settings as most people want deep sleep after screen off.

Hello, will the app be updated in the future to accurately report capacity for split cell phones such as my OnePlus 7T? I have entered half the design capacity as a work around, but this really isn't a proper solution. Otherwise your app is well written and highly useful. Thank you!

It includes everything I want. The battery status notification shows the discharge current and temperature, very useful for monitoring while using another app.

I update this review, after long development this app already has all the core features plus some additional features all for free. After accubattery development seems to be stop, this app finally can replace that.
