I do not believe the mah measurements are accurate. However, I cannot find an app that accurately displays my charging speed, so it may be impossible. All other aspects of this app are truly amazing! Edit: Working with the development team to resolve the issue.

Deep sleep doesn't work sometimes. Please fix this. And also please add an online backup option for all our charging and discharging records so that we can't lose our records even after removing the app.
Vince Wardman
This is a pretty great little app. I couldn't get my phone to cool down so I went searching for apps that detect battery usage. This one was actually able to cool my phone down even after a factory reset couldn't.

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".

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.

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.

A great battery app. The notification details. The protection features. The optimization. Evrrything works fine and the reading is accurate too. Definately recommending who want to save and properly use their battery.

All I can say is that this app is legit,it really determined how long my battery was gonna last,my phone often overheats when I play huge games,but when I checked how to save battery online,I ran into the 5 apps,this one was the best and I played a game for hours and my phone didn't overheat .5 Stars. ✌✌

Still exploring the whole functionality but it has been great experience so far. Thank you for your hard work Wishing that it could directly make a charge cut off but it seems like this is out of the scope
