Excellent app for whatever you need to know about your device's battery, charger, charging speed and all. Useful features available for battery protection like level alarm, temp alarm etc. Have been using it since 2.5 years in every phone I own. Definitely recommended whether you are a basic or advanced user.

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

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.

I wish the notification for charging threshold can use custom ingtone or custom a tone. I always missed to charge 80%. Overall this a great app. Good job!

Tried many of these proved to be the best. An application that makes it worth unlocking the bootloader and routing your phone. Battery life has increased significantly.

Clearly this is the best app. Legit stats and even support for dual battery too. The BS features and all of the features are useful and updates keep coming with more optimisations. Loved it and satisfied with this. Highly Recommended! And thanks Dev, keep up the good work ❤️

Thorough reporting of battery stats. You can enable temperature and battery heat thresholds and be notified. One quirk, the app shows which apps are using the most power, but it doesn't show this all the time. I haven't discerned a pattern as to when this report is available.

I'm amazed how much you have upgraded your app, keep up the good work, excellent job, with the new power saving options you are killin' it, I have it as my main battery app 5/5 and 10/10
