Nice Things About Us
João Pedro
Very complete interface, lots of monitoring to improve battery life. Just amazing. Also liked the way ads are served, in an on demand way for free users. This non intrusive way is much more comfortable for users, trading off revenue. But UX is extremely improved this way.

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.
Michael Clark
Great App! I have a smaller phone with minimal battery life so being aware of all the aspects of my battery are key in maintaining optimal battery health. This App has everything and the ads are discreet and don't interfere with the App operation or function. Excellent!
Nahid Hasan Riad
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.

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.
Savita
Very useful, user friendly. One suggestion. Discharge rate showing correction reqd. MIN shows larger rate of discharge e.g. -657 mah and MAX shows lesser rate of discharge e.g. -156 mah Its because of negative number . Also give another option of one time payment alongwith monthly, weekly options.

I think this app is great! I like the fact that you can assign different sounds or ringtones to different notifications and therefore you are notified when something happens that you should attend to. A very useful app!
Kimchhay Sreng
This app is excellent! It provides detailed battery health information and tracks battery usage very well, making it highly reliable. It comes with many useful and important features that work great, and it's very easy to use. I highly recommend it to anyone looking to monitor and manage their battery effectively.

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
