Nice Things About Us
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.
MD Tahsin Hossain
5+ stars for sure. It shows phone charging information accurately. Also the battery health is 99% accurate. Also it shows charging speed (in Watts) is a charm. Keep it going developers.
Joon Keat
Currently the best battery app that combines all the useful features from other battery monitoring/dozing apps. I'm obsessed with monitoring my batt and this is the only app I needed and have uninstalled a bunch of other apps.
Watson Anaem
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.
Subhanshu Mohan Gupta
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.
Shaun
Actual, legit, full-fledged battery and power management app without requiring root (some ADB commands required). It's not like those 1 or 2-screen useless stuff. It's up there with Accubattery and even better because of integration with battery saver and doze management.
William Scott
Pro app no ads, the app is the Best battery manager I've used in all my time using Android. My only recommendation allow white list of a certain app or apps if you enabled data saver to not sleep those apps
Demon Boy
This app is great, recently I install custom rom and the battery percentage was showing inaccurate readings. I only have one problem that is the notification of this app doesn't show on top of any other notifications even after turning notification priority on, please fix this.

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
