Ratings and reviews

Love it!! Such a simple app and nice layout. I've seen other apps but this is by far the best. Does exactly what it says and works fine. I really like the fact you can choose what percentage you want. What ringtones, how long for and it even tells you what range is good for battery life. It even shows temperature and how long left to charge.

Good app, though there is a few bugs. Every time I change the Alarm Sound, my phone alarm volume is suddenly set to 100%. The app should let the system alarm volume as is. In the settings, the select/dropdown closes itself almost immediately after I opened it. I can still select from it for a few moments, but it's still quite annoying. Also apparently the charging speed is reversed, it shows negative value when charging and positive when discharging. If these issues are fixed I'll give 5 star.

just make consume less battery and less SoC & RAM
