I used Du battery saver pro before, But then I changed my phone to Redmi 2. There's already battery app setting from Redmi 2 to do the scheduling n create profile modes, just like what I used from Du battery saver. So, I just need a battery app showing statistical graph of my battery use, n found this app which serves the purpose. It works to what I need, n it's very light on storage n ram. However, it still lacks detailed stats like Battery sense app on my windows phone. I wanna buy full version, but this app isn't actively supported anymore
I think it's a pretty awesome app, but developer should give user option to adjust resource usage. There are many ways to implement that. I'll probably send an e-mail about it. Buying the paid version will probably depend on it, I don't know.
I really like it, but..... There is no way that I can find to kill the battery indicator in the notification bar.
To many adds This is a really good app but there are a little bit to many adds
Battery Spy for the win This is one of the best, if not THE best battery management apps on the Google Play store. I downloaded a bunch of them to test drive, and this one was my favorite. The free version is fully functional, but it's totally worth the $1.50 for the paid licence in my opinion. Developers who build quality software deserve support.
