Does exactly what it's supposed to do. I frequently switch between a standard battery and an after-market with 3x the Mah. It confuses my phone and it dies while still displaying 30%charge. Calibration with this app when I switch fixed this. Big thanks to the Devs.
This app is smarter than smartphones & smartphone batteries. It's very effective at keeping batteries properly charged, so device owner's may avoid unnecessary battery replacements. I encourage all my friends to install it on their smartphone, and to tell other's how it works for them. So far, ALL have shown improved battery performance. The device owner's are all quite surprised, and very pleased.
What I first noticed that I like a lot is two things that 99.9% of the apps on Google Play marketplace lack. #1.) A video, however short or long, that contains an introduction: background, purpose, target audience, features, and/or other related facts, and directions.....A succinct video that is automatically played. #2.) is the take away-->The PDF document with things to learn about mobile device batteries. Wouldn't it be great if all apps had similar resources in-app? Sometimes no guidance is the best way to learn but I prefer the way I learned how to work this app. I'll update once I'm finished calibrating.
Wish the UI had a black/material dark base theme.. Hate light color backgrounds. Reminiscent of iOS blandness, when light themes are used. I hate bland, Apple style, eyesore causing, light colors. =·\ Other than the UI, the app is stellar, however. ;·»
It's simple and easy to use. I've just started using it and it seems to have solved the problems I was having...
All I can say is that since I have been using this app for a while that my battery is running much better than before. I strongly recommend that you get it.
