Works great on Galaxy S3 This app tracks and displays exactly what is going on with the charging/battery system. I wanted to compare various chargers to see if there was a difference in performance and this app was exactly what I was looking for. Many parameters are adjustable so you can tweak it to your needs or if you're newbie you can just use the setup wizard. Minimal battery drain for all that it does.
Became a processor hog Was running just fine until the latest update from AT&T. Now, have to spend about 20 minutes each morning trying to get this app's usage of the processor to drop below 10%. Then, have to repeat all over again the next morning (withOUT having rebooted the phone). This is on GS5 Active, and monitoring with Usage Timelines Pro. Been loving this app for a long time. Will return to positive rating if dev gets it fixed, but cannot recommend at this time.
a great app but... the app is great it helps you know the time left for you doing each activity before your battery runs out but i have a problem some times there is missing data at the history tap it varies fro several minutes to about 16 hours. overall it an amazing app i recommend it for every one
Great app, but... The battery/charge flow rate is way out on the HTC One M9. Please fix.
Great app Been having trouble with battery drain on my Tab S and this app helps me monitor it the whole time I'm using the tab. Must say battery has improved a bit since updating to Lollipop.
Inflexible Seems to be a pretty good app but I can't find a way to change the temp setting to Fahrenheit. Will be using one that does.
