Confirms my chargers are truly working right Love that I can see if my chargers are operating properly by monitoring mAh in and if my USB cable is adequate for fastest charge speeds. I've sorted out crap cables and chargers with this tool. What could make this tool 5 stars? If there is any chance of showing that the QuickCharge 2.0 is working properly and the USB port is running at 9 or 12V, that would be awesome.
A battery drainer itself On my Xperia Z2, this app causes the phone to go from 90% to less than 70% sitting idly on my bedside table over about 6 hours. I deleted most other apps, turned off Bluetooth and tap to wake etc, nothing helped until I found proof that this battery app is responsible for the drain. I like to see the battery stats but cannot accept the irony of the battery management app using the most power of all my apps on the phone. Deleted
Lots of data Provides a ton of information on battery use. Would be even nicer if one could have multiple estimates on notification. Support for estimated battery life left from past x minutes would also be nice. For example Gsam allows you to see estimates for average and past 15min at the same time on the notification.
Problem with notification packages While it's good to have graphical notification package (downloadable .apk from the app. It shows you charging current, voltage, etc), it seems incompatible to the recent app version. Otherwise, this app is really great!
Pretty good Does a lot and is very helpful. One simple thing I wish it did though: Show actual input mAh not just: (input - drain = current flow). I want to know how much my charger is actually providing the device.
Material design? LOL - not sure in what world... Or you must be smoking some quality shiate if you're seeing material colors in your app Mr developer Dedicated developer with an optimized app This is a great app to troubleshoot your battery woes and app drains. Coupled with Watchdog you can identify battery hogs. For e.g. I just found out that the Coyote Live Wallpaper spikes to 40% of CPU from time to time which is not acceptable.
