There are many many different android apps that measure the mAh’s your phone battery is receiving while being charged.
I tried : Ampere , Ampere Meter , AccuBattery and they all say something else.
With differences up to 500mAh!
What app do you recommend to use for measuring your charging speed precisely?
I’m currently using Ampere, and usually it agrees pretty closely with my USB current meter . Granted both app & meter were pretty cheap, so I can’t say which is more accurate!
Subbed to watch other responses…
I tried a ton and the only one that worked reliably and accurately was 3C Battery Monitor. It logs and graphs, has many other useful metrics, and the widget is actually useful and customizable.
Update: Ampere stopped measuring current draw and charge when my Moto X Pure’s OS updated to 7.0 a few weeks ago. I mentioned it in my review, but the app designer never responded.
