Good app to see real-time mA - as accurate as it is. Developer: if my phone (Sony z3+) is quick charge 2.0 enabled and I use a qc3 charger with a 5v 3A cable, should the app report 5-12 V and up to 3A charging... Or if 9v-2A at the time it will report 2000ma and that's it? I want to tell if it is quick charging at 3v, 5v, 9v or 12v and an appropriate mA read or if it's just charging as a basis 5v 3a charger. At the time it says nothing about high voltage.. just that it's charging on AC at about 2000mA
This app helped me identify a remote hack. At first it was just a cool curiosity, but now I see it as an added security feature. One of my rarely used apps quadrupled in data usage as well as battery consumption! I seriously doubt I would have noticed without Ampere. Thanks!
It needs a little update. One of the screens says "max. USB current: 1500mAh" while I'm drawing 3 amps over a five volt source. But besides minor issues, this app does measure how much current is going into your phone. It is also very easy to use and I like the layout.
It's good for comparison, but not accurate. I have an inline power meter reading 600mA right now and this app is showing 240mA. I'm not sure what PID it polls for data, but it might be an inaccuracy in the phone software rather than the app. You can use it to get a relative idea of charging speed between different chargers, but absolute accuracy isn't even close.
Fantastic on my Samsung Galaxy S5 Active! Perfect to find best cable/charger combo &/or identify when your cable is not charging well. Small, intuitive, quick App! Does what it says, does not eat battery, or run unnecessarily in background. & Doesn't add on new unwanted features w/weekly updates, morphing into lagging, battery sucking bloatware, like too many other Apps are doing these days. Many thanks to the Dev!
would be great if this app have tracking graph of charge/discharge. so we can see the graph for our whole day or weeks. so we can see how much discharge value we are having everyday and also charging value. I don't really care about graph for battery but i care about graph of amperage/voltage so i can monitor charger and cable performance/status. please reconsider this additional features.

For more info please read the change history: Settings => About Ampere => Change history
Note: When ampere would stuck in "measuring" state (after a firmware upgrade to Android 7.x) please clear Amperes's app cache.
1.) Open the "Android Settings app" => "Apps" => "Ampere"
2.) Clear all data under the "Storage" menu
3.) Restart Ampere
