Just found out the reason why my Apple charger was charging my phone so slow. Bad wire :( Now when I can check and compare wires, few of my beautiful wires ended up in the garbage, because those were beautiful only on the outside. Thank you, Amperes!

Update: I got the app working better and thanks Andre for replying to my initial review and attempting a refund. I upped to 3 stars since I’ve been able to perform and record some tests. If the interface said test below 70% charge rather than 90%, it would solve a lot of initial headaches. How is the user supposed to know that if the app doesn’t say? Also, the tests taking >10 to 20 minutes is a long time to wait when you can’t navigate away from the app during the test. Having an estimated countdown timer or a progress bar come up after 2 or so minutes would be helpful to decide whether to continue or abort for another time. Tried on 2 chargers and it didn’t work on either. My wireless charger charged my phone from 70% to 100% with the test running and the app didn’t record anything. I tried another plug-in charger at battery 87% and the battery icon showing charging. The app says the phone must be charging (check) and the battery must be below 90% (check). The test wouldn’t even start.

Great app with a lot of useful diagnostic tools. I thought my phone’s battery was worsening this past year but it turned out it was a faulty charger. Tested out a new charger and the charge speeds are back to normal.

Very nice app, does what it says and some more! Well worth the 99 cents! :)))
