Amperes 3 - Battery Life Info

Buy Pro Upgrade

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.

Due to iOS17 maybe?? Tests take forever now, results are way off from prior tests with the same gear.

A must to have.

Completely inaccurate readings and it claims my brand new 20, 30, 60, 90, watt chargers from Apple only output 10.5 watts on my new iPhone 12 Pro Max.

What’s the difference between “Amperes” and “Amperes 3” app? I bought Amperes 3. Both are from the same developer and seem to do the same thing. Did I purchase the wrong app?

Great app. I thank you. Now I can test my chargers and cables.

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

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.

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!
