Good, but...

On my Xs Max it’s really hard to hit the < and bars in the top left for some reason. At first I thought maybe my screen had issues but I tried other apps and the screen is fine, seems there’s an issue with this app.

Otherwise, does what it says. I got it because I wanted to verify fast charging speeds for my phone since the beeps never work.

Zero amps? Really??

I usually have very low expectations for free apps but this app failed to even come close to meeting them. With the phone at less than 80% as instructed, plugged the phone in and ran the 3-10 minute test.

It's obviously charging, I can see that based on the battery icon from ios. After waiting, and waiting then waiting some more the test results are finally available. "very slow" with 0 amps registering is the apps conclusion. In other words, it's not charging. Clearly, it is. The developer is either completely clueless or had a major bug that he failed to catch when testing his app.

Seriously, don't waste your time... You'll never get that 3 to 10 minutes back that it takes the app to tell you absolutely no information. You can get useless information by watching a white house press need to install this to get more.

Fixed my iphone charging

Could not charge my IPhone 6s
With either of the two charging cords i have always used. Cleaned all contacts and charging port looked fine. After several hours of trying i gave in and scheduled visit to repair shop. Downloaded this app to check the charging and battery. After starting, it asked to diagnose system...and caution that it would take several minutes. When it finished, it declared battery OK and commented that charging was slow. Slow? It started charging and as fast as always. THANK YOU SIR!
