Great at testing chargers, but timer alert is off
Others have mentioned that when testing, you get no indication how far along the testing is.
In addition, after clicking start., it can take awhile (enough to charge 5%) before the test actually starts running.
Lastly, it’s really important when comparing chargers to test them at the same battery % on the phone (since iPhones charge slower at higher %). There is a timer function to alert you when the battery hits a certain % to account for this. Unfortunately when I set mine at 30%, it alerts me at 26%. Not so helpful.
Response from developer
Thank you for your review! Unfortunately you are correct about 5% and slow times. In iOS 17 Apple changed the way how they report battery charging to app developers. Instead of 1% increase it's now doing it every 5%. As a result, all tests are at least 5% slower than before. Battery percentage reported is also not correct. Its given in +- 5 from the real number.
