배터리 라이프 (Battery Life‪)‬ 4+

All these people saying it's inconsistent have zero knowledge of how battery capacity is measured. Yes, the readings will fluctuate, but it doesn't take a genius to know you can just take the average of the readings, which is made easy by the chart and history features of the app. For a true capacity test, you'd have to charge the battery full and discharge until it's empty while watching the current draw over time. iPhones can't really do this very accurately, so inconsistent readings are not the fault of the app. The app is just reporting what the phone is learning about its battery. Under high draw (such as an increased brightness) the voltage sags and the phone has to guess whether it's the battery's internal resistance or it's actually used up it capacity and lowered the voltage. Apple never meant for the user to see these readings, so they fluctuate and aren't really user-friendly. This app just reveals these measurements to give an estimate on remaining capacity. It's a simple, easy to use app that does exactly what it's supposed to do to the best of its ability.

This worked fine until the latest watch and ios updates (8 & 15) Now there seems to be no communication between the watch app on my series 3 and the app on my iPhone 11 Pro Max I've tried uninstalling both watch app and iPhone app and reinstalling without solving the problem. Hopefully the developer will isolate and solve the problem. 9/28 update : I had emailed the developer and have already gotten a reply saying that he knows that there are problems wit the app and ios 15 and is working on fixing them. Update 9/30: Developer fixed the problem and so seems to e working fine again.

This is a very accurate application, i always use it to check the battery on my airpods since sometimes when opening the case it doesn’t always display it on my screen. The only issue I have with it is after i view one different tab and go back an ad is played, like every new action, an ad is played. I dont have a problem with free aps displaying ads, considering it is a free ap and it is most likely the only way they earn some sort of profit. I just dont like how many times it is showed while using it. Other than that, it is a great tool, it updates constantly so it gives you a very accurate read on percentage, theres more to it inside that i havent exactly explored, but so far i think it is a great app and i definitely recommend.
