Die Anzeige erfolgt aber nur in 5%-Schritten. Das finde ich zu ungenau, da die Daten ja vorhanden aber nicht komplex ausgewertet werden. Da ich zu den sogenannten 80%-Ladern gehöre, um den Akku zu schonen, wäre mir eine detaillierte Anzeige und am besten noch ein Signalton bei genau 80% Ladekapazität wichtig. ### 4/5 — Just works. And works well. Minor request. *2023-08-08, version 1.4.9* Actually I’ve looked and looked for an app which would record the % of my iPhone every x number of minutes. There are literally none that I’ve come across which can do it. Then I came across this app, which records iPhone battery percentage of a period of time, which is exactly what I wanted. The only thing I’d say is, please can you allow me to see the % over time on my iPhone (currently you can only view this on the Apple Watch), I need to be able to scroll through % vs time on my iPhone. And secondly, please would it be possible to have the app log battery % every user definable period, for example set it to log iPhone battery % at 1pm, 1:15pm, 1:30pm, 1:45pm etc etc ? That would be amazing. I can’t believe no other app in the App Store does it. ### 4/5 — works great *2023-06-29, version 1.4.9* overall this does work great. however the times are downright inaccurate, and the app doesn't refresh unless you close the window and re-open it. ### 2/5 — Premium doesn’t work *2023-05-10, version 1.4.9* I paid for the premium version of the app but it doesn’t give an alert when the phone is fully charged. ### 5/5 — Tried all battery apps that work on watch *2022-12-09, version 1.4.9* This app works well and does not drain the battery significantly compared to the rest. ### 5/5 — Great App! *2022-11-26, version 1.4.9* Indispensable!

The percentages % were always spot on . ### 5/5 — Chow-4paws *2022-10-04, version 1.4.9* I just love this app. Just to know how much battery charge you have left is just fantastic…especially if you are going somewhere (where you can’t charge your phone)…..A big THANK YOU for this app!.🤗 ### 5/5 — good app *2022-09-25, version 1.4.9* 10of10 ### 4/5 — Battery status in % would be nicht *2022-09-16, version 1.4.9* I use this app to see my iPhone‘s battery status on my Apple watch.
