I was getting odd results from this app on my 2 year old Note 10. One day it would say my battery was only 70% good the next 90%. In the end I deleted the app and bought a new S22. The battery on that lasts about the same time as the Note 10. The only real improvement of the 22 over the 10 is that the fingerprint recognition is much better and the USB port works because it is not full of pocket fluff.
