iPhone 6(S)/Plus Battery quickly discharing despite 98% Battery Health

[ulf01]

My iPhone 6s got a new battery about a year ago from a licensed Apple dealer.
Battery health is now 98% and I very rarely discharge below 20%.
BUT I experience since a while that I can barely use the phone for more than 2-3 hrs until I have to recharge. I am using no special apps, mostly news and internet browsing. Please see that attached Battery Level Diagram which is pretty much typical. I think on should expect better battery performance, right?

Probably a stuck processing loop - have you tried restarting your phone? May need to do a full restore.

I think so too. Check out the list of apps using battery, just below what you showed us. Your top app looks like Safari. See anything unusual there?

There are not suspicous apps running and I have already done restarts without effects.

Put coconut battery on your Mac

Plug the phone in via usb

What’s the cycle count / % ?
