Battery Drain iOS 13.1.2 on iPhone

I have upgraded my iPhone 7 plus to iOS 13.1.2. The battery life is not up to the mark. Earlier the battery would run from 100%to 35% for 24 hours with moderate usage. (Battery drains to 50% for 8 hours even when there is no usage at all/no SIM card/ no application installed/background app refresh is turned off/power saving mode is turned on). I tried the following

waiting for 4-5 days believing that indexing will complete
complete factory reset
completely uninstalling all the apps and keeping the mobile as fresh without any data
keeping the mobile in flight mode

But the battery drain is same in all cases. Is this the fault of iOS? My iPhone battery performance is 89%

Thanks for your view and answers.

I spoke too soon. After 13.1.3, the battery does last a couple of hours more, but still fall short of 10 hours under light use.

So problem still exist.

My son works in an electronics department and most people want iPhones, but since the upgrade he’s sold his first Samsungs. People are fed up.

I have the same problem. Upgraded my 6s plus to 13.2 and the battery life got even worse. No solution at all. I watched it dropping from 60% to 33% in seconds.

There is no "story".

What is the battery health on your 11 month old battery?

No story? My battery health is 91% - but capacity goes from 100% to 50% in one hour.

Good luck, mate. That is exactly what the apple genius did to my IPhone 6s. It didn't work.

Two days? I just walked for one hour listening to music and ate 70 percent of my battery.

You're kidding.

Oh dear that's not great news either. I will have to update, as I have my follow-up call on Sunday and unless I update it, the suggestion will be made to do so to solve the issue, so here goes...

You are absolutely correct and my symptoms are identical! It's a software glitch Apple must fix.

Nov 17, 2019 7:01 AM in response to marine1948

Nothing for Apple to fix.

I have all the new updates for my 7. It’s made no difference. Battery still drains when the phone gets hot.
