I get max three days but average two on my 6S running 13.3. I like 13 myself. A welcome change from the iOS 7 look by far. Especially at night. Makes me crave an X or 11 since the bottom bezel kinda doesn't look like it belongs on a 6S; software looks like it wants a seamless bottom.

I like the Pro's of IOS 13 but the con is 2 hours of battery life (for me) instead of the 24 hours.
 
Who suggested force closing anything? If i do swipe anything away in the recent apps it's because after awhile it gets cluttered with tons of stuff.
 
I spoke with apple support this morning (via chat support) who denied that the issue is anything to do with IOS 13 and was 100% due to battery health. Even after I advised that the handset was fine the day before upgrading to IOS 13 (it really wasn't an upgrade).

The support opp I spoke with said that they were convinced that a new battery would resolve my problem. I asked if there was anyway to say the chat transcript , to be told it would be emailed to me ( it hasn't ). I was keen to keep this as evidence should Fridays planned battery replacement turn out to be a waste of money.

Fingers crossed

I had my battery replaced by apple and have to say that it resolved the problem. I was very skeptical due to the issue only occurring after the upgrade to 13.xx.
 
Seriously? 85% battery capacity and you guys are going down a rabbit hole?

Pay $49 and get the battery replaced.
 
The best thing to do is just ignore the stupid health 'feature' and use your iPhone as you've always done in the past.
