I share my experience with iphone user and thanks to iPhone developer that issue resolve of battery drain. In 13.4.1 battery excessive auto drain but yesterday i install 13.5 and i found if i not use my phone so not a 1 percent down and in night battery percentage still the same till morning.
its good for battery health😀😀👏👌👍
I installed ios 13.5 on my 7 plus. Battery health at 93% and the battery drains 4% in one and half hour on standby mode. It drops another 2% when im writing this review T.T . Hope this issue will fix very soon....

I presumed for a long time that Apple would be paying attention to these posts - very disappointing :/
You have lots of avenues for letting Apple know about the problem. You can contact them directly using the Contact Support link at the upper right of every page. You can (in many places) walk into a store and talk to them. You can submit feedback to the Feedback page.

I did speak to a supervisor. Their response was "We already have a case on this, but you need to pay to have it fixed". No joke, they know about the problem but want you to pay them.
So you did get a response, just not one that satisfies you.
We aren't making this up.
No one said you were. You have a problem. What is under question is the cause of that problem.
I posted yesterday that between 9:47 am and about 4 pm I went from 100% charged to 0% and the phone died. The battery health went from 96% compared to new when I did the update to 92% yesterday. Today that dropped to 91%. The charge held a little better today but I'm concerned to see the battery health dropping. The first 20 months I owned the phone it degraded 4%, now after 13.5.1 it's dropped another 5% in so short a time. Maybe the battery is going bad or this upgrade is accelerating that inevitability.
I have 2 issues, quick battery drain and random restarts.
The upgrade is killing your battery...
If you use a CPU meter, you will see that the CPU is running higher than it should.
You can even use common sense to test that theory.. my phone only has a 1650mah battery or something like that. I am charging the phone is drawing 2.1A. With the phone on, it is taking 10 minutes or more per 1%, which means the phone is burning the power faster than it is charging (and yes, I turn the screen off and check every 30 minutes). I shut the phone off and the battery charges from 0 to full in less than 1 hr.
The update is causing the CPU or GPUs to run bonkers, and that is why we are seeing bad battery life.
Lithium Ion batteries have a finite charge ability and also degrade quickly when they get warm. You can only really recharge them about 500 times before you start seeing loss. Since the battery is quickly discharging, you are "burning" the number of charges on it.
Lithium Ion battery failure is also on a logarithmic scale and not linear. It will go from working to not, faster than it goes from excellent to good.
I definitely remember you Fahadnm thanks to you my iPhone seems to be ok ish - however I have put off doing any updates - am waiting for 14 iOS as maybe just maybe all these charging issues will have been dealt with .
watch this space .....
Good that you are happy with the this iOS update however I nerver had an issue with iOS 13.4.1 either.
Its good for u that u have no issue previous version but ibface excessive battery drain issue even in night too. But now fine and hope so it keep
Thank you!
The battery drain started after the update to 13.5.1. // Iphone 7 //Battery health dropped by 5% in a short time.
Went from 86% to 46% overnight with iPad Pro switched off.
Don't agree, we have two iPhone 6s that are now working 100% again with IOS 13.6 :)
iOS battery drain issue resolve in 13.5
