After update to iOS 13.5.1 battery drain is ridiculous and phone overheats

Same problem (iPhone 11 Pro Max) - I’ve been researching this for some time. I now believe it is some sort of synchronization thrashing problem. This worked for me:

Log out of your Apple account.

Log back in.

I chose to “remove” data like contacts, etc. which is an option when logging out of your Apple account.

Another poster elected to keep local data and then did a “merge” when he logged back in Which worked for him.

I also reset my network settings but I’m not sure this was necessary.

Same here. My XR is draining quickly! The phone also has great difficulty charging . I have tried many fixes, outlets, charging devices etc. I am actually picking up a new phone today but if it is the software problem I am afraid I will have the same issue. My husband has had a Samsung for about 6 years. Not one problem! If this dies not get resolved immediately I will switch product to a Samsung. Apple is going down in their quality. Last issue was the big battery fraud! Now this? Really Apple you should be all over this considering your recent history!!!

I am also having this problem. Iphone 7 was absolutely fine until latest update. If I don't use it it's fine, but as soon as I start using it I can see the battery charge dropping. I've turned off nearly everything that runs in the background and it's still draining. Some days I am having to recharge it twice!

In the last 4-5 days my 2 iPhones and 2 iPads are losing their charge rapidly. The battery usage shows Siri as using 70% of the battery. I have turned Siri off on all the devices and two days later it still shows a Siri as the problem. The iPhone also hears up even when turned off. Help!

I’ve been experiencing the same problem. I haven’t had any issues with my battery until now. Now, my battery drains so quickly. I’ve had to start bringing a charger with me when I’m out and I haven’t had to do that before.

Not sure what is going with apple lately. But i just updated my iphone 7 plus to 13.5.1 and after that it the whole battery scenario start. My phone will literally shut down on it’s own even when my battery is at 80%, which has been happening for the past week. I don’t really write complaints but this product that i spend my money on is getting ridiculous. My wife has an iPhone 6 and battery is perfect no issues at all and she never update. So with that being said, i wish I did not update at all. Apple please fix this crap, you know how annoying it is when your talking to someone and stupid phone just shuts off!!!! And don’t tell me to buy a new version if iPhone. Smh.

I have the same battery draining problem with the iOS 13.5.1. The battery has an 87% health rating. I've changed no settings since the update and rarely touch my phone -- nothing is open -- and still the battery drains away, even when I've set it to low battery mode. Apple needs to fix this issue!

Apple Music is killing my 11 pro max. Music was running 20+ hours in the background and the device would get hot. Did all the things, but finally had to reset the device and restore from backup with the Music app deleted. Today after 4.5 hours of the same daily use, I have 83% battery life left. If there's no fix soon, my apple music subscription will be no more.

I dropped my phone and had to send it in to have the glass repaired. Apple upgraded the iOS without my consent and now my wonderful phone has the overheating and battery drain issue. CLEARLY its the iOS. and I cant down grade because my iCloud backup choices are limited to very recent with the issue, or my xs. So I cant downgrade. I hate Apple

I have commented about my iphone battery issue last week. Well it got worse, now my iphone won't even turn on. And with this pandemic all Iphone store are close, which is a pain. Only if they did not have this update my phone would been perfect, now is ruining my life. Smart tech in apple please fix this issue,smh.

Last week this problem started for me. Battery overheats and is now unable to charge. I have tried everything and nothing helped. I re-installed my iPhone, I installed iOs 14 Beta (for some this might help) and also didn't help. I was in the Apple Store the other day and the genius told me it was not because of the iOs 13.5.1 that these problems occurred (...). So now, with no options left and no warranty, I am once again using my old iPhone. Considering to change to Android with pain in my heart.

Also, Apple would never admit it's the iOs update that's causing the problems. I think they were pretty rude with my on the phone, as well as in the Store.

Ive tried everything listed on this forum. I don’t use dark mode, battery doesn’t show apple music usage at all, i installed 14 Beta. Phone is still hot all because i broke my screen and Apple repaired it, upgraded my software and now i have the problem. i did not ask for an upgrade i had a cracked screen!!! thinking about going back to my 7 for a while

Same here. I have old phone and was fine until I allowed the ver 13.5 update. Batery is new and usage last all day until two weeks ago. Now phone starts and dies after a few hours and when phone reboots on chargeit will show as high as 40% full and two minutes later its showing 27%. Had it plugged up today and was showing it charging and the battery % going down not up. No problems until update. Not buying a new phone. FIx it! Can't be on conference call two 10 minutes off charger and dead in 15 minutes. Just silly Apple isnt going to force a new phone to me. If so I'll switch name brands its been fine. I dont need updates on old phone. I was happy! Get me back to real battery life.

This is my third time complaining about this idiot update. Having my phone being shut off automatically even its at 80% is very, very, very frustrating specially when your on a conference call or an important one. Is getting to the point where I want to throw it out the window, and I’m sure apple will love that so I can buy a new one. Freaking fix this stupid update because I’m 100% sure I’m not the only who is frustrated.

With an upgrade, the use of your iPhone is supposed to improve, not degrade.

Taking all these measures by SravanKrA, which are straightforward to conserve battery power are ridiculous if before the UPgrade [sic] there were no such problems as I have now.

It's not the iPhone settings I have to change to get a workable iPhone, it is Apple that has to address this ridiculous downgrade to 13.5.1

Besides....it took 25 minutes to download the 'upgrade' to my MacBook Pro (and I have a lightening fast internet connection) which with iTunes gone you cannot even follow the progress, and it took 12 minutes for my iPhone XR to install 13.5.1.

I wish I never did this downgrade to 13.5.1

A furious customer......!!!
