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

Ever since updating to iOS 13.5.1, my phone's battery drain is ridiculous. Previously, from the time I removed my phone from the charger at 6:30 AM until I put it back on the charger at 11:00 PM, my battery would drain to around 80%. Now, it's at 80% by 8:30 AM. The device is also hot all the time. Clearly, something is wrong with this update, and it needs to be fixed.

iPhone 11

Hi Bella_1954

Sadly some updates do cause iPhones to work harder [generating heat], they usually settle down after a few recharge/restart cycles.

If you contact Apple Support they can diagnose any battery issues or whatever.

Turning off Push and changing to Fetch Manually helps [see SravanKrA's tips above] as well as turning off Background App Refresh.

Check Settings>Battery to see what is using the most power and adjust that app if you can. If you know an app using the most power is one you close properly then definitely do a Force Restart - this clears up any legacy issues that have carried over from before the update [if you left a lot of apps 'open' when you update, this can happen] -

Force Restart: In quick succession: Briefly press & release the Up Volume, then briefly press & release the Down Volume, then press and HOLD DOWN the Power Button, and keep it held as the screen shows the power off slider, still keeping the Power Button held while the screen goes dark and keep it held until the Apple logo appears, then release it. The phone will restart, hopefully a lot cleaner than before.

best of luck.

I've had the same issue - my iPhone SE (original) was at 98% a year ago, now it is 93% in less than one year. Same for my iPhone 7 except that it started on a lower maximum but it has still experienced a 5% loss of battery health - that's go to be a software issue. Also the 7 doesn't charge up very quickly and frequently gets incredibly hot, all this started with 13.4 but has continued and even gotten worse since the 13.5 updates

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

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.

I'm having exactly the same problem. I had this with an earlier update before, and Apple agreed there was a fault and replaced the handset. I'm frustrated that I will most likely have to go down the same route as before, which I shouldn't have to do.


Please could you advise if there is going to be a fix for this soon? It seems that after most updates there are complaints of battery drainage by a large number of people, and customers shouldn't have to experience this every time.

I'm tempted to ditch Apple and follow your advice to be honest. I got a new handset in March and it's dropped from 100% battery health to 97% in 3-4 weeks? It's ridiculous. I don't have the energy to go to my nearest shop (over an hour away) and get it sorted (took 2 trips last time before they finally admitted there was a problem). For it to be happening again now is just silly. A quick Google search of "IOS 13.5.1 battery drain" and it brings up so many results... I don't know how they get away with it

Very true! You can send off for a repair but then I think you have to pay a deposit for a crumby 5s or whatever they give you. It really is frustrating. The things they ask you to try including turn bluetooth off or turn off background app refresh... surely all of those things should be left on, work and be supported by the phone without any issue?! I literally spent all day in the Apple store last time I went because I wasn't leaving there until they sorted it! I'm having to use my phone a lot for work now of the current situation, as I'm sure a lot of others are too, so they really need to address it

This update did nothing for the end user. I did not change any settings or change any usage. My phone would go from 6am and still be charged to 60-70% after an entire day. Now it is down to 50% by the time I get to work at 9am. I have turned off all background apps, Wi-Fi and Bluetooth. Still not better and if I do use my phone it gets hot in my hand as well. What in blue blazes did y’all do????🤨 Thanks apple for screwing up yet again. Get your dang apples in a row and freaking test things out with actual users before releasing a massive screw up. Leave well enough alone. If it’s not broke don’t try to “fix” the freaking thing and make it better. Do your security update and such. But leave all the working things alone.


Does anyone know how to revert back to previous software version. That would be great knowledge for us everyday people to know and do until apple gets there poop in a group and this mess straightened out.


So get your software guys to work and fix what they broke, changed or made improvements to that make our phone “better”. News flash you didn’t make it better!!! I am due for an upgrade maybe time to convert over to Samsung.
