iOS 13.5.1 issues: Battery drain, Bluetooth problems, and more

Apple recently released the latest iOS 13.5.1 update. The update is available to users of all compatible iPhone Models. Unlike the previous update, this one doesn’t bring any new features but instead focuses on improving the overall security of the OS.

Although Apple’s update release notes aren’t very clear on what exactly the new update does, it does state that the update addresses the vulnerability exploited by the uncover jailbreak. With that being said, most jailbreakers would want to avoid this update. The rest of the users can comfortably install this release, and they won’t notice any difference in the way their iPhone works.

Or will they?

Although the new update brings zero new features, it actually causes some problems to users who installed it. Users are reporting battery drains, Bluetooth issues, connectivity problems, and more.

However, none of the problems seems to be widespread, as these are the individually reported cases. You have better chances of installing the update without any problems, than being stuck with an annoying issue. Nevertheless, I’m going to list some of the reported problems here, so you can see what could potentially go wrong.

iOS 13.5.1 battery drain

Reports about the battery drain caused by iOS 13.5.1 have been circulating on Twitter since the update’s release. Here’s one of the complaints:

Right now, the solution to this problem is unknown. It appears that users experiencing the battery drain issue will have to wait for Apple to release a follow-up update.

iOS 13.5.1 Bluetooth issues

Although reported by the smaller number of users, it appears that Bluetooth also doesn’t work for some people who installed iOS 13.5.1.

iOS 13.5.1 Face ID issues

Although iOS 13.5 improved Face ID to make it work with face masks, some people apparently have problems with it stretching to iOS 13.5.1.


Other problems

Besides the above-mentioned issues that appear to be more common, there are also a few more problems, including a camera problem, weird charging (though this one wasn’t specified, so I can’t tell you whether it was indeed caused by iOS 13.5.1, and a SIM card issue where the phone shows SIM cards as invalid.

Unfortunately, there are no confirmed solutions to any of these problems. Apple support usually recommends generic solutions to particular problems, by I doubt any of those will be helpful. Users that were hit by the update will probably have to wait for a patch.

I used to charge my phone once a night, right before bed. I’m now having to plug in my phone three to four times a day after using my phone for things that aren’t taking up a lot of resources at all. On top of that, my phone has been getting hot to the touch while doing things like scrolling through the internet. My iPhone 11 used to have insane battery life , and this is frustrating.

i have huge battery drain now on 13.5.1. Have to charge twice a day minimum, and sometimes 3 times if I use my phone in just a normal way.

My ipone SE will connect to bluetooth devices however they do no show up on the connected devices list. And it appears that it continues to search for them.
I tried all the fixes showing up on the various web pages, but none fix the problem.

I have iPhone XR, running iOS 13.5.1. Since downloading this update, my battery drain is horrible! My screen is also going dark; not green, even though I have Brightness turned up to around 78%. Is Apple working on, or ignoring the widely reported battery drain issue; if not, why??? This is a terrible update! Is there any way to uninstall the update, or are we stuck with it, and have to be tethered a charger all day?

My IPhone 6s Recently within the past two days has been overheating like crazy. I have checked they my phone and is in perfect condition with no viruses or bugs, but I found out that a lot of people are experiencing the same problem as me. I’m beginning to think it is because of the IOS 13.5.1 update due to the fact I installed it late and the problems have recently started coming in. The back of my phone around the camera area is so hot I’m afraid it might actually be burning the inner parts of the phone. It’s… Read more »

Mine is exactly the same since it updated to 13.5.1 🙁

My iPhone 7 max is is also unusable after this update to 13.5.1for the same reasons massive overheating and battery drain.
When is Apple going to take responsibility and fix this.
If they don’t do it soon I’m going to have to lose all my data and reset my phone back to a previous iOS. Otherwise I’m walking around with a $1000 piece of junk in my bag that doesn’t even have the battery power to last a single call
Shame on Apple.

My iPhone 7 is possessed. It fully charges overnight…is 100% when I get up. I unplug it and within just a few minutes, it goes down to like 12% and then shuts down on it’s own. Yesterday, it shut down multiple times randomly. I wasn’t even using it. My phone normally holds a pretty good charge, so I’m guessing this is a new issue that came with the last update. I have experienced it several times over the past few weeks but can’t seem to find any consistency to test it with. I’m on iOS 13.5.1.

Ugh, this is such garbage! Does anyone know how to fix this or go to an older operating system for their iphone? I have a 5SE and was working perfectly fine on Friday, now it is overheating and battery drain, and apps aren’t working. When is the next update?
Any solutions/suggestions would be much appreciated!
