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.

Both battery drain and cannot connect to Bluetooth for use in car. Doesn’t appear to be a solution. Very annoying and makes me angry.

My iphone11 doesn’t charge. I’ll have it on charge for half hour and it doesn’t move.

SE will no longer charge after installing IOS 13.5.1 overnight and to make matters worse the battery is being drained at a much faster rate than normal. Can’t find a fix anywhere

Terrible battery drain even if all backgroud services etc. disabled. The Apple SW goes worst and worst, too comlicated already. Unfortunately. A simple reliable alternative is needed.

Been talking with Apple tech support on two long chat sessions and they gave up. Since installing iOS 13.5.1, my phone crashes multiple times daily. When it crashes then restarts, battery power is 9% or lower. Just before crash battery power typically 80% or greater. If I reboot twice in a row, battery power will go back to 80% plus then typically crash a few minutes later. Crashes sometimes occur when I start an app but sometimes when I’m in the middle of using the phone, as a phone. Phone also intermittently runs hot. Phone has been wiped clean twice… Read more »
