17.5.1 Drains Battery Fast and Heats Up

That’s kind of a ridiculous answer. It only heats up rather often after the 17.5.1 update. So how can anyone say it’s not the issue when it didn’t before???

I'm also facing this issue. I'm using iphone 13 pro and it is draining even when phone is idle (I'm not using it). Also it effects my battery health to 86% from 92% for no reason. This is completely **** from apple. Everybody is complaining but they are not fixing it.

Same issue here. Didn’t have it before update to 17.5.1

my phone gets pretty hot pretty quick and when. Need to charge it holds off on charging until it cools down

It surely is not after iOS 17.5.1 because...

I conducted a thorough search of this forum and uncovered numerous posts detailing similar issues across various iOS updates. This suggests that iOS updates may not consistently be the root cause. Below are a handful of examples extracted from the search results:

The links I've found suggest that the reason for battery drain may not be solely due to iOS updates, but rather, it could be influenced by how an iPhone is utilized.

• Yes, I've got into a pickle with this heat problem too. 13.3.1 was fine (for iOS13) but then came 13.5 and boom the heat started. From there I quickly went back to 13.4 and no joy. I then downloaded 13.5.1 and still no joy. When 13.6 arrived I jumped on it, what did I have to lose. After two days it started heating up again, bugger. It was then I thought I might as well jump on the iOS14 Beta program. The first beta was pretty bad but I waited and Beta 3 was better. We still had heat...

• Agree. Let’s create some new emojis and other trivial things over fixing the freezing and heating up issues caused by IOS13. I never had these issues on IOS12. I have advised Apple that my phone gets extremely hot causing me to remove from my person because it burns my skin. If it heats up to the point that something else occurs the look out. As I said I parted with my hard earned for this phone and to put up with this for several months. Please make rectifying this a priority other...

It's not always the iOS update's fault!  Many things can cause phone problems.  If you tell people you think it's an iOS update, it might make it harder to fix or find a solution for the real issue.

Remember, the right question often leads to the solution! Please look in the right direction.

iOS updates aim to enhance user experience, boost security, and fix bugs rather than disrupt core features. The majority of the issues after updates might stem from underlying, unmentioned factors. Updates won't typically alter personal data but may refine settings or features. Backup before major updates for safety. Review Apple's update details and backup advice for a smooth process.

Kindly consider checking your settings and addressing any device issues before attributing the issue to external factors. This could be a pure coincidence that the iOS update affected the iPhone functions.

Before initiating a standard iOS update, it's advisable to create a backup. Have you completed this step? If yes, proceed with the restoration from the backup.

Same. My phone starts to cook when I start scrolling though Instagram and Reddit.
