Iphone battery draining after IOS update

Hi, I have an iphone 14, the battery started draining much faster than before i updated to IOS 17, my battery health is still above 90% so i‘m sure that’s not the problem. Before the update, my phone drained at about 6-8% per hour on wifi with youtube and about 15-18% on 5g. Now it drains at around 9-12% per hour on wifi and 18-25% on 5g. I have also noticed that on my apple watch se1, the battery drained at 4%/hr when i first got it and now it is at 7-8%, compared to 5-6% before i updated to watchos10. is anybody else experiencing this?

iPhone XS, iOS 15

It surely is not after iOS 17.4.1 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.

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.
