Battery drainage issue on iPhone and iPad after updating to iOS 18.5

It's been a while since iOS 18.5 came out and I've noticed a change in my battery life, it's definitely a lot shorter than previous versions. I've also noticed that when you change your icons to a certain color, the ones that sit in folders on the screen don't change and become pure black(iPhone and iPad). Are you having any similar issues with iOS 18.5?

Battery Health of 86% is starting to get low, and it would explain some of the issues you describe. You do not indicate what model of iPhone you have and how long you have had it. When the Battery Health gets to 80%, Apple will replace the battery. If the device is less than one year old at that point, it could be replaced under warranty, otherwise there will be a charge.

I have the exact same problem. Battery health is at 86% but in the past weeks (not sure if it is due to iOS 18.5), I notice that battery depletes super quick (2-3 charges a day) and also the charging speed is much slower now even when plugged in. Also, charging seems to be making the phone much warmer, causing charging to stop due to high temperatures even in a cool room when this never happened before.
