My iPhone SE 2020 is lagging and overheating after updating to iOS 17.4

Devices normally do get warm after an OS upgrade. This is due to some optimization and re-indexing that is happening in the background. Your iPhone SE 2020's processor should be fine - best if you can let it do this and not play games, stream or watch videos, to speed up the optimization process.

If your iPhone 'overheats' after 72 hours, then maybe it is time you bring it in for an inspection by Apple's support people.

I use my iPhone XR daily. Recently i upgraded to iOS 17.4 and my phone had been dying quicker and over heating and I don’t know what to do I wish I just stayed on ios 17.3

After updating to IOS17.4 , the next day my iphone 12 went dead ... Iplanet says its a harware issue... bought around 16 months back, its totally unacceptable to quote 39000 to fix it...

I am having issue in iphone 12 pro max after 17.4 my battery health going down 89% from 95%

After updating my iPhone 12 to iOS 17.4, I am no longer able to get a live location for my daughter in the "Find My" app. I hope that this is being worked on.
