IPhone 12 suddenly heats up

Is it just me or iPhone 12 suddenly heats up? To add note: I never use my phone when charging, and usually when I experience this is when I’m just scrolling through Facebook.

This only happens to me when charging and using my phone at the same time

I assume your battery is also getting consumed faster during this time. Try to see from battery usage which app is consuming more in that case. Which iOS version are you on?

Thank you. I'm on 14.6

I've had this phone since April, but I hadn’t experienced anything like this, not until I updated my software

I did read about user comments from an apple forum that after the iOS 14.6 update, hearing issues were occurring a lot, and they suspected the mail app to be the culprit.

ohhhh I see. Thanks so much. I do hope on the next update that everything will get back to normal.

Really? Wow. I have the 2020 SE and I use a lighting to USB-C charger to charge my phone. But I use a 60W 3rd party adaptor because it can handle both fast charging my phone and properly charging my iPad at the same time.

That being said, I've NEVER had charging or heating issues EVER with my iPhones, and I've never used the default chargers.

But since the 14.6 update, I'm now feeling my phone get pretty warm. And it has an Otter box case on it. I normally don't feel any kind of heat whatsoever with the case.

So I've since been charging it off because I never felt heat before. And it scared me. I just got my phone less than 2 months ago. Granted, I have Apple Care and the phone is paid off, but still.

So thank you for mentioning that this seems to be a recurring thing. I'm hoping it gets fixed soon because there is absolutely no reason for me to have to go exchange my phone.

But I'm curious as to why the mail app would be the culprit 🤔?

Meantime. Try to turn off push to fetch new data and change fetch to the required time you like, or keep it manual.

Usually if you use a fast charger the phone would generally heat only if the charging starts from an Avery low percentage like 1% and up to 60%. After that, it slows down. But if you charge from a much higher value like 20% or above, then the heat generation would be quite less. I cannot absolutely say the is the issue. But I did see people mentioning this issue in a few forums. You can try something I mentioned to Yiddah above regarding mail app and see if it helps. This is why I was afraid to upgrade from iOS 14.5 to 14.6. I'm still on the former. There is no sure way to see in real time like in Mac as ther is no task manager/activity monitor to see, at least without some third party apps I guess.

When I searched, I see that it is currently off. Thanks for the tip

It’s because of the weather, i guess
