I’ve heard from several readers who are concerned that the latest iOS release — iOS 16.5 — has turned their iPhones into portable pocket warmers.
And it’s not just a little bit warm.

These iPhones become physically hot to the touch and the battery depletes in a few hours with little to no usage.
And it seems pretty widespread, with a lot of chatter about it on social media and on Apple’s own support forum.
An overheating iPhone — or for that matter any device, especially if that device contains a rechargeable battery — is no joke. Prolonged high temperatures can cause glitches and crashes, damage internal components, drain the battery and permanently shorten the battery lifespan.
This is something you need to get on top of.

Several things can cause your iPhone to overheat. Here they are, along with things that you can do to mitigate these issues:
- These discounted Meta Ray-Ban smart glasses are my favorite Prime Day deal so far
- The smartwatch with the best battery I’ve tested is also one of the most affordable
- One of the best entry-level portable batteries I’ve tested is $100 off for October Prime Day
- Apple’s AirTag 4-Pack is $24 off at Best Buy ahead of October Prime Day
- Best early Prime Day monitor deals to shop in October 2024
Solution: Slow down on your iPhone usage.
Solution: Wait for the iPhone to finish its background tasks. If problems persist then it’s likely a bug in the update and the solution is going to have to come from Apple in the form of another update.
Solution: I’ve outlined how to look for and disable a malfunctioning app here.
Solution: Move to a spot with better signal. Choose lower resolution streaming options — for example, 1080HD as opposed to 4K — where possible.
Solution: Use a quality charger and cable. Switch to a lower-power charger. Remove the phone case if you use one. Use a wireless charger with built in cooling or avoid wireless charging.
Solution: Do your best to keep the iPhone within its operating temperatures of 0 to 35 degrees Celsius (32 to 95 degrees Fahrenheit).
Solution: Remove the iPhone from the case.
Solution: Get the battery serviced by Apple or a qualified third-party repairer.
One of the most rapid ways to cool down an iPhone is to turn it off completely and let it come down to normal temperature naturally. Don’t try to “speed up” the process by putting the iPhone into a refrigerator or ice box as this could also damage the battery.
