Iphone 13 pro overheating

So I just got off with Apple support and this helped me out. They had me go to general and then background app refresh and turn it all off. Lots of social media apps run in the background while you’re not using the phone. I surprisingly had over 24 hours of apps in the background. Also go to your battery section scroll down to battery usage by app and click the show activity tab. That’s where you can see how many apps still run in your background causing the phone to overheat. My top 5 like I stated earlier were running for more than 24 hours. Once I turned off all the background app refresh it’s been working fine so far, I’ll update if it changes but usually by now I would start feeling some heat. Also don’t just click background app refresh off. You have to actually click the tabs of each app to turn them off. Cause even though I had most of them off, some were on even when the whole section was tabbed off at the top

Just to update this. It was the Bluetooth causing it to overheat and drain the battery much faster than normal. After turning off the Bluetooth and allowing it to cool down, it's now cool to the touch even though I'm still running the hotspot and the battery is draining much slower now. Before the battery life meter showed a discharge rate on the scale at a 45-degree downslope but now it's almost a level discharge on the scale. It's been eight hours since recharging to 100% and I'm only at 65% on the battery with using it as a hotspot all day surfing the internet and streaming videos.

So, I consider this problem solved and may be a problem with others running their Bluetooth antenna like it was for me. I'm just so glad I'm not going to do a factory reset because that would be an all day event getting everything set back up and reinstalled the way I had it plus syncing my iTunes library would take another eight hours or more.

I solved my overheating problem by turning off all the apps running in the background, with calendar being the main culprit of running continuously until draining the battery.

Go into settings and change the mail, calendar, and other apps to manual instead of fetch or push notifications. After doing this my phone doesn't overheat anymore and I only have to recharge once a day and I use it as a hotspot all day long. With all these background functions turned off, the phone doesn't get hot despite being used as a hotspot all day long surfing the internet and watching YouTube videos and livestreams.

Bluetooth is also a huge power drain and if you're not using a Bluetooth peripheral make sure this is turned off also.

When your phone is properly configured you won't have these overheating and power drain issues even on 5G which is what I have.

This problem started up again and it was the calendar and other apps running in the background so I went into settings and changed everything to manual update for the calendars, e-mail, and turned off most of the apps that had running in the background checked.

Now the phone is back to normal barely gets warm when charging and only needs to be charged once a day while being used as a hotspot instead of several times a day.

Checkout those background apps, especially calendar, turn them off or change to manual update like I did and you should see an immediate difference with how your phone behaves.

In the period of 16.1.1, I also suffered excessive heat ‘points’ (meaning, my phone was excessively hot in certain areas of the phone); my battery deteriorated by 2%, from 100% full charge to 98%. I updated to 16.1.2, where it now no longer over-heats nor do I have battery-drain (I hope this lasts this way); my iPhone 13 Pro Max runs for nearly 2 days, BUT, I still have to have SIRI off, completely, AND, all my APPs I have all ‘background’ updates ‘OFF’ (I say all this, for 15.0 I had all settings ‘active-ON’ and my phone lasted over 2 days, where I was on the phone and internet for over 9 hours). Before you update, make sure you remove all APPs, then allow 24hours, then using a private network and your phone connected to a charger update, leave the phone ‘on’ from 9pm to 8am (there are peak times of background activities, I say this only because when looking at the battery chart it showed background activities) then individually re-install your APPs. This was the procedure had to do, like the old days with computers.

Hey ilyangski,

Thank you for using the Apple Support Communities! We understand your iPhone 13 Pro appears to be getting warmer than expected. We'd like to help.

Based on the description of it getting warmer than expected when transferring files and while connected to the charger, those can be expected reasons why the device would feel warmer. If you're performing intense tasks, it will feel warmer too. There are several more reasons where the phone getting warmer than expected are considered normal. Check out this article please: Keeping iPhone, iPad, and iPod touch within acceptable operating temperatures

"When you use the device or charge the battery, the device might get warm. You might notice that your device feels warmer in these situations:

• When you set up your device the first time
• When you restore from a backup
• When apps reindex or reanalyze data, like Photos tagging for faces, places, or keywords after a software update
• When you use graphics-intensive or augmented-reality apps or features

These conditions are normal, and your device will return to a regular temperature when complete.

Here are some of the higher ambient-temperature conditions and activities that might cause the device to change performance and behavior:

• Leaving the device in a car on a hot day.
• Leaving the device in direct sunlight for an extended period of time.
• Using certain features in hot conditions or direct sunlight for an extended period of time, such as GPS tracking or navigation in a car, playing a graphics-intensive game, or using augmented-reality apps."

We also invite you to review the section in that article titled 'If your device gets too warm' and 'If you see a temperature warning screen'.

Best regards.

It is normal for any electronic device to get warm when being charged or discharged. The iPhone has built in over-temperature protection, and will shut down if it’s temperature exceeds safe limits. If this doesn’t happen the phone is not overheating.

This heating effect is called the Second Law of Thermodynamics. Anything that creates or uses energy does so with some loss. That lost energy is expressed as heat. So when you charge the phone it generates heat in the power source, heat in the charger circuit in the phone, and heat as the energy goes into the battery. The faster the charging, the more heat is generated. Likewise when you discharge the battery; not all of the energy from the battery gets to the circuits that use it. Some of it becomes heat. If you use the cellular network for voice or data, converting energy to radio frequency signals is very wasteful; only about 30% of the energy that goes into the network components comes out as radio signals, which means that 70% of the energy from the battery is wasted heat.

If you fast charge it will get hot. But to repeat: The phone monitors its temperature continuously, and iIt will shut down if it gets too hot. So if it doesn’t shut down then the warmth you feel won’t hurt it. It gets hot because fast charging and interactive gaming uses a lot of energy.

Sounds like your problem may be an update related problem that was fixed shortly after you posted this. You may want to check your calendar settings as well and change to manual instead of fetch or push. The calendar, Bluetooth, and background apps was my problem. After turning them off or changing to manual, the phone started working fine again without overheating or rapid battery drain.

Tell the rep that you want to return the phone, then get a new one. Usually they will understand. It would be a good idea to make an appointment, and to verify the store of choice is open, as Apple has closed some stores in high-COVID areas: https://apple.com/retail

This is 100% correct I have had this phone for over two months now in which one month I used 5G and the other month I used LTE when on LTE the phone rarely if ever dimmed or got hot if it did it was because it was on the charger but while connected to 5g I always had screen dimming this phone is 5g Capable yes but I wouldn’t recommend it if you have 5g signal you should still have LTE and that is fast enough

The explanation is that something is using energy. That’s why it gets hot. If you have a 5G connection that is why it gets hot. 5G uses much more energy than LTE. And the spot it gets hot is where the hardware circuit is that is using the most energy, probably the 5G chip. And if you read the “science” it explains why it gets hot when the phone is in use also, and not just when charging. Discharging also uses energy, and does so with less than 100% efficiency. The difference is heat.

It doesn’t matter what you WANT. You agreed to Apple’s terms when you bought your phone, which says they can replace the phone with new or refurbished at their option. However, if you bought it directly from Apple they have a 2 week return for any reason policy, so you can return the phone, then buy a new one. Actually, they will usually treat it as an exchange for a new one in an Apple store if you are within the 14 day return window. Further, with the holiday season, they have extended the return period for any device purchased after November 1 to January 8, 2022.

Do you use Bluetooth? That will cause it to overheat also regardless if your earbuds are on or not, as long as Bluetooth is turned on, it will drain the battery and cause the phone to heat up. Check your calendar also and change it to manual instead of fetch or push notifications. I use my phone all day long as a hotspot on 5G and it doesn't overheat anymore after turning all these background activities off.

My iPhone 13 Pro has same issues, though some things to do to minimize how often this happens:

1. Make sure that background app refresh (settings) is completely off. I don’t think most people have a valid reason why that needs to be on.
2. Keep Bluetooth turned off until you have an active need for it

Although the above two steps have certainly helped, the phone will still get hot at times for unexplained reasons. One particular situation is when I am using the Mint app (personal finance management). Every single time without fail when I use the Mint app the phone will get hot. I understand that the app might be resource intensive due to fetching financial data from multiple sources but I don’t think that justifies the phone getting so hot.
