Is your iPhone hot to the touch or displaying an overheating alert after iOS 16 update? Do you frequently ask yourself, “Why is my iPhone so hot when I use it?”
If you’ve just downloaded and installed the iOS 16 update on your iPhone, then you may experience overheating problem. iOS updates are notorious in causing unwanted issues like overheating. The good news is that you can fix the iPhone heating up due to the iOS 16 update by following a few simple steps. In this article, I’ll walk you through 10 easy fixes for iPhone heating up after the iOS 16 update.
If your iPhone feels warm, especially after installing iOS 16 update, there’s no need to worry. However, if it’s often too hot to handle comfortably or if your iPhone displays an overheating alert, you should investigate the cause.
Why Does My iPhone Heat Up after iOS 16 Update?
We’ve established that it’s normal for your iPhone to generate enough heat to feel warm, but what could be the cause of your iOS 16 device getting too hot to use? Let’s take a look at some of the most common culprits. Some of these factors may cause excessive heat on their own, but often it’s a combination of several factors that leads to overheating.
1. Environmental Factors
This may seem a bit obvious, but environmental factors such as high outside temperatures and direct sunlight can cause an iOS 16 device to overheat. If you leave your iPhone out in the sun or a hot car, for example, there’s a good chance it’ll need to cool off before you can use it. Excessive moisture could also cause damage to a phone that causes it to get too hot.
2. Heavy Usage
Using your device in a way that demands a lot of power over a long period may cause your iOS 16 device to overheat. For example, long sessions of gaming or streaming can take a toll on your device. These activities require a lot of power from your central processing unit (CPU), graphics processing unit (GPU), screen and other components.
Continuous use of a top-quality video camera can also cause iOS 16 overheating problems, especially if you’ve selected a high resolution and frame rate. Even things like keeping your screen brightness on high, using animated wallpapers and having too many apps running in the background can require enough power to cause overheating issue on iOS 16.
3. Bugs in Apps and Operating Systems
Apps that have not been optimized to work with iOS 16 can also create heat-related issues. These apps can overuse your iPhone’s processor, causing it to generate excessive heat. The iOS 16 update could also have a bug that causes overheating. If you notice your iPhone heating up a lot after iOS 16 update, there could be a bug in the update that needs to be fixed.
4. Your Case
Your case probably isn’t the sole cause of the iOS 16 overheating issue, but it can contribute to it. Your iPhone’s exterior shell functions as a cooling surface that helps dissipate the heat your phone naturally generates. Some cases can trap heat and prevent your iPhone’s exterior from doing the work of cooling your device. Rubber cases are especially good at trapping heat. If you frequently wonder why your iOS 16 device is so hot, try using a different case or no case and see if that helps.
5. Defective Components
A defective battery, processor, charging port or another component could be the cause of the iOS 16 overheating issue.
If you feel heat coming from the back of the iPhone, it’s most likely the battery. If the heat is coming from the front of the iPhone, a processor may be at fault. If the bottom of your iPhone gets hot, and your iPhone is overheating while charging, it could be due to a faulty charging port or cable. Make sure you’re using a certified charging cable, and if that doesn’t fix the issue, you may need to repair your charging port.
A too-hot iOS 16 device is inconvenient because you have to wait for it to cool down before you can use it. iOS 16 overheating issue could also damage your iPhone, especially if it overheats frequently or reaches an extreme temperature.
Common Solutions to iPhone Heating Issue after iOS 16 Update
iOS 16 overheating issue may not be caused by a single reason, so you may have to try several methods at the same time. Note that some of these methods can only alleviate iOS 16 overheating issue, but not eradicate it completely.
1. Put Your iPhone in the Shade
Again, this point may seem obvious, but if your iOS 16 device is too hot, move it to a cooler location. If it’s outside, bring it into an air-conditioned building. If it’s in the sun, put it in the shade. This should solve the problem if the main issue was an environmental factor like high ambient temperature or direct sunlight.
However, do NOT put your iPhone in the fridge or freezer to cool it down. Excessively cold temperatures can damage your iPhone just as high temperatures can, and the quick change from too hot to too cold can cause even more damage. Placing your iPhone near a fan, though, should be okay.
2. Give Your iPhone a Break
One of the most effective ways to cool down your iOS 16 device, especially if heavy usage was the cause of the problem, is to reduce the strain on your iPhone. Simply stopping using the iPhone and setting it down someplace cool should be enough to allow it to simmer down. If your iPhone is hot, but you can still use it, closing down some apps and dimming your screen can help keep it from getting overly hot.
3. Don’t Charge Your iPhone
If your iOS 16 device is overheated, wait until it cools down to charge it. Charging your iPhone will cause it to generate additional heat, worsening the problem. If your iOS 16 device overheats while it’s charging, unplug it.
4. Remove Your iPhone Case
Removing your case may help your iOS 16 device cool down faster, as it will allow the iPhone’s exterior to dissipate heat more effectively.
5. Restart Your iPhone
If none of these other steps fixed the iOS 16 overheating issue, try restarting your iPhone. This should fix the issue if the cause was a minor software issue.
6. Reduce the Strain on Your iPhone
If you find that your iOS 16 device is overheating regularly, the reason may be that it’s frequently using too much power. Reducing the strain on your iPhone, at least every once in a while, can help prevent it from getting too hot. Try some of these things when you know you’ll be using your phone more heavily than usual. The power-saving steps you can take include:
- Turn off background app refresh: Some apps update in the background even when they’re not open. This is how they notify you when someone liked your Facebook picture or when you get a new email. Continually updating like this requires power. In your iPhone’s settings, you can turn off this function for certain apps to save yourself some energy.
- Close unused apps: Close apps when you’re not using them to prevent them from using up your battery and processing power.
- Dim your screen brightness: Keeping your screen on requires power and increases heat generation. Even reducing your screen brightness part way can save you some battery life.
- Use low power mode: If you notice your iOS 16 device starting to get warm, turn on Low Power Mode. These settings help reduce the amount of power your iPhone consumes and extends your battery life.
- Turn off Wi-Fi, GPS and Bluetooth: Turning off power-hungry features like Wi-Fi, GPS, Bluetooth and cellular signal search can help save battery life and keep your iOS 16 device cool. Consider turning these features off whenever you’re not actively using them.
- Turn on Airplane mode: Sometimes, a bad network connection can heat up your iOS 16 device while it’s searching for signal. It can happen in areas with poor network connectivity. Until you leave the area, you may want to switch to Airplane Mode to prevent battery drain and unnecessary heat generation. Of course, your iPhone’s functionality will be limited during this time, but it prevents your iPhone from shutting down entirely due to overheating.
7. Use Reputable Chargers
If your iPhone is overheating while charging, consider getting a new charging cable. Low-quality or incompatible chargers can cause charging problems that lead to iOS 16 overheating. To avoid these issues, use chargers that come directly from Apple or ones that come from a reputable third party.
8. Use Proper Charging Protocol
Are you using the right cable but still wondering why your iPhone gets hot while charging? In addition to the cable you use, the way you charge your phone can also help you prevent iOS 16 overheating. When you charge your iPhone, put it on a hard surface that doesn’t conduct heat. Charging your iPhone on a soft surface like a couch or bed is not ideal, as these surfaces will retain the heat your iPhone produces as it charges. Don’t worry about charging your iPhone overnight — this won’t cause it to overheat unless your iPhone has an underlying problem already.
9. Update iOS 16 and Apps
To get optimum performance, both the iOS and applications should be up-to-date.
Many app updates include bug fixes that can improve your phone’s efficiency, meaning they’ll use up less of your device’s energy.
To check for app updates: open the App Store and tap your profile icon. Under available updates section, tab update all.
If you are done with the app update, it is time to move your focus on updating the iOS 16. An outdated operating system can cause a lot of issues. And this could be one such issue that is making the entire system go haywire and heating the iOS 16 device￼.
So, if you think the iOS 16 device is still overheating, Give this one a try. It’s easy.
Navigate to the iPhone Settings and tap on General. Select Software Update.
If an update is available, tap on Download and Install.
10. Reset All Settings
Another tip to help fix ￼ iOS 16 overheating issue is to reset all settings. There is a possibility that the issue lies in the settings that you are not familiar with and hence, it would make sense to reset all of them. To do that, go to Settings > General > Transfer or Reset iPhone > Reset and then tap on Reset All Settings.
