Ways to Fix iPhone Heating Issues Post iOS 16/17 Update

Part 1: Why Does My iPhone Heat Up after iOS 16/17/18/26 Update?

iPhones, being advanced devices with powerful processors and multitasking capabilities, can naturally warm up during use. However, if your iPhone starts heating up after installing iOS 16 to iOS 26, there may be deeper issues at play. Below are some of the most common reasons behind iPhone heating issues following a system update.

• Environmental Factors

Exposure to direct sunlight, high temperatures, or humid environments can trigger iPhone keeping hot. Leaving your device in such conditions may not only cause it to overheat but also risk damaging internal components, leading to persistent performance problems.

• Intense Usage

Working with several high-power applications simultaneously can also cause iOS 16 overheating. Long gaming sessions, high brightness, live wallpapers, multiple background apps, high resolution and frame rate of the device's camera, etc., are some common examples of high power usage.

• Operating System and Application Bugs

You may also feel your iPhone warm due to the presence of bugs in the installed update. In addition, there may otherwise be some apps on the device that are not compatible with iOS 16/17/18/26. Such apps can strain the device's processor, causing it to get heated up.

• Your Device Cover

Your iPhone’s outer casing helps dissipate heat and keep the device cool. However, using heat-trapping accessories like thick rubber or silicone cases can block this process, leading to iPhone heating issues during regular use.

• Faulty Components

A defect in the device components can also make the iPhone feel hot. If the heat comes from the rear side of your device, a faulty battery may be the culprit. The front and bottom heating issues indicate a fault in the processor and charging port respectively.

Part 2: Effective Solutions to Fix iPhone Overheating After iOS 16/17/18/26 Update

If your iPhone keeps getting hot after the iOS update, here are some quick and easy ways to get rid of the issue:

Fix 1: Put in a Shady Location

To prevent iPhone heating issues caused by environmental factors, avoid exposing your device to direct sunlight or hot areas. Instead, keep it in shaded or air-conditioned spaces. However, never place your iPhone in extreme cold—like a freezer—as sudden temperature shifts can cause further internal damage.

Fix 2: Don't Use Your iPhone Consistently

Intense usage can also make your iPhone hot beyond the normal limits. If you notice extra heat, try giving your device a break. Leave the iPhone idle for some time in a cool and dry place. This should hopefully bring down the temperature of your device. If you still need to use the device, it would be better to lower the screen brightness. Closing the multiple apps running in the background is another wise step.

Fix 3: Say NO to Charging

When aiming to bring down the iPhone heat, you should not put the device on charging. Instead, put the device on idle mode in a cool place and wait for the heat to get dissipated. If your iPhone gets hot during the charging process, consider unplugging the device for some time. You should understand that charging the device generates extra heat. This can make things worse for the already hot iPhone.

Fix 4: Remove Your iPhone Case

As already stated, the outer covering of your iPhone is responsible for keeping the processor cool by dissipating the heat away. Putting the device inside a cover insulates the latter's backside and the processor heat gets trapped. This results in your iPhone getting overheated. Take your device out of the cover on encountering more than normal temperatures. The trapped heat will be released to cool down the iPhone.

Fix 5: Force Close Unused Apps

Closing unnecessary apps can reduce the load on your iPhone processor to eliminate the overheating issue.

• Double-click on the 'Home' button to display the open applications.
• Swipe up to the 'App Preview' option.
• Drag left and right to view the running applications and tap the 'Close All' option.

Fix 6: Restart Your Device

Sometimes a trivial issue in software operation can also make your iPhone too hot. Such concerns can be sorted out by restarting the device. To proceed with the process, take the following steps:

• Press and instantly release the 'Volume Up' button.
• Press and instantly release the 'Volume Down' button.
• Press and hold the 'Power' button till the 'Apple' logo appears.

Fix 7: Reduce the Processor Load

Reducing the device's processor load is a smart idea to combat the iPhone heating annoyance. You can try the following options:

• Refresh the background apps by toggling the 'Turn Off' option for selected applications or applying a total 'Off' for all apps. This will also increase your device's battery life. You can take the following path using the facility:

Settings>General>Background App Refresh

• Turn off the 'Share My Location' service and prefer a setting of "Never" or "While Using" instead of "Always On". Then, take the following path to change the location settings:

Settings>Privacy>Location Services

• Turn off notifications from selected or all apps on your iPhone. This setting will also save enough battery. Then, take the following path to modify the notification settings:

Settings>Notifications

• You can also use the low power mode and turn on auto brightness to reduce the heating effect. Turning off wireless connectivity, such as Bluetooth, GPS, Wi-Fi, etc., and switching on 'Airplane' mode can also help to bring down the device's temperature.
