In this article, we will provide tips on how to fix battery heating up issue that users are facing on their iPhone running iOS 15. These tips have helped our readers in the past to fix iPhone that is getting hot.

Troubleshooting iPhone getting hot on iOS 15

Install the Latest iOS 15 Software Update

The iPhone getting hot in iOS 15 may be due to a buggy build released by Apple. Thankfully, Apple is quick to release bug fixes via a firmware update. Head over to the Settings menu and open General > software update and download the latest iOS 15 update.

Update apps

Launch the App Store and then navigate to Today > Your Profile > Update All.

Disable Location Services

When we install apps, they prompt us to give them access to various things such as location, etc., and we tend to blindly say yes. However, apps using location services can have a major impact on battery life. So you may want to review which apps should have access to your device’s precise location all the time. The best way to address this is to first tweak location services for all the apps. Launch the Settings app on your iPhone and go to Privacy > Location Services. You can either completely disable location services or even better, you can set ** ** so that an app will only use your device location when you open the app. This can be useful for apps like the App Store, which don’t need to be using location services all the time. You should also disable the Precise Location option that some apps may ask for. If you’ve accidentally disabled location services for an app that needs to use it, don’t worry, it will prompt you to give access to Location Services when you launch it.

Disable Background App Refresh

iOS includes smarter multi tasking that lets apps fetch content in the background. Although Apple has a lot of optimizations in place to ensure that battery consumption is minimal, it’s possible that a poorly developed app could be using this feature incorrectly which could cause your iPhone to heat up.

To disable Background App Refresh head over to SettingsGeneral > Background App Refresh and turn it off for apps like Facebook or other apps that don’t absolutely need to be updated all the time. Background App Refresh is a great feature for apps like OneDrive or Google Photos where you need to upload media in the background, but you don’t need it for every app. I would strongly recommend turning it off for the Facebook app as it is known to cause iPhone to heat up.

You have the option to enable Background App Refresh only when you’re on a Wi-Fi network. You could see if selecting just Wi-Fi reduces the battery drain on your iPhone or you may want to turn off completely. It will also help in saving mobile data on your iPhone.

Use Dark Mode

In 2013, Apple integrated a system-wide dark mode with the iOS 13 update. It stretches from the dynamic wallpaper to the widgets screen to the Setting screen and apps that have added support for Dark mode. It should help in improving battery life on iPhones with an OLED display like the iPhone 11 Pro, iPhone XS, iPhone XS Max, and iPhone X. Simply head over to the Control Center, press on the Brightness slider, and then tap on the Appearance button to switch between the Light and the Dark mode.

You can set the dark mode on a schedule as well. Go to Settings -> Display and Brightness and turn on the Automatic option. Then tap on Settings to switch to a custom schedule. By default, the dark mode will turn on automatically after sunset.

Use Low Power Mode

You can enable Low Power mode by going to Settings > Battery and tapping on the toggle. Low Power Mode temporarily reduces power consumption by turning off or reducing mail fetch, background app refresh, automatic downloads, and some visual effects. Apple states that the Low Power Mode mode can improve battery life by an additional 3 hours.

You will also get a prompt to enable Low Power Mode when you hit 20% battery remaining, and will automatically disable it when battery remaining crosses 80%.

General Tips

Please note that the tips under section are to highlight areas where you could disable things that are not applicable to you so you can prevent your iPhone from getting hot. We are not recommending or advising you to disable features just for battery life, as then there would be no point in using smartphones like the iPhone.

i. Widgets

You should review the widget list and remove the widgets that you don’t want to ensure they don’t consume battery life unnecessarily as some of them could be using Location services.

ii. Turn off Dynamic Wallpapers

Dynamic wallpapers  bring subtle animations to the home and the lock screen. Unfortunately, the animations take up CPU cycles and consume more battery. So if you have set a dynamic wallpaper, and you’re having battery issues, go to Settings > Wallpaper > Choose Wallpaper where you can go to either Stills or your set an image from your photo library as your wallpaper.

iii. Disable Motion effects, parallax

iOS comes with a number of animations and physics-based effects to the interface to help users understand the layered elements in the UI. Some of these effects even access gyroscopic data, which contributes further to the battery drain. You can disable these motion effects by going to Settings > Accessibility > Motion > Reduce Motion and turn on the switch. However, please note that enabling Reduce Motion will disable the effects in the Messages app.

iv. Other tips
If you hardly use Bluetooth then turn it off (Settings -> General -> Bluetooth ) Set Auto-Lock interval so that your iPhone will turn off more quickly after a period of inactivity. To set the Auto-Lock interval, navigate to Settings > Display & Brightness > Auto-Lock and set the auto-lock interval to either 30 seconds, 1, 2, 3, 4, or 5 minutes.
You’re probably aware that using Wi-Fi drains iPhone’s battery, but perhaps you didn’t know that one of the most intensive processes that iPhone’s Wi-Fi chip has to do is search for the available network. So if this happens at regular intervals, it’s going to have a noticeable impact on your battery. To disable this feature, launch the Settings app, tap on Wi-Fi, and tap on the On/Off toggle for Ask to Join Networks to disable it.
Dimming the screen helps to increase battery life. You can either lower the default screen brightness based on your preference or turn on Auto-Brightness to allow the screen to adjust its brightness based on current lighting conditions. Launch the Settings app, scroll down and tap on Brightness & Wallpaper, and set Auto-Brightness to On.
