Why is My iPhone So Hot After Update IOS15?

1, Install the Latest iOS 15 Software 

The iPhone getting hot in iOS 15 may be cause by the wrong version released by Apple. Just download the latest iOS 15 software
Settings> General> Software Update and download the latest iOS 15

2, Update App

Some uncompleted software may also cause the phone to heat up
App Store> Today> Your profile> Update all.

3, Disable Location Services

Using location services can have a significant impact on battery life. Settings> Privacy> Location Services.
If you have disabled the location services you need, don’t worry, it will prompt you whether to enable access to location services when you start it.

4, Disable Background Application Refresh

Although Apple has made many optimizations to ensure that battery consumption is kept to a minimum, developing and using bad applications can also cause your iPhone to heat up.

"Settings"> "General"> "Background App Refresh" and turn it off to close applications such as Facebook or other applications that do not need to be updated all the time.

I strongly recommend turning it off for the Facebook application, it will cause the iPhone to heat up.

Use Dark Mode

In 2013, Apple integrated a system-wide dark mode in iOS 13. It extends from the live wallpaper to the widget screen, and then to the settings screen and applications that add dark mode support. It should help improve the battery life of iPhone 11 Pro, iPhone XS, iPhone XS Max and iPhone X equipped with OLED displays. Just go to the control center, press the brightness slider, and click the appearance button to switch between light and dark modes.

Go to Settings -> Display and Brightness, and turn on the automatic option. Then click Settings to switch to a custom schedule. By default, dark mode will automatically turn on after sunset.

Use Low Power Mode

You can do this by going to "Settings"> "Battery" and enable low power mode. The low-power mode temporarily reduces power consumption by turning off or reducing email acquisition, background application refresh, automatic downloading, and some visual effects. Apple said that the low-power mode mode can extend battery life by another 3 hours.

When your remaining battery power reaches 20%, you will receive a prompt to enable low battery mode and automatically disable it when the remaining battery power exceeds 80%.

General Tips

The tips under the section will highlight areas where you can disable content that doesn’t apply to you so you can prevent your iPhone from getting hot.

i. Widgets

Remove some unnecessary widgets, as some of them may be using location services and drain battery life

ii. Turn Off Dynamic Wallpapers

Dynamic wallpapers bring subtle animation effects to home and lock screens. But animation will take up CPU cycles and consume more battery. Go to "Settings"> "Wallpaper"> "Select Wallpaper", where you can go to "Still" or set the image in the photo library as wallpaper.

iii. Disable Motion Effects, Parallax

iOS provides many animations and physics-based effects for the interface to help users understand the layered elements in the UI. Some of these effects may even access gyroscope data, which will further cause battery consumption. You can disable these exercise effects by going to "Settings"> "Accessibility"> "Sports"> "Reduce Exercise" and turning on the switch.

iv. Other Tips

1). If you hardly use Bluetooth, turn it off (Settings -> General -> Bluetooth) to set an automatic lock interval so that your iPhone will turn off more quickly after a period of inactivity.
2). To set the auto-lock interval, navigate to Settings> Display & Brightness> Auto-lock and set the auto-lock interval to 30 seconds, 1, 2, 3, 4, or 5 minutes.
3). You may know that using Wi-Fi will drain the battery of your iPhone. To disable this feature, please launch the "Settings" application, click Wi-Fi, and then click the "On/Off" switch of "Ask to join the network" to disable it
4). Dimming the screen helps to extend battery life. You can lower the default screen brightness, or turn on auto brightness to allow the screen to adjust its brightness according to the current lighting conditions. Launch the Settings app, scroll down and tap Brightness and Wallpaper, then set Auto Brightness to On.
