Fix: ProMotion lag issue on iPhone 15 Pro

The iPhone 15 Pro and Pro Max have one of the best processors around. Additionally, the iPhone 15 Pro boasts a ProMotion display that supports a 120Hz refresh rate. However, even with class-leading hardware, issues like the iPhone 15 Pro’s ProMotion lag can still occur.

Unless you’re replacing your iPhone 15 Pro’s ProMotion display, there are many possible workarounds. In this article, we will consider how to fix ProMotion lag issue on iPhone 15 Pro.

1. Force restart your iPhone

Although it doesn’t happen often, apps may freeze on your phone. If this happens, you won’t be able to switch between apps, and you’ll feel stuck.

1. Press and release the volume up button.
2. Press and release the Volume Down button.
3. Press and hold the side button until you see the Apple logo.
4. Release the side button.

3. Try clearing storage

Sometimes you have a lot of apps on your iPhone that you don’t use, or you might want to use the web version instead. Fortunately, Apple iPhone has a feature called “Unused Apps Offload” that solves this. But it’s not just an app issue. You should also consider how much space your photos and other things will take up. We recommend that you always keep at least 25% of your storage space available to ensure your phone performs at its best.

1. Launch settings from the home screen
2. Scroll down and tap General
3. Select iPhone storage
4. If your device is the 256 GB version, make sure you have at least 20-25 GB free storage

4. Move your iPhone to the desired temperature

We recommend using your iPhone in an area that’s neither too cold nor too hot. Apple recommends keeping it between 0 and 35 °C (32 and 95 °F) for optimal performance. But sometimes the weather doesn’t cooperate. If your device is having problems due to temperature, try moving it to a room with a more comfortable temperature.

5. Close apps that are causing promotional lag on iPhone 15 Pro

If your screen freezes while using an app like Instagram, your best bet is to close the app and reopen it.

1. Swipe up from the bottom of the screen
2. Swipe right or left to find apps
3. Swipe up on the app preview card to close it

6. Reset all iPhone settings

This is an iPhone process that restores all settings to default without erasing personal data such as photos, music, contacts, etc.

1. Open settings
2. Tap “General”
3. Scroll down and tap Transfer or Reset iPhone
4. Select reset
5. Select “Reset all settings”
6. Please enter your passcode for confirmation
7. Tap Reset All Settings again to confirm

Note: Your iPhone will restart and your settings will be reset to default. Wi-Fi passwords, Bluetooth connections, and app settings will be lost.

7. Check the battery status of iPhone 15 Pro

iPhone battery health is unlikely to deteriorate within a year of use. However, if you constantly play graphics-intensive games, your battery may deteriorate faster.

1. Launch settings from home screen
2. Tap on battery
3. Select battery status and charging
4. Note the “%” next to the maximum capacity
5. If it’s over 95%, there’s no need to worry.
