Alleviate HUAWEI phone/tablet lag

If lagging occurs shortly after a system update

• Cause: It is normal for your device to lag within a short period of time after the system is updated, as the system will optimize apps in the background for about one week, causing high load.
• Operation:
  1. After the update is complete, charge the device with the screen off for more than 2 hours.
  2. Observe for one week. After the system finishes the optimization, the lagging issue is usually automatically alleviated.

If the lagging does not occur after an update, perform the following steps to troubleshoot

A. Free up storage on your device

1. Clear background apps.
   • Cause: Too many apps running in the background will result in insufficient running memory and app stuttering.
   • Operation: Clear background apps regularly and power off and restart the device every two to three days.
2. Clean up storage space.
   • Cause: Insufficient memory can cause the system to run slowly.
   • Operation: Go to Settings > Storage to check and clear the storage space in a timely manner. (It is recommended that you reserve more than 20% of the storage space.)
3. Uninstall unused apps.
   • Cause: Downloading multiple apps may consume a large amount of memory.
   • Operation: Uninstall unused apps. To uninstall an app, touch and hold the app icon on the home screen to uninstall it.

B. Disable Power Saving mode and ensure that the battery level is above 20%

• Cause: If Power Saving mode is enabled or the battery level is low, your device will restrict its performance in order to extend the battery life.
• Operation: Go to Settings > Battery, disable Power Saving mode, and ensure that the battery level is above 20%.

C. Disable Magnification and Ignore repeated touches

D. Check whether the device is overheated

• Cause: Your device features an overheating protection mechanism that prevents it from getting too hot by reducing system performance.
• Operation: After the device cools down, check whether lagging is relieved.
  1. Avoid using the device when it is being charged.
  2. Lower the screen brightness.
  3. Disable apps and features that are not in use or consume excessive power, such as Bluetooth and NFC.

E. Check whether the device temperature is too low

• Cause: The battery activity is insufficient due to low temperature, which affects system performance.
• Operation: Avoid using the device in a low-temperature environment. After the device temperature rises, check whether lagging is alleviated.

F. Adjust the screen refresh rate to High

• Cause: When Screen refresh rate is set to Normal or Smart Resolution, the frame rate will be limited in some scenarios, causing frame freezing.
• Operation: Go to Settings > Display & brightness > Screen refresh rate (or Screen resolution) and set it to High for a smoother experience. (Skip this step if this option is not available on your device.)

G. Check your third-party apps

• Cause:
  1. Some third-party management apps may conflict with the built-in Phone Manager/Tablet Manager on your device, causing lagging.
  2. Some app servers are faulty, causing the device to lag when the apps are used.
• Operation:
  1. Uninstall the third-party management apps and try again.
  2. Provide feedback to the apps or call the Huawei customer service hotline for assistance.

H. Use a stable network

Cause: The network speed may be slow.

Operation: Go to Settings > Notifications & status bar > Status bar > Display network speed and check whether the network speed is normal in case of lag. If the network speed is slow, switch to another mobile data or Wi-Fi network and try again.

I. Update the system version to the latest

• Cause: System performance will be better in later versions.
• Operation: If your device has not been updated for a long time, update the system to the latest version.

If the issue persists

If the issue remains unresolved or you encounter any difficulties, please call the Huawei customer service hotline for assistance.
