1, clean up the running memory and storage space.

Use "one-click acceleration" to clean up background applications, use I housekeeper to clean up the storage space of mobile phones in time, uninstall uncommon software, and keep the remaining storage space above 20%.

2. Check whether the mobile phone is hot or used when charging.

When the mobile phone has a serious fever, its performance drops and it gets stuck. It is suggested to avoid using mobile phones when charging, reduce the brightness of the screen appropriately, and turn off applications and functions that are not used or consume abnormal power, such as Bluetooth and NFC.

3. Check the power saving mode and power supply.

In the case of power saving mode/low power mode or low power, the device will reduce some performance to save power. You can switch to normal mode for observation, and keep sufficient power (above 20%).

4. The networking application switches to a good network.

When the network is unstable, the software will load slowly. Please try to change to a good network.

5. Upgrade the system and software to the latest version.

The new version has improved compatibility and stability. You can try to upgrade your system and upgrade to the latest version of the software.

6. Uninstall and reinstall the software

Unloading and reloading software can improve the software jam caused by abnormal data. Please back up the important data of the software, uninstall the software, and then go to the app store to reinstall the software.

7. Uninstall the third-party mobile phone housekeeper software.

The mobile phone has built-in I housekeeper software, which has better compatibility. If third-party mobile phone management software is installed, please uninstall such applications and try again.

8. Check accessibility.

If the barrier-free function is turned on, it will increase the system load and lead to performance degradation. It is recommended to enter Settings-Quick Assist-Accessibility, and turn off unnecessary functions in time.

9, restart the phone

Try to restart the phone. Restarting can effectively clean up the cache and alleviate the jam phenomenon.

10, reset the phone.

If necessary, you can select "Clear All Data", reset the phone and try again (this operation will delete all data, including software, SMS, contacts, notes, etc. ). Please back up the mobile phone data in advance when operating.
