Apple 6p gets stuck after upgrading ios 12.4.8.

1. Some system versions of Apple mobile phones have a frequency reduction mechanism. The specific experience is that when the power of the mobile phone is lower than a certain threshold, the frequency of the mobile phone will be reduced in order to maintain battery life. At this time, the running speed of our mobile phone will undoubtedly decrease. So we try to keep enough electricity.

2. Generally, the lack of memory in the mobile phone will also cause the jam. Generally speaking, just double-click the HOME button and close all running applications in the background, which will make your Apple phone smooth.

3. Clearing the cached data in the mobile phone at any time can speed up the smooth system, such as WeChat and QQ installed on Apple's mobile phone. These applications often have a lot of chat records and cached content, which will occupy a lot of memory of the mobile phone and affect the running speed of the mobile phone. It is recommended to clean up the cache records on these applications regularly.

4. Apple mobile phone takes up a lot of memory because of the quality of photos and pictures in live format, so deleting unnecessary files is one of the main ways to speed up the operation of the mobile phone. You can back it up to your computer or iCloud before deleting it, and then delete it in your mobile phone.

A large number of short messages will also drag down and affect the running speed of mobile phones. You can try to delete those useless verification code messages or blocked spam messages in your mobile phone.

6. Restart your phone regularly. When using the iPhone, most users will always keep the phone turned on, but in fact it is necessary to restart the phone regularly. Turning off the phone can help the iPhone get rid of things that have been occupying system resources.
