How to solve the stuck phenomenon after Apple's mobile phone upgrade?

1, in fact, a lot of garbage will be cached when upgrading. If there are too many caches, it will take up too much memory space and affect the running speed of the mobile phone. Therefore, it is necessary to clear the mobile phone cache to alleviate the problem of mobile phone congestion.

2, you can turn it off regularly, usually for a week, because the mobile phone runs for a long time, just like people need to rest after working for a long time. After updating the system, the operating pressure of the mobile phone is even greater. Remember to turn off the phone regularly and let the phone have a rest.

3. In fact, Apple does not support downgrade, but some users have restored their mobile phones to the original system by jailbreaking. Although this method can be downgraded, it has certain risks. If it is not done well, it will cause the phone to crash and the ID to be locked. Therefore, it is not recommended for non-professionals to use this method to downgrade.
