Will jailbreaking an iPhone affect the performance of the phone?

After the iPhone is jailbroken, it will have an impact on the performance of the phone, which is roughly as follows:

1. Jailbreaking will make the system unstable, especially after the system permissions are changed, many services will be affected. ;

2. Jailbreaking will make the system more power-consuming, because themes need to be running all the time, and many plug-ins will also run in the background;

3. Don’t do it randomly Upgrade to the latest system. If you upgrade, the jailbreak may become invalid and many original programs cannot be used;

4. The system may become unsafe after jailbreak because if the user does not change the highest authority password in time after jailbreak , it is very likely to be hacked and obtain private information.

Advantages of jailbreaking:

1. The system permissions are very high. You can optimize the system yourself, modify system files, and install more software with high system permissions to achieve more advanced Functions!

Disadvantages of jailbreaking:

1. It consumes electricity. After jailbreaking, the system will always have some processes to maintain the jailbroken state. Depending on the number of system-level software (deb format) installed, the power consumption speed increases by about 10 to 20% after jailbreaking.

2. It may cause system instability. Having high system permissions also comes with the risk of system crash. Do you understand this? You can modify it, but you cannot guarantee that it will always be correct. to modify it. Therefore, it is better to have system-level software in short supply than in excess, and do not install it randomly without understanding its purpose.
