Since the release of the new firmware IOS 7 on Apple's official website, it has been faced with a lot of controversy. The previously advocated saying that the iPhone 4S will not be stuck after upgrading IOS 7 has been defeated by the bloody fact. However, I have compiled a set of tutorial on upgrading the iPhone 4S to IOS 7 and I will share it with you today. At the same time, I will teach you how to escape from prison for your phone4s.
How to upgrade iPhone 4S to IOS 7
1. Delete unused apps, bulky files and other fragments
Reducing data storage in devices can significantly improve performance. Check how much storage space you have left in the settings. You can also view the space used by each app in descending order. If you find that the storage space is too full, unload the apps that take up more space and you think it is dispensable. Finally, it is better to keep more than 15% of the remaining storage. Of course, more storage will be better.
Note: sometimes, the application itself does not have much impact, but their related documents. For example, some e-magazines will download some inexplicable documents. If you read them often, you'd better delete them. This also applies to music, videos, podcasts, photos, documents, and other files.
2. Disable automatic background processes
Automatic background process is a more convenient function, but if it slows down the running speed of the system, this convenience is not worth it. The following three factors have the greatest impact:
App store background upgrade: go to the itunesapp store, find the auto download, and then switch off the upgrade option. Background synchronization: in the auto download, you can also stop the automatic synchronization of music, apps and books between Apple devices. Although manual synchronization is needed in the future, it does reduce the burden on the device.
Background app process: app running in the background often slows down the system, and sometimes causes flashback. To settings - General - background application refresh, you can turn off the background of all apps, or you can make individual settings.
3. Reduce dynamic effects
The parallax effect and 3D animation of IOS 7 make some users feel uncomfortable, which is a reason to turn it off, but even if you don't have this reaction, it's better to turn it off if it takes up some system resources and slows down the device. Go to settings, general and auxiliary functions to turn on the reduction of dynamic effects.
4. Turn off blur / transparency
IOS 7's notification and quick settings interface will have a translucent effect, which will take up some graphics processing performance, which is natural for the old iPhone. Go to settings, general and auxiliary functions to turn on enhanced contrast.
5. Fix keyboard lag
Keyboard lag is very annoying when typing. How to improve it? In the settings, go to icloud to turn off and turn on the documents and data. (if you don't need to store documents and data in icloud, it's better to turn off completely. ）Next, return to the main settings interface, general restore, and select Restore all settings. This will increase the keyboard speed.
6. Restart the phone
There is a classic line in the funny British TV series "it madman." have you tried to restart the computer? "IPhone users often keep their devices on all the time, and many never even turn them off manually. Experienced computer users know that restarting the computer can clean up temporary files and free up memory, which is also applicable to smart phones. For the iPhone, there's another benefit: occasionally letting the phone run out of power can also help with battery life.
7. Erase all content and settings
If none of the above methods works, it's the ultimate weapon, erase everything and start over with a clean system. But it's better to back up your phone before you do this, and you can recover once you regret it.
Go to settings general restore and choose to erase all contents and settings. Some users restore the backup after doing this step, which may recover the previous problems. Therefore, it is better to manually download the app from the app store.
