How does iphone 6s clear data?

Open the settings first, then find GM, open it and click Restore.

Then click Erase all contents and settings, and finally enter your local password. Click Finish to clear the data.

Ways to clean up iPhone junk and cache:

Delete browser cache

In the system settings, we can manually clear the cache on the browser.

(1) Open the settings in the general-use-management storage space, in which we can see how much memory space many apps occupy.

(2) Find Safari and click on it to see website data and offline reading list. You can click Edit Delete in the upper right corner.

Clean up the application cache

The cache of the app itself is actually terrible. If you don't clean it up in a day or two, many will be as high as hundreds of megabytes. Take the app WeChat that everyone is basically using as an example. We can clean the cache like this:

(1) Open WeChat and click My Settings-Settings-General in the lower right corner.

(2) Click to clear the storage space of WeChat, and then WeChat will scan to clear the cache of friends. Don't read less, it may make a lot of room for you here.

Forced restart

Forced restart (also called cold restart) can help iOS devices clean up temporary files. If forced restart is carried out regularly, it will run more smoothly. Many people sometimes get stuck, and it will be much smoother after forced restart, and so will Android devices.

Press and hold the home button and the power button at the same time for about 10s, and the device will automatically shut down and restart.

Delete stand-alone software

Some fruit powder may not be known, and some software that comes with iPhone can be uninstalled now. For example, Numbers, Page, GarageBand, etc. We generally don't need these softwares at all. Press Delete decisively!

With the help of cleaning software tools

Recommend several foreign cleaning app:Phone expander, PhoneClean, Ifunbox, Imazing and Decipher Phone Cleaner, etc. If you use them occasionally, the effect still exists. If you want to escape from prison, you can try to install some management software, such as Ryan's CacheClearer.

Restore factory settings

This is the ultimate killer and should only be used as a last resort. If all the above methods have been tried and the memory of the mobile phone is still tight, you can only restore the factory settings. However, before restoring the factory settings, please remember to make a backup on iTunes.

(1) Open Settings-General-Reset-Reset all contents and settings.

(2) After the factory settings are restored, download the desired app again and restore the contacts, text messages, songs or movies on iTunes.
