After iOS8. 1, Apple provided the function of "iCloud Photo Gallery", which uploaded the entire photo gallery in the system to iCloud, and provided two storage modes, one is to store the original photos in local and iCloud, and the other is to store the original photos in iCloud, and the optimized low-resolution preview photos are stored in iPhone. The latter can greatly reduce the local space occupied by photos. When users look back, they will download the original files from iCloud again, and there will be a circular download progress prompt in the lower right corner of the photos.

Step 2 support

This is one of the most important functions of using iCloud, because it gets rid of the wired synchronization that had to connect to iTunes before, but uses real-time methods to ensure that data is not lost.

Backups store all personal information on iOS devices that use the same account. To put it bluntly, that is to say, no matter which generation of iPhone or iPad you are, open iCloud and log in to this account, and all the information in the device will be backed up. The setting information of iCloud backup is very comprehensive, including which wallpaper, which application prohibits notification, and even the screen brightness you adjust will be recorded one by one. So when you recover from iCloud, this phone will be exactly the same as the device that provided backup before. Second, the photo gallery will be backed up to iCloud. The picture library is the "iCloud picture library" after iOS8. 1 mentioned above. Because the previous version did not have a perfect photo backup scheme, there will be an option of "camera film" in the backup, but now the two have been merged into one. Finally, in-app data, including your Weibo and WeChat login information, chat history, setting options and so on. In other words, your personal usage data in all downloaded applications will be included.

3. Manuscripts and data

This is mainly the manuscript data stored by Pages, Numbers, iMovie and other software. With iCloud Drive, this kind of manuscript data is no longer just a backup of in-app data, but an independent file, which is convenient to edit and use. Of course, this use can realize cross-platform real-time editing and real-time synchronization. Step 4 mail

There is nothing to say about this, including all the email information you set, as well as draft, classification or logo information.

Ok, after understanding the above, we can save iCloud space in a targeted way. Then you can open the second page and learn how to effectively use the 5GB free space provided by Apple!

1. Replace iCloud Photo Gallery with third-party cloud storage software.

This is the content that takes up the most space. For users who like taking photos a little, it is common practice to save a 4-5GB photo, not to mention the parents with their children, which is full of every moment of their children's growth. Then 128GB iPhone 6 is probably not rich.

Therefore, the first step must be to close iCloud Photo Gallery. So after turning off this function, once the device is stolen, aren't all the photos gone?

Of course not. At present, there are too many third-party cloud storage solutions that can provide free space for backup. By default, they are all automatically backed up in WiFi environment. You won't feel it at all, but the photo has been uploaded successfully. More importantly, the upper limit of this space can be freely expanded through various forms, and it is not difficult to obtain a few TB of free space. This solves the problem of photo synchronization and saves the trouble of taking up iCloud space for photos. 2. Turn off some in-app data backup.

Go to Settings -iCloud- Storage Space-Manage Storage Space, and you can see the detailed directory occupied by iCloud. Where the backup will have the names of all the backed-up iOS devices. Click to view the details of the space occupied by all backup applications.

Of course, you still need to close some content, which is the redundant part of backing up to iCloud. For example, the map file of Gaode Navigation, the system will back up the offline map as application data, which is a file of 1-2GB. Such files can be downloaded again at any time, will not be permanently lost, and do not need to be backed up at all. Or video project files edited by iMovie, or video files imported by some players, are also "big households" occupying space. Whether these need to be backed up depends on your own needs. Of course, I think these are not worth mentioning for WeChat data, so they are all closed. Through these two ways, you should be able to effectively help you slim down iCloud. Of course, if it is still not enough, then you can only be willful and spend money to upgrade the storage space. At present, it can rise to 20 GB per month in 6 yuan, 200 GB per month in 25 yuan and 500 GB per month in 68 yuan. Local tyrants 138 yuan can have 1tb of space to use.
