What's in the iPhone's storage space? How do I clean it up?

Cleaning up the cache not only makes your phone lose weight successfully but also makes it faster. But do you know what's in the iPhone's storage space? Why does it take up so much space on your phone and can't clean it?
What's in the cache?
What exactly is the cache of iOS systems? Offline maps, program caches, browser caches, browsing pictures, and more. Specifically, weChat, your chat history, the open edifarting avatar, the videos you've seen in your circle, the wrong files that flashed back, and so on, will all be left on your phone as a cache.
Is the role of the cache good or bad? Why clean up the cache?
The advantage of caching is that it helps you keep all your operational records and deliver them to you as soon as you need them. This involves technical knowledge, simply put, the CPU processing speed and memory (not storage space) processing speed is completely not equal, the CPU is too fast, memory is too slow, so the middle need slot. If you do the same thing many times in the software, such as twice point to open the same person's avatar, the second click, the CPU will go directly to the rack to take the avatar to you, so that you can quickly see, do not have to wait for the first time like the avatar circle, and this shelf is "cache".
Since caching speeds up access, why should we clear the cache?
1. Save space
iPhones in the low storage space era often encounter situations where you're prompted to have no room when you take a photo, and you'll have to delete them one by one to make room.
Maybe you'll say, I'm a 128G, 256G phone, but in fact, we think about it when the 64G iPhone for us is also a "big space phone", but now say buy 64G mobile phone, will certainly attract people around the dissuasion. The reason is simple: super apps like WeChat, which cache lots of files to take over your phone, or an increasingly powerful camera, is the XXM of an ultra-high-definition photo from the iPhone 11 Pro Max. So it's still necessary to clean up the useless cache to save your phone's space, and there's always a full day unless you're a 512G phone.
2. Increase efficiency and address hoarding
Refreshing the browser over and over again is one thing a lot of people will do in the PC era, and when it comes to the mobile age, it becomes a one-and-a-half-time glance at friends or a constant slide. In this process, a lot of useless garbage occupied the phone space, cleaning the cache helped me successfully achieve a useful "break off."
How to clean up the cache quickly and easily?
1. Shutdown restart
A shutdown restart triggers an automatic cleanup mechanism to quickly clean up the cache.
2. Clean Up Safari's cache
Go to Settings - Safari - "Clear History and Website Data". In addition, you can turn off "automatic offline storage".
3. Clean Up WeChat Storage Space (Photos, Videos and Caches)
In the old version of WeChat, I believe that many people in cleaning up weChat cache will worry about whether the chat record will be deleted, the new version of WeChat clearly told you not, so bold lying it! The downside is that you just need to spend a little bit of traffic to re-download avatars, friends circle pictures, videos, and so on. The cleanup location is in "I" - "Settings" - "Universal" - "Storage Space" - "Cache Cleanup".
In addition, you can click on Chat History Management below to enter your personal chat history and click on the right exclamation point to direct clean up some of the pictures and videos of chat history. Doing so preserves text and voice records, but clears selected pictures and videos. If you want to clean up more clean, go to the chat window left slip delete chat record directly a pot end!
4. Clean up the cache of other software
The ability to clean up the cache is also mostly found in the settings for other software caches. Before that, you need to find out which software is to blame! Location in "Settings" - "Universal" - "iPhone Storage."
Previously, "other" was sometimes referred to as "system", which is the time when we most often wonder, why does the system take up so much space? But now that you're down, you can see that iOS 13 has explicitly told you that the "other" cache is divided into "system" caches and real "other" caches, yet you can't slim down directly on them.
5.iCloud or Google Photos To Store Photos
If you have iCloud space and don't have much demand for local images, consider uploading all your photos directly to iCloud to save space. This is done by Settings - "Photos" - open iCloud Photos and selects Optimize iPhone Storage.
Of course, if you have the conditions, you can also download Google Albums directly, choose to upload "High Picture Quality " (unlimited free storage space) in Settings - Backup and Sync" - and then free up space in "Settings" - "Manage device storage space" and limit the cache size so you can take unlimited photos! Of course, the premise is still not too much demand for local pictures.
6. Clean up voice memos
"Settings" - "Voice Memo" - "Clear Deleted Items" can help you clear deleted items immediately.
7. Clean up text messages and emails
Settings - "Information" - "Reserved Information" can choose to retain information for 30, 1 year, or permanent, and it's time to clean up your spam-filled "information."
Go to Mail and clean up your spam!
8. Clean Up Apple Music and Podcasts
Apple Music users can also go to Settings - "Music" - "Optimize Storage" to limit the maximum space for downloading songs from Apple Music. When turned on, when you exceed that limit, you'll automatically delete old songs that haven't been heard for a long time.
In addition to manually deleting downloaded podcasts, Apple Podcast users can open "Delete Play episodes" in Settings - Podcasts, so that the episode is automatically deleted 24 hours after the end of playback.
9. Back up, erase, restore your phone
The ultimate big way of nature is the brush machine! In "Settings" - "Universal" - "Restore" - "Erase all content and settings".
