iPhone
If you leave the cache unattended, your iPhone will run out of storage? –Why the iPhone can't be heard anymore?

The iPhone makes extensive use of cache in the system. It is used by too many functions / apps, and a huge amount of data and files are temporarily stored in the internal storage, so I can not explain each one, but "Settings" → "General" → "iPhone storage" If you open the screen in the order of, and look at "Other" at the bottom, you can see that it is consuming gigabytes of capacity.
