Apple 4s, I only installed more than 2g software. Why did the monitor use 5g? How can I squeeze out some memory?
The system generally occupies 4G memory. All software will produce some cache more or less when used. For example, if my QQ is not cleaned for a month, it will generate 3G cache. Sometimes the memory occupied by software is not large, but the memory occupied by cache is very large. It is recommended to clean the software cache regularly to free up space.
