为什么应用占内存很少但内存不够(为什么应用少但占用内存很大)

Mobile phones require a certain amount of memory to run the entire Android system. Some system programs and third-party programs will also start automatically when the phone is turned on, so they take up a lot of memory, resulting in a relatively high memory usage after booting.
If you are using a vivo phone, it is recommended that you often use one-click acceleration to clear the running memory of the phone, and enter iButler--(Application Management/Software Management)--Permission Management--Close unnecessary self-starting software in Auto-Start. .

The phone prompts that the memory is full/insufficient memory or needs to optimize the memory. We recommend that you:
1. Delete unnecessary data and applications. :Smart Manager (Memory Manager)-Storage Space/Memory.
2. Close unnecessary applications: Click the recent tasks key in the lower left corner of the screen - click the "X" in the upper right corner of the application you want to close/click "Close All" below.
3. If the phone supports memory cards, move the multimedia files to the expansion card or set the shooting storage path to the expansion card. If you do not have a memory card, it is recommended to move multimedia files to your computer regularly.
4. Uninstall software or files that are not frequently used.
If the phone memory is still insufficient after the above methods, it is recommended to back up the data in the phone (contacts, messages, photos, etc.) and try to restore the factory settings.

Most smartphones will always show that there is not enough memory at the end of use. It is shown that there is still seven gigabytes of memory space, but the real memory is completely lost in an instant due to the crowding of many background self-starting applications or the buffering of some large applications. This is an unavoidable flaw in Android phones. The only solution is to choose a new high-memory mobile phone as an emergency.
