The memory occupied by the mobile phone is not only those applications that we downloaded, but also some downloaded applications cache a large number of records, resulting in insufficient memory of the mobile phone, and the mobile phone is easy to get stuck and crash, so the cache needs to be cleaned up. The steps of cleaning are as follows:

1. Open the housekeeper, click garbage cleaning in health optimization, and then select garbage scanning. Just clean up immediately after scanning and press Finish.

2. Uninstalling uncommon software can reduce the space occupied by the mobile phone.

3. Turn off the software when it is not needed. Background operation will not only use traffic, but also occupy the memory of the mobile phone when it is running.

4. Don't update the mobile phone system easily. Many new mobile phones are more prone to lack of memory and slow response after updating their new systems.
