Now all apps on mobile phones need to use the network, and they all have caching technology. This can reduce the use of network traffic. However, with the passage of time, more and more files are cached, which greatly reduces the available space of the mobile phone. Frequent opening of QQ or WeChat software will prompt that the memory is insufficient and the cache needs to be cleaned up. The steps of cleaning are as follows:
1, go to the application center to download a Tencent mobile phone housekeeper, and then install it.
2. Open the housekeeper, click the health optimization function, and then select garbage scanning to automatically scan the software with many cached files. Then clean it up.
3. Open WeChat/Settings/General/Storage Space/Clean WeChat. You can also clean up the cache of WeChat.
