1. Reduce the frequent pop-up messages of qq groups, block some automatic pop-up chat messages of qq groups that are not commonly used, and then regularly clean up the junk messages in QQ groups, directly block or delete all unused groups, so as to avoid the accumulation of residual chat records and excessive occupation of disk capacity;
2. Click "Recent Contacts" in the qq list, and then click "Clear Recent Contacts List"; Then, select open interface manager-component management-folder options-to remove the checkmark in front of the recent contacts, so that the recent contacts are not displayed. This method is also useful.
3. Enter the system settings of your qq, turn off the sound in "Sound Settings" and block the ringtones of all your friends;
4. Turn on my computer, then click on drive C, and then find and enter the "program file \ Tencent \ qq \ your qq number" directory in turn to see if the chat database MsgEx.db is very large. If so, you can consider making a backup of the chat record and cleaning it up, or deleting the entire qq directory of ProgramFilesTencent, then logging in to QQ again and starting all over again, but remember to back you up.
Through the above simple settings, you can solve the problem that QQ takes up too much memory. If you encounter the same problem, you might as well try the above methods, hoping to help you.
