Method 1: Exit the programs running in the background and press the HOME button (some Android can click the HOME button) to bring up the recently run programs, and then slide the programs in the program list left and right or up and down to exit the programs running in the background one by one. Method 2: Restart intelligence regularly, just like a computer. It will get slower and slower after running for a while. Although there is special management, it can clean up and accelerate, but the effect is still limited. At this point, restarting the manual operation can restore it to a fast and smooth state. So every once in a while, it is worthwhile to take a minute to restart it so that it can run again. Method 3: install garbage management, such as 0 housekeeper and Tencent housekeeper, which integrates many functions such as antivirus, management and cleaning acceleration. Among them, the garbage cleaning acceleration function can quickly and effectively clean up garbage files and quit the programs running in the background, thus slimming down and speeding up. Method 4: Delete the uncommon ones except some common ones such as browser, ss, Weibo and management, and other temporary ones, especially games. Remove and uninstall in time when not in use, and reinstall if necessary. Method 5: Try not to use internal storage space to support memory expansion, and try to match an SD. The data should be stored in the extended TSD as much as possible and installed in SD as much as possible, so as to ensure that there is enough space left in the memory. If memory expansion is not supported, data can only be stored in memory and can only be installed in memory, but we try to use too little memory space. Method 6: If infected with the virus, not only our information will be leaked, but also our operation may be slowed down. Through the management introduced in the first method, the virus in the library can be removed. Method 7: Restore the factory settings. After a period of use, a large number of fragmented files will be produced. Even if it is accelerated or restarted by management, it will not achieve good results. At this point, it is necessary to restore the factory settings. Restoring factory settings is like reinstalling a computer system, which can restore the system to its initial state.
