| self start control | Battery optimization | Background APP refresh |
| Clean up recent tasks | Need to slide manually | Slide up to close |
3. Evaluation of controversial solutions (from Bilibili Technology UP main experiment)
• Factory reset:The short-term effect is obvious, but 70% of users return to their original state after 7 days
• Third-party acceleration software:Among the 9 models tested, only 3 models actually released memory (CCleaner/SD Maid/Mobile Manager International Edition)
• Developer options adjustments:Forcibly turning off the animation may cause interface bugs
4. Long-term maintenance recommendations (Huawei/Xiaomi official customer service guide)
1.Monthly maintenance calendar
• Day 1: Check for system updates
• 10th: Clean social app cache
• 20th: Reboot device
• 30th: Back up important data
2.Hardware maintenance
• Avoid playing games while charging (battery temperature >40°C triggers frequency reduction)
• Use the original charger (unstable voltage may cause damage to the motherboard)
If trying the above methods still doesn't work, it may be a motherboard or memory hardware failure. It is recommended to give priority to official after-sales testing. Recently, OPPO/vivo and other brands have launched free testing activities. You can pay attention to the brand’s official website for information.
