After installing a new system, your phone needs to re-adapt, compile, and perform security scans for all apps in the background. This process places a high load on the CPU and memory, which may cause temporary lagging, heating, or faster battery drain.
Once this optimization is complete (usually within 2-3 days), your phone’s performance will be better than the previous version. To speed up the return to smooth performance, please try the following solutions:
I. System Self-Optimization
1. Charge and Let the Device Rest
The optimization process requires power and computing resources. We recommend connecting your phone to a charger and keeping the screen off during idle times (such as overnight). The system will usually complete the background optimization after one night, and the lag should disappear naturally.
2. Continue Normal Use
If you cannot leave the phone idle for long periods, simply use it as normal. The system will gradually complete the adaptation process as you use it. Please be patient and wait a few days.
II. Advanced Troubleshooting
1. Check for Other Causes of Lag
If the phone still lags several days after the update, it may be related to specific apps or settings. We recommend updating your apps to the latest versions via the App Market, clearing background apps, and ensuring you have enough storage space.
If the issue persists and seriously affects your usage, we recommend backing up your data and visiting a realme Customer Service Center with your proof of purchase. Our professional engineers will be happy to inspect the device for you.
