13.4 Why does my phone run slowly when the battery
level is low?
When your phone's battery level is less than 10%, to preserve the battery life, your phone's
performance will be restricted.
13.5 Why does the game app run slowly?
1. Try the game app using another phone. If the game app also runs slowly, this problem is
caused by the game app instead of your phone.
2. Check whether your phone is hot. According to Huawei specific heat protection design,
your phone's performance is limited to provide comfortable touch feeling and to protect
the phone. You can set your phone at a proper temperature when you play games on your
phone, and set power saving mode to Smart under Phone Manager > Power saving.
3. Check whether the battery level is low. At low battery level, to extend the phone usage
and protect your phone, your phone's performance is limited. You can charge your
phone.
4. When you play games, check whether any download task is implementing on the
background. File copying operations increase the load of the phone.
5. If the game requires network connection, check the network status. The performance is
also affected by unstable network connections.
6. If the issue is not caused by any of the above reasons, refer to the solution to slow system
performance.
