Poor performance. Because the Mi 13 is an older phone, and System 140210 is an older version of its MIUI system, there may be some performance and stability issues.
If you want to get a better experience, it is recommended to upgrade to the latest system version, or consider replacing a new phone.
That's pretty good. That's good.
After upgrading the mobile phone to this version of the system, you will find that the battery life has a certain improvement to maintain the basic level, and there is no problem in the overall use. And the degree of optimization is relatively good.
