How to improve the speed of the Internet on Xiaomi: from settings to firmware

Slow internet on Xiaomi is a problem that one in three users encounter, and the reasons can be in the settings of the smartphone, as well as in the features of the firmware. MIUI. In this article, we will analyze all possible ways to speed up the Internet: from basic settings to hidden functions that the manufacturer does not advertise.

It's important to understand that the speed of the Internet depends not only on the smartphone, but also on the provider, router, network congestion. However, even under ideal external conditions, the wrong settings Xiaomi can "cut" the speed on the Internet. 30-50%. We tested all the methods on models from Redmi Note 10 Xiaomi 13 Ultra - results in the table below.

If you've tried rebooting your router and your smartphone before, but the speed hasn't increased, don't be quick to blame the provider.
