How to use Xiaomi phone: instructions from the first turn on to hidden features

Xiaomi smartphones have gained popularity due to a combination of powerful features, modern design and affordable price. However, their MIUI brand shell has unique features that can confuse beginners. This article will help you understand everything from basic setup to hidden features that will make using the phone as comfortable as possible.

Not only will we look at obvious features like screen customization or Wi-Fi connectivity, but we’ll also look at lesser-known features like how to optimize battery life, adjust control gestures, use smart home features, and even fix typical bugs. We’ll focus on the differences between Redmi, POCO, and Xiaomi’s flagship 13/14 series β€” where the settings are the same and where they require a customized approach.

If you have just unpacked the new Xiaomi or want to explore the capabilities of your device in more depth - this guide will be your guide. All recommendations are checked on the current versions of MIUI 14/15 and adapted to Russian realities (including work with domestic services).

First Installing and Basic Setup

When you first turn on a Xiaomi smartphone, the system offers to go through the initial setup wizard, which takes 5-7 minutes and includes key steps:

  • 🌐 Language selection (Russian available, but some system notifications may be duplicated in English)
  • πŸ“Ά Connection to Wi-Fi or mobile network (on models for Russia, frequencies are supported by default) LTE Band 20 and VoLTE)
  • πŸ” Setting up the screen lock (we recommend using a fingerprint) + pattern lock for balance of security and convenience)
  • πŸ“± Transfer data from your previous phone (via Mi Mover or Mi Cloud)

At the stage of setting up a Mi Account, many users are faced with a dilemma: register or skip. Without linking to a Xiaomi account, you will lose access to the cloud backup, device search when lost and some functions of the smart home, but you can avoid collecting location data. The alternative is to use a local account (available in Settings β†’ Accounts β†’ Add Account β†’ Local).
