How to Set Up Xiaomi’s New Smartphone: A Complete Guide from Unpacking to Fine Optimization

The first steps with the new Xiaomi: what to do immediately after unpacking

You’ve just become the lucky owner of Xiaomi’s new smartphone — whether it’s the flagship Xiaomi 14 Ultra, the budget Redmi Note 13 or the gaming Black Shark 6. But before you dive into the world of MIUI, you should properly prepare the device for work. The first turn on is not just a press of the power button, but a whole ritual, on which further stability of the system depends.

Many users make a common mistake: they rush to install all the apps from Google Play or migrate data from an old phone without optimizing the basic settings. The result is lags, fast battery drain or network connection problems in a week. This article will help avoid such scenarios and set up Xiaomi so that it works quickly, safely and as efficiently as possible.

The thing about MIUI is that it offers hundreds of hidden features that aren't obvious at first glance, like Ultra Battery Saver mode, which can extend autonomy by 30 percent, and App Vault settings can speed up access to commonly used tools, but that's all in order.

Preparation for the first switching on: charging, SIM-card

Before you press the power button, do three key actions:

• 🔋 Charge your smartphone to a minimum 30-40%. Modern Xiaomi supports fast charging (e.g. Xiaomi) 13T Pro is charging on 100% post 19 ) but the first time you turn on when the battery is discharged may cause the power controller to malfunction.
• 📱 Install. SIM-card and memory card (if supported) in hybrid slot models (e.g. Redmi Note 12 Pro)+) You have to choose between the second. SIM Remember, the memory card format should be exFAT or FAT32 — NTFS unsupported.
• 🔑 Prepare your Mi Account and Google login details, and without these accounts, you won’t be able to use branded services (like Mi Cloud for backups) and the app store. If you don’t already have a Mi Account, register it in advance at account.xiaomi.com.

Important: if you buy Xiaomi hand-held, make sure to complete a factory reset (Settings → Phone → Reset), even if the seller claims that he has already done everything. In 2023, there were more than 12,000 cases of fraud with Mi Account tied in Russia and the CIS.

First Enablement and Basic Configuration of MIUI

When you first turn on Xiaomi, you are greeted by the MIUI Customizer, and it is important to take your time and choose your options carefully, as some of them will be difficult to change later.

1. Language and region choices: Indicate Russia or your country, which will affect the services available (e.g. Mi Pay does not work in all regions); if you choose China, some features (e.g. Google Services) may not work properly.
2. Wi-Fi connection. Use a stable 5GHz network if the router supports.This will speed up the download of system updates. Avoid public hotspots (such as in a cafe) - they can block Xiaomi servers.
3. Sign in. First log in to Mi Account, then Google. If you miss this step,Later some functions (like Find Device or Mi Cloud Backup) will be unavailable until you log in.
4. Data portability: If you choose to transfer from an old phone, use a USB-C to USB-C cable (for Android) or Move to iOS (for iPhone). Wireless transfer over Wi-Fi Direct is slow and can be interrupted.

Once the customization wizard is complete, the system will suggest updating MIUI. Don't delay it! In the first batches of smartphones, there are often critical bugs that are fixed in the first updates. For example, the Xiaomi 12T Pro had an overheating camera issue when it released, fixed in the MIUI 14.0.3 update.
