In this article, we will look at all the stages of familiarization with the device, from unpacking to advanced interface settings.
You’ll learn how to avoid the typical bugs of the initial launch and where the most useful tools are hidden, which are not mentioned in the basic instructions. The correct configuration of notifications and power consumption will make using the smartphone comfortable in the first days.
Initial activation and account setting
Once the device is turned on, the system will suggest selecting a language and connecting to the Wi-Fi network.

MIUI interface and navigation

Navigation is done in three ways. The classic method uses three virtual buttons at the bottom of the screen. However, the more modern and ergonomic is gesture control. A swipe from the bottom up returns to the desktop, a swipe from the side back, and a finger delay from the bottom causes a menu of running apps.
- 📱 The control panel is called by swipe down from the upper right corner, where the Wi-Fi, Bluetooth and flashlight switches are located.

Energy efficiency and battery operation
The Redmi Note 9 has a 5020 mAh battery, which is one of its main advantages. However, to make the phone live long, not only on paper, but in reality, you need to set up the power saving system correctly. MIUI aggressively kills background processes, which can lead to miss notifications.
In Settings → Battery, you can select a performance profile. For everyday tasks, Balanced mode is optimal. Battery mode limits background activity and brightness, prolonging the running time, but slowing down the system response.
It is important to set up auto-run applications. By default, many programs cannot run on their own, which saves charge, but blocks messengers. Go to the Security app, select Permissions → Auto-Run and enable the necessary programs (WhatsApp, Telegram, mail).

To protect your personal data, use encryption. In modern versions of Android and MIUI, it's on by default, but it's important to set a strong pin or pattern lock. Biometrics is convenient, but digital code remains the primary access key.
- 🔒 Hiding applications allows you to remove icon programs from the desktop, access to them – only through a password.
- 🛡️ Protection against theft requires enabling geolocation and binding to Mi Account for remote blocking.
- 👶 Guest mode is useful when you give someone a phone for a while to restrict access to only calls.
