First inclusion: step-by-step activation of the smartphone

When you first turn on the Xiaomi Redmi 9T, the system offers a setup wizard. This process seems intuitive, but there are nuances that affect the future performance of the device. For example, the choice of region determines not only the interface language, but also the available Xiaomi services (for example, Mi Cloud or Mi Video may be limited in some countries).

Follow this algorithm:

• 🔋 Charging before turning on: connect your smartphone to the network for 10-15 minutes, even if the indicator shows a charge.
• 🌐 Language and region choice: Russia (region) and Russian (language) are the best choice for Russia. If you choose Europe, some functions (e.g., dual clocks) may not work properly.
• 📶 Wi-Fi connection: Use a 5GHz network if the router supports. on Redmi 9T This will speed up the download of system updates.
• 🔐 Mi Account: Link Xiaomi account – without it will not work cloud backup, device search and some features MIUI 12/13.

Select the region "Russia" for the correct operation of services

Connect to 5GHz Wi-Fi (if available)

Create or log in to Mi Account

Disable "MIUI Recommendations" in your account settings

Update the system to the latest version-->

Once you have completed the setup wizard, take your time to install the apps. First, check the MIUI version in Settings → About Phone. If it is outdated (below MIUI 13), update the system - this will solve the majority of bugs with performance and security.

Optimizing performance: how to speed up the Redmi 9T

Xiaomi Redmi 9T is equipped with a Snapdragon 662 processor and 4-6 GB of RAM, but even these characteristics do not save from the brakes if you do not set up correctly.

The first thing you need to do is turn off auto-runs of unnecessary applications.

1. Go to Settings → Applications → Application Management.
2. Select the Auto Start tab.
3. Turn off auto-run for instant messengers (except the main one), games and underused programs.

The second is to reduce the animation of the system, which will visually speed up the interface.

1. Activate Developer Mode by tapping 7 times on the MIUI version in Settings → About Phone.
2. Back to Settings → Additionally. → For developers.
3. Find the parameters of the animation scale and set the value of 0.5x or Disable.

💡

If your smartphone is getting hot, check the activity of apps in Settings → Battery → Battery use. Often the cause of overheating is the background processes of Facebook or TikTok.

Customization of gestures and controls

MIUI offers two navigation options: classic buttons (Back, Home, Recent) and gestures, which save screen space and speed up interaction, but require getting used to. Redmi 9T has three types of gestures:

• 👆 MIUI-gestures: swipe up to return to the main screen, swipe sideways to return back.
• 📱 Full-screen gestures: swipe from the bottom edge anywhere on the screen.
• 🔙 Android Gestures: Similar to Pixel or Samsung (swipe from the edge to go back).

To choose the best option:

1. Go to Settings → Display → Full-screen mode.
2. Choose the type of gestures and test throughout the day.
3. For fine-tuning sensitivity, use the gesture sensitivity slider.

The Redmi 9T feature is that when using full-screen swipe up and hold gestures, Google Assistant opens, not a list of recent apps. This can be changed to Settings → Apps → Default → Assistant and voice input.

Management of notifications and authorizations

By default, MIUI allows most applications to display notifications and use geolocation, which leads to quick battery discharge and curtain clogging. Setting notifications on Redmi 9T has its own nuances - for example, some system alerts (for example, from Mi Security) can not be disabled by standard means.

To clear the curtain from unnecessary notifications:

1. Press the notification in the curtain and select Settings.
2. Turn off the option to show notifications for unnecessary applications.
3. For important notifications (messaging, mail) turn on Priority Notifications.

Geolocation and other permissions are managed in Settings → Privacy → Permits. Pay particular attention to:

• 📍 Geolocation: Disable for applications that don’t need it (such as Galery or File Manager).
• 📸 Camera/Microphone: Limit social media access (for example, Instagram can use a microphone to target ads).
• 📱 Auto Startup: As mentioned earlier, it is a key performance factor.

💡

Disabling background activity for Facebook and Instagram could increase battery life by 15-20%
