How to Set Up Xiaomi Redmi Note 7: From First Launch to Thin Optimizations

Xiaomi Redmi Note 7, released in 2019, is still a popular choice due to the balanced characteristics: Snapdragon 660 processor, dual camera 48+5 MP and a capacious battery of 4000 mAh. However, even after years of operation, many users do not use the full potential of the device. This article will help not only to properly configure the smartphone after purchase or reset, but also to optimize it for modern tasks – from overclocking performance to fine-tuning the camera.

The Redmi Note 7 features MIUI firmware, which combines customization with pitfalls like advertising and background processes, and we'll figure out how to turn off unnecessary services, customize gestures, improve autonomy, and even unlock the bootloader to install custom firmware, and if you've purchased a used device, you'll find a checklist to check its status before setting up.

Preparing for the first inclusion: what to do before setting up

Before you start setting up, make sure your smartphone is ready to go, which is especially important if you bought the Redmi Note 7 with your hands or after long storage.

Check the package: there should be a cable in the box USB Type-C, power supply 5V/2A (10W), paperclip SIM-The absence of the original charger is a cause for concern: unoriginal units can damage the battery. Also inspect the case for dents or autopsy marks - this may indicate unskilled repairs.

  • πŸ”‹ Charging before turning on: connect your smartphone to charge for 30-60 minutes, even if the indicator shows a charge.
  • πŸ“Ά Verification IMEI: dial *#06# - two 15-digit numbers should be displayed on the screen (for two digits). SIM-If the card is replaced by a β€œnull” or error, the device could have been recovered after theft.
  • πŸ” Screen Diagnostics: Check the sensor for dead zones with the test in the engineering menu before setting up (#4636##).

⚠️ Note: If the smartphone requires a password from the previous owner when it is turned on (even after resetting via Recovery), this means that the Mi Account has not been untied. In this case, you will need official unlocking through the service center Xiaomi – independent attempts to bypass can lead to blocking. IMEI.

First Enablement and Basic Configuration of MIUI

After pressing the power button, you will see the Redmi logo, then the MIUI initial setup wizard. Here it is important not to miss the key points that will affect the future work:

  1. Language and region choice: Install Russia as a region, which will disable unnecessary services for China (e.g. Mi Pay) and activate support for LTE Band 20 (important for European operators).
  2. Wi-Fi connection: Use a 5GHz network if the router supports it, this will speed up the download of updates. Avoid public networks (for example, in cafes) - they can block Xiaomi servers.
  3. Sign in to your Mi Account: If you don’t have an account, create it via Google or email. Without a link to your Mi Account, you won’t be able to use a cloud backup, unlock a bootloader, or recover data after a reset.
  4. Fingerprint setting: The sensor on the Redmi Note 7 supports up to 5 fingerprints. Record your finger from different angles, which will improve recognition accuracy.

In the β€œPersonalization” phase, the system will suggest turning on MIUI recommendations and usage analytics. Disable both items – they send data about your actions to Xiaomi servers and slow down the smartphone. Also deactivate the Auto Update of apps in Google Play – this will save traffic and battery power.

Optimizing performance: how to speed up the Redmi Note 7

The Redmi Note 7 on the Snapdragon 660 will handle most everyday tasks, but over time, MIUI can β€œslow down” due to background processes.

  • πŸ”„ Reset battery settings: if the smartphone suddenly turns off at 20–30% charge, go to Settings β†’ Battery β†’ Settings β†’ Resetting battery statistics.

CPU overclocking (optional): In the same Developer Menu, activate Fixed CPU Frequency and set the maximum frequency for all cores. This will increase performance by 10-15%, but reduce battery life. Use this mode only for games or video rendering.

Camera setup: how to get the maximum from 48 MP

The Redmi Note 7 dual camera (Samsung GM1’s 48 MP core module + 5 MP depth meter) is capable of more than it seems. By default, MIUI uses pixel binning, reducing the resolution to 12 MP for better detail. To engage the full 48 MP, follow the following steps:

  1. Open the Camera app and go to Settings (βš™οΈ) β†’ Photo resolution.
  2. Select 48 MP (the 48M sign will appear in the top corner of the viewer).

  • πŸ”„ White balance: 4000K warm-light, 6000K cold-hearted.

How to save the Pro Mode settings by default?
In MIUI 12+, the Pro Mode settings are reset when the camera is closed. To save presets, use third-party applications like Open Camera or GCam (requires an unlocked bootloader).

For video, activate Stabilization and 4K@30fps in settings. Avoid 60fps, because of the hardware limitations of the Snapdragon 660 video will be soapy. Use CapCut or KineMaster for editing, which are optimized for Xiaomi.

Network and Communication: How to Improve Signal and Internet Speed

The Redmi Note 7 supports 4G LTE Cat.12 (up to 600 Mbps), but by default may not work at full power. Communication problems are often associated with improper APN settings or network conflict.

Optimization of mobile Internet:

  1. Go to Settings. β†’ SIM-maps and mobile networks β†’ [yours SIM] β†’ Access points (APN).
  2. Create a new APN with your operator’s settings (for example, for MTS: Name: MTS Internet, APN: Internet.mts.ru).

Battery and charging: how to extend the life of the battery

The 4000mAh Redmi Note 7 battery provides up to 1.5-2 days of moderate use, but over time, capacity declines due to improper charging or background processes. Here's how to maximize battery life:

  • πŸ”Œ Optimal charging mode: Use the original power supply 5V/2A (10W). Quick Charge Charge Charge Fast Charge 3.0 It's supported, but it speeds up battery wear. 20% and charge higher 80% (ideal range for lithium polymer batteries.Switch off the smartphone from charging after reaching 100% β€” Continuous network connection reduces service life.
  • ⚑ Energy saving: Activate Battery Mode in Settings β†’ Battery β†’ Battery modes β†’ Balanced. Turn off Autobrightness and set the brightness to 50-60% manually. β†’ Display. β†’ Sleep mode reduce the timeout to 15 seconds.

Battery calibration (if the charge indicator is lying): fully discharge the smartphone before turning it off, then charge to 100% without interruption. Repeat the cycle 2-3 times. This will reset the power controller data.

To check the status of the battery, use the AccuBattery application (showing real capacity) or the engineering menu:

To speed up charging, activate Air Mode while connecting to the network, which will turn off 4G/Wi-Fi/Bluetooth modules, reducing charging time by 15-20%.

Unlocking the loader and installing custom firmware

If you don’t like standard MIUI (due to advertising, restrictions, or slow updates), you can install an alternative firmware like LineageOS or Pixel Experience.

Important: unlocking erases all data and resets the settings to factory, Xiaomi also requires binding to Mi Account and waiting 7 days after the device is tied (the rule is introduced to combat theft).

  1. Preparation: Download Mi Unlock Tool from the official website. Enable USB Debugging in Settings β†’ For Developers. Link the device to Mi Account in Settings β†’ Xiaomi Account β†’ Mi Cloud.
  2. Unlock: Connect your smartphone to your PC in Fastboot mode (press Power + Volume Down when turned on). Launch the Mi Unlock Tool, log in to the same Mi Account and follow the instructions. Once successfully unlocked, the device will reboot from a clean MIUI.

For custom firmware installation:

  1. Download TWRP Recovery for Redmi Note 7 (lavender version) and firmware (e.g. LineageOS 18.1).
  2. TWRP via fastboot: fastboot flash recovery twrp.img fastboot boot twrp.img
  3. In TWRP, run Wipe β†’ Format Data (enter yes), then run the firmware and GApps (Google services).

⚠️ Warning: Installing unofficial firmware will void the warranty and may result in a lock IMEI, If something goes wrong, check the version compatibility before you run the firmware. TWRP The Redmi Note 7 is codenamed lavender, and the Redmi Note 7 Pro is violet).

What to do if there is no network after the firmware?
If mobile Internet or Wi-Fi is lost after installing custom firmware, modem drivers are most likely missing. Download the firmware.zip file for your model and thread it through TWRP without wipe.
