Xiaomi Redmi 7: How to set up, unlock and speed up your smartphone in 2026

The Xiaomi Redmi 7, released in 2019, is still a popular budget smartphone due to its balanced performance and deep customization capabilities. However, many users face challenges from slow operation on MIUI 12+ to blocked bootloader when trying to firmware. In this guide, we will discuss all the key aspects of working with the device, from basic settings to advanced tricks that you will not find in the standard instructions.

Redmi 7 features a Snapdragon 632 processor and 2/3/4 GB of RAM, which, when optimized properly, ensure smooth operation even in 2026. But without the right settings, the smartphone can “brake” due to background MIUI consumption and pre-installed Xiaomi services. We will show how to remove unnecessary applications, unlock the bootloader legally and even increase performance through the engineering menu – without the risk of “bricking” the device.

Basic setup after purchase or reset

The first Redmi 7 activation is accompanied by the MIUI setup wizard, where it is important not to miss key points. For example, not syncing with Mi Account at this stage can then cause problems with unlocking the bootloader. If you buy a used device, be sure to reset via Settings → About Phone → Resetting will remove the link to the previous owner.

After discharge:

• 🔄 Choose a language and region (important for the correct operation of Google Play). For Russia, specify "Russia" to avoid problems with geoblocking services.
• 🚫 Turn off "Recommendations" MIUI" and "Personalization of advertising" in the section Settings → Privacy – This will reduce the burden on the processor.
• 📱 Connect your Google account (not Mi Account!) first – this will provide access to the Play Market and backups.
• 🔋 Activate Battery mode" → "Energy saving" to extend the operating time (especially relevant for versions with 2 GB of RAM).

Note that if the smartphone requires a password from the previous Mi Account after reset, it means that the device is tied to the Xiaomi account, in which case you will need to officially unlock through the i.mi.com website (for more information in the section on unlocking).

Optimizing performance: how to speed up the Redmi 7

Redmi 7 on MIUI 12/13 often suffers from lag due to aggressive memory optimization and background system activity.

1. Activate Developer Mode: Go to Settings → About Phone and click on MIUI Version 7 times.
2. Back to Settings → Additionally. → For developers.
3. Find the parameters of the animation scale (all three points) and set the value to Disable.

Next, remove unnecessary system applications (no root):

adb shell pm uninstall --user 0 com.miui.analytics


adb shell pm uninstall --user 0 com.xiaomi.ab




adb shell pm uninstall --user 0 com.miui.cloudservice

These commands will remove Xiaomi’s analytics, advertising services, and cloud (executed via ADB on PC).For a full list of junk packages, use the MIUI Hidden Settings utility from the Play Market.

A critical feature of Redmi 7: at low charge (less than 15%), the processor is automatically limited to 1.4 GHz, which causes strong brakes. To avoid this, turn off the option "Limited Low Charge Performance" in Settings → Battery → Battery settings.

Unlocking the loader and installing custom firmware

Officially unlocking the bootloader on Redmi 7 (codenamed onclite) is possible through the Mi Unlock Tool, but since 2021 Xiaomi has tightened the requirements.

• 📱 Link the device to Mi Account (must confirm email and phone!).
• ⏳ Wait 72–168 hours after the binding (depending on the region).
• 🔗 Use the original USB-cable (Chinese "nouneim" cables often cause the Couldn't unlock error).
• 🖥️ Run Mi Unlock Tool on Windows PC 10/11 (MacOS and Linux tools do not work).

Step-by-step:

1. Download the official Mi Unlock Tool (version no lower than 5.5.224.30).
2. Enable OEM Unlock in Settings → For Developers.
3. Turn the phone into Fastboot mode: turn off the device, then press Power + Volume Down.
4. Connect your smartphone to your PC and launch the Mi Unlock Tool on behalf of the administrator.
5. Log in to the same Mi Account as on your phone and follow the program instructions.

Once unlocked, you can install custom firmware like LineageOS or Pixel Experience. Popular builds for Redmi 7:

⚠️ Warning: Installing unofficial firmware will void the warranty and may result in loss IMEI or problems with the module Wi-Fi/Bluetooth. Before the firmware, make a backup copy of the section EFS through TWRP!

Battery problems: how to extend the life of the battery

Redmi 7 is equipped with a battery capacity of 4000 mAh, but in 2-3 years its capacity can fall to 60-70% of the original.

• 🔋 Fast discharge (more than 1% per minute in simple).
• 🌡️ Overheating during charging (above 40)°C).
• ⚡ Charging with “jumps” (for example, from 80% immediately to 100%).
• 📉 Sudden shutdown at 20–30% charge.

To check the battery status, type in the dialer code: ##4636## → select Battery Information. Health should show Good. If Unknown or Dead is specified, it is time to change the battery.

Advice on extension of service:

• 🔌 Do not use "quick charging" 18W constantly - better to charge the current 10W (5V/2A).
• ☀️ Avoid overheating (do not leave your phone in the sun or near heat sources).
• 🔄 Calibrate once every 3 months: completely discharge the phone before turning off, then charge to 100% without interruptions.
• 🛌 Don’t leave the device on charge overnight – turn it off after 100%.

💡

If the phone stops turning on after it's completely discharged, plug it into charging for 10 to 15 minutes, even if the light isn't on, often enough to "reanimate" the power controller.

Camera Settings: How to Make a Photo Better

The main camera Redmi 7 - 12 MP (f/2.2) with phase autofocus, but by default the photos are dull due to aggressive processing MIUI Camera.

1. Open the camera settings (cog in the upper right corner).
2. Turn off HDR in automatic mode (only in bright light).
3. Set the resolution of the photo at 12 MP (4:3) – this will reduce the cropping of the frame.
4. Activate the grid for the correct composition.

For advanced users, we recommend installing Google Camera (GCam) with settings for Snapdragon 632.

• 📷 BSG GCam (Stable for weak processors).
• 🔍 Urnyx05 v2.8 (Supported by Night Sight).
• ⚡ Greatness GCam (optimized for Xiaomi).

Settings for Redmi 7 GCam:

Config:


Model: Pixel 3 (for better HDR processing)




AWB: Kawase (for natural flowers)




Noise Model: High (for noise reduction)




Disable Zoom (avoid digital zoom)

⚠️ Note: When shooting a video in 1080p@60fps The phone is very warm - use this mode only when necessary. 1080p@30fps.

Reset and unlock if you forget the pattern lock
