How to increase screen time on Xiaomi Redmi: from settings MIUI chipless

The screen is the main battery eater, and Xiaomi Redmi owners know firsthand how fast the phone drains when used actively. But what if we said that screen life can be increased by 30-50% without buying a new battery? We are not talking about radical measures like disconnecting the mobile Internet – it is enough to configure competently. MIUI, Optimize background processes and take advantage of hidden firmware functions.

In this article, you’ll find 10 working methods tested on models from the Redmi Note 10 to the Redmi 12, including budget and flagship versions. We’ll break down not only standard power saving settings, but also little-known tricks, from battery calibration to manually controlling CPU cores. And for those who are ready to sacrifice some functionality for the sake of autonomy, we will give instructions for deep optimization through the engineering menu and the following: ADB.

Important: All methods are safe for the device, but some require root or unlocked bootloader rights. If you are a beginner, start with the basic settings (sections 1-4), and experienced users can jump straight to advanced techniques (sections 5-8).

1. Optimization of screen settings in MIUI

The first thing you need to do is to reduce the load on the display without losing comfort. AMOLED- or IPS-It's not always necessary, because 120Hz is useful in gaming, but it's completely redundant when you read or browse social media.

Open the Settings. → Display and perform the following steps:

• 🔄 Set the refresh rate at 60 Hz (or 90 Hz for the Redmi Note 11 Pro)+ And it's going to cut battery consumption by 15 to 20%.
• 🌓 Activate automatic brightness, but manually limit the maximum level to 70-80% (in the adaptive brightness settings).
• ⏱️ Reduce screen timeout to 15–30 seconds (in the Sleep and Lock section).
• 🎨 Choose a dark theme or turn on it. AMOLED-black background AMOLED-This saves up to 10% of the charge on screens).

For models with AMOLED-displays (Redmi) K50, Redmi Note 12 Pro+) Disable Always-On Display (AOD) — This function eats up to 5 percent of the charge per night. AOD and reduce the display time to 5 seconds.

Configuring energy saving modes

MIUI It offers three preset power modes, but most users use only Balanced, unaware that ultramode can extend the screen by 2-3 hours without recharging.

Go to Settings. → Battery → Power saving modes and select:

• ⚡ Ultra mode: disables background activity, limits performance CPU/GPU It reduces the brightness of the screen, and it's suitable for emergency situations, when you need to "pull" to the socket.
• 🔋 Balanced: Optimal for everyday use, where you can manually disable Autosynchronization and Background data for individual applications.
• ⚡⚡ Performance: maximum power, but also maximum consumption. Use only for games or benchmarks.

Hidden chip: in Redmi on MIUI 13+ There's an undocumented Supersaving mode to activate it:

1. Open the Settings. → The phone.
2. Tap 5 times on the version MIUI (A notification will appear saying, “You have become a developer»).
3. Back to Settings → Additionally. → For developers.
4. Find the Super-Saving Battery option and turn it on.

⚠️ Warning: Supersaving disables notifications from most apps except for calls and SMS. Do not use it constantly, only in critical situations.

3. Management of background processes and applications

Even when the screen is off, many apps continue to devour the charge in the background: Social media (Facebook, Instagram), instant messengers (WhatsApp, Telegram), and geolocation services (Google Maps, Yandex.Maps) are the main culprits of fast discharge. They need to be “tamed”.

Do the following:

• 🚫 Limit background activity for unnecessary apps: Go to Settings → Annexes → Application management. Select an application (e.g. TikTok) → Battery → Limit background activity.

Turn off autostart.

Settings → Applications → Auto Launch

Prohibit access to geolocation

Settings → Privacy → Permissions → Geodata

Only during use

Set up synchronization.

Turn off automatic sync for Google Account and Mi Cloud (or set the interval 1 time in 6 hours).

For advanced users: use them. ADB, To completely block background activity for individual apps, for example, the team below will turn off background processes for Facebook:

adb shell cmd appops set com.facebook.katana RUN_ANY_IN_BACKGROUND deny

⚠️ Attention: After application ADB-Some notifications may be delayed, and to get it back, replace denial with allow.

Calibration of the battery and resetting statistics

Over time, the Xiaomi Redmi battery controller starts to misrepresent the charge level, leading to sudden shutdowns at 20–30% or, conversely, to a 1% freeze, which is solved by calibration, a procedure that resets the data about the charging cycle.

Calibration instructions:

1. Charge your phone to 100% and keep charging for another 1-2 hours after reaching the maximum.
2. Turn off the charger and use the phone until it automatically turns off (don’t turn it off manually!).
3. Do not turn on the smartphone for 5-6 hours - this will discharge the residual current.
4. Connect the charger and charge up to 100% without interruption.
5. Repeat the cycle 2-3 times for accurate calibration.

If calibration doesn’t help, reset the battery statistics through the engineering menu:

1. Dial in the dialer: ##4636##.
2. Go to the section Information about the battery.
3. Click Reset Statistics (confirmation may be required).

💡

After calibration, avoid using your phone while charging – this will knock down the battery controller data.

5. Advanced settings through the engineering menu

Engineering menu (MTK Engineer Mode or Qualcomm Diag allows you to fine-tune battery and processor settings that are not available in the standard interface.

How to open the engineering menu:

• For MediaTek processors, dial ##36446337##.
• For Qualcomm Snapdragon processors, dial ##4636##.

What can be changed to increase screen time:

• 🔋 Charge threshold: In Battery, set Charge to 80% (extends battery life) or Shutdown at 5% (prevents deep discharge).
• ⚙️ Clock frequency limitation CPU: V CPU Settings reduce the maximum frequency by 10-15% (for example, from 2.4 GHz to 2.0 GHz). This will reduce performance, but increase autonomy by 20-30%.
• 📡 Disable backup modems: In Telephony, deactivate DSDS Mode (unless you use two) SIM-cards) and VoLTE (if the quality of communication is normal without it).

⚠️ Warning: Changing the settings in the engineering menu can cause the phone to overheat or be unstable.Before experimenting, back up through Settings → Additionally. → Backup and reset.

6.Use of third-party utilities for optimization

If standard means MIUI They don't work, they'll come to the rescue from third-party apps, which allow you to control your battery consumption more deeply, disable unnecessary services, and even change the settings of the Android kernel.

Top-3 utilities for Xiaomi Redmi:

• 🔧 AccuBattery: Shows real battery wear, optimizes charging cycles and prevents overcharging, and can limit battery life to 80.
• ⚡ Greenify: Forcedly freezes background applications that cannot be disabled by standard means (e.g., MiuiDaemon system services.
• 📊 BetterBatteryStats: Shows detailed charge flow statistics across processor cores, sensors and applications. Useful for identifying "gluttonous" processes.

For users with root rights, we recommend:

• Kernel Adiutor: allows you to manually adjust the frequencies CPU/GPU, Stress and Deep Sleep Parameters.
• Servicely: Disables unnecessary system services (e.g. Google Play Services in the background).

Example of settings in Kernel Adiutor to increase screen time:

1. Open the CPU section.
2. Install Governor on Powersave (minimum power consumption).
3. In the section GPU Limit the maximum frequency to 500-600 MHz.
4. Activate Deep Sleep for all cores.

💡

The utility side gives you a 20-40% increase in autonomy, but you need to be careful. Always check the reviews and rating of the application before installing.

7. Hardware methods: battery replacement and cooling

If software methods don’t work, the problem may be physical wear and tear, with the average battery life of Xiaomi Redmi being 2-3 years (or 500-800 charge cycles), and then the capacity drops by 30-50%, and the screen life is reduced by many times.

How to check the wear of the battery:

1. Dial in the dialer: ##4636##.
2. Go to Battery Information.
3. If you look at Battery Health, if it's below 80 percent, you should change the battery.

Cost and features of replacement:

Additional hardware advice:

• 🧊 Overheating reduces screen time by 15-20%, use heat sink covers or avoid direct sunlight.
• 🔌 The quality of the charger affects battery wear.Use Xiaomi's original power supplies (e.g., use Xiaomi's original power supplies, 33W For the Redmi Note 11).
• 🔄 Charging cycles: try to keep the charge level in the range of 20-80% to extend the service life.

8.Alternative firmware for maximum autonomy

If you’re willing to take drastic measures, installing custom firmware can increase screen life by 30 to 70 percent, which involves removing unnecessary Xiaomi software (bloat), optimizing the kernel, and using lightweight shells.

The best firmware for autonomy:

• 📱 LineageOS: The naked version of Android without unnecessary services, consumes 20-30% less charge than the MIUI. Supports most Redmi models.
• ⚡ Havoc-OS: Lightweight firmware with advanced battery settings. Allows you to disable unnecessary sensors (for example, NFC gyroscope).
• 🔋 DerpFest: Optimized for gaming smartphones, but has power saving modes not available in standard firmware.

Instructions for installation (on the example of LineageOS):

1. Unlock the bootloader through the Mi Unlock Tool (requires a Mi Account binding and wait 7 days).
2. Install TWRP Recovery for your model (download from the official website twrp.me).
3. Download the firmware LineageOS and GApps (minimum package pico).
4. Boot in. TWRP, Make a full backup, then flash the firmware and GApps.
5. Clear the cache (Wipe) → Dalvik/ART Cache and reboot.

⚠️ Note: Installing custom firmware resets warranty and may cause some features to fail (e.g. Mi Pay or Widevine) L1 for Netflix HD). Before the procedure, check the firmware compatibility with your model on the XDA-Developers forum.
