How to increase screen time on Xiaomi: from settings MIUI hardware-wise

Screen time on Xiaomi smartphones is one of the most painful topics for owners of devices with a high-end smartphone. AMOLED-And it's also a big display and a big social media experience, even flagship models like Xiaomi. 14 Ultra or Redmi Note 13 Pro+ discharge 4-6 hours of intense video or game viewing, and budget devices barely reach 3 It's not just because of the battery capacity, it's because of the power management algorithms. MIUI, background processes and even in the default screen settings.

Many users mistakenly believe that it is enough to turn on the energy saving mode or reduce the brightness - but this gives an increase in all the energy saving mode. 10-15%. In fact, to increase screen time in the 1.5-2 And once you do that, you need a complex intervention, from shutting down unnecessary services to changing the kernel parameters through the engineering menu. 7 working methods, including hidden functions MIUI 14/15, Optimization for games and even hardware modifications for advanced users.

It's important to understand that screen time and battery life are different things: the first is measured only when you're using a display (games, videos, instant messengers), the second includes standby time, and we'll focus on the first one, because it's critical for gamers, streamers and those who work a lot with the phone.

1. Optimization of screen settings: brightness, frequency, color palette

Let’s start with the most obvious – the display that consumes up to 40-60% Even small changes here will give a noticeable increase in screen time.

The first thing you need to do is turn off the automatic brightness. MIUI often overstates brightness unnecessarily, especially indoors. 30-40% (depending on the lighting, it will save you 15-20% charge-by-charge 8 hours of use. Pathway to settings:

Settings → Display → Brightness → Disable “Automatic adjustment”

The second step is to reduce the refresh rate of the screen. Most Xiaomi (except budget models) defaults to 120Hz or 90Hz, which is beautiful but voracious. Switch to 60Hz through:

Settings → Display → Screen refresh rate → 60 Hz

⚠️ Note: On some models (e.g, POCO F5) Forced frequency reduction to 60 Hz can cause micro-stuttering in games, in which case leave 90 Hz and compensate for the flow with other methods.

The third item is the color palette. AMOLED Cinema or Saturated looks spectacular but requires more power to display bright colors.Select Standard or sRGB in:

Settings → Display → Color scheme

• 🔦 Brightness: 30-40% manually (savings) ~15%)
• 🔄 Frequency: 60 Hz instead 120 Hz (savings) ~20-25%)
• 🎨 Color scheme: Standard instead of Saturated (savings) ~5-10%)
• ⏱️ Screen timeout: 15-30 seconds (in Settings) → Display. → Son)

2. Power modes setting: hidden functions MIUI

MIUI It offers three standard energy saving modes, but they are limited. To really increase screen time, you need to use hidden kernel settings and disable background processes that Xiaomi does not show the user.

First, we activate the ultra-power saving mode (not available on all models):

Settings → Battery and performance → Battery modes → Ultra mode

This mode turns off background activity, limits processor performance and reduces screen resolution.

For more fine-tuning, we use the engineering menu (works on the MIUI 14/15):

1. Open the Phone app and type ##4636##.
2. Go to the section Information about the battery.
3. Click on the three dots in the top right corner and select Battery Settings.
4. Activate the option to limit background processes and set a limit on 2-3 process.

Another powerful tool is to disable Xiaomi microservices that work in the background:

Settings → Applications → Application Management → Three Points → Show all processes

You need to manually stop (do not delete!) the following services:

• com.miui.analytics (collection of statistics)
• com.xiaomi.midrop (Fast File Transfer Feature)
• com.miui.cloudservice (cloud backup)
• com.miui.hybrid (hybrid notifications)

3. Optimization for games: how to extend screen time in the PUBG, Genshin Impact and other projects

Games are the main charge eater on Xiaomi. For example, Genshin Impact discharges Redmi at maximum settings. K60 Pro. 2-2.5 hourly PUBG Mobile, for 3-4 To increase screen time, you have to sacrifice graphics or use special tools.

First, set up Game Turbo (built-in game mode) MIUI):

Settings → Special features → Game Turbo → Performance settings

Include the following options:

• 🎮 Limit FPS before 30-45 (instead 60+)
• 🔋 Energy saving in games (limits background processes)
• 📶 Shut down. 5G (If you play through Wi-Fi)
• 🔊 Turn off vibration (saves) ~3-5% charge)

For advanced users, there is a way to forcefully reduce the screen resolution in games through ADB:

adb shell wm size 1600x720

This team will establish a permit. 1600×720 (standard 2400×1080), lighten GPU and increase screen time by 20-30%. The original permission can be returned by the team:

adb shell wm size reset

If the game supports graphics settings, select:

• Shadows: Low or off
• Effects: Average
• Permission: 720p (if available)
• Anti-Aliasing: Disconnected

Hardware modifications: battery replacement and cooling

If software methods don't add enough, you should consider hardware improvements, and the most obvious option is to replace the battery with a larger model. 12 Pro+ You can install the battery 5500 mAh instead of standard 5000 What's the deal? +10-15% screen-time.

The second thing is cooling, and overheating the forced causes the processor to lower the frequency (thermal throttling), which leads to increased power consumption.

• 🧊 Use a cooling case (e.g. Black Shark Cooling Backclip 2 Pro).
• 🔥 Replace the thermopaste on the processor (relevant for devices older than 2 years).
• 📱 Disable wireless charging (it heats the battery stronger than wired).

For owners of flagships (Xiaomi) 13T, Mix Fold 3) There's a radical method, which is to turn off some of the cores of the processor through the Kernel Adiutor (requires root rights). Cortex-A510 Snapdragon 8 Gen 2 may extend screen time by 30-40 minutes, but will reduce productivity in the background.

⚠️ Warning: Replacing a battery or thermal paste will void Xiaomi's warranty.If your smartphone is warranty, use only software optimization techniques.

5. Alternative firmware: custom ROM maximum savings

Stock firmware MIUI optimized for the balance between performance and energy efficiency, but not for maximum screen time. ROM (LineageOS, Pixel Experience or Crdroid can give you an increase in the number of 20-40% Removing Xiaomi Background Services and More Aggressive Power Management.

The best firmware for saving charge:

• 📱 LineageOS - minimalist firmware without unnecessary services.
• 🔋 DerpFest – optimized for gaming and long battery life.
• ⚡ Pixel Experience – ported power saving settings from Google Pixel.

The process of installing custom firmware:

1. Unlock the bootloader through the official Xiaomi tool.
2. Install TWRP Recovery for your model.
3. Download firmware and GApps (if you need Google services).
4. Fly through fastboot or TWRP.

Once installed, it is recommended that:

Settings → Battery → Adaptive battery → Enable


Settings → System → Advanced settings → Limit background activity

⚠️ Attention: Custom firmware installation resets all data on the phone. backup through TWRP Xiaomi Cloud before you start, and some features, for example, IR Blaster or NFC) They may not work properly.

💡

Before installing custom firmware, check its compatibility with your model on the forum XDA Developers: Some firmware is optimized for specific processors (e.g. Snapdragon or Mediatek).

6. External batteries and chargers: how to recharge on the go

If you want maximum screen time without interruptions (for example, for streams or long trips), external power supplies become a must-have accessory. However, not all powerbank and charging are equally useful for Xiaomi.

Criteria for the selection of an external battery:

• 🔌 Power: minimum 20W (fast-charging during games).
• 🔋 Capacity: 20,000 mAh and higher for a full day of use.
• 🔄 Technology: Quick Charge 4 support+ or PD 3.0.
• 📱 Compatibility: Check if it works with Xiaomi HyperCharge (for models with support) 120W).

The best options for Xiaomi in 2026:

To charge during the game, use:

• 🔌 A gaming docking station (like Redmagic Cooling Dock) that recharges the phone and cools it at the same time.
• 🎮 Charging cable with ferrite filter (reduces heating at high currents).

💡

Use external batteries with Quick Charge 4 support+ or PD 3.0 to charge faster than battery consumption during games.

7. Monitoring and Flow Analysis: How to Find "Voracious" Apps

To effectively increase screen time, you need to know exactly what is draining the battery. MIUI There are built-in analysis tools, but they don't show the full picture".

First, check the standard statistics:

Settings → Battery and Performance → Battery Use

Notice the apps marked "High Flow" or "Background Activity." Typical culprits are:

• 📱 Facebook (even in the background consumes up to 10% of the charge per hour).
• 🎵 Spotify/Yandex Music (constant data transfer).
• 📍 Google Maps/Yandex Navigator (GPS + mobile).
• 🎮 Discord (background voice chats).

For in-depth analysis, use the AccuBattery app (available on Google Play).

If AccuBattery shows that the standby flow rate is above 0.5% per hour, then there is a background process in the system that needs to be turned off.

1. Go to Settings. → Annexes → Permits → Autostart and disable autostart for all unnecessary apps.
2. B Settings → Battery → Application Battery Management Select "Limited" Mode for Problem Applications".
3. Install Greenify (requires root) for forced hibernation of background processes.

💡

If AccuBattery shows battery health is below 80%, consider replacing the battery – this could bring back up to 30% of screen time.
