Screen On Time (SOT) is a key indicator of smartphone autonomy that worries every owner of Xiaomi, Redmi or POCO. Even with powerful batteries of 5000-6000 mAh, users often find that the screen goes out after 4-6 hours of active use, although the characteristics should last longer. The problem lies not only in battery capacity, but also in the optimization of MIUI, background processes and hardware features.
In this article, we’ll break down 10 working methods to increase SOT by 20-50% without sacrificing functionality. From hidden MIUI settings to hardware constraints, you’ll learn why your Xiaomi 13 Pro runs faster than a Redmi Note 12 with a smaller battery, and how to fix it. All recommendations are tested on current versions of MIUI 14/15 and adapted for different models – from budget POCO M6 to flagship Xiaomi 14 Ultra.
Spoiler: On some Xiaomi models, screen time is artificially limited by the manufacturer through the throttling settings, and you can turn it off without rooting. But that's all in order.
1.Diagnostics: Why does the screen go out quickly?
Before you optimize, you need to understand the root of the problem. At Xiaomi, screen life depends on three key factors:
- 🔋 Hardware limitations: battery capacity, screen type (AMOLED vs LCD), processor (Snapdragon vs MediaTek) and cooling system.
- ⚙️ Program settings: background activity of applications, screen refresh rate, adaptive brightness and energy saving modes MIUI.
- 📱 User habits: games, video streaming, use 5G/4G geolocation.
To identify the weak link, check the battery consumption statistics:
- Go to Settings → Battery and Performance → Battery Use.
- Click on the consumption chart and select the "Last Charging" period.
- Look for applications that consume >10% of the charge and system processes (e.g., Android System or MIUI Daemon).
If you see a screen in the top of your consumption (30-50%), it's a problem with the display settings, if Android System or Google Play Services are to blame for background processes, and if the battery sits evenly without obvious "eaters", it's hardware limitations (for example, a worn-out battery or overheating).
2. Optimize MIUI settings for maximum SOT
MIUI offers a variety of hidden and explicit tools to increase screen time, starting with the most effective:
Energy saving modes
MIUI has three levels of energy saving, but most users only use Battery or Balanced, while Super Power Saving can increase SOT by 15-20%, but with limitations:
- 📵 Disables background synchronization (mail, messengers are updated only when opened).
- 🔄 Limits the frequency of screen updates to 60 Hz (even if you have one) 120/144 Hz).
- 📶 Puts the mobile network in mode 3G (if available).
How to turn on:
- Open Settings → Battery and Performance → Battery Modes
- Choose Super Power Saving and set up exceptions for critical applications (like Telegram or WhatsApp).
💡
MIUI 15 has a hidden mode called "Ultra Battery Saver", which disables all background processes except calls and SMS. To activate it, enter the phone application code ##4636##, then select "Battery Information" → "Ultra-saving mode".
Screen settings: brightness, frequency, timeout
The display is the main consumer of energy.
- 🌞 Adaptive Brightness: Turn it off and set the brightness manually to 40–60%. MIUI It often overstates brightness for comfort, which eats 10-15% of the charge.
- 🔄 Frequency of Update: If you have 120/144 Hz, switch to the next one. 60 Hz in Settings → Display. → Frequency update. The difference in smoothness is minimal, and the gain is minimal. SOT — before 25%.
- ⏱️ Screen timeout: Set 15–30 seconds in Settings → Display. → Sleep after.
Turn off adaptive brightness |Set brightness 40-60% |Switch to 60 Hz (if available) |Reduce timeout to 15-30 seconds |Switch off Always On Display (AOD)
-->
For AMOLED-screens (Xiaomi 13, POCO F5) additionally:
- 🎨 Use dark themes and wallpaper (black pixels are not illuminated, saving charge).
- 🚫 Turn off Always on Display (AOD) In Settings → Display. → Locking the screen – it eats up to 5% of the charge per night.
3.Background processes: how to stop the "invisible eaters" of the battery
MIUI is known for aggressive optimization of background processes, but sometimes it works against the user. For example, Google Play Services or Mi Push Service can consume up to 20% of the charge per day, even if you do not use the corresponding features.
To limit background activity:
- 🛑 Autostart Limitation: Go to Settings → Annexes → Application management → Autostart. Turn off autostart for all applications except instant messengers and email.
Limitation of background activity
- In the same menu, select Permissions → Background activity.
- Leave only critical apps (such as WhatsApp or 2GIS) enabled.
For advanced users:
- 📊 Use it. ADB, To disable unnecessary system services, for example, the command: adb shell pm disable-user --user 0 com.miui.analytics will disable analytics collection MIUI (saves up 3% day-load).
Decision:
- 🔧 For Snapdragon processors: Disable Thermal Engine via ADB: adb shell settings put global thermal_engine_disabled 1 On some models (e.g. Xiaomi) 12T) It increases SOT on 20–30%, It can cause overheating during long periods of time.
- ❄️ Use a cooling case or fan (such as Black Shark FunCooler Pro).
5. Alternative firmware: should you switch to caste?
If all methods have been tried and SOT remains low, some users are considering switching to custom firmware like LineageOS or Pixel Experience.
- ⚡ Pure Android without background processes MIUI.
- 🔧 More flexible energy saving settings.
- 📈 In some models, the increase SOT It is 40% (for example, the POCO X3 Pro with ArrowOS).
Cons:
- 🚫 Loss of warranty (if the phone is under warranty).
- 🔧 Installation difficulty (requires unlocking the bootloader and root rights).
- 📱 Possible camera bugs, NFC or sensors (depending on the model).
