Owners of Xiaomi, Redmi and Poco smartphones often face the problem of fast battery discharge when using the screen. 14 Ultra or Redmi Note 13 Pro+ lose 20-30% And the reason for this is that we're not always charging per hour when we're watching video or playing games, and budget devices are running out even faster, and it's not always because of a weak battery, because often unoptimized settings are to blame. MIUI, background processes or hardware limitations.
In this article, we will discuss 7 working ways to increase screen time (SoT – Screen-on Time) on any Xiaomi smartphone, from basic settings to hidden firmware functions. You will learn how to disable unnecessary services, configure the CPU core, use power saving modes without losing performance, and even modify system files (for advanced users). MIUI 14/15 hyperos (2026 year).
Important: results depend on the smartphone model, the firmware version and individual usage conditions. F5 Snapdragon-powered 7+ Gen 2 and AMOLED-The screen can be achieved with the right settings 10-12 SoT hours, while on Redmi 12 helio G88 and IPS-The panel is really just squeezing 6-8 hours.
1. Optimization of screen settings: brightness, refresh rate and technology
The screen is the main consumer of energy in a smartphone. AMOLED-Matrices (e.g. Xiaomi) 13T or Redmi K60) You can save up to 30 percent of your charge by adjusting the brightness and color palette correctly. IPS (Like Redmi. 12C) The effect will be less, but also noticeable.
The first thing you need to do is turn off the adaptive brightness. Algorithms. MIUI They often overstate brightness without needing to eat up charge. Go to: Settings → Display. → Brightness and turn off the adaptive brightness slider. Set a fixed value at the level 30-40% — This is enough for comfortable use in the room.
Next, check the screen refresh rate. On most modern Xiaomi, it is 120 Hz by default, but for everyday tasks (messengers, social networks) 60 Hz will suffice. → Display. → Screen refresh rate on models with LTPO-displays (for example, Xiaomi 13 Pro) the frequency automatically decreases to 1 Hz in static scenes, but this does not always work – it is better to force 60 Hz.
For AMOLED-It is also useful to enable a dark theme and activate the option "Always use dark background" in: → Display. → Dark subject. → Additionally.
This will reduce the load on the pixels and prolong the working time.
- 🔆 Brightness: 30-40% (fixed), adaptive brightness - turn off
- 🔄 Upgrade frequency: 60 Hz for everyday tasks, 120 Hz for gaming only
- 🌑 Dark subject: turn on + Forced dark background for all applications
- ⏱️ Screen timeout: Reduce to 15-30 seconds (in Settings) → Display. → Sleep after)
💡
On smartphones with AMOLED-screens (Xiaomi) 13/14, Poco F5) Turn on the “Read” mode in the display settings – it turns off blue light and reduces power consumption on the screen. 10-15%.
Battery setting: energy saving modes and background limitation
MIUI It offers several energy saving modes, but by default they are either too aggressive (constraining performance) or useless.
First check the status of the battery: Settings → Battery → Battery status
If the capacity is below 80%, the screen time is unlikely to be significantly increased - you will need to replace the battery.
Settings → Battery → Battery modes
Select “Balanced” (not “High Performance”!).
Next, limit the background activity of apps. Many instant messengers and social networks (such as Telegram or TikTok) continue to work in the background even when you are not using them.
- Go to Settings → Applications → Application Management
- Select an app (such as Facebook) → Battery limitations
- Set “Limited” or “Optimized” (for critical apps like WhatsApp, leave “No Limits”)
For maximum savings, activate Super Power Saving manually (in the notification curtain), but note that this will turn off background synchronization and notifications.

3. Disabling unnecessary functions and services MIUI
Xiaomi is known for clogging firmware with unnecessary services that run in the background and consume charge. For example, Mi Cloud, location services, auto-weather updates or advertising push notifications can eat up to the point. 5-10% battery.
The first thing to disable is automatic sync of Mi Cloud. Go to: Settings → Xiaomi account → Mi Cloud → Synchronization
Turn off all unnecessary options (contacts, notes, gallery) if you don't use the Xiaomi cloud, you can completely unplug your account.
Next, check the geolocation. Many applications (e.g. Google Maps or Yandex.Maps) request location even when not in use. Disable geodata for unnecessary applications in: Settings → Confidentiality → Permits → Location
Only allow access to navigation and banking applications.
Another hidden battery eater is Google Play. Open: Settings → Google → Google Play Services → Location update
and turn off Device Search and Improve Location Accuracy if you do not use Find Device.
- ☁️ Mi Cloud: Disable auto sync or delete your account
- 📍 Geolocation: Leave only for critical applications
- 🔍 Google Services: Turn off unnecessary tracking
- 📢 Push notifications: Turn off ads in Settings → Notifications → Promotional notices

4. Processor and graphics optimization: hidden settings MIUI
The processor and the graphics accelerator are the second most power-efficient components after the screen. MIUI there are hidden settings that allow you to limit the maximum frequency of cores or switch to an energy-efficient mode of operation GPU.
To start, check the current performance settings. Go to: Settings → The phone. → Version. MIUI
and press "Kerole" 7 times (you're a developer message) and open it.
Settings → Additional → Developer Parameters
and find the following options:
- "Limit background processes – set the maximum 2-3 process.
"Inactive Apps" - select "Limit everything".
- "Window/Switching Animation – Install 0.5x (speed up work and reduce the load on GPU).
For advanced users, settings are available CPU Governor: CPU frequency control. In the same developer settings, find: Select configuration MIUI → Local special functions → Performance mode
Here you can choose:
- "Battery: Maximum energy saving (limits frequency) CPU before 60-70%).
“Balanced” is the best option for most tasks.
Performance – only for games or benchmarks.
On some models (e.g. Poco) F4 GT Black Shark – Game mode with manual settings available GPU. To activate it, run any game, swipe from the top right corner of the screen and select Performance" → "Setting up GPU". Install energy saving for everyday tasks.
| Setting up | Recommended value | The effect |
|---|---|---|
| Limitation of background processes | 2-3 process | Reduced RAM consumption and CPU on 15-20% |
| Window animation | 0.5x or off | Less stress on GPU, faster |
| Performance mode CPU | "Battery" or "Balanced" | Saving up to 25% on simple tasks |
| Setting up GPU play | "Energy saving" | Extension of the game time by 30-40 minute |
💡
On smartphones with Qualcomm processors (Snapdragon), turn on the option “Limit heat” in the developer’s parameters – this will automatically reduce the frequency. CPU when heated, saving charge.
5.Application Management: What Really Drains the Battery
Not all apps are equally harmful to the battery, according to Xiaomi’s lab, the most energy-consuming applications are:
- Social media (TikTok, Instagram, Facebook) – up to 15% charge per hour due to background activity and autoplay of video.
- Messengers (Telegram, WhatsApp) — 5-8% hourly with active use of chats with gifs and voice messages.
- Navigators (Google Maps, Yandex.Navigator) — 20-25% hourly GPS screen.
- Games (Genshin Impact, PUBG Mobile) — 30-40% per hour at maximum settings of the schedule.
To reduce the cost, follow these rules:
- 📱 Social media: use Lite versions of apps (such as Facebook Lite or Messenger Lite.
- 🗺️ Navigators: download maps offline and turn off 3D-In Google Maps, activate the Battery Saving mode".
- 🎮 Games: reduce the quality of graphics to "Middle" and limit FPS before 30-40 frame/s.
- 🔄 Updates: Turn off auto-update apps in the Play Market (in settings) → "Auto-update of applications" → "Never").
To analyze battery consumption by application, use built-in monitoring: Settings → Battery → Battery utilization
This is a display of the top consumers in the last 24 hours, and if an app is running more than 10 percent, check its settings or uninstall it.
⚠️ Attention: Apps with constant background activity (such as Viber or Zoom) can block the phone from going into deep sleep mode. To fix this, add them to the "Exclusion List" in the battery settings, but limit background activity.
Advanced methods: ADB-commands and firmware modification
If the standard settings do not help, you can use ADB-This method requires connecting a smartphone to a PC and basic command line knowledge.
First, turn on the debugging. USB In the developer settings (see section 4), then connect the phone to the computer and execute the following commands at the terminal (or PowerShell:
adb shell settings put global hidden_api_policy 1
adb shell settings put global captive_portal_detection_enabled 0
adb shell settings put global wifi_scan_throttle_enabled 1
adb shell settings put global location_mode 0These teams:
- Shutting down the hidden ones. API, which can use applications for background activity.
Turn off the check of the captive portal (saves traffic and battery when connecting to Wi-Fi).
Limit the scanning of Wi-Fi networks in the background.
- Completely disable geolocation at the system level.
For users with unlocked bootloader and custom firmware (for example, LineageOS or Pixel Experience), additional tweaks are available:
- Supported kernel installation EAS (Energy-Aware Scheduling for better energy management.
- Using the Magisk module with Power Efficiency settings (e.g. PowerHintManager).
Replace the standard I/O scheduler with bfq or cfq to reduce the processor load.
⚠️ Attention: Misuse of the right ADB-Commands or firmware modification can lead to loss of warranty, malfunction of the phone or even "brick" (impossibility to turn on). → Additionally. → Backup and reset.
Hardware methods: battery replacement and cooling
If software methods fail, the problem could be in the physical state of the battery or overheating. Xiaomi batteries lose 20-30% post-capacity 500 charging cycles (about) 1.5-2 Check the current capacity through the AccuBattery app (available on the Play Market). 80%, Replacing the battery can increase the screen time 30-50%.
Another common problem is overheating, overheating, over 40.°C battery controller automatically limits charge and discharge, which reduces the running time:
- 🔥 Do not use your phone while charging (especially for games or videos).
- 🧊 Remove the case under heavy load (for example, during games).
- 🌡️ Avoid direct sunlight (do not leave your phone on a torpedo in your car).
- 🔄 Clean the dust charger connector regularly (use a wooden toothpick).
For battery replacement, only contact authorized Xiaomi service centers.The cost of the original battery for flagships (for example, Xiaomi) 13 Pro) — 3 000-5 000 RUB, for budget models (Redmi) 12) — 1 500-2 500 Low-quality analogues can swell or damage the fee.
If you're confident in your skills, you can replace the battery yourself.
- Purchase an original battery (e.g., labeled) BM4X Xiaomi 11T Pro).
- Buy a set of screwdrivers and a screen-suction cup.
Follow the guide on YouTube (e.g., the Xiaomi Repair channel).
⚠️ Warning: If you replace the battery yourself, there is a risk of damaging the screen plumes or the camera. If the phone does not turn on after replacing, check the connection of the battery connector and the power supply plume to the motherboard.
