Modern Xiaomi, Redmi and POCO smartphones are equipped with powerful processors and bright displays, which inevitably leads to high power consumption. Owners often face a situation where by mid-day the charge level drops below what they want, causing concern. System optimization allows you to significantly extend battery life without buying a new device.
The efficiency of Android and the MIUI shell is directly dependent on the number of background processes running. If you don’t control the applications, they continue to consume resources even in a locked state. In this article, we will discuss a comprehensive approach to energy saving that will help you forget to find an outlet at the most inopportune time.
Analysis of energy consumers in MIUI
The first step is always to audit the current state. Xiaomi provides detailed statistics to identify “gluttonous” applications. Often it turns out that the main discharge is not caused by telephony or SMS, but by social networks or navigators running in the background.
To get accurate information, you need to go to settings. The path to the section is usually: Settings → Battery and performance. Here you will see the flow chart for the last 24 hours or 7 days. Data visualization helps you quickly understand which program consumes the most resources.
- 📊 The screen is usually the most important consumer of energy, especially at high brightness and refresh rate.
- 📱 Apps – programs you actively use or those hidden in the background.
- 📡 Mobile network – discharge in areas with poor coverage, where the phone is constantly looking for a signal.
- 🔋 Waiting – consumption in idle mode, which should not be too high.
Note the setting Background activity. If the application you didn't use wasted 10-15% In such cases, it is worth considering the possibility of removing the program or limiting its rights.
Optimization of screen and interface settings
The display is the face of a smartphone and at the same time its most energy-intensive part. AMOLED technology, used in Xiaomi’s flagship models, saves energy when displaying black. Turning on a dark theme is not just an aesthetic solution, but a real way to reduce consumption.
The refresh rate of the image also plays a critical role. Modern screens support 90 Hz, 120 Hz and even 140 Hz. Smooth animation looks beautiful, but requires double or triple the work of the GPU. To save charge, it makes sense to switch to the standard 60 Hz.
☑️ Screen optimization
Don't forget to time out the screen. If the device stays on in your pocket after use, the battery is wasted. Set a value of 30 seconds or 1 minute in the Settings menu → Screen and brightness → Sleep mode.
⚠️ Attention: Automatic brightness may not work properly when using darkened protective glasses. In such cases, it is better to set the backlight level manually to avoid unnecessary consumption.
Management of Background Processes and Applications
MIUI aggressively manages memory, but some applications have learned to bypass these limitations: they can constantly update content, track geolocation or synchronize data, and controlling background activity is key to extending battery life.
You can set individual limits for each application you install. Go to Settings → Applications → Application Management, select the program you want, and find Saving Charge. There are three modes available.
| Mode of work | Description of behaviour | Recommendation |
|---|---|---|
| No restrictions. | The application works in the background without restrictions | Only for messengers. |
| Saving charge | Limits background activity | For most programs |
| Savings are hard | Prohibits working in the background completely | For rarely used games |
Also, you should disable auto-update apps via mobile network. Go to the Google Play Store, open settings and select App Auto-Update → Only via Wi-Fi. This will prevent sudden discharge when downloading updates on the way.

Configuring network modules and connections
Networking is one of the most energy-intensive processes for any smartphone, and if you're in a sensitive area (such as in the subway or outside the city), the communication module is running at its limit, and the stability of the connection has a direct impact on autonomy.
Use of technology 5G It's not yet optimized perfectly, and it can quickly land the battery, even if you're not using high speed. 5G, It is better to switch to mode Preferably LTE via the Settings menu → SIM-maps and mobile networks.
- 📍 Geolocation - turn off GPS, When not needed, or use the "Only by network coordinates" mode".
- 🔵 Bluetooth – Turn off the module if you don’t wear headphones or watches.
- 📶 NFC — Contactless payment module should not be active continuously.
The Wi-Fi Assistant feature in Xiaomi phones can continuously scan available networks even if Wi-Fi is turned off. This is for fast connectivity but consumes charge. Turn off this option in advanced Wi-Fi settings.
⚠️ Warning: Constant search for Wi-Fi networks in the background can drain your phone overnight 5-7%, Even if the screen was off. Check the settings in the Wi-Fi section.
💡
Use the Battery widget on your desktop for quick access to the power saving mode, faster than going through the deep settings menu every time.
Use of energy saving regimes
Xiaomi has built-in emergency tools. Power saving mode limits background synchronization, reduces CPU clock speed and reduces brightness. The adaptive battery learns your habits and allocates resources smarter.
There's also Ultra Battery Saver, which turns your smartphone into a simple phone caller, and you only get calls, SMS, and contacts, and you can stretch the remaining 10 percent of your charge for hours or even a whole day.
To activate, click on the battery icon in the notification curtain or go to Settings → Battery and Performance. Here you can set the savings to automatically turn on when you reach a certain percentage, for example, 20%.
💡
The adaptive battery in MIUI will eventually remember which apps you rarely use and will begin to restrict their background work more tightly without your involvement.
Charging and battery care rules
The physical condition of the battery deteriorates over time, but proper operation can slow this process. Lithium-ion batteries used in Xiaomi do not like extremes: full discharge to zero and prolonged charging at 100%.
The optimal range for a long battery life is 20 to 80 percent. Try not to keep your phone on the wire all night, although modern charge controllers can stop current. Optimized night charging helps solve this problem software.
Use only original cables and power supplies. Cheap analogues may not support Quick Charge or Power Delivery fast charging protocols, leading to overheating and degradation of battery chemistry.
⚠️ Warning: Overheating is the main enemy of the battery. Do not play heavy games or shoot videos in the battery. 4K during charging, especially fast high power charging.
