If your Xiaomi phone's battery seems to drain faster than it used to, you're not alone. Battery performance naturally degrades over time, especially with heavy use like gaming or video streaming. The good news is there are several effective ways to troubleshoot and fix battery drain issues on your Xiaomi device.
Check Battery Health and Usage
Start by identifying which apps are consuming the most power. Xiaomi devices provide detailed battery usage information that can help you pinpoint the culprits.
To check battery usage:
- Go to Settings > Battery & Performance
- Review the list of apps sorted by power consumption
- Look for apps with unusually high battery usage
For devices running HyperOS, you can also check your battery cycle count to understand your battery's health status. A battery cycle refers to one complete charge from 0% to 100%, and most Xiaomi batteries retain about 80% capacity after 800 charge cycles.
Manage Background Apps
Apps running in the background can significantly drain your battery even when you're not actively using them. Xiaomi's MIUI system includes built-in tools to control background activity.
To restrict background apps:
- Navigate to Settings > Battery & Performance
- Tap "App Battery Saver"
- Choose apps you use less frequently and restrict their background activity
- You can set apps to close after 10 minutes of background activity or restrict them completely
For important apps you need running in the background, use the app pinning feature by dragging the app downward in the recent apps tray to lock it and prevent it from being cleared.
Optimize Display Settings
The screen is one of the biggest battery consumers on any smartphone. These display adjustments can make a significant difference:
Enable Reading Mode (Dark Mode)
- Go to Settings > Display
- Tap Reading Mode and toggle it on
- Dark interfaces use less power, especially on OLED screens
Reduce Screen Resolution
- Navigate to Settings > Display
- Tap Display Resolution
- Select FHD+ instead of higher resolutions
Shorten Screen Timeout
- Go to Settings > Always-on Display & Lock Screen
- Tap Sleep
- Reduce to 30 seconds or 15 seconds
Control Location and Connectivity Services
Location services and wireless connections constantly search for signals, which drains battery life.
Disable WiFi and Bluetooth Scanning
- Go to Settings > Location
- Tap WiFi and Bluetooth Scanning
- Toggle both options off
Manage App Location Access
- Navigate to Settings > Location
- Tap App Access Location
- Review apps under "Allowed All the Time" and change permissions to "Allow While Using" or "Deny"
Turn Off Unused Connections
- Disable mobile data when connected to WiFi
- Turn off Bluetooth when not using headphones or accessories
- Disable GPS when not needed for navigation
System Maintenance and Updates
Regular system maintenance can resolve many battery-related issues.
Reboot Your Device
A simple restart can clear temporary files and stop background processes that may be draining your battery. Hold the power button and select Restart.
Update Software
Software updates often include battery optimizations and bug fixes. Check for updates in Settings > About Phone > System Updates.
Clear System Cache
- Go to Settings > System App Settings > Security
- Select Boost Speed > Clear Cache
- Choose a time interval for automatic cache clearing
Additional Battery Saving Tips
- Enable Power Saving Mode when battery is low by pulling down the notification panel and tapping Battery Saver
- Avoid live wallpapers which constantly animate and consume power
- Delete unused apps that may run background processes
- Keep your phone away from extreme temperatures as heat accelerates battery degradation
- Charge between 20% and 80% to extend overall battery lifespan
- Disable unnecessary app notifications in Settings > Notifications & Control Center > App Notifications
By implementing these strategies, you can significantly improve your Xiaomi phone's battery life and reduce frustrating drain issues. Start with checking battery usage and restricting background apps, then gradually apply the other optimizations based on your usage patterns.
