Did your smartphone start draining battery significantly faster after updating to Xiaomi HyperOS or Samsung One UI? You are not alone. Major OS updates frequently introduce uncalibrated power daemons, aggressive background analytics, and unnecessary virtual memory swapping that can drain 15% to 25% of your battery overnight.
Instead of relying on useless "Battery Saver" apps from the Play Store, here are 5 proven, tested system tweaks that will stop background battery drain and noticeably extend your screen-on time in 2026 without rooting your phone.
1. Disable Virtual RAM (RAM Plus / Memory Extension)
Both Xiaomi and Samsung heavily promote "Virtual RAM" (expanding your 8GB RAM to 16GB using internal storage). In reality, flash storage is drastically slower than physical LPDDR5 RAM. Your phone's processor wastes massive battery constantly compressing and swapping data into slow storage.
Turning Virtual RAM OFF eliminates UI micro-stutters and saves up to 10% to 15% daily battery life.
How to Disable on Samsung (One UI):
- Open Settings > Device Care (or Battery and device care).
- Tap Memory > tap RAM Plus.
- Toggle the switch OFF and restart your device.
How to Disable on Xiaomi / POCO / Redmi (HyperOS):
- Open Settings > Additional settings.
- Select Memory extension.
- Choose Off and reboot your smartphone.
2. Turn Off Hidden 24/7 Wi-Fi and Bluetooth Scanning
Even when you toggle Wi-Fi and Bluetooth "OFF" from your quick notification shade, Google Location Services continuously scans nearby wireless networks 24/7 in the background.
- Open Settings > Location.
- Tap Location services.
- Toggle OFF Wi-Fi scanning.
- Toggle OFF Bluetooth scanning.
Your GPS navigation apps (like Google Maps) will continue to work perfectly, but your phone will stop wasting power searching for rogue networks.
3. Kill System Telemetry & Ad Daemon Services
Both manufacturers bundle background services that log usage analytics and feed promotional notifications.
On Xiaomi HyperOS:
- Go to Settings > Fingerprints, face data & screen lock > Authorization & revocation.
- Revoke authorization for msa (MIUI System Ads) and Enhanced system service.
- Navigate to Settings > Privacy > Ad services > Turn OFF Personalized ad recommendations.
On Samsung One UI:
- Go to Settings > Security and privacy > More privacy settings.
- Turn OFF Send diagnostic data.
- Turn OFF Customization Service.
4. Reset "Battery and Performance" Cache (Xiaomi / POCO Specific)
Following a firmware update, Xiaomi devices often experience a bug where the power management profile gets trapped in an infinite CPU loop, causing the device to feel warm even while idle.
- Go to Settings > Apps > Manage apps.
- Tap the 3 dots in the top-right corner and select Show all apps.
- Search for Battery and performance.
- Tap Clear data > Clear all data.
- Reboot your phone.
Note: This resets your battery usage statistics chart and recalculates battery calibration from scratch.
5. Configure "Deep Sleeping Apps" (Samsung One UI Specific)
Samsung includes a powerful battery feature that many users configure incorrectly. Regular "Sleeping apps" still wake up periodically to poll notifications. Deep sleeping apps never run in the background under any circumstances until you manually open them.
- Go to Settings > Battery > Background usage limits.
- Tap Deep sleeping apps.
- Tap the + (Add) button at the top right.
- Add shopping apps (AliExpress, Amazon, Daraz), food delivery apps, and offline games.
🏁 The Bottom Line
By simply disabling Virtual RAM, turning off background radio scanning, and cutting off telemetry, you eliminate the primary culprits behind post-update battery drain. Give your device 24 to 48 hours after applying these tweaks for the battery management profiles to recalibrate—you will see a dramatic improvement in your daily battery endurance.
