Power Saving Mode on Huawei devices optimizes battery usage by limiting background processes, reducing screen brightness, and disabling non-essential features like 5G and location services. This mode extends battery life during critical times, such as low charge or extended use, without fully restricting core functionalities like calls and messages.

Which Huawei Models Support Customizable Power Saving Settings?
Most Huawei models running EMUI 8.0 or later, including the P30, Mate 40, Nova 9, and P50 series, allow users to customize Power Saving Mode settings. Older devices like the P20 or Mate 10 offer basic toggles, while newer models provide granular controls for app restrictions, screen resolution, and network adjustments.
| Model Series | EMUI Version | Customization Features |
|---|---|---|
| P30 Series | EMUI 9.1+ | App restrictions, screen resolution adjustment |
| Mate 40 Series | EMUI 11+ | 5G control, background data limits |
| Nova 9 Series | EMUI 12 | Adaptive brightness curves, GPU throttling |
Newer devices like the Mate 50 and P60 series introduce AI-driven battery optimization, which learns user habits to dynamically adjust power-saving parameters. For example, if you frequently use navigation apps during commute hours, the system will temporarily allow GPS access while restricting other location-based services. This balance ensures critical functions remain available without unnecessary battery drain. Users can also create custom profiles for work, travel, or entertainment scenarios through third-party tools like Huawe’s AppGallery optimization suites.

How to Activate Power Saving Mode in 3 Steps
- Open Settings > Battery.
- Tap Power Saving Mode or Ultra Power Saving Mode.
- Toggle the switch and adjust app-specific restrictions if needed.
For quick access, add the “Power Saving” shortcut to the notification panel via Settings > Notifications > Quick Settings.
What Features Are Disabled in Huawei’s Power Saving Mode?
Power Saving Mode disables:
- Background app refresh
- Auto-sync for emails and cloud services
- High-performance GPU rendering
- Always-on display (on supported models)
- Animations and haptic feedback
Ultra Power Saving Mode further restricts apps to a pre-approved list and switches to a grayscale display.
Why Does Power Saving Mode Limit Performance on Huawei Devices?
Huawei’s Power Saving Mode prioritizes battery efficiency by capping CPU/GPU clock speeds and reducing RAM allocation. This prevents resource-heavy tasks like gaming or video editing but maintains smooth performance for basic tasks. Benchmark tests show a 30-40% performance drop in this mode.
| Task Type | Normal Mode | Power Saving Mode |
|---|---|---|
| Video Playback | 10 hrs | 14 hrs |
| Gaming (60 FPS) | 4.5 hrs | Not Supported |
| Web Browsing | 8 hrs | 11 hrs |
The Kirin chipset’s AI capabilities play a crucial role here. When Power Saving Mode is active, the processor allocates resources based on task priority. For instance, messaging apps receive higher CPU priority than social media platforms. This tiered approach ensures essential functions remain responsive. However, users may notice slower app launches or delayed photo processing in resource-intensive apps like Photoshop Express. To mitigate this, Huawei allows temporary performance boosts for selected apps via the Battery Optimization Exceptions menu.
Can You Schedule Power Saving Mode on Huawei Phones?
Yes. On EMUI 12 or later:
- Go to Battery > Power Saving Mode.
- Select Scheduled Power Saving.
- Set start/end times or enable “Activate at low battery.”
This automation ensures battery preservation during sleep hours or meetings.
How to Whitelist Apps in Ultra Power Saving Mode
- Enable Ultra Power Saving Mode.
- Tap Manage Apps in the mode’s interface.
- Select essential apps (e.g., messaging, navigation) to keep active.
Note: Only 6-8 apps can be whitelisted, varying by model.
How to Troubleshoot Power Saving Mode Activation Issues
If Power Saving Mode fails to enable:
- Check for system updates via Settings > Software Update.
- Reset app preferences: Settings > Apps > Reset App Preferences.
- Boot into Safe Mode to rule out third-party app conflicts.
Persistent issues may require a factory reset or service center visit.
