Battery Optimization
Settings > Apps > Hedy > Battery
Set to Unrestricted
Make sure Background restriction is not enabled
Lock Hedy in Recent Apps
Open Recent Apps (swipe up and hold from the bottom of your screen)
Find Hedy in the list
Long-press Hedy's preview > tap the Lock icon
Why this matters: Locking Hedy in Recent Apps prevents the system from closing it in the background. This is the single most effective step on most phones.
Important: Some phone manufacturers reset these settings after system updates. If Hedy stops working after an update, re-check the settings below for your phone brand.
Xiaomi / POCO / Redmi
Xiaomi phones (including POCO and Redmi) have some of the most aggressive battery restrictions. You may need to change several settings to keep Hedy running.
1. Set Battery Saver to No Restrictions
Settings > Apps > Manage apps
Find and tap Hedy
Tap Battery saver
Select No restrictions
2. Enable Autostart
Settings > Apps > Manage apps > Hedy
Tap App permissions
Enable Background autostart
On older MIUI versions: Open the Security app > Permissions > Auto-start > enable Hedy.
3. Lock Hedy in Recent Apps
Open Recent Apps
Find Hedy and drag it downwards, or long-press and tap the padlock icon
A lock icon should appear on the app card
Locked apps are protected from being cleared, even when you tap "Clear all."
4. Lock in Boost Speed (Optional)
Open the Security app
Tap Boost speed
Tap the Settings (gear) icon
Tap Lock apps > select Hedy
This provides extra protection against the "Ultra battery saver" feature.
Note: Xiaomi may re-enable battery restrictions after system updates. If Hedy stops working after an update, re-check all the settings above.
Samsung
Samsung requires several settings to prevent Hedy from being put to sleep.
1. Set Hedy to Unrestricted
Settings > Apps > Hedy > Battery
Set to Unrestricted
2. Add to Never Sleeping Apps
Settings > Battery > Background usage limits
Tap Never sleeping apps
Tap + and select Hedy
3. Disable "Put Unused Apps to Sleep"
Settings > Battery > Background usage limits
Disable Put unused apps to sleep
Warning: Even after adding Hedy to "Never sleeping apps," Samsung may move it back to sleep after a firmware update. Re-check this setting after any system update.
4. Disable Auto Optimization
Settings > Battery > More battery settings
Disable Auto optimization (if available)
Disable Adaptive battery
On One UI 7 (Android 15), some of these options may have moved. Look under Settings > Battery and device care > Battery for similar options.
5. Lock in Recent Apps
Open Recent Apps
Long-press Hedy > tap Lock this app
OnePlus
OnePlus phones have severe background limits that can also reset after firmware updates.
1. Disable Battery Optimization
Settings > Apps > (gear icon) > Special Access > Battery Optimization
Switch filter to All apps
Find Hedy > select Don't optimize
2. Disable Advanced Optimization
Settings > Battery > Battery optimization
Tap the three-dot menu > Advanced optimization
Disable Deep optimization (or "Adaptive Battery")
Disable Sleep standby optimization
Deep optimization is the main app killer on OnePlus. Disabling it is critical for Hedy to work properly.
3. Lock in Recent Apps
Open Recent Apps > long-press Hedy > tap Lock
Warning: OnePlus may randomly revert the "Don't optimize" setting. Locking Hedy in Recent Apps helps prevent this.

Settings > Apps > Hedy > Battery
Make sure Background restriction is not enabled
Set battery usage to Unrestricted
Final Checks
Restart your device after making all changes
Start a Hedy session and verify it keeps running with the screen off for 5+ minutes
After any system update, re-check all settings above for your phone brand
Troubleshooting tip: If issues persist, disable any third-party battery saver or "RAM boost" apps. These can conflict with the system settings above. For more device-specific help, visit dontkillmyapp.com.
