Fix BlueMail push notifications on ASUS
Published
Menu names differ between software versions. If a path here does not match your phone, search your Settings app for the setting named in bold — it is the same setting under a different label.
ASUS ships a Mobile Manager app that maintains its own list of apps allowed to start on their own. Android’s battery settings do not override it, so both need setting.
Allow auto-start
Open Mobile Manager → Auto-start manager (on some builds, Settings → Battery → Auto-start manager) and allow BlueMail.
Without this, BlueMail does not come back after a reboot or after the system closes it to free memory.
Set BlueMail to unrestricted
Settings → Apps → BlueMail → Battery → Unrestricted, or on older ZenUI builds Settings → Battery → Battery optimisation → All apps → BlueMail → Don’t optimise.
Check PowerMaster
If your phone has the PowerMaster screen, look for a battery mode or a “clean up in suspend” option — the more aggressive modes close background apps regardless of the two settings above.
If mail still arrives late
- Lock BlueMail in Recents.
- Check Settings → Notifications → App notifications → BlueMail.
Push Settings for other devices
Google Pixel
Pixels run stock Android, so two settings cover it: set BlueMail's battery usage to unrestricted, and stop Adaptive Battery from demoting it.
Huawei, Honor
Set BlueMail's App launch to manage manually and enable all three switches — auto-launch, secondary launch and run in background.
Motorola
Motorola runs close to stock Android: set BlueMail's battery usage to unrestricted and turn off Adaptive battery.
OnePlus
OxygenOS adds sleep standby optimisation and deep optimisation on top of battery optimisation. Turn off all three for BlueMail.
Oppo, realme
ColorOS and realme UI need auto start-up, background running and power saver all set for BlueMail before push arrives reliably.
Samsung Galaxy
Samsung stacks three power savers on top of Android's own. Set BlueMail to unrestricted, keep it out of Sleeping apps, and turn off Adaptive battery.
