Push Settings
Android manufacturers each add their own battery saver on top of the system one, and every layer can cut BlueMail off from the network and delay your mail. Find your make below for the settings that matter — or start with the generic guide if it is not listed.

ASUS
ZenUI keeps an auto-start manager in Mobile Manager alongside Android's battery optimisation. BlueMail needs clearing in both.
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.
Sony Xperia
STAMINA mode and Sony's battery care both cut background data. Exempt BlueMail from battery optimisation and check STAMINA is off.
vivo, iQOO
Funtouch OS and OriginOS need autostart on and BlueMail allowed under high background power consumption.
Xiaomi, Redmi, POCO
HyperOS and MIUI need autostart enabled and battery saver set to no restrictions, or BlueMail is closed as soon as the screen goes off.
Any Android phone
The four settings that delay mail on every Android device: battery optimisation, Adaptive Battery, background data limits and the notification permission.
