Short answer: Android may delay background work to protect battery. App-specific restrictions, Data Saver, an unstable push connection, or manufacturer power tools can make the delay more noticeable.
This guide uses low-risk checks first, keeps account and personal data protected, and helps you identify whether the problem belongs to the device, app, network, or service.
What usually causes this problem
Allow notifications and background activity for the affected app, remove extreme battery restrictions, and test with Battery Saver off. Common causes include:
- The app is battery restricted.
- Background data is blocked.
- Battery Saver is always on.
- The app was put into deep sleep.
Change one thing at a time. If several settings are changed together, it becomes difficult to know which step actually solved the problem or created a new one.
Fix it in the safest order
- Check the app notification categories. Complete the check, then test the original symptom before moving to the next step.
- Allow background data. Complete the check, then test the original symptom before moving to the next step.
- Set battery use to optimised or unrestricted for critical apps. Complete the check, then test the original symptom before moving to the next step.
- Update the app and Android. Complete the check, then test the original symptom before moving to the next step.
- Restart the phone. Complete the check, then test the original symptom before moving to the next step.
- Send a test message while the screen is off. Complete the check, then test the original symptom before moving to the next step.
Protect your data while troubleshooting
Do not disable battery protection for every app; change only services that need timely alerts. Back up irreplaceable files before clearing storage, resetting settings, removing an account, reinstalling an app, or formatting a drive. Use official apps and support pages rather than download links sent through pop-ups, comments, or unexpected messages.
For users in the Philippines, also check whether the issue changes between home Wi-Fi and mobile data. Prepaid balance, carrier maintenance, local power interruptions, and ISP outages can resemble a device problem. Avoid repeated resets when the service itself is unavailable.
How to confirm the fix
A test message arrives with the screen locked and the setting survives a restart. Repeat the test after one normal restart. A workaround that succeeds once but fails immediately after reboot is not a complete fix.
When to get official help
Contact the app provider if only that service remains delayed on several networks. Before contacting support, note the device model, operating-system version, app version, exact error text, time of failure, and the steps already tested. Never send a password, one-time code, recovery phrase, or full payment-card number.
