How to Fix Xiaomi Phone Showing Wrong Battery Percentage

Xiaomi HyperOS notification not showing is usually caused by blocked app alerts, battery restrictions, lock screen settings, or Notification shade glitches. The fastest fix is to re-enable app notifications, allow background activity, disable aggressive battery saving for affected apps, and restart the device after clearing System UI or Security app cache.

Steps

Open Settings > Notifications & status bar > App notifications and enable notifications for the affected app. Check alert types like lock screen, floating, badges, and sound.
Open Settings > Apps > Manage apps, select the affected app, and enable Autostart if available. Then open Battery saver for the app and set it to No restrictions.
Open Settings > Notifications & status bar and verify that Lock screen notifications, Notification shade, and status bar icons are enabled. A notification bar issue can hide alerts even when the app is allowed.
Clear temporary system glitches by going to Settings > Apps > Manage apps > Show system apps, then clear cache for System UI or the Security app if available. Restart the phone after clearing cache.
Check for a HyperOS update in Settings > About phone > HyperOS version. Some xiaomi notifications not showing problems are tied to early software builds and are fixed by updates.

Common Issues and Fixes

Notifications arrive only after opening the app — Likely cause: background activity is restricted. Fix: set the app battery mode to No restrictions and enable autostart.
No lock screen alerts — Likely cause: lock screen notification display is disabled. Fix: enable lock screen notifications in system settings and inside the app’s notification categories.
Notification sound works but nothing appears in the shade — Likely cause: notification bar issue or disabled status icons. Fix: enable status bar icons and restart after clearing System UI cache.
Only one app is affected — Likely cause: app-specific channel settings are turned off. Fix: open the app notification categories and re-enable message, call, or alert channels individually.
Notifications stopped after Battery Saver was enabled — Likely cause: HyperOS power management suspended background sync. Fix: disable Battery Saver temporarily and retest the app.

Quick Tips

Data saver can interfere with alerts Messaging apps may still fail under Data saver or restricted mobile data. Check app data permissions if fix notification HyperOS steps do not work.
Do Not Disturb may hide visual alerts Do Not Disturb can hide visual alerts while still allowing vibration or sound. Review DND exceptions and schedule settings.
Cleaner or security apps may suppress notifications Some third-party cleaner or security tools can suppress background alerts. Disable cleanup automation for affected apps.
Restored apps may have broken categories After restoring an app from backup, notification categories may reset incorrectly. Reopen the app once and review notification permissions again.

🤔Note:

If notifications still fail after these steps, test the affected app on Wi-Fi and mobile data, and confirm that background data, battery settings, and notification categories are all enabled at both the system and app level.

Why are Xiaomi notifications delayed on HyperOS?

Delayed alerts usually come from battery optimization, restricted background data, or disabled autostart. Setting the app to No restrictions resolves most delays.

Why is the Xiaomi notification bar not showing icons?

Status bar icons may be disabled in HyperOS settings, or System UI may be stuck after an update. Re-enable status icons, clear System UI cache if possible, and restart the device.

💡Protip:

Before major HyperOS updates or resets, keeping a local backup of app data, photos, and messages helps avoid notification-related setup loss. For device-level backup or file export, a phone manager such as Dr.Fone can be useful.
