WhatsApp for Honor X7b

MagicOS aggressively closes background apps to save battery, which delays WhatsApp messages and notifications. Two settings fix this together. First, go to Settings > Apps > App management > WhatsApp > Battery and set it to 'No restrictions'. Then go to Settings > Battery > App launch, find WhatsApp, switch it from 'Auto-manage' to 'Manage manually', and enable all three toggles: Auto-launch, Secondary launch, and Run in background. This stops the system from suspending WhatsApp when the screen is off. See how others solved this on Reddit

This happens when WhatsApp lacks lock-screen notification permission and is being battery-restricted in the background. Go to Settings > Notifications > WhatsApp, enable 'Allow notifications', and turn on 'Lock screen notifications' and 'Banners'. Within WhatsApp's notification categories, make sure the 'Calls' channel is enabled. Then open Settings > Apps > App management > WhatsApp > Battery and set it to 'No restrictions' so incoming call signals are not blocked while the phone is idle. See how others solved this on Reddit

A proven MagicOS workaround is to lock the app in the recent-apps view so the system won't clear it from memory. Open the recent apps (multitasking) screen, swipe down on the WhatsApp card to pin/lock it (a lock icon appears). Combine this with 'Run in background' enabled under Settings > Battery > App launch > WhatsApp. Keeping WhatsApp pinned prevents the memory manager from terminating it, so push notifications arrive in real time.

When notifications silently stop, a system or app update has usually reset WhatsApp's background and notification permissions. Go to Settings > Notifications > WhatsApp and toggle 'Allow notifications' off and back on, then re-grant 'No restrictions' under Settings > Apps > App management > WhatsApp > Battery. If it persists, clear WhatsApp's cache via Settings > Apps > App management > WhatsApp > Storage (use Clear cache, not Clear data, which deletes chats), then restart the phone so the push service re-registers.

Yes. The Honor X7b ships with Google Mobile Services and the Play Store in most regions, so WhatsApp installs and runs normally, including push notifications, unlike older Huawei-era devices. WhatsApp's push delivery relies on Firebase Cloud Messaging, so as long as Google Play services is installed and kept updated, calls and messages will deliver reliably.

System updates can leave WhatsApp's cached data in a stale state, causing lag, stuck media, or crashes. Go to Settings > Apps > App management > WhatsApp > Storage and tap 'Clear cache' (not Clear data, which deletes chats), then update WhatsApp from the Play Store to the latest version. If problems continue, restart the device so background services reinitialize cleanly. See how others solved this on Reddit
