WhatsApp for Infinix Note 50

Infinix's XOS power management aggressively freezes background apps, which kills WhatsApp's push connection. Go to Settings > Apps > App management > WhatsApp > Battery and set it to 'No restrictions' (or 'Allow background activity'). Then open the Recents (multitask) screen, find the WhatsApp card and lock it (pull the card down or tap the lock icon) so XOS won't clear it from memory. Finally make sure WhatsApp itself is allowed to run in the background and isn't being put to sleep by any 'Deep sleep' / power-saving feature in Settings > Battery.

The 'too many notifications' warning is an Android system message that appears when an app posts notifications very frequently, after which the system can start silencing them. Open Settings > Notifications & status bar (App notifications) > WhatsApp, make sure 'Allow notifications' and the 'Messages' channel are on, and re-enable banner/lock-screen display if Android turned it off. Then in Settings > Apps > App management > WhatsApp > Battery choose 'No restrictions' so background message sync isn't throttled. See how others solved this on Reddit

This is usually a missing permission or background restriction. Go to Settings > Apps > App management > WhatsApp > Permissions and set Microphone, Camera and Phone to 'Allow', then check Settings > Security & privacy > Permission manager > Microphone to confirm WhatsApp isn't blocked globally. If calls still drop in the background, set WhatsApp's battery option to 'No restrictions' under Settings > Apps > App management > WhatsApp > Battery and turn off any battery-saver mode in Settings > Battery so the call audio stream isn't interrupted.

Infinix ships preloaded apps (Palmstore, hi-services and similar) plus recommendation ads that consume RAM and compete with WhatsApp. Open Settings > Apps > App management, open each unwanted app and tap 'Disable' or 'Uninstall' where the option is available. To cut recommendation ads, open the individual Infinix apps (for example Palmstore or the file/cleaner app) and turn off their 'Recommendations' / 'Receive notifications' toggles in that app's settings. Freeing RAM this way keeps WhatsApp responsive and less likely to be killed under memory pressure. See how others solved this on Reddit

WhatsApp backs up to Google Drive. Open WhatsApp > tap the three dots > Settings > Chats > Chat backup, link the Google account you'll use on the next phone, and tap 'Back up' to push an up-to-date copy. For a local media copy, connect the phone to a computer and copy Internal storage > Android > media > com.whatsapp > WhatsApp. On the new device, install WhatsApp with the same number and sign in to the same Google account when prompted to restore.
