WhatsApp for Realme Narzo 50 Pro

The Narzo 50 Pro 5G shipped on Realme UI 3.0 (Android 12) and has reached the end of its major OS update cycle, so a fresh Android 14 build isn't coming. WhatsApp still runs fine on Android 12, so this won't stop you using the app. Check Settings > Software update for the final security patches, and keep WhatsApp itself current through the Google Play Store (open the Play Store, search WhatsApp, and tap Update if one is available).

This usually happens when battery optimization or a notification setting stops WhatsApp from waking the display. Go to Settings > Apps > App management > WhatsApp > Battery usage and choose Allow background activity (don't restrict it). Then open Settings > Notifications & status bar > Manage notifications > WhatsApp and turn on Allow notifications plus Lock screen notifications and the Calls category. Finally confirm WhatsApp has Display over other apps permission under Settings > Apps > Special app access > Display over other apps. See how others solved this on Reddit

Slow charging is most often a worn cable or a non-original charger, so use the bundled Realme adapter and a USB-C cable rated for the phone's fast-charge spec, and clear any lint from the port. For call battery drain, open Settings > Battery to confirm WhatsApp is a top consumer, and inside WhatsApp go to Settings > Storage and data and enable Use less data for calls. Lowering screen brightness during long video calls also helps noticeably. See how others solved this on Reddit

Back up first while the phone still works: in WhatsApp tap the three dots > Settings > Chats > Chat backup and run a Google Drive backup (include videos if you want media saved). On the new Android phone, install WhatsApp from the Play Store, verify the same phone number, and tap Restore when prompted, using the same Google account. Moving to an iPhone is different, you'd use WhatsApp's official Move to iOS transfer, because Google Drive backups can't be restored on iOS. See how others solved this on Reddit

It's still safe for everyday WhatsApp use as long as you avoid sideloading modified versions (GB WhatsApp and similar clones), which can get your number banned and put your chats at risk. Stick to the official app from the Google Play Store, install the last security patches under Settings > Software update, and turn on two-step verification in WhatsApp via Settings > Account > Two-step verification to better protect your account on an older device.
