WhatsApp for Xperia 10 VI

This is a known WhatsApp + Bluetooth issue on Xperia rather than a hardware fault: tapping answer inside the app often works even when the headset's physical button doesn't register the call. Make sure WhatsApp has the Phone and Microphone permissions under Settings > Apps > WhatsApp > Permissions, then re-pair the device under Settings > Device connection > Connection preferences > Bluetooth. Update WhatsApp from the Play Store, since several call-routing bugs have been fixed in newer builds. If a specific car or earbud still fails, toggle Bluetooth off and on right before answering to force the audio to re-route. See how others solved this on Reddit

Xperia phones apply their own audio processing, so first open Settings > Sound & vibration > Audio settings and disable enhancements like Dolby Sound / 360 Upmix that can interfere with call audio. Clear WhatsApp's cache via Settings > Apps > WhatsApp > Storage & cache > Clear cache, and confirm WhatsApp has the Microphone permission under Settings > Apps > WhatsApp > Permissions so calls capture properly. If voice notes or call audio still drop, disconnect any paired Bluetooth device, since the Xperia can route WhatsApp audio to it silently. See how others solved this on Reddit

Yes — modern WhatsApp has a built-in second account: open WhatsApp, tap the three-dot menu, go to Settings, tap the arrow next to your name at the top, and choose Add account (you'll need a second number to verify). Both accounts then live in the same app and you switch between them from that menu. If you'd rather keep them fully separate, the Xperia 10 VI does not include a native app-clone feature, so a work profile or a third-party dual-app tool would be the alternative — but the built-in multi-account option is the simplest and most reliable route.

This is almost always Sony's battery management killing WhatsApp in the background: go to Settings > Apps > WhatsApp > App battery usage and set it to Unrestricted, then turn off STAMINA mode under Settings > Battery > STAMINA mode. Also verify notifications are fully enabled under Settings > Apps > WhatsApp > Notifications with the message categories switched on. After changing these, restart the phone so the background restriction is actually lifted. See how others solved this on Reddit

If the mic works in normal phone calls and the voice recorder but not in WhatsApp, the app usually just lacks mic access: open Settings > Apps > WhatsApp > Permissions and make sure Microphone is allowed. Then clear WhatsApp's cache under Settings > Apps > WhatsApp > Storage & cache > Clear cache and update the app from the Play Store. If it only happens during calls with a headset connected, disconnect the Bluetooth device, since the Xperia can route mic input to a paired headset whose microphone isn't working correctly.

Heavy WhatsApp drain usually comes from constant background syncing and media auto-downloads rather than a faulty battery: in WhatsApp go to Settings > Storage and data > Media auto-download and set photos, audio, video and documents to Wi-Fi only, which cuts a lot of wakeups. On the phone side, leave Settings > Apps > WhatsApp > App battery usage set to Unrestricted (restricting it makes WhatsApp re-sync harder and burn more power when reopened). Check Settings > Battery > Battery usage first to confirm WhatsApp is actually the top consumer before changing anything. See how others solved this on Reddit
