WhatsApp for Xiaomi 11T

MIUI's aggressive battery management freezes WhatsApp in the background, which is the usual cause on the 11T. Go to Settings > Apps > Manage apps > WhatsApp, tap "Battery saver" and set it to "No restrictions," then enable "Autostart" on the same screen. This lets WhatsApp stay alive in the background so messages arrive in real time instead of only when you open the app. See how others solved this on Reddit

On Android each notification channel keeps its own sound, so changing it inside WhatsApp alone often does nothing. Go to Settings > Apps > Manage apps > WhatsApp > Notifications, open the "Messages" channel, and set the Sound there; also make sure "Float notifications" and "Show notification dot" are enabled for that channel. Finally confirm Do Not Disturb isn't active under Settings > Sound & vibration. See how others solved this on Reddit

Incoming calls won't light up the display unless WhatsApp can run in the background and draw over the lock screen. In Settings > Apps > Manage apps > WhatsApp > Other permissions, enable "Display pop-up windows while running in the background" and "Show on Lock screen," then set Battery saver to "No restrictions." Locking WhatsApp in Recents (swipe up to recents, pull the app card down, tap the lock icon) also stops MIUI from freezing it. See how others solved this on Reddit

Use WhatsApp's official "Move to Android" tool, which needs a USB-C to Lightning cable and a factory-fresh or freshly reset 11T. During the 11T's initial setup, scan the QR code that WhatsApp shows on the iPhone, keep both phones connected by the cable, and your chats and media copy over. The iPhone's WhatsApp must use the same phone number you'll verify on the 11T. See how others solved this on Reddit

By default WhatsApp media is kept private so it won't show in Gallery. Open WhatsApp > Settings > Chats and turn on "Media visibility" (and for an individual chat, Chat options > Media visibility), which tells Android's media scanner to index the WhatsApp Images folder. If the folder still doesn't appear, reboot the 11T to force a re-scan. Older media saved while the setting was off can be made visible by deleting any ".nomedia" file inside the WhatsApp media folders using the Mi File Manager app. See how others solved this on Reddit

Choppy or robotic WhatsApp calls on the 11T usually trace back to MIUI throttling the app or a weak data connection rather than the hardware. Set WhatsApp's Battery saver to "No restrictions" under Settings > Apps > Manage apps > WhatsApp, and turn off Data Saver under Settings > Connection & sharing (and "Use less data for calls" inside WhatsApp > Settings > Storage and data). If it persists, disable any VPN and test on a different Wi-Fi network to rule out router-side packet loss. See how others solved this on Reddit
