Turn Off Wi-Fi Hotspot Automatically auf Xiaomi
A personal hotspot left running with no connected devices still consumes battery, because Xiaomi phones keep the Wi-Fi radio broadcasting until you switch it off manually. MIUI includes a background function that watches the hotspot connection and shuts it down once no device has used it for a while.
You find the switch under Settings ➤ Portable hotspot ➤ Turn off hotspot automatically. Toggle it on and the phone stops broadcasting the network as soon as the last connected device disconnects, instead of leaving the hotspot open indefinitely.
This setting matters most if you turn on the hotspot for a quick file transfer or to share data with a laptop, then forget about it afterwards. Without automatic shutdown, the hotspot module keeps the antenna active, drains the battery faster and can interfere with other Wi-Fi based background tasks.
Leave the option disabled only if you rely on the hotspot staying available for intermittent connections over long periods, for example a smart display that connects and disconnects throughout the day. In that case, manual control avoids unexpected drops in service.
