The phone's Wi-Fi hotspot is automatically disabled

Problem:

The phone's portable Wi-Fi hotspot is automatically disabled, and a message is displayed in the notification panel indicating that the hotspot is disabled (no devices connected, hotspot has been disabled, or battery life will be extended.).

Cause:

To increase the battery life of your phone, the portable Wi-Fi hotspot will be automatically disabled if no devices are connected to this hotspot within 10 minutes after it has been enabled (for versions earlier than EMUI 9.0, it is 2 minutes; this does not apply to devices running EMUI 9.0 where this duration cannot be changed). This is a new feature in EMUI 8.0 and later versions.

This feature cannot be disabled temporarily. The Wi-Fi hotspot will not be automatically disabled while charging.
