What is the Xiaomi Smart Kettle 2 Pro feature of keep warm after pick-up?

When you lift the kettle in the keep warm state, the screen display will show “--”. If you put it back to the base within 3 minutes, the kettle will continue to keep warm. If you put it back to the base for more than 3 minutes, the kettle will exit the keep warm mode and return to the standby state.
Note:
1. The keep warm after pick-up is off by default, and you can open it on the Mi Home app;
2. If you enable the keep warm after pick-up, and remove the kettle from the base while the kettle is in keep-warm mode, the kettle will return to keep-warm mode, so please make sure the amount of water in the kettle can not be lower than the minimum water level line. Otherwise, it will continue to heat and cause the risk of dry-burning;
3. If you add cold water in the middle, the keep warm after pick-up will be turned off.
