When you're using the device with external monitor, you are probably doing things like watching a movie or browsing the net through wifi or 3G network, which drain the battery.
It would be great to be able to plug the device to the monitor, do what ever you want, and leave with a fully charged battery.
Just to be clear - this is a hardware proposal to future devices.

HDMI supplies a minimum of 55mA current on the 5V line, but most source devices on the market today provide significantly more current on the 5V line than the HDMI specification requires. (http://www.hdmi.org/learningcenter/kb.aspx?c=13#42)
Use this current to charge the battery while the HDMI is connected.
The idea is, that when you plug your future device (with HDMI) to a monitor, you don't have to get a separate charger to keep the device juiced up, but it will charge itself from the HDMI connection instead.
