Hi -

> drained within 2 hours...

this is the crux of current WiFi interfaces in mobile phones. WiFi 
consumes way to much power - especially if a phone forwards traffic for 
other devices. It is possible - but the mobile handset will need to have 
the size and weight of a mobile phone 8 years ago, simply to provide the 
battery capacity. Batman-Experimental has an option to disable routing 
traffic for other phones (--asocial-device : mobile device mode 
reluctant to help others). An "asocial" device will just make itself 
known to the existing mesh infrastructure and use the closest Batman 
node as a gateway. It will only reply to Originator messages originated  
by the chosen gateway. Together with a slow OGM interval you can roam 
within an existing mesh infrastructure without wearing your batteries 
out quickly.

That sounds like a miserable design.
