I have an android tablet (1) and phone (2). Using the phone as a wireless hotspot drains the battery almost as fast as having the phone screen on. I'd like to be able to use it as a tethered hotspot and charge the phone from the larger battery in the tablet (3) but I have two problems - micro usb to micro usb cables don't seem to exist and i'm not sure that a micro to usb converter + a micro usb to usb cable is worth setting up - does it do anything useful?
- motorola xoom - answer may be honeycomb specific
- nexus one
- Copying files would be nice but is a plus.
