I just got my Transformer a few weeks ago and the dock a few days ago. The constant battery drain from the dock is bothering me. I keep them attached, have set the wifi policy to "disconnect when screen is off" and I still find the dock battery draining at an alarming rate. I stuck Juice Defender on there to ensure the damn wifi was off when the screen is off (basically a second app which does the same thing) but the result is the same drain. Last night I manually turned off wifi with all the above stuff and it's still draining. The draining I'm describing is 50% dock drain while the tablet is docked, powered on but in standby (dock closed) over 12 hours. My DroidX does better and it has a smaller battery and a cellular radio. Something isn't right with the Transformer / dock. Random observations: The wifi policy "off when screen off" doesn't seem to stick. I've set it twice in the last 2 days. It jumps back to "always on". I haven't found the pattern as to what circumstances cause that to happen yet. You need the Asus wall plug to charge this thing. Plugging into the wall plug (via USB) I use to charge my DroidX results in the Transformer not charging. That's inconvenient. Add another wall plug to my arsenal. Plugging the Transformer into a PC does not charge it. My computer complained about not having the right driver so maybe that's a factor. Why the heck does wifi use the most battery? The screen is huge and should gobble power, yet it's always wifi which is highest in the Settings. This is all with the firmware update of the other day. Also the "wake from keyboard" is off. Cool tablet, but I'm not digging the constant need to charge.
