I'm getting amazing battery life BT tethered with Null 20 as long as I leave the wrist motion turn-on disabled (with that on mine also dies in 5 hours)
I had mine tethered for 12 hours today (I don't need to, but I was just trying it out syncing gmail etc.), and still had 86% left on the battery readout.
