OP and co-founder here. Anenth and Sandeep hacked this up at Droidcon Bangalore Hacknight last weekend, and we polished it a bit since then. We have lots of tweaks/improvements planned for it, including:
* Auto-posting (via server) to FB/Twitter when you battery drops to 20%
* Show call-receiver's battery % when you call them
* Crowdsourced battery life data<p>Would love feedback & ideas here or droidjuice@ideophone.in
