Its true my I/O version went 8.4 hours with 80% time with screen on and had 55% battery left.
Wow! I'm definitely thinking about returning the Iconia I just purchased for this one.
The Iconia is nice & has a lot of features, but it's quite heavy & battery life is on par with my Android phone.
I would like to have more battery life since I will be browsing the web more on my tablet than I will on my phone.
