I'm looking to purchase the new Surface Pro. I've been debating between the i5 and the i7 models. Assuming a user performs the same tasks on both models, would the battery life be the same or would the i7 drain the battery faster as it is more powerful? Would bigger SSD sizes also drain batter faster? Again, I assume the user is performing the same tasks on both models.
I have the exact same question. I posted a couple of questions in the comments for Matt and Daniel based on this article. Still have no response. Pending.

For battery saving tips, I found this video by Linus insightful.

Current online stories and forum posts on the intel I chipsets seem to suggest that for general purpose use the core i5 is the best bang for your buck in terms of balance cost and performance. i7 seems to be overkill. But if you need it you need it.
I've already read many stories and posts on the silent fan. I think in the beginning many fans will be ideally "silent" when new and fresh. It is my experience though that over time the fans become noisier. Not sure why but mechanical parts fatigue and dust over time due come to mind, no matter how tiny the vent slots are.
I agree with others that fans will consume some power. I don't know how much. But the fanless i5 design does make me curious and does provide food for thought about the impact of mechanical ventilation on battery perfomance on windows mobile tablet-pc devices. After all, why would they consider bringing this design to market?\
For me choosing between the M3, i5 or i7, I think the i5 is the most interesting propsitiion for general all-round use.
I agree that batterylife will likely not be very different between the three models. But I do think best batterylife will likely be M3-i5-i7 in terms of best battery life in one form or another.
From one or two early reviews I read that the i7 was getting a realistic noraml use all day batterylife 11-12 hours. So it's likely the i5 and M3 could potentially hit that 13,5 hour mark. Possibly more with Linus' tips.
