I don't see 2600 mAh as a small battery size. That's still pretty huge, it's just smallER than what they did last year. But the screen is smaller and likely more efficient and it's running better software - so this would be where I lean back on talking about battery life, rather than battery capacity. Obviously more capacity would be better, but there's a cost to doing that just like everything else. Something has to be given to get whatever.
