I've had no issues with the a35 battery life in all honesty, but then I'm only driving a pair of ciems or a pair of sennheiser hd 25-II's. Tried the fiio x5-III recently and was shocked at just how quick (and warm!)the battery drained (thanks in no small part to android). Although I charge it every night I suspect I could go two three days without charging.
I don't have any issues with battery life on the Sony DAP's either but if Sony wants to throw in a larger battery to increase it further that is still an nice little bonus. Anything that increases the value of the A45 is a bonus to me.
