Evening everyone,

Due to an unfortunate circumstance I’ve had recently with a Dell laptop of mine I am currently in the market for a new machine. As my working environment is quite mobile, having good battery life is a must for me. I noticed that the current MacBook Air has a smaller battery by about .4wH compared to the previous model (49.9wH vs 54wH), which is certainly perplexing.

Normally I would have gone with the baseline Air and called it a day, but that’s when Apple up and released an updated version of the MacBook Pro. The Pro has a significantly larger battery at 58wH compared to the Air, but it also has a more powerful processor to boot. Assuming that the load between the two would be similar (writing documents / emails, web surfing, entertainment consumption), would the battery life on the Pro be slightly better due to its higher capacity?

Thanks so much for all of your insight!

The Air has lower power consumption so the smaller battery can yield longer life. Apple publishes expected battery use for each model. While YMMV from the published figures they are valid for comparison.
