Battery life rMBP vs MBA 13

[Myrdin76]

I'm deciding between a rMPB 13 and a MBA. I'm almost convinced to buy the rMPB because I prefer the screen. Most of the time I won't need the better batterylife of the air except when I have to study in a library without a poweroutlet. Let's say I sit there from 10:00 to 20:00, with regular breaks. The brightness on 30/40% and running Safari (+- 20 tabs), Word and Spotify. Will the rMPB's battery last?

I would suggest that you buy the rMBP and try it out to validate it meets your needs.

You'll get much better battery life with the MBA but you have to decide between power efficiency or a more powerful computer with a better screen.

I'm just wondering if the rMPB will last through the 10 hours of use

I'm able to get ~10 hours (maybe more) with the screen brightness at 50% or less running Safari, Pages & iPhoto all day. I don't know what adding a music streaming service would do, but I suspect the constant WiFi usage wouldn't be good. You don't have some other device or method for listening to music?

Doubt it very much.

This is on a 15"
Realistically I'll probably only get ~9 hours
