Battery life for movies on flights?

[mgftp]

Taking my Nexus on a few long flights this week. What can I expect for battery life with airplane mode on watching movies?

About half a movie would be my guess.

depends... for 720p MKV movies, I'd say about 2 hours max. regular 480p shoudl run another half hour longer.

(all assuming brightness at 20% or lower)
