battery with video

[Gaura Mohana]

Hi there
I'm wondering what battery time i can expect if i watch .mkv files (NOT HD - each 20 minute file is somewhere around 50mb) with brightness 50%, and key backlight off, and no other programs running, in MplayerX?
Can i expect 5 hours? shooting for too much?
thanks

Yup i was getting 5 hours for exactly the same kind of usage you are putting it to.
Albeit:at brightness at just 1 above total darkness.

100% brightness, 1080p mkv, 4 hours.

You can probably get 5 hours with lower brightness and lower quality video format.
