Haswell RMBp 15 video playback time on battery

[Gauranga-caran]

Hi, folks.
I was trying very hard to squeeze good battery life out of my
late 3013 i7 2.3/16/512 ssd 750m model

In the reviews they say it lasted for 8+ hours video playback, although
I can't make it live more than 7
1.5 hours is a huge difference

I have tried all available video players, as I watch fullhd mkv files.

the latest movist is taking less processor time during playback, so I use it, since vlc,mplayerx, and others use at least twice processor time.


Also setting resolution to 2880 helps a little, brightness 40%, but still, about 7 hours.

Any suggestions ?
The battery is now 29 cycles, 100% capacity, so thats not a problem

Depends on what you use for video playback. If Apple quotes 8 hours, I assume they mean via videos on iTunes.

As I`ve stated in my previous post, I use movist.

quicktime is pretty useless, since it doesn't support external codecs in 10.9.

Any real life experiences ?

I bet your poorer result is due to the need to recode the stream on the fly. Apple's results were achieved with iTunes content (AVC+AAC) that plays natively in QT. Even if the video stream in your MKV is with 99% probability AVC, the audio (DTS or AC3) needs to be transcoded.
PS Mac BluRay Player plays MKVs with DTS audio flawlessly.
PPS I also still use QT 7 on my 10.9 because it can take advantage of Perian.
