So thats why the 6d has pathetic battery life compared to any rebel or the 60d. great
No, it's not a bug, but a feature that can be turned off.If gps would force turn off on camera off each fix would take another minute... so in essence this saves battery life because you don't have to leave your camera on to have instant gps.
Btw the larger battery drain 6d vs 60d (I have both) is because the ff sensor draws much more power. If that's a problem, buy a mobile phone with an even smaller sensor and use it for even longer than a 60d.
I guess it would probably interfere with the Magic Lantern software that some of us have as well.
It's not compatible unless adjusts the memory addresses of the Canon firmware functions, that'll take a dev ~1 hour - but it's probably not worth it right now as there's no real need to upgrade and you can downgrade to 1.1.3 anytime.
