Clever Hack Gives Your DSLR Nine Times the Battery Life
I think it will work with Q and GR too

I just turn off the display and go shooting all day long. Easily getting up to 2,000 shots on my K-5ii per charge.

can you shoot video so long?

I'd hardly call that a 'hack', it's just plugging in an external battery.

Yes!
On the K-01, a single battery is good for Four Hours of video shooting in my personal experience.
I only need my second battery occasionally.

For video I've found a Canon battery & camera combo is good for about 45minutes on the 550D, 7D and 5D, but the Li90 is good for hours of recording.

I'm pretty sure it has more to do with being able to use manual lenses, or at least not having the Iris drawing power all the time like the EF mount does.

I don't know as I don't shoot video.

On the focus bit, you should know I do back button focusing as well with plenty of manual in between. So there could be power savings there as well.

I dig the idea, though I'd mount the larger battery to the tripod. However, with my K-7 one battery could go about three hours for video. With my K-3, I recorded one day for 16 hours and only used two batteries -- including the one that came with my K-7 however many years ago.

Where that works well is if someone wants to Jerry-rig an HD camera for long-duration interval videos or as a security cam or the like.

Yeah, not really a hack, nor does it "increase your "battery life"" (ie: makes your existing stock battery last longer). All it really is is a way of getting more shooting time without having to change batteries... by connecting a larger battery in the first place. Imagine what you could do with a 12 volt car battery stepped down to supply the correct voltage. You could shoot for years!
