I got the M6 (original body) with the kit 18-55 lens. Everything is stock on this body and I've updated her to the latest firmware.
I had used the camera around the house to shoot and test and everything seemed fine.
However, I took her out on our first big trip overseas to Greece these past two weeks and the first thing I noticed is how quickly she seemed to go through batteries.
I used her like I did my dSLRs - always on, with the LCD and camera shutting off after 1 minute. LCD brightness up pretty high, with ECO Mode and Bluetooth turned off.
Image stabilizing was on in the lens as well, I believe.
I didn't use the flash much and I didn't do too many long reviews, other than the automatic 2 sec. review after each shot.
On my dSLRs, I can go usually anywhere from 350-500 shots before having to think about the battery.
On my M6, I can get at most 125-150 shots/battery, even though the instruction manual gives this battery pack a rated life of around 295 shots.
These are a mix of original new Canon LP-E17s and Wasabi brand LP-E17s.
