Battery Life
Like other recent Canon camera releases, the 6D2 utilizes the LP-E6N battery, though it is "backwards-compatible" with the older LP-E6 batteries used by many of Canon's last generation DSLRs. You might get marginally better focus speed or battery life with the newer batteries, but in many situations you won't notice the difference. What's interesting is that the 6D2 has many of the same "pieces" as the 5D Mark IV (GPS, touchscreen, processor, etc...), but the 5D Mark IV flies through batteries by comparison. The rating differs by 300 shots (900 for the 5D Mark IV, 1200 for the 6DII). Real world shooting seems even greater, however, with the battery life indicator scarcely budging on the 6DII. After several weeks of review, I've not yet had to recharge the battery, which simply wasn't the case with the 5D Mark IV. Battery life is a definite plus with the 6D Mark II. In real world use it seems to me that the battery life is near twice that of the 5D Mark IV, which can be guilty of underperforming its specifications while the 6D2 seems to outperform them. This is definitely a solid plus for the 6D2.
