Jumping in to say that I might never buy Li-ion batteries for my Xbone, and kind of regret the money I have been spending on Xbox 360 batteries over the years. Enloops last almost as long if not longer. Can go through much more cycles. They will also last years when not in use and not the 2-3 months that the Li-ion packs do.
I even picked up some of their XX series. They don't last as long on the shelf (1 year to retain 80% instead of 5 years (this is only for a single charge and can be recharged to full for the most part from there)) and don't support as many cycles (500 charges before it can only be charged to 50% vs 1800). But the extra 1000mWh can be worth it (2x 2500 vs 2x2000) in-terms of play sessions and a dollar per battery means I can still buy 3-4 pairs for the cost of 1 360/one battery and get 2000 cycles and 14000 game play hours out of them. I can tell you that 3-4 360 batteries that I have had basically die on my since 2005 have not seen anywhere near that kind of service. I probably averaged less than 1k hours per battery. I could get more play out of the base eneloops and spend less, but to minimize battery swapping is more useful for me.
Not to pick fights but it does make it that much harder to the use the DS4. None exchangeable Li-ion battery that will only last ~4 hours for me. Where the Xbone has a swappable battery where you can make the choice of which battery and of which composition. Li-ion MS pack, LI single use AA, Alkaline AA, Alkaline rechargeable, Ni-Mh rechargeable, LSD vs. RSD. Different choices in manufacturers, in capacity, in recharge cycles.
