So yesterday I picked up AW Series 1. I owned a stainless steel series 0 38mm at launch, and have been using a work-provided series 0 42mm sport for a few months.

My observation, even after one day, is that Series 1 has a better battery life than series 0. Im chalking this up to the S1P processor, since my S0 42mm watch will be in the 30% area after 18 hours of purely notification use, while this S1 watch, also in 42 is currently on 51% after 15 hours of quite prominent use. The S1P's speed actually makes it more efficient to use my watch for apps now, rather than pull out my phone, which simply wasn't the case with series 0, meaning it was literally a notification filter.

Is anyone else noticing better battery with their S1 watch?

I do miss the stainless steel, so I'm not 100% on keeping the S1 yet, although it'll cost double to trade up to the steel S2, which is a tough pill to swallow, given I've no use for swim-ability, gps or catching more nits outdoors.

I'm confused by your above statement. See bolded print above.

I have series 1 and didn't buy the first generation Watch so I can't compare the two, but I guess the new CPU is more power efficient than the old one.
I haven't read any detailed comparison yet, but if you look at iPhone every year they ship a new Ax SoC faster and more power efficient so I assume the same happened with Apple Watch.
