Qualcomm Announced A New Watch SoC 4100 (CPU)

C.sco, he said for those who plan to keep for 3+years. Imho you should not need to worry for 5years except for a faulty unit which may trouble you even bevor 3 years. I sold my Fenix 3 to a Friend who still uses it daily. After 7 years no dent in battery life.

I think we all want to convey the same thing, I just wanted to clarify that this is way longer than 3 years if you consider cycle times

Somebody is needed to disassemble his Garmin Venu 2 which has hardware from a next version of Garmin watches with newer CIQ compatibility. :) 

It was mention in a review of the Venu 2 that it now had a GPU within the CPU.. So something like the RT500 is possible..
BUT I do not know If it makes much sens to put it in the Fenix line unless you get Amoled /lcd display

@AJR: its more than just the chip itself (though I will say the qualcomm ones are lagging compared to Apple Watch and Tizen chips), its the screen, and that extra connectivity and the fact that wear os isn't designed to take advantage of the low power core (in the 3100 and the 4100+) as they also allow the use of non low power core chips (2100 & 4100).

Take a look at the Venu2 which has a good screen similar to what wear os/tizen and apple watch use - its also with a AOD on is limited to approx 2 days battery life, just like the others. The difference comes when the AOD is off, they tend to get 3-5 days max compared to the Venu2's +5 days - and that is due to not using low power cores properly.

They also have more than 500 MBs of RAM chips to run their operating systems and other apps. Their coding is heavy, too unlike Garmin which is simply built to do the job.

Wear and Tizen ideally need at least 1GB of ram to run fluid. 0.5GB gets the job done, but there will be occasional stutters and lags.
