Do you own an Apple watch? I own the series 1, the Gear S2/S3, Moto 360, and the Huawei watch.
The Apple watch gets me through 12 hours of use and only loses around 20% battery. Granted it doesn't have an always on display though.
My S3 can come pretty close to this and it does have LTE. Android watches have pitiful battery life in comparison.
So please tell us, how is battery life challenging in the current Apple watch form? Hint: it isn't.
And how would new low power chips for the new Apple watch not keep us on par with current battery use?
I think you are talking out of your arse here, while I am deriving my input from real world use of Tizen, watch os and Android wear 2.0
That's how it behaves for you and your use case, it doesn't behave that way for mine. I can only imagine if I bought an LTE version and I'm constantly running into cellular coverage issues if I'm in the car, walking about time, or just sitting at home. Radio waves have to get through woods, walls, other EMR and that will drain a battery quickly.
