I believe it is true, if the member I was responding to wants an easy 24+ hrs of use from his series 6 before charging. And as we both know, that also depends on type of use, complications, and watch face.thats not really true. Apple claimed 18 hours for series 4, 5 AND 6. sure the 5 & 6 use more power for some of the new features but they use LESS power for some things like the new CPU which helps balance things out. I’m finding battery life on my S6 to be comparable to slightly better than my S4 with all features turned on. I’ve heard the S5 had a more difficult time with battery life for the first few months until software updates improved things but I didn’t have the S5.
I think some people are making a bigger issue of battery than it really is, considering all that the watch does.
