Yeah, and if you read closely, they also specify that they are basically using the watch heavily in these 18 hours with workout tracking, music playback, telephone calls and whatnot. Which is not my daily use case and so I expect my battery lasting much longer (which it does) - and which should be no surprise here, right?
Look, I honestly don't care much about how YOU use the watch and if you charge that it every night or not. But I hate charging my watch all the time and if I it means not using some features, then be it. My XS Max lasts 3-4 days, I just would love to get 3 days out of my watch, too. I had the Huawei Watch GT which lasted 10-12 days.....
So that's why it's got an option to disable it, right? My watch is hidden under my sleeves anyway, so I'm totally fine with raising my wrist to see the display. I would get the S5 if disabling the AOD would give a better battery life, but if it doesn't, I'll stick to my S3 and S4 for a little longer. Just hoping the damn S6 will have amazing battery life :/
