David Pierce at The Verge:
This watch just happens to do more than tell time.
Until, that is, it doesn’t do anything at all. That happens about 12 hours after I take the watch off its charger, a cool black wireless dock that the 360 slots into sideways. Motorola says the 360’s battery lasts a day, but I haven’t seen it last that long yet. I don’t expect a smartwatch to last weeks or years, but it ought to be able to last a day and a night no matter how much I use it. My watch now dies before my phone does, and that’s unacceptable. I’ve already spent too much time wearing a dead Moto 360, and good-looking a bracelet as it is, that’s not what I’m spending $249 for.
If Apple has something up its sleeve for next week, I hope this issue has been addressed.
