My comment from Smartwatch Ticks: So, yes, you can get several days on a charge, but you are going to have to turn everything off except the basic watch setting. I had it all on - the health metrics, gestures, Bluetooth phone, etc. I got about 15 hours to completely dead. An it takes 2-1/2 hours to charge. There are other issues. The firmware is buggy. Sometimes pressing the main button gets you your apps, and sometimes it doesn't. The always on display just quit working. I had it set for 3 minutes initially and then changed that so now it doesn't work at all. And as for the watch faces, you can change just one. It will gladly let you download several, but you are just changing the same one over and over, and you can't even choose which butt-ugly one to replace. And the temp display on most of them is wrong. Plus, the compass is useless, as it must be recalibrated daily. Just so much. Bottom line is that the watch bands alone may be worth the price, but the watch itself isn't worth the trouble of putting it on, in my humble opinion.
