My Sony Smartwatch 2 will go for 4 days before needing charging. BUT, that is with hardly any apps streaming data to it. I have 3 pages of apps loaded and set the alerts to vibrate when new messages, text, e-mail, etc is received and then I need to charge it daily. So, the length of charge lasts depending on how much you use the watch.
When I first got the watch it ran nearly every app flawlessly. Then, the main link application got an update and now several of the apps don't work.
What I really like about the watch concept is being able to receive my communication when it happens and not need to pull my phone out to see who is calling or read the text. If I use my BT ear piece, I can answer or reject calls by seeing who is calling on my wrist. I can answer by touching a button on the watch. Or, reject the call altogether. That's nice. If I'm having a busy day and need to keep my eye on one of my stocks for critical movement, I can turn on my stock tracker and I get streaming stock quotes updated every minute. I also have a nice weather radar screen to track storm activity. Of course I also have an internet browser but that one is difficult to use on a one inch screen. Twitter and Facebook apps work well as does a news ticker too.
In other words, anyone who believes these smart watches are just about sports really hasn't kept up with what they can do these days.
My old Thunderbolt is about worn out and after 3 years is in dire need of replacement. There are dead spots on the screen making typing nearly impossible. I have to use the Google voice command most of the time. The power button also has lost its spring action and sometimes sticks pushed in. I have decided to wait for the iphone6 and the iwatch to see if that is going to be right for me. After almost a year of my wife having the iphone5 I see the battery life is adequate and I no longer fear being without a spare battery. we have little charger cords for her phone in both cars and one in each suitcase and each of her purses so she never has to worry about not having a charging cord handy.
Hey Scott- did you get rid of your Brietling? Bet it's worth more than Eva paid now. On my last cruise, I saw my T Touch Tissot Titanium I paid $600 when they first came out was selling for $1400. I was shocked at how much it went up. I'm thinking it had to do with the money exchange rate.
