No offence, I'm sure you love this device, but to me this sounds like a wafer-thin marginal improvement that does not seem worth the effort required to keep yet ANOTHER device charged. Seriously, we're talking 2 seconds saved per look? If the argument is "it adds up", you're looking at you smart device (phone or watch) too much! With the watch you then you have to decide whether or not to take your phone and fiddle with it. IMHO everything on this list works as I want with a phone, except checking the time, so I have a Swatch from 2004 for that (which has a replaceable batteries that lasts years each).
Smart watches as they currently exist fulfill a manufactured desire (again, IMHO!)
Of course, the ideal would be turn off the phone entirely, but I thought the Pebble was an elegant & respectful way to remain on-call with work, but also remain present with others. I can see how it would be useful to some people.
As for battery life, my pebble time steel lasts about a week between complaining about needing charging, which is at about the 35% range, where it could survive probably several days of use if you forgot to charge it. And if you have a smartphone it's probably not a significant inconvenience to add another cable to your charger one day a week overnight.
what
This one is actually the killer app for me. I use it while on my bicycle where pulling out my phone and unlocking it to monitor my progress is quite unwieldy. I used to use a bluetooth headset for this, but not having anything covering my ears is both safer and more convenient.
* In the kitchen to time cooking, to save getting half cooked food on my phone.
* To have a quick glance at incoming notifications while walking.
* To send quick replies to some of those notifications. * To check the time (its not only a smart watch, but also just a watch).
* To track how much sleep I'm getting, and the quality of that sleep.
* To track my exercise, both while running with real time information from my phone, and passively tracking how much walking I do.
* To control music I'm listening to in the shower.
* To give me at a glance directions when Google Maps is navigating for me, rather than walking around staring at my phone.
