I find the battery life on my Pebble to be much longer than the author is finding: it was still going 8 days after I misplaced it in my car. When actively being used, I find it lasts 3-4 days. It's still short enough that it's easiest to get in the habit of charging it overnight, but it easily survives one or two forgotten charges.

I believe that if you use a watchface that updates by the second, rather than by the minute, it cuts battery life down quite a bit. Perhaps that explains the discrepancy.

You have to disable the motion backlight, it turns on far to easily. With it on I got about 2 days of battery life. With it off I get 5-7 days.

Thanks for this, I'd been wondering why mine was turning on all the time and I'd forgotten about that setting. Settings->Display->Motion

I would think it would be a lot more useful if you could charge it from your phone itself. Pebble's battery is 130 mAh[1], so (unless I'm mistaken) you could charge it using 9% of an iPhone 5s' 1560 mAh battery[2]. If the charger had USB passthrough you could charge both at once.

Of course, then you'd be carrying an extra cable, but that might fit with those in Pebble's target demographic (in a bag along with your tablet/laptop and such)

Ditto, and I have the motion backlight on - I get 5-7 days easily out of mine. More to the point, the battery life is long enough that I can simply use it until the battery indicator shows up, then just charge it that night.

Agree, I've been recharging in infrequently enough that I can't tell you exactly how long I get, but somewhere on the order of 5-6 days I think. I turn it off at night though to save a little extra (I don't need notifications while I'm sleeping).
