I understand where you're coming from, but I don't know that it's a common problem. I've had my Pebble for about 4.5 months now and remembering to charge it can be interesting. I usually forget when I last charged it, but even then there are low battery alerts. I know that it'll last about a day once I see the "20% remaining" message, so I just charge it within 6-12 hours of that message.

It's not really too much of a hassle to remove the watch for a couple hours while sitting at my desk, and I've heard of people who charge it while sitting at a desk wearing it.
