I decided that, cool as the shake-to-light feature is on the Pebble watch, I turned it off. Saves battery life. And, frankly, it can be annoying if one sleeps with a watch or is in a movie theater.
But I don’t know how long my year-plus-old watch lasts in this setting because I have taken to setting it to charge when I get up in the morning, before I take a shower. I put it back on when I get dressed. Yes, I know the watch can go in the shower, but it still gets in the way of, say , washing my wrist.
