This time around it took almost 5 days for my Pebble Time to get down to a 20% charge. I thought that wasn’t bad at all.
The most interesting thing was that not only did I get the nice alert to the fact that my battery was low, but also the watch face itself went red to constantly remind me.
I don’t know if all watch faces either do this, or are capable of doing this, but I think it’s a really useful feature.
