    Would it save battery life to put your watch in Grayscale mode (under accessibility)? I sort of like it - I get tired of seeing too many popping colors.

    It would probably have no material impact. Though, if anything, it would consume more power, because the colors are created through constructive interference, meaning that more LEDs must shine to create white colors versus single-hue colors.

    Use the Simple face 'striped' down/no Complications and in pure green or red (blue is a larger sub-pixel) to save the most power. The more black the less power. As exxxviii points out pure white is the most power hungry since all 3 sub pixels must be driven. Monochrome will use the most power and red or green using the least. Also bigness needs to be a minimum you can tolerate.

    Me, I would just rather charge it and use it. :eek:

    I went with this screen attached as my power saving face. They have a light green one which looks nicer, but since it's not a pure green, I assume it takes more power. I'm also experimenting with having the heart sensor off because it seems like it's a power sucker and I have little use for it. Not sure though, It's kind of entertaining to check my heart beat every now and then (I'm more interested in distance and time than calories). One other thing I've stopped using is the breathe app because the heart sensor stays on the whole 5 minutes I run the app! Seems like that would kill the battery in no time for someone like me who uses the app like 5x/day. I just use the timer app instead, which is not as great, but does the job.

    I'm Just seeing how long I can get the battery to last without sacrificing useful things. Not for full time, but in case I need to be frugal during traveling in the future.

    I wonder if airplane mode disables the heart sensor as well..
