And in nomal watch, how long to charge fully battery 100%

Thanks in advance

As for lasting for 1 day of use, I found that turn the brightness to about 2 levels works for me during normal use unless I am outdoor in bright sunlight. You could also try to turn off always-on screen can help as well as disable tilt-to wake. I kept them both on and get 1 day of use but if you need a bit more juice, maybe try to turn them off. I also found that sometimes depending on the watch face you use can have major impact on the battery life as well.
