🐩 Does Apple Watch Series 4 Have Always On Display

Depends on how much you have on your home screen. Using solid color backgrounds will have a more noticeable effect on battery life than if you use a more black background. From some reviews of S7 they say AOD can drain approx extra 20-30% battery. From My S6 experience it does not make any appreciable difference. .
