Samsung Galaxy Watch 42mm vs 46mm: Which is Better?
Both watches looks stunning and classy, while the 46mm with a larger display allow you see more at a glance than on the 42mm, it’s quite bulky. In other words, the 42mm is a more compact watch and the better choice for women and people with smaller wrists, while the 46mm is a more befitting wear for men and those with fatter wrist.
Battery capacity differs slightly, but it doesn’t necessarily mean much difference in battery life when you consider that the 46mm with a bigger battery capacity will need those extra to power its larger 1.3 inch display. However, from actual use, the 46mm has a longer battery life than the 42mm. You can get up to 4 days with the 46mm compared to about 2 days+ of the 42mm.
