The Apple Watch Ultra 2 Has the Best Battery Life

Because of its bigger size, the Apple Watch Ultra has the biggest battery we’ve ever seen on an Apple Watch, which is something you’ll love when you’re out on weekend wilderness excursions or you simply hate having to charge your Watch every night.
According to Apple, the Apple Watch Ultra 2 lasts up to 36 hours with normal use and up to 72 hours in Low Power Mode.
While these numbers might change depending on the user, most casual users will be able to carry their Apple Watch Ultra for a couple of days without worrying about battery life.
