Apple Watch Series 4 Battery Information

Apple Watch is so capable you’ll want to wear it all day long. So we made sure we gave it a battery that lasts all day too. Our goal for battery life is 18 hours after an overnight charge, factoring in things like checking the time, receiving notifications, using apps and doing a 60-minute workout. And because everyone will use Apple Watch differently, we tested several other metrics as well.

Apple Watch All-Day Battery Life testing was conducted by Apple in August 2018 using preproduction Apple Watch Series 4 (GPS) and Apple Watch Series 4 (GPS + Cellular), each paired with an iPhone. All devices were tested with prerelease software. Battery life varies by use, mobile coverage, configuration and many other factors; actual results will vary.
