General 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 was 18 hours after an overnight charge, factoring in things like checking the time, receiving notifications, using apps and doing a 30‐minute workout. And because everyone will use Apple Watch differently, we tested several other metrics as well.

Apple Watch battery testing was conducted by Apple in August 2016 using pre-production Apple Watch Series 1, Apple Watch Series 2 and Apple Watch Edition, each paired with an iPhone; all devices were tested with pre-release software. Battery life varies by use, configuration and many other factors; actual results will vary.

All-Day Battery Life

Up to 18 hours

Testing conducted by Apple in August 2016 using pre-production Apple Watch Series 1, Apple Watch Series 2 and Apple Watch Edition, each paired with an iPhone; all devices tested with pre-release software. All-day battery life is based on 18 hours with the following use: 90 time checks, 90 notifications, 45 minutes of app use, and a 30-minute workout with music playback from Apple Watch via Bluetooth, over the course of 18 hours. Battery life varies by use, configuration and many other factors; actual results will vary.

Talk Time

Up to 3 hours

Testing conducted by Apple in August 2016 using pre-production Apple Watch Series 1, Apple Watch Series 2 and Apple Watch Edition, each paired with an iPhone; all devices tested with pre-release software. Tested with call placed from Apple Watch. Battery life varies by use, configuration and many other factors; actual results will vary.

Audio Playback

Up to 6.5 hours

Testing conducted by Apple in August 2016 using pre-production Apple Watch Series 1, Apple Watch Series 2 and Apple Watch Edition, each paired with an iPhone; all devices tested with pre-release software. Tested with music playback from Apple Watch via Bluetooth. Battery life varies by use, configuration and many other factors; actual results will vary.

Workout

Up to 8 hours

Testing conducted by Apple in August 2016 using pre-production Apple Watch Series 1, Apple Watch Series 2 and Apple Watch Edition, each paired with an iPhone; all devices tested with pre-release software. Tested with workout session active, heart rate sensor on, with iPhone. Using the built-in GPS of the Apple Watch Series 2 without iPhone, workout time is up to 5 hours. Battery life varies by use, configuration and many other factors; actual results will vary.

Charge Time

About 1.5 hours to 80%

About 2 hours to 100%

Testing conducted by Apple in August 2016 using pre-production Apple Watch Series 1, Apple Watch Series 2 and Apple Watch Edition, each paired with an iPhone; all devices tested with pre-release software. Charge times are from 0‐80% and 0‐100% using the included Apple Watch Magnetic Charging Cable. Charge time varies with environmental factors; actual results will vary.

CPU Performance

Up to 1.5x faster than previous generation Apple Watch

Testing conducted by Apple in August 2016 using pre-production Apple Watch Series 2 and shipping Apple Watch units with pre-release software, paired with pre-production iPhone 7 and iPhone 7 Plus units and software. Results based on the performance of common user tasks and reflect the approximate performance of Apple Watch.

GPU Performance

Up to 2x faster than previous generation Apple Watch

Testing conducted by Apple in August 2016 using pre-production Apple Watch Series 2 and shipping Apple Watch units with pre-release software, paired with pre-production iPhone 7 and iPhone 7 Plus units and software. Results based on GFLOPS performance and reflect the approximate performance of the GPU.
