The battery in the Apple Watch, like just about every other Android Wear SmartWatch, only lasts a day, which is not promising at all. Apple says users can expect to eke out approximately a day of battery life based on "normal" use, where power users who expect to pull down tons of notifications and other bite-sized data will need to charge the watch in the middle of a day! Apple has outlined specific information about Apple Watch battery life on its website, claiming that the wrist-worn device gets ALL-DAY battery life of 18 hours on a single charge based on mixed usage, and up to 72 hours in Power Reserve mode.
Yes you heard it right. In Apple's word All-Day means 18 hours! Not 24! Actually that "all day" claim technically syncs up with a normal sleep schedule and it takes only two and half hours to fully recharge. But Apple's methodology behind these numbers and how they compare to the best SmartWatches deserves a deeper dive.
The Way Apple Calculates It's Watch Battery Life-
Apple claims that its iPhone-compatible SmartWatch achieved all-day battery life of 18 hours during tests based on a pre-production Apple Watch and pre-production iOS software. Its 18 hours of "mixed use" consisted of 90 time checks, 90 notifications, 45 minutes of app use and a 30-minute workout with music playback via Bluetooth.
Check the time or light up the screen fewer times, and Apple Watch's battery could beat these estimates. Get a deluge of notifications, and it may die on your commute home from work.
Apple Watch battery Life Under Specific Tasks-
More specified tests by Apple yielded different results. A "watch test" netted 48 hours from five time checks every hour, with Apple noting that each screen-lighting timecheck lasted four seconds.
The most power-draining battery test was a "talk time test" using the Apple Watch phone app. It lasted three hours in this Dick Tracy-esque mode that still required a connected iPhone. Apple's "workout test" and "audio playback test" each resulted in 6.5 hours of battery life. The company said the heart rate sensor was on during the workout session.
