Apple Watch will get 'all-day' battery life of 18 hours, Battery Is Replaceable

Apple Watch can do a lot of things like lets you pay for stuff with it, open your garage door, answer calls, check through the security at the airport, but how long can it do them for?

Tim Cook at Apple's event revealed that the Apple Watch's normal expected "all-day" battery life is about 18 hours on a charge factoring in activities like checking time, receiving notifications, using apps and doing a 30-minute workout. Apple says the "battery life varies by use, configuration, and many other factors; actual results will vary."

Apple's listed its results and testing methods of the Apple Watch's battery:

All-Day Battery Life - 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; 

Watch Test (up to 48 hours) - testing conducted by Apple in March 2015 using preproduction Apple Watch and software paired with an iPhone using preproduction software with 5 time checks (4 seconds each) per hour;

 

Talk Time Test (up to 3 hours) - testing conducted by Apple in March 2015 using preproduction Apple Watch and software paired with an iPhone using preproduction software with a call placed from Apple Watch. 

 

Audio Playback Test (up to 6.5 hours) - paired with an iPhone using preproduction software with music playback from Apple Watch via Bluetooth. 

 

Workout Test (up to 7 hours) - paired with an iPhone using preproduction software with a workout session active and the heart rate sensor on. 

 

Power Reserve (up to 72 hours) - if your battery gets too low, Apple Watch automatically switches into Power Reserve mode so you can continue to see the time for up to 72 hours. Testing conducted by Apple in March 2015 using preproduction Apple Watch and software with 4 time checks (4 seconds each) per hour. 

 

Charge Time (~1.5 hours to 80%, ~2.5 hours to 100%) - Charge times are from 0% to 80% and from 0% to 100% using the included MagSafe inductive charger.

 

Apple states that "Apple Watch battery performance claims are based on test results from the 38mm Apple Watch. A 42mm Apple Watch typically experiences longer battery life"


Apple Watch can be charged using the MagSafe charging cable. It's a round disc that fits on the back of the watch and then plugs into a standard USB port. The connector's magnet gently snaps itself onto the back of the watch and begins charging.

There is also Griffin WatchStand which is a charging dock for the watch. It houses the MagSafe charging cable in an angled cradle to keep the Watch for charging.

In addition, An Apple spokesman confirmed to Techcrunch that the Apple Watch battery is replaceable. There are no details on how much the replaceable battery will cost.

Apart from the battery being able to be swapped, its unclear whether other components inside the Apple Watch can changed like upgrading CPU or RAM when new hardware is released as people would not be willing to spend their hard-earned money for a $10,000 watch because the existing hardware on the Apple Watch will become outdated after a couple of years.

The Apple Watch goes up for pre-order on April 10th, and launches on April 24th.
