True to the rumors, Apple Watch comes with a special Power Reserve mode that will lightly sip on juice so your watch can keep ticking.

Tim Cook didn’t specify how long Apple Watch’s ‘all day’ battery lasts, but Apple’s website specifies you could potentially keep your watch alive for an extra 72 hours in Power Reserve mode.

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. Battery life varies by use, configuration, and many other factors; actual results will vary.”

You should be able to get 18 hours of battery from your Apple Watch. According to Apple’s tests, that includes 90 time checks, 90 notifications, 45 minutes of app use, a 30-minute work with music playback from Apple Watch via Bluetooth.

Talk Time clocks in around 3 hours with the battery, while audio playback lasts for 6.5 hours. If you just want to use it during workouts it should last for 7 hours straight.

Charging your Apple Watch from zero – 100% will take 2.5 hours based on Apple’s tests, or 1.5 hours to reach 80%.

Interestingly, Apple says that a “42mm Apple Watch typically experiences longer battery life.”

    Does any one know, probably not yet since no one has one, how this will work with Nike Plus? Since it does not have GPS, Will you need to run with this tethered blue tooth to your phone for GPS? and if so, won’t that kill the phone battery on long runs? My wife runs half marathons, and she is not the fastest kid on the block so it takes her a long time to run the distance she is doing in her training, and her phone can barely make it. I was hoping to get this to be a smaller item and run her Nike plus and can listen to music, but without GPS Nike won’t work, so that kind of puts us back to square 1 and makes this watch somewhat useless for what we want it for. Thoughts…

    I don’t get it. Apple is doing all this stuff to compensate for their bad batteries…why don’t they just give us good batteries? I had a 3rd gen ipod Nano that had an AMAZING battery. three days, 5-8 hours a day, no charging. Every other apple product I’ve owned since then has had crappy batteries. what’s the deal?
