Apple Watch Battery Life: 18 Hours In Normal Usage, 72 Hours On Power Reserve Mode

Apple Watch’s biggest concern was rightfully the battery endurance, and as announced in the keynote today, the wearable is capable of lasting around 18 hours on mixed usage, which isn’t bad at all. More details on the battery, right after the jump.

The much discussed aspect of the Apple Watch pre-announcement has been the battery life on the device and how Apple could be the one to bring in something new to the game. Post-announcement, the Cupertino based company is being referred to by some as the guy that walks into a bar for its effort on the watch which saw the company skipping the looming ‘why’ question.


A watch that lasts 18 hours while being used as normally as it would be once users get around the whole tinkering bit after the first week or so is a pretty decent deal. Not to take anything away from the Apple Watch, but 18 hours isn’t spectacular either, with the competition coming in with numbers that can out-gun the Apple Watch any day, albeit being low on features and performance. Officially, Apple has broken down these 18 hours of usage where the time was checked 90 times, 90 notifications were received, apps were used for 45 minutes, and a workout routine that lasted for 30 minutes with music being played on the wearable via Bluetooth. These are official Apple stats, but of course, the battery life will vary depending on the user.

Apple has acknowledged that these ratings were reached using the 38mm version of the Apple Watch as a test-bed, and that the larger 42mm watch is likely to experience a slightly longer battery life, given the marginally larger battery on the device; kind of like the iPhone 6 Plus, so to say.

Turns out, the rumor which was going around the Internet claiming that Apple would be throwing in a ‘Power Reserve’ mode was not without substance after all, as the Mac maker announces the inclusion of the feature, extending the battery life on the wearable to a whopping 72 hours. The Power Reserve mode kicks in automatically as soon as the battery gets low.

A full charge of the Apple Watch (38mm) will take around 2.5 hours, which is fine, but given the size of the wearable, and the time it takes to charge an iPhone, you have to scratch your head at this one.
