Apple Watch to have an 'all-day' battery life, check out the official breakdown and charging times

Apple Watch lets you pay for stuff with it, open your garage door, answer calls, check through the security at the airport, and even unlock your hotel door for you, but how long will its battery last with all that jazz? 

Well, the Apple Watch has an 'all-day' battery life, according to the company's presentation just now, or, more precisely, up to 18 hours on a charge. Of course, this is mixed usage and standby scenario, which would likely translate in the fact that you will be able to plough through the working day with moderate Apple Watch tinkering, then get home and stick its magnetic charger on the back before the battery gives up the ghost completely.

Here's how many hours of each individual usage scenario you will be getting out of the new timepiece, as per Apple's official estimates:

  • 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.

It's interesting that the company disclaims how "Apple Watch battery performance claims are based on test results from the 38mm Apple Watch. A 42mm Apple Watch typically experiences longer battery life," which might come as proof that the larger, 42mm timepiece would also carry a bigger battery.

LOL.. When Tizen is doing 2 days easily, and in some cases upto 3 days.

I can get easily 5 days on gear. All you have to do is switch off the device at night. My gear uses up about 18% of battery per day. So it's very easy to get a few days out of it. Even the heaviest users should get 2 days easily.

lol. take notes apple, Neros got the right idea.

18 hours eh? We will see about that!

Ah the official numbers, always a factor of 2-3 higher than actual numbers.

Yeah, but a lot of people on this site were saying 2 to 4 hours. And seeing as no one on this site has any actual hands on experience with the device then I think arguing at this point is somewhat pointless.

That was continuous use. Whereas this is mixed use

Nah haven't you seen people carrying around those elegant power banks to charge their iPhones, really compliments the slimness of the phone.

Not really. I don't listen to rumors, but one source did say with constant onscreen time the device would last 2.5 hors at best. Now, I can't see where you would need to have the display on constantly. But I know for a fact, I have my device on for my full workout and it seems not to effect battery life very much. Apple can make claims, but tests will show for sure. Even if it lasts a day, 349 is too high for such limitations. I paid 299 for my Gear S and it functions 100% without being tied to a phone, including making and receiving calls and it last 2.5 days on a single charge.

Yeah, but you forget my friend, it doesn't have an Apple logo on it. And I don't care about rumored reports from unknown sources. If you believe in those reports then you'll look foolish just like everyone defending an unreleased iPhone by bragging about sapphire glass. Not to say that some of those reports can't be legitimate, but you have to take everything with a grain of salt.

The Gear S is a very underrated phone. The iWatch was being touted as a sport watch, they even named the "cheap" model Sport, yet is is lacking in to many areas for that. The Gear S not only caters better for training, but I can leave my phone at home and have security if I have a problem I can call someone to help me out.

Absolutely. 48 hours with 20 secs total time check per hour. Do the math, that's a whopping 16 minutes of watch face time to get the battery depleted. Oh yeah, that shuts up everyone. Pain in my stomach from laughing. Waking up the watch must really drain that battery, or else there is no reasonable explanation why simply checking the time a few times per hours kills a battery that fast.

Umm.... if all anyone ever did with this watch was check the time then I don't think it would qualify as a smartwatch. Check out the commercial that phone arena has posted for the device, there are lots of current apps plus many more on the way that require more than just a few seconds every hour to make use of the device. I don't care much for Apple so you can't say I'm an iSheep, I'm simply saying that people were making uneducated statements about something they knew nothing about... something you apparently excel at.

Way to miss the point. Simple tasks such checking the time for a mere 4 secs (per check) already appear to have a massive impact on the battery life, that's the point. It's the most basic and primary function of a watch, even a smartWATCH. There are already smartwatches out there that can have the clock displayed for days... and allow you to use apps, get notifications etc.

Brace yourselves the innovative battery technology is on it's way... Sarcasm intended.

Haven't they removed half the sensors out of it, like the blood pressure sensor or sth?

18 hour on average use is more like 3/4 day.

No thanks. Battery life on smartwatches is generally not something to smile at but this is a definite no no.

Guys...guys...its a first gen product. Samsung had 2 years to figure out battery life before Apple Watch...So far its been lackluster...Even Android Wear...

Sorry but no. Apple had two years to learn from everyone else's mistakes and they present the world with this watch. People really like different styles of watches more so than phones I believe. The pricing is outrageous in comparison to Android Wear devices as well. I'll be waiting for the Apple Watch 2 after the 1s where they redesign this device and start from scratch. They could've at least offered a circle watch option.

Apple Watch has been in the making since 2010. That doesn't mean it will be successful or have the features everyone wants and that is battery life. We will reach a point where technology provides us solar technology to give us unlimited battery, but best believe Apple is working around the clock to make this happen. Kinetic watches happened because of result of deep rooted engineering. Their will be a break through within the next few years. Their will always be pain with the first genwatches. Ask Samsung...Look at Android Wear...The list goes on... Just because Apple charges more than the competition doesn't mean it will always outperform in battery life. Right now I believe Apple Watch is the slickest smartwatch available.

wait.... this is technically apples 2nd watch... they unvieled this years model last year... so they have had plenty of time to improve on last years model they showed us but never sold.

Please, stop. They had years to get it straightened out while other smartwatches were on the market. Stop it.

18 hours of "mixed use", Basically ~18 hours of standby time...
