Apple says its Apple Watch Series 3 offers "all-day battery life" with 18 hours of usage, but in some cases, the LTE model's battery will drain more quickly.

The 18-hour usage metric includes 90 time checks, 90 notifications, 45 minutes of app use, and a 30-minute workout with music playback, and on the LTE model, it includes 4 hours of LTE connection and 14 hours of connection to iPhone via Bluetooth.


When talking on the Apple Watch or working out, though, battery life is shorter when using an LTE connection.

The Series 3 Apple Watch offers 1 hour of battery life when talking to someone on the phone over LTE, or three hours when connected to the iPhone.

For audio playback when connected to the iPhone, the Apple Watch battery will last for up to 10 hours, which is an improvement over the Series 2 (6.5 hours). Apple does not mention how long the battery will last when listening to music over an LTE connection, but the Apple Watch Series 3 will support streaming from Apple Music without an iPhone.

When it comes to workouts, the Apple Watch battery will last for up to 10 hours during an indoor workout with an iPhone nearby, but that number drops for an outdoor workout sans iPhone. With just GPS activated, the battery in the Series 3 Apple Watch will last for five hours (the same battery life as the Series 2 with GPS on), and when connected to LTE and GPS the battery will last for four hours during an outdoor workout.

According to Apple, the Apple Watch Series 3 will charge to 80 percent in one and a half hours and 100 percent in two hours using the included Apple Watch Magnetic Charging Cable. These charging numbers are identical to the Apple Watch Series 2.

Apple's Series 3 Apple Watch models will be available for pre-order on September 15, with the device launching on September 22. Pricing starts at $329 for non-LTE models, and $399 for LTE models.

So let’s say I really want the SS watch but don’t want to activate a data plan on it, the battery will only last 14 hours? I would get the non-cellular watch but it only comes in aluminum

The next watch will have a bigger screen and therefore will have a bigger battery and can them have a FaceTime cam. They’re gonna do it one day. For people to think this design is the only way the watch will look need to watch the keynote again and see how far the iPhone has come.

Apple did a great job on this Watch

They succeeded where Samsung and others failed.

But this battery life is a showstopper for me. cellular is a nice to have.

The app,e Watch is about fitness. The more focused Apple gets around that, the better the product will be.

Agreed on that last line. The watch isn't good for looking up something on the internet (can blame siri for that), reading emails, or getting news, which is a big parts of my phone activity. I'd love it if the watch were good at these tasks, but all I really do with it is check text messages (but grab the phone to respond as I don't like dictating aloud) and use it for running. Series 2 has definitely been nice as an all-around daily work watch and fitness wearable.

They have for sure outsold Samsung, but the Gear S3 does have amazing battery life.

Haha this why I am not convinced about LTE on the watch. 1 hour talk time? On the feature (making phone calls on it) that was advertised? Cue in people moaning and groaning about it in the next few months.

I'm not planning to get this watch - I'll stick with my Series 1.

I've got to say, though, that demo was a little impressive. Not the fact that she was calling from the middle of the lake, but - the lady's watch picked up her voice really well, considering its relative position as she paddled. Maybe all the watches can do that... but I still tend to hold mine up to my face (on the rare occasions) when I talk into it. I'll have to stop doing that, and see how well the microphone works.
