APPLE WATCH SERIES 3

The Good Cellular connection works well for phone calls, email, Siri and messages. Music now syncs more easily. Improvements in fitness tracking and added watch faces. Adds barometer to GPS and swimproofing. Same overall size as last year’s watch.

The Bad Battery life takes a major hit when making calls or during GPS workouts. 42mm cellular model is expensive, and that’s before monthly wireless service and Apple Music fees. Still requires an iPhone to set up and pair with.

The Bottom Line The Apple Watch Series 3 is the best overall smartwatch you can buy, but battery limitations and add-on fees keep it from being a must-have upgrade.

I spend a lot of time with a phone in my face.

That's why I was attracted to the original Apple Watch. It sold the fantasy of a watch-as-phone: An iPhone Micro on my wrist. One less gadget.

But because the Apple Watch had to be paired to my iPhone to do anything constructive, the phone never went away. I just ended up alternating between staring at two different screens.

That's changed now, kind of, with the Apple Watch Series 3 ($469.99 at Amazon Marketplace). It adds built-in support for cellular connectivity. The full Dick Tracy communicator, much like Samsung, LG and others have already tried

I've been testing the Apple Watch Series 3 for a week, using it as my phone, fitness tracker, Apple Pay wallet and iPod. And, yes, I've even been making phone calls with it. It lets you stay connected in those few places where even phone addicts may skip the phone: Going for a walk around the block. At the gym. At the pool or the beach. In the bedroom, while you're trying to fall asleep.

The irony of having a watch that's a phone means you're more tethered, not less. But you're more limited, too. For better or worse, this isn't a full micro-iPhone. There's no camera. It's not easy to respond to emails and messages. I can't really tweet, read stories or watch videos. And you still need an iPhone to set it up and get the most out of it.

Other caveats abound. Battery life limitations severely curtail phone calls and GPS-aided workouts. There's still more Apple needs to do to maximize fitness tracking and streamline the software. And you'll be paying monthly subscription fees (for wireless service and for Apple Music) to get the most out of it.

All that said, the Apple Watch Series 3 is the best phone watch I've tried. Setup is easy, and toggling from cellular to Bluetooth and back again is mostly seamless.

But I still find myself reaching for the iPhone.

(Editor's note: See the "Connection quirks" section below for information on a Wi-Fi issue on the cellular Series 3 models. More testing is still to come. Ratings are provisional until those tests arecompleted.)

Cellular, and how it works

The big upgrade on the Apple Watch Series 3 is that it adds always-connected cellular functionality. It works works on all major cellular carriers -- in the US, at least -- which is nice.

Cellular supports data and voice -- where there's the proper coverage, of course -- and the Watch uses the same number as your iPhone. The catch, of course, is that it costs money: $10 per month in the US, above and beyond your existing wireless fee. And despite the fact that the Watch is designed to free you up from your phone, you'll still need your iPhone to set it up and to install apps. And no, it doesn't work with Android phones.

The Apple Watch communicates to the outside world in three steps. It looks for your iPhone first, pairing via a Bluetooth connection if it's nearby. If not, it tries Wi-Fi (new networks can't be added on the Apple Watch directly, but it syncs and knows networks that your iPhone does). If neither of those options are available -- say, if you're out hiking -- the Watch then enables LTE cellular, which is otherwise switched off to conserve power.

Connecting quirks

Some reviews have noted that the LTE version of the Series 3 has problems connecting to LTE when open Wi-Fi networks are nearby, a bug that Apple has admitted to. Apple confirmed these issues to CNET, too. It's unclear exactly when the problem will be fixed via software update, but I was told it would be soon. (In the meantime, to disconnect from a problem Wi-Fi network, you need to forget the network using your phone.)

I didn't experience those specific issues, but I did have weird experiences with notifications. iMessages sometimes popped in all at once or not at all. And third-party notifications, like Twitter, require your phone to be on and connected to a network somewhere, even if it's not nearby. If it's not, you won't get those pings on the watch. Also, many third-party apps don't currently support LTE connection yet. We'll keep testing this. AirPod connectivity sometimes didn't automatically work, either.

It's unclear how many of these will be smoothed over in software updates. Phone functions were generally fine, and so was email. Messages and notifications came in fits and spurts.

Music: iPod on your wrist, at last

The iPod is gone: long live the new iPod.

Apple Watches could always store music, but they were bad at it: syncing music from a cloud-based Apple Music account was always a time-consuming ordeal. Most other smartwatches are the same. WatchOS 4 now syncs music more automatically, and it's a huge difference. The first time I used the watch, after an overnight charge I found a few playlists and albums waiting for me when I went walking. Others can be added and synced when the watch is charging.

But music is effectively an Apple Music-only proposition. Your iTunes library is always available to you, but for the more sophisticated playlist management -- and real-time music streaming, which isn't coming for a few more weeks -- you need an Apple Music subscription. Spotify, Pandora and Google Play Music subscribers need not apply. Nor, oddly, can podcasts be downloaded to the Watch.   

Wireless headphones are also required. AirPods ($179.57 at Amazon Marketplace) are a perfect fit for the cellular watch, so much so that they feel like an essential accessory. For the most part, they pair instantly. Sometimes, however, I needed to swipe up and select them from the watch control center.

Caveats notwithstanding, the Apple Watch finally feels like that iPod Shuffle on my wrist that I used to wear years ago.
