I Tested the Pixel Watch 4: Design and Function, Working in Harmony

Google Pixel Watch 4

$350 at Google

Pros

• Emergency satellite connectivity
• $350 (starting) price
• Dual-band GPS
• Hands-free Gemini voice assistant
• Ultra-fast charging (50% in <15 min)

Cons

• Health coach not yet available
• Battery lasts just over 24 hours
• Watch bands are hard to maneuver

I was genuinely excited when I first heard about the Pixel Watch 4. Google says it's the biggest update yet for the smartwatch, promising better everything -- from battery life to display. It also introduced not one but two powerful assistants: Gemini and a true Fitbit health coach -- the kind of built-in concierge I've been wanting in a smartwatch.

But the problem with big promises is that they can lead to unrealistic expectations and potential disappointments. And while I'm still waiting on that health coach's promise to materialize, everything else I've tested so far does, in fact, live up to the ideal I'd built up in my head, making the Pixel Watch 4 a serious contender in the smartwatch world.

At $350, the Pixel Watch 4 packs in plenty of "luxuries" once reserved for pricier sport watches, including dual-band GPS for more accurate location tracking, satellite connectivity for off-the-grid emergencies and a frame that's easy to repair when needed. The cherry on this well-rounded sundae? A truly competent, hands-free AI voice assistant that won't leave you screaming at your wrist.

In a crowded Android watch world where most devices can nail the basics, advanced health features are what increasingly set them apart. The Pixel Watch 4 hits a sweet spot between universally appealing design, seamless compatibility with the Android ecosystem, potentially life-saving safety features and robust health and fitness tracking via the tried and true Fitbit app.

If Google can deliver a health coach that's as capable as Gemini and turn raw data into actionable guidance, the Pixel Watch 4 could leap into a league of its own. But for now, here's what's already tried, true and worth your attention on the Pixel Watch 4.

Better battery built for 24/7 health tracking ambitions

As much as I love collecting data about my body, I have to admit -- I'm not a fan of sleep tracking. Aside from the discomfort of wearing a watch to bed (which I mostly got over with the Pixel Watch 4), I'm a creature of habit and like waking up to a fully charged watch and phone.

But the reality is that many key health features in wearables now depend on collecting data while you sleep. That's true for Fitbit, too, especially with its Readiness Score, which -- as the name suggests -- rates how ready you are to take on the day by analyzing recovery indicators such as sleep quality, heart rate variability and resting heart rate. It doesn't appear until you've logged about a week of consistent sleep data.

According to my Pixel Watch, my current score is "low," meaning I should be resting and recovering instead of writing this review. But just because I'm running on low doesn't mean my battery should be -- and older Pixel Watches wouldn't have even lasted long enough in the day to tell me that.

The Pixel Watch 4 changes that. Google claims up to 30 hours of battery life for the 41mm model I've been wearing and 40 hours for the larger 45mm version. In my real-world testing, which included a full day of use, one night of sleep tracking and one 40-minute outdoor run, the Pixel Watch 4 delivered on this promise, but with one major caveat. It automatically switches to Battery Saver mode at 15%, which turns off the always-on display, pauses background activity and delays some notifications. So yes, it technically hits the 30-hour mark, but if you let the battery run its full course without that safety net, it's closer to 26 hours. Not a deal-breaker, but I'd prefer if it'd ask before automatically throttling features.

What's been even more practical than the battery boost is its charging. The Pixel Watch 4 debuts a new charging dock that Google says can take the watch from 0 to 50% in 15 minutes and reach a full charge in about an hour. In practice, I found it even faster. Using a 20W charger, I hit 60% in 15 minutes and 100% in roughly 40 minutes.

The real-world benefit: less time off my wrist. One night, I realized the watch was at 5% just as I slipped into bed. Instead of skipping sleep tracking altogether (which I would've done before), I dropped it on the charger for five minutes and got enough juice to make it through the night.

Better processing power and easier repairs

The Pixel Watch 4's improved battery life comes down to hardware and software. This year, Google's using a dual-chip setup: a Snapdragon W5 Gen 2 paired with a Cortex-M55 co-processor, along with Wear OS 6 optimizations that claim up to 10% better performance and efficiency over the previous version.

And if the battery ever does give out completely, Pixel Watch 4 owners won't be out of luck. Google made the battery and display replaceable, meaning authorized service providers can handle repairs without turning it into a complete teardown. That's still rare in the smartwatch world, where cracking open the hardware usually isn't even an option (and it goes without saying, please don't try this yourself).

Satellite connectivity and advanced GPS for less

Another standout feature on the Pixel Watch 4 is emergency satellite connectivity (cellular model only). It lets you reach emergency services even when you're off the grid. We've seen this on smartphones, including the Pixel and iPhone, and recently on high-end watches such as the Apple Watch Ultra 3 and Garmin Fenix series, both of which cost more than twice as much as the Pixel Watch 4. That makes this watch the lowest-cost way (as of this review) to get an extra layer of connectivity on a smartwatch that's always attached to your body. 

I haven't had to use it in a real emergency, but I did try the demo in the "Safety & Emergency" settings. It walks you through connecting to a satellite and simulates the questions emergency responders would ask to send help. It's worth doing ahead of time so you're not figuring it out during an actual emergency.

Both the cellular and Wi-Fi models also come with dual-band GPS, which makes tracking outdoor workouts more accurate, especially in tricky environments like dense city streets (where tall buildings can bounce signals) or remote wilderness trails.

Gemini on the Pixel Watch 4

But perhaps the most significant update on the Pixel Watch 4 isn't in the specs; it's in how you interact with it. The watch has traded in its "OK Google" for Gemini, Google's AI voice assistant that debuted on the Samsung Galaxy Watch 8. I wrote about how much I enjoyed using it on the Galaxy Watch, and on the Pixel Watch 4, it may even shine brighter thanks to its raise-to-talk functionality (no prompt needed) and deep integration across all the Google apps.

I can ask it to send a text in a foreign language and follow up multiple times without repeating my original question. Most importantly, it usually gets things right on the first try -- whether it's starting a workout or looking up a quick fact online -- without just dumping a link I have to awkwardly open on the tiny watch screen (looking at you, Siri).

I didn't realize how much convenience could change how I use a voice assistant on a watch until I discovered raise-to-talk. Having to press a side button (which you can still do) or remember a specific "Hey" or "OK Google" command was holding me back. Once I maxed out the motion and voice sensitivity in the Gestures settings, it became way more responsive, and with barely any false triggers.

Not only is Gemini a solid AI assistant, but being able to raise my wrist and start talking to it Dick Tracy-style has me interacting with it more than on any other watch I've tried (Gemini-powered or otherwise).

Peak health and fitness, with more to come

Even before Google's fourth-gen watch came into the picture, the Pixel Watch had already made a name for itself in terms of robust health and fitness features. Its Fitbit integration goes above and beyond the basics with potentially life-saving emergency tools such as ECG and irregular heart rhythm detection, crash and fall alerts and an FDA-approved loss pulse detection feature that's layered on to its full suite of workouts and training options. There's even access to personalized training plans and on-demand workouts through the $10/month Fitbit Premium subscription.

But Fitbit's health and fitness ecosystem's true benefit is in its intuitive UI. The Pixel Watch 4 keeps relevant stats in the forefront, whether it's on the watch screen or the Fitbit app, compared to other trackers that hide relevant metrics under sheets of raw data that you're left to interpret yourself. 

While on a run, I like how the display changes color based on my heart rate zone rather than trying to read the actual number while I'm pounding uneven pavement. The Readiness Score (while not always realistic) is pretty accurate. I appreciate that it actually breaks down the factors behind each score, instead of just tossing out a number with no explanation like other devices do. With how good Fitbit is at contextualizing your data, I'm even more curious to see how it executes a health coach that'll live inside your watch. 

Google says the coach will roll out to the Pixel Watch 4 (and newer Fitbit and Pixel Watch models) later this year alongside a redesigned Fitbit app and will be accessible to Fitbit Premium subscribers. Unlike Samsung's Running Coach or Apple's Workout Buddy, this coach isn't limited to workout data. It's designed to connect your activity, sleep and recovery metrics to give a complete picture of your health. In theory, the coach will let you ask questions like, "How do I improve my VO2 max?" or "Should I get an extra hour of sleep or work out tomorrow morning?" If it delivers, it could be the missing thread that ties all of the Pixel Watch's health tools together -- from personalized running programs and body-response sensors to emergency alerts -- into one cohesive, actionable experience.

A design that fits any style

The Pixel Watch 4 exudes simple elegance. It has an all-screen design that curves from the aluminum frame like a polished pebble. It's not drastically different from its predecessors, but the screen has noticeable upgrades, including reduced side bezels that expand the screen real estate and a brighter display. The Pixel Watch 4 can reach up to 3,000 nits of peak brightness, meaning I had no trouble viewing it from every angle or even under direct sunlight during my runs. The Gorilla Glass-covered screen has also held up well so far, with no scratches.

My only real criticism is the band system, which remains the same as last year's. It uses a button mechanism to slide the bands in and out but requires near-surgical precision to operate smoothly. It also limits your options mostly to Google's own proprietary bands.

The Pixel Watch 4's UI

The display upgrades shine even more with Material 3 Expressive on my wrist. The UI doesn't just look better; it feels more fluid. Buttons and tiles hug the screen's curve, colors adapt to your watch face and you can see more text because the layout molds better to the rounded screen. The result is a closer match to the look and feel of your Pixel phone, giving the watch a more unified, polished appearance.

Pixel Watch 4 bottom line

Even without the AI health coach, the Pixel Watch 4 is one of my favorite Android watches. With the battery boost, satellite connectivity, brighter screen and just enough improvements, it's an easy upgrade for anyone with an older Pixel or Android watch. Just maybe not a recent model like the Pixel 3, since many of the headline features, including Gemini and the Fitbit coach, will be rolling out to older watches over time.

For me, it hits the sweet spot between sleek, minimalist design, smart features and robust health and fitness tracking, tied together by the elaborately constructed bow that is Gemini. The voice assistant finally makes hands-free navigation possible on a tiny watch screen, where I don't want to do heavy lifting. Gemini lets me get things done and answer questions even when my phone is out of sight.

The $350 price also makes it relatively accessible when you consider some of its luxury features, such as satellite connectivity and ECG. It's not cheap, but reasonable for what you get.
