I’ve spent over a month with the Pixel Watch 4 as my daily (and nightly) companion. While it’s still one of my favorite Android watches out there, the honeymoon phase is officially over and some of its blemishes (and scratches) are starting to show.
The look and feel still holds up to the test of time; It is smooth, understated and comfortable to wear. But it’s the intuitive UI, seamless syncing with my phone, and the way it fits so naturally into the Android ecosystem that keep me coming back to it. Paired with my Pixel 9 Pro, notifications arrive instantly, health data syncs as soon as I open the app, and Wear OS updates are delivered faster than other watches.
Although the Pixel Watch 4 remains one of my favorite Android watches of 2025, there are some literal chinks in its armor that are starting to surface with long-term, real-world use.
Gemini is hip in my conversation
I’ve already raved about how useful it is Google’s new AI assistant is on a smartwatch. It handles complex requests in natural language (no robo-voice required), understands follow-up prompts without requiring me to repeat the original question, and can even translate text on the fly. On a smaller watch screen, where typing and reading long responses is tiring, the Gemini truly provides a more seamless hands-free experience.
The Gemini Pixel isn’t exclusive to the Watch 4 (it comes to new Android watches with Wear OS 6), but it takes it a step further by letting you talk to it instantly: no buttons, no wake-up sounds.
The first week, I went full-on Dick Tracy, asking my wrist every stray thought that crossed my mind. I loved that it read the answers out loud so I could cook or scold the kids without looking down. It was short lived.
Google’s AI voice assistant Gemini on the Pixel Watch 4 can often be mistakenly triggered with its wake-to-wake functionality.
After a few weeks, Gemini has mostly faded into the background. Part of it is from wearing off the novelty, but mostly it’s because the Gemini misses the mark when I actually need it. It turns out that having an assistant so readily available isn’t always as convenient as it sounds.
Sometimes I have to exaggerate the wrist-raising to get it to listen, other times it wakes up unexpectedly because I’m gesticulating with my hand. enthusiastic I am a Latin woman. Often, there is a noticeable delay before it even responds. Case in point: I was on a video call with my manager when Gemini suddenly shouted out an answer… neither of us had asked anything. This makes the watch look like it’s listening and ready to interject at the worst possible moment.
You can turn off waking and switch to a button press or on-screen activation. But for now, I’m leaving it at that, hoping that with more time Gemini and I can find a rhythm — and that it learns not to talk to me.
Apparently, I’m testing the stability of the walk
I love the Pixel Watch 4’s domed circular screen. It’s small and elegant and looks good with any watch band (elegant or sporty). Nearly 180-degree visibility makes it easy to read at a glance without needing to angle your wrist, and the 4,000-nit display is readable on bright midday runs. I’m using the 41mm model (it also comes in 45mm), and it’s comfortable enough to wear 24/7. During the day, I’d forget I was wearing it because it’s so thin; At night, the bubble curtain is a touch more noticeable against the pillow, but not enough to disturb my sleep.
The downside of a watch that’s essentially all screen is that it’s more exposed to the realities of life (mine, especially). As an outdoor enthusiast and mother of three kids whose personal hobbies include testing the limits of gravity, I can’t be too precious about my technology, jewelry or anything else. Form over function is where I’m at.

So yes, I already managed to scrape the custom 3D Gorilla Glass 5. I wish I could tell you what an epic adventure it was, but I didn’t really notice until I shot the review video. The scratch is definitely visible and worth considering if you plan to use the watch for more rigorous activities. You might want to invest in a screen protector, which admittedly defeats the whole sleek, minimalist aesthetic, but here we are.
The strap system requires a learning curve. This is the same process as the previous model, but requires adjustment by pressing the release button while sliding the band. If you’re planning to swap to a third-party band to dress it up (or down), know that it will take a few tries before it feels natural.
Fitbit’s app is a joy, but I’m still not sold on Coach
The Pixel Watch 4 packs every major health and safety feature you’d expect: ECG, irregular heart rhythm detection, crash and fall alerts, and a FDA-approved low pulse detection feature. But none of them are what I interact with on a daily basis.
The Fitbit ecosystem is where the watch really shines. The UI is clean, intuitive and breaks down your data into easy-to-digest snippets on both the watch and the app. I love waking up to my health summary, including my sleep and readiness scores (even if they’re disappointing at times). It misread a late-night couch session as sleep once or twice, but overall, its tracking felt accurate. It even flagged a dip in my HRV that night as I was clearly battling some sort of bug. Coupled with a low readiness score, this gave me the nudge I needed to take it easy and recover. It never fully developed into anything serious, which I credit the Pixel Watch for.
During a workout, the numbers on the Pixel Watch 4 change color to match your heart rate zone.
The Pixel Watch 4 does all the fitness basics, but goes above and beyond the details For example, instead of having me search through the screen for my heart rate zone, the watch changes the color of my workout interface to match my heart rate zone so I can quickly see my workout.
I’ve always thought the Fitbit app was the most intuitive in the wearable space, but after testing the redesigned version (rolling out publicly next year), it might be the best. Instead of focusing on one day, it now gives you an entire week’s view of your fitness data, which feels much more realistic. If I skip a workout, the broader context keeps me from feeling defeated and strangely motivates me more.
The redesigned Fitbit app interface includes a weekly view of your exercise goals.
The biggest update, though, is behind the $10/month Fitbit Premium paywall: Fitbit CoachAn AI chatbot that is supposed to help translate your data into actionable instructions.
Setup will require you to answer a series of questions about your goals, equipment, and time commitment. My goal was to get the most bang for my buck out of the workouts within my time constraints. Coach created a custom plan to meet my needs, although plugging similar information into the free version of Gemini on my phone produced nearly identical suggestions. The difference is that the coach gave me video examples of the workout moves, which was a nice touch.
Fitbit’s new “Coach” feature can create custom training plans with video examples for each step.
Coach also has access to your habits and health data to make changes on the fly, which is really useful. This flags that working after 9pm is counterproductive for me based on my sleep patterns and energy score. It suggested skipping my workout on those bad sleep days and opting for a nap instead (which I didn’t have time for, but still appreciated the rest allowance).
But there are limitations. Unlike the Gemini, which I can call up anytime on my watch, the Coach is only available on the Fitbit app on my phone, making the experience feel oddly passive. I hope it coaches me during workouts and tells me to hit a target zone or tells me when it’s time to move on to the next exercise in my training plan.
Coach also can’t offer medical advice (which is a good thing), and when I tried baiting it to do so, it correctly told me to talk to a doctor. Still, handing over so much health data to an AI makes me a little uneasy because I’m not exactly sure what it might be used for down the line.
To be fair, Coach is still in beta and it’s supposed to adapt as you learn the habits. So, it may improve over time, and the version you get may look very different from what I’m previewing.
The 41mm Pixel Watch 4 has a battery life of around 30 hours.
Battery life is ok
Over the past month, my take on batteries hasn’t changed much. That’s a welcome improvement over the last generation, but that 30-hour mark still comes quickly — usually in the middle of my second day when I’m nowhere near a charger. I’ve fallen into a routine of micro-charging 10 minutes before bed or right after waking up. That’s usually all it takes to get through a full night of sleep tracking.
Google claims it takes 60 minutes to fully charge, but in my experience, it’s closer to 40 minutes.
Some of its best features I have yet to use
Even if I manage to scratch the screen into oblivion or crack it outright, I have peace of mind knowing that Google has made this watch easy to repair. The display, battery, and other components can be swapped out without buying a whole new device — just don’t try to DIY it This level of repairability is rare in the smartwatch world, and it could save me shelling out for a brand new watch down the line.

I’m testing the LTE model, which can communicate with emergency services via satellite if you’re off the grid and need help. I’ve never been without a cell signal (or in trouble, thankfully), but it’s a nice safety net, especially for the price. Similar satellite-enabled watches, eg Apple Watch Ultra 3 or Garmin’s Fenix 8 ProPrices are over $700, while the LTE version of the Pixel Watch 4 starts at $450
stop thinking
After a solid month together, here’s where I landed: If you’re looking for an Android watch that does everything right, the Pixel Watch 4 is a solid pick. The 41mm battery still needs work (the 45mm should be better), and if you’re just buying it for the Fitbit Coach, I’d hold off: it’s promising, but not quite there yet.
Even without Coach, though, the redesigned Fitbit app alone is enough to get excited about. Add in the sleek design, ease of use, and seamless integration, and the Pixel Watch 4 puts this watch at the top of my list. And if Google finally nails the coaching aspect, it will be the cherry on top of an already well-rounded sundae.
I’m sure in another month I’ll have more gems and quirks to report. That’s exactly how it goes with things you wear day after day, especially now that they’re constantly adapting to your habits.
