Pixel Watch 4 is the most complete Android smartwatch in 2025 for people who want a bright, easy-to-read display, deep Google integration, and a watch they can actually keep for years.
You get slimmer bezels, stronger performance, better battery efficiency, emergency Satellite SOS (LTE models), and rare-for-a-watch repairability.
If you’re on Android and care about both day-to-day smarts and long-term value, this is the one to beat.
Google Pixel Watch 4 Review:
What’s New and Why it Matters:
Actua 360 display:
The domed OLED now pushes up to ~3,000 nits, so stats stay visible in midday sun.
Bezels are slimmer, giving more screen without feeling bulkier on the wrist. Available in 41mm and 45mm.
Wear OS 6 + Gemini:
Faster UI, smoother animations, improved Tiles, and raise-to-talk Gemini so you can speak your request without a wake phrase.
It feels more “watch-first” than past Wear OS builds.
Safety upgrades:
New Satellite SOS on LTE models for off-grid emergencies, with a guided connect-to-satellite experience and two years included after launch (availability varies by region).
Longevity focus:
Official parts and guides make screen and battery replacements practical through iFixit/partners, which is rare in this category.
Design, Comfort, and Display:
The circular, minimal look is intact but refined.
The domed Actua 360 screen really is the headline: colours pop indoors, and outdoors, you can glance-read pace, HR, and turn prompts without squinting.
The smaller 41mm now feels less cramped, thanks to the larger active area; the 45mm gives runners and cyclists a bit more map and data room without getting chunky.
Both sizes are IP68 + 5ATM for swimming.
Who will love it: anyone frustrated by dim screens or thick bezels on earlier models, and small-wrist users who still want legible data.
Performance and Software Experience:
Under the glass, the Snapdragon W5 Gen 2 + co-processor keeps things snappy.
App handoffs (Maps → Messages → Wallet) are smoother, and the UI polish in Wear OS 6 makes basic tasks feel effortless.
Gemini does a better job with quick answers, dictation, and reminders; raise-to-talk is one of those little features you end up using all day.
It still isn’t perfect (occasional inconsistency), but the direction is right.
Practical tip: if you use Assistant/Gemini often, add the voice shortcut to a long crown press and enable raise-to-talk for a phone-free feel.
Health and Fitness Tracking:
You get the essentials—optical HR, SpO₂, ECG, skin temperature, fall/crash detection, dual-band GPS—and Fitbit’s software continues to make sense of everything with clear sleep, readiness, and stress trends.
Auto-workout detection kicks in faster than before, and route tracks look cleaner thanks to the dual-frequency GPS.
This is still a wellness-first watch, not a lab device; for medical concerns, always consult a clinician.
Who it suits: everyday runners, gym-goers, and commuters who want reliably tracked workouts and tidy summaries, plus strong sleep insights.
Battery Life: our real-world expectations
Google rates ~30 hours (41mm) and ~40 hours (45mm). In mixed use with always-on display, LTE off, and a couple of GPS workouts, most testers are seeing ~36–48 hours on the 45mm and solid “full day plus morning” on the 41mm.
A quick top-up before heading out is often all you need: charging to about 50% in ~30 minutes has been typical.
If you turn off AOD and limit background AI, two days is a realistic timeframe for the 45mm.
Battery-saving profile (easy wins):
-
Keep AOD on a schedule (work hours only).
-
Set Maps to haptic-only prompts.
-
Restrict Gemini background access when you don’t need it.
-
Use Wi-Fi at home; LTE only when you’re out.
Safety and Satellite SOS:
For hikers, cyclists, and travellers in patchy coverage, Satellite SOS is the standout.
When the watch can’t find cellular, it guides you with on-screen arrows and haptics to align to a satellite and send an SOS or preset message.
It’s an LTE-variant only, region-limited, and includes two years at no charge after launch—check coverage before you rely on it.
Tip: Create a short emergency profile and preset messages in the app so you’re not typing when stressed.
Repairability and long-term ownership:
This is a quiet revolution: official parts, published guides, and a warranty stance that doesn’t punish careful self-repair.
Is the screen or battery getting tired in two years?
Replace it and keep the watch going—better for your wallet and the planet.
Use authentic parts and reseal properly to protect water resistance.
Practical setup advice: (day one)
-
Choose your size by battery: small wrists? 41mm is finally roomy enough; heavy GPS user? 45mm stretches longer.
-
Tune notifications: start lean (calls, messages, calendar). Add more only if you miss them.
-
Tiles to keep: Weather, Next event, Fitness (HR/sleep/readiness), and a custom Shortcut tile.
-
Workout defaults: dual-band GPS On, auto-pause Off for runs, haptics On for turns.
-
Safety first: set up emergency contacts and test location sharing at home.
Pixel Watch 4 vs competitors: (quick context)
-
Galaxy Watch 8/8 Classic: Samsung goes deeper on coaching and some body metrics; battery can edge ahead in lighter use. Pixel feels cleaner with Google apps and Gemini, and gets Satellite SOS on LTE.
-
Apple Watch Series 10: unmatched app ecosystem and tight iPhone integration; on Android, Pixel is the obvious pick and now rivals Apple on display punch and daily polish.
-
Garmin (Fenix/Epix/Forerunner): still better for multi-day GPS and athlete-grade training metrics. If you need a week-long battery, that’s Garmin’s turf.
Specs:
| Pixel Watch 4 (41mm) | Pixel Watch 4 (45mm) | |
|---|---|---|
| Display | Domed Actua 360 OLED, adaptive refresh (up to ~3,000 nits) | Same |
| Sizes/Weight | Smaller, lighter for small wrists | Larger, slightly heavier |
| Processor | Snapdragon W5 Gen 2 + low-power co-processor | Same |
| Memory/Storage | 2GB RAM / 32GB storage | Same |
| Battery (rated) | Up to ~30 hrs | Up to ~40 hrs |
| Charging | Fast magnetic; ~50% in ~30 min (typical) | Same |
| Water/Dust | 5ATM + IP68 | 5ATM + IP68 |
| GPS | Dual-band (L1+L5) | Dual-band (L1+L5) |
| Health sensors | HR, SpO₂, ECG, skin temp; fall/crash detection | Same |
| Connectivity | Wi-Fi, BT; optional LTE | Wi-Fi, BT; optional LTE |
| Safety | Satellite SOS (LTE, regions vary; 2-yr included) | Satellite SOS (LTE, regions vary; 2-yr included) |
Who should buy it:
-
Android users who want the smoothest Google experience on the wrist.
-
Everyday athletes who value accurate tracking, great visibility, and clear recovery/sleep trends.
-
Travellers and hikers who want Satellite SOS as a safety net (LTE + region permitting). Skip it if you need multi-day GPS expeditions without charging (look at Garmin), or if you rely on niche smartwatch apps not yet on Wear OS.
Final Verdict:
Pixel Watch 4 refines the design, strengthens the core features, and adds meaningful safety and longevity. It won’t outlast a Garmin on a thru-hike, but for daily life, training, travel, and smart assistance, it’s the most balanced Android smartwatch you can buy in 2025.
