The best smartwatches in 2026 are the Apple Watch Series 12 for iPhone owners, the Samsung Galaxy Watch9 or Google Pixel Watch 5 for Android, and the Garmin Venu 4 if you want a week or more between charges. The Apple, Samsung and Google watches all launched between July and September 2026, and the first thing that decides between them is the phone in your pocket: Apple Watches need an iPhone, and the Samsung and Google watches are built for Android.
Battery is the second split. The Apple, Samsung and Google watches are charged every day or two, while the Garmin and the $99.99 Amazfit Active 2 run for days. Prices below are the makers’ starting prices; larger cases and cellular models cost more.

| 5 | Garmin Venu 4 | From $549.99 | Up to 12 days | iPhone and Android | Fitness coaching |

1. Apple Watch Series 12: The Best Smartwatch for iPhone
Apple introduced the Series 12 on September 9, 2026, starting at $399, the same price as the Series 11. Its new Health Sensing System and S11 chip measure heart rate every five seconds, all day, and record heart rate variability up to 24 times more often than before.
Those readings feed a new readiness score: a 0 to 10 number each morning, based on recent activity, training load, vitals and sleep score, with a recommendation from Recover to Go For It. The ECG app, sleep apnea notifications, Fall Detection and Emergency SOS carry over, and Siri now runs on Apple Intelligence on the watch.
Everyday battery life stays at up to 24 hours, but an outdoor workout now lasts up to 10 hours, and 15 minutes on the charger adds up to 12 hours. It comes in 42mm and 46mm, in aluminum, titanium and ceramic. Our full Apple Watch Series 12 guide covers which case to choose.
What it does well
- Heart rate every five seconds and a daily readiness score.
- ECG app and sleep apnea notifications.
- 15 minutes of charging adds up to 12 hours.
What to know before buying
- Needs an iPhone.
- Up to 24 hours of battery, so it charges daily.
2. Samsung Galaxy Watch9: Best for Samsung Phones
Samsung announced the Galaxy Watch9 at Galaxy Unpacked on July 22, 2026, starting at $379.99 for the 40mm Bluetooth model. It is the first Galaxy Watch on Qualcomm’s Snapdragon Wear Elite platform, with a 3,000-nit display and a 390 mAh battery in the 40mm case, or 445 mAh in the 44mm.
Health features include a Heart Health Score, Bedtime Guidance, Vitals monitoring during sleep and an FDA-cleared sleep apnea feature. Bedtime Guidance and sleep apnea detection need an Android phone running Android 13 or later, which is why this is the watch for Galaxy phone owners rather than iPhone users.
Samsung does not publish a battery figure in hours for the Watch9. If you want a tougher watch with more battery, the Galaxy Watch Ultra2 starts at $699.99 with an 800 mAh battery and a display rated up to 5,000 nits.
What it does well
- Snapdragon Wear Elite chip and a 3,000-nit display.
- Heart Health Score and FDA-cleared sleep apnea detection.
- Starts at $379.99, below the Series 12 and Pixel Watch 5.
What to know before buying
- Android only, and some health features need Android 13 or later.
- No published battery life in hours.
3. Google Pixel Watch 5: Best for Pixel and Android Battery Life
Google announced the Pixel Watch 5 on August 12, 2026, starting at $399 for the 41mm model and $429 for the 45mm. Battery life is up to 30 hours on the 41mm and 40 hours on the 45mm, the longest of the daily-charge watches here.
The domed Actua 360 display reaches 3,000 nits, Gemini runs on the wrist, and the safety features include Loss of Pulse Detection. Google built it with a repairable design, and it comes in new colors including Fog, Olive and the 41mm-only Canyon.
What it does well
- Up to 40 hours of battery on the 45mm model.
- Loss of Pulse Detection and Gemini on the wrist.
- Bright 3,000-nit domed display.
What to know before buying
- Built for Android phones, not iPhone.
- The 45mm model costs $30 more than the 41mm.
4. Apple Watch Ultra 4: Best for the Outdoors and Battery
The Ultra 4 starts at $799 and shares the Series 12’s Health Sensing System, S11 chip and readiness score in a 49mm titanium case, in natural or black. Its battery lasts up to 50 hours in everyday use and up to 84 hours in Low Power Mode, and 15 minutes of charging adds up to 18 hours.
Satellite communications cover Emergency SOS, Find My and Messages when there is no cellular signal, and every Ultra 4 includes cellular. Our Apple Watch Ultra 4 guide compares it with the Series 12 in detail.
What it does well
- Up to 50 hours of battery, 84 in Low Power Mode.
- Satellite Emergency SOS, Find My and Messages.
- Titanium case with cellular built in.
What to know before buying
- $799, double the Series 12.

5. Garmin Venu 4: Best for Fitness Coaching and Multi-Day Battery
Garmin announced the Venu 4 on September 17, 2025 at $549.99, and it works with both iPhone and Android through the Garmin Connect app. Battery life is up to 12 days in smartwatch mode, so it can track sleep every night without a daily charge.
A new Health status view flags when overnight heart rate, HRV, respiration, skin temperature and Pulse Ox drift from your usual range, and Garmin Fitness Coach builds workouts for more than 25 activities. It also has a built-in LED flashlight, plus a speaker and microphone for calls, in 41mm and 45mm sizes.
What it does well
- Up to 12 days of battery in smartwatch mode.
- Works with iPhone and Android.
- Built-in flashlight, speaker and microphone.
What to know before buying
- $549.99, more than the Series 12 or Pixel Watch 5.
- Fewer third-party apps than Apple or Wear OS watches.
6. Apple Watch SE 3: The Best Budget Apple Watch
The SE 3 starts at $249 in 40mm or 44mm aluminum and runs Apple’s S10 chip with an always-on display. It keeps the essentials: heart rate notifications, irregular rhythm notifications, sleep score and sleep apnea notifications.
What you give up is the ECG app, the Blood Oxygen app and the readiness score, and battery is shorter at up to 18 hours, or 32 hours in Low Power Mode. A 15-minute charge adds up to 8 hours.
What it does well
- From $249, $150 less than the Series 12.
- Sleep score and sleep apnea notifications.
- Always-on display.
What to know before buying

It has a 1.32-inch display in a stainless steel case, more than 160 workout modes, free offline maps with turn-by-turn directions and Zepp Flow voice control. Running metrics include VO2 Max, heart rate zones and recovery time.
What it does well
- $99.99 with up to 10 days of battery.
- Offline maps with turn-by-turn directions.
- Works with iPhone and Android.
What to know before buying
- Battery drops to 5 days with heavy use.
- A smaller app selection than Apple and Wear OS watches.
Best Smartwatch for Android: Galaxy Watch9 or Pixel Watch 5
Both run Wear OS, both start around $380 to $400, and both work best with a phone from the same brand. The differences come down to three things:
- Battery: Google rates the Pixel Watch 5 at up to 30 or 40 hours by size; Samsung lists battery capacity, 390 or 445 mAh, rather than hours.
- Health tools: Samsung has the Heart Health Score, Bedtime Guidance and an FDA-cleared sleep apnea feature; Google has Loss of Pulse Detection.
- Price: the Watch9 starts at $379.99 and the Pixel Watch 5 at $399.
If you own a Galaxy phone, the Watch9 unlocks the most features. With any other Android phone, the Pixel Watch 5 is the safer pick.
Smartwatch Battery Life: From 18 Hours to 12 Days
Battery life varies more than any other spec on this list:
- About a day: Apple Watch SE 3 (up to 18 hours) and Series 12 (up to 24 hours).
- One to two days: Pixel Watch 5 (up to 30 or 40 hours) and Apple Watch Ultra 4 (up to 50 hours).
- A week or more: Amazfit Active 2 (up to 10 days) and Garmin Venu 4 (up to 12 days).
Fast charging narrows the gap for the daily-charge watches: 15 minutes adds up to 8 hours on the SE 3, 12 hours on the Series 12 and 18 hours on the Ultra 4, enough to top up while you shower.
What Smartwatch Health Sensors Measure
Every watch here tracks heart rate and sleep, but the extra sensors differ:
- ECG: the Series 12 and Ultra 4 can take a single-lead ECG; the SE 3 cannot.
- Heart rate variability: a measure of the variation between heartbeats, used as a stress and recovery signal; the Series 12 now samples it up to 24 times more often, and the Garmin and Amazfit track it too.
- Sleep apnea: Apple’s watches send sleep apnea notifications, and Samsung’s Watch9 has an FDA-cleared sleep apnea feature.
- Readiness scores: Apple’s readiness score, Samsung’s Energy Score and Garmin’s Health status all turn overnight data into a daily read on how hard to push.
None of these replace a doctor’s diagnosis; they are early-warning and trend tools. If you are still choosing between platforms, our list of Apple Watch alternatives covers more watches that work with an iPhone.
How to Choose a Smartwatch
Four questions get you to the right watch:
