The best smartwatches in 2026

A smartwatch lives on your wrist every waking hour, so the right one isn't about the longest spec list — it's the one you'll actually keep wearing. The biggest factor is which phone you carry: the best watch for an iPhone is rarely the best watch for an Android, so we've picked for both.

The Apple Watch Series 12 is the best for iPhone owners. On Android, the Samsung Galaxy Watch 9 takes that spot. If you're tired of nightly charging, the OnePlus Watch 4 goes for days; serious about training, head to the Garmin.

How we picked

We weigh four things: how useful the watch is day to day (notifications, payments, responsiveness), how accurate its fitness and heart-rate tracking is, real battery life rather than the claim on the box, and comfort across a full day and a night of sleep tracking. Ecosystem matters too — a watch is only as good as the phone it pairs with, so match your pick to your phone first.

Best overall (for iPhone)

1Best overall — our top pick

Apple Watch Series 12

Best for: iPhone owners

For anyone on an iPhone, the Series 12 is the most complete smartwatch you can buy: a bright, responsive display, dependable notifications, broad health sensing, and a huge app library. A readiness-style score is included without a subscription, and battery comfortably lasts the day. The one catch is the obvious one — it only works with an iPhone.

Strengths

• Fast, polished software
• Broad, accurate health sensing
• Best-in-class app ecosystem

Worth noting

• iPhone only
• About a day between charges

2Best for Android phones

Samsung Galaxy Watch 9

Best for: Android owners, especially Samsung phones

The Galaxy Watch 9 is the natural Apple Watch equivalent for the Android world: slick Wear OS software, a polished rotating-bezel interface, strong health tracking, and the tightest integration with Samsung phones. It's the all-rounder most Android users should start with, with the usual Wear OS caveat of roughly a day of battery.

Strengths

• Best Android integration
• Comprehensive health suite
• Smooth Wear OS experience

Worth noting

• Best features favour Samsung phones
• About a day of battery

OnePlus Watch 4

Best for: Android users who hate charging

The OnePlus Watch 4 is the rare full Wear OS watch that lasts days, not hours — around five in its smart mode, easily the standout for battery among watches with a proper app platform. A titanium case and sapphire glass make it feel premium. The trade-offs are size and weight: it's a big watch. But if nightly charging is your dealbreaker, this is the one.

Strengths

• Multi-day battery on Wear OS
• Premium titanium + sapphire build
• Bright, high-res display

Worth noting

• Large and heavy
• Android only

Best for fitness

4Best for serious training

Garmin Forerunner 570

Best for: runners and data-driven training

For training, Garmin goes deepest, and the Forerunner 570 is the current sweet spot: a bright AMOLED display, accurate multi-band GPS, and a full suite of recovery and training-load metrics without a subscription. It's more of a coach you wear than an everyday smartwatch — exactly what runners want — with about a week and a half of battery. On a budget? The older Garmin Forerunner 265 covers most of the same training essentials for noticeably less, if you can find it.

Strengths

• Deep, trustworthy training data
• Accurate multi-band GPS
• Up to ~10–11 days battery

Worth noting

• No ECG sensor
• Fewer smart/app features

Key specs

DisplayAMOLED (1.2" / 1.4")

Amazfit Active 3

Best for: a first smartwatch on a budget

The Amazfit Active 3 delivers a genuinely surprising amount for entry-level money: a sharp AMOLED display, solid health and sleep tracking, built-in GPS, and multi-day battery. It works with both iPhone and Android. The app isn't as refined as the big names and advanced features are fewer, but as a first smartwatch it's hard to argue with the price.

Strengths

• Excellent price for the features
• Multi-day battery life
• Works with iPhone and Android

Worth noting

• App less polished than rivals
• Fewer advanced features

Key specs

Display1.32" AMOLED

The verdict

Match the watch to your phone and the choice gets easy. On an iPhone, the Apple Watch Series 12 is the most complete option; on Android, the Samsung Galaxy Watch 9 is its equal. Prize battery over polish and the OnePlus Watch 4 is the one; train seriously and the Garmin Forerunner 570 earns its place; want to spend the least, the Amazfit Active 3 punches well above its price.
