The Best Smartwatches Right Now

Sixty hours with the always-on display running is the longest published figure among the full smartwatches here, and it survives a two-night trip without the charging puck. Titanium case, IP69K and 10 ATM, plus EN13319 certification for diving. Hold the quick button for five seconds and an 86-decibel siren fires, quoted as carrying up to 180 meters. Gate: it wants an Android 13.0 phone with 1.5 GB of memory.

Forty-two hours of normal use and seventy-two in Low Power Mode, which is the difference between charging every night and packing no charger at all for a weekend. Rated WR100 and described as fit for recreational scuba to 40 meters, with IP6X dust resistance and a display quoted at up to 3000 nits for sun. Emergency SOS and Messages both run over satellite. Gate: iPhone only, and enormous on a small wrist.

Thirty hours on the 41 mm case and up to forty on the 45 mm, so picking a size is really picking a battery if you sleep-track. Google says Loss of Pulse Detection can detect a loss of pulse event and prompt a call to emergency services; the page carries no clearance wording, so read that as what the maker claims rather than a diagnosis. Gate: Android 11.0 or newer.

Android's most complete answer, and it climbs above better-batteried rivals on one point: Samsung states that its sleep apnea feature is regulated by the U.S. FDA as a medical device, one of only two regulatory claims in this list. Readings come off the BioActive sensor. Cells are 390 mAh at 40 mm and 445 mAh at 44 mm, with no hours figure published. Gate: Android 13 plus Samsung Health.

Sleep in it, shower in it, charge it while you brush your teeth: 24 hours of battery life makes that routine non-negotiable, and it is why this sits below the bigger cases. Sensor breadth buys some of it back. The ECG app records a single-lead electrocardiogram to check for signs of atrial fibrillation, alongside notifications for possible hypertension and possible sleep apnea. Gate: iPhone 11 or later.

Cheapest way onto watchOS, and last among the full smartwatches purely on endurance at eighteen hours of normal use. A 15-minute fast charge buys eight hours back, which rescues a forgotten night. Sensors cover high and low heart rate notifications, irregular rhythm notifications and wrist temperature, and sleep apnea notifications are listed for it. Always-On Retina display behind Ion-X glass. Read the comparison chart before assuming parity with Series 11.

Runners keep coming back to this for a boring reason: 32 grams with the nylon band, light enough to vanish on a wrist by mile eight. COROS quotes 19 days of daily training and sleep tracking per charge and 41 hours with GPS running, a different universe from the mainstream watches above. The 1.2-inch AMOLED display stays legible at midday. Smart features are thin, and that is the trade.

Off-grid messaging without a second gadget in the pack, because inReach satellite messaging is built into the case, though Garmin says plainly that an active subscription is required for it, which costs a place here. Its ECG app records something similar to a Lead I ECG and looks for atrial fibrillation or normal sinus rhythm. Garmin attaches its 27-day estimate to the 51 mm model, not to this one.

Plastic, chunky, monochrome, and the one here you stop thinking about entirely. Solar charging tops it up through daylight, and the case is built to MIL-STD 810 for thermal and shock resistance. Its built-in flashlight offers variable intensities, a red light and a strobe mode, which reads like a gimmick until the first 6am dog walk in November. No smartwatch-mode figure is published for this size.

Hands, a proper dial, and a small screen consulted only when you want it. That hybrid dial with embedded PMOLED screen is why this survives on a wrist that hates gadgets, and up to 35 days between charges is the longest run in the list by a distance. Withings states that its ECG functionality has been cleared by the FDA. Works with iOS and Android, and does far less than the watches above.

Screen-free and subscription-free, a rarer pairing than it ought to be: the maker's page promises full access to every feature from day one, no monthly fees, pay once. Up to 8 days on a single charge backed by 4 weeks of onboard memory, so a fortnight of forgetting to sync costs you nothing. Not a watch at all, which is what keeps it down here rather than lower still.

Band-shaped rather than watch-shaped, which matters if a slab on the wrist is why you gave up last time. Seven-day battery life, and it pairs with most phones running Android 11 or iOS 16.4 or newer, so it does not care which side of the fence you live on. The compatible ECG app assesses heart rhythm for atrial fibrillation. Google's own pages disagree over which scores need a paid membership.

No screen, no notifications, and by the end of week one you forget it is on your finger. One charge lasts six to nine days depending on ring size and usage, and the titanium exterior takes door handles and dumbbells better than expected. Sleep and recovery are what it does honestly well. It's last because Oura sells a membership alongside the hardware, so the thing you bought keeps asking.
