Apple Watch Series 10 Review: Thinner, Smarter, and Worth Upgrading To

The Thinnest Apple Watch Ever

At 9.7mm, the Apple Watch Series 10 is 10% thinner than the Series 9 and finally feels like a piece of premium jewellery rather than a tech gadget strapped to your wrist. The new titanium case option is featherlight at 36.4 grams, which makes a genuine difference during sleep tracking and workout sessions.

Health Features: The Standout Upgrade

The headline new feature is FDA-cleared sleep apnea detection — a genuinely meaningful health addition that could identify a serious sleep condition in users who'd never suspected they had one. The electrical heart sensor (ECG) and blood oxygen monitoring continue from earlier generations, and the new depth gauge and water temperature sensor make it the most capable water sports watch Apple has shipped.

Battery Life and Charging

The Series 10 officially offers 18 hours of standard use, matching the Series 9. In practice, with always-on display disabled, we consistently hit 22–24 hours. The new faster charger gets you from 0–80% in just 45 minutes — a significant improvement if you're in the habit of charging while you shower.

The Verdict

At $379 — $50 below the launch price — the Apple Watch Series 10 is the best all-round smartwatch you can buy if you have an iPhone. The health features, particularly sleep apnea detection, represent genuine long-term value. For Series 4 users or older, the upgrade is compelling. Series 8 and 9 owners can comfortably wait another generation.

Pros

  • Thinnest Watch design ever — feels great all day
  • Sleep apnea detection is a genuine health tool
  • Faster 45-minute charging cycle
  • Wider display without making the case larger

Cons

  • 18-hour claimed battery doesn't stretch to two days
  • Requires iPhone — no standalone use
  • Significant upgrade only if coming from Series 6 or older

Our Verdict

The Apple Watch Series 10 is Apple's best wearable yet. The combination of a thinner design, sleep apnea detection, and faster charging makes it a compelling health companion.

Frequently Asked Questions

Is the Apple Watch Series 10 worth upgrading from Series 8?
For Series 8 owners, the upgrade is marginal — thinner design and sleep apnea detection are the only meaningful additions. If you don't have sleep concerns, hold off for Series 11. Series 6 owners and below will see significant improvements.
Does the Apple Watch Series 10 work with older iPhones?
The Apple Watch Series 10 requires iPhone XS or later running iOS 17 or later. It works with all iPhone models from 2018 onwards.
