Difference between Apple Watch 8 and 9: which choice will save you the most money?

Apple Watch 8 or 9: The honest story

You're not alone in this question. Thousands of buyers are grappling with the same dilemma. The 9 is newer, so it's better. The 8 is cheaper, so it's smarter. Yet, the difference between the two models is smaller than Apple would have you believe .

The real secret? You'll probably never use most of the Watch 9's new features. That brighter screen? Only noticeable in direct sunlight. That faster processor? It shaves half a second off the time it takes to open apps. And yet you 're paying hundreds of euros extra for technology that sounds impressive on paper.

Just like with AirPods and other Apple accessories, it's all about what you need, not what Apple promotes. That's why we explain the differences without the sales pitch.

Useful links

The processor makes the difference (or does it?)

The S9 chip in the newer model sounds impressive. In practice, you'll especially notice the difference when opening demanding apps like maps or workout tracking. For reading messages, making calls, or controlling music, it's a fraction of a second difference at most. The Apple Watch 8 with its S8 chip does exactly the same job, just a bit slower.

What many users don't realize is that both chips share the same architecture. The difference lies primarily in power management and speed, not in features. All apps that run on the 9 also work perfectly on its predecessor.

The Screen: Brighter Doesn't Always Mean Better

Apple touts the 2000-nit display brightness of the Series 9. The Series 8 achieves 1000 nits. Sounds like a world of difference, but when do you need that extra brightness? Only on sunny days outside. At home, in the office, or in the evening while exercising, you won't notice any difference.

Both screens have the same resolution, the same always-on function, and the same scratch-resistant coating. However, the brighter display consumes more power when used at maximum brightness. This can impact battery life on sunny days.

Practical differences in daily use

  • Indoors: no visible difference between the two models
  • Cloudy outside: minimal difference, both perfectly readable
  • Bright sun: Series 9 clearly more readable
  • Battery consumption: Series 9 consumes more at maximum brightness

Health measurements: marginal improvements

The sensors for heart rate, oxygen measurement, and temperature are virtually identical. The newer model has a slightly more accurate temperature sensor, but the difference is negligible. Neither watch is suitable for medical use; they serve only as an indication.

Sleep tracking works exactly the same on both models. You get the same graphs, the same insights, and the same tips. Fall and crash detection also work identically. For athletes, both watches use the same GPS technology and motion sensors.

Battery life: the reality behind the promises

Apple promises 18 hours of battery life for both models. In practice, active users barely get that, while those who primarily receive notifications easily get two days. The difference between 8 and 9? At most, a few percent with normal use.

Charging speeds do differ. The latest model charges about 15% faster. Convenient if you need to get out the door quickly, but not a game-changer. Both watches charge from 0 to 80% in about 45 minutes.

Tips for longer battery life

  • Turn off always-on display when not needed
  • Limit background app refresh
  • Don't use animated watch faces
  • Turn off automatic workout detection

New features you probably don't use

The Series 9 introduces the double-tap feature, which allows you to tap with your thumb and index finger to perform actions. It sounds convenient, but it works poorly. Most users forget this feature exists after a week.

Also new are some exclusive watch faces. Fun for the first few days, but you'll eventually go back to your trusted favorite. The on-device Siri is a real improvement; voice commands work without an internet connection. Handy when running in areas with poor coverage.

Price and availability: this is where you really win

The Apple Watch 8 has dropped significantly in price. You can easily save €100 to €150 compared to the latest model. For that money, you could buy an extra strap, a wireless charger, or save it for your next iPhone.

Refurbished Series 8 models are even more affordable. These devices have been fully inspected, receive a new battery if necessary, and come with a warranty. The price difference can be up to €200 or more.

When do you choose which model?

The Apple Watch 8 is perfect when you:

  • A reliable watch without any fuss
  • Exercise mainly indoors or in the shade
  • Would like to save money for other purchases
  • Not interested in the latest bells and whistles

The Apple Watch 9 is a better fit for you if you:

  • Always want the latest
  • Lots of outdoor sports in the sun
  • Values ​​faster performance
  • The on-device Siri function is important

Don't forget the straps

Both models use the same straps. Your entire collection will fit on both the 8 and the 9, provided you stick with the same case size (41mm or 45mm). This means you don't have to buy new straps when switching. An often-overlooked advantage that can save you hundreds of euros.

Note that some new Apple bands are only available in certain colors for the latest model. Functionally, this doesn't make a difference; it's purely about exclusivity.

The real question: what do you need?

Both watches do what they're supposed to: show notifications, track activity, monitor health, and be useful during workouts. The difference lies in the details that are barely noticeable to most users.

Also consider alternatives like the Apple Watch SE. It offers 80% of the features for 60% of the price. Or check out older models like the Series 7, which are often available at bargain prices. The differences between generations are shrinking, while the price differences are increasing.

The smart choice

The difference between the Apple Watch 8 and 9 is smaller than the price suggests . For most users, the Series 8 offers everything you need: reliable health tracking, excellent battery life, and a bright screen.

Those extra hundreds of euros for the 9? Invest them in a refurbished model with a warranty , or save the money for your next phone. Because let's face it: in two years, that lightning-fast processor today will be outdated, while your wallet will still be happy with the smart choice you've made now.
