Quick verdict for the time-pressed

There is no single "best" smartwatch – but there is a best smartwatch for you. We compare five currently relevant models that serve different priorities: maximum ecosystem integration, the longest battery life, or the best value for money.

  • iPhone users: practically can't get past the Apple Watch Series 11 – Apple does not allow full pairing with Android
  • Android users have two mature but differently focused Wear OS options in the Samsung Galaxy Watch9 and Google Pixel Watch 4
  • Maximum battery life: the Amazfit Balance 2 (up to 21 days) and Garmin Venu 4 clearly outlast classic OLED smartwatches
  • All market prices on this page were verified via live retrieval from Amazon.de on 24 August 2026

What really matters when buying a smartwatch

Before you decide on a model, it's worth looking at four key criteria: operating system compatibility with your smartphone, everyday battery life, the actual scope of the health features, and the price segment. We explain all four points in detail in our buying guide.

In short Your smartphone ecosystem usually decides first: iPhone means Apple Watch, Android lets you choose between Samsung, Google, Garmin and Amazfit. Only after that is it worth looking at battery life, health features and price.

FAQ on the smartwatch comparison

There is no single "best" winner, because the right choice depends heavily on your smartphone and how you use it. iPhone users are practically limited to the Apple Watch Series 11 (Apple does not allow full pairing with Android). Android users have two mature Wear OS options in the Samsung Galaxy Watch9 and the Google Pixel Watch 4. Anyone looking for maximum battery life and sport features at a lower price is better served by the Amazfit Balance 2 or the Garmin Venu 4.
No. The Apple Watch requires a paired iPhone to be set up and to use its full range of features. Conversely, Samsung Galaxy Watch, Google Pixel Watch, Garmin and Amazfit models work with the vast majority of current Android smartphones, and some even offer limited support with iPhones (e.g. Garmin and Amazfit via their respective apps).
In this comparison, the Amazfit Balance 2 offers by far the longest runtime, with up to 21 days in typical mode according to the manufacturer, followed by the Garmin Venu 4. The Apple Watch Series 11, Samsung Galaxy Watch9 and Google Pixel Watch 4 are classic always-on OLED smartwatches designed for 1-2 days of runtime per charge, but offer a larger app ecosystem in return.
The Apple Watch Series 11, Samsung Galaxy Watch9 and Google Pixel Watch 4 all feature an ECG function. The Amazfit Balance 2, on the other hand, does not offer ECG, but does have a very long battery life and a considerably lower price. Important: ECG features are available to varying degrees depending on country and regulatory approval and do not replace medical diagnostics.
Market prices were determined via direct live retrieval of the respective Amazon.de product pages (as of 24 August 2026) and are labelled accordingly. Since Amazon prices can change several times a day, we recommend checking the current price via the buttons on this page before purchasing.

Our verdict

The five models compared here serve different priorities: the Apple Watch Series 11 remains practically unrivalled for iPhone users and impresses with mature health features. On Android, the Samsung Galaxy Watch9 leads on the overall package, while the Google Pixel Watch 4 offers a unique safety feature with Satellite SOS and Gemini AI. Anyone prioritising long battery life and sport features is well served by the Garmin Venu 4 or the especially affordable Amazfit Balance 2.
