Samsung Galaxy Watch 9 vs. Galaxy Watch 8: Upgrades that matter

Hands-on with the Samsung Galaxy Watch 9.

Samsung Galaxy Watch 9

New chip ahoy!

The Samsung Galaxy Watch 9 is officially here, and debuts Qualcomm's new Snapdragon chip for wearables. This upgrade alone should unlock features like better battery life, new on-device AI capabilities, and better all-round performance. It also has a larger battery which should fix our biggest gripe with the Watch 8.

Pros

  • Features the Snapdragon Wear Elite chip
  • Larger batteries in both sizes
  • New Galaxy AI features
  • Expanded health monitoring features
  • Same weight and size as the Watch 8

Cons

  • Squircle design might not be for everyone
  • Displays haven't gotten larger
  • Slightly more expensive

Samsung Galaxy Watch 8

Still among the best

The Samsung Galaxy Watch 8 stands out from the crowd thanks to the squircle design. It's incredibly light and slim, delivers accurate fitness tracking data, and has plenty of AI smarts. Battery life is the only weak point which means you need to charge it daily.

Pros

  • Cushion design looks stunning
  • Very slim and light
  • Wear OS 6 with Gemini support
  • Near Garmin-level accuracy for health and GPS tracking

Cons

  • Requires almost daily charging
  • No big price cuts yet
  • Strap feels a bit too thin compared to the body

The Samsung Galaxy Watch 9 is finally here, and naturally, the first question that comes to mind is should you buy the latest model or settle for the older one? On the outside, not much has changed, but Samsung has given the Watch 9 some meaningful upgrades on the inside. A new Qualcomm processor, larger batteries, newer Bluetooth version, and a third color option.

While all that sounds great, remember that it's only been a year for the Galaxy Watch 8 and this is still a perfectly fine smartwatch. When the price cuts do eventually happen, the Watch 8 could be a far better value pick as it's not too different from the Watch 9.

Deciding between the Samsung Galaxy Watch 9 vs. Galaxy Watch 8 can be easy, if you know where your priorities lie.

The Galaxy Watch 9 looks almost identical to the Galaxy Watch 8, and that's not surprising. The Watch 8 got a makeover only a year back, so apart from the new colors and few design details, there isn't any difference. It still comes in two sizes of 40mm and 44mm, with each having Wi-Fi and cellular options.

The Galaxy Watch 8 was pretty slim and light, and the Watch 9 features nearly the exact same dimensions and weight. The same ruggedness has also transferred over, which includes the IP68 rating, 5ATM water protection, and MIL-STD-810H certification.

Not everyone is a fan of the squircle design of the Galaxy Watch 8, but I personally think it looks quirky enough to stand out.

The Galaxy Watch 9 features the same displays as the Watch 8. The 44mm Galaxy Watch 9 has a 1.47-inch Super AMOLED panel with a 480x480 resolution, up to 3,000 nits of peak brightness, and a Sapphire Crystal glass cover. The 40mm version on the other hand has a 1.34-inch display.

The Galaxy Watch 8's display has been excellent when we tested it, and we have no real complaints here. Touch response is great, sunlight legibility is adequate, and colors are rich and vibrant. We're expecting similar performance from the Galaxy Watch 9 too.

The big upgrade in the Samsung Galaxy Watch 9 is the processor. Samsung has used the Exynos W1000 chip for the past two generations of Galaxy watches, and it has finally switched to the Snapdragon Wear Elite platform for wearables. More specifically, it's the SDW6100 chip which consists of five cores and is built on the 3nm process.

Compared to the W5 Gen 2 chip, it's said to deliver up to 5x and 7x performance for the CPU and GPU, respectively. The NPU is rated at 10 TOPS and can handle 2B-parameter AI models, making it well-suited to running Gemini Intelligence or even Gemini Live. The Watch 9 still comes with 2GB of RAM and 32GB of storage, just like the Watch 8.

As for pricing, the Galaxy Watch 8 was already $50 more expensive than its predecessor, starting at $349.99. Samsung has held onto this price till now with only minor discounts on some shopping platforms.

The Galaxy Watch 9 has gotten more expensive by $30, which means it now starts at $379.99 and $409.99 for the 40mm and 44mm variants, respectively. The LTE versions for both sizes costs an additional $30. Earlier rumors did point to a $50 increase in price, so this is some consolation I guess.

Some of the other specs that has changed thanks to the new chip is Bluetooth 6. Dual-band GPS is present as well, just like on the Watch 8. The Galaxy Watch 9 uses the same health tracking sensors as the Watch 8.

Battery capacity has thankfully been upgraded. The one-day battery life of the Watch 8 was our biggest gripe, especially since at least a two-day battery life has become quite common for Wear OS watches. The 44mm Watch 9 has a 445mAh battery, while the 40mm version has a 390mAh capacity. Samsung is touting a 30-hour runtime with AOD (Always-on Display) enabled.

The Samsung Galaxy Watch 8 already introduced a redesigned BioActive sensor for more accurate readings and the tracking of new metrics like Antioxidant Index, Running Coach, Vascular Load, and AGEs Index. The Galaxy Watch 9 can do all of these things, and more.

The Galaxy Watch 8 already does a fantastic job of tracking health and fitness data. In our review of the watch, we found that certain metrics like Energy Score tended to be overestimated at times. For instance, even when the score would be above 80, the watch would still suggest prioritizing rest. I'm hoping the Galaxy Watch 9 addresses these few shortcomings.

Samsung Galaxy Watch 9 vs. Galaxy Watch 8: Which one should you buy?

The Samsung Galaxy Watch 9 doesn't reinvent the squircle by any means, but upgrades to the processor and battery capacity makes it that much better. The new on-device AI features, snappier responses from Gemini, and more usage hours between charges are all nice things to have. The bump in price does hurt but all tech has gotten more expensive, no thanks to the rise in memory costs, so we just have to live with it.

If you're not sold on the new features of the Watch 9 and have a habit of charging your wearables daily anyway, I would confidently recommend getting the Galaxy Watch 8 instead. It's still a fantastic product with a lot of life left in it. It delivers excellent tracking performance, has a beautiful display, is lightweight and comfortable, and has a cellular option. Buy it once the price drops though as it's not worth paying full price right now.

Samsung Galaxy Watch 9

A much-needed upgrade

The Samsung Galaxy Watch 9 changes just a few things, but they are very important things. The new SoC and larger battery should allow you to enjoy the new features for longer, between charges.

Samsung Galaxy Watch 8

Best Galaxy for your wrist

The Galaxy Watch 8 is still the best Samsung smartwatch to buy, even nearly a year later. It doesn't have a multi-day battery life, but it's fantastic in pretty much all other areas.
