The Samsung Galaxy Watch 9’s biggest upgrade is its processor: Notebookcheck measured benchmark gains of up to 65% over the Galaxy Watch 8. That makes the Watch 9 a compelling choice if speed, a bright display, and broad smartwatch features matter most. It is not a sweeping upgrade, however, and battery life remains a significant weakness. The review found no endurance improvement over the Watch 8, with the tested 44 mm model sometimes appearing slightly worse.

Is the Galaxy Watch 9 worth it?

It depends on what you want from a smartwatch. The Watch 9 combines a substantially faster processor, a bright screen, fitness tracking, and Samsung’s health features in a well-made design. But the performance increase does not make every part of the experience better: Notebookcheck describes the overall generational upgrade as relatively modest, and its battery testing is a notable caveat.

Choose it if you value responsiveness, display visibility, and a wide set of features, and are comfortable charging frequently. If multi-day endurance or access to every health measurement without a Samsung phone is essential, weigh those limitations before buying.

How much faster is the Galaxy Watch 9?

The Watch 9 replaces the Watch 8’s processor with Qualcomm’s Snapdragon Wear Elite SW6100. Notebookcheck reported benchmark gains of up to 65% over the Watch 8. In one example, its Octane V2 results were 21,546 points for the Watch 9 and 13,026 for the Watch 8. The review notes that the watches used different browser versions for that test, so the score is an illustration, not a universal measure of speed.

In daily use, Notebookcheck found the watch smooth overall, though occasional minor delays remained. The faster chip is therefore a meaningful technical improvement, but it should not be taken to mean that every interaction feels dramatically different.

How long does the Galaxy Watch 9 battery last?

Notebookcheck’s 44 mm test did not show better battery life than the Watch 8. With Always-On Display and health features enabled, no eSIM, and no manually started workouts, the watch used about 40% to 50% of its charge between 6 a.m. and 9 p.m. With sleep tracking enabled, consumption was about 60% to 70% over 24 hours. A full recharge from empty took almost 1.5 hours.

These are results from the review’s particular settings and test routine, not a guaranteed runtime. Screen settings, cellular use, workouts, and other features can affect consumption.

The tested 44 mm model has a 445 mAh battery, just 10 mAh larger than the Watch 8’s. The review says the 40 mm variant receives the advertised 20% increase in battery capacity, but that does not establish how long it lasts in use.

What is new in the Galaxy Watch 9 compared with the Watch 8?

The processor is the central change. Other strengths include a bright display and the same broad mix of smartwatch, fitness, and health functions, but the review does not characterize the Watch 9 as a wholesale redesign.

Feature Galaxy Watch 9, 44 mm review unit What the review establishes about the Watch 8
Processor Qualcomm Snapdragon Wear Elite SW6100 The Watch 9 replaces the Watch 8’s processor; Notebookcheck measured benchmark gains of up to 65%.
Display 1.50-inch, 480 × 480 Super AMOLED with sapphire crystal Not stated in the review findings summarized here.
Battery capacity 445 mAh The Watch 9’s 44 mm battery is 10 mAh larger.
Battery life No improvement in Notebookcheck’s 44 mm test; it appeared slightly worse in the tested software configuration. The review uses the Watch 8 as the battery comparison but does not provide a separate runtime figure here.
Overall change Faster processor, but a relatively modest overall generational upgrade according to the reviewer. Predecessor used as the comparison model.

Specifications and measurements in this table describe Notebookcheck’s review, not a complete independent comparison of every configuration.

Is the Galaxy Watch 9 display bright enough outdoors?

Notebookcheck measured a peak of 3,162 cd/m² on the 44 mm watch with its ambient-light sensor enabled, and 591 cd/m² without that sensor condition. The review cautions that results vary with screen settings. Treat the higher figure as a measured peak under the specified condition, not the brightness you should expect at all times.

Should you get the 40 mm or 44 mm Galaxy Watch 9?

The review’s detailed test was of the 44 mm model, so its screen, battery-use, and charging observations apply to that unit. The 44 mm has a 1.5-inch display and a 445 mAh battery. The review identifies a 20% battery-capacity increase for the 40 mm version, but does not supply equivalent measured runtime results for it.

For the choice between sizes, consider how the case and display fit your wrist and whether you prefer a smaller watch or the tested model’s larger screen. Do not assume the 40 mm will last a particular number of hours based only on its capacity increase.

Which health features work without a Samsung phone?

The watch records heart rate, sleep duration and stages, blood oxygen, skin temperature, respiratory rate during sleep, and workouts through Samsung Health. According to Notebookcheck, ECG and blood-pressure measurement require a Samsung smartphone and the Samsung Health Monitor app; the review also describes sleep-apnea monitoring as a Samsung-phone feature. Without the required Samsung phone and app, those measurements are unavailable.

Blood-pressure estimates also require calibration using a cuff-based monitor at least once every four weeks, as stated in the review. Phone, country, carrier, and software version may affect feature availability, so check current Samsung support information for your region and device before relying on a specific function.

Notebookcheck compared selected readings with reference devices in its own test. It reported average deviations of 1.1% for systolic and 0.4% for diastolic blood pressure, 0.7% for blood oxygen across three measurements, and 4.3 beats per minute (1.5%) for exercise heart rate during a bike ride; resting heart-rate readings were identical. These small review tests are not clinical validation and cannot guarantee accuracy for an individual.

How well does the Galaxy Watch 9 track workouts and routes?

Notebookcheck reports support for more than 100 tracked workouts, automatic recognition of core activities, and dual-band GPS. Its Fitness Index draws on heart rate, VO₂max, and daily steps. In the reviewer’s bike-ride comparison with a Garmin Venu 2, route recording was described as generally accurate. That is a single review comparison, not a promise of identical GPS performance in every setting.

What is the Galaxy Watch 9 like to wear?

The watch has a round brushed-aluminum case, a touch-sensitive display edge rather than a physical rotating bezel, two side buttons, and a speaker and microphone. Its straps are removable and use Samsung’s fastening system. Notebookcheck describes the watch as light and well made; the tested 44 mm model weighs 34 g.

The review lists 5 ATM, IP68, and MIL-STD-810H ratings and considers showering and swimming suitable. It generally advises against scuba diving and jumping from a 10-meter platform. Ratings and use guidance have limits, so do not treat them as protection against every kind of water exposure or impact.

What else should you check before buying?

Notebookcheck’s 44 mm configuration lists Wear OS 7 with One UI 9.0, 2 GB of memory, 32 GB of storage, Bluetooth 6.0, GPS, wireless charging, and a 1.50-inch 480 × 480 Super AMOLED display with sapphire crystal. The LTE version can make calls without a paired phone after eSIM setup. The watch supports Bixby, Google Assistant, and Amazon Alexa. Availability and behavior can vary by country, carrier, phone, and software version.

How does the Galaxy Watch 9 compare with alternatives?

Notebookcheck’s review comparison includes the Huawei Watch GT 7, Apple Watch Series 11, Galaxy Watch 8, and Xiaomi Watch S5, but it does not establish a universal winner. Compare watches against the needs that matter most to you:

  • Phone ecosystem: Check whether the health functions you want work with your phone.
  • Battery and charging: Consider sleep tracking, cellular use, and how often you are willing to recharge.
  • Performance and display: Compare everyday responsiveness, screen size, measured brightness, and case size.
  • Fitness and navigation: Look at workout coverage and route tracking for your activities.
  • Local buying details: Confirm current price, cellular availability, and carrier support in your region.
