The need for a smartwatch is no longer just about style. For many people, smartwatches have become personal assistants on the wrist that are ready to monitor health, track sports activities, and even reply to messages without having to frequently open their phones. Samsung is once again answering that need with its latest generation of smartwatches, the Samsung Galaxy Watch 9.
This watch brings a number of significant improvements over the previous generation. From faster engine performance, sharper AI-based health monitoring, to more optimal wearing comfort. For those of you curious if this watch is worth considering, let's take a look at the in-depth review below!
Iconic and Comfortable Squircle Design on the Wrist
At first glance, Samsung still maintains its signature design language known as squircle. This blend of circle and curved corners gives a futuristic yet elegant impression. The watch body is made from tough Armor Aluminum 2 material, yet remains lightweight on the wrist.
Samsung offers two body size options: 40 mm and 44 mm. The 40 mm variant is perfect for those with smaller wrists or who prefer compact watches, while the 44 mm variant suits those who like a larger display.
One noticeable improvement is the bottom of the watch designed to sit closer to the skin. This allows the health sensors to work much more accurately without causing discomfort or itching on the wrist when worn during sleep. For durability, this watch is equipped with IP68 and 5 ATM water resistance certifications, as well as MIL-STD-810H military standard. So, you don't have to worry about wearing it in the rain or while swimming.
Super AMOLED Display Very Bright Under Harsh Sunlight
The display has always been a key strength of Samsung devices, and the Galaxy Watch 9 is no exception. Using a Super AMOLED panel covered with Sapphire Crystal glass, the screen proves highly resistant to scratches from sharp objects.
The screen size comes in two variations:
- 40 mm variant: Features a 1.34-inch display with 438 x 438 pixels resolution.
- 44 mm variant: Features a 1.47-inch display with 480 x 480 pixels resolution.
The main attraction is the peak brightness level reaching up to 3,000 nits. This ensures the display remains clear, sharp, and vibrant even when you are under direct sunlight at noon. The Always-On Display (AOD) feature also comes with more efficient power consumption than before.
Fast Performance Thanks to Snapdragon Wear Elite Chipset
Internally, Samsung has made a major overhaul to the engine. The Galaxy Watch 9 is powered by the Qualcomm Snapdragon Wear Elite chipset built on a 3-nanometer (3nm) process. This new chipset brings a noticeable leap in energy efficiency and processing speed.
Opening apps, switching interfaces, and processing health data feel very smooth without any lag. Combined with 2 GB of RAM and 32 GB of internal storage, you have plenty of space to store your favorite songs offline or install various apps from the Google Play Store.
It runs the latest generation of Wear OS with the One UI Watch interface. The interface is very intuitive, responsive, and rich in gesture navigation that makes daily use easier.
Health and AI Features: Smarter at Understanding Your Body
The health monitoring features on the Galaxy Watch 9 not only record numerical data but also provide useful contextual suggestions with the support of Samsung Health AI.
Some of the standout health features on this watch include:
- Vitals & Heart Health Score: Regularly monitors vital signs and provides an overall cardiovascular health score. If there is an abnormality in heart rate, the system will immediately give a warning.
- Sleep Quality Analysis & Sleep Apnea: The sleep tracking feature now includes the ability to detect sleep breathing disorders (Sleep Apnea) that has received medical certification.
- Daily Cardio Load: This feature measures your daily physical exercise load and provides suggestions on whether you need rest or can increase exercise volume.
- Hearing Health: This watch can monitor ambient noise levels and give warnings if the sounds around you could potentially damage your hearing.
- Complete BioActive Sensor: You can still perform body composition tests (BIA), ECG tests, blood pressure measurements, and monitor blood oxygen levels (SpO2) independently.
Battery and Charging
Regarding battery life, the 40 mm variant is equipped with a 390 mAh battery, while the 44 mm variant has a 445 mAh battery. Thanks to the energy-efficient 3nm processor, this watch can last up to about 30 hours of active use with the Always-On Display feature on.
For charging, the Galaxy Watch 9 supports fast wireless charging at 10W. You only need a short time to charge in the morning before you're ready to go again.
