Samsung’s Galaxy Watch9 brings a new 3nm chip, a brighter sapphire screen and a battery about 20% larger than the last generation. The two detailed reviews published so far agree on one thing, though: in practice it is still a watch you charge every day, and the charging itself is slow.
This is a documented review: I brought together Samsung’s official specs and the measured results published by GSMArena and Android Central, then added my own verdict.
At a glance
| Item | Details |
|---|---|
| Price | From USD 379.99; Android Central lists USD 379.99 to 429.99 depending on model |
| Arab market availability | Officially sold by Samsung Gulf through its UAE online store; no official AED price was readable on Samsung’s page |
| TechKahwa rating | 7.3/10 |
| Best for | Samsung phone owners who want a fast, bright, comfortable Wear OS watch |
| Skip if | You want multi-day battery life or quick top-ups |
Samsung announced the Watch9 at Galaxy Unpacked on July 22, opened pre-orders the same day in select markets, and put it on sale on August 7.
Design and display
The Watch9 comes in 40mm and 44mm sizes. According to Samsung’s newsroom, the 44mm model has a 1.47-inch 480 x 480 screen and the 40mm model a 1.34-inch 438 x 438 screen, both under sapphire crystal and rated up to 3,000 nits. Durability covers 5ATM, IP68 and MIL-STD-810H.
It is a light watch. GSMArena lists 32 g for the 40mm model and 34 g for the 44mm, and Android Central says its 44mm unit weighs just over 34 g. One note for anyone reading Samsung’s own material: the “14 g” figure you may see refers to the band, not the watch.
What caught my attention is how much of this generation’s change is invisible. From the outside, the Watch9 looks familiar. The real work happened inside.
Performance and battery
The new chip is Qualcomm’s SDW6100, branded Snapdragon Wear Elite: a penta-core, 3nm part paired with 2GB of RAM and 32GB of storage. It runs Wear OS 7 with One UI 9 Watch. Reviewers describe the chip as much faster than the one in the previous generation.
Battery capacity rises to 445mAh on the 44mm model and 390mAh on the 40mm model, about 20% more than before. Unfortunately, the measured results do not show a matching gain:
- GSMArena’s 40mm unit lasted “a little over 24 hours” in a day that included a 3-hour GPS hike, and “less than 24 hours” with the always-on display and 1.5 hours of workouts.
- Android Central says the battery “barely lasts through the day”.
Charging is the other weak point. GSMArena measured “about an hour and a half” from dead to 100%, and Android Central says charging “takes well over an hour”. For a watch you need to top up daily, that makes timing matter: you have to plan a charging window rather than grab a quick boost.
| Test | Result | Reviewer |
|---|---|---|
| Day with a 3-hour GPS hike (40mm) | A little over 24 hours | GSMArena |
| Always-on display and 1.5 h of workouts (40mm) | Less than 24 hours | GSMArena |
| Everyday use | Barely lasts through the day | Android Central |
| Full charge from empty | About 1.5 hours | GSMArena |
| Full charge | Well over an hour | Android Central |
What reviewers agree on
Strengths:
- A much faster chip than the previous generation
- A very bright sapphire-covered display
- A light, comfortable design
- A full set of health tracking on a Samsung phone
Weaknesses:
- Battery life is still about one day despite a 20% larger battery
- Slow charging, about 90 minutes to full in GSMArena’s test
- The design looks largely unchanged
- Fewer features when paired with a non-Samsung phone
Who should buy it
If you use a Galaxy phone and your current watch is two or three generations old, the Watch9 is a sensible upgrade. You get a faster, smoother watch with a very bright screen, a light build and deep integration with your phone.
If you own a Watch8, I would skip this year. The speed gain is real, but the daily charging routine stays the same, and the charge itself takes a long time. The same goes for anyone who needs a watch to last a weekend away without a charger.
In the Arab market, Samsung Gulf sells the Watch9 officially through its UAE online store. I could not read an official AED price on Samsung’s page, so check the store directly and compare it with authorized retailers before you buy.
Verdict
The Galaxy Watch9 is a faster and brighter watch that still lives on a one-day battery. GSMArena’s and Android Central’s findings line up: the extra 20% of capacity has not turned into extra days, and a charge takes around an hour and a half. In my opinion, Samsung solved the performance problem this year and left the battery problem for next time.
My rating is 7.3/10: a good Wear OS watch for Galaxy owners with older models, and an easy pass for Watch8 owners.
