Galaxy S25 Edge Teardown Reveals the Secrets Behind Samsung’s Slimmest Flagship Yet

Highlights

• Teardown video reveals the Galaxy S25 Edge achieved a slim design by removing the USB-C housing and using a thinner vibrator motor.
• The phone features a wide vapour chamber cooling system with the chipset sitting directly on it and a redesigned thinner motherboard.
• The battery was trimmed down to maintain the slim profile, but it includes Samsung’s quick-release system for easier removal.
• The titanium frame doubles as a support structure, saving space.

The Samsung Galaxy S25 Edge launched last month and at just 5.8mm thin, it’s one of the slimmest flagship phones Samsung has ever made. The Korean brand recently shared some engineering details. But if you’ve been curious about what’s going on under the hood of the actual phone, a new teardown video is out. It gives us a closer look at the impressive engineering that made this design possible.

The teardown comes from none other than JerryRigEverything, a YouTuber known for stress-testing and dismantling popular smartphones. After acing his durability and bend tests, the Galaxy S25 Edge now goes under the knife of JerryRigEverything.

One of the standout discoveries is the super-thin vibrator motor placed just below the fingerprint scanner. It’s noticeably slimmer than what Samsung typically uses in its flagships.

The teardown also shows how Samsung ditched a separate USB-C housing, instead using the titanium frame itself to guide the charger, a smart move to shave off a bit more bulk.

Opening the phone is fairly straightforward. They apply some heat to loosen the adhesive, then use a suction cup to pull the back panel off. Once inside, you’ll find a ton of screws and clever layout choices made to reduce thickness.

For example, the speaker’s waterproofing membrane is angled due to the tight internal space. The USB-C port is bare with no housing and the titanium frame doubles as a support structure.

The vapour chamber cooling system is another highlight. It’s wide and flat and takes up more space to help manage heat. Interestingly, the chipset sits directly on the vapour chamber with a thick layer of thermal paste in between. This is quite unlike in the Galaxy S25 Ultra, where it sits on a dedicated frame.

The motherboard layout has also been redesigned to be thinner, possibly hinting at what we can expect from slim phones in the future, even from brands like Apple

Removing the battery is incredibly easy too, thanks to the same quick-release system introduced in other S25 models. Unsurprisingly, the battery is one of the areas where Samsung trimmed down to hit the 5.8mm profile.

FAQs

Q1. How did Samsung achieve the ultra-slim design of the Galaxy S25 Edge?

Answer. The Galaxy S25 Edge is just 5.8mm thick, making it Samsung’s slimmest flagship. The company achieved this by removing the USB-C housing, using a thinner vibrator motor, and trimming down the battery, while the titanium frame doubles as a support structure.

Q2. What cooling system does the Galaxy S25 Edge use?

Answer. The phone features a wide vapour chamber cooling system, and unlike the Galaxy S25 Ultra, its chipset sits directly on the vapour chamber with a thick layer of thermal paste in between for improved heat dissipation.

Q3. How easy is it to remove the battery in the Galaxy S25 Edge?

Answer. Samsung included its quick-release battery system, making battery removal easier compared to older flagship designs. However, the battery itself was slimmed down to maintain the 5.8mm profile.
