Exploring the Galaxy S26 Ultra's internals: Improved cooling and a groundbreaking battery removal mechanism earn it a 9/10 rating.
A teardown video of the Galaxy S26 Ultra reveals a thermal paste-based cooling system directly on the Snapdragon 8 Elite Gen 5 chip and a pull-out pouch design that makes battery replacement extremely easy.
The Samsung Galaxy S26 Ultra has just received a near-perfect repairability rating thanks to significant changes in its internal component structure. The latest teardown video from PBKreviews shows the device scoring 9/10 for repairability, demonstrating the company's efforts to optimize temperature and simplify the component replacement process.
The cooling system has been comprehensively upgraded.
The first noticeable change lies in the cooling system. Immediately after removing the back cover, a large graphite film is discovered directly covering the wireless charging coil to aid heat dissipation. However, the real improvement lies deep inside the motherboard.
For the first time, Samsung has added thermal paste to the space between the back of the motherboard and the chassis. Notably, this paste is applied directly to the storage and RAM chip cluster located above the Snapdragon 8 Elite Gen 5 processor. This structure not only helps control temperature more effectively but also confirms that this is the most powerful Qualcomm chip variant currently available.
Innovative pull-out battery removal mechanism.
The biggest highlight in the Galaxy S26 Ultra's internal design is the battery compartment. Instead of using traditional pull tabs, which are often difficult to remove, Samsung has encased the battery in a specialized pull-out pouch with clearly marked edges.
This design makes removing the 5,000mAh battery from the frame incredibly easy, requiring no chemicals or excessive force. This is considered a sustainable design standard that helps extend the device's lifespan through easier battery replacement.
Impressive specifications
Besides its flexible repairability, the Galaxy S26 Ultra maintains its position as a top-tier flagship model with superior hardware specifications:
| Parameter | Configuration details |
|---|---|
| Microprocessors | Snapdragon 8 Elite Gen 5 (3nm) |
| RAM | 12GB |
| Screen | 6.9 inch Dynamic AMOLED 2X, 2K, 120Hz, 2600 nits |
| Main camera | 200MP, 100x optical zoom |
| Batteries and Chargers | 5000 mAh, 60W Fast Charging, 25W Wireless Charging |
| Water resistant | IP68 |
Despite a high score of 9/10, the disassembly process was slightly detracted from due to the overall lengthy time and the meticulousness required for screen replacement. However, Samsung's focus on clever changes such as the pocket-style battery removal mechanism and enhanced thermal paste shows that the company prioritizes the user experience and durability of the device over flashy external features.
