Samsung S25 Ultra Teardown Reveals Slow Progress
An iFixit teardown of the Galaxy S25 Ultra shows some improvement in repairability, particularly a faster battery replacement process. However, the report notes "slow progress" overall, with persistent adhesives and complex assemblies limiting serviceability—a continued challenge for highly integrated device designs.
Samsung's continued use of strong adhesive on the rear glass panel remains a primary obstacle to initial device entry, necessitating heat and prying tools which complicates what should be a routine access procedure. Once inside, a familiar array of 18 Phillips screws must be removed before the main internal components, including the motherboard and battery, can be accessed. The S25 Ultra's easier battery replacement is facilitated by redesigned pull tabs, a purely mechanical solution. This approach differs from Apple's recent strategy in some models which employs an electrically debonding adhesive, requiring a specific electrical current to release the battery from the chassis. A key internal upgrade is a significantly larger copper vapor chamber compared to the S24 Ultra, a necessary thermal management solution for the Snapdragon 8 Elite for Galaxy chipset. The main logic board is also smaller,
