Leaks related to the Galaxy S25 series are becoming more frequent as the alleged launch date approaches. We already know some of the key aspects of these devices, although we are still missing pieces to complete the puzzle. In the meantime, an analysis of in-testing Galaxy S25 Ultra files confirms some key details about its hardware, including the storage format implemented, battery, and more.
The Galaxy S25 Ultra will be the most premium model in the lineup, as it has been for years. Leaks about the device have mentioned some interesting improvements, but Samsung will not revolutionize things in 2025 either. You can expect a refined design, more power, better camera quality, and a brighter display. The new Galaxy AI features will probably help round out the experience.
Brighter screen; no support for Find My Device while off
Android Authority has been analyzing Galaxy S25 Ultra files to confirm some key details. There is one negative news, as the device will not offer Find My Device support while it is turned off. The latest Google Pixel 9 series supports this feature, and given the close relationship the two companies have had over the past few years, some were hoping Samsung would integrate the technology into its smartphones. Sadly, it looks like that won’t be the case.
As for the display, the Galaxy S25 Ultra files confirm a 3120 x 1440 px resolution. This is the same resolution as the current Galaxy S24 Ultra, so things are staying the same on that front. However, the source did spot an increase in peak brightness to 3000 nits. For reference, the S24 Ultra can output up to 2600 nits of peak brightness.
In October, tipster Ice Universe revealed that the S25 Ultra’s display will have some notable quality improvements. Plus, Samsung has fixed the grainy effect issue that some S24 Ultra owners complain about.
Galaxy S25 Ultra will remain conservative in battery and storage
Other aspects remain consistent with previous generations. For example, Samsung will keep the same 5,000 mAh battery capacity it has been using for years. The company is notably lagging behind big Chinese brands whose new high-density battery technologies have enabled massive cells without increasing the thickness of phones. The Galaxy S25 Ultra will also implement the same high-speed UFS 4.0 storage format. Lastly, the phone will offer support for seamless A/B updates.
According to leaks, Samsung will hold the first Unpacked event of 2025 on January 22 or 23. In addition to the Galaxy S25 series, the South Korean giant could also tease its Galaxy Ring 2 and smart glasses. In related news, the Ultra variant will be available in a dimmed blue color, according to a trusted tipster.
