According to prolific tipster @UniverseIce, the upcoming Samsung Galaxy S25 Ultra could receive a significant memory upgrade, potentially offering up to 16GB of RAM. If this tip holds true, it would mark a substantial improvement over its predecessor, the S24 Ultra, which currently ships with a maximum of 12GB of memory.
Another tipster, @theonecid, seems to corroborate this information. They suggest that the Galaxy S25 and Galaxy S25 Plus will come with up to 12GB of RAM, while the top-tier Galaxy S25 Ultra could boast up to 16GB of RAM2. Although neither post explicitly specifies the top-end models, it’s likely that the base S25 Ultra will still offer 12GB of memory, while the vanilla S25 and S25 Plus may have variants with 8GB RAM.
This potential RAM upgrade aligns with earlier reports that the Galaxy S25 lineup will feature LPDDR6 RAM, a step up from the DDR5 memory found in the Galaxy S24-series devices1. However, keep in mind that these details are still unverified rumors, pending official confirmation from Samsung. As always, take them with a pinch of salt until further announcements are made.
