Galaxy S25 Ultra’s Superfast Charging 2.0 not so super, users report bugs: Samsung plans new One UI 7 update

Samsung has acknowledged bugs in Galaxy S25 Plus and Ultra’s Superfast Charging. It appears to be a widespread problem as the social platforms and Samsung’s Community forums have exploded with similar complaints.
Recently, Samsung Italia acknowledged bugs in Superfast Charging on the Galaxy S25 Plus and S25 Ultra. The vanilla model remains excluded as it doesn’t support 45W superfast charging functionality and is capped at 25W.
The official release has started on February 7 and consumers are gradually receiving their new Galaxy devices. Several owners reported on X, Reddit, and Samsung Community that the new S25 +/Ultra doesn’t properly support 45W charging.
The reason is suspected to be a lack of support for the 5A cable. Samsung’s Italia subsidiary asked a user, while pledging a fix with future One UI 7 update, whether they are using a 5A cable instead of the 3A cable that arrived in the box.
Galaxy S25 Plus and Ultra feature a new charging profile. The company has made hardware-level tweaks to end the necessity of a 5A cable for Superfast charging. The in-box cable of 3A is also capable of charging the phone at 45W.
Samsung fans having a 5A cable and 45W brick may have been charging their S25+ or Ultra with the same products. The shift in the charging profile was probably overseen by the software team resulting in bugs in the Superfast Charging.
It’s worth noting that the lock screen shows Superfast Charging 2.0 but the real experience isn’t the same. The flagship models allegedly take hours to recharge the battery with the same adapter and cable used to charge existing Galaxy devices.

Samsung, NVIDIA plot next-gen SOCAMM memory for AI authority

Nvidia is reportedly in talks with Samsung and SK Hynix for a SOCAMM AI chip. The company is accelerating its collaboration with Korean chip makers amid the AI boom.
According to BusinessKorea, Nvidia is pushing Samsung and SK Hynix for commercialization of SOCAMM (System on Chip Advanced Memory Module) AI memory technology.
A report from another trusted outlet suggests that Nvidia, Samsung, and SK Hynix are exchanging SOCAMM prototypes for testing, with mass production expected to start by the end of 2025.
SOCAMM uses low-power LPDDR5X for better efficiency and performance. It can dramatically boost data transfer speeds, which would be crucial for AI computing with extra I/O pins.
SOCAMM’s detachable module design is the biggest strength that lets users easily replace the memory. NVIDIA’s push for its memory standard marks a major shift from the JEDEC framework.
Earlier this year, the US chip giant introduced GB10 Grace Blackwell Superchip and Project DIGITS. SOCAMM could be the next-gen HBM with superior performance and power efficiency.
An industry source noted:
“Memory standards have traditionally been determined by a consensus among multiple PC, memory, and server companies at JEDEC, but NVIDIA is pursuing its own memory standard, reflecting confidence in its innovation and influence.”
