Samsung is reportedly improving the power efficiency of its next-generation Exynos modem, potentially addressing a long-standing battery-life concern with some Galaxy smartphones powered by the company’s own chipsets.
The upcoming M2700 modem, expected to pair with the Exynos 2700 chipset in some Galaxy S27 models, is said to deliver improved power efficiency and performance comparable to or better than competing products, according to industry sources cited by South Korean publication The Elec.
The development could help Samsung narrow the perceived gap between Exynos-powered Galaxy phones and their Snapdragon-powered counterparts, particularly in standby power consumption.
However, Samsung has not officially confirmed the reported specifications or the modem’s performance claims.
M2700 reportedly improves efficiency without a smaller process node
According to the report, the M2700 will be manufactured using Samsung’s 4nm process, the same node reportedly used for the modem in Exynos 2600-powered Galaxy S26 models.
Despite using the same manufacturing process, the new modem is said to improve power efficiency through design changes, including voltage adjustments. An optical die shrink has reportedly reduced the chip’s area by 4%.
Samsung is also reportedly moving away from the Exynos Modem branding in favour of an M-series naming system for its future modems.
If the reported improvements translate into real-world performance, the M2700 could help reduce modem-related battery consumption without requiring a transition to a more advanced manufacturing node.
New modem to support updated 5G and satellite capabilities
The M2700 is also expected to bring connectivity upgrades, moving from 3GPP Release 17 to Release 18, associated with the evolution of 5G Advanced technologies.
The modem is reportedly set to improve Non-Terrestrial Network capabilities, which can support satellite-based communications.
The extent of these improvements, including which features will be available to consumers, remains unclear pending official specifications.
Galaxy S28 modem reportedly planned for 2nm process
Looking further ahead, Samsung is reportedly developing the M2800 modem for Galaxy S28 models, with a move to a 2nm manufacturing process planned.
The transition could further improve power efficiency while freeing up Samsung’s 4nm production capacity for other products, including high-bandwidth memory (HBM) used in AI servers.
Samsung’s System LSI division is reportedly pushing for wider adoption of its own chips across the company’s flagship Galaxy S range. However, whether the Exynos 2700 will power the Galaxy S27 Ultra remains under discussion, according to the report.
