Samsung's M2700 Modem Could Make Exynos Galaxy S27 Phones More Efficient

A report says Samsung's M2700 modem for some Exynos 2700-powered Galaxy S27 phones will improve power efficiency, shrink chip area and add newer connectivity capabilities. The claims remain unconfirmed until Samsung announces the hardware.

Samsung's M2700 Modem Could Make Exynos Galaxy S27 Phones More Efficient

Samsung is reportedly preparing a new modem aimed at solving one of the long-running complaints about Exynos-powered Galaxy phones: cellular connectivity can consume more power than expected, particularly when a device is away from Wi-Fi. The report does not establish real-world battery endurance, but it points to a potentially important hardware change for the Galaxy S27 generation.

What the M2700 is reported to change

According to industry sources cited by The Elec and reported by GSMArena, Samsung's M2700 will be paired with the Exynos 2700 in some Galaxy S27 models. An industry representative told The Elec that the modem reached performance comparable to, or better than, competing products after voltage adjustments and other design work.

The M2700 is said to remain on Samsung's 4nm process, yet use an optical die shrink to reduce its area by 4%. The report also describes a move from 3GPP Release 17 to Release 18 and improved non-terrestrial-network capabilities, which are used for satellite communications. These are reported specifications, not an official Samsung product announcement.

Why the claim needs context

Samsung's current Exynos Modem 5410 documentation describes a 4nm modem designed for lower standby power and improved efficiency. That provides useful product context, but it does not verify the M2700's alleged gains or predict how long a Galaxy S27 will last on a charge. Battery life will also depend on the phone's display, chipset, signal conditions, software and battery capacity.

The same reporting says Samsung is developing an M2800 modem on a 2nm process for future Galaxy S28 phones. Samsung has not publicly confirmed the M2700, its Galaxy S27 deployment plan or the M2800 timeline, so readers should treat those details as forward-looking reports.
