Samsung appears determined to address one of the most persistent criticisms of its Exynos flagship devices: higher-than-expected standby battery drain. According to a new report, the company’s next-generation in-house modem, the M2700, is expected to deliver noticeably improved power efficiency when paired with the Exynos 2700 chipset in select Galaxy S27 models.
Exynos-based Galaxy phones have often been criticized for consuming more battery during standby than comparable Snapdragon models, largely due to modem power usage. However, Samsung LSI may now have found a solution. Industry sources speaking to The Elec claim the M2700 modem has reached performance levels equal to or better than rival products through optimizations such as voltage adjustment.
What makes the improvement especially notable is that the M2700 is still manufactured on Samsung’s 4nm process, the same node used for the Exynos Modem 5410 found in the Exynos 2600-powered Galaxy S26 lineup. Samsung is also reportedly moving away from the “Exynos Modem” branding in favor of a simpler M-series naming scheme for future modem products.
Even without a full process-node jump, the M2700 is said to be more power efficient. Samsung reportedly used an optical shrink to reduce the modem’s die area by around 4%. In addition to efficiency gains, the modem will support newer standards, moving from 3GPP Release 17 to Release 18. It also enhances Non-Terrestrial Network capabilities, which are important for satellite communication features.
Looking ahead, Samsung is already preparing its next modem, the M2800, expected to appear in Galaxy S28 models. That modem is expected to shift to a 2nm process, which should further improve power efficiency. The move to 2nm may also help Samsung free up 4nm production capacity, which the company plans to use for high-bandwidth memory components used in AI servers. Samsung currently uses its 4nm node for the base logic die at the bottom of HBM stacks.
Samsung LSI has continued refining its internal chip designs and is reportedly pushing Samsung’s mobile division to use more of its components in flagship Galaxy S devices. One ongoing discussion is whether the Galaxy S27 Ultra will use the Exynos 2700 chipset, a decision that could signal greater confidence in Samsung’s in-house silicon.
