Samsung is gearing up to launch its Galaxy S26 series in January 2026, but anticipation and leaks about the new smartphones are already generating buzz online.
Recent reports suggest that Samsung may replace the standard plus variants with new Galaxy S26 Pro and Galaxy S26 Edge models, indicating a significant shift in the lineup.
A recent leak from GalaxyClub has disclosed the battery capacity details for the upcoming devices. The Galaxy S26 Pro is expected to have a rated battery capacity of 4,175mAh, although Samsung may market it as 4,300mAh. This represents a modest upgrade from the Galaxy S25’s 4,000mAh battery. Interestingly, the recently released Galaxy Z Flip 7 also features a 4,300mAh battery.
Rumours suggest the Galaxy S26 Edge will feature a 4,078mAh battery, likely marketed as 4,200mAh. This upgrade improves on the Galaxy S25 Edge’s 3,900mAh battery, which faced criticism for its slim design restricting battery capacity. Reported codenames for these models are M1 (Galaxy S26 Pro, model SM-S942) and M2 (Galaxy S26 Edge, model SM-S947).

However, analysts suggest that Samsung is planning to revamp the S26 lineup. Instead of the standard and models, the company is likely to introduce Galaxy S26 Pro and S26 Edge variants alongside the Galaxy S26 Ultra.
The Galaxy S26 Ultra will keep a 5,000mAh battery and 60W fast charging support, matching its predecessor. All Galaxy S26 variants will also include a 16GB RAM option worldwide.
Leaked information suggests that the Galaxy S26 Edge will feature a slimmer, more refined design compared to the S25 Edge and will utilise new battery material technology. Camera upgrades may include a 50-megapixel ultra-wide sensor. Samsung appears to be working on enhancing battery performance and design while refreshing the Galaxy S series lineup to keep its competitive position in the flagship smartphone market.
