Galaxy S26 ‘Pro’ and Edge battery specs leak, and they’re both getting upgrades
The base Galaxy S26 “Pro” will have a battery rated at 4,175 mAh. This is a 300 mAh increase from the existing Galaxy S25 which has a 4,000 mAh battery. Meanwhile, the Galaxy S 26 Edge would have a. 4,200 m Ah battery (rated 4,078 mAh)
GalaxyClub reports that the Galaxy S26 “Pro” – the confusing new name for Samsung’s base model of the series – will have a battery likely to be rated at 4,175 mAh, but advertised at 4,300 mAh. In other words, a 300 mAh increase from the existing Galaxy S25 which has a 4,000 mAh battery.
Meanwhile, Galaxy S26 Edge would have a 4,200 mAh battery (rated 4,078 mAh), which is also a 300 mAh increase over the existing Galaxy S25 Edge.
Obviously, the latter is getting the bigger upgrade. The larger display of Samsung’s Edge device means that the lower capacity can’t stretch as far, so the 8%~ increase will be more than welcome. But, for both devices, this is good news.

The Galaxy S26 Edge is expected to replace the Galaxy S26+ in Samsung’s lineup. It has the same size and roughly the same price point, but battery life is certainly going to continue to be a trade-off for the thinner form factor. All three of Samsung’s Galaxy S26 devices are expected to launch in January.

With Samsung tipped to ditch the base Galaxy S26 entirely and replace it with a Galaxy S26 Pro, there are some expectations that it will bring some upgrades that make it eligible for the ‘Pro’ tag. If a report from Galaxyclub.nl is accurate, it might arrive in the form of a battery upgrade.
The Galaxy S26 Pro will apparently launch with a 4,300 mAh battery (rated capacity). While it is larger than what the regular Galaxy S25 offers (4,000 mAh battery), it is far behind the Galaxy S25+ (4,900 mAh). It would be ideal if this came with an increase in charging Wattage, but leaks suggest it is limited to the Ultra model only.
Similarly, the Galaxy S26 Edge will also get a bump in battery capacity. Instead of the 3,900 mAh cell found on the Galaxy S25 Edge, it will launch with a 4,200 mAh battery. Exactly how much that will improve battery life remains to be seen, but any upgrade is welcome, given the S26 Edge might be thinner than its last-gen counterpart.
Given they are still months away from launch, not much is known about the Galaxy S26 Pro and Galaxy S26 Edge. One set of reports insists it will launch with Samsung’s next-gen Exynos 2600 SoC, while another implies it will stick with Qualcomm’s Snapdragon 8 Elite 2 for Galaxy.

Traditionally, Samsung’s Galaxy S series consists of three models: the base model, the Plus model, and the Ultra model. 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.

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.
Samsung Galaxy S26 Pro, Galaxy S26 Edge Latest Leak Indicates Major Battery Upgrade
The Galaxy S26 Pro and S26 Edge are expected to be launched in January. Rumors suggest they will have a larger battery capacity. The Galaxy S25 and S25 Plus have a 4,000 mAh battery. The S26 is expected to have a battery of 4,200 mAh.
It is believed that Samsung may do away with the standard and Plus versions and instead introduce the Galaxy S26 Pro and Galaxy S26 Edge in its new lineup.
The Galaxy S26 Pro and Galaxy S26 Edge are likely to see a modest enhancement compared to the existing Galaxy S25 and S25 Edge models.
As reported by the Dutch website GalaxyClub, the Samsung Galaxy S26 Pro is said to come with a battery rated at 4,175 mAh, with Samsung likely to promote it as having a capacity of 4,300 mAh.
Should this information turn out to be correct, this would mark a modest improvement over the 4,000 mAh battery offered in the Galaxy S25. It is worth noting that the newly introduced Galaxy Z Flip 7 also has a 4,300 mAh battery.
Moreover, the report suggests that the Samsung Galaxy S26 Edge will feature a battery with a rated capacity of 4,078 mAh, which Samsung is expected to advertise as 4,200 mAh.
Leak Reveals Big Battery Boost for Galaxy S26 Edge and S26 Pro
Samsung looks set to upgrade the battery on the Galaxy S26 Edge to 4,200mAh — a noticeable bump from the 3,900mAh unit in the S25 Edge. The Galaxy S 26 Pro, which replaces the base model, may feature a slightly larger 4,300mAh battery. Meanwhile, the Ultra model is likely to retain its reliable 5,000mAh capacity. Samsung may rebrand its flagship lineup next year. Instead of a base-Plus-Ultra setup, we may get a Galaxy S24 Pro, an S25 Pro, and an S26 Ultra.
Galaxy S26 Edge and S26 Pro’s battery capacity revealed in new leak
Samsung may rebrand its flagship lineup next year. Instead of a base-Plus-Ultra setup, we may get a Galaxy S26 Pro, an S26 Edge, and an S26 Ultra. This rebranding appears to be part of a broader strategic overhaul to enhance the appeal of flagship Galaxy smartphones. The new models are expected to bring major hardware upgrades across several key areas.
One such area could be the battery. While the Ultra may keep a 5,000mAh battery for the seventh generation in a row, the other two models may get notable upgrades. According to GalaxyClub, the Galaxy S26 Edge — codename M2, model number SM-S947 — has a rated battery capacity of 4078mAh, which should mean a typical capacity of 4200mAh.
As mentioned above, this year’s Galaxy S25 Edge has a 3,900mAh battery. The Edge model is all about a slim design with flagship specs. Samsung should maintain that formula with the next-gen offering, more so because it is being integrated in the main lineup in place of the Plus model. In fact, rumors suggest the next Edge will be slimmer than the S25 Edge (5.8mm), which makes a battery upgrade even more impressive.
The same source adds that the Galaxy S26 Pro’s battery has a rated capacity of 4175mAh, which typically equates to an advertised capacity of 4300mAh. Once again, we are looking at a 300mAh capacity boost compared to the base Galaxy S25. It’s unclear if the S26 Pro will be slimmer, though — the base S25 is 7.2mm thick.
Recent developments suggest Samsung will offer 60W charging on the Galaxy S26 Ultra, up from 45W on the S25 Ultra. It’s unclear if the Pro and Edge models will get the same super-fast charging. The company could limit them to 45W, which is still faster than the Galaxy S25 and S25 Edge (both 25W). Stay tuned for more updates.
