The Samsung Galaxy S26 Pro is also getting a battery upgrade, it’s not just the S26 Edge
The Samsung Galaxy S26 Pro will reportedly have a battery with 4,300mAh typical capacity. That would be 300mAh more than the S25 and S24. The S26 Edge (M2, SM-S947) will also get a battery bump to 4,200mAh. And it will be even thinner than the current 5.8mm model. We’ve heard that the Galaxy S 26 Ultra will finally go above 45W – all the way up to 60W. This may or may not come with a capacity upgrade – some sources claim a 10% bump to 5,500mAh, others say it will stay at 5,000mAh.
As you may have heard, the vanilla Galaxy S model is going away – and that is great news because it will be replaced by a more capable Pro model. What improvements can we expect? A larger battery, for starters.
The Samsung Galaxy S26 Pro will reportedly have a battery with 4,300mAh typical capacity. That would be 300mAh more than the S25 and S24 and 400mAh more than the S23.
The Galaxy S25 has only 4,000mAh battery capacity
The S26 Pro is code-named M1 and will have a model number SM-S942. We’ve heard that the 50MP ISOCELL GN3 sensor will be replaced (it was used in the S23, S24 and S25), but this may not bring a resolution upgrade. The ISOCELL GN5, for example, is a 50MP 1/1.56” sensor with 1.0µm pixels – not too different from the GN3. However, the GN5 has improved autofocus performance and it introduced Front Deep Trench Isolation to Dual Pixel sensors – sensor upgrades aren’t all about resolution, you know.
As previously reported, the Samsung Galaxy S26 Edge (M2, SM-S947) will also get a battery bump to 4,200mAh typical capacity, 300mAh more than the S25 Edge. And it will be even thinner than the current 5.8mm model.
You can’t help but wonder whether these new batteries will be paired with a charging speed upgrade. We’ve heard that the Galaxy S26 Ultra will finally go above 45W – all the way up to 60W. However, this may or may not come with a capacity upgrade – some sources claim a 10% bump to 5,500mAh, others say it will stay at 5,000mAh.

We haven’t heard anything about a charging upgrade to the S26 Pro and S26 Edge and given their battery capacities – around the same as the Z Flip7 (4,300mAh) and Z Fold7 (4,400mAh), both of which are capped at 25W – we don’t expect anything to change. We wouldn’t mind being surprised, though.

IceUniverse: Samsung Galaxy S26 Edge to pack a 4,400 mAh battery
The Galaxy S26 Edge has been the subject of numerous rumors lately, with several concerning its battery capacity. Previous rumors have hinted that Samsung will increase the phone’s battery capacity to 4,200 mAh, which would be a solid upgrade over the S25 Edge and its 3,900 mAh cell.
According to the latest leak, the S26 Edge will arrive with a 4,400 mAh battery. Note that the tipster’s latest post acknowledges conflicting information surrounding the S26 Edge’s battery capacity, so take this info with a few grains of salt.
Other rumors about the S26 Edge suggest it will be even thinner than its predecessor, which comes in at 5.8mm. The upcoming S26 Edge is expected to gain a 50MP ultrawide lens and a chipset upgrade, but it remains to be seen if it will be an Exynos or a Snapdragon.

Battery war brewing inside Samsung’s Galaxy S26 series
Samsung is shaking up the Galaxy S26 lineup, bringing Pro, Edge, and Ultra rather than Base and Plus. Recently, a report revealed the battery capacities of the S26 Pro and Edge models, but a new rumor sparks confusion. Leaker Phoneart (Ice Universe) reports that theGalaxy S26 Edge’s battery could be 4,400mAh. The same source revealed Galaxy S25 base model and S25 Edge support up to 25W fast charging.
Leaker Phoneart (Ice Universe) reports that the Galaxy S26 Edge’s battery could be 4,400mAh. It’s 200mAh more than what GalaxyClub reported earlier. The same source revealed Galaxy S26 Pro battery capacity to be 4,300mAh.
That said, the Galaxy S26 Pro, which is an entirely new variant, would not offer the best battery performance between the two non-Ultra models. However, tipster Ice will come up with an update after verifying the details with his sources.
Battery capacities of the S26 models (rumored)
Galaxy S26 Pro – 4,300mAh
Galaxy S26 Edge – 4,200mAh or 4,400mAh
Galaxy S26 Ultra – 5,000mAh
The first battery revelation exposed that Edge had the smallest battery in the lineup. The Galaxy S26 Ultra is all set to retain a 5,000mAh battery with Samsung’s fastest charging, 60W, for significantly shorter waits for battery recharge.
Details on battery size have started to appear, but we haven’t yet heard about the charging speed of the S26 Pro and Edge. The S25 base model and S25 Edge support up to 25W fast charging, and we are expecting an upgrade in this aspect.
Galaxy S26 Series

This week, a lot of future Samsung products have emerged with genuine backing. Samsung is dropping the base and Plus flagships, starting with the Galaxy S26 series, with a new Pro is getting added and Edge replacing Plus.
The Galaxy S26 Ultra will be even more powerful to lead the lineup next year. There may be another affordable option, the S26 FE, which would launch later next year. For the Galaxy S26 series, we expect an official launch around February.
Samsung Galaxy S26 Pro and S26 Edge battery sizes leak
GalaxyClub claims the Galaxy S26 Pro will feature a rated battery capacity of 4,175mAh. Samsung will likely advertise this as a 4,300mAh cell — the same as the Galaxy Z Flip 7. Expect the phone to feature a display measuring around 6.4 inches or smaller. If accurate, that would bring a 300mAh boost in capacity over the S25 Edge’s 3,900mAh cell. The phone will supposedly support 60W wired fast charging, making it one of the fastest-charging Galaxy devices around when it debuts next year.

Based on the battery capacity and the naming scheme, it’s now clear that the S26 Pro will be like the iPhone 16 Pro and Google Pixel 9 Pro, a compact flagship. So, expect the phone to feature a display measuring around 6.4 inches or smaller.

For comparison, the iPhone 16 Pro features a 6.3-inch display and a 3,582mAh battery, while the Pixel 9 Pro, with the same display size, packs a significantly larger 4,700mAh cell. Even the base Galaxy S25, which houses a 6.3-inch display, packs a 4,000mAh cell. So, the S26 Pro should be around the same size as the S25 or just slightly bigger, enabling Samsung to fit in a 300mAh bigger cell.
Galaxy S26 Edge may get a welcome battery capacity boost
The S25 Edge in all three colors.
As for the S26 Edge, the report claims Samsung will equip it with a 4,078mAh battery but market it as a 4,200mAh cell. If accurate, that would bring a 300mAh boost in capacity over the S25 Edge’s 3,900mAh cell. This should lead to a noticeable boost in battery life, though the phone will likely still struggle to make it through a day of use if Samsung does not optimize other aspects for power efficiency.
The alleged battery capacity of the Galaxy S26 Ultra has also already leaked, indicating it will use the same 5,000mAh cell as Samsung’s last few Ultra flagships. On the bright side, the phone will supposedly support 60W wired fast charging, making it one of the fastest-charging Galaxy devices around when it debuts next year.
