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.
