While rumors are still up in the air regarding a battery upgrade for the Galaxy S26 Ultra, new information has come out on the base Galaxy S26 “Pro” as well as the Galaxy S26 Edge, with both devices set to pack bigger batteries.

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.
