Samsung Galaxy S26 Ultra's battery to be bigger and charge faster

Samsung's Galaxy S26 Ultra is coming next year (most likely in January) and rumors are already swirling about it. Given how most of its Chinese competitors have recently upped the game significantly when it comes to battery capacity, you may have been wondering what to expect from the S26 Ultra.

If a tipster on X is correct, then Samsung's next flagship device is going to have a bigger battery than its predecessor's. But not by much. The S26 Ultra is said to employ a 5,500 mAh cell, vs. the S25 Ultra's 5,000 mAh.

That's still a 10% increase, but battery sizes starting with 6 and 7 are becoming the norm for Chinese brands, so this will clearly be seen as a weakness for the S26 Ultra when it arrives. On the flip side, it is said to support 65W charging, for the first time a Samsung smartphone is going to go past the previously-inescapable 45W threshold.

Of course we don't yet know what this will mean in terms of charging time and how much it will improve that, but it's good news nevertheless. We're also looking forward to finding out how much a Samsung 65W charger will cost, as naturally there won't be any such item in the phone's box.

Interestingly, while the battery capacity will increase, the S26 Ultra is said to be thinner than its predecessor's 8.2mm. And it will also support the recently unveiled Qi2 25W wireless charging standard - and 25W will be a record for Samsung smartphones in terms of wireless charging.
