Update: There's been another source that backs up the 5,000 mAh battery claim for the S23 Ultra.
While Samsung's focus these days is on its Samsung Unpacked event this week, that's not stopping Galaxy S23 rumors from bubbling to the surface — yes, even though we're not likely to see that latter device until early next year.
Already, the Ultra version of the Galaxy S23 is rumored to be getting an all-new 200MP camera, and that same leaker has some details about the flagship phone's chipset and battery specs.
It's another Ice Universe claim that made us sit up, though. The leaker also says that the S23 Ultra will get a 5,000 mAh battery — the same size used by the Galaxy S22 Ultra as well as the Galaxy S21 Ultra before that.
Still, battery life might be a concern with the Galaxy S23 Ultra, precisely because the Galaxy S22 Ultra didn't exactly impress with its battery life in our tests. The phone lasted 8 hours and 50 minutes, about an hour behind the average smartphone in our battery test, in which we have phones surf the web until they run out of power. Only when we turned off the adaptive refresh rate on the S22 Ultra's display did the phone turn in a more respectable time of 10 hours and 18 minutes.
If increasing the battery capacity isn't an option — and the Ice Universe leak would suggest that's off the table — Samsung could turn to some other methods to boost battery life for the S23 Ultra. For one, it could make its adaptive display feature more power-efficient since other phones that can scale up their refresh rate to 120Hz don't see as big a battery drain.
