Samsung’s 30-hour claim is fantasy—but Panther Lake battery life is still wild

Samsung says its Galaxy Book6 Ultra gets “up to 30 hours” of battery life thanks to Intel’s Panther Lake hardware. But that’s a pretty bold claim.

Laptop battery life is slippery, after all. Promises from manufacturers that push above 24 hours of battery life are becoming increasingly untethered from real-world computer usage. If you were to use the Galaxy Book6 Ultra, you’d reach nowhere near that.

I tested it out myself and it didn’t get all the way there. But I’m still impressed by Core Ultra Series 3 hardware!
