We’ve got the Samsung Galaxy S24 Ultra in-house and have been using it since Unpacked. And now we’ve just finished running our battery test on the Galaxy S24 Ultra. The results were, quite frankly, very surprising in a good way. It completely destroyed the iPhone 15 Pro Max, which was our battery champ, before the Galaxy S24 Ultra.

First, let’s talk a bit about the battery test that we run on every phone that we review. Essentially, we run a YouTube video at full brightness from 100% down to about 1% (and then we can perform our charging test). We do this because sitting there running apps for a certain length of time over and over doesn’t really work that well when comparing phones, as there are so many variables in that kind of testing. But doing this exact same test does work well, especially on brighter phones like the Galaxy S24 Ultra.

The Galaxy S24 Ultra battery life results

Our previous top score in this test was the iQOO 12, which had a score of 21 hours and 52 minutes. Followed by the iPhone 15 Pro Max at 21 hours and 35 minutes. The brand new OnePlus 12, which we just published that review, scored 19 hours and 7 minutes to put it in third place.

But the Galaxy S24 Ultra just surpassed them all. It finally hit 1% at 25 hours and 35 minutes. That crushes just about everything we’ve tested here. Even other Snapdragon 8 Gen 3-powered phones like the iQOO 12, OPPO Find X7 Ultra, and the OnePlus 12. It’s honestly very impressive.

Our real-life results

So a battery rundown is one thing, but what about our use in the real world, using it as our daily driver? It’s still quite impressive. The other day, I was able to get just over 10 hours of screen time, with 21% left. That means it could have easily hit 12 hours of more on a single charge. That’s quite impressive on its own and far above what most other phones I’ve reviewed have been able to do.

Of course, we’ll have more about this in the full review next week. But so far, it’s looking like the Galaxy S24 Ultra is going to be the new Battery Champ.
