Galaxy S23 Ultra Review: The Zoom Camera Nobody Else Has

A 200-megapixel sensor and a 10x zoom lens that makes the moon look closer than it has any right to.

Editor's Verdict - Essential

The best camera system on any phone right now, wrapped around a big, capable Android flagship that finally fixed its own worst habit.

The S23 Ultra picks up right where the S22 Ultra left off in shape, the built-in S Pen, the squared-off Note-inspired body, the same overall silhouette, but the changes underneath matter more than the familiar look suggests. Samsung swapped in a 200-megapixel main sensor, up from 108MP, and paired it with a dedicated Snapdragon 8 Gen 2 for Galaxy chip tuned specifically for this phone rather than a shared reference design.

That 200MP sensor is the headline, but the number itself isn't really the point. By default, the camera bins those pixels down into a sharper 12MP shot with genuinely better detail and noise handling than the S22 Ultra managed, and you can shoot at the full 200MP resolution when you actually want to crop deep into a shot after the fact. Both modes work as advertised, which isn't something I can say about every phone that's chased a big megapixel number for a headline spec.

I've photographed the moon with visible surface detail on a phone, which is an absurd sentence to type.

The zoom is where this phone still stands alone. A 10x optical zoom lens, on top of a 3x telephoto, lets you get usably close to something across a stadium or a backyard without the mush most phones produce past 5x. I've photographed the moon with visible surface detail on this thing, a genuinely absurd thing for a phone camera to pull off, and everyday use, zooming into a stage at a concert or a bird across a yard, holds up nearly as well.

Low-light performance took a real step forward too. Nightography mode handles dim restaurants and evening shots without the smeared, over-processed look a lot of computational night modes produce, and it does it fast enough that you're not standing there holding the phone steady for three seconds waiting on a long exposure.

The S Pen is still built into the chassis, still free of the Bluetooth features Samsung dropped from cheaper standalone pens, and it remains genuinely useful for anyone who takes handwritten notes or marks up a screenshot regularly. It's a feature you either already rely on or never think about, and the S23 Ultra doesn't change that calculus from previous models.

Battery life is the quiet win of this generation. The Snapdragon 8 Gen 2 for Galaxy chip runs noticeably cooler and more efficient than the exynos-flavored chips Samsung shipped in some regions previously, and I've consistently gotten through a full day of heavy use, camera-heavy at that, with battery left at bedtime. 45W fast charging gets you to 65 percent in about twenty-five minutes when you do need to top up.

The 6.8-inch display remains one of the best on any phone, a 120Hz adaptive refresh Dynamic AMOLED panel that peaks at 1,750 nits, bright enough to actually read outdoors in direct sun, which sounds like a small thing until you've squinted at a dimmer phone screen at a bus stop in July.

The size and weight are the real tradeoff here, and Samsung hasn't hidden from it. At 234 grams, it's a genuinely large, heavy phone, and anyone with smaller hands or a preference for one-handed use is going to feel that every day, not just on the first unboxing. There's no getting around it: this is a two-hand phone.

A year into its release cycle, the price has come down from launch and the software has matured through several updates, which makes it an easier recommendation now than it was on day one. For anyone who actually uses a zoom lens, shoots in a lot of low light, or wants the S Pen without stepping up to a genuine tablet, this remains the best camera system on any phone you can buy, full stop.

Still going strong a year and a half after I bought it, battery's barely degraded. Took photos at my daughter's graduation from the back row that look front row. Best phone I've owned.

The moon shots are partially synthesized, scene optimizer recognizes the moon and reconstructs detail, this was documented years ago and people still post them as camera proof. The 10x periscope glass is still unmatched, which I confirmed with about 400 test shots of things that aren't the moon. Buy it for the zoom, not the astronomy.

Phones peaked when batteries were removable. This one weighs as much as two of my old ones stacked. Camera's genuinely good, I'll grant that. My S9 also made calls and fit in a pocket.

Shot a whole concert from the cheap seats with the 10x and my friends thought I was backstage. The zoom is a party trick that never stops landing. Heavy phone but you stop noticing in a week.

I bought it for the camera but stayed for the S Pen, I doodle on screenshots constantly now and take handwritten notes at the plant nursery. Night mode caught a moth on our porch light with the fuzz visible. It's a chunky phone but so am I in spirit.

Great phone, does everything, battery lasts all day like the review says. Docked one star because it's genuinely huge, my thumb can't reach half the screen. You adjust, but you notice.

The for Galaxy chip is a binned 8 Gen 2 clocked 150MHz higher, it's real but it's a rounding error in daily use, the efficiency gain is the actual story. Thermals under sustained camera use are the best Samsung's shipped. I traded mine for the S24 Ultra three weeks after posting a comment explaining why upgrading this cycle was irrational.

Twelve hundred dollars for a phone. Then a case because it's glass, then insurance because it's twelve hundred dollars. The moon photos are neat. So was calling my brother on a phone that cost forty bucks.
