A clear win for the Galaxy Note 20 Ultra: 108 MP against 48 MP. Few specs in this matchup are as one-sided. More megapixels on the main camera allow bigger crops and more detail in good light, but sensor size and processing matter just as much.
-

Display
iPhone 15 Pro Max leads
The display comparison is one-sided. The iPhone 15 Pro Max leads where it counts. In its favor, the iPhone 15 Pro Max has 33% higher peak brightness. Peak figures are usually reached only in short bursts or small areas of the screen, but a higher ceiling still helps outdoor visibility. The Galaxy Note 20 Ultra stands out with 7.8% sharper pixel density. For anyone who cares most about display, the iPhone 15 Pro Max is the safer choice.
Peak brightness
iPhone 15 Pro Max: 2,000 nits Galaxy Note 20 Ultra: 1,500 nits If you use your phone outdoors a lot, the iPhone 15 Pro Max’s brighter panel is the one that holds up better at midday.
Pixel density
iPhone 15 Pro Max: 460 ppi Galaxy Note 20 Ultra: 496 ppi The Galaxy Note 20 Ultra packs its pixels more tightly, which shows most in small text, fine patterns and zoomed-in photos.
Performance
iPhone 15 Pro Max leads
By a small margin, the iPhone 15 Pro Max is the stronger of the two in this area. Point to the iPhone 15 Pro Max for a newer 3 nm chip process. A finer process node generally lets a chip do the same work with less power, which can mean cooler running and better battery life. So if performance tops your list, lean toward the iPhone 15 Pro Max.
Process node
iPhone 15 Pro Max: 3 nm Galaxy Note 20 Ultra: 7 nm The iPhone 15 Pro Max’s chip is built on a more advanced process. That usually points to efficiency gains, though chip design matters just as much.
CPU cores
iPhone 15 Pro Max: 6 Galaxy Note 20 Ultra: 8 Treat the core count as background information; the chipset name tells you far more about real performance.
Memory & Storage
iPhone 15 Pro Max leads
On memory & storage, the gap between these two is wide, and it favors the iPhone 15 Pro Max. Here the iPhone 15 Pro Max offers 256 GB of base storage instead of 128 GB. Base storage is what you get without paying extra. Photos, videos and apps add up quickly, so more space at the entry price is real value. On the Galaxy Note 20 Ultra, you get a microSD slot. The memory & storage verdict goes to the iPhone 15 Pro Max.
Base storage
iPhone 15 Pro Max: 256 GB Galaxy Note 20 Ultra: 128 GB The iPhone 15 Pro Max starts with more room, which means fewer “storage full” warnings and less time deleting old videos.
Max storage
iPhone 15 Pro Max: 1 TB Galaxy Note 20 Ultra: 512 GB The top storage option only matters if you plan to buy a high-capacity version, but it caps how much you can ever keep on the phone.
Camera
Galaxy Note 20 Ultra leads
The Galaxy Note 20 Ultra is the clear pick if camera is what you care about most. The Galaxy Note 20 Ultra answers with a higher-resolution 108 MP main camera. Megapixels are only one part of image quality, so treat this as a sign of detail potential, not a verdict on photos. Choose the iPhone 15 Pro Max and you get a sharper 12 MP selfie camera. Anyone shopping mainly on camera should start with the Galaxy Note 20 Ultra.
Main camera
iPhone 15 Pro Max: 48 MP Galaxy Note 20 Ultra: 108 MP The Galaxy Note 20 Ultra’s higher-resolution main sensor gives you more room to crop, which helps when you can’t get closer.
Front camera
iPhone 15 Pro Max: 12 MP Galaxy Note 20 Ultra: 10 MP A sharper selfie camera helps with video calls, vlogs and group selfies.
Battery & Charging
Too close to call
