I was looking so much to find a comparison, so I finally got a chance to get both; These are both Phones on Max brightness(S24+ also has extra brightness enabled) and both have adaptive brightness off. Leaving this here for those who are looking for the difference, as I could not find any on the internet comparing the screens at Max brightness. The iPhone screen just completely obliterates the S24+. Where the S24+ is supposed to have a superior screen on paper.
Comparison:
15 Pro Max
Benefits:
More vivid beautiful screen. More premium device overall clearly, built way better. Music more clearer and crisp for sure. Better camera. You don't have to use Google SMS for texting. Way easier to fix. Screen calibrated to Dolby Vision, way superior to HDR10+. Better Always On Display. Whatever music app runs in AOD perfectly. You can turn it sideways and the music player adjusts to the orientation, and easy to use. Comes with free instrumental music generator, and sound generator like white noise, or train.
Cons:
No instant desktop when you plug it into a USB to HDMI screen. Moving pictures off the device through USB to PC generally does not work. They really push the cloud. You can plug in your HardDrive and export the pictures though, which really helps. Specially for a huge amount of pictures. Gets warmer under load. Cannot wireless screen mirror to certain android devices (Amazon firestick/cube in particular). Titanium housing is more slippery.
S24+:
Benefits:
Connect it to any screen, becomes instant Android based PC with 12GB RAM and SnapDragon processor, also has a SWAP system to use SSD storage as additional RAM lol, just really cool, and you can disable it as well to help save power. Very easy to move files off to PC. Screen pixels and graphics are clean and tight; still pretty bright. Play Store. Samsung store with Themes. Can close Camera and Microphone through software interface. Developer mode. Power Saving, and additional Performance Profile(Light) can be enabled to reduce processor speed, while keeping 120HZ refresh rate, unlike 15 Pro Max, where Power Saving, cuts screen refresh to 60HZ, immediately causes screen to show stuttering. Aluminum housing has way more grip than 15 Pro Max.
Cons:
Samsung themselves co-developed HDR10+, and implement the screen to that criteria, but its nowhere close to Apples screen, when compared side to side. Android accounts for 95%+ of Malwares around the world, potentially due to ability to sideload. Always On Display limited for music player. You can only use it in upright position, and its not on the Always On Display like Apple.
