Key Differences
-
The Galaxy S24 has 3 years of extra promised updates
Among all the differences on this page, 7 years against 4 years is one of the most meaningful, and it favors the Galaxy S24. The Galaxy S24’s longer software support can also help its resale value later on.
-
The OnePlus 13 has 4 GB more RAM
The Galaxy S24 gives up a lot on ram: 8 GB, compared with 12 GB on the OnePlus 13. More RAM lets a phone keep more apps open in the background, so switching back to them is instant instead of a reload.
-
The OnePlus 13 has 50% more battery capacity
Few buyers will miss this one. The OnePlus 13 brings 6,000 mAh to the table; the Galaxy S24 brings 4,000 mAh. A bigger battery usually means longer days between charges, although chip efficiency and screen size also shape real endurance.
-
The Galaxy S24 has a 1.52 oz lighter build
When it comes to weight, the Galaxy S24 wins comfortably with 5.89 oz against 7.41 oz. Weight shows up every time you hold the phone above your face in bed or type one-handed for a long stretch.
-
The OnePlus 13 has 256 GB of base storage instead of 128 GB
It’s a lopsided result (256 GB for the OnePlus 13, 128 GB for the Galaxy S24) and one of the main reasons to choose between them. 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.

Peak brightness
OnePlus 13: 4,500 nits Galaxy S24: 2,600 nits Peak figures are usually reached only in short bursts or small areas of the screen, but a higher ceiling still helps outdoor visibility.
Screen size
OnePlus 13: 6.8 in Galaxy S24: 6.2 in A larger display also means a larger phone overall, so this is as much about your hands and pockets as it is about the picture.
Performance
OnePlus 13 leads
This is one of the OnePlus 13’s strongest areas. On performance, the Galaxy S24 falls well short. The OnePlus 13 has the edge with 4 GB more RAM. Opening a single app, you won’t feel the difference.

OnePlus 13: 12 GB Galaxy S24: 8 GB Extra memory also gives the OnePlus 13 more headroom for heavier apps and for software updates in the years ahead.
Process node
OnePlus 13: 3 nm Galaxy S24: 4 nm The OnePlus 13’s chip is built on a more advanced process. That usually points to efficiency gains, though chip design matters just as much.

OnePlus 13 leads
The memory & storage comparison is one-sided. The OnePlus 13 leads where it counts. The OnePlus 13 stands out with 256 GB of base storage instead of 128 GB.

Base storage
OnePlus 13: 256 GB Galaxy S24: 128 GB If you shoot a lot of video or keep music and maps offline, base storage is one of the specs you’ll feel most over the years.
Camera
OnePlus 13 leads
Look at the camera table and one name keeps coming out on top: the OnePlus 13. On its side, the OnePlus 13 has a dedicated 50 MP telephoto camera. A dedicated telephoto camera captures distant subjects and portraits without heavy cropping, which keeps detail intact. Bottom line for camera: the OnePlus 13 has the edge.
Telephoto camera
OnePlus 13: 50 MP Galaxy S24: 10 MP A higher-resolution telephoto keeps more detail when you zoom, and gives the OnePlus 13 a stronger tool for portraits and distant subjects.

OnePlus 13: 50 MP Galaxy S24: 12 MP A sharper ultra-wide keeps more detail at the edges of landscape, architecture and group shots.
Battery & Charging
OnePlus 13 leads

Battery capacity
OnePlus 13: 6,000 mAh Galaxy S24: 4,000 mAh Capacity isn’t everything, but when two phones are otherwise close, more milliamp-hours is the simplest endurance advantage there is.
Wired charging
OnePlus 13: 80 W Galaxy S24: 25 W The OnePlus 13 refills faster on a cable, which matters most on the mornings you forgot to charge overnight.
Software & Updates
Galaxy S24 leads
The Galaxy S24 wins the software & updates section decisively. The Galaxy S24 gives you 3 years of extra promised updates. Software support is what separates a phone that ages gracefully from one that doesn’t, making it one of the most practical lines on the spec sheet. If this section decides it for you, choose the Galaxy S24.
Promised OS updates
OnePlus 13: 4 years Galaxy S24: 7 years A longer update promise keeps the phone secure and current for longer, which matters if you keep devices for several years.
