Key Differences
-
The OnePlus 15 has a 165 Hz display instead of 120 Hz
For refresh rate, the OnePlus 15 leads by a wide margin: 165 Hz versus 120 Hz. Smoother motion is one of the most visible display upgrades, and adaptive high-refresh panels can slow down on static content to save power.
-
The iPhone 17 Pro Max has 4× optical zoom versus 3.5×
A narrow win for the iPhone 17 Pro Max. With 4× to 3.5×, it’s the kind of difference that adds up rather than stands out. The iPhone 17 Pro Max reaches further with real optics, which pays off for wildlife, stages and sports from the stands.
-
The OnePlus 15 has a 0.78 oz lighter build
Close, but not identical: the OnePlus 15 lists 7.44 oz and the iPhone 17 Pro Max lists 8.22 oz. The OnePlus 15 is easier on your wrist during long reading or gaming sessions.
-
The iPhone 17 Pro Max has a bigger top storage option
This is a headline difference. With 2 TB to the OnePlus 15’s 512 GB, the iPhone 17 Pro Max has a lead that’s easy to see on paper and in practice. 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.
-
The OnePlus 15 has faster 50 W wireless charging
Put simply, the OnePlus 15 is far ahead here: 50 W compared with 25 W. Faster wireless charging makes a pad or stand more practical as your main way to top up.

Display
OnePlus 15 leads
This section belongs to the OnePlus 15. In display, it leads the iPhone 17 Pro Max by a margin that’s hard to ignore. Choose the OnePlus 15 and you get a 165 Hz display instead of 120 Hz. You notice refresh rate every time you scroll a feed or a web page, which is why the OnePlus 15 feels more fluid in everyday use. That makes the OnePlus 15 the natural choice for buyers focused on display.
Refresh rate
OnePlus 15: 165 Hz iPhone 17 Pro Max: 120 Hz A higher refresh rate makes scrolling, animations and games look smoother. Once you’re used to it, a lower-rate screen can feel sluggish by comparison.
Performance
Too close to call
Swap one for the other and you’d lose nothing on performance. In short, performance is a draw; the decision lies elsewhere.
CPU cores
OnePlus 15: 8 iPhone 17 Pro Max: 6 Phone chips mix large and small cores, so a different count mostly reflects a different design rather than a clear speed gap.
Memory & Storage
iPhone 17 Pro Max leads
The iPhone 17 Pro Max does a little better in the memory & storage section, though nothing here is a deal-breaker for the OnePlus 15. The iPhone 17 Pro Max answers with a bigger top storage option. Heavy video shooters and people with large offline libraries benefit from the iPhone 17 Pro Max’s bigger maximum. In short, the iPhone 17 Pro Max is the better-equipped phone for memory & storage.
Max storage
OnePlus 15: 512 GB iPhone 17 Pro Max: 2 TB Most buyers are fine with a base or middle tier, so this is a niche advantage, but a real one if you need it.
Camera
Trade-off
This area is a trade-off. Choose the OnePlus 15 for a sharper 32 MP selfie camera, or the iPhone 17 Pro Max for 4× optical zoom versus 3.5×. Bottom line for camera: decide which advantage matters more to you.
Optical zoom
OnePlus 15: 3.5× iPhone 17 Pro Max: 4× Higher optical zoom lets you frame distant subjects tightly without losing detail to digital cropping.
Front camera
OnePlus 15: 32 MP iPhone 17 Pro Max: 18 MP If you mainly use the front camera for calls, the gap is minor; if you post selfies often, the OnePlus 15’s extra resolution helps.
Battery & Charging
OnePlus 15 leads
If you’re keeping score, the battery & charging point goes narrowly to the OnePlus 15. The OnePlus 15 has the edge with faster 50 W wireless charging. If you rely on a wireless pad at your desk or bedside, the OnePlus 15 refills quicker there. The takeaway: on battery & charging, the OnePlus 15 is the stronger phone.
Wireless charging
OnePlus 15: 50 W iPhone 17 Pro Max: 25 W Wireless charging is usually slower than a cable, so this edge matters mainly to people who value the convenience.
Software & Updates
On software & updates, the useful details are the names in the table: what each one uses, not a figure we can rank.
