The iPhone 17 has just arrived, bringing a 120Hz ProMotion display, a new 48 MP ultrawide camera (now defaulting to 24 MP), and a sharper 18 MP Center Stage selfie camera; plus faster wired charging.
But many buyers are asking: how does it stack up against the iPhone 16, a phone that still offers strong performance, dependable cameras, and now coming in at the lower price of $699 at Apple's website?
If you already own the iPhone 16 — or if you’re choosing between the two today — the big question is whether the iPhone 17 offers enough improvements to justify the upgrade. Spoiler alert, the answer is almost certainly a resounding "yes."
To find out just how much better the iPhone 17 is compared to the iPhone 16, we put both phones through our in-house tests for battery life, camera quality, display performance, and raw speed. We also spent quality time with them to see how they perform in daily use. Below, you’ll find our measured results and takeaways to help you decide which one is the smarter buy.

Design and Display Quality
Slightly larger, tougher, but familiar

The iPhone 16 kept Apple’s familiar aluminum-and-glass design with Ceramic Shield on the front. With the iPhone 17, Apple introduces Ceramic Shield 2, which is three times more scratch-resistant. Unlike the new iPhone Air and the iPhone 17 Pro models, though, the back is not made with Ceramic Shield 2.
The iPhone 17 is also marginally larger and heavier than the iPhone 16, mostly because of the bigger 6.3-inch display and slightly larger battery. In the hand, though, the difference is hardly noticeable; both still feel compact compared to most modern flagships.
| iPhone 17 | iPhone 16 |
|---|---|
| Thickness 7.95 mm | Thickness 7.8 mm |
| Dimensions 149.6 × 71.5 mm | Dimensions 147.6 × 71.6 mm |
| Weight 177 g | Weight 173 g |

Color options shift each year: the iPhone 16 offered Pink, Teal, Ultramarine, Black, and White, while the iPhone 17 switches to Black, Mist Blue, Lavender, Sage, and White. We especially liked the new Sage color, which feels more modern compared to last year’s palette.
Apple is more playful with the iPhone 17 colors, adding a:

The display is where the iPhone 17 will feel most different. The iPhone 16 was widely criticized for sticking with a 60Hz OLED panel, which was dimmer and less fluid than virtually all of its rivals. The iPhone 17 finally fixes that with a 6.3-inch LTPO OLED screen capable of 1–120Hz ProMotion, Always-On mode, and even comes with an anti-reflective coating.
The anti-reflective coating doesn't do as good of a job as the glass on the Galaxy S25 Ultra, but there is a noticable difference between the iPhone 17 and 16 when there are reflections on the screen.
Apple also increased outdoor brightness this year, with the iPhone 17 now peaking at 3000 nits outdoors, compared to 2000 nits on the iPhone 16. That said, both hit 1600 nits in HDR content.
As for biometrics, Face ID continues to be the only biometric option.
In our lab, the iPhone 17 peaked at 2672 nits (20% APL), clearly brighter than the iPhone 16 at 2015 nits. Both are similar in full-screen brightness (just over 1000 nits). Color accuracy also improved slightly, with the iPhone 17 showing a lower Delta E for colors (1.85 vs 2.16), although that result can vary from unit to unit, so yours might very well be different. All of this makes the iPhone 17 easier to use outdoors and a touch more accurate for content creators.
Performance and Software
A19 chip brings refinements, but AI remains a question mark
The iPhone 16 debuted Apple’s A18 chip, which was already a 3nm powerhouse. The iPhone 17 comes with the newer A19, bringing better efficiency and stronger sustained performance. Both phones come with 8 GB RAM, but the iPhone 17 doubles the base storage to 256 GB while keeping the same price, which is one of Apple's smartest moves with this year's base model, as it gives it an advantage compared to competitors.
On the software side, both models run iOS 26, which introduces the new Liquid Glass design language, Live Translation, Call Screening, and Apple Intelligence features powered by on-device AI.
| iPhone 17 | iPhone 16 |
|---|---|
| Chip A19 | Chip A18 |
| Process 3nm | Process 3nm |
| RAM, Storage --- 8/256GB 8/512GB LPDDR5X RAM NVMe storage | RAM, Storage 8/128GB 8/256GB 8/512GB LPDDR5X RAM NVMe storage |
The iPhone 17 comes with iOS 26, which introduces the flashy new “Liquid Glass” design language and long-overdue quality-of-life features like Call Screening, Live Translate, and smarter Messages. The same is true for the iPhone 16, so you are not losing anything by staying with, or going for the older model.
CPU Performance Benchmarks:
The A19 pulls ahead in Geekbench single-core (3527 vs 3264) and multi-core (8798 vs 7899). The difference isn’t massive, but you’ll notice smoother app launches and less stutter under heavier loads.
GPU Performance:
In 3DMark Extreme, the iPhone 17 scores 5172 high / 3295 low, a clear jump over the iPhone 16’s 4029 / 2397. This means the iPhone 17 is much more capable when it comes to graphically intensive tasks such as gaming or any work with video/photo editting software.
We did meet some hiccups during our initial benchmark testing with the iPhone 17, as it throttled quite early in our first perfrmance tests. In later tests, however, we did not encounter this issue.
Camera
Sharper ultrawide, much better selfies
We expected better results, but the differences are actually not that obvious. | Image credit — PhoneArena
The iPhone 16 introduced the vertical camera layout but kept the same 48 MP main and 12 MP ultrawide image sensors that came with the iPhone 15. With the iPhone 17, the ultrawide camera has been upgraded to 48 MP.
This is essentially the same ultrawide sensor as that one on the iPhone 16 Pro models, but it is now capable of producing 24 MP photos thanks to iOS 26’s new multi-aspect capture pipeline (a feature that Apple has also extended to the iPhone 16 Pro and Pro Max).
On the front, the iPhone 17 introduces an 18 MP selfie camera with Center Stage.
All of these camera upgrades should mean visible improvements when comparing these two phones, right? Well, as you will see from our camera score and samples, that's not exactly the case.
There's also a new Dual Capture feature on the iPhone 17, which lets users record simultaneously with the front and rear cameras.
PhoneArena Camera Score:
The iPhone 17 came only slightly ahead of the iPhone 16 in our Camera Score (150 vs 149). The gains come mostly from the main and ultrawide sensors, plus video stabilization. Selfie and zoom scores remain identical. The iPhone 16 already delivered solid image quality, and — when it comes to real world performance — it is not that much different to the iPhone 17.
Main Camera
The only noticeable difference here is that the iPhone 17's image is more saturated, which makes it feel more processed compared to the iPhone 16. Personally, I prefer the 16's look.
Zoom Quality
Here the iPhone 17's HDR pipeline seems to have performed better, showing more in the shadows. Again, it's also more saturated.
Ultra-wide Camera
The iPhone 16 seems to favor exposing for the shadows while the 17 for the highlights, with the former shoing more information in the darker areas and the latter in the brighter ones. The colors from the new ultrawide camera on the iPhone 17 look oversaturated, just like the ones from the main sensor.
Selfies
In this scenario, the iPhone 17’s tendency to oversaturate is its biggest enemy, as it makes the skin tones look almost comical. The iPhone 16 delivers far more natural-looking skin tones.

Battery Life and Charging
More hours, faster charging

Apple quotes 30 hours of playback for the iPhone 17, but our tests actually show worse overall battery life compared to the iPhone 16. Things have definitely improved when it comes to wired charging speed, though.
PhoneArena Battery and Charging Test Results:
Battery life is a close call: 6h 02min for the iPhone 17 vs 6h 21min for the iPhone 16. The older model still pulls ahead thanks to its performance during our Gaming test (9h 52m vs 7h 40m).
But where the new model shines is charging: the iPhone 17 goes from 0–100% in just 1h 16min, compared to 1h 42min on the iPhone 16. In our 30-minute test, it reached 67%, clearly ahead of the iPhone 16’s 59%. Wireless charging remains capped at 25W on both, but if you value faster top-ups, the iPhone 17 is the much better pick, and it's kind of its saving grace given the slightly lower battery life.
Audio Quality and Haptics
Improvements, but not across the board
The iPhone 17 actually delivers one of the most noticeable upgrades in speakers this year. Compared to the iPhone 16, it sounds bigger and wider, with more bass presence and higher overall volume. Apple also cleaned up the whistling mids that made last year’s model sound a bit thin.
Haptics, powered by Apple’s Taptic Engine, remain as precise and tight as before across the lineup.

Summary

The iPhone 17 is the clear winner, but the iPhone 16 still holds its ground.
The main reasons that make upgrading to the iPhone 17 worth it are its 120Hz ProMotion display, faster charging, higher base storage, and the selfie camera.
The main reasons that make upgrading to the iPhone 17 worth it are its 120Hz ProMotion display, faster charging, higher base storage, and the selfie camera.
I'd say that if you are buying new, then just spend the extra $100 and get the iPhone 17. You are getting a much better deal for your money with the new model, as it is arguably the best iPhone from this year's lineup.
If you have an iPhone 16, though, you shouldn't feel too tempted unless you really want to move up from the severely outdated 60Hz refresh rate and you think that the new selfie camera would come in handy for your needs.
