iPhone 15 Pro vs iPhone 15: which one should you go for?

With each and every iPhone generation, one question looms over potential customers: should you go Pro or is the regular iPhone model sufficient for your needs?

The same scenario is valid for the iPhone 15 and iPhone 15 Pro in full force. While the iPhone 15 Pro has some obvious advantages like a dedicated telephoto camera and a new titanium design to boot, it's pricier than the regular iPhone 15 model, which has scored a 48MP main camera and the Dynamic Island that debuted on the previous generation. 

But worry not, we are here exactly for that reason — to make that choice an easier one for you! We have put the iPhone 15 and iPhone 15 Pro through our own camera and battery tests, making it easier to see exactly in what areas, and how much these two devices are different from one another. 

So buckle up, and let's figure out which iPhone is the best one for you.

Both the iPhone 15 Pro and iPhone 15 come with the same 6.1-inch screen size, which makes these phones quite compact in comparison to the Pro Maxes and Ultra phones of the world. We find that they are mostly OK to handle with one hand, but will require a double grip from time to time — these are definitely not iPhone mini levels of compact. 

While the screen sizes are the same, the 15 Pro has slimmer bezels so it looks more modern with that edge-to-edge styling, and it is also physically just a tiny bit narrower. Thus, a tiny bit easier to handle, though we found the matte frame and the titanium itself can feel a bit slippery against dry hands — something we notice during the current winter cold when we use the phone without a case.

Here are the exact sizes of these two:

As you can see, the iPhone 15 Pro is still a tiny bit heavier as well, but nowhere nearly as much as the previous Pro models. And this is actually our favorite new feature of the Pro, just how much lighter it has gotten!

This is thanks to the new titanium frame, instead of the stainless steel used in the past. Titanium is just as strong, but much lighter. Still, it's worth noting that the inside of the iPhone 15 Pro's frame is aluminum, and then there's about a millmeter (0.04") of titanium fused to it as an "outside shell". Despite this hybrid approach, you do get the benefit of dent protection and less fingerprints that titanium brings along!

The regular iPhone 15 model, on the other hand, uses a familiar aluminum frame which is noticeably softer than titanium, but assures the phone is light and easy to handle. Plus, it comes in a variety of fun colors, whereas the titanium models have a few muted options — even if they have that cool brushed finish.

Interestingly, the back of the regular iPhone 15 now has a smooth matte glass (previous vanilla iPhone models had glossy surface on the back). In fact, the iPhone 15's back is very similar to the matte glass on the back of the 15 Pro models.

One feature that only the iPhone 15 Pro gets, however, is the new Action Button, while the regular iPhone 15 still uses the good old mute switch. The new Action button is programmable, so you can set it to do a number of things. It defaults as a mute key, but the difference is that you can set it to start the camera, or even start any app or do something more complex via the Shortcuts app. You simply can't do that with the mute switch on the regular iPhone 15.

It's worth noting that the Action Button can only do the one thing though. It only accepts a "press and hold" gesture which gets assigned to whatever app or feature you pick for it. So, if you choose to have the Camera bound to the Action Button, you lose that on-demand muting function. Thankfully, there's a new Mute toggle found in the Control Center (swipe down from the top-right of the display). 

On the bottom, both phones feature a USB-C port, a welcome change from the Lightning port that Apple has been using for years. That's great news as this is the same cable most other electronics use as well, so you no longer have to carry multiple cables. Awesome!

The catch, however, is that only the 15 Pro uses this port for faster USB 3 transfer speeds of up to 10Gbps, while the vanilla iPhone 15 is still limited to USB 2 speeds (0.5Gbps). Now, this is not issue if you don't have to transfer files via a cable very often, which is probably why the feature has been made a Pro-model exclusive.

That being said, even if you buy the Pro model, you will have to separately purchase a USB 3 compatible cable to benefit from the faster speeds as the cable that comes in the iPhone 15 Pro box does not support USB 3 transfer rates.

Thankfully, you don't need an Apple-branded cable for that. Any USB 3 cable will do — we tested the USB 3 transfer speeds of the iPhone 15 Pro here, where we confirmed the transfer speeds Apple claims its new Pro iPhones can achieve, and concluded that uploading to the cloud was no longer the only option for transferring files from your iPhone!

And finally on the design front, both phones have identical IP68 water and dust certification, just in case you were wondering.

Next up, the screens. Both use a 6.1" OLED panel and while resolution and colors are about the same on these two iPhones, one very important feature is missing on the regular iPhone 15 - 120Hz ProMotion! We wonder how long will Apple stick with a 60Hz screen on the regular models, but while we don't know the answer to that we do know that scrolling still feels a bit choppy on the iPhone 15 compared to the smoothness on the 15 Pro.

That being said, if you have only been using phones that have a 60Hz refresh rate (which is most likely the case if you are coming from an older iPhone, especially a non-Pro one, then you won't even address this as a problem. Then again, once you go 120Hz you can hardly go back, and you will definitely not regret it as it improves the whole experience of using your phone.

Our display benchmark tests show that both the iPhone 15 and the 15 Pro are now much brighter compared to their predecessors, and hit roughly the same peak brightness levels between each other.

It's great to see even the less expensive iPhone 15 model get that brighter display for a more comfortable outdoor viewing experience. One thing, however, which we wish was better is the minimum brightness. It remains at around 2 nits, which is not quite as dim as other rival phones can get, and you may notice this if you use your phone at night in bed.

And when it comes to biometrics, there is no difference: both phones use Face ID, which works great.

The iPhone 15 Pro has the new A17 Pro chip, while the iPhone 15 uses the previous-gen A16 Bionic.

The new A17 SoC is a generational leap forward. Chips improve every year, but we rarely have a transition to a new manufacturing process and that is exactly what we have with the A17 Pro. It's the first smartphone SoC to be manufactured on a 3nm process, so there are more transistors, more power and better efficiency in the same die size.

Is the new A17 Pro chip alone a reason for upgrade? Probably not, as both the A17 and A16 are plenty fast, but it adds more headroom and bragging rights for the Pro owners.

According to the benchmark tests that we conducted, the iPhone 15 Pro is the clear winner here with significantly better performance than the iPhone 15, as one could imagine. Gamers will also be excited to know that the A17 Pro comes with hardware-accelerated ray-tracing, and that major game titles like Assassin's Creed: Mirage and Resident Evil 4 Remake are coming to the iPhone 15 Pro and iPhone 15 Pro Max.

Now, while the A17 Pro does wow us with great performance bursts, it does throttle effortlessly — Apple had some issues with thermal management early in the iPhone 15 Pro's life but subsequent iOS 17 updates tuned the performance curve a bit. Stress tests show this to be drastic, but our daily use still feels fast, snappy, and confident.

We expected a more stark difference in our benchmark performance tests, so it is a bit surprising to see that the iPhone 15 Pro is not that much faster than the standard iPhone 15 in processing power. The main advantage is most visible in the graphics department, where the Pro outshined its cheaper counterpart by a significant amount.

The 15 Pro also makes the jump to 8GB RAM, while the iPhone 15 has 6GB. This isn't much of an upgrade and it can be argued that doesn't change much since iOS so often freezes apps in the background (that's one of the keys to good battery life). But modern software does require some background operation, and a minimum of 8 GB of RAM is recommended, if only to give you peace of mind for the next few years.

As for software, both the iPhone 15 Pro and the vanilla iPhone 15 model come with the same iOS 17 platform out of the box. What’s new in this latest version are improvements to the Phone, Messages and FaceTime apps, plus a few other tweaks among which better autocorrect that learns how you like to type (finally!), as well as triggering Siri by just saying “Siri” instead of “Hey Siri”. The new Journal app is coming with iOS 17.2, so you can start writing your memoirs... if that's what you were waiting for.

The changes to the Phone app are most visible. You can now set a Contact Poster for yourself which will be displayed full-screen on other iPhones when you call them, and similarly you will see other people’s posters when they call. NameDrop is another new feature where you just bring your iPhone close to another one to exchange contacts. And in the Messages app, you have new stickers and animated stickers which you can create from your own photos, as well as automatic transcripts of voice messages.

iOS 17 also brings a new Standby Mode, turning your iPhone into a sort of a mini home hub, displaying useful information while it’s charging. Keep in mind, though, that since only the Pro model has an Always-on screen option, the Standby Mode only works properly on that phone and you cannot really benefit much from it on the regular iPhone 15.

Both phones will also receive the new iOS 18 update when Apple starts rolling it out this September or October. The new update will bring much awaited customization options to iOS, like the ability to freely place app icons wherever you want (wow!), or the ability to tint app icons with any color you want with a new Customize Sheet.

Other noteworthy iOS18 features include a redesigned Control Center that users will have fill control over, being able to freely move, remove, and add different settings inside it. The Control Center is also be multi-paged, so you can create different pages with different toggles.

Unfortunately, even though they are from the same generation, only the iPhone 15 Pro will get the new Apple Intelligence and much more powerful Siri, as the standard iPhone 15 does not have enough RAM to support those.

Apple is known for having some of the best software update policy in the industry, and both these phones are expected to be updated for the next five or even six years. Although Google and Samsung have now committed to seven and four years of updates, respectively, they just don't have the track record to prove it yet (the timer hasn't ticked away). Whereas, we have a history of iPhone models getting 5 years of support consistently.

Finally, for connectivity there is no difference between these two as both support 5G bands and both have the cool new Emergency SOS via satellite feature, which might just be a lifesaver in areas with no cellular coverage. Emergency SOS is supposedly going to become a paid subscription in the future, but is now free for a second year in a row.

Camera aficionados know that one of the bigger reasons to choose the  iPhone15 Pro over the vanilla 15 model is that 3X zoom camera which gives it more zoom versatility and helps with Portrait Mode shots.

Of course, there is also the fact that you can shoot in a RAW format with the iPhone 15 Pro, which gives you higher-quality shots with more information, making the editing process so much more powerful. However, if you don't want to tinker too much with your photos, than the big 24MP default photos of the regular 15 will do.

Similarly, you can also record in a log profile with the iPhone 15 Pro, which is somewhat similar to what RAW photos are, but for video. Again, this is a feature that will mostly be appreciated with enthusiasts and professionals that are invested in cinematography and photography.

The regular iPhone 15 this year, however, is getting a big upgrade with a 48-megapixel main camera sensor, which is good news. This will not quite be the same sensor as on the iPhone 14 Pro, but it does support 2X optical-grade zoom (the camera crops into the high-res sensor) and allows for 2X portraits, a very welcome feature.

As for the Pro version, it made the jump to that higher res 48-megapixel sensor last year, and this year, it seems to use the same 48MP sensor. It's worth noting that, even though the resolution is the same, the Pro's sensor and lens are different. Nevertheless, the pictures that come out from both these phones are very, very limilar.

Both phones can also now shoot Super High Res photos at a 24-megapixel resolution. This is a great middle ground between low-detail 12MP shots and high-detail but very large sized 48MP pictures. Great idea, Apple!

Not just this, you get new focal lengths only on the Pro with optical-grade quality: 1.2X (aka 28mm) and 1.5X (aka 35mm). These are great focal lengths that give you a lot more versatility, and are bigger upgrades than you may think initially.

At 2X zoom, the iPhone 15 Pro and iPhone 15 get a very similar amount of detail, but when you go to 3X zoom or further, you really start to notice the difference with cleaner detail on the Pro model.

The maximum zoom level on the iPhone 15 Pro is 15X, while on the regular iPhone 15 you get up to 10X zoom.

Both have a very similar ultra-wide camera, at least when it comes to daytime shots, however, in low light the one on the iPhone 15 Pro captures slightly cleaner shots, but the difference is not huge.

There is not a huge difference in image quality in low light between these two, unless you want to nit-pick

The more noticeable difference is with the ultra-wide camera where you occasionally get a noisier picture on the regular model.

We did not see a difference in video quality: colors, stabilization, detail, everything looks practically identical on the two.

The only area where the 15 Pro has the upper hand is when zooming, and it can go up to 9X zoom compared to just 6X zoom on the regular model.

The 15 Pro can also record ProRes video. This is a feature that only few pro users will use simply because the files sizes are enormous and you need to edit the files to be able to use them, which most people won't bother doing. ProRes video can be color graded and theoretically should have slightly better dynamic range than regular video, but in our view the only real advantage of shooting ProRes is that videos don't have the added sharpening that you get with the default video option, and this alone is a big difference when you view them on a larger screen. But again, this is a niche feature and with those huge file sizes, we doubt it will be of much use to the regular user.

Here's a summarized look of the iPhone 15 Pro vs iPhone 15 cameras, through the lens of our new in-depth camera rating. Each camera has a specific score which contributes to the overall score of the phone's camera system.

If you want to find out more about what we do during our camera tests and how we rate the camera system of each phone you can check out our PhoneArena Camera Score benchmark page.

With a bottom-firing speaker and an amped tweeter in the earpiece, these have a similar hardware, but the iPhone 15 Pro model sounds a tiny bit better: the regular iPhone 15 has a bit less "punch", and highs are just a bit less clean compared to the 15 Pro. It's not a huge difference by any means, but we did it notice it when listening closely.

Neither of these has a headphone jack, as expected, and let us also remind you that you can use the new USB-C port to connect wired headphones with USB C.

No differences in the haptics department too. Both phones come with the Taptic Engine that Apple has been using for years and it has excellent response time and clicky feel.

The iPhone 15 Pro actually comes with a slightly smaller battery size than the regular iPhone 15 model. We guess that difference is explained by the larger camera system on the Pro version which takes up more space.

You get a 3,274 mAh battery on the iPhone 15 Pro and a 3,349 mAh battery on the iPhone 15, but despite that small difference, Apple official estimates say battery life on the iPhone 15 Pro is a bit better than the regular iPhone 15 when it comes to video streaming. The regular iPhone 15 however lasts a bit longer for audio playback.

Below, you can find the official Apple battery life estimates:

 

If you don't want to hear just Apple's version, however, we also have our own battery tests, so here are the results we got here in the office when we tested the iPhone 15 and 15 Pro on our end.

As you can see, the iPhone 15 Pro scores higher in our web browsing test, while the iPhone 15 outlasts it in our YouTube video streaming test. We always conduct our battery tests with the displays set at 200 nits of brightness in order to get an even playing field for all devices. 

In real life, we found that you can expect around 6 hours of screen time on an average day on both phones, which should get you through to the evening, but not much more.

Speaking of charging, know that you don't get a charger in the box, but only a USB-C charging cable (a braided one for better durability).

Unfortunately, charging speeds have not improved, and it would still take you around 1 hour and 40 minutes to charge these iPhones from zero to full.

One thing that has improved are transfer rates, but only on the 15 Pro model which now supports USB 3 at speeds of 10Gbps. With a caveat, though! The provided cable in the box won't give you those faster speeds, you need to purchase a thicker cable for that and that will cause you extra.

Thanks to the 15W MagSafe support, we didn't find the slow-ish charging via cable to be too much of an issue — a MagSafe charger on your work desk or in the car ensures that the iPhone gets extra percentages while not in use.

And here is an overview of the specs differences between the Pro and non-Pro models:

Also, check out our in-depth iPhone 15 Pro vs iPhone 15 specs comparison where we provide more information about every individual hardware component.

At the end of the day, the iPhone 15 Pro and iPhone 15 are more similar than different, which makes the choice between the two very tough.

As for the Pro model, we like that Apple has addressed our the biggest concern with the reduction in weight.

The iPhone 15 Pro main advantages remain the 120Hz ProMotion for smooth scrolling, as well as the 3X zoom camera, and that new Action button is a nice little convenience (but nothing more).

However, the iPhone 15 is indeed very similar. It can look a bit choppy sometimes because it lacks 120Hz technology, but the processor is fast and unless you want to zoom far away, you probably won't notice a difference in the camera quality at all.

Honestly, we have a really hard time choosing between the two, but if there ever was a time to save $200 and get the non-Pro model, it's this year.
