My iPhone 15 Pro Experience After a Month: These Phones Are Performance Beasts
Commentary: Remarkable CPU and battery test scores show the power of the iPhone 15 Pro and Pro Max. Plus, get the whole scoop on overheating.

The iPhone 15 Pro and Pro Max are defined by their refinements and represent one of the most compelling Apple releases in years. When I initially reviewed both phones, I was impressed with the lighter build, new shortcut button, cameras and the A17 Pro chip. Like the regular iPhone 15, the Pro models have a USB-C charging port instead of Apple’s proprietary Lightning connector, making charging more convenient.
But a lot has happened over the past month. Widespread reports of phones overheating made for a somewhat controversial launch, but Apple has since addressed the issue.
Over the past four weeks, I further tested the iPhone 15 Pro’s cameras, ran CNET’s battery drain test, evaluated performance and conducted charging tests. And I had more time to use the iPhone 15 Pro as my everyday smartphone. Here are my findings.
iPhone 15 Pro-gate(s)
Since the iPhone 15 Pro launched, there have been a few controversies including reports of the iPhone 15 Pro easily bending or experiencing screen burn-in. I have not encountered any of these issues, nor have my CNET colleagues. According to MacRumors, the beta version of iOS 17.1 alleviates the burn-in problem, and the final version, which just came out this week, could do the same. It’s difficult to judge how widespread the burn-in issue is based on these reports alone.
Then there was FineWoven case-gate. Apple announced it would no longer continue to make its own line of leather cases and accessories to help reduce its impact on the environment. As a replacement, Apple launched a new line of FineWoven cases that aren’t made from animal products.

While the cases protected my 15 Pro and Pro Max just fine, the FineWoven cases showed wear and tear after just a week. Dirt and scuffs easily remain; the case on my 15 Pro had scuff marks and indents despite not having used it much the first week. The case’s MagSafe magnet left a circular imprint on the cases for my 15 Pro and Pro Max.
Apple’s support page on taking care of FineWoven cases and accessories includes instructions on how to clean them. I tried this on one of my FineWoven cases, and it got most of the dirt out. But I don’t want a phone case that I have to clean every couple of weeks.
I carry my iPhone 15 Pro Max without a case and use Peak Design’s slim wallet, which is also fabric, but I can touch it without worrying about scuffs. The wallet works with Peak Design’s cases or MagSafe to magnetically attach to the back of my phone. After three weeks of use, the Peak Design slim wallet still looks new, surviving harrowing hours next to keys in my pocket.

Perhaps the biggest iPhone 15 scandal involved reports of phones overheating. Apple told CNET that there were four causes that made an iPhone feel warmer than normal, none of which were specifically tied to Pro models, their titanium design or the iPhone 15 series specifically.
When you use a power adapter higher than 20 watts, the phone can feel warm to the touch. This holds true if you’re using a Lightning cable on the iPhone 14 series or a USB-C cable on the iPhone 15 series. I used my MacBook Pro’s 140-watt charger over USB-C to charge the 15 Pro and noticed it was warm to the touch after 30 minutes.

According to Apple’s support page, restoring from a backup file or setting up a new phone from scratch can also cause the iPhone to get warmer than normal, as can playing graphic intensive games. When I played Resident Evil Village on the iPhone 15 Pro, it was noticeably warm after 30 minutes.
Certain apps like Instagram and Uber as well as bugs in iOS 17 caused iPhones old and new to overheat. Apple worked with app developers to fix the problem (both Instagram and Uber have updated app versions) and released the iOS 17.0.3 update to solve the issue.

iPhone 15 Pro and Pro Max charging tests
One of the biggest changes to the iPhone 15 series was the inclusion of a USB-C port instead of Lightning. Despite the change, charging speeds are identical to iPhone 14 series models.
I ran several charging tests on the iPhone 15 Pro and Pro Max. I used a 20-watt charger for the first test and noted how the battery percentage increased after 30 minutes. As you can see in the chart below, both the 15 Pro and Pro Max recharged more of their respective batteries than the iPhone 14 Pro and Pro Max.
30-minute charging test (20W adapter)
Starting percentage | Ending percentage | Percentage added | |
---|---|---|---|
iPhone 15 Pro | 4% | 66% | 62% |
iPhone 15 Pro Max | 7% | 56% | 49% |
iPhone 14 Pro | 27% | 75% | 48% |
iPhone 14 Pro Max | 14% | 59% | 45% |
The iPhone caps its max charge speed to 27 watts, so using a power brick that supports a higher wattage won’t make the phone charge any faster. So I ran the same test a couple of more times, using my MacBook Pro’s 140-watt charger. I ran it before and after installing iOS 17.0.3, and the charging speeds were identical. That means the software fix doesn’t throttle charging speeds. Results were nearly the same as those from my 20-watt charging test.
30-minute charging test (140W adapter)
Starting percentage | Ending percentage | Percentage added | |
---|---|---|---|
iPhone 15 Pro before iOS 17.0.3 | 0% | 63% | 63% |
iPhone 15 Pro after iOS 17.0.3 | 0% | 62% | 62% |
iPhone 15 Pro Max before iOS 17.0.3 | 18% | 67% | 49% |
iPhone 15 Pro Max after iOS 17.0.3 | 17% | 67% | 50% |
I ran a 30-minute wireless charging test via MagSafe on both phones, and the results were almost exactly the same. The 15 Pro added 22% over a half hour period, and the 15 Pro Max added 21%.
iPhone 15 Pro and Pro Max battery tests
In my experience, the 15 Pro averages a full day on a single charge, while the 15 Pro Max gets between a day and a half to two days. Battery life can vary depending on how you use your phone, so I also ran two additional CNET battery tests.
The first was an endurance test. Over the course of 45 minutes, I played games, watched YouTube videos, made a FaceTime video call, and scrolled my Instagram and TikTok feeds. As you can see in the results below, both new Pro models did better than the iPhone 14 Pro and Pro Max, as well as Samsung’s Galaxy S23 series. The less battery percentage lost, the better.
45-minute battery endurance test
Starting percentage | Ending percentage | Percentage lost | |
---|---|---|---|
iPhone 15 Pro Max | 100% | 97% | 3% |
iPhone 15 Pro | 100% | 94% | 6% |
Galaxy S23 Ultra | 100% | 94% | 6% |
iPhone 14 Pro Max | 75% | 68% | 7% |
iPhone 14 Pro | 87% | 79% | 8% |
The second test I ran involves streaming a video over the course of three hours with the battery starting at 100%. I checked the battery level at every hour to see how much the battery percentage dropped. The results show that the 15 Pro and 15 Pro Max last longer than the Galaxy S23 Ultra did in the same test. The less battery percentage lost, the better.
3-hour video streaming test
After 1 hour | After 2 hours | After 3 hours | |
---|---|---|---|
iPhone 15 Pro Max | 97% | 92% | 87% |
iPhone 15 Pro | 98% | 92% | 86% |
Galaxy S23 Ultra | 95% | 89% | 82% |

iPhone 15 Pro and Pro Max performance tests
The iPhone 15 Pro and Pro Max have the A17 Pro chip, meaning they can support console video games. I was blown away when I played Resident Evil Village on my iPhone 15 Pro Max. The only sign that the phone was working hard was that the back of the device felt warm after 30 minutes.
I also ran several performance benchmark tests to see just how powerful Apple’s new A17 Pro chip is. I ran the Geekbench 6 CPU test, which measures general performance, and 3D Mark Wild Life Extreme for testing graphics performance.
As you can see in these results below, the A17 Pro chip enabled the iPhone 15 Pro and Pro Max to score higher than any phone we’ve ever tested. They not only outperformed the iPhone 14 Pro Max but every Android phone we’ve tested this year, including the Galaxy S23 Ultra. All of the 15 Pro and Pro Max’s power is kind of overkill now, but should help their longevity as new features and versions of iOS come out.
Geekbench v.6.0 single-core
Geekbench v.6.0 multicore
In terms of graphics, the 15 Pro and Pro Max’s performance is on par with the Samsung Galaxy S23 series, which runs on the Snapdragon 8 Gen 2 for Galaxy chip.
3DMark Wild Life Extreme

Other iPhone 15 Pro and Pro Max standout features
After spending one month with the iPhone 15 Pro and Pro Max, a few features stood out to me. At the top of that list is the 15 Pro Max’s 5x optical zoom. It captures beautiful images with great detail and a wide dynamic range. Check out the photo above that I took of the Manhattan Bridge just after sunrise.
I’m also impressed with the new 24-megapixel resolution option. It basically combines pixel binning image data and resolution image data into a single higher resolution photo that has more detail than photos taken on the 14 Pro or Pro Max.
As I mentioned before, I don’t use a case on the phones and love the way they feel in my hand. Apple found a good balance between the weight and the size of the phone, especially the 15 Pro Max model. The slightly curved edges make the phones enjoyable to hold.
Apple’s iOS 17 software has been a blast to use, especially Check-In and Stickers in iMessage. I get so much joy from turning live photos into animated stickers and peppering them in message threads to the delight and annoyance of my friends.

StandBy mode is also nice and turns the 15 Pro and Pro Max into a mini heads up display for time, photos and other widgets when charging. I use a Belkin BoostCharge Pro dock for StandBy mode at work and a Twelve South HiRise 3 Deluxe dock at home. The StandBy screen looks contemporary, and I like being able to switch between the widgets. I do hope Apple adds more functionality to StandBy mode in iOS 18.
But there are some software bugs in iOS 17. For example, I had Safari freeze and become unresponsive when trying to navigate or reordering tabs. These hang-ups only happened a few times and don’t seem too problematic, but they are annoying.
My CNET colleague Bridget Carey experienced a weird bug in which black borders appeared to the right and underneath photos she took. She said quitting the Camera app and reopening it resolved the issue, even though the pictures she took before the app reset still show up in the Photos app with black borders. There is a MacRumors forum post showing someone else experiencing the same thing.
What’s next for the iPhone 15 Pro and Pro Max? Well, we’re still waiting for Apple to add the ability to record 3D videos (Apple calls them spatial videos), which you’ll be able to watch in 3D on the new Vision Pro headset. The Journal app in iOS 17 still hasn’t launched, though it does appear in the beta version of iOS 17.2. Apple didn’t say exactly when the new app would be released, but I’m keen to try it out. The app uses AI prompts to get you started writing.
After a month with the iPhone 15 Pro and Pro Max, I’m still enamored. And I’m excited to continue testing them for months to come.

Blade Runner: 18-Rotor «Volocopter» Moving from Concept to Prototype
It may look "nutty" and like a "blender," but the designers say the craft could challenge helicopters
Inventor and physicist Thomas Senkel created an Internet sensation with the October 2011 video of his maiden—and only—test flight of a spidery proof-of-concept 16-rotor helicopter dubbed Multicopter 1. Now the maker of the experimental personal aviation craft, the European start-up e-volo, is back with a revised «volocopter» design that adds two more rotors, a serial hybrid drive and long-term plans for going to 100 percent battery power.
The new design calls for 1.8-meter, 0.5-kilogram carbon-fiber blades, each paired with a motor. They are arrayed around a hub in two concentric circles over a boxy one- or two-person cockpit.
After awarding the volocopter concept a Lindbergh Prize for Innovation in April, Yolanka Wulff, executive director of The Charles A. and Anne Morrow Lindbergh Foundation, admitted the idea of the multi-blade chopper at first seems «nutty.» Looking beyond the novel appearance, however, she says, e-volo’s concept excels in safety, energy efficiency and simplicity, which were the bases of the prize.
All three attributes arrive thanks largely to evolo’s removal of classic helicopter elements. First, the energy-robbing high-mass main rotor, transmission, tail boom and tail rotor are gone. The enormous blades over a normal chopper’s cabin create lift, but their mass creates a high degree of stress and wear on the craft. And the small tail rotor, perched vertically out on a boom behind the cabin, keeps the helicopter’s body from spinning in the opposite direction as the main blades, but it also eats up about 30 percent of a helicopter’s power.
The volocopter’s multiple rotor blades individually would not create the torque that a single large rotor produces, and they offer redundancy for safety. Hypothetically, the volocopter could fly with a few as 12 functioning rotors, as long as those rotors were not all clustered together on one side, says Senkel, the aircraft’s co-inventor and e-volo’s lead construction engineer.
Without the iconic two-prop configuration, the craft would be lighter, making it more fuel efficient and reducing the physical complexity of delivering power to the top and rear blades from a single engine. Nor would the volocopter need an energy-hungry transmission. In fact, «there will be no mechanical connection between the gas engine and the blades,» Senkel says. That means fewer points of energy loss and more redundancy for safety.
E-volo’s design eliminates the dependence on a single source of power to the blades. As a serial-hybrid vehicle, the volocopter would have a gas-fueled engine, in this case an engine capable of generating 50- to 75 kilowatts, typical of ultralight aircraft. Rather than mechanically drive the rotors, the engine would generate power for electric motors as well as charge onboard lithium batteries. Should it fail, the batteries are expected to provide enough backup power so the craft could make a controlled landing.
Whereas helicopters navigate by changing the pitch of the main and tail rotor blades, the volocopter’s maneuverability will depend on changing the speed of individual rotors. Although more complex, it is more precise in principle to control a craft using three to six redundant microcontrollers (in case one or more fails) interpreting instructions from a pilot using a game console–like joystick—instead of rudder pedals, a control stick and a throttle.
Wulff’s first impression about the volocopter’s design is not uncommon. E-volo’s computer-animated promotional videos of a gleaming white, carbon-fiber and fiberglass craft beneath a thatch of blades recall the many-winged would-be flying machines of the late 19th century. This point is not lost on Senkel.
«I understand these skeptical opinions,» he says. «The design concept looks like a blender. But we really are making a safe flying machine.»
That would be progress in itself. Multicopter 1 looked like something from an especially iffy episode of MacGyver, complete with landing gear that involved a silver yoga ball. Senkel rode seated amid all those rotors powered only by lithium batteries. Multicopter 1 generated an average of 20 kilowatts for hovering and was aloft for just a few minutes.
There’s a reason why the experimental craft flew briefly and only once.Senkel describes that first craft as «glued and screwed together.» Seated on the same platform as the spinning blades, he says, «I was aware of the fact that I will be dead, maybe. Besides, we showed that the concept works. What do we win if we fly it twice?» he asks rhetorically.
Other than putting the pilot safely below the blades, the revised volocopter design would operate largely the same as the initial prototype. The design calls for three to six redundant accelerometers and gyroscopes to measure the volocopter’s position and orientation, creating a feedback loop that gives the craft stability and makes it easier to fly, Senkel says.
The volocopter’s revised prototype under construction could debut as soon as next spring. The first production models, available in perhaps three years, are expected to fly for at least an hour at speeds exceeding 100 kilometers per hour and a minimum altitude of about 2,000 meters, still far shy of standard helicopter’s normal operating altitude of about 3,000 meters. «This could change our lives, but I don’t expect anything like that for 10 years,» Senkel adds.
Given that most of the technology needed to build the volocopter is already available, «this idea is fairly easy to realize,» says Carl Kühn, managing director of e-volo partner Smoto GmbH, a company that integrates electric drive systems and related components.
Like Senkel, Kühn has modest short-term expectations despite his repeated emphasis on the standard nature of the technology involved. «I guess that e-volo will have [a prototype] aircraft in three years that can do the job—that it will lift one or two persons from one point to another,» he says.
The biggest immediate limitations appear to be regulatory. For instance, European aviation regulators consider any electrical system greater than 60 volts to be high voltage and regulate such systems more aggressively, Kühn says. As a result, the volocopter will operate below that threshold. The craft will also need to weigh no more than 450 kilograms to remain in the ultralight category, which is likewise subject to fewer government aviation regulations, according to Senkel.
The Lindbergh Foundation’s Wulff says the organization’s judges felt e-volo had «a greater than 50 percent chance of succeeding, or they wouldn’t have given them the innovation award.» Asked if she would line up to fly one someday, she says, «I sure would. It looks very compelling to me.»
