Which 2025 iPhone Has the Best Battery? I’ve Crowned a New Power Winner

I looked at three years of exclusive CNET data of iPhone performance to find out which models hold their charges best.

Key takeaways:

  • The iPhone 17 Pro Max has outstanding battery life that easily lasts all day with charge to spare.
  • Our exclusive lab data shows you don’t need to pay over a grand for excellent battery life. The $829 iPhone 17’s battery lasts just as long as the $1,099 iPhone 17 Pro.
  • The ultrathin iPhone Air, with a modest battery capacity, outlasted Samsung’s premium Galaxy S25 phones.

You might say that battery life is just a small consideration when buying a new iPhone or Android phone now, but that stance gets shaky when you’re staring down a sliver of red in the battery gauge and have nowhere to plug in. After reviewing smartphones for over a decade, I’ve learned that longer battery life is the one feature people consistently want from their phones.

When Apple launched the new iPhone 17 series and iPhone Air, it spent considerable time touting the longer battery life of the iPhone 17, 17 Pro, and 17 Pro Max, as compared to their predecessors. 

My fellow CNET reviewers and I have now had the chance to test those claims.

When introducing the iPhone Air and its super slim design, Apple showed a slide during its keynote stating that it has all-day battery life. However, the company undercut its claim on the next slide when it announced a new MagSafe battery pack designed for the Air, which fed into fears that a thinner design might indicate a significant sacrifice to battery life.

Your phone’s battery life is affected by multiple variables, like how bright you keep your display or if your phone has a weak signal from your carrier. How you use your phone has a big impact, too. Someone who is obsessively online will have a much different experience with their battery life than someone who has their phone in their bag at work and checks it on breaks.

So, how do you know whether the battery life is good on the iPhone Air and iPhone 17 series?

CNET tested the new Apple phones’ battery life three ways: through an anecdotal stress test, a video streaming test and observing battery life after everyday use. We also tested wired and wireless charging. Our lab data showed strong battery life for the iPhone 17, 17 Pro, 17 Pro Max and even the Air, especially compared to older iPhone models.

The iPhone 17 Pro Max has excellent battery life

Bigger batteries don’t always mean superior battery life. There’s more to battery life than the physical size or capacity. Besides Huawei, Apple is the only major smartphone maker that builds its own hardware and software and can tune its phones to work off smaller batteries than most Android phones have. 

The iPhone 17 Pro and 17 Pro Max have larger batteries than last year’s 16 Pro and 16 Pro Max. If you’re using an eSIM-only version of either phone, like the iPhone models sold in the US, your battery is even bigger because it takes up the space where the SIM card tray would be.

Frustratingly, Apple doesn’t share the capacity of the iPhone’s batteries, and part of the reason is that its batteries are often smaller than those in Android phones. Fortunately, the EU requires that Apple publish energy labels that include the capacity of its batteries on its site. Macrumors found the capacities for eSIM-only models. You can see how the new phones’ batteries compare to the ones in the iPhone 16 series:

  • iPhone Air: 3,149 mAh
  • iPhone 17: 3,692 mAh
  • iPhone 17 Pro: 4,252 mAh
  • iPhone 17 Pro Max: 5,088 mAh
  • iPhone 16: 3,561 mAh
  • iPhone 16 Plus: 4,674 mAh
  • iPhone 16 Pro: 3,582 mAh
  • iPhone 16 Pro Max: 4,685 mAh

CNET has two benchmark tests (video streaming and stress tests) that allow us to compare the battery performance of one phone against another. And because we’ve been using these tests for years, we can also compare a new phone against older models. 

For example, if you have an iPhone 15 and are considering upgrading to an iPhone 17, we can tell you that the new iPhone will have a longer battery life out of the box than your old one.

In CNET’s 3-hour video battery test, where we streamed a video over Wi-Fi with the screen at full brightness, the iPhone 17 series did terrific, even if the results were not dramatically better than the iPhone 16 series.

Without a Plus model this year, the iPhone 17 Pro Max is the only model with a big battery (the biggest one ever in an iPhone), and it only lost 9% in the test. The lower the percentage lost, the better. This is the first time an iPhone stayed in single digits, and I should note that the 17 Pro Max tied the Motorola Razr (2024) for the best score since we’ve been running the test. The Razr has a less powerful processor and a smaller main screen with a lower resolution and less brightness.

The iPhone Air and 17 Pro dropped 15% in the test, the same as the iPhone 15. And the iPhone 17 lost only 11%, better than the iPhone 15 and 16.

Something to keep in mind is that the iPhone 17 has a 6.3-inch screen that supports a 1-120Hz variable refresh rate and a max brightness of 3,000 nits, compared to the iPhone 15 and 16, which have a 6.1-inch display with a 60Hz refresh rate and a max brightness of 2,000 nits.

The new Apple phones did well in CNET’s 45-minute endurance test, during which I played games, streamed videos, scrolled social media and took a video call. The 17 Pro Max only dropped a single percent, the best result this year, but behind the iPhone 16 Plus, which stayed at 100% (the best result for any phone).

The iPhone 17 and 17 Pro had the same result, dropping 2%, making the standard iPhone 17 look even more like an incredible value. The iPhone Air dropped 5%, which matches the iPhone 15 in the same test. For perspective, the Air did better in this test than the Samsung Galaxy S25 series and tied with the Motorola Razr Ultra.

The iPhone Air gets through a day

When we review phones, we set them up as our daily driver to use and test them like our personal phones. Real-world testing is often the best indicator of what a reader can expect to get from a phone.

I started each day with a full battery for the iPhone 17 Pro and 17 Pro Max and tracked how much battery I had throughout the day. I ended each day with plenty of battery left — even after shooting photos and videos or keeping the screen at full brightness while filming the review video. Below is a chart that shows how the iPhone 17 Pro Max’s battery performed for the first five days I had it.

Similarly, CNET senior technology reporter Abrar Al-Heeti highlights that the iPhone Air she reviewed regularly ends the day with about 20% to spare (after starting with a full battery). She said it would drop below 20% on heavier-use days by the time she was ready for bed.

«Impressively, the iPhone Air has consistently lasted all day over the last several weeks I’ve been using it,» Al-Heeti said. «But I’ve hardly had to touch that MagSafe battery pack to extend battery life during the day, which is reassuring.»

In our testing, a fully-charged MagSafe battery added 69% to the iPhone Air’s battery. When I asked her whether she’d recommend people buy the $99 MagSafe Battery for the Air, Al-Heeti said that she recommends it for someone who uses their phone often and doesn’t want to hunt for an outlet.

«I don’t like the idea of having to lug around an extra battery, no matter how thin or sleek it is, so I don’t tend to carry it with me unless I know I’m going to have a long day away from home,» Al-Heeti said.

She also reviewed the standard iPhone 17 and said it can easily last a little over a day, even after snapping photos, scrolling through social media, listening to audiobooks and music, texting and watching videos.

Al-Heeti’s review notes that over several days, she’d start with a full battery, between 8:30 and 9:30 a.m., and have 44% to 47% of a charge 12 hours later. If she didn’t recharge the iPhone 17 overnight, she’d still have about 30% to spare the next morning.

The iPhone 17 series charges fast

There are two ways to charge an iPhone: with a cable or with MagSafe (unless it’s the iPhone 16E, which doesn’t have MagSafe, just Qi charging). For wired charging, Apple recommends using a 40W charger with the iPhone 17, 17 Pro and 17 Pro Max and a 20W charger for the iPhone Air. However, Apple doesn’t include a charger in the box, just a USB-C cable, but the company does sell a 40W charger for $39 and a 20W charger for $19.

In our 30-minute wired charging test, the new phones, including the Air, did well. The iPhone 17, 17 Pro and 17 Pro Max added 10% or more than the iPhone 16, 16 Pro and 16 Pro Max in the same test. Apple says the 17 Pro and 17 Pro Max can recharge to 50% in 20 minutes. In our tests, the iPhone 17 Pro hit 53% and the iPhone 17 Pro Max hit 49% after 20 minutes.

The iPhone Air reached 49% in our 30-minute charging test with a 20W adapter, the same as the iPhone 16 and iPhone 15 Pro, beating the iPhone 15 Plus.

In wireless charging or MagSafe charging, we ran a 30-minute test with the latest MagSafe charger and a 30W power adapter. The iPhone 17 series and Air beat every iPhone we’ve ever tested except the iPhone 16 Pro, which did better than the Air and standard iPhone 17. I should note that iPhones don’t come with a MagSafe charger or 30W adapter in the box.

Which iPhone should you buy based on CNET Labs data?

Get the iPhone 17 Pro Max if you want the best battery life. The standard iPhone 17 has great battery life and inches out the more expensive iPhone 17 Pro. And if you’re on Team Air, know that the battery life isn’t great, but depending on how hard you use it, you should get through a day on a single charge.

I should also note that iOS 26 has a new Adaptive Power mode. This feature learns your phone’s use patterns and «adapts» how much power the processor uses for specific tasks, so it draws less from the battery. The new feature takes a week to start working. I turned it on after running CNET’s battery tests and will update this story with any changes or improvements that come from it.

Last, if you have an iPhone and the only issue is that its battery doesn’t charge as much as it used to, think about replacing it with a new one. Doing so will not only be hundreds of dollars cheaper than a new iPhone, but it can extend your phone’s life another couple of years.

The iPhone 17 Pro’s Cameras Take the Fight to the OnePlus 15, and There Are Bruises

Camera showdown: The OnePlus 15’s camera should have surprised me, but it really didn’t. Meanwhile, Apple’s iPhone 17 Pro keeps on delivering in terms of photography.

The OnePlus 15 impressed my excellent colleague, David Lumb, with its superb battery life and excellent performance, especially for gaming. I wasn’t as thrilled with the cameras in my early testing, but the proof of its photography prowess comes down to how it stacks up against the competition. In this case, the iPhone 17 Pro is one of our favorite phone cameras and indeed one of the best camera phones you can buy in 2025

For years, OnePlus has partnered with the iconic Swedish camera maker Hasselblad to work on color science and image calibration for OnePlus phones. But that partnership has ended, which puts a lot of pressure on the Chinese company to impress with its camera suite on the OnePlus 15. Throughout all these changes, Apple released the iPhone 17 Pro, which has a brand-new 48-megapixel 4x telephoto camera and carries forward the company’s reputation for excellent photography.

I headed out to the streets of Edinburgh, Scotland, to test both phone cameras in a variety of situations. It’s important to note, though, that what I consider «better» might not be what you agree with. Photography, like all art, is subjective. While, as aprofessional photographer, I prefer more natural, true-to-life tones, you may prefer imagery with more pop and colors. Take my thoughts with a grain of salt. 

Note, too, that all images were taken with each phone’s standard camera mode in JPEG format, and all images have been resized using Adobe Lightroom, with no additional edits or sharpening applied. Small print done with, let’s dive in.

Straight off the bat, I’ll admit a small mistake in the photos above. I took this shot using one of the iPhone’s Photographic Styles. I think it was Gold, and so it’s no surprise that it’s given the image a more vibrant, warmer look that suits the scene incredibly well. I only had the style active for this example and the ultrawide version below. 

However, I noticed that the iPhone’s exposure is broadly better, while the OnePlus’ software processing had worked so hard in reducing image noise that a lot of the texture in the floor had been lost. 

Switch to the ultrawide lenses, and things do change a bit. The iPhone’s exposure above looks preferable to my eye, but the OnePlus’ shot definitely has more detail overall.

This example above is quite classic of the problems I have not just with the OnePlus 15, but also with most of OnePlus’ phones. The image is quite heavily saturated, with an electric-blue sky and vivid greens that look unnatural to me. The iPhone’s image has a much better handle on color here.

My other problem with OnePlus’ phones is how hard they go with their HDR processing, brightening up shadows and pulling back highlights, resulting in images that quite often lack depth and believable contrast. The image above is a prime example where the deep shadows under this bridge have been maintained in the iPhone’s shot, but where the OnePlus 15 has tried to lighten them so much that the image looks very overprocessed.

And to prove it’s not a one-off, this example above is a real low point for the OnePlus. It really tried to eliminate any kind of shadows in this scene, while pulling back the highlights in the sky outside far too much. The image looks fake, overprocessed and exactly what people would think of if you told them a photo was taken on a phone. By taking a far more subtle approach, the iPhone’s image is much more to my liking. 

The OnePlus hasn’t gone as hard with its vendetta against shadows in the image above, but it does look like it’s ramped that saturation way up. It’s not that I don’t like vibrant colors — I do — it’s just that I want to add in that saturation should I want to, rather than having it forced on me by default. 

The images above show a more muted scene and a good effort from both phones. Although taken just nine seconds apart (I checked the metadata), I do think the sun may have slightly peeked out from behind a cloud a little more in the iPhone’s shot, as the front of the building does look quite a lot brighter. Or maybe the OnePlus is going hard on the HDR again. Who knows? Either way, good details on this image from both phones. 

The same scene in ultrawide does arguably look a little muted from the iPhone, at least when compared with the bold blue of the OnePlus’ shot above. Somewhere between the two would be my sweet spot. After I zoomed in on the details, the iPhone’s shot is certainly clearer, but at full screen — or on your Insta feed — that difference is negligible. 

That brightness and color difference persists when taking each phone to its maximum default telephoto zoom, so maybe it doesn’t have anything to do with the sun and clouds after all. Colors aside, the iPhone’s shot above is also clearer, and its details look sharp without being overly digitally sharpened. The OnePlus’ image does have something of a «crunchiness» to it from its software processing that I don’t like as much. 

Peeping close up at the pixels on each phone’s telephoto zoom shot, I definitely think the OnePlus has gone too hard with its sharpening in the image above of a person in a window.

I’m slightly more torn on this nighttime scene. The OnePlus shot above has yet again gone big on the saturation. Look at the overcooked green on the grass — it looks like it was taken at midday in the spring. The iPhone’s colors look way more natural. However, the OnePlus’ sharpening works in favor at night, delivering a shot with crisper details throughout.

And in ultrawide, I flat out prefer the OnePlus image above. Those vibrant tones look much better here, especially as they make the oranges of the building in the background stand out more.

And if we peep at those pixels again, it’s clear that the details on the OnePlus’ shot (left) are far better. Finally, a win for the OnePlus. 

This final indoor low-light scene is a bit more of a mixed bag. The OnePlus’ image above is unquestionably brighter — especially the people nearest the camera — but its noise reduction has gone a bit too hard in some areas, reducing textures on clothing and hair that the iPhone hasn’t done. Overall, though, I’d say this example is a close fight. 

iPhone 17 Pro vs. OnePlus 15: Which camera is better?

For me, it’s an easy victory for the iPhone 17 Pro. Almost across the board, its images are more natural looking with realistic colors, saturation levels and exposure. The OnePlus 15’s reliance on heavy-handed image processing has resulted in often garish-looking photos that are almost the opposite of what I look for in my photography. However, as I said at the beginning, that’s just my opinion. 

As a photographer, I want my camera — any camera — to be able to capture the best-looking image straight out of the camera that I can then apply more edits to if I want to. But maybe you don’t want to do that and instead want a vibrant, punchy-looking shot that you can immediately share to social media. If so, maybe the OnePlus will be fine for you. 

At the end of the day, deciding which phone to buy will come down to more than just the camera, so make sure to read CNET’s in-depth reviews of all of 2025’s best phones to decide which is the one for you.
