iPhone 17 vs. iPhone Air Battery Test Showdown: I Just Crowned A New Winner

I’ve got exclusive CNET data for three years of iPhone models. See how the latest phones rank historically.

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.

I’ve been reviewing smartphones at CNET for nearly a decade. If there’s one feature people consistently want in a new iPhone or Android phone, it’s longer battery life.

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.

Artemis II Astronauts Name Moon Crater After Commander Reid Wiseman’s Late Wife

The emotional moment was streamed by NASA moments after the crew made history.

On Monday, after the crew aboard Artemis II made a historic feat by breaking Apollo 13’s distance record, they made the moment even more special by proposing to name one of the craters on the moon «Carroll,» in memory of Commander Reid Wiseman’s late wife.

While contacting Mission Control, Mission Specialist and astronaut Jeremy Hansen stated that the «close-knit astronaut family» previously lost a loved one who was «the spouse of Reid, the mother of Katie and Ellie.»

«It’s a bright spot on the moon,» Hansen said while describing the crater during the emotional call. «And we would like to call it Carroll.»

After the request, you can see Wiseman embrace Hansen before the rest of the crew joins in for a group hug.

Carroll Wiseman died in 2020 at 46 years old from cancer. Wiseman’s NASA bio page states that Carroll «dedicated her life to helping others as a newborn intensive care unit Registered Nurse.»

Before the Artemis II mission, Wiseman posted a selfie with his two daughters on X with a caption that reads in part, «I love these two ladies, and I’m boarding that rocket a very proud father.»

Artemis II Astronauts Are Using iPhones to Capture Stunning Space Images

After smartphones were cleared by NASA for space missions, the crew members of the Integrity spacecraft are beaming back lots of iPhone photos.

The four astronauts aboard the Integrity spacecraft now headed home from their historic arc around the moon really are like the rest of us: Sometimes they reach for their smartphones to snap photos.

For the Artemis II mission, iPhone 17 Pro Max phones have been used to capture photos inside the capsule of the astronauts pondering the views of Earth and working on mission objectives. (Technically, NASA refers to them as PCDs – personal computing devices.)

Smartphones were cleared for use in space for the first time in February. In a post on X, NASA Administrator Jared Isaacman wrote, «We are giving our crews the tools to capture special moments for their families and share inspiring images and video with the world.»

Early in the mission, Commander Reid Wiseman snapped a pair of photos looking out the window with Earth behind him. Mission specialist Christina Koch and her dynamic curls in zero-gravity also captured a pensive view looking out over the planet. All three were made using the front camera — because wouldn’t you want to grab a selfie if you were in space?

The iPhone 17 Pro’s rear cameras are pulling their own weight during the mission, too. During the live broadcast as the crew approached the moon, Wiseman took a photo of the moon’s surface using the iPhone’s telephoto camera at 8x zoom. He turned the screen toward one of the video cameras mounted inside the spacecraft, creating an image of the moon’s surface alone against the darkness of the unlit cabin, with the iPhone’s signature rounded edges and Dynamic Island cutout at the top.

The main photo workhorses on this trip are a Nikon D5 DSLR and a Nikon Z9. The D5 is a model that has been used on several space excursions, and the Z9 is onboard as an experimental camera.

For NASA missions, every piece of equipment must be tested and certified, which is why the previously-approved D5 has a secure spot. Cameras must be resistent to space environmental factors like radiation, and safe if they’re floating around the capsule. However, the iPhones in space now are off-the-shelf models, according to a report by Jackie Watties of CNN.

The moon flyby was especially photo-intensive, with astronauts switching places several times so that two were always at windows with cameras and relating what they could see with their eyes. This photo of mission specialist and Canadian Space Agency astronaut Jeremy Hansen taking images using one of the Nikon cameras shows how some windows have camera shrouds attached. The shroud ensures that light from the interior isn’t reflected in the glass.

In a particularly relatable photo, Hansen is also using the front-facing camera of a white iPhone 17 Pro — as a portable mirror while he shaves. As the (modified) saying goes, the best selfie screen is the one you have with you.

The iPhone 17 Pro isn’t the first Apple product to go into space. Crew members have taken iPods, iPads and AirPods on missions since the Space Shuttle era. The Mac Portable even went up on a shuttle (and revealed that its trackball in zero-G isn’t the best option).

An Apple representative didn’t immediately respond to a request for comment.
