Key TechWege:
- The iPhone 17 Pro Max has outstanding battery life that lasts all day long to save the day.
- Our exclusive lab data shows that you don’t need to pay on Grand for great battery life. The battery of the $ 829 iPhone 17 is just as long as 1,099 iPhone 17 Pro.
- Ultrathin iPhone Air Samsung’s Premium Galaxy S25 with a modest battery capacity has surpassed the phone.
I’ve been reviewing smartphones on CNET for almost a decade. If the new iPhone or Android phones have a consistent feature that people have consistently, this is a long battery life.
When Apple launched the new iPhone 17 series and iPhone Air, it spent a lot of time for the iPhone 17, 17 Pro and 17 Pro Max’s long battery life compared to their predecessors.
My fellow CNET reviewers and I have now had the opportunity to test these claims.
While introducing the iPhone Air and its super slim design, Apple showed a slide during its keynote that it has a battery life. However, the company undercut its claim on the next slide when it announced a new Magsaf battery pack designed for the wind, fearing that a thin design could indicate a significant sacrifice for the battery life.
The battery life of your phone is influenced by multiple variables, as you keep your display brilliant or your phone has a weak signal from your carrier. How you use your phone also have a big impact. Anyone online can gain many different experiences with their battery life with their battery life with which they have a phone at work in their bags and examine it for breaks.
So, how do you know whether the battery life is good in the iPhone Air and iPhone 17 Series?
CNET has tested the battery life of the new Apple phone in three ways: via a story stress test, observes a video streaming test and battery life after daily use. We also tested the wired and wireless charging. Our lab data iPhone 17, 17 Pro, 17 Pro Max and even strong battery life for the wind, especially compared to the old iPhone model.
IPhone 17 Pro Max has great battery life
The iPhone 17 Pro Max Apple is driven to Apple’s new A 19 Pro chip, which allows the phone to be performed on a single charge by combining a steam cooling chamber, iOS 26 and a large batteries.
Large battery does not always mean higher battery life. Battery life has much more than physical size or power. In addition to Huawei, Apple is the only major smartphone maker that produces its own hardware and software and can tune its phones to turn off batteries smaller than most Android phones.
The iPhone 17 Pro and 17 Pro Max have a larger battery of last year’s 16 Pro and 16 Pro Max. If you are using only an ASM-canable version of both phones like the iPhone models sold in the US, your battery is even bigger because it takes the place where the SIM card tray will be.
Frustrated, Apple does not share the battery capacity of the iPhone and a part of the cause is its batteries often smaller than the Android phone. Fortunately, the EU needs the EU that publishes the power label that includes battery capacity on its site. Macrumors Only ESIM-Cable has found the ability of the models. You can see how the new phone batteries compare with 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 streaming tests) that allows us to compare battery performances on a phone with another. And since we have been using these tests for years, we can compare a new phone with old models.
For example, if you have an iPhone 15 and considering upgrading to an iPhone 17, we can tell you that the new iPhone will be a long battery life out of the box than your old.
In the 3-hour video battery test of CNET, where we stream a video on Wi-Fi with the screen with full brightness, the iPhone 17 series did a horrible work, even if the results were not dramatically better than the iPhone 16 series.
Except for the plus model this year, the iPhone 17 Pro Max is the only model with a large battery (one of the largest in the iPhone) and it has lost only 9% in the test. The percentage lost, the better. This is the first time an iPhone has been in a single digit and I should notice that we are conducting the test for the best score of 17 Pro maximum Motorola Raja (2024). Razr has a less powerful processor and a small main screen with a low resolution and low brightness.
The iPhone Air and 17 pro examinations declined by 15%, the iPhone 15 is equal to 15 and the iPhone 17 lost 11%, the iPhone is better than 15 and 16.
Something to remember is a 6.3-inch screen of iPhone 17 that supports a 1-120Hz variable refresh rate and a maximum brightness of a maximum of 3,000 nets, compared to the iPhone 15 and 16, with 6.1-inch display with 60Hz refresh rates and maximum brightest.
See it: IPhone 17 Pro Max has incredible battery life
The new Apple phones did well in the 45 minute tolerance test of CNET, during which I played games, stream videos, scrolled social media and took a video call. 17 Pro Max has simply reduced a single percentage, which is the best result this year, but behind the iPhone 16 Plus, which is 100% (the best result for any phone).
The iPhone 17 and 17 pro had the same results, decreasing by 2%, the standard iPhone 17 looks like the more incredible quality. The iPhone Air has declined by 5%, which match the iPhone 15 in the same test. For the sight, the air did better than the Samsung Galaxy S 25 series in this test and bound to the Motorola Raja Ultra.
The iPhone winds go through one day
The main application of the thin design and light weight of the iPhone Air. However, how many battery life can this thin phone have?
When we review the phones, we set up them as our daily drivers to use and examine them as our personal phones. Real-World Testing is often the best indicator of what a reader can expect from the phone.
I started each day with a full battery for the iPhone 17 Pro and 17 Pro Max and track how many batteries I had all day. I finished with lots of batteries every day – even after shooting pictures and videos or even after filming the screen full of brightness Video reviewThe Below is a chart that shows how the iPhone 17 Pro Max battery was performed for my first five days.
Similarly, CNET senior technology reporter again highlights al-Deti that he regularly reviewed the iPhone Air with about 20% of the day (after starting with the entire battery). He said that he would come down to 20% on heavy-use days as he was ready for bed.
“Impressively, the iPhone Air has been using it for the past few weeks I have been using it consistently all day long,” al-Dati said. “But in order to increase the battery life during the day I had to rarely touch the battery pack in that Magsaf, which assured.”

In our exam, a fully charged Magsph battery added 69% to the iPhone Air battery. When I asked him that he was advised to buy $ 99 Magsaf battery for the wind, al-Dati said he suggested it for someone who often used their phone and would not want to hunt for any outlet.
Al-Hathe said, “No matter how thin or soft the battery is, I don’t tend to carry it with me, if not knowing that I will go away from home for a long time,” said al-Hathe.
He also reviewed the Standard iPhone 17 and said that even after taking the picture, scrolling on social media, listening to audioboxes and music, texting and watching the video can easily last a little day after watching the video.
Al-Hatti’s review notes that for several days, he will start with a full battery from 9am to 5pm to 5pm, and after 12 hours, the charge is 44% to 47%. If she hasn’t had 17 recharge the iPhone overnight, she must have about 30% of her next morning.
The iPhone 17 series charges faster
There are new iPhone models (left to right): iPhone 17, iPhone Air, iPhone 17 Pro Max and iPhone 17 Pro.
There are two ways to charge the iPhone: one cable or with Magsaf (unless it is iPhone 16E, which does not have Magsaf, simply charging QI). For the wired charging, the Apple iPhone 17, 17 Pro and 17 Pro Max and iPhone Air suggests to use 40W charger with a 20W charger. However, the Apple does not include a charger in the box, only a USB-C cable, but the company sells 40 DB charger at $ 39 and 20W charger for 19 to 19.
In our 30 -minute wired charging test, new phones with 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. Apple says that 17 Pro and 17 Pro Max can recharge at 50% in 20 minutes. In our exam, the iPhone 17 Pro hit 53% and the iPhone 17 Pro Max hit 49% after 20 minutes.
The iPhone 16 and iPhone 15 are the same as the iPhone 15 and the iPhone 15 Pro, the iPhone air has reached 49% of our 30 -minute charging test with the 20W adapter.
In Wireless Charging or Magsaf Charging We have done a 30 -minute test with the latest Magsaf Charger and a 30 D. Power Adapter. IPhone 17 Series and Air iPhone 16 Pro defeat each iPhone that we have tested, which did better than Air and Standard iPhone 17 i
Which iPhone should you buy on the basis of CNET Labs Data?
Apple’s 2025 lineup consists of iPhone models to apply to different people.
Get the iPhone 17 Pro Max if you want the best battery life. Standard iPhone 17 has a great battery life and has a more expensive iPhone 17 Pro -out inch. And if you are on Team Air, be aware that the battery life is not great, but you should go through a day on a single charge depending on how hard you use it.
I should also notice that iOS 26 has a new adaptable power mode. This feature has learned the types of your phone’s use and the processor has learned “adapt” for the specific task, so it draws less than the battery. The new feature takes a week to start working. I launched it after I run the CNET battery test and update this story with any changes or improvements from it.
Lastly, if you have an iPhone and the only problem is that its battery does not charge as much as before, think about replacing it with a new one. Doing so will not only cost a few hundred dollars less than the new iPhone, but it can increase your phone life a few more years.
