iPhone 17 Air Battery Capacity and Weight Allegedly Revealed

Apple is expected to launch an all-new ultra-thin iPhone 17 Air later this year, and while there have been plenty of rumors about the camera's overall design and thinness, we haven't heard any details about the device's weight and battery capacity until now.

According to the leaker going by the account name "yeux1122" on the Korean-langauge Naver blog, the 6.6-inch iPhone 17 Air has a weight of approximately 145 grams, while the battery capacity is 2,800mAh. The details allegedly originate from a "mass production confirmed sample." The blog has previously offered accurate insights into Apple's component strategy.

The claimed weight is similar to an iPhone SE 2 or iPhone 13 mini, which are 148 grams and 141 grams, respectively. As for the battery, the capacity figure is not unlike the iPhone 12, which has a 2,815mAh battery. However, the leaker's post does note that there remains a possibility that Apple will use a high-density battery in the iPhone 17 Air, which could increase its "actual capacity" by 15-20%.

Apple supply chain analyst Ming-Chi Kuo said in March that device will have a "high-density" battery. More recently, a report out of Asia has suggested that the iPhone 17 Air could become the first Apple smartphone to adopt advanced battery technology, with Apple supplier TDK preparing to ship its new generation of silicon-anode batteries by the end of June.

Having said that, reports have been mixed regarding the iPhone 17 Air's potential battery performance. The Information's Wayne Ma claimed the device will have "worse" battery life compared to previous iPhone models.

In internal testing, Apple apparently determined that the percentage of users who will be able to use the iPhone 17 Air for a full day without needing to recharge the device throughout the day will be between 60% and 70%, according to the report. For other iPhone models, the report said that metric is apparently between 80% and 90%.

To mitigate this problem, the report said that Apple is planning to release a battery case as an optional accessory for the iPhone 17 Air.

On the other hand, Bloomberg's Mark Gurman has offered a more optimistic outlook, stating that battery life would be "on par with current iPhones" thanks to hardware and software optimizations.

The 5.5mm-thin device is also rumored to incorporate Apple's power-efficient C1 modem and lack an Ultra Wide camera, which could potentially provide more internal space for a larger battery. We'll know for sure when the device replaces the "Plus" model in Apple's iPhone 17 lineup, which is expected to launch around mid-September, per Apple's typical fall release schedule.

Isn’t it paradoxical to design an ultrathin iPhone only to need a battery case to get through the day? It seems to contradict the whole purpose of making the device slimmer, prioritizing elegance and portability, only to bulk it up again for basic functionality.

People are going to make their jokes, but 145G is insane.
To put it into perspective, the iPhone 14 Pro Max was 240G. We’re talking about basically an entire iPod Touch in a case level of weight being just sliced off.
To put it even more into perspective, the iPhone 4 was 132G.
We are talking about a phone with a ginormous screen, but within 13 g of the iPhone 4.
Even compared to the iPhone 6+, we’re talking almost 30 g and 2 mm lighter and thinner respectively.
Anyone coming from pretty much any iPhone over the past seven years is going to absolutely notice the difference.
I wouldn’t even be surprised to see Mini fans who stick with that phone mostly because of the weight jump on the Air bandwagon, with the weight to size ratio it’s going to feel even lighter than that.

As much as I’d love a light iPhone, I won’t be the first wave of guinea pigs to test it out.

It’s bound to get super hot and slow it down.

Make no mistake about it, this iPhone Air is meant to look good in all their advertisements. After all, Apple loves to say, “thinest, fastest, etc. etc.”

Practically however, for day to day use, even the older iPhone models will better dissipate heat.

This model literally has all the attention and focus of the tech media for the last year. It isn't that hard to understand that people want form factor improvements, and want something that is more comfortable to hold and tote around. The 16 Pro Max is a god awful brick. I want something that was actually designed to be held in the hand by a human being. Not an afterthought.
Yeah, I don’t really get the criticism, a lot of it just feels like MR posters regular pattern of “Apple bad, no one wants this” based on nothing.
Between 2012 and 2022, Apple‘s flagship iPhone has gone from 112G to 240G. The most heavy iPhone, the 14 Pro Max, is literally double the weight of the iPhone 5, and even if we are just comparing the plus/Max version the original 6+ was still about 70G lighter and 2 MM thinner than today’s Pro Max’s.
For a device whose main function is portability, it is the one area where all phones have gotten significantly worse.

2800mAh + high density = something more like 3200mAh. Add into that efficiency improvements from the A19 of another 10-15% and you get something roughly equivalent to iPhone 16 battery life. Significantly less than 16 Plus, but pretty similar to 16. I'd say that's more than acceptable for the design they are able to achieve here. A 6.6" display with a case only 5mm thick and 145 grams is hugely impressive. Going to be the first enjoyable iPhone to hold in years.

I’d be happy to forfeit some battery life in exchange for a phone that is similar weight to my iPhone Mini.
