Majin Bu’s first battery leak caused confusion

On August 1 2025 popular Apple leaker Majin Bu shared the first battery image and said it was for the iPhone 17 Air. He also said the battery capacity matched the old rumors. But later he deleted the post and said that the image was actually of the iPhone 17 Pro battery.
This caused some confusion in the Apple community because people were already thinking that the image was of the iPhone 17 Air battery. The battery capacity was similar to the earlier claims but the shape of the battery clearly did not match.
New leaker yeux1122 shares battery images that show ultra thin look
After Majin Bu’s post another Apple leaker yeux1122 posted new battery images. These new images show a battery that looks different in size and shape. These images are not confirmed but the size shown is surprising.
The leaker said the iPhone 17 Air battery is only 2.49mm thick. He also shared a comparison image with the iPhone 17 Pro battery. In the image the battery looks clearly thinner and there is a raised area that may have more connectors.
This battery design matches earlier iPhone 17 Air thickness rumors
Old rumors said that the full thickness of the iPhone 17 Air including the display and outer body will be between 5.5mm and 5.6mm. Now with this new battery leak showing 2.49mm thickness it matches those old rumors well. Apple is known for slim phone designs and this shows that they might be going even thinner this time.
What is the leak accuracy record of yeux1122
The leaker yeux1122 is known to have a better than average record with Apple leaks. He once said that the iPhone 16 Pro would have a 2TB storage option but that was wrong. Still many of his other leaks turned out to be true so people follow his reports closely.
In these new images the battery shape looks different from Majin Bu’s earlier image and there are small changes in the design and connectors. If this is true then Apple may be doing a big internal design change this time.
What does this ultra thin battery mean for Apple
If the iPhone 17 Air battery is really only 2.49mm thick then it could be a big design shift for Apple. A thin battery means a very slim phone design. But it also brings some challenges like heat control battery life and overall durability.
A thin battery makes it harder to control heating and if the battery capacity is reduced then phone usage time and performance can also get affected. But if Apple is using new materials or a new battery system then they might have solved these issues already.
What could this iPhone 17 Air battery leak mean for the market
This leak is not just about a battery it may be a sign of a full design shift. When a leaked part of an iPhone is so thin people naturally start guessing what Apple is planning. With every new iPhone Apple sets a new standard for design and features. If the iPhone 17 Air battery leak is true then this could be a big change in the iPhone design trend.
This leak is not confirmed but the chances are high
Apple has not confirmed anything yet but these new battery leaks have created a strong buzz. If the iPhone 17 Air battery is actually this slim then it will be a big step for Apple.
Fans and tech experts are waiting to see what Apple shows at the September event. Until then this battery leak gives us a clear idea that Apple might bring something very different and bold this time with a new balance of design performance and innovation.
