All iPads iPad Air 4 has a 7,673 mAh battery

[JPack]

According to Apple, the iPad Air 4 has a 28.93 Whr battery or 7,673 mAh.

For comparison:

• iPad Pro 11" (2018) - 29.45 Whr
• iPad Pro 11" (2020) - 28.79 Whr

What's interesting is not the capacity of the battery. Rather, it's that Apple designed and certified a new battery just for iPad Air 4. They didn't use the iPad Pro 11" battery even though it's virtually the same in capacity. That suggests Apple has a long term plan for iPad Air 4 and could be leaving space for 5G antennas, for example.

For comparison, the iPad Pro 10.5" and iPad Air (2019) share exactly the same battery. The iPad Air (2013), iPad (2017), iPad (2018), iPad (2019), and iPad (2020) also share exactly the same battery.

That’s actually an interesting observation. Nice work detective! ?️‍♂️

I imagine the board on the Air 4 is a bit simpler/smaller vs the Pro, as well as there is a bit more thickness, and room from two less speakers. All of that culminates in a bit more room for battery.

My 2020 11" has an excellent battery life and at a similar battery capacity for the Air 4, this thing is going to last forever considering 60 Hz screen and the A14 chip.

Are you thinking the Air 4 would get better battery than then Pro given its 60 Hz screen?

I think that’s pretty much what he alluded to


edit: although on apples website if you do the comparo the battery life is the same across the board

I remember on one of the review videos by some YouTuber, they found the 11 Pro had better battery life. Go figure.

Very interesting. I’m worried about getting a air 4 because the battery of my air 3 is so good. But I want the air 4 all the same lol

Doesn't the Pro go lower than 60Hz when there's no movement on screen? Also when watching full-screen videos that are lower than 60fps. In those scenarios it should be more energy efficient.

Nice observations btw!
I think Apple are not saving space for 5G antennas lol, these will not be added until next year's model. They rarely do mid-year refreshes, as far as I know. Especially when a product has such a high demand as the new Air.

Why different battery from the Pro? Apple sells enough units of this model to justify a different battery. I think the battery's shape is the last thing to be determined when putting things together in the case, it will basically fill in any space it can. The speakers and space around them was changed, and I imagine there are other changes compared to the Pro in the boards.

Another possibility is that battery tech changed. Batteries get better, though not that fast nowadays, so maybe Apple updates their chemistry, anodes or whatever every 2-3 years. Not sure.

Who knows, maybe the 2021 Pro will share the same updated battery.

Yep.
The iPad Pro displays can go as low as 24Hz and as high as 120Hz, hence they are great for Drawing, Editing and watching Movies on, AnandTech covered this well in their 2018 iPad Pro review:

In addition, Apple’s iPad Pro offers their ProMotion technology, which means it is a 120 Hz display, but one that supports variable refresh rates in order to lower the display's refresh rate for power management purposes. The iPad Pro will go as low as 24 Hz, presumably chosen to match the framerate of most movies.

GSMarena also did a write up about it back with 2017 Pro:

The iPad does this on the fly depending upon the content you are watching so if you are looking at a still image with no motion on the screen it can drop down the refresh rate to 24Hz to save power and you would never notice it. If you are watching a movie, it can switch to 24Hz or 48Hz depending upon the content. For everything else, it can switch to the full 120Hz. The flexibility allows more power savings and also get an accurate refresh rate to match your content more precisely, eliminating judder and distortion.

It's hard to understand the importance of a high refresh rate display until you see one in person. We may not have seen the iPad Pro displays yet but 120Hz gaming monitors have been around for years now and the difference is staggering, to the point where many gamers choose higher refresh rates over higher resolution any day as it actually helps with gameplay and makes things more responsive. iPad Pro not just has high refresh rate but also crams in a crazy number of pixels with a wide DCI-P3 color gamut and HDR support (coming in iOS 11).
