Regulatory filings reveal new Apple 49.9Wh battery, could be for updated MacBook Air

It looks like an unreleased MacBook battery made its way through a couple of regulatory databases this month. Details are unclear, but new filings with the China Compulsory Certificate and UL Demko certification database reveal what appears to be a Mac with model number A2389 and a 4,380 mAh battery.

As Venkatesh Babu pointed out on Twitter, the indicated battery voltage in these presentations is high enough that the product in question is unlikely to be an iPhone or iPad. This means that it is likely to be a kind of MacBook, but the details here remain unclear.

The 4,380 mAh battery featured in this presentation is relatively small in Mac terms, but it could be destined for MacBook Air. For example, the 16-inch MacBook Pro has a battery of more than 8,000 mAh. The 13-inch MacBook Air has approximately a 5,100 mAh battery. The power indicated here is also interesting. The submissions indicate that the Mac in question is a 49.9-watt-hour battery, which is exactly the same as the 13-inch MacBook Air and lower than the 13- and 16-inch MacBook Pro.

With all of this in mind, it seems clear that this battery is likely going to target a MacBook Air of some sort or even a 12-inch MacBook revival. Apple is on the cusp of its transition to Apple Silicon processors, and we would expect the next MacBook Air or MacBook to work with Apple custom processors instead of Intel. Apple has said that the first Apple Silicon Mac will launch later this year.

Apple Silicon Macs are expected to be much more efficient than Intel Macs. If these regulatory filings are related to an Apple Silicon Mac, the battery life will likely be significantly longer than current Macs given the improved efficiency of Apple Silicon.

What remains to be seen is which Mac will be the first to make the switch to Apple Silicon. The anonymous Twitter account @ L0vetodream previously suggested that Apple would revive the 12-inch MacBook as part of the Apple Silicon transition. Meanwhile, reliable Apple analyst Ming-Chi Kuo has said that the 13-inch MacBook Pro and a new 24-inch iMac would be the first Apple Silicon Macs.

What do you expect to see from the Apple Silicon transition? Are there any specific Macs you are excited to try with Apple custom processors? Let us know in the comments!
