Regulatory documents reveal new Apple 49.9 Wh battery that could be upgraded to MacBook Air



The unreleased MacBook battery appears to have appeared in a couple of regulatory databases this month. The details aren’t clear, but new data from China’s mandatory certification database and UL Demko certification reveals what a Mac with model number A2389 and a 4,380 mAh battery looks like.

As Venkates Babu pointed out on Twitter, the battery voltage indicated in these sauces is high enough that the product in question is unlikely to be an iPhone or iPad. That means it’s probably some kind of MacBook, but the information here has remained unclear.

The 4,380 mAh battery in this document is relatively small on a Mac, but can be used on a MacBook Air. For example, the 1

6-inch MacBook Pro has a battery with a capacity of more than 8,000 mAh. The 13-inch MacBook Air has a battery capacity of approximately 5,100 mAh. The power listed here is also interesting. The figures show that the Mac in question has exactly the same 49.9-watt-hour battery as the 13-inch MacBook Air and is smaller than the 13-inch and 16-inch MacBook Pro.

With all of this in mind, it seems obvious that this battery is likely to be aimed at some kind of MacBook Air or even revive a 12-inch MacBook. Apple is the culmination of the move to Apple Silicon processors, and we would expect the next MacBook Air or MacBook to be powered by individual Apple processors instead of Intel. Apple said the first Apple Silicon Mac will be released later this year.

The Apple Silicon Mac is expected to be much more energy efficient than the Intel Mac. If these regulatory applications are related to the Apple Silicon Mac, the battery life is likely to be significantly longer than current Macs, given the improved performance of the Apple Silicon.

It remains to be seen which Mac will replace Apple Silicon first. An anonymous Twitter account @L0vetodream previously offered Apple to revive the 12-inch MacBook as part of Apple’s Silicon transition. Ming-Chi Kuo, a credible Apple analyst, meanwhile, said the 13-inch MacBook Pro and the new 24-inch iMac would be the first Apple Silicon Macs.

What do you expect to see from the Apple Silicon transition? Is there any specific Mac you’re most excited about trying out with Apple’s custom processors? Let us know in the comments!
