Chinese regulatory filing hints at updated 16-inch MacBook Pro battery, possible next-gen notebook that could be announced at WWDC 2021

Once again, it might be the regulatory filing that hints at a really cool thing just around the corner.

A Chinese regulatory filing for what appears to be a 16-inch MacBook Pro battery has been sighted ahead of a rumored WWDC 2021 announcement.

The regulatory listing, filed on April 14 by Apple supplier Sunwoda Electronic, doesn’t specifically mention Apple. However, it carries a model identifier of A2527, which lines up with Apple’s other model numbers.

Within the filing, Sunwoda Electric stated that the battery is rated at 8,693 mAh/11.45V. This places its operating specs very close to the current 16-inch MacBook Pro battery, which is rated at 8,790 mAh/11.36V.

While the filing doesn’t offer any details as to Apple’s MacBook plans, it matches up with rumors about next-gen MacBook notebooks.

Apple is largely expected to unveil a new 14-inch MacBook Pro and 16-inch MacBook Pro model with upgraded M1 chips in 2021. Those devices could sport a new 10-core Apple Silicon processor, a miniLED display, and a slight chassis redesign. The models could also bring back a MagSafe power port, SD card slot, and an HDMI port.

Should the leak turn out to be accurate, it could indicate a very slight decrease in battery capacity. Still, given that the Apple Silicon architecture is more energy efficient than Intel’s, the new unit could offer identical – or improved – battery life.

Stay tuned for additional details as they become available.
