Apple is scheduled to host its annual WWDC event next week. While we are expecting major software releases and updates to apps, the company is also rumored to announce new hardware at the event. In April, Apple announced the new iPad Pro models and 24-inch iMac with its powerful M1 chip. It is now rumored that the company will announce its highly anticipated redesigned MacBook Pro at the WWDC event. Seemingly, the 16-inch MacBook Pro has been filed in the Regulatory database ahead of the WWDC event.

Discovered by MacRumors, the 16-inch MacBook Pro has been filed in the Chinese regulatory database. The listing was filed back on April 14 by the Apple supplier Sunwoda Electronics. The listing is for a battery with a model identifier A2527 rated at 8,693 mAh/11.45V, which is similar to Apple's. The battery capacity and other details are pretty similar to the current 16-inch MacBook Pro model.
