The Huawei Mate 40E is confirmed by the Wireless Power Consortium
Huawei launched E variants of its Mate 30 series in China - in late 2020, in fact. Given the year the OEM has had, it may have gotten a pass for not doing the same with the Mate 40. However, it seems this flagship will get such a version as well.
A phone by this exact name has been approved to use 5 watt (W) wireless charging by a relevant interest group. This new leak also confirms that the Mate 40E's model number is OCE-AN00, whereas that of the Mate 30 Pro is LIO-AN00m.
The same device has also been revealed to look pretty much exactly the same as a Mate 40 (new Star Ring camera hump and all) in black through a recent TENAA listing. Then again, this page's SoC-related specs hint strongly at the Kirin 990 or 990E.
As the 30E Pro also ran on the 990E - an octa-core processor made up of 2 Cortex-A76 cores clocked at up to 2.86GHz, 2 others at 2.36GHz and 4 Cortex-A55s at 1.95GHz with a Mali G76-MP14 GPU - this might render the 40E a little redundant.
