Reaching the battery, we are quite happy to see that Huawei has stuck to its pumpkin flavored colored pull tabs, which allow for heatless battery removal.

The Li-Ion battery in the Mate 40 Pro is 16.94 Wh (4400 mAh, 3.85 V)—slightly less capacity than the 17.32 Wh (4500 mAh, 3.85 V) cell we found in the Mate 30 Pro.

Those two connectors are very likely two separates routes for electrons coming in via a wire vs. those coming in through the air as seen in the iPhone 11 Pro.

The Mate 40 Pro can also dole out 5 W to another device via reverse wireless charging.
