With up to 8GB of RAM, 3700mAh battery, Snapdragon 845 SoC, a huge 6.4-inch display, and an in-display fingerprint sensor, the newly released ‘flagship killer’ OnePlus 6T has most of the things you would expect from a high-end phone. However, it lacks the 3.5mm headphone jack, which a lot of manufacturers are ditching anyway, and it doesn’t offer wireless charging either. The company’s CEO Pete Lau, who also happens to be its Product Manager, recently explained the decision to omit wireless charging and the 3.5mm audio jack in a media briefing.

First off, he said that it is not possible to create a product which everyone likes, which is true. He says that the removal of the headphone jack made space for the larger battery and the in-display fingerprint sensor. This is a little hard to buy, as the headphone jack could have been relocated and moreover, some smartphones on the market such as the Vivo X21 UD have both a 3.5mm connector and an in-display fingerprint scanner.
