It turns out a briefly present always-on display mode was buried in the settings of the new phone, as a Redditor discovered, but it was removed in a day one update.
The reason of its removal? The OnePlus team didn't want to impact the battery life by including the battery siphoning display option popular in other Android phones.
True enough, we've tested the OnePlus 6 and found its battery performance to be strong, thanks to its 3,300mAh battery capacity and 1080p resolution screen.
More to come for OnePlus 6T?
The reaction to the news of this axed OnePlus 6 always-on display feature is mixed, with many 'Don't care' replies, and others determined to find a way to reactive it.
But you may have to wait until the inevitable OnePlus 6T to get official support for an always-on display. The good news is that may only be six to eight months away.
