The OnePlus 9 and OnePlus 9 Pro will launch in 2021 and they will both have a charger included in the box. In any case, this is what Max Jambor announces, who generally has good information about OnePlus.
Always a charger in the box of OnePlus 9
It evokes first the battery capacity of the two smartphones. It would be 4,500 mAh. The OnePlus 8T already has a battery with this capacity. We can therefore expect the battery life to be similar, if not identical, with the 2021 models. Users can perhaps expect progress if OnePlus has managed to do some software optimization.
Max Jambor evokes then the charger in the box of OnePlus 9 and OnePlus 9 Pro, in response to a person asking about it. “Is there a charger in the box?” The user asks. “Yes,” the leaker simply replies.
This choice to put a charger in the box of the next two smartphones is interesting. This shows that the manufacturer will not follow Apple and Samsung who have withdrawn the accessory with their iPhone 12 and Galaxy S21. In the case of the OnePlus 9 and OnePlus 9 Pro, it should be a 65W power adapter with Warp Charge technology.
