A hinge assembly with an oil-retaining collar has a barrel, a pintle assembly mounted in the barrel and an oil-retaining collar mounted around the barrel and is filled with lubricant to allow the pintle assembly to rotate smoothly. The oil-retaining collar prevents the lubricant from flowing out of the barrel and prevents a plastic housing of an electronic device from being corroded and electronics from malfunctioning.
