You could save up to $1,100 on a new OnePlus Open by trading in your old phone, bringing the cost of the foldable down to $599.
The Open also has a better battery capacity compared to the competitors, boasting a 4,400mAh capacity that should easily last all day. In addition, its fast charging feature allows the device go from zero to fully charged in just around 45 minutes, which is pretty fast for any smartphone, never mind one with a foldable display.
