OnePlus 9 Pro gets a slightly smaller 4,500mAh battery this time as compared to its older sibling. The phone supports 65W wired fast charging technology and bags a dedicated 50W wireless charger. In the PC Mark test, the phone’s battery life lasted for 9 hours and 42 minutes. OnePlus 9 Pro ticks almost all the prerequisite boxes needed to get the premium flagship badge, but the optics is one of those areas where the device still sings the same old saga. The Chinese brand has yet again reserved the 48-megapixel sensor on the OnePlus 9 Pro’s primary camera slot. OnePlus 9 PRO instead of a Sony IMX689 sensor, it now gets a Sony IMX789 sensor. The ultra-wide sensor has been bumped up to 50-megapixel. The phone also features an 8-megapixel telephoto lens and a 2-megapixel depth sensor for portraits.
