OnePlus 2, which received a virtual reality launch amid much fanfare, does not feature Qualcomm Quick Charge 2.0 battery charging technology, virtually a standard in today's newer smartphones.

This means users will have to wait for a significant amount of time until the smartphone's battery acquires full charge. An Android Police report, which quotes OnePlus, says OnePlus 2's battery needs more than three hours to acquire a full charge.

OnePlus 2 features a 3,300 mAh battery, which is a significant improvement when compared to its predecessor's (OnePlus One) 3,100 mAh battery.

The phone also incorporates an advanced Qualcomm Snapdragon 810 processor, which should have brought with it the Qualcomm Quick Charge 2.0 technology that promises to rapidly charge the smartphone's battery. This technology, it is claimed, charges a smartphone's battery to 60% in just 30 minutes.

Incorporating Qualcomm Quick Charge 2.0 could have done the China-based OnePlus a world of good, especially with respect to offering buyers a decent "business smartphone".

The recently released LG G4 features Quick Charge 2.0, apart from a host of other high-end smartphones.

The likely reason for OnePlus overlooking the Quick Charge technology could be the new USB Type-C specification.

Android Police reckons that incompatibility between USB Type-C and Qualcomm Quick Charge could have led to OnePlus omitting the more recent rapidly charging battery technology.

It is obvious that Qualcomm's Quick Charge technology demands the usage of a power controller that is compatible with the USB standards within the smartphone. The incompatibility between the new battery technology and USB Type-C could lead to development of new compatible power controllers in the future.

Nonetheless, the 3,300 mAh battery within OnePlus is said to have been tweaked to offer comparatively increased backup.
