The OnePlus 2 aka OnePlus Two is in the limelight again with its release date drawing close. The Chinese smartphone makers are tight-lipped on the device but its key specifications have been leaked over the last few weeks.

The OnePlus 2 was expected to be unveiled on 1 June but it didn't happen. Now, reports have claimed that it will be launched in July without specifying the exact date.

As is the case with all flagship devices, the OnePlus 2 should come with specifications much superior to its predecessor. Going by the reports that have surfaced so far, the upcoming smartphone is expected to have at least five feature upgrades over the OnePlus One.

1) Display: The OnePlus One sports a 5.5-inch LTPS LCD capacitive touchscreen with 1080 x 1920 pixels (401 ppi pixel density) and its successor is also expected to sport the same. However, the OnePlus 2 screen could be protected by a Corning Gorilla Glass 4 compared to Corning Gorilla Glass 3 seen in the current flagship device.

2) Processor: Pete, Administrator of OnePlus forum, has confirmed that the OnePlus 2 will house a Qualcomm Snapdragon 810 v2.1 (new version of the SoC). He has also claimed that overheating issue of the processor has been solved with new version of the SoC.

On the other hand, the OnePlus One is powered by a Qualcomm Snapdragon 801 clocking at 2.5 GHz.

3) Operating System: The OnePlus One runs on Android 4.4.2 KitKat and is upgradable to Android 5.0.2 Lollipop, while its successor is expected to come running on Android 5.1 Lollipop.

4) Camera: The OnePlus 2 is expected to house a 16 MP main camera and 5 MP front snapper, while its predecessor has a 13 MP main camera and 5 MP secondary snapper.

5) Battery: The OnePlus One is powered by a strong non-removable Li-Po 3100 mAh battery but its successor is expected to come with an even stronger one - non-removable Li-Po 3300 mAh battery.

OnePlus is yet to confirm the specifications of its upcoming device but it won't come as a surprise if they are seen when it is released.
