The OnePlus 3 has got a major upgrade especially in terms of its processor and RAM. The 6GB RAM is a benchmark that many flagships will aim for in 2016, including the Samsung Galaxy Note 7, which is also rumoured to carry the same RAM capacity.

As for the processor, the Snapdragon 820 is a popular choice among smartphone manufacturers for their premium devices and OnePlus has also decided to stick with it. Both cameras have been upgraded with the rear camera giving competition to recent releases like the Moto G4 Plus that also has a 16MP sensor.

Sadly, there are no design changes which may be upsetting for some who sought a new-look device. However, the display panel has been replaced from an IPS LCD to an Optic Amoled one which consumes far less power and is the popular choice among manufacturers. This is also the reason why the battery capacity has been slightly lowered to 3,000 mAh from 3,300 mAh capacity of the OnePlus 2.

The device runs on Oxygen OS, based on the Android Marshmallow just like the OnePlus 2. For a long time OnePlus fans hoped the company would someday switch to Cyanogen like the OnePlus One, but that seems highly unlikely now and Oxygen OS is what will prevail for OnePlus phones.

Coming to the price, the device will be available for £309 ($399) in grey colour and a gold-coloured variant will be available later. This is congruence with what IBTimes UK had reported earlier. The devices will sell directly from OnePlus' website without the company's controversial invite system.

The mid-range price of the handset with flagship specification gives the phone a great competitive edge over the Galaxy S7, HTC 10 and others. The 6GB RAM is the biggest advantage for the phone, which none of its closest competitors like Xiaomi Mi5, LG G5 or even Galaxy S7 possess.
