But does this electric phone come with an extra charge? Not at all -- it'll cost exactly the same as any of the other standard colours, so no need to let price cloud your judgement. 

Thunder colour aside, the OnePlus 6T packs cirrus-ly high-end tech, including an in-screen fingerprint scanner, but with a lower price than rival flagships. Weather the new colour helps it hit stratospheric popularity remains to be seen.
