OnePlus may have developed a Qualcomm Quick Charge-like technology.

The phone maker has introduced three smartphones so far, including the OnePlus One, OnePlus 2 and OnePlus X, but it is expected to introduce a fourth phone in the coming months. It'll be the company's latest flagship, following the OnePlus 2 and OnePlus One (the OnePlus X is a midrange handset). We've already seen many rumours regarding specs, but now we've learned it could come with a new charging technology.

OnePlus has patented a charging technology called Dash Charge. Now, the US Patent and Trademark Office filing doesn’t mention anything specific, such as "fast charging" etc, but reports have looked at the patented name and assumed it must be similar to Quick Charge 3.0, the latest version of Qualcomm's fast-charging technology. That standard can refuel devices up to four times faster than conventional charging.

Last year’s OnePlus 2 flagship notably lacked a wireless charging option as well as a quick-charge mode. The next OnePlus flagship might come with Qualcomm's Snapdragon 820 on board, meaning it might also support Quick Charge 3.0, but OnePlus' new trademark filing has left us all wondering if the company might actually use its own technology for speedy charging.

We won't know for sure until the OnePlus 3 - the presumed name of OnePlus' next flagship - launches in the second quarter of this year. Until then, check out Pocket-lint's round-up of all the latest OnePlus 3 rumours, such as this report from GizmoChina about the flagship starting around $310 and coming in two possible variants: a standard base model, and a higher-end model.
