We already know that vivo is holding an event on November 30 (teaser shown below) at which the X6 smartphone - which has already cleared TENAA - will be unveiled. Now, just a week before the event, another vivo handset dubbed X6 Plus has been spotted listed on TENAA's website.
While the TENAA listing reveals that the smartphone - which is already 3C certified in China - will come in two variants: the vivo X6Plus L and X6Plus D, it unfortunately does not include any specifications or images of these models.
Rumors say that the X6 Plus will be powered by a 10-core MediaTek Helio X20 chipset, and sport a 5.7-inch (1440 x 2560 pixel resolution) display. It is expected to come with 4GB RAM and 32GB internal memory, pack in a 4,000mAh battery, and feature a 21MP rear and 12MP front camera. Needless to say, none of these has been officially confirmed, so take it with a heavy dose of salt.
