According to Blass, the HTC U12+ will feature a 6-inch LCD screen with WQHD+ resolution and will be powered by Qualcomm's top-of-the-range Snapdragon 845 processor and 6GB of RAM. The device will be supplied energy from a 3,420mAh battery.
Those specs are near-identical to Samsung's new S9 Plus phone.
Blass adds that the HTC U12+ will sport two cameras on the rear (16MP and 12MP respectively), and two 8MP selfie cameras on the front.
As you would expect from a phone released in 2018, the U12+ will also boast an almost bezel-less design.
The HTC U12+'s release date is apparently scheduled for May.
Interestingly, there is still no sign of a standard-sized HTC U12. The HTC U11 was announced in April 2017 and then released on June 1, before being refreshed and enlarged in the HTC U11+, which hit shelves in December of last year.
It's common knowledge that HTC is having to scale back its portfolio after selling part of its phone-making business to Google, so perhaps there never will be a U12 after all, although it would be odd for the company to target the market for larger phones at the expense of standard-sized phones.
If the HTC U12 does materialise, though, then we expect it to launch at the same time or slightly before the U12+.
