Up until now, we've believed that the Perfume would sport a 5.1-inch display on its front, marking a slight increase over the One M9's 5-inch screen. A new rumor has just been posted by leakster @LlabTooFeR, claiming that the display on the new device will be even larger, hitting a 5.2-inch diagonal. That aside, nothing else seems to be changing, as the rumor mill still claims the handset will have a 1440 x 2560 pixel (QHD) resolution and a Snapdragon 820 SoC under its hood. On the software side, the phone is said to come with HTC's Sense 7 UI, built on top of Android 6.0.1, with a Sense 8 update coming shortly after launch.
HTC Perfume is going to have 5.2'' WQHD screen instead of reported earlier 5.1'' screen ;)— LlabTooFeR (@LlabTooFeR) February 8, 2016
The time for the One M9's annual upgrade is drawing near, but we've yet to hear any concrete information on when the new HTC flagship will be available. Perhaps HTC has moved its schedules around a bit, or maybe its just doing really good at keeping information from leaking out.
