We're pretty used to anticipated smartphones being leaked by outside sources, but Lenovo's VP Chang Cheng isn't waiting on other to do the work for him.

Over the past few week, Cheng has been teasing some aspects about the upcoming Lenovo Z5 smartphone including an all-screen display, 4TB of storage and 45-day standby time, among other things.

Cheng partially revealed the upcoming Lenovo Z5's rear panel and it looks like it's going to come in a Huawei P20-like Twilight colour.

The interesting about this colour option is that you get a gradient purple and blue effect, which actually looks pretty attractive from the render.

The other big feature being highlighted is that the phone could come with a whopping 45 days of standby time on a single charge.

Cheng further claims that with this much storage the phone will be able to store around 2,000 HD movies, 150,000 lossless music files and around 1 million photos.

Recently, The Lenovo VP wrote a letter to the fans saying that the Z5 is a follow-up of the ZUK series that includes the Z1, Z2 Pro, Z2 and Z2 Edge.
