Lenovo's CEO, Chang Cheng, has been teasing the upcoming Lenovo Z5 flagship for quite some time now. We've seen some sample photos giving us a glimpse of the output from the dual camera. More excitingly we got a sketch of the design and a part of a press image, showcasing a front panel with nearly 100% screen-to-body ratio.

Yet this latest bit delivered by Chang Cheng is almost too hard to believe. According to it the Lenovo Z5 battery life is unlike anything we've seen lately. The CEO says it can last for up to 45 days of standby, which is just ridiculous by today's standards.

There's no information about the battery capacity itself, but we can assume it's going to be a big one. Still, 45 days of standby on a single charge can't be achieved by just increasing battery capacity, so there must be some new software optimization involved, probably aided by machine learning.

Really shaping up to be an interesting phone, this Z5 - we can't wait to see more of it. Ideally we'll soon get an announcement date.
