4K for Cell Phones May be a Bad Idea

In an interview with the Chinese smartphone manufacturer Huawei at Trusted Reviews the primary problem with 4K screens on a cell phone is identified as: “The power consumption would be so huge that your phone would last just half a day”.

While we at 4K rumors are normally in favor of all things 4K, this is the one area where it has not been demonstrated clearly enough that 4K is truly a worthwhile benefit on the relatively small screens of cell phones.  The pixel density of 1080p is decently high already, and the 2K displays on phones are getting close to the limits of the eye can distinguish at normal viewing distances.
