Hauwei Isn’t interested in 4K display for its Smart phones: too much battery drain

While the race to a smartphone with full 4K display is already supposedly on, with several companies rumored to be working towards ultra HD in their phone screens, Hauwei, the massive Chinese electronics maker, simply isn’t interested in the effort.

The company has made it clear that it won’t be using 4K displays in its smartphones at any time in the near future and according to Hauwei’s president of Handset Product lines, Kevin Ho, the massively detailed screen resolution would simply drain too much battery life and this is a pointless compromise in the company’s eyes.

Mr. Ho explained that “4K needs a lot of power so to use it, you have to make compromises. A 4K display on a smartphone may give you half a day of battery life but a 2K display can give you maybe one day or more”.

The simple fact of the matter, according to Ho, is that, since 4K display has 5 times the resolution of Full HD display, the power consumption across the board for all display activity will be 4 to 8 times greater.

The Hauwei executive also explained that, while 4K display looks impressive on large screens, it’s nearly impossible to tell the difference between 2K and 4K resolutions on any tiny smartphone screen that measures just 4 to 6 inches maximum.

Nonetheless, Hauwei seems to understand that what drives consumer demand isn’t always the obviously practical and thus the company isn’t ruling out 4K screen implementation at a later date. They’d first like to wait for the overall technology needed for 4K screens to develop further instead of jumping the gun and giving consumers phones that have screens with unnoticeably better display but last only half as long between charges.

Other phone makers like LG nad Samsung are definitely gearing up for 4K screens on their devices

Other technologies needed for effective 4K display in smartphones and tablets include much faster processing via the SoC chips that go into these devices. In this area at least, the problem still being faced by battery technology isn’t the case.

Nvidia and Qualcomm are already developing or have released the latest SoC chipsets that will let phones deal with 3840 x 2160 pixels. Qualcomm’s Snapdragon 810 chip being the most notable example.

Thus, whether Huawei participates in the early days of 4K smartphones or not, the technology is coming and consumers are going to want it.
