CES 2013, the world’s biggest gadget show, has ended and has revealed bigger TV’s, smart refrigerators, cool watches, mobile phones that bend and a large array of some very hip mobile phone covers. Over 150,000 professionals searching for the next big technological breakthrough got a peek at over 20,000 gadgets that were introduced over five exciting days of technology and electronic gadget networking.

Samsung’s new flexible screen technology is absolutely mind blowing and will definitely have a hand in changing the mobile phone market. Looks like drop tests will be a thing of the past.

With the technological advancements introduced at CES, there is one problem that 5 billion mobile phone subscribers will have to live with just a bit longer.

Mobile phone battery life has been a long time and very frustrating issue that has yet to be solved. With Apple suing Smasung and HTC, and Samsung issuing their own patent infringement suits when it comes to mobile technology, you would think one of these companies would figure out how to build a battery that can last the day.

A company called uNu is cashing in on the mobile phone companies’ inability to produce a decent battery. Unu showed up at CES with some good news for heavy mobile phone users. The uNu DX Protective Battery Case, for example, will extend an iPhone 5′s life for two days on one charge.

While every iPhone user would love to get their hands on one of uNu’s battery packs, one has to wonder why the big mobile companies are incapable of building a battery that lasts.

What phone are you using and how long does it last?
