Halfway through the work day, you see your smartphones battery running into the red zone and you find yourself desperately looking for a charging port.

While the phones are getting more feature packed with huge processors and big camera’s the thing getting ignored is the battery. All these features pull out a lot of power which eventually hampers the overall battery performance.

Samsung Electronics hopes to eliminate the battery issue. The company has set a goal that smartphones coming out this year can last all day under average to moderately heavy use, according to Kevin Packingham, vice president of product innovation at Samsung.

“When you wake up to when you go to bed, we don’t want you feeling anxiety about your battery life,” he said in an interview at CES.

The company is working at optimizing different aspects of the phone, such as searches for Wi-Fi or powering up the 4G LTE radio. The Charge, Samsung’s first LTE phone for Verizon Wireless, was a good test bed for the company, but the company can do better. Samsung wasn’t quite there yet in terms of power efficiency, said Packingham.

So with this, we hope Samsung bringing out huge smartphones with greater battery life.

A good news for all the Apple iPhone fans, Apple has started to sell factory unlocked iPhone 4 at their US online store.

“Unlocked” simply means that a mobile phone is not bound to any particular carrier. In India, customers buy an Unlocked phone and easily switch between carriers by simply replacing the SIM card. Though in the U.S., the mobile phones are not sold separately they are always tied to a carrier.

The 16 GB iPhone 4 will cost US$649, while the 32 GB model will retail for $749, which is higher than it should actually retail but is cheaper than its jail broken counterparts being sold in India. A unlocked iPhone 4 used to cost around INR 40,000 in India which is quite higher than $649. So this step by Apple will prove to be a boon for international buyers.
