The days of juicing up a couple times a day just may be over if Samsung has it's way. Kevin Packingham, VP of Product Innovation at Samsung, says "When you wake up to when you go to bed, we don't want you feeling anxiety about your battery life." Thats quite a bold statement when the standard nowadays is screaming fast processors and screens packed into a very small space. Not to mention features, features and more features.
The South Korean company will achieve this by moving to larger batteries (obviously), ala Moto RAZR MAXX, and tinkering with how the device searches for Wi-Fi. Polling for LTE signal will also be optimized along with how often it powers up the LTE radio. As it stands now, LTE is a huge power draw which has caused owners of LTE handsets to pound their fists with displeasure.
The Charge was a good test bed for Samsung but they say "they can do better" and admit that they "weren't quite there yet" in regards to improvements on power efficiency.
Things just keep getting better and better in the smartphone industry. Imagine the day when battery life is a non-issue. Well that day just may be coming in 2012.
