Samsung understands that battery life is a big problem when it comes to smartphones. The company is looking to fix that, however, promising that all Samsung smartphones coming out this year will last all day on a single charge with average to moderately heavy use. “When you wake up to when you go to bed, we don’t want you feeling anxiety about your battery life,” Samsung VP of product innovation Kevin Packingham said in an interview with CNET. Motorola recently announced the DROID RAZR MAXX, a variant of the DROID RAZR featuring a massive 3,300 mAh battery. Samsung will also move to larger batteries, though the company plans to focus on optimizing different aspects of the phone as well, according to Packingham. The changes will come from the way a phone acts when searching for Wi-Fi, to the way it connects to 4G LTE networks. Packingham acknowledged that Samsung “wasn’t quite there yet,” in regards to the company’s first 4G LTE smartphone, the DROID Charge. Despite these upcoming improvements, Packingham noted that power users will always face problems with battery life.
