As expected, the next Galaxy should tackle a bigger battery, though it’s uncertain what the size will be. Some think we’ll see a 2,900mAh and others believe a 4,000mAh cell might be a possibility, though the latter seems more believable for the Galaxy Note 4. The most interesting tidbit revolves around the handset featuring new technology that fully recharges the device from 0 – 100% in just two hours.
