One of the factors that kept an LTE "4G" radio out of the iPhone 4S was the compromise of the battery-draining next-generation cellular data transceiver. As many "4G" phone owners know, the advanced technology requires a lot of power, even when not in active use. Purported next-iPhone batteries seen in photos and sporting slightly higher specifications than existing iPhone batteries may, if accurate, suggest that Apple has overcome the LTE issue with a modest compromise.
