Earlier this week I spent some time driving around Kansas City in order to field test the turn-by-turn navigation, the LTE network, and the battery life. At 11:30 AM I started out and the battery of the Nexus was at 43-percent. After 25 minutes the battery had drained down to 33-percent even though it was plugged into a car charger.
Think about that. If you’re on a road trip and want to use the 4G LTE network to provide you with driving directions, your drive had better be shorter than 4 hours because even when plugged into a car charger, the battery will not last.
From Shawn Blanc’s review of the Galaxy Nexus. Wow.
