The Nexus Battery

I've recently purchased the Galaxy Nexus HSPA+ with Jelly Bean from the Play Store, and I must say the battery life is amazing. For the past three days, with Wi-Fi on, going through normal use, reading apps, some games (Final Fantasy iOS port -_-), light web browsing, and automatic brightness, I've been getting 17 hours worth of battery and still be at about 20%. I've never had a modern phone that could reach these figures without rooting and changing power consumption. I cannot wait for the next Nexus. Has anyone else been getting great battery life?
