Now that you're rooted be sure to update your PRI and PRL (menu/settings/system updates) and learn about SetCPU and install to get a real boost in battery life
I assume you mean profile and PRL, not PRI . PRI is updated with the radios, and doesn't need to be updated if you're on the latest OTA, already. Also, rather than just updating profile and PRL, consider following the instructions here.
