Verizon JB destorys battery.. questions about rooting..

view story

http://androidforums.com – Hey everyone. Long time lurker, first time poster. Apologies if this is a repeat/dumb question but... I upgraded to JB OTA last Friday and its been destroying my battery. Tried disabling as many apps as I could (like currents and maps via location settings.. etc).. but my battery is still getting slaughtered compared to stock ICS. Thinking about pulling the trigger and finally unlocking and rooting this beast. I'm assuming that custom Roms and kernels influence battery life quite a bit.. anybody have any suggestions on quick ones I should use? Thanks ya'll.. (General)
