I side-loaded the new Jelly Bean OS and have noticed a significant reduction in battery life. I did two complete FDR's and even formatted the SD card. I also "calibrated" the battery as instructed from a previous thread. I am getting maybe 6-8 hours out of my battery before it's time to hook up the charger. Use is very light...... a few phone calls (no more than 15 minutes in length), an hours worth of Facebook and Twitter (combined), no needless apps downloaded or running, and maybe 30 minutes worth of playing some music. I know I'm forgetting a few items but it doesn't amount to much time or usage. What gives?
