So i upgraded to ICS, and now notice i get barely 1hr of web browsing before my battery is 20% after full charge. I have screen on auto, and only 3g enabled. I saw something about a .215 leak, is that a fix to the terrible battery since ics? before my battery rocked, now cant do anything. I am going to calibrate my battery, but really want a fix for this, its terrible. Id rather not root or use a custom rom.
