hi folks, lately i have notice my battery life draining down slightly a bit quicker than what i'm used to. i barely make calls very often throughout the day and the phone spend most of it time on standby, but very often i press the power button to check the time and press the power button again to turn off the screen. but not thing unusual from my day to day usage pattern at all. is there some kind of newer firmware revision that automatically updated over the air that causes this? i don't normally think about my battery life, but lately the battery cycle pattern change a bit to get my attention to it.
