I'm new to the world of Samsung. On my HTC Inspire, I could tell it what things to alarm for, blink for, vibrate for etc. I've basically figured out finally how to tell my G3 to not ding everytime I get an email. I like my phone to ding for missed calls and texts but not email. I finally figured out how to do that. I also like the phone to blink when I miss a call or text but not for email. After much frustration, I have finally figured out that as far as the led light, it's all or nothing. I can either enable the light for all missed calls, texts and unfortunately, emails or I can get no notifications period! So my question is how bad does that blinky led light run down a battery. I don't have my phone with me every moment and it might blink for an hour or more on occasion if I have an email etc.
