Hi, I am a new Optimus/Smartphone user, and I have some basic questions regarding battery life: 1. Should I use a program like Juice Defender? Does it actually work? 2. Does turning on USB Debugging actually work? 3. Should I only turn on 3G or Wifi when I want to go on the internet and leave it turned off the rest of the time? 4. Any other general tips? Thanks, this forum has been extremely helpful so far. I absolutely love this phone, but the battery just drains so quickly. After charging all night Saturday night, the battery had drained to below 40% by around 1pm on Sunday.
