Summary: the battery that was supplied with the phone was useless and charge down after about an hour. When I bought the correct LG battery the phone operate properly. However, the phone is so slow that I could not load Facebook or Skype on it. in fact I had to go back to my old galaxy s3.
Excerpt: buying this phone was a huge mistake. it always crashes, overheats, apps most of the time don't work, shuts down on its own, and has poor battery life. i go through battery without heavy usage in 50 minutes. REALLY!? buying a g3 next time
