Previous smart phones I owned turned wifi off when the screen went dead. So essentially wifi didn't really drain any battery and wifi was easier on the battery then 3g when actively pulling down data. So now I am on a 2gb plan (previously on unlimited) and sensitive to this I keep my wifi on all the times to use my home connection when possible. My battery however is barely getting through a full day. My wife was getting solid days but she had wifi off. Do you think that this is effecting it? I use my phone quite a bit throughout the day... Thanks much!
