So I am coming from an iPhone 4 because of ICS. I have my razr updated already. However the battery life is horrible. There is no 4G in my area and won't be until later 2013 according to Verizon. My iPhone could go a full day without needing to charge and that's even using 3G to stream pandora and checking facebook and about half an hour or less of gaming. The Razr on the other hand can't even handle half a day. I have tried everything I can think of (setcpu, kill app application, ristricting data connections, using only wifi) and nothing seems to help. I am thinking of switching back to my iPhone and selling my Razr. I do like ICS and droids, I had a Droid X before my iPhone and a Droid before that. But battery life is a big factor. Anyone have any suggestions on how to improve battery life?
