I LOVE my EVO 4G, it is rooted with a great Sense based ROM, and I have a very good kernel for better battery life, But WTF This phone still blows chunks for battery life. Right now I am at 40%, been unplugged off the charger since 7:30 am, that is only like 6 hours, and it has been a quiet day, only made like 25 phone calls, and like 20 texts. And I bought my Wife the new Sprint nexus-S 4G, and she lost connection the entire day yesterday, her phone was a brick for calls and texts. Major issues being reported for terrible radio and connections o the new Nexus. It is not Sprint, but the ANdorid phones. I think I might make the switch to a jailbreaked iPhone4, maybe go Verizon. But is the iPhone4 really that good for battery life ? I need a smartphone that can last a full business day, make tons of phone calls, lots of texts, and e-mails, and still last me to dinner time.
