My wife finally gave into upgrading her Razr to ICS, after getting tired of declining the upgrade notifications. Now her battery life is nothing compared to what it used to be. What I'm wondering is if rooting, and putting on a rom would help her battery life. I know this helped my D2, but very inexperienced with the Razr, since it's hers and she usually tells me not to touch it. She uses it mainly for texting via google voice, a bit of internet and facebook. Far from power user, just want something to get her battery life back to close to what it was before.
