I recently upgraded my phone and signed up for a plan on black friday, scoring a free droid razr. I was really happy when I received it. It looks awesome, and runs smooth. But, once I actually put it into action at my work and such, i found that it has less battery life then my previous phone (galaxy prevail.) Considering it's a pretty marginal upgrade, I find it odd that I do not have more battery life, or even the same amount. What's the deal? Any rootings, or other tools/tricks to help me work out my battery usage? It says my display was my main battery sucker, but I reduced it from 90% to about 20% and still having problems. I also noticed that talking on the phone is using a lot more then it should. For example, just today I had 2 phone calls, totaling about 20 minutes combined, for 7% of my battery life. At that rate, 3 hours of talking would nearly take out my whole battery.... There's probably threads about this stuff already, but i'm new here. Any help or direction would be appreciated, thanks.
