My last 3GS had a godly battery. Of course something happened and I had to exchange it. The replacement? Not so much. I've already calibrated it and from 9am to 6:30pm checking my email once and some light texting my battery was at 61%. That's already terrible if you ask me. I just took a call that lasted 14 minutes. Hung up and my battery is at 53%. This seems ridiculous to me. Should I take this in before I apply and waste another BSE? Edit: Dropped another percent while I was typing this.
