anybody having battery issue with their phone since the el30 update? the last week, mine has been terrible. in a typical work day, i might check a couple emails on the phone and send a few text messages, and i would get 24 hours of battery. now, that same day, and i am lucky if i am getting 9 hours. i send two text messages yesterday, deleted a couple of emails and made one 15 minute phone call. took my phone off charging at 7 am, and it was dead at 6 pm. unacceptable. i was at my office and house where i have plenty of signal.
