I have an original MyT3g phone that I got ona new contract at the end of November 2009. This is with TMo on a two-line family plan and the other phone is GSM only. Two days ago, I got up to a dead phone. Turned out the battery discharged overnight. First time that has happened to me. I plugged it in and charged it fully, but ~12 hours after a full charge it completely discharged again--and I never used it for anything in that time. I charged it again and after about 5 hours noticed the charged had dropped to 59%. I went in to see what was consuming the battery the most and it reported Cell Standby, which I believe is the transceiver performing basic keep-alive with the TMo network. By the 12th hour the phone was completely discharged again. Ok, is this a bad battery, or is the transmitter having an antenna issue and thinking the nearest cell tower is now farther away (and thus using a higher transmission power level, which in turn discharges the battery faster? At the end of this contract, I am terminating this phone and 3G service (i.e. UMTS data plan) and replacing this phone with a straight GSM service. In the past year I have not really used any of the data services, and on those rare occasions its been rather poor in my area (suburb of Atlanta). I'm guessing I can live with a 12-hour phone for 4 months, but wondered if anyone else experienced eerily similar conditions and found a resolution. I am running the latest ANDROID OS.
