Sony Ericsson Battery Sony Ericsson C905a Battery Drained Quickly With Red Light Blicking?

Sony Ericsson C905a battery drained quickly with red light blicking? - sony ericsson battery

This phone holds the battery drains very quickly, eg 2 days with only 30 minutes of talk time, does not use any other functions. I've had for 2 months. I saw a red light Blickling hand, may be the cause? You mean you have to take the computer to connect to some upgrades?
Thank you!
