This is a new Galaxy Note about 1mo old. I am running the Go Launcher as opposed to the Samsung Launcher. Phone is not rooted or anything done to it. Have also updated to ICS. The battery life is terrible. From reading around samsung say standby time is 40 days with the average being 21 days (according to one site). Go power master on the phone is reporting standby time of 143 hrs (approx 5 days). I don't have a problem with either figure but I am not even getting that. Overnight in 12 hours I have lost a bit over 45% of battery whilst in standby and this while it was in flight mode with no connection chips active. My brightness is at almost the lowest it can go - about 2%. I don't know what is up with it, I am certain this is not normal. I don't have many apps on this phone, the usual BBC player, news and so on and the only thing I think can cause this battery drain is possibly WEBROOT antivirus. Could this be the cause? If this is the cause is there a free antivirus which doesn't suck the life out of a phone please?
