On iPhone 4s usage time equal to stand by time. Battery discharging little bit faster then usually not like 3GS on 4.2.1 last year. All I was using last three days its digital av adapter for TV and safari
that usually means there is some app running in the background that is still running - have you tried bringing up the task manager and closing all apps - or doing a hard reset on the phone?
Task manager - no. Hard reset - yes. But I can't understand with app, I tired making reset
