Chosen Solution
Hello everybody! I have a 4s 32gb with this problem: when I turn it off (holding on-off and sliding on “turn off”), it reboots itself immediately after. The problem doesn’t occur when the iPhone is connected to the pc. Why? I’ve already tried to replace the battery, but the problem persists. I’ve also tried to reinitialize in DFU mode, withouts results. Do you know what it can be? Battery connector, charging connector, on-off button….? Thanks Teo ITALY
open you iPhone and test it. unplug the power cable first. turn off device and check. if its still reboots, unplug the dock connector and check again…. have a nice repair iPhone 4S Dock Connector Replacement
My 4S did the same thing. I took it Apple and was told to buy a new phone. Another post on this site suggested cleaning the docking connector with isopropyl alcohol. I carefully did it with a tooth brush and IT FIXED IT!!! THANKS
I shut down using the two bottoms at the same time.
