Iphone 4s, I have for about 4 years. I have replaced the battery a number of times and was working perfectly. Completely dead. Does not respond to switch on button at top. Battery was charged at the time.  Had been using it in my car (bluetooth playing my Iphone music). What should I check?

First, it could have died. I parted with my own iPhone 4s about 6 months back as it had served its time and could not run newer IOS and applications.

Second, plug the phone into its AC USB charger (not a computer). Let it sit for 30 minutes. Unplug. Hold the top button down and continue to hold it down until you see Power Off. Swipe that OFF. Wait a minute and plug it back in to the AC USB charger and see if it starts.

Third, no luck, visit the Apple Store and see if they can make it run.

Will try. I have already let it sit for 30 minutes, unplugged it and held the top button down. No 'Power Off' appears. Doesn't sound good.
Out of interest when you say the phone could have died? What part of it is most likely to give up the ghost?

Most likely a part (component) on the main circuit board has died. It is possible the charging circuit went bad. It is impossible to tell from this vantage point, but that is why I suggested the final step of visiting the Apple Store.

John you are a genius. I ran the changer for an hour. Mind you I had intended to leave it a little longer before disconnecting. Then suddenly there was three loud 'bips'. The phone had opened and was registering a tiny red line of battery. It was charging and is doing so now.
Could it have been that using the phone with my car's Bluetooth (to play Music) had drained the battery?
In any case it is back working and you put me on the right direction.
I had connected the phone to the charger earlier for a couple of hours, but nothing had happened. It was a different charger setup.
