Why won't my 4s turn off?

Step one in replacing my iphone 4s's battery is to turn the phone off. It repeatedly reboots to "on" whether I use the on off button or the assistive device touch technique.

Other suggestions besides just letting the battery go dead?

Answer this question I have this problem too

Is this a good question?

This is most often caused by short circuit of the charging port. Clean the charging port very well with toothbrush, Isopropyl Alcohol, lint free cloth, etc. If after thorough cleaning still reboots with OFF, then the next step would be replacement of the charging port with the attached flex cable.

You could let the battery drain or just removed it with a anti static screw driver and spudger

Wow! After calling Rogers and Apple several times today, I saw the suggestion here about cleaning the charging connection with a toothbrush! I felt like an idiot doing it, but darned if my phone finally turned off after a good brushing!

I have been trying for 24 hrs with no luck to turn it off, and the toothbrush did it! Just a dry soft bristle brush!

Beats paying for a replacement phone or being without it when I send it in for repairs!

Thanks for posting everyone! Your ideas do help
