4s shuts off while taking photo

[GovtLawyer]

Recently my 4s has started to act strangely. At least 1/2 dozen times the phone has turned off when I press the shutter button on the camera. I turn it back on and then take a picture without it turning off. So, at worst this is intermittent. However, it should not be happening at all. Any idea what is going on? The phone is around 2 1/2 years old and has worked almost flawlessly until now. Of course, it is out of warranty.

I have never dropped it and the case is protected. Outwardly, it is in excellent shape.

Battery?

My 3GS acted like that when the battery started loosing capacity.
Now my 4S is starting to shutdown the same way.
Both were about 2 1/2 years old when they started.

Explain this

Please expand the last reply. The battery is almost 100% and does not lose the charge quickly. How is the problem I have described a battery issue?

It sounded more like a possible thing to consider given that it was phrased as "Battery?" with a question mark. Given the additional battery details you provided it seems like that's probably not as likely in your case.
