[iMore Question]

Is there anyway to fix this ?

Your options, as I see it, is as follows:

1. Get a qualified Apple tech to replace the battery, if you haven't already.
2. Don't rule out the chance that the problem could be something other than the battery.
3. Consider upgrading to a newer model iPhone.

Did you use the correct batteries? Were they Apple approved batteries? Do you notice any other symptoms other than the shutting off?

You should use the original battery.
