Somewhere on the these forums someone wrote of charging problems with a phone. They solved with alcohol and Q-tips on the contacts.
Whoever you are, THANKS.
On the touchstone the phone would charge but about 1 AM or 3AM the charging chime would sound every 60-120 seconds. Cannot sleep well with that.
I have 2 Pre 3's so changed several things including swapping the back cover and the problem moved to the other phone. I read the forums and found the alcohol /Qtip idea but use alcohol prep pads. I cleaned the contacts on the phone and on the back cover on both phones.
TO SOMEONE OUT THERE.....MANY THANKS
