Yes, it turns off immediately and unexpectedly. I experimented using various applications (for photos, chat, etc...) just to see if they would work and they all do, the phone only works momentarily before going black and then it tries to restart itself. This occurs only when it is plugged in. If I try to turn it on by itself it doesn't turn on at all. This has led me to conclude it's a battery issue, though when the phone turns on, for those rare seconds, it shows battery at 100%. I've taken it in to get the battery replaced and if that's not the problem then I'll probably just wait until August when I return to the states. Unless they tell me it's something they can do here. Though I'm spending enough on the battery replacement as it is.
Thanks for all the advice.
