Now your iphone screen goes black and on your itunes you will get pop up message that itunes is detected

it may show charged but i would get your batterty checked out.

sounds like a defective battery int he iPhone, since it is new I suggest you go return it for another one.

you need to hold bouth keys power and home untill the iphone is not switched off,and than switch it on again,untill the apple is on the screen..

your battery seems to have a damaged cell, replace the battery and it should run fine

Sounds like you have at least a broken battery. Apple should give you a replacement. If you're out warranty, you can try to open it and replace battery. If that fails you need a new logic board. You can get the part at iPad Repair and there is a guide that shows you how to open a kindle and install parts at iPad Repair Guide.

You'll have to let the iPhone charge sufficiently for it to proceed further from the boot screen. You may want to leave the iPhone charging for atleast half an hour before unplugging it.

From Apple Support:
Display shows a white screen

1. Turn iPhone off and turn it on again.
2. If the iPhone will not turn off, try to reset it. Press and hold the Sleep/Wake button and the Home button at the same time for at least ten seconds, until either the Apple log or battery symbol appears. If the battery symbol appears, continue to charge iPhone until it is fully charged.
3. If that doesn't work, try restoring the device.

welll hold the power and home button down at the same time and as soon as it turns off plug it in u should see a battery symbol that shows its chargeing
