Iphone 5 won't get past the apple logo

Hi,

My phone died last night and i put it on charge, the apple logo appeared but nothing more. I tried to reboot the phone numerous times by clicking the home and power button together, ive tried leaving it over night on charge, and ive also tried to plug it into my mac and restore it. This morning i tried the same methods of which none worked however at one point it clicked into the welcome page to swipe across and then entre my wifi details, i added those and continued to click the back up from itunes option, it backed up and restored and completed, however the apple logo appeared again and didnt boot into my home screen so im left with the apple logo still on my screen and no further.

Any help would be massively appreciated!

Thanks
