My Iphone quit working out of the blue?

I was charging my Iphone 5s, left it on the counter, went outside to do something, came back in a minute later and my phone is completely dead. It won't light up, charge, ect. I considered the fact that it may have just been frozen but it's been like this for awhile now… I have no idea what's going on… It just stopped working for absolutely NO reason! What happened? It has a cracked screen thats been like that for a few weeks, but other than that it has no other damages.

I would recommend trying a different charger. It may just have run out of battery and not charged. Either that or maybe your battery is just completely dead. If it doesn't work then bring it to the apple store. They have great customer service and you may get a new one if you're still under warranty.

Press and hold home and power at the same time for about 45 seconds. It'll come back on
