Solved! Phone won't turn on after charging for 13 hours.

I have an Optus Smart X Phone, and brought a new charger for it the other day. My phone was completely dead, pressing the power button, the red no battery sign appeared. I plugged my phone in with the new charger, it turned on, appeared to be charging so I left it for about 13 hours. Came back, took it off without turning it on and next day I find out not it will not turn on. Holding power does nothing, no boot up, no battery symbol, just cold black screen. Doesn't even start. I'm not sure what I did wrong. With my phone, I think the battery is ATTACHED so I'm screwed in that department (taking it out and putting it in)

So issue was that it was not turning on before this new charger correct? Could be the phone is just dead.
