iPhone 6 Plus will not power up

Hello Ilidrian,
I ams sorry to hear that your iPhone doesn't power on. I know that it can be frustrating but let's see if we can get it sorted out.

Take a look at the article below. Go over all the steps in "If your device still won't turn on or start up" to see if it powers on. If it does not, then you will need to contact Apple Support for further assistance.
