My iPhone wont turn on
Hello, my iPhone XS wont turn on and I was wondering if anyone could help. Yesterday when I went to sleep my phone was at 2% so I plugged it in and went to sleep assuming that when I'd wake up it'd be fully charged. Although when I woke up today and tried to turn it on, it didn't. I've plugged it in and tried to charge it using 3 different chargers but nothing works. It doesn't show the red battery when I plug it in to charge it so I'm not sure if it's dead. I also tried to power it back on in case it was just turned off but that also didn't work. If you know how to fix this problem please, please, please, help me. Thank you.
iPhone XS, iOS 13
