iPhone 16 Pro not turning on after charging

My first 16pro did exactly the same thing at 6 days old, purchased through Apple online Sydney, Australia on 13 February. The Hornsby store NSW confirmed this and gave me a new one.

Now I’m on holiday in Canada and the exact same issue has occurred. Charged overnight and will not power on 3 weeks after being in my possession.
