iPhone 14 pro malfunction

I bought a new iPhone 14 pro 1.5 months ago. The day before yesterday, after the phone completely sat down, it did not turn on for a long time. It turned on only after standing on the charge for 30-40 minutes. The screen did not react in any way, it was not even visible that it was charging. After switching on, the percentage of charging was only 4%. today the situation is similar, only the phone does not turn on at all and does not respond. tried to reboot but nothing helps
