You are saying that you don't have any other phone in your house that has USB C cable 🤔
If I assume that charger as well as data cable is ok then it might be problem with battery calibration. Go to homescreen, press and hold power key till it shuts down and turn on, then plug in charger. And try to drain your battery till its gets switch off. If its problem with battery calibration then giving 3 full charge cycles should recalibrate your battery, but chances of battery calibration issue is very rare for any newly launched ph not stored in switched off condition for prolonged period.
yes bro I did all that. connect/re connect. change sockets. nothing happened. also it charges okay for 60% but after that it just cease charging on it's own. then I have to do whole charade of connecting/disconnecting/ reconnecting. changing ports etc, then it'll charge for sometime then stop again
