Hi sanju249,
Welcome to the Apple Community.
Wondering which iPhone model you are using,
also
which iOS version you are using on your iPhone (latest is iOS 15.5)
and
is this an Apple cable, or another brand...
also
if you have tried using a different cable ... eg borrow a compatible one and see if the problem persists
