My USB cable is broken within less than 2 weeks
How to get replacement or warranty coverage for USB cable .
iPhone 11 Pro Max, iOS 13
Srikanth,
Not sure where you are located however here in the US we just take the Apple Supplied cable to the Apple Store and they exchange it if the cable damage was caused with regular normal usage and that it was bought along with the new iPhone. Try that if you can.
