I am using a iphone charger for this
its rated at 1A

It may be "rated 1A", but this behaviour is typical for a supply that cannot provide enough power, the moment it is asked to do so the output voltage collapses, and reset the PI.
It could be that the "USB power cable" is too long, and/or too thin, and causes too much energy loss.

Try another power supply.

I think laptops only supply 0.5 amps per USB port. You could try one of those Y cables which are sometimes used to power usb drives from two usb ports.

Best to try from a powered USB hub if you can get your hands on one.

The problem was my usb cable

As good as it gets.
