Kevin Pietersen has since taken over the reins and guided England to a 20-run win in the first of five one-day internationals against South Africa.
Collingwood insists he is now happy to concentrate on his own performance as the added responsibility had been taking its toll.
"I just found the captaincy was added responsibility which was very draining," he said. "The thing was it was taking the form away in Test cricket and that was the last thing I wanted it to do.
"I'm very much looking forward to it," he added. "It's great coming back into the ranks and concentrating on your own job.
"Hopefully I will be scoring big runs for England."
