"I hope to return to my best in this series... and it will be good if it happens before the World Cup," Azam told reporters on Monday.
The lean patch saw Azam dethroned as the world's top-rated T20I batsman, after ruling the rankings for 1,155 days, relinquishing the title to his opening partner Mohammad Rizwan last week.
Azam, who is Pakistan's top T20I run-getter with 2,754 runs in 80 games, said he keeps things simple while batting.
"I think less about failures when going through a bad patch," said Azam. "As a batsman your focus is to do your best to regain your form and it would be great to do that before the World Cup."
Azam was the highest scorer in last year's Twenty20 World Cup held in the United Arab Emirates, with 303 runs in a tournament where Pakistan crashed out in the semi-finals.
Azam said the England series was a "big occasion".
"Obviously they have come to Pakistan after 17 years so it's a big series and will help us build us towards the World Cup so all the players will utilise this," he said.
The matches will be held in Karachi (22, 23, 25 September) and in Lahore (28, 30 September and 2 October).
