Battery life due to Internet

[Jeph0r3]

I was wondering if there was a cab that I could install that would make it so when my phone checks my gmail. That after a determined amount of time, the phone will disconnect from the internet with no data being transferred. My phone checks email like every 4 hours, but if I go in a 1x area and it is connected to internet, the battery life dies rapidly. Thankyou..
