Heya everyone, I Have an issue with my iPhone 4: Have you noticed that when you turn on WiFi the battery starts draining much faster? Well during usual business I noticed that even though I had the WiFi turned off, the battery would still drain as if it was on. I have checked for other battery drainers and nothing is unusual so that has to be the only explanation. Plus, I once saw the battery draining fast and switched the WiFi on and back off and battery went back to normal. The next time I switched the WiFi on (and after finishing business, off) it kept on draining the battery as if it was on. Any ideas?
