Apple’s (AAPL) recent iOS 6.0.2 release had one major purpose: to fix Wi-Fi connection issues. But according to TidBITs and many other iPhone 5 and iPad mini users on Apple’s discussion forums, the update is draining battery life quicker than usual. According to TidBIT’s Michael Cohen and Adam C. Engst, the issue may be related to the updated devices now working harder to scan for Wi-Fi access points. It’s unclear how widespread the battery drain issue is. BGR didn’t notice any unusual battery drainage on one of our iPhone 5s running iOS 6.0.2. This also isn’t the first time Apple’s iOS devices have suffered from battery issues after a software update, and likely won’t be the last.
