Did somebody notice a major power drain issue after iOS5 upgrade on iPhone4? Last night at midnight, it was ~90% charged. In the morning, it was 37% charged. By noon, it was dead. I didn't make even 1 call during this time. Connected to Wi-Fi at home and strong 3G signal. Bluetooth is off, location services are off, all that stuff. The same phone's battery would last for 40 hours with my normal usage with IOS 4.3.5. Anybody knows if any specific feature of iOS5 is causing this battery drain?


iPhone 4, iOS 5
