Hi all, After noticing my battery was draining quickly, and then after reading this thread, I installed Android System Info to see what was draining my battery so fast. I notice that whenever I would turn on WiFi, the phone will never go to sleep , regardless of what I set the WiFi sleep policy to. After turning off WiFi, the battery still drains heavily. The WiFi will shut off after 15mins (if you set it to "When screen turns off" or "never when plugged in"). However it seems to keep the CPU on causing it to drain down the battery. It would seem that whenever WiFi is enabled, the Android system process creates a partial wakelock that does not go away even if you turn off WiFi. The only way to resolve this is by powering off or rebooting the phone. You can verify this in Android System Info by going into Battery-History-Other Usage-Partial Wake usage to see how much time the "Android System" process holding a partial wake. I even did a factory reset on the device; and it is still happening so it doesn't appear to be any app that caused the issue. As I said, it works fine as long as I don't enable WiFi. I already know of two users having this issue, but I'm wondering if folks having battery problems are going through this as well. Is anyone else having similar issues after using WiFi? I'm hoping someone will be able to identify what exactly is putting the wakelock on and we'll be able to find a fix for it. Other than not using WiFi at all or rebooting the phone after using Wifi. Any help would be greatly appreciated.
