suspend_backoff wakelock killing my battery since 4.3
I've had my N4 since the day it was released and the battery has been generally acceptable.....until I upgraded to 4.3 (stock, rooted).
BetterBatteryStats is indicating the suspend_backoff wakelock is rampant. WakelockDetector is showing I'm only getting 20% deep sleep on days I'm only lightly using my phone. On Android's Battery screen "Android OS" is listed as the top culprit, consuming 40% or more of the total battery.
Google/XDA searches indicate suspend_backoff is related to Chrome, but I'm convinced this is somehow a wifi connectivity problem as this wakelock ONLY happens when connected to my work wifi. On the weekends when not working my battery is fine and I don't see suspend_backoff. If I don't connect to my work wifi while at work suspend_backoff does not show up at all and I'm deep sleeping at 80%.
Unfortunately at work I don't have the capability of configuring/swapping wifi hardware/settings, so I'm limited to finding a solution on my end. Hopefully the solution isn't to have to sit on mobile data all day long instead of connecting to my work wifi.
