When I bumped into this thread which listed a version of Google Play Services, version 4.4.52; I immediately updated mine which was suffering from extreme wakelocks (I was on 4.3.25).
Here is my phone running the latest version
After installing the new package I went to bed, hoping to wake up in the morning to an improved and reduced battery use. Boy was I wrong!
My phone was awake for the entire 9 hours while I slept!
Look at the awake bar, and notice how it never went into deep sleep! Fortunately, after a couple of reboots my phone was able to enter deep sleep. But, compared to numerous screen shots of other users' battery stats, my phone displays significantly more awake periods.
Keep in mind I have factory reset 3 times now, and the wakelocks continue to occur and plague my existence, resulting in furious vain attempts at finding a fix. The only way to prevent such wakelocks and idle battery drain for me was to disable location services, hence crippling Google Now and other location features.
Does anyone else suffer from poor battery life despite disabling all gimmicky features such as hand motions as well as bloatware?
Have you been able to develop a solution?
