[Android General] Rakuu:
The wakelock is precache though not the browser itself.

Now before we even get to the partials we see screen on time is 23 minutes, screen off wake time is 47, and PowerManagerService.WakeLocks is 55, so while some of it can be attributed to the screen being on, at least some of the partial wakelocks are occurring and keeping the phone awake with the screen off, and seeing as precache is the top one, I would assume this to be the first one to tackle.
