Wanted: Battery Shamans

I'm pretty happy with the battery life of the Blackberry Priv. It is not that I travel without a backup power bank, but generally I do not run into troubles. But from time to time the phone can drain a lot of juice even before lunch, just doing nothing.

Chasing the battery draining ghosts I installed an app called GServiceFix and it seems to have cured the disease. Which is scary...

Scary, because I've had this problem on other phones and other versions of Android. It probably started with the LG G3 running KitKat and continued on the G3 upgraded to Lollipop, was present on the Priv running Lollipop and now has been noticed from time to time after upgrading the Priv to Marshmallow. A strange plague rooted somewhere deep in the Android OS, popular enough that someone takes an effort to build an app that cures it.

But looking around I'm finding more questions than answers about what the GServiceFix really does and why the fix, proven working by many, has not found its way into the official Google Play Services code base?

Controlling battery drain is probably one of the most challenging tasks operating systems have today. Apple has done a good job with that on OSX (because it controls the hardware fully) but even failed to protect iOS devices against power draining bugs in other apps (like Facebook). Windows PC have been suffering from this for ages. Ubuntu power management (or the lack of it) was why I reverted back to OSX on a MacBook Air. And now Android, even in what seems like a well controlled Blackberry distribution, has this problem too. The problems, for average users, are like ghosts, haunting their experience. Fortunately there are shamans who can chase them away. But is this really how consumer software/hardware products should work?
