I have not read anything about auto scaling being a problem and I have not looked for the post so that being said, my experience with XCPUScalar is that when forced to the higher 520 I use more battery, now keep in mind I am using my 6700 all the time it almost never sits more than 10 or 15 minutes and I am turning it on, I think this has to do with the XCPUScalar auto scaling faster than the internal device scalar when the device is on. Dose that make seance? Also I have had issues with my 6700 freezing up more often when locked at 520, I never use 624 because of the screen noise and constant lockups on my device setup. In as far as weather scaling is the correct term or not, what I have read leans my opinion towards what Rufis is saying, so IMHO find the speed where you get the best results for you and go with it.
