Thats why i tune my own governor so a simple screen touch doesn't waste juice boosting to 1ghz. You don't need aggressive power savings like i have setup but setting it up a bit more conservative would help that. Hopefully it all turns out like that. What i do know is once i started keeping entropy from depleting my modern hardware which i had slight lag due to low mhz from aggressive power saving on the governor, I noticed the lag was gone. There was added latency before that does not exist now and ive been really tinkering to see why. Truly on my phone monitoring entropy unmodified by wakeup threshold and seeder or with one or the other entropy is definitely used by more than the big development from google could care to admit.

- Every on screen item and screen press or drag of an item or rows of icons uses up entropy, try it

- Vold a function of i/o as well as others use entropy

- starting a process uses entropy

-secure wifi uses it

So we already know stock entropy can be used up faster than its refilled in fact if enough of the above and it could use more than the standard max which is less than 200... (64*3) before its depleted never reaching a full entropy pool of 4096.

Once Android is patched we may see how android should have been long ago.

For now android to remove lag has really had to crank mhz or cores like you guys are getting at... now if this all gets addressed even with Exynos 5 Octa on the way we wont need the shear power to still stay smooth and that truly is what we are seeing here. What we all thought was lag from cpu mhz idling to low a good portion for many devices and even up to 4.2.1 on the latest hardware was all caused by entropy for a lot of us. Excluding lag from i/o, slow internet speed or slow processor for some, adddressing how many point out that truly lag we experience can and does come from many combined factors and latencies. I think the OP needs a pat on the back for bringing to light a subtle issue flaw and source of a repeatable source of lag. Plus low and behold its even improved some modern hardware on the latest android OS. Could be custom kernels, roms or add on launchers and so much more in ways they function some how draw more on entropy. Some have reported oh i launched this i benched that i played this and stock my entropy never drops and those same ones will try the app and point out the same, with the next statement this dont work. It just seems some random combos of hardware, os apps kernels and customization plus mods can take more or less entropy on others setups or even none at all. So we will always see half with no benefit and the other with.

Perhaps research should be done thoroughly on every action or command that draws on entropy and in future os and app design be optimjzed that unless it really is necessary it does not use entropy and furthermore we all should hope that in general the whole issue this addresses is actually fixed in future updates or OS versions, because if we or some are seeing any improvements (which we are) on the latest hardware/software then it seriously needs to be addressed aand not claimed to be a non issue for modern 4.0+ devices... if that was the case there would be 0 improvement on any of them at all.
