[Galaxy S III Android Development] axetilen:
1/ samsung push: nothing happens if you dont use any samsung apps like chatOn. opne play store and search for samsung push service -> read the description and you will see -> reduce a lot of wakelocks according to your BBS

2/ Greenify play store: you may lose autoupdate but they will be triggered again when play service is activated -> you dont lose any update but it is slower than normal. I recommend you to turn off autoupdate in playstore settings and update apps manually. Autoupdate is reported to consume Ram and battery -> this will reduce a lot of wakelocks (A LOT)

google play service was updated to v4.1 and claimed to save a lot of battery. I dont care, I turned it off :)

3/ Only use 3G when you need to surf the web. Use 2G when you put your phone in the pocket or only when you use IM chat apps like viber and whatsapp. Im fine with these

also try intelli3G. I have never used it but I think it helps

4/ using lowest brightness is very good. Use autobrightness at the lowest level in outdoor conditions

5/ DONT USE PegasusQ with AFTR+LPA -> your phone cant reach deepsleep state

If Im not mistaken, I read this from somewhere that if you use AFTR+LPA, your phone can only go to deepsleep only when there is 1 core running. If there are 2 cores running, it prevents your phone to go to deepsleep

usually, pegasusQ keeps 2 cores running and maybe switches off 1 core after a period of time (I dont know when) -> goes against AFTR+LPA

pegasusQ battery saving & pegasusQplus battery (maybe there are some more but I dont remember) are the only governors that switch off the 2nd core quite fast so if you use these, it's fine but in general, I dont recommend to use pegasus with AFTR+LPA

I use zzmoove yank battery extreme instead. If I wanna play games, I use pegasusQ battery

with exactly the same configurations, PegasusQ battery seems to be slower and makes my phone hotter than zzmoove yank battery (dont know why). It got 44*C, never happens with zzmoove. Both are set at 1.2ghz, same GPU, same UV

I monitored the behaviours of these. However, because the overheat, I cannot go with pegasusQ battery

6/ turn off all sounds and effects and see how it goes. In the older versions of touchwiz, they are reported as the culprit of using too much ram and causes too many wakelocks. I dont know sammy do fix this or not because I always turn them off from the beginning

I dont recommend using CFQ with extSdCard because according to a credible source - thanks droidphile:

it might causes problems with mediascanner. I prefer SIO and ZEN. In fact, changing these in the extsdcard doesnt bring noticeable difference, quite minor in my experience because we dont always use sdcard and the speed of this is limited. You may see noticeable improvement with internal storage

7/ you should consider the list of frozen apps. you will have more free ram because useless apps are removed. They wont consume ram and battery and cause wakelocks.

if you have a look at my screenshots, you can see, AndroidOS only took 4% -> I was surprised also, couldnt believe that. I only have ~2 minutes of wakelock in 11 hours of deepsleep. I use facebook + fb messenger + viber, they cause wakelocks. I dont greenify them
