The CPU Governors - Samsung Galaxy S II Plus

Hey guys. Can somebody please explain me shortly how the CPU governors are and what are their features?
I use my phone for daily-use purposes like browsing the internet, playing games, and listening to music. Now what is the best choice for me to use? and by the way I'm using the mosh kernel.
Many thanks in advance...

Overclock

First of all, I've done some searching and haven't found enough information about overclock on HTC ChaCha (Status), that's why I'm starting this thread.
I've bought my HTC ChaCha, but I still don't have it in hand. But for all of you that are already playing with it, how is overclock?
GSM Arena shows it has 800MHz, but is it enough? Have any of you experienced some sluggishness or "small hiccups"?
And for you that already overclocked it, how much MHz have you reached without rebooting for overheat?
Well, it depends.
Generally, I'd say, it's enough, but there are some moments, when You can feel, the CPU is busy.
If You want to watch DivX movies, it's definitely NOT enough.
If You look at the battery life, it's too high.
We would need an OC/UV kernel, but I didn't find any yet (and I don't know, how to create one).
as for overclock there is not a need. u'll just need a memory free apps(recommend memory booster free) when u feels lag as the ram runs low. the 800mhz processor in this phone is working well.
as for Divx i'm not sure but i use Mobo player for videos(with codec*free) from market.
you could try MX Videos player free in the market for Divx videos as i do not have any divx format videos to try it out.

If you say there's not a need I'll believe (after all, you own the phone, I'm still waiting for mine), but how do you use your phone? Do you watch online videos, do you play games that demand a good phone hardware? How does Angry Birds play on ChaCha? And what's the score on Quadrant Benchmark?
talking about angry bird... it make me wanna laugh... when u try zoom out the birdie look like sesame seeds... lols others games i have not try due to internal memory running low... not till my xtc clip arrives...
online video is "not possible" as the chacha come with built in flash player lite. maybe youtube will just fine. some website u'll not able to play the videos. i tried install flash player 11 but no effect on it.(u won't be able to see any flash player apps in market too)
Played - They need to be fed. Runs ok 'till it has to zoom out - a bit sluggish then but otherwise it runs perfectly.
Pool Break Pro (or something like that) - runs great
Some game with a robot that has to get some keys (forgot the name) - runs great also

hahaha this one made me laugh!
well, then I say we can expect some lag depending on the game, but I think it's normal. but I still believe a overclock would help.
We need a custom kernel for that.

[Q] Deep sleep with music playing?

This might be incredibly stupid, but does anyone know if it's possible to have your phone deep sleep while playing music through headphones? Because it sticks at min freq and kinda eats up battery, regardless of governor or I/O

Sry to unearth that thread, but i had the same question and didn't found an answer here on xda - so i checked it myself.
And the answer is yes, it is possible, but to my knowledge there aren't many music players that support this.
If the sceen is off they buffer the blayback and let the CPU go to sleep and occasionally wake it up to rebuffer.
CPU is in deep sleep for 60..80+ % of the time.
Music players that let the cpu deep sleep (to my knowledge):
- clean music player
- es player (part of es file explorer)
Music players that idle at min frequency or higher and dont allow deep sleep:
google music player, playerpro, neutron, shuttle, nexmusic, n7player, poweramp
I've checked the deep sleep behavior of the above mentioned players with CPU Spy v0.40 on Stock Nexus 5.
The downside is that costum Kernels can cause the playback to stutter, just stop and/or other things.
I don't know exactly why but my quess is that happens because of a too low frequency in the time the cpu is awake - to raise that may help.
Or its maybe because of too agressive governors that force the cpu to early back to deep sleep.
It would be interesting to see if anyone else had made similar observations, found other music players that support deep sleep of the cpu.

Hi,
The solution is to stop the media player after a certain time. If you want to sleep with music we have a tool that allows you to set the duration for the player and a gradual reduction of volume at the end. So it will stop the player and let the phone to go to deep sleep mode

The goal is not to go to sleep while hearing music and stopping the music when you are asleep.
The goal is that the music is playing while the cpu of your phone can go to the "deep sleep"-state and in consequence to save battery while playing music.

I understand that but what i mean is that playing music needs cpu to run in normal mode, I don't think that it's possible with android coding and i think that you don't have to worry about that as your screen will go off after a certain time and as you know the screen is consuming more than 95%
That was also my thought ... But some player like the above mentioned display this behavior of letting the cpu go into deep sleep state on nexus 5 with android 4.4. The playback works fine for a while but then just stops and/or crashes utterly. Seems to be a bug with the new android but non the less the playback works for a while (up to 5 to 10 min)
The CPU is for 50 to 75 % of the time in deep sleep
Would be interesting to see an player who can make usage of that behavior/bug. There is always need for more battery life

That's right but I don't think that as app developers, we have that control. All what we can use is wake lock to wake up the device partially or fully when it's locked or to keep screen on, but for media player it's handled by the system so I think that this optimization is done by mobile constructors. You can use batterystats app to keep track of wake locks to detect big consumers and stop them (or remove them) to keep your battery charged for long

I'd like to bump this thread. I'm REALLY interested in such music player that would allow deep sleep during playbackplayback. We now have high memory devices, some with whooping 4gb of ram that could hold the entire library of most casual users. I really do hope there actually is a player that would simply load like 20 tracks that are in the Playlist to ram and then simply let it go with minimal cpu usage thus hopefully allowing for deep sleep. I did see a something interesting on my windows pc. Few years ago, when I started using foobar2000 I got a BSOD, irrelevant to the player, but I was listening to music and after a BSOD it actually kept playing for quite long even though the os was on halt completely. Thanks to the long 30s buffer I set in foobar2000.
I think this concept COULD actually work on our android devices. Please do correct me if I'm wrong. If there's already such player then please post a link. I'll be glad to try it. I'm a music addict so that would help me.
I did try clean music player, but I couldn't find a way to play all tracks from one directory including it's subdirectories. All I care about is shuffle all tracks from one directory including it's subdirectories and of course ability to use a equalizer.

Second bump. I would definitely agree with the need of an app like this*! Has anyone found anything?

I haven't heard about any. I've had an idea of loading tracks in playlists into a single long track, then loading them to ram and that might allow to play them without waking the device, but that requires a certain level of skill.
Worth bumping up in 2022?
Maybe?
(Also looking if this can be solved for Spotify on bluetooth headphones).
I don't know why this excellent feature didn't get widespread acceptance. Other than Nexus 5, I only know the Xiaomi Redmi 3s which supported this feature that too only in Android 6 (stock MIUI and LOS 13). In all the Android versions till A12 which I have used it didn't work.
P.S. Unrelated but Xiaomi Redmi Note 10 Pro and Poco F4 can enter Deep Sleep while serving as a hotspot, at least in MIUI, but not during audio playback

[Q] Music Stuttering with almost every music player

I am experiencing some - a little bit annoying - bugs in music playing, and i hope someone could help me..
I am using stock rom, phone is rooted.
Actually I am using poweramp as main music player (which the better one for solving part of my issues) with the following sound andvanced settings:
-no dvc
- buffer size +750
-Thread Audio: Maximal
and music still stutters everytime my phone locks the screen or randomly every 2-3 minutes (i don't know the exact name of the problem, but it's the same as when you're listening to streaming music and it has some buffer problems, it stops for a nanosecond, but you can clearly hear it)
I tried also different options, as it looks like it could be a ram processing problem, by disabling all unnecessary applications i didn't use, sense included (Using Apex right now). Disabling beats doesn't change a lot (and I bought this phone also because of Beats Audio, I won't turn it off)
I tried also some of the custom roms here on the forum but nothing changed... The biggest "ram-eating" applications i have always on are whatsapp and Fb messenger, i wouldn't think it's because of them.
I tried a lot of combinations, this one looks like the better one (music stutters only sometimes).
This problem doesn't exist only with stock music player - that means there must be a way to solve this - but i don't use it because it lacks of a lot of things.
Has anybody ever experienced this problem? Any help?
If you are rooted, you can give another kernel a try.
Maybe stock, oc kernel like Stockbeats Kernel.
Don't forget the backup before.

I already tried the Flashbeats ROM without success, did it use this kernel?

Flashbeats rom use Flashbeats kernel, Stockbeats kernel is a bit different to that. So maybe try and see if it helps.
I installed it buy still stuttering when i open browser while listening to music or turn on wifi
Maybe try to change oc, govenor and/or I/O scheduler.
If this also don't help, i have no idea atm.

I have the same stuttering problem with stock JB rom and Poweramp and Google Play Music.
I haven't managed to find out cause or solution. Basically any third party music player is practically unusable.
Stock music player works perfectly, also to my ear with superior music quality, but not having gapless playback in 2013 is unacceptable. It's probably the only serious defect of the phone.

Exactly the same... and I am still hoping someone will find a solution i am no expert, but maybe the fact that with stock music player everything's fine means something...

I am using trickster mod to see if something changes, can you help me with the settings? I don't know what they mean, and where it would be affecting the music stutter..
Right now its settings are:
TCP congestion : cubic
Read Ahead Buffer size: 128
Scheduler: cfq
Block frequency: YES min 384000 max 1566000
Governor: ondemand (changed into performance a couple of times)
MP Decision OFF
Multicore energy saver:1
GPU -Governor: Ondemand
Max frequency 400

Sorry, i don't use Trickster mod. There must somebody else that tell you whats going on.
Hi.
FYI on stock kernel and rom, I tried winamp and there definitely was some stuttering.
On spotify or stock music player no problem at all though.
This behavior doesn't change after the update to Android 4.2. Play Music and Beyondpod still have the stuttering, only the stock music app works fine.
It is also becoming a more significant problem because not only the stock app does not support gapless reproduction, but also when I switched to the Google Now launcher (which I like better than Sense 5) I can no longer use the music widget.

I solved with playerpro & DSP pack, setting audio buffer to maximum and audio priority to maximum + it supports gapless. I have tried millions of possibilities (kernels, deleting stock apps etc.) but this is the only one which seems to be working in my case. Poweramp stutters less than google play music but stutters anyway (even with high audio priority etc)
You can't get the music widget of the stock music player because it's only a sense widget works only on the sense launcher, unfortunately

1.music player ur using
2.mods ur using I.e v4a,Dolby etc
3.custom kernel to more enhance the music
4.ur configurations with ur mods or inbuilt music player customization
(It can be profiles of ur mods like for v4a or just share screenshots)
Here is mine setup,
1.Samsung stock with soundalive
2.nothing
3.voltaqe kernel Wolfson sound tuned by me
4.uploading screenshots
Now its ur turn, share ur thoughts so that we can also try.
Have a nice day :good:

Scheduler Tweaking ?

Hi group,
is there may be a way to tweak the scheduler of a routed android?
Since the stucking maps on the px5 makes the music stutter also may be some tweaking never all cores to one app can improve the problem.
