Re: [Kernel][30/01][N7100 N7105 R950] Perseus

Hi,my phone is very hot upside of display when i recharge it...and now i'm thinking it can because of perseus kernel 32?
[Galaxy Note II Original Android Development] yahyoh:
no!!
[Galaxy Note II Original Android Development] themichael:
Made the move to deadline io scheduler. I could be wrong since I don't really have a qualified, technical backing but it seems as if row assumes to much of the way you use your phone.
[Galaxy Note II Original Android Development] cobraboy85:
Re: [Kernel][30/01][N7100 N7105 R950] Perseus

Row is terrible. Don't use it. Deadline and noop will provide the best performance
[Galaxy Note II Original Android Development] frankcilo:
After some tests and some flash of few rom, I come back to v31.2 because v32 not go in deepsleep when charging, and remains even at maximum frequency. I have tried both with the usb charger and AC, and all is well with V31.2
[Galaxy Note II Original Android Development] opasha:
can anyone else chime in on this? is this better or is it better to leave the defaults alone and just change the SDP input current to 900mA and the charge current to 800mA for faster charging? i believe sdp would only be for usb 3.0 at 900 mA from what i asked in another thread and read. what's the best way to get optimal charging without negative effects. thank you :)
[Galaxy Note II Original Android Development] CitizenLee:
I can't seem replicate that with v32.1. Freqs seem normal.

What are you using to check if it has gone into deep sleep?
[Galaxy Note II Original Android Development] WarlockLord:
Re: [Kernel][30/01][N7100 N7105 R950] Perseus

The gcc app confirms a 35% decrease in wireless charging rate on 32.1. I have reverted to 31.2
[Galaxy Note II Original Android Development] Evermind10:
Yup, I use deadline for internal and noop for my sd card. Row places a priority of reading over writing, so in some instances where you have to do both, your phone will face noticeable lag.
[Galaxy Note II Original Android Development] opasha:
how's your phone holding up? no one answered my questions so i ended up just upping the 475's to 900 and 800 as per advice of someone for usb charging. for your wall cable charging, is the 2000 mA working fine for you? any noticeable effects like less battery life overall due to quicker charging? how about heat? thanks

i'm having some slight issues here, i'm using this kernel and overclock my cpu to 1800mhz/1250mV, but my benchmark scores are low, I use stweaks to oc my cpu. i even use setcpu but nothings change..still my benchmark scores are low. I'm using quadrant and antutu benchmarks.

Did i do something wrong.

[Galaxy Note II Original Android Development] nameejokerx:
Sometimes benchmark actually not showing the real life performance of your phone.

Benchmark depend on tweak, usage, app install so basically you can't really depends on benchmark.

If you are really benchmark oriented, install a new rom and kernel with fully wiped, don't install any app and run benchmark.

U might get higher score.
[Galaxy Note II Original Android Development] MonteCarloDos:
I see, i thought benchmarks show the actual performance of my phone, but anyway though, i'm still using this kernel because it has an amazing battery management. If i only use my phone like, making calls, receiving emails and minor stuff, I will have 30%+ battery life 2 days worth of usage. While if I play games, music and other heavy stuff, I got like 20%+ battery life on 1 day of usage. :good:

Re: [Kernel][30/01][N7100 N7105 R950] Perseus

Make sure the governor is set to performance, not the default pegasusq, before running benchmarks

[Galaxy Note II Original Android Development] cobraboy85:
Re: [Kernel][30/01][N7100 N7105 R950] Perseus

This is actually not the case. Your device shouldn't slow down simply due to having more apps installed or being on a "fresh" ROM. One of the biggest factors in determining variation in quadrant scores are a few main things... among many...

The first and foremost is without a doubt your IO performance. They can go from very high numbers to very low numbers (and this is real overall performance, and not just some dumb test) based solely on what IO scheduler you choose to use. Honestly, and people will argue about this forever, the best two for these devices are deadline and noop. SIO is very good as well. Remember that your IO portion of tests are also based on your SD card. So if you have a large capacity card, rated around class 4 or so, it will have a negative effect on your overall score in quadrant. And I'll say this, use quadrant, and any other benchmark app to benchmark YOUR OWN device. Get an idea of where YOURS performs, not yours compared to others. Because somebody else using a small SD card rated at very high r/w speeds will blow away the IO portion of the test by a margin better than you.

The second here to take into consideration is your CPU governor combined with your IO scheduler. I personally do like the pegasusq governor when tuned properly for my performance-oriented liking, or interactive. Interactive is a battery hog on this device however because all 4 cores remain active at all times. If you aren't concerned about battery, try interactive and noop, and set the go_hispeed_load value to 75

Otherwise stick with pegasusq, and simply adjust your up threshold value to 70, your up threshold at min freq to 45, and your up threshold at fast down to 60. And use deadline for your IO.

You will feel a performance boost.

---------- Post added at 01:36 AM ---------- Previous post was at 01:34 AM ----------

You can get "performance-like" response from pegasus if you tune it properly. I see no point in measuring a benchmark based upon settings you are not going to use on a day to day basis. Otherwise you are just doing it purely for number.

I want to know how it performs all the time. Not just when running some benchmark.
[Galaxy Note II Original Android Development] Evermind10:
nope, no decrease in battery life. i'm still able to use it up to 6hrs of on screen time. the heat only comes when i'm charging, it gets up to 40deg celsius. but i usually leave it on the my floor to let the heat dissipate to the cooler flooring. the charger that came with the phone also stopped hissing during the charge.

---------- Post added at 05:53 PM ---------- Previous post was at 05:45 PM ----------

this would increase battery drainage. of course, that is the trade off for better performace since you are ramping up the cpu processing speed.
[Galaxy Note II Original Android Development] cobraboy85:
Re: [Kernel][30/01][N7100 N7105 R950] Perseus

This is true, but my experience has been that it is a very small and trivial penalty in battery life. I have never really noticed it. You might see a tiny bit of extra drain, but it will be very minimal. Not like you are all the sudden going to have to carry your charger with you everywhere.

The trade off of an aggressive yet efficient system is worth it. And if done properly, and the proper balance is found to get the right kind of snappy response when it is called for, can even be beneficial to your battery life.

Example... right now I am looking at just over 6 hours of screen on time with some very aggressive gaming throughout the day, clocked at 2ghz, and the settings I just recommended. Battery is at 17% and I'm looking at around 16 hours since I unplugged it. GPS, sync, all the junk running in the background. That is impressive if you ask me by anybody's standards
[Galaxy Note II Original Android Development] liquidguru:
I totally agree. I use pegasusq and am very happy with it's balance. However, if I run AnTuTu on pegasusq I get a score of around 9000 (less than an SII), on performance I get double that.

I don't understand why that should be, as pegasusq meets my needs without slowing my phone, but it's a big difference

Edit: I've just looked closely at my STweak settings and many of them were very very different to the default values listed. When I hit the 'reset to default' none of them did. I've manually edited them to the default setting now. Is this normal? I have SetCPU installed. Does this interfere with STweak?
[Galaxy Note II Original Android Development] cobraboy85:
Re: [Kernel][30/01][N7100 N7105 R950] Perseus

If you are using stweaks you don't need set CPU. And something is definitely up if you are seeing 9k on antutu. I have never seen less than 19k on this device.

Change your IO schedulers to deadline. row is not optimal for a device that needs to write data as well as write it. Overall performance suffers with "read over write" bias.
[Galaxy Note II Original Android Development] liquidguru:
It seems like something has somehow got very messed up in my STweaks. I've reset the values manually now and things seen better.
[Galaxy Note II Original Android Development] Evermind10:
I didn't say it is a bad thing. Haha. I in fact I have adjusted my Settings to what you recommended. Too see if your settings meet my daily needs.
[Galaxy Note II Original Android Development] cobraboy85:
Re: [Kernel][30/01][N7100 N7105 R950] Perseus

You'll feel a slight boost in performance without any noticeable loss in battery. There are other small things I do throughout the entire ROM and specifically regarding the processor, GPU and IO scheduler. But try that out for now. And seriously, don't use ROW. It is a terrible implementation for these devices. noop and deadline are used by Google for android for a reason - all around performance. The logic of the two schedulers is more ideal for an android platform.

no deepsleep under charging

with v32.1, when under charging, does not go into DeepSleep, while with v 31.2 goes into DeepSleep!

Re: [Kernel][30/01][N7100 N7105 R950] Perseus

I actually use the almost same settings, mine is just a little more relaxed than your values to ensure that the battery life trade off is minimal to none at all..Ive also fiddled with other settings in the hot plug and scaling settings.. It's a little tricky though.. But overall the settings that you suggested will surely give performance boost

Any plans of incorporating Wolfon audio tweaks (like in neak kernel) ?? Perseus is superior in every way, especially with 32.1 (T889), but neak's implementation of wolfon audio is simply superb. Even at high gains, audio doesn't crack. Would love to see wolfson in perseus.

Thanks for your hard work dude!

ps. Not switching to neak since battery life on 32.1 is mind boggling .
[Galaxy Note II Original Android Development] CitizenLee:
Perseus uses ScoobyDooSound. "Wolsfon" is the actual chip type and if you check the Audio tab in STweaks you can change some options to get the best out of it. ;)
[Galaxy Note II Original Android Development] teshxx:
lol Let me rephrase...Is there any way to incorporate the audio tweaks like in neak. I know Wolfson is a chipset and I am aware you can tweak it under Audio in stweaks. The issue here is that if I change the speaker amplification to 1, it sounds fine, but at 2 it get distorted at higher volumes. In neak the audio still stays crystal clear.

I hope that clears it up.
[Galaxy Note II Original Android Development] CitizenLee:
Ah, that clears it up perfectly! Makes perfect sense now :)

I believe NEAK uses Boeffla Sound by AndiP right? If so I'm pretty sure Andrei said he'd look into it a few weeks ago but that was the last I've seen any mention of it... although I could easily have missed any new posts on the subject.

Hopefully Andrei will appear and give us the latest info ;)

[Galaxy Note II Original Android Development] shaolin95:
Speed does not kill CPUs, voltages and heat do. Since we are not pushing anything higher than what is safe for the cpu or less , I say you are safe.

[Galaxy Note II Original Android Development] shaolin95:
I know they got it to 2Ghz before but the problem is they have not figured out how to let us manage the voltage in AS kernel so I think he stopped at 1.920 for now until that is sorted. I am sure we can run 1.920 with less than it is using now and based on how many people can run it, I see 2Ghz having a very good chance for a decent percentage of users but that is just my guesstimate :)

[Galaxy Note II Original Android Development] xantrk:
Im using wanamlite 2.8 , just social network (facebook,whatsapp etc) . In default settings , i have same problems , Im trying to lower up threshold , increase cpu up rate, icrease freq for responsiveness , but no luck to get smoothness.

Im triying with default settings now , home screen not always laggy but sometimes lags also sometimes i cant see the animation that when you press the apps button.

Then now im in settings , its just jerky while scrolling :\

Edit: I hope to have power saving on , but unfortunately :( I will try to record a video if these stutters and lags can seen.

What a ridiculously stupid claim! I bet you wouldn't notice the speed difference in a blind test. You're also better off setting the governor settings to something more relaxed in that case.

I'll be eventually releasing higher clocks when they will be reasonably achieved, and that means ABB control. In the meantime you're welcome to stay on other kernels or use the by now outdated 2GHz kernel posted in the early pages of this thread.

[Galaxy Note II Original Android Development] i900frenchaddict:
Well, when I do tests on Fpse, pushing my max CPU speed up to 1.8ghz instead of my usual 1.6ghz sometimes brings 5 Frames Per Second more for some games (ex: Tekken 3 with openGL plugin is 45fps at 1.6ghz and 50 at 1.8ghz. My game is PAL version, so 50fps is the maximum)

That's weird indeed, on my other devices (HD2, HTC Sensation and HTC OneX), 200mhz more don't make any visible difference.

This +5fps difference is each time and immediatly visible. The ratio is logical: +5fps out of 50fps Vs +200mhz out of 1800mhz

But I must conceed that's the only exception, for all the rest (UI, apps, games), I can't see a real difference, and benchmarks are sometimes the same at 1.6 or 1.8ghz

Finally, I've sticked to your kernel for many weeks because it's the most innovative in my opinion and 1.8ghz is enough for now

Great work!
[Galaxy Note II Original Android Development] sephkateno:
Actually I don't know about you but in some emulators which are to this point very "young" in development even if I had 2ghz of cpu speed it would still be not fast enough so yes 1920 mhz instead of 1800 mhz has some fps boost in perfomance is that so stupid? Try it yourself I'm no dev and don't claim to be one but I didn't insulted you in any way.In any case sorry if I offended you and your work Andrei. Oh and the emulators are for psp and nds.

nope. you can monitor it with a battery app like "battery" and view it's temperature. it usually stays between 75-78 degrees fahrenheit for me. just change sdp input to 900mA and sdp charge to 800mA. i also enabled the dcp input to 2000mA and dcp charge to 1900mA. definitely increases charging speed.

Your wall charger charge at 1800mA. Why would 800mA overheat? The bottleneck of usb charging is on how much output your USB port can provide not what the battery can take.

Re: [Kernel][30/01][N7100 N7105 R950] Perseus

There are usb 2.0 ports that produces 900-1000mA depending on the connected devices on your system.. If all ports are used up, the motherboard will only give 450-500 mA.. Most modern motherboards and laptops give 1000mA.. That's why the other poster only takes 3 hrs(900-1000Ma) to charge his device compared to 4-6 hrs (500mA) using a usb port.

Motion not working after Perseus install

Edit 2: Seems gravity is always affecting the acc meter..go figure :silly: Will do some more testing and see why certain functions don't work.

Edit: I did some self tests and the readings were erratic. Did a calibration and it all works now. However the Accelerometer doesn't work properly. It's showing high ACC Raw data, but the angle is correct.

I'm still running stock 4.1.1, and decided to install my first kernel after the initial root cwm. After having installed the latest Perseus I no longer can use motion. I cannot unlock from lock screen to camera, and i cannot move things by tilting. Why is this? Is it not compatible with 4.1.1, or is it a bug?
