Andrei could you please gimme an exemple of the whole table echo for volt_table, because we have 2 values here (frequency and voltage) and not one like in the freq_table, so i'm not sure how to syntax it. I'm still a noobie. ^^

Thanks.
[Galaxy Note II Original Android Development] frankcilo:
ok, I thought it was 90 up and the 10 down. excuse me:good:
[Galaxy Note II Original Android Development] metus666:
Thanks AndreiLux for such an amazing kernel.

Don't give up on the SGN2....We appreciate your work and making mistakes is only human. You are our only custom kernel developer in these forums and it would be a shame to ever see you go.

I set my min gpu to 54 and max to 640. But on reboot its always back to default! !?! :confused: How can I make this save permanently?
[Galaxy Note II Original Android Development] AndreiLux:
echo " 54 640" > /sys/devices/system/gpu/freq_table;

This sets the 54MHz step to 640MHz, doesn't make sense. I don't know what you're trying to do here. After editing the 54MHz step, it doesn't exist anymore so I guess you misunderstood it as you're still editing it afterwards.

echo "54 825mV 640 1138mV" > /sys/devices/system/gpu/volt_table;

This isn't pair-wise echo. Please read my post...

echo "54 825" > /sys/devices/system/gpu/volt_table;

echo "640 1138" > /sys/devices/system/gpu/volt_table;

Is the correct syntax.

echo "90 10" > /sys/devices/system/gpu/thresholds;

echo "640" > /sys/devices/system/gpu/max_freq;

echo "54" > /sys/devices/system/gpu/min_freq;

Above are correct.

Could someone explain me what use it is to undervolt/overclock the GPU? Does it make a bigger difference than uv/oc the CPU?
[Galaxy Note II Original Android Development] Hendrickson:
Thats easy, undervolting can save power and increase battery life, lower GPU frequencies help too. Higher GPU for more performance. If I could only get it to save after reboot :(

[Galaxy Note II Original Android Development] Dan Law 001:
I don't know why even that CPU is set into performance mode and min 1.8 GHZ max 1.8 GHZ, after few minutes of heavy gaming it drops back to lower frequency such as 800, totally out of range. Is this a safety feature that prevents the battery going to hot or some bug?
[Galaxy Note II Original Android Development] antt00:
Cpu protection. If it gets too hot it will step down to 800.
[Galaxy Note II Original Android Development] voyager20021:
Disregard,found the answer.
[Galaxy Note II Original Android Development] Dan Law 001:
Mmm, so what can I do to enjoy high speed CPU without making it very hot? Will undervolting be a good approach? By the way, dated back from the time with the old Atrix 4G the frequency stays the same even that the CPU frequency goes beyond 40C° and there seems no damage to the CPU...
[Galaxy Note II Original Android Development] antt00:
It makes no sense to keep the device fixed at 1.8ghz.
[Galaxy Note II Original Android Development] Dan Law 001:
If you just browse webpages or read emails then there would be no effect on max frequency but if you use apps that require heavy CPU performance then it would be quite obvious to see the differences even when setting a range between 1.7 and 1.8 and 1.8 and 1.8. And you can also run a benchmark test to see the differences.

[Galaxy Note II Original Android Development] FUSIONdev:
Regarding the "lags" issue: it became really frustrating for me when moving fast between apps so I decided to try neak (I choosed it because of audio controls)

Ok: neak is smooth, also with AFR+LPA active... no lags... so there's something wrong on perseus and it's not placebo, as stated by other users.

I hope that Andrei will find soon a solution, because I really like Perseus. Its controls are great, display calibration unbelievable and has everything I need....

But for me reactivity from a powerful quadcore like note 2 is the number one priority...
[Galaxy Note II Original Android Development] iba21:
There aren't some better values.. you have an asv1 so.. you have 750mV for all bulk.. it means you always are in fbb.. my advise is ti have rbb values for the lowrr freqs.. at last with 500mhz.. if you can..

But.. you have an asv1.. so.. you have to increase the builk tension.. it means have more power usage but less leakage drain..

For me.. you could use that setting.. or maybe increase tensions from 750 to 800.. to have some rbb values in lower freqs

P.s. if you decrease the abb values you have less power usage since tension is less, but more leakage drain, it means, more power usage..

So.. my advise is to set at 800mV for all freqs.. it means you'll have less drain in lower freqs.. or use that setting
[Galaxy Note II Original Android Development] frankcilo:
I agree!

You have already achieved significant reductions in voltage, if you get up too much abb risks blocks.

Even playing with the abb I could not get good battery savings.

raising the abb seems that even increases consumption
[Galaxy Note II Original Android Development] iba21:
Depends on what you have.. my chip is a revision 2.. it has 1000mV.. more body bias value doesen't mean more power usage, it depends of chip quality!

a newer revision has more freqs at rbb, so, little leakage current but not so mouch transistor's freq steps

A worst chip has to use the fbb "step".. it permit to have an high number of transistor's freq with less voltage..

But, it increase the current leakage.. it means.. more power usage..

A bad chip needs an fbb step for low freqs too

And sure.. too high GAP from Gate voltage to Bulk voltage increase the body bias effect

And it's not a good thing..
[Galaxy Note II Original Android Development] ROX77:
Have you checked governor and hotplug settings in Neak? Maybe it's only a different setup... With the right Stweaks parameters I have no lags on Perseus.

Hey AndreiLux, first I want to thank you for putting all this time and effort into developing this awesome kernel.

I'm not a complete noob, but I have to admit, I will from now on, consider myself a noob ...when I see you say (I quote): "I don't believe giving the users more choice is a very smart thing to do." in the first post, and then introduce the ABB feature. Is it just me that doesn't understand ABB? Why would anyone want to change these settings, is our smartphone not smart enough to handle these settings itself?
[Galaxy Note II Original Android Development] quijote1:
I suppose that you don't want to hear: "the ones that came with the kernel". But that's what's working for me. I just boost the audio a little and leave the rest alone. But it may be the rom I am using as well.... which I love....or the Apex Launcher.....

AndreiLux,

I just flashed this kernel and so far I am really liking it!

One question, is everything default setup to save battery life vs stock kernel, or do I have to do something? Is this already under voltage? I dont care to OC as the phone is fast enough, just looking to get better battery.

but I want to know how about QI wireless charge, someone post they can chrage by 900ma.

[Galaxy Note II Original Android Development] iba21:
Bad idea..

The things are 2:

1) app is lieing, so, 2A is not the real current

2) you are overcharging the phone charger module.. i means you can demage that chip or directly demage the battery (it could be explode)

Lithium battery speed up his charge by using different charge system

The better way is to send a charge signal witch increase voltage rapid and decrease it drastically.. that phisical effect increase the possibility to absorbs more electrons in anod..

If you use an higher current with a normal signal, it will demage the battery so fast
[Galaxy Note II Original Android Development] cruzargel:
Same problem
[Galaxy Note II Original Android Development] berkos:
for the life of me i can't seem to find why my device was stuck yesterday on 1000mhz, and only two cores. i was on latest omega and latest perseus.reflashed only omegaROM and cpu works normally, is this intended for battery saving when battery under 50% or...,?thx
[Galaxy Note II Original Android Development] SirCanealot:
Why is 2a not the real current? The charger is rated at 2a and it's for a tablet. The normal note charger (which is also rated at 2a but never gives that for me) usually gives me about 1.6a and I usually observe an equivalent increase in charging speed using the playbook charger.

And Mr Genius, what is the recommended limit on charging the Note II battery then? Given that Andrei has already stated there's no harm in charging the battery over 2a and even provided the maths somewhere. And also given that the Note II charger is rated for 2a anyway (even if it never gives it). Thanks :)
[Galaxy Note II Original Android Development] iba21:
Unh right is 2A.. see now.. than.. 2A is the correct value..

Mr Genius.. ok..

Mr Ignorant, Whould you like to charge note2 with other charger.. your phone your problem..

If battery explode and/or if it lose more max cycle.. it's only your fault

Phone has a chip witch controlls the current flow..

Charger has an electronic circuit

Lithium battery isn't ni-cd or ni-mh battery.. so.. all tech has his own preference

Lithium and poly needs a specify type of charge.. if you use the charger of ni-cd or ni-mh you could have bad esperience..

yep, you could use all lithium charger you find in the box.. but.. all electornic has his own logic.. and.. not all the output has the same.. mmmm.. "graph"

All battery has his own charge logic.. so.. the best is to use what you find with the battery, but, if you prefere to use other charger only to decrease time charge, you have to know you could demage your battery faster and faster

Explode.. mmm.. not.. the chip in the phone will cut off the charge connection if voltage raise up of 4.3V.. more than it.. lithium battery explode..

A faster charge can increase his temperature.. it means you'll lose more "capacity" per year..

Etc etc etc

wikipedia is your friend.. try to read and undestand how lithium and poly works.. and how to demage it faster ;)

So, the battery will loose charge over time faster... Yes true.

I have been (rape) charging my battery at 2 amps (as reported by chip) since the first day that option was available, some 3 months ago more or less, every single day.

Still have about the same amount of charge, with great battery life.

The phone is still fine, didn't explode or shutdown the house's circuit breaker, and no animal has been harmed as of today.

And the funniest thing is that replacing the battery with an original Samsung one is about 20€...i think I will be able to afford that... Somehow...

Wait.. you have to know i thinkd battery charger had a 1A of output.. so.. you understand.. if phone has 1A and if you charge with 2..

It's normally if you use another charge with the same output

But.. ypu have to knoe charger has different charge logic.. and.. not all works good..

But.. if a battery costs 20€.. no prob!! ;)
[Galaxy Note II Original Android Development] CekMTL:
:)

Your point is exactly my point... If all this insane battery voodoo ends up in having to buy a new battery in two years instead of three... Well, in my case it takes a lot less time to charge than stock, doesn't heat up (more) when charging, and lasts about the same... So yeah, no problem to spend 20€ every two years on a new battery, if I still have the same phone, of course ;)

Ps: never said I changed charger; am using the same stock white Samsung charger that came with the phone, and in tiny print the output is 2000 mAh or so they claim.
