[Galaxy S II Android Development] Zytrel:
This is all explained in the OP. V2 also has lower hardcoded internal voltages. With the Configurator you can only adjust arm (cpu).

Also I'd urge not to pay too much intention to this. The amount of battery being saved due to undervolting is minimal. If your device can handle Regular but has troubles with the Extreme versions, just stick to Regular.

Regards,

zytrel.

I think , dysfunction of wifi , for reason undervolt.but undervolt not concern.

I not write english full. Exe cusemy.

Understand? ?
[Galaxy S II Android Development] It_ler:
In light version, there is no undervolting, if you set the voltages in Apolo Configurator to "light" too.

If you still have issue with wifi, your phone/wifi router may have basical issues with the new wifi driver.

And you have to flash a kernel using the "old" wifi driver.

But first you should forget / remove your wifi connection in system Settings > Wifi. And then try to re-connect to your WLAN again.
[Galaxy S II Android Development] pedestre:
Don't know, some people have problem with new wifi drivers. I'm going to update drivers in 4.9, will see if it can solve those issues. Meanwhile you can use 4.6

hello pedestre.. i am using the same rom bitfor v10.. dont have any issues. using latest 4.8v1 ext.. kernel.

the thing that i noticed is deepsleep in not achieved more in your kernel u need to look into this..
[Galaxy S II Android Development] It_ler:
First, I recommend to check in BBS what is preventing the phone from going into deepsleep.

Maybe it's a "bad" app.

My GS2 achives the best deep sleep with "ligh" version of the kernel...

I tried "Regular" for a long time, the phone was fluid and fast, but deep sleep was awfull (almost 1% per hour, with 3g and wi-fi off)...

Now with "Light", deep sleep is back: 7h of "my sleep" 1% of battery :D ... and in Antutu i got the best result ever: 10142 points

My GS2 doesn´t like undervolt while it sleeps :p

Maybe your GS2 is like mine... try Light version and see if "deep sleep" gets better :good:

I think in is tests, It_ler achieved better battery with "Ligh" version then with "Regular"... and like Pedestre says: not always unvervolt means better battery ;)

Normally my phone doesn't heat up either but with charging and navigation on, it does. Have you tried navigation and charging at the same time?
[Galaxy S II Android Development] mad_hat:
Thanks for your insight. To get the better Deep Sleep, I tried the Light version but immediately had problems with the Wi-fi which I never had, so I cannot say if the Light is better than the Regular version.

[Galaxy S II Android Development] Vivek_Neel:

[Galaxy S II Android Development] Addicted2Speed:
I don´t have any problems at all.... all working fine here :)

Currently i'm with 13% battery left, with 3h13mins on screen wich included: 26min of GPS on, 33min of Wi-Fi on (inclued net navigation, facebook, whatsapp, google play udates, anti-virus updates), 29min of 3G/data on (facebook + whatsapp), 35mins of calls... not bad i think :p ...

With regular i could do a little more screen time with the same usage ( + 15 to 20 mins) but as i have already refered, deep sleep was more week...

All this with standard settings in Apolo Configurator, except cpu voltages (i choose regular -50mv).
[Galaxy S II Android Development] kswiss86:
wow thats is impressiv. never can go over 2h Display on. What is the secret for this?

(look at my signature for my Rom/Kernel use)
[Galaxy S II Android Development] Addicted2Speed:
No secret at all ;) ...

You should let the kernel settle down for 2/3 complete battery cycles to achieve maximum battery :good: ...

With light version of kernel i achieve +/- 4h of screen time (3h55 ... 4h10 -> depends on the usage of 3G or Wi-Fi)

With regular version of kernel i achieve +/- 4h30m of screen time (4h15 ... 4h30 -> depends on the usage of 3G or Wi-Fi)

All this with stock settings on Apolo Configurator.

Currently i'm trying another modem (BVLP7, my favourite) because XXMS2 overheated my phone while i was on Wi-Fi (i thought it was the kernel but since i changed modem, no more overheat) ;)

I think this modem is more battery friendly then XXMS2, but i'm going to let it settle for 2/3 days to test it further.

Here is the link for the modem (provided by veyka): http://veyka.co.uk/sgs2/radios/I9100_radio_BVLP7_CWM.zip

Just flash it via CWM recovery and let the modem settle for 2/3 days :good:

For me, it happened the opposite :D ... Battery drains more slower and lasts longer with 3G and Wi-Fi ...

Modem varies on your region, it is also usually the cause of battery drain. Best bet is to find out which modem your stock ROM uses.

[Galaxy S II Android Development] AnubuRe:
Thx for info :good:

However like spacemonkey was having with v4.5 I'm having issues with deep sleep, with v4.6 my phone will hardly go into deep sleep. I 1st noticed this the other day but thought it was due to a newer version on my rom or an app, but phone will still not go into drop sleep with the older version of rom and the suspect app removed, I reverted back to apolo 4.4 and phone sleeps again.

Anyone have any suggestions why this is? Was using extreme v1.

Peace
[Galaxy S II Android Development] pedestre:
Sometimes extreme undervolting produces that effect in some mobiles(especially in low frequencies) . Try V0 and likely deep sleep will go back.

I'm using V2 12 hours today (light use) and 91.6% has been deep sleep.

No problem at all with that
[Galaxy S II Android Development] tghandour:
Zzmoove is working great here without sticking to high frequencies a lot. I am running on 200-1000 MHz and 200 MHz usage is more than 50% . You might try SLP governor as it is a good one indeed biased more towards performance.

It's not important what version I use, it only depends on your device. My mobile is not sensitive to voltages so I can use V2 without any issue, but it doesn't mean anything.Your ideal version can be other and you can have better battery life than me. Only way is testing, starting with regular.

I'm using wanamlite14.6 and extreme v0 kernel.

At first I didn't know to much about this dev or kernel though after reading much I can see how this is a great kernel.

My only confusion is which kernel to use, initailly from feedback here on xda I went str8 ahead with extreme v0, as this I understood is going to give better battery performance etc.. though after reading about 'apolo configurator' and that the phone itself will set optimum voltages etc, then is there a need to change or set anything via the configurator in relation to v0?

The dev states not to change any values on extreme v0 (all extreme versions in general I take it) via the configurator.

Though given the kernel I am using, extreme v0, should I set the voltage options (on tab 2 of the configurator)to be extreme v0, or leave the values as the phone has set? there are options for other kernel versions (v1,2, regular) though I guess they are redundant given I am on v0? or can these other configurations be used with v0 kernel?

In all I went ahead and set/selected v0 as a 'temp option', after 30sec I had a frozen screen and a reboot. I figure I answered my own q above and just to leave it! or did I..

Should I try to improve the speed/response of my phone using the configurator settings for v1,2 or regular, will they work, or do I need to change to that kernel type?

I am after better battery (which I have seen an improvement so far) and most of all performance (I hate delays and lags).

Yes but only if it's a Samsung based rom, as ur using NeatRom it'll be fine. I'm using it on chameleon and works great. If u tried to change the rils on an aosp based rom like aokp or cm it wouldn't work and would break ur baseband and lose imei until u reflash. Always good practice to backup before flashing just in case :)
[Galaxy S II Android Development] Addicted2Speed:
As long as is a JB modem you can use the correct RIL (in my opinion doesn't do much of a difference) ...

Otherwise if it's a ICS or GB modem if you flash the correct RIL you won't get any signal (i tried with BVLP7 and got to restore the original ROM RIL).

BVLP7 modem is making wonders in my network/location, but for other networks/regions other modems could be better (just have to try until you found it , as i did).

Regarding modems for different regions i recommend this thread (closed but with essential information about modems + rils):

[Galaxy S II Android Development] s_m_a_s_h:
Hi, well I went ahead about 1.5hrs ago and ran v0 kernel with every setting in configurator (regular light v1& 2) and benchmarked the tests in antutu.

I then did the same with regular kernel.

I got a few frozen screens/reboots running antutu with certain configurator settings (always happened at 'write speed test'; I can only think that the settings from configurator are incompatible with my phone/ROM. [all tests were done one after another negating change of kernel and the occasional reboot that was needed after frozen screen]

The best settings I found were v0 kernel with stock (phone chosen settings; where I didn't change anything from reboot) result from antutu was 9903, the highest in all tests I did.

I'll try the other kernels later.

If I may ask just one more thing, what's the significance of selecting configurator settings; is it if you're on one apolo kernel you can change to another apolo kernel settings/parameters (via tab 2 voltages) without flashing the specific kernel i.e one kernel acting as another, or is it that it takes the best settings/parameters from one kernel to add to another to make it better i.e. a mixture of both kernels?

Thanks for all the advice.
