I'm running CM10 with this configuration, except max cpu freq is 700mhz - yep, enough for normal work. I'm overclocking it when playing videos using SW decoder/playing 3d games. I can get about 2 days with normal usage and wifi all the time except nights. Also I have great results with LPX modem.

[Galaxy S II General] kahar91:
Try running your phone for 24 hours and see if you get 7 hours screen time, because you won't! Max 3-4 hours, even with your settings. Don't mean to troll.
[Galaxy S II General] rakeshishere:
This is 1st cycle after changing the settings based on this thread. I'll surely monitor and keep you updated.
[Galaxy S II General] Psyloid:
Works good on my phone. Def more juice now :)
[Galaxy S II General] alexandru.j91:
i really dont get it.. everywone that i see on this forum gets 5-6 h of on screen time..last night i installed the modem that you have..i made the same settings in extweaks and my batt is like this :

i REALLY DON'T GET IT.. I have low screen on time ..and still my batery is killing me..

i have siyah kernel installed 4.1.4+
[Galaxy S II General] CamoGeko:
You should try cyanogenmod 9 + siyah + magicconfig.

I'm almost positive that you'll be getting over 5 hours screen on time.

Sent from my HTC One X
[Galaxy S II General] alexandru.j91:
i will try ..should i change the modem? or this one is good?
[Galaxy S II General] CamoGeko:
There is no "one" modem that is best for everyone.

You should check out the sticky modem thread to see some feedback about modems and read the guide.

That should help you out.
[Galaxy S II General] gb.yolo:
It depends on lots of factors. My modem may work well for me, but not for you, so you have to find the perfect one for your phone. Then the ROM, and so on :)

Can you post your configuration? I'll try to help you :)
[Galaxy S II General] alexandru.j91:
well now i run cyanogen 9.1 with siyah kernel 4.1.4+ i have installed xxkh3 modem and i use extweaks settings from this post

i live in romania and here there is no fast dormancy on orange network
[Galaxy S II General] yokuyuki:
You're still doing better than mine. Am I just using my phone a lot more than others?
[Galaxy S II General] alexandru.j91:
Yeah but in my screen shots you can see that i only had the scrren on for 41m but usualy after 4h of usage i have 40%battery..and i use agresive settings in extweaks ..

This is very strange ..now i have installed cm9.1 and siyah kernel with agresive settings to se how it manages..and in 2h with 21 m screen usage i have 82%bat.. damn
[Galaxy S II General] TheQuarterMile:
Do you get constant full network in ur area?

If the network quality is not consistent then it can mess up ur battery!
[Galaxy S II General] yokuyuki:
What change did you make? I'm down to 24% now after 2h of screen usage.
[Galaxy S II General] alexandru.j91:
I have 1% batery now i played and listened to music in the same time i managed to make my friend play with my phone to see how much it lasts and here are the samples
[Galaxy S II General] dannykul:
Based on your screenshots your reception is not very stable and most of the time shows Medium to Low level, this can cause a lot of battery drain as the modem tries find a better cell with better reception and uses higher TX power to compensate for low reception, this causes a lot of Wakelocks and drains the battery.
[Galaxy S II General] alexandru.j91:
so.. I really can't do anything?
[Galaxy S II General] yokuyuki:
Using wifi will help.
[Galaxy S II General] gb.yolo:
Try new modems. Search the one for your network operator, and after 2 or 3 days on it judge it and if you can see differences in battery drain well, that's your modem.

I suggest you try 2/3 different modems before you can say "This modem is ok", and when trying each one write down your battery statistics and the signal quality :)

Finally, compare your results and find the best!
[Galaxy S II General] Mittaa:
My wife just got a brand new SGS2, and it is totally stock except she removed most widgets, but Facebook, Mail, Weather etc. sync enabled.

Went to bed with 70% battery. Woke up 7 hours after and battery was ... 70%. Totally deep sleep in 7 hours (no wake up) ... wow :eek:

My SGS2 is 1½ year old and I have been fully re-charged maybe 500 times and a lot of in between charging while driving. I lost 5% during same 7 hours.

I know that batteries tend to stay good for a long time, but still wondering about how all my re-charging cycles have influenced on its present capacity?

I have now ordered a new original battery ... I simply need to know :victory:

BTW @gb.yolo how old is your battery?
[Galaxy S II General] gb.yolo:
It's 9 months :)
[Galaxy S II General] Mittaa:
Good ... I will return with my verdict when my new battery have been running through initial charging cycles.
[Galaxy S II General] okmijnlp:
Make sure you're only using 2g when you're not using a data connection (mobile data settings, only use 2g). This will save battery and increase your signal immensely.
[Galaxy S II General] stanley08:
VeRY TRUE! I use 2G only except i want to download.

------------------------------------------------------------------------------

Anyways, I'm on Wanamlite 12.5 LPX with i think LQ6 modem or so..

My current battery stats are the attached pic below and i'm currently around 3hrs onscreen time. which i'm very sure will go well over 3hrs 30mins in the end. (But mind you, i got sync on, with 2 Email addresses, yahoo and gmail, facebook, twitter, instagram, facebook messenger, whatsapp and even the New Google Now from JB. All running on my phone)

Anyways, i will test these extweaks settings after i'm done with this my current test and let you know whats up. :good:
[Galaxy S II General] Adam Hui:

[Galaxy S II General] waqax:
can anyone tell me how to use this tweak? I mean where to apply/alter these settings?

I'm using SensatioN 4 and Siyah 4.1.5
[Galaxy S II General] sefira:
Install extweaks from play store to find the settings.
[Galaxy S II General] beetlish:
Thanks!

I get easily 2 days with these uv settings using NeatRom. Though I use pegasusq/sio and BLN on.
[Galaxy S II General] gb.yolo:
There are plenty of factors affecting how does your phone react to those settings. Apps which need high gpu work (SODS caused by too low frequency steps or their voltage) is the first example coming into my mind, but also background processes scaling CPU to higher frequencies, the ROM itself, etc...

That's good :)
[Galaxy S II General] Psyloid:
I have cm9 + tweaks, and i get 4 hrs and some screen time which is the best i ever had with this phone.
[Galaxy S II General] beetlish:
Sorry, I forgot to mention I also have the 2 Ah battery. :P
[Galaxy S II General] Sikac101:
I just came across these tweaks. I'll give a try and see! Thanks.
[Galaxy S II General] Mittaa:
A new battery gave me about 10-15% more power. Screen time went from average 3½ to nearly 4 hours on a normal day.

So its not a revolution, but can explain why I feel that battery was lasting longer back in old days where using GB :o
[Galaxy S II General] fgenari:
Hey gb.yolo, this config are stable on news siyah kernels? I'm on 4.1.4 + root box.....anybody test on news kernels? Anybody on rootbox?

Tks for all!!
[Galaxy S II General] gb.yolo:
I have Siyah 4.1.5 and cm10 as ROM and everything is fine :)

If you have some doubts about using these settings, try with less aggressive values first. If you can't see improvements in battery life without lags or lack of smoothness, use more aggressive ones. When you understand something is wrong with your phone (frequent lags, sods, freezes), then it's time to go back to the previous settings :)

Hope it helps :)

EDIT: when I say "without lags or lack of smoothness" I'm not talking about games, but everyday usage.

With extweaks plus you can switch among three different profiles so that when you want to play games such as Asphalt, GTA and so on you can apply settings for getting the best performance while gaming :)
[Galaxy S II General] theflyer1972:
wow GREATgreat I tried the settings of the first page the battery lasts me much more

THANKS
[Galaxy S II General] Henry_dee:
I'm testing it in rootbox 2.6 with siyah 4.1.5 like about 2 hours... i know that isn't much, but until now, i get no freezes(even with chrome).

About the battery life, is pretty much good, i was using chrome, xda, whatsapp, etc with data turn on, and 1 hour later, i had 20% less.

Keep in mind that is the first time i'm using rootbox, so is the first cycle of charge. I'll keep trying and then post the results .

[Galaxy S II General] angelusnovus:
this works great, ty!
[Galaxy S II General] gb.yolo:
Your issue is gpu related. Try to change GPU thresholds (only UP thresholds, not down) and use lower values.

If you post screenshots about your battery life (settings->battery) I can help you find what's killing your battery.

Also, install BetterBatteryStats (xda version, which is free), and after a complete cycle of discharging, post screenshots. It seems like that in your case the battery drain it's not cpu/gpu related (and so it can be solved with my settings).
[Galaxy S II General] mubeenshahid:
Same here .never got more than 2 hours 30minz of screenon
[Galaxy S II General] hassaan123:
just applied these on RR and siyah :) I hope the results would be good. THanx alot !
[Galaxy S II General] clifffhanger:
It all depends on the usage; browsing, texting, a couple of calls could probably give you 5 hours+ but gaming and using hardcore apps, say goodbye to long hours of display. Still these configs specially what geko95gek started gives you a huge difference on battery life and performance compared to stock kernel settings. - in the end it's not the settings but how you use your phone :D:D:good:
[Galaxy S II General] mubeenshahid:
My usage is browsing , xda ,tapatalk,temple run and music listening
[Galaxy S II General] vpraveenis:
Oops.. Wrong thread. Delete
[Galaxy S II General] clifffhanger:
Music doesn't demand screen on so consumption won't add to your screen on time. Temple run on the other hand might be addictive and if you can notice, 1 run could drain 1 - 2 percent of your battery. compared to browsing, tapatalk etc.

Might as well try using your phone for 1 cycle just with light usage and compare it to another cycle with moderate or heavy usage. :good:
[Galaxy S II General] illuminato 67:
Hello gb.yolo, nice to meet you. I think these settings ExTweaks are very very interesting.

I also use Siyah 4.1.5 and CM10.

A single comment. With the recommended values ​​for the GPU (step and voltage) my S2 freezes all the time.

This may depend on my smartphone, surely, whereas S2 are not all the same.

But do not think that these settings are a little too extreme?

Thanks if you want to answer.
[Galaxy S II General] superleeds27:
Right. CM10 and Siyah 4.1.5 Does nothing for me. CM10 is the likely issue here.

Im going to try these settings on Siyah, using Chamelon ROM i think.
[Galaxy S II General] gb.yolo:
Well, I do think they're not very aggressive. For example, with firmwares such as XWLPU, CPU and GPU UV can go up to -100mV and yes, now they're aggressive, very aggressive.

I made this thread to inform people around that 7 hours of screen usage is not just a myth.

However, with everyday usage, I think that you cannot go beyond the 6hr threshold, simply because even if in deep sleep your battery discharges: let's say that in a 18 hrs usage 10%-12% of your battery is spent on deep sleep, and another 10%-12% on awake state. Sum up and you get 20-24% of battery completely lost if you're trying to get the maximum from your battery.

Take a look at my screenshots: 11 hours of battery life, of which 7 where spent on 'screen on' state: this is an extreme test. With an usage of 16 hours, I may have reached 5 hours, or 5 and a half with wifi instead of mobile data.
[Galaxy S II General] sidrocks89:
UV to -100mA..still running smooth. On RR 2.6.1.
[Galaxy S II General] droidstarxx:
Omg. I this is so true. With xwlpu rom i can uv up to -75 just tried it. Still smooth :) idk if the uv is working. Loljk haha :) thanks imma try -100 later.

Is cm9/aokp better for battery life or the samsung based roms?
[Galaxy S II General] droidstarxx:
Depends on how you use it. :) some say aokp. Some say samsung based. For me samsung based. Try. :)
[Galaxy S II General] gb.yolo:
As droidstarxx told you, it depends on how you use it. He said samsung based, and I agree with him, but aokp based roms still can give you a good battery life experience :)

The culprit for my bad battery life is fast dormancy. Enabled fd = 3hrs scrn time + hsdpa always on.

how to go beck to default by CWM? short instruction needed.
[Galaxy S II General] gb.yolo:
If you want to reset your extweaks profiles, and so revert to DEFAULT settings (NOTE: you won't return to your previous settings, you will completely reset them):

Reboot to recovery

Reset extweaks profiles

Reboot

And you're done :)

[Galaxy S II General] Henry_dee:
Well, i've been testing this config for a week and my results was poors. When i was on miui or another ics rom and siyah 3.5.2, the battery life of my phone reachead 5 ours of screen use. Now with Root Box 2.6 - 2.7 JB and siyah 4.1.5, with this configs the battery life reaches just 3 and a half hours with screen use. The only advantage is that i have no partial and kernel wakelocks anymore.

Before i forget, while i was using the phone, usually was on chrome (with so much fc's), xda, mobo player, youtube, twitter, xbox and halo waypoint apps, flipboard, and many games (granny smith, dead trigger, spirit, etc - 2 or 3 games per charge cycle).

Now, i'm gonna try this with official AOKP (pure AOKP) and siyah 4.1.5 and later will post my results again.
[Galaxy S II General] redrumsilence:

I was few days on those setting on Thunder bolt JB room. and I got max up to 3h on screen charging every day. not good for me cos room Is not smooth anymore. I am changing to previous but I will try this on different room later.
[Galaxy S II General] gb.yolo:
Sadly on JB roms you can't achieve results better than ICS roms. We have to wait 'till samsung releases JB code for our S2 and developers for building newer (and more powerful of course) custom roms; then we can judge JB.

Try my settings on ICS and tell me your feedback, if you want to try :)

P.S: Don't feel sad if you reach a maximum of 3hr on screen. That's common among JB users :)

[Galaxy S II General] CounterC:
It's true...

Hi guys,

I tested the above configuration for some weeks now: Modem: XXLPX Phone: XWLPF and ExTweaks profile.

The best thing in this config is that when u are not using you're phone, it is barely consuming battery (like it should be). Maybe 1% per few hours.

I get through the day with 15-20% of battery and mild usage (mail checking, some calls, some sms, some series with mxplayer,...). During the night it consumes only 1% per 8 hours, sometimes even 0% (flight mode, alarm on)!!!

Instead of charging your phone once a day u only have to charge it 2-3 times a week!

My average screen time with normal use is 4 1/2 to 5 hours.

I recommend this config for everyone owning a SGS2. It's the best I know so far when it comes to battery/performance.

The ExTweaks settings work flawlessly and help to save even more battery!

For me 3 things are important: Battery life, MHL support and Jkay support.

This configuration has it all !!!

good luck :good:
