Cześć,

I don't know what is the best, but I know what I'm using currently :)

It's Neatrom Lite 4.4/XXMS1 ("squeezed" to Super Lite) + Siyah 6 beta 4 + my tweaks.

With light usage on stock battery (some phone calls + 3G data on stock browser and Tapatalk ap) it gives me up to 2 days on battery / 6 hours of "screen on" time.

It's newest but I prefer beta 4 (eq. beta 5 has limited number of frequency steps)

Back but not with a lot of information. I installed some user apps (WhatsApp, Gemini, Greenify, Gsam, Nova Launcher) and also installed the JB Reloaded theme. Still on Siyah kernal but now with Many40's tweaks applied. Within the first 10 minutes, my phone froze nothing worked except holding the power button which resulted in an automatic reboot. After that I could use the phone normally for like half a day with 1h30m screen time, battery was at a 45% level when it decided to freeze again! Strangely, this time after rebooting my battery suddenly shows 20% :confused:.

Is the reason of freezing maybe because the tweaks are aggressive for my phone? How can the battery percentage jump be explained? Unfortunately no dumpfiles or screenshots since every stat has been resetted with the reboot :(

EDIT: Lol suddenly it jumped up to 21%, but now back to 20% again. You can see the battery usage of -1% in Gsam app.

EDIT2: Aaaand jumped to 21% again lol. Trying to reboot now.
[Galaxy S II General] red.hat:
The tweaks might be to aggressive for your device. Remember each phone is different and as such they respond differently. Try change the CPU UV value to -75 for all steps.
[Galaxy S II General] Many40:
I'm sad that you are not able to achieve as good battery life as you wished (you tried many options already). Maybe your hardware is different or battery aged already. It would be great if it was possible that you check your phone's battery life on other battery (to have comparison).

Concerning your freezes - it's most likely too aggressive CPU UV that your phone can't stand.

Just manually increase voltages a little in Stweaks. If doesn't help (but it should) try also the same with GPU voltages.

Good luck
[Galaxy S II General] dwie:
Everyone thanks for your help these last few days. It seems the last step for me is to try it with a completely new battery. If by any chance it turns out to be the battery's fault then I will let you all know =p.

And do you guys mean that I need to change CPU undervolting from "No undervolting => -75" in the first tab? Or should I change the settings in the in the second tab? If so, in which direction/how? To be honest I have like zero idea what these tweaks exactly do, I just trusted Many40 blindly :D.

Anyone else got an explanation for my battery percentage jump? It can also be seen in the graph of my screenshot...

Most likely you need to reset fuel gauge chip in STweaks.

You can apply dark theme for gSam and check per app analysis of your battery drain. Everything is a Google search away, BTW

Wakelocks issues

I posted some time ago about issues with two wakelocks; audioout2 and gtalk_async_conn. I'm

not sure about solving any

of those completely

but at least audioout2 is not even appearing anymore

on BBS log. I was first using NeatRom 4.3 with Siyah b5 using Many40 tweaks (once more thank you for such useful stuff) but these two wakelocks drainned two much battery.

I tried to find wich app was it, but I couldnt do anything, as they didnt have anything to do with gtalk, which seemed the most logical. Becoming more tired about this I used Hawker's NukeRom and installed NeatRom 4.4 Philz kernel and Many's zips for it, but both wakelocks were still there after some time. It was also interesting that gtalk_async only appeared using data, not wifi. After quite a lot time googling and trying to find something, freezing stuff, I read some comments about audioout2 being related to Viber.

The solution; probably some time ago I uninstalled Viber without deleting data, or made something wrong dont know how, so I installed Viber again, checked use defaults sound, unchecked all the other stuff, went app manager, delete data and finally uninstalled it.

Surprisingly audioout2 its not there anymore!

gtalk_async wakelock is still appearing but less times. I hope this can help somebody.

Questions now: Does Greenify app really help saving battery?Any ideas on gtalk_async?

When battery goes down I'll post a dump file and see if anybody can help me.

Thank you!
[Galaxy S II General] dwie:
Did you even read your own post after posting it? In the future, please upload your dumpfile as an attachment to your post.

Back to your story though, you lose 10% an hour when you "use" it? That means you would have 10 hours of use within a battery cycle? That doesn't sound too bad for me...
[Galaxy S II General] Name.:
Sorry man was in a rush at the time, next time it'll be in attachment.

Yeah, well I usually get 17 hours in with 4 hours screen time, this isn't Bad, but people who use this config get 5/6 hours screen and more then double my idle and screen together.
[Galaxy S II General] electricsheepdreamer:
Try to uninstall Viber and see how it goes.

AudioOut2 wakelock can appear when rebooting while on silent/vibration. Enable sound before rebooting.

Odp: NeatRom + Siyah Kernal. Optimization for Better Battery

Guys need your help. I am fighting with wakelocks and need your help cause I am afraid I do not get it. Below are my screenshots from BBS.

I see a lot of kernel wakelocks and partial wakelocks. However how do I know if they appear when the screen is on or off?

Could anyone please help me to understand how BBS measures that?

Could you tell me if my stats look good or bad? I am trying to get rid of as many wakelocks as I can, however cannot find the good way of correlating BBS data (wakelocks) with apps/processes.

I have Connectivity Service wakelock on the second position of the highest battery eaters. However I have mobile data off completely and 3 bars of signal most of the time. So I do not have problem with signal, but what I have read is that Connectivity Service may be related to bad/problem with signal...

Any help would be highly appreciated.

You can find them in the second or third post of this thread. There are links to different settings (NeatRom + Siyah 6 beta 4, NeatRom + Siyah 6 beta 5 etc.). As far as I know Many40 prefers beta 4 cause it has more CPU steps, which allows better CPU scaling.

[Galaxy S II General] Many40:
1. Post no. 6

2. Because beta 4 has 16 available frequency steps while beta 5 only 6. For some (including me) it gives a little better battery life. It however has a few bugs like stock video player FC, bootloop issue, not saved governor/I/O scheduler after reboot (with existing solutions/workarounds in parallel which can be used to overcome the bugs).

You have to decide which fits better to your needs.

I'm quite interested in why more people use siyah 6.0b4 instead of philz kernel. *(i use siyah too)*

but didn't many40 demonstrate that philz provided more battery? what are the pros of siyah/ cons of philz?
[Galaxy S II General] :
And why do you use Siyah ?

Sent from my S2
[Galaxy S II General] Name.:
Exactly, thats why I'm contemplating whether to go on PhilZ. Cos if I go on PhilZ will there be any major cons? So far the pros are stock video player + better battery.
[Galaxy S II General] :
This kernel thing is getting quite stupid by now. Every kernel has his own thread, where people are posting their observations of using them. You'll have to read them a bit. And still the best way to know is by trying them yourself. What's good for someone, won't necessarily be good for you.

Philz kernel is stock, like Samsung intended it to be. With Siyah or other custom kernels you can tweak the system to your liking.

Sent from my S2
[Galaxy S II General] Many40:
No I didn't. So far Siyah6 beta 4 gave me best battery life. However Philz is very stable and can give also very good battery results so I would recommend it to all s2 users who don't want to bother with kernel tweaking but just want to have properly working phone.

I of course stay on Siyah (even if temporarily switched to latest jeboo to see how it is on other kernels).

[Galaxy S II General] sayatsugu:
Hi Many40,

I have used your PhilZ settings previously on NeatROM 4.4 but I went to test out AOSP (SlimROM in this case) for fun.

Taking into consideration that PhilZ is very close to stock and similarities between governor and I/O, would it be possible to apply them to CM kernels in general ?

Possibly besides the VM and Legacy Hotplug tweaks which is done via init.d script, I believe the other settings could be set via something like SetCPU for example.

If in any case the VM and Legacy Hotplug can be implemented via say... Script Manager or something, in your opinion would it worth a try ?

As I have experienced really good battery life with your scripts, I would want to try it out on CM if possible.

Your advice would be very much appreciated.

Thank you.

Running NeatRom 4.4 and wanted to try different kernels, so most of the time I spent on siyah and it was great, a little on new Dorimanx and it's OK too. But with both of them I have the same problem, if I set CPU governor to be anything else but "ondemand" after reboot I can not use my exSD. Right now back to Philz, but I'd like to know if there is a solution for my problem?

When you flash different kernels you should use a kernel cleaning script first, you may have left overs from your previous kernel causing your sd card mounting problems, after you flash your new kernel you may need to fix permissions in recovery

Thanks to an input from the bbs thread, you can now greenify maps without any problems. Here is what you have to do. This keeps maps hibernated while your phone is asleep and saves battery.

It means that your rom/kernel/apps drain relatively less battery than screen :)

I had even more than 64%.

However I saw from your screenshoths that:

- most likely you used autosyncing

- bluetooth was ON

- you experienced some wakelocks while screen was OFF

- you experienced bad mobile network coverage (a lot of time with poor signal)

So, don't expect great results in this case.

BTW did you implement my rom's tweaks?, I think that only a few of them.
