SpeedMod K5-3:

Very good battery life in mixed usage too.

SpeedMod K5-3 (XWLSD NeatROM Lite v4.3): Battery loss of 1,43% per hour, Wifi: 14,3%, Awake: 12,1%, Screen: 10,0% => loss*(1-screen): 1,29%

It's nearly the same as for best Jeboo kernel on this ROM.

Here are some screenshots:
[Galaxy S II General] It_ler:
Thanks for your help.

Let me think about it.

Maybe I can do one benchmark test on each kernel I flash ... I really don't want to spend too much time with many different benchmark tests.

HiroX 5.3:

I tried it again.

First I flashed the Medium version (for manual UV) - worked fine.

Then I was confident and flashed HiroX Extreme - stuck at Samsung boot logo.

Reflashed Pre-rooted XWLSD with PC Odin > flashed SpeedMod K5-3 as tar with Mobile Odin app > flashed XWLSD NeatROM Lite v4.3 as zip in CWM recovery > and I had my first boot loop on custom boot animation.

Ok, now restoring my last nandroid backup in PhilZ CWM recovery. Hope that I am back to "normal".

> No, still on boot loop.

Re-flashing the ROM > boot loop.

Re-flashig latest PhilZ kernel > re-flashing the ROM again > phone boots again.

Next try to restore my last nandroid backup.

Successfully restored my last nandroid backup, but as it was created with SpeedMod K5-3, it does not have preload partition.

Now some of my mods are gone ... will flash latest PhliZ kernel and then the missing mods.

EDIT:

Now I am back on my "old" system.

Creating a new nandroid backup including preload partition ... with latest PhilZ-touch kernel v4.76 for XWLSD.
[Galaxy S II General] eusousuperior:

[Galaxy S II General] It_ler:
PhilZ-touch v4.76:

After stucking at boot logo, boot looping, flahsing the ROM again, restoring my last nandroid backup, flashing the kernel again, etc. I flashed PhilZ-touch kernel v4.76 on my XWLSD NeatROM Lite v4.3.

It is very stable and smooth on my phone.

Everything works fine.

Moderate battery life in night use.

PhilZ-touch v4.76 (XWLSD NeatROM Lite v4.3): Battery loss of 0,60% per hour, Awake: 1,8%

Maybe it's because of the "turbolent" night I had after flashing HiroX Extreme.

So I might re-do the tests. I really want a stable system now.

EDIT:

In settings wifi advanced, turn wifi off when sleep or set to on when charge, boost battery time.

[Galaxy S II General] Vihru:
good morning.. i have one important question about battery life..

baseline is: i have frozen many apps with titanium backup and turn some apps bootcomplete receiver off with autorun manager pro.

here it is: if i shutdown my phone, change battery and turn phone on.. then set custom ref in BetterBatteryStats.

then i start to sleep and my phone consumption is 0.0h / in 10 hour.. thats good.. is it?

and then.. i using my phone. phone calls.. text messages and whatsapp messages.. if i then put my phone sleep..

then consumption is not 0.0h in 10hour BUT if i reboot that, then that consumption is again very good (0.0.h / 10hour)

so.. i am asking this: is there anyway to get that same situation with some app killer or something that consumption is same

as that when i power on my phone with new battery and consumptino is then very good? im thinking that some apps is taking battery or something.. ?

thanks for helping.

[Galaxy S II General] parag1dubey:
hey lt_ler, will you be testing dorimanx 8.1? Its out now. Please try it... Thank you : :)
[Galaxy S II General] It_ler:
Have a look here to "calibrate" your battery / settle down the battery stats chip in your phone.

That's what I do everytime after flashing a new kernel (and/or ROM). And sometimes I have reliable results on first battery cycle.

If not, I have to re-do the tests.

The more cycles you make on the same firmware (ROM + kernel), the better is the battery level indication.

Caused by the battery stats chip (MAX17042) which is built-in our phones. It has a kind of "auto-calibrating" feature ... needs only some time to auto-adapt to the correct power level of the battery.

So best would be to wait for 4-5 battery cycles and then do the battery tests.

But as I don't want to wait that long time, I try to use the linked method to get the battery stats chip settle down quicker.

Sometimes I verify if the settling down works fine by repeating the battery tests on the same firmware (ROM + kernel) several times.

And most of the time, the results are very similar.

So it seems to work.

Only when recognizing "strange" results, I don't trust them and repeat the battery tests on a second (or third) battery cycle.
[Galaxy S II General] It_ler:
Thanks for the info.

I am sure that I will test latest Dorimanx kernel.

But I can't say when.

I am busy ... company internal training for the next few weeks ... with travel to a foreign country.

So I have to "slow down" my kernel tests a little bit as I don't want an unstable system.

Maybe stock / PhilZ kernel is best for this trip, as it has very good battery life on my phone so far and is very stable.

If I become bored I will continue testing kernels ... will save the recent version on my phone ... just in case ;)

Hey lt ler, what kernel are you testing now? Dorimanx, unfortunately, is no longer in the running for me because of wifi issues. If that gets fixed in the next version, there is a good chance some thing else will be broken.. Unless red tells me that dori has released something stable, i won't go that way. Presently on siyah 6 b4 with many's tweaks applied. Curious about speedmod but hoping recovery gets updated.. Dorimanx seems to have lost his way..

[Galaxy S II General] Dexter_prog:
I managed to get better battery results during idle time by installing another rom (Netrom) and not reinstalling all the apps I had (to see if one was causing the battery drain), but the screen depletes the battery sooo damn fast. Today I woke up and battery had gone to 95% (BBS reported 0.8%/h, which is fine by me), I used the phone for 10 minutes (tapatalk) and it went down to 89%. That means that in one hour of screen usage my battery would drop 36%, which is insane.

I'm on wifi, using Neatrom 4.4 and Siyah 6b5.
[Galaxy S II General] It_ler:
Re: [04 Mar 2013] [KERNEL TESTS] [SAMMY ROMS] Kernel battery tests and benchmark resu

This is in fact a very high battery loss. If you have another battery for your phone, change battery and check again.

Maybe the battery needs to be replaced.

You should also check Many40's signature and have a look at his battery configuration for SiyahKernel on NeatROM.

@ ltler, why do you use LSD despite LS8 having the best battery life?
[Galaxy S II General] mr_zuff:
R: [04 Mar 2013] [KERNEL TESTS] [SAMMY ROMS] Kernel battery tests and benchmark resul

I think mr. It_ler answered to this question some time ago..

Ls8 is still a "beta" fw(leak), just a bit newer than Lsj. LSD is the new official fw with western europe Csc, so it should be newer and stable than Ls8 :)

LSD also has been analyzed and came out that it is to prefer over ls8 for a lot of small fixes: one for all, exynos exploit (even battery lasts a bit less :D )

And if I well remember, he uses sgs2 as second phone and with a light usage, so he can use it to test new roms (based on stock) and kernels to help us to choose! He doesn't need the s2 for the whole day :)

I hope I helped mate :)
[Galaxy S II General] It_ler:
Thanks for answering my question :highfive:

Just a minor addition/correction:

XWLS8 is also an official firmware release (only XXLSJ was an unofficial leak), but there are many (small) changes ... indirectly indicated by the significantly higher change number of XWLSD.

So there must be some "good" changes/fixes/patches/etc.

I like to be on the latest/newest version ... and the difference between XWLS8 and XWLSD seems to be "great" - I regularly follow Tungstwenty's comparisons of the different stock ROM versions.

That's why I keep XWLSD as base ROM, although I had a little bit better battery life on XWLS8.

Don't want to be a troller but my opinion is that you just kept your phone with the screen on, because there is no app in the battery consumtion. I lost 30% keeping my screen on for 4 hours so I could easily have 15 hours of screen on time but that just don't mean anything.

[Galaxy S II General] It_ler:
What works for one user's phone may not work on your phone.

You have to test it yourself on your phone.

Maybe undervolting of -75mV works for some frequencies, but lead to instability for others.

UV is always a compromise between stability and battery saving: The more voltage you try to save the more stability you will lose.

If you want to make it "ideal", you have to find the optimum voltages (lowest values which are still stable) for each frequency on your phone.

As I am too lazy to do this, I keep running on default/stock voltages.

But it's your choice to try something different.

Good luck !
[Galaxy S II General] dkimmortal:
Hi guys! thank you for the input, i love to use this as a guide especially since it seems my phone always gets lower values than those mentioned here (max 3hr screen time with 15+hrs)

I feel like CM does better sleep but it drains more when you use it, while Sammy does a little bit worse during sleep and drains less while you use it. But thats what my phone does i think... but now that Jelly Bean kernel source is out for some time, is that different? will there be a difference between using CM roms or Sammy Roms?
[Galaxy S II General] It_ler:
As I like Sammy (based) ROMs, I don't flash and test custom ROMs (such as CM).

[Galaxy S II General] bobdoblo:
Re: [04 Mar 2013] [KERNEL TESTS] [SAMMY ROMS] Kernel battery tests and benchmark resu

I used to use them and theres always a compromise, always something that don't work properly and bugs.

They are just one long beta test a bit like Dorimanx kernel where even if they made a perfect working version today they will try to add more stuff and break it.

Its a never ending flashing of latest versions and the battery/performance was never any better it was always worse.

Thats why after ages of flashing different CM, AOSP & AOKP ROMs i was very surprised when i went to Sammy based NeatROM and everything just works, is very smooth and has very good battery.

I could give up flashing ROMs right now as everything is great and nothing is broken.

Lots of people seem to agree as there has been a massive shift of people using Stock/Sammy based ROMs, look at the popularity of NeatRom ;)

+1, Exactly.

I already talked this to the developer to get this on 1.8, as you saw, but seems that he is stuck with his own idea : stay locked at 1000 by default then... too bad.

Anyway I didn't finished the day with 1.7 with, because I encountered finally many problems with it : after a nandroid restore and flashing back the kernel : I had some undervolting issues (just put same UV settings as before nandroid restore and device froze, so I tried much less uv values : same problem, tried only to UC GPU to 100Mhz only: freeze !), and some other problems like the scheduler wasn't SIO by default anymore, battery pulling out at 75% and after getting it back on : 45% left, so some strange behavior that I can't explain, so I reverted back to XWLPD cf-root actually.

Anyway bad news, I reserved my Galaxy S3 today and I is locked at my local store for waiting the sim card to finish the subscribe (can takes up to some weeks, I hope not! :D). I sold my S2 to my brother, but I'am still using it until I will get my S3 (he is gentle ;) ).
