actually latest batteries last longer if they not fully discharged. I read somewhere that keeping the battery @50-70% and recharge to 95% is best for battery life. not easy to follow so i just recharge by the end of the day and never leave it charging overnight and keep it away from heat sources.

Regards
[Galaxy S II General] bobdoblo:
I always leave mine plugged in overnight so it is charged hours before I wake, normally plug it in at ~11pm and unplug ~7am and sometimes I just leave it plugged in for hours after that especially if I'm downloading torrents.

No point unplugging it only for the downloads to run my battery right down then having to charge again.

Hasn't done me any harm:)

Jeboo v2.2:

I just flashed Jeboo kernel v2.2 (CWM version) on my XWLSS NeatROM Lite v4.7.

It is very stable and very smooth on my phone.

Everything seems to work fine (wifi, bluetooth, camera, video recording, video player, GPS, custom boot animation, etc.).

First result on AnTuTu: Jeboo v2.2 (XWLSS NeatROM Lite v4.7): 9767
[Galaxy S II General] It_ler:
Jeboo v2.2.:

Bad battery life in night use.

Jeboo v2.2 (XWLSS NeatROM Lite v4.7): Battery loss of 0,75% per hour, Awake: 2,3%

I received a SMS during the night ... maybe this had impact to the battery life. Or the battery stats chip was not settled down correctly.

As it's worse than for other versions of this kernel, I will repeat the battery test.

EDIT:

Added some screenshots:
[Galaxy S II General] It_ler:
Jeboo v2.2:

Moderate battery life in mixed usage.

Jeboo v2.2 (XWLSS NeatROM Lite v4.7): Battery loss of 1,47% per hour, Wifi: 10,1%, Awake: 12,9%, Screen: 10,0% => loss*(1-screen): 1,32%

It's my best result for Jeboo kernel, but compared to PhilZ and Dorimanx kernels, it's worse.

As I said, I will repeat the night-use battery test.

Here are some screenshots:

Hy It_ler. just a question. how do you keep your screen alive for the 2 hours. you touch the screen from time to time or you actually use the phone for reading or something?
[Galaxy S II General] It_ler:
On my first tests, I clicked on the screen, read some emails, news, etc.

As I wanted to have same conditions for all tests/kernels, then I only clicked on the screen from time to time to keep the screen on.

Alternatively I would have to use the same app reading the same things in all tests.

In the last few tests, I was using an app to keep the screen on for 2 hours.

When I "really" use my phone, my battery life is worse than in the battery tests, but the results would be hardly comparable.

So that is the price I have to pay for getting comparable results without reading the same things ever and ever again.
[Galaxy S II General] It_ler:
Re-test Jeboo v2.2:

Better battery life on second run in night use.

Jeboo v2.2 (XWLSS NeatROM Lite v4.7): Battery loss of 0,63% per hour, Awake: 2,0%

Still not the best battery life but it's Ok now.

First post updated.

Here are some screenshots:
[Galaxy S II General] bobdoblo:
Thats still bad isn't it!

Quite surprising actually as i thought Jeboo was stock with extra governors & schedulers?

What are the default governor & scheduler settings It_ler, if they are different from stock and you get a spare cycle (not likely i know) it would be interesting to see if it makes a difference having it on pegasusq & cfq?

Nice job as usual mate:thumbup::)

★NeatROM★ Mods ********************* Battery Guide
[Galaxy S II General] It_ler:
Oh ... I saw your post too late.

Already flashed a new kernel.

But AFAIK, Jeboo is based on latest JB kernel sources. That is not the same as XWLSS.

Maybe the latest sources from Samsung are from XWLSD ... but I don't know.
[Galaxy S II General] It_ler:
Dorimanx v8.16:

I just flashed Dorimanx kernel v8.16 on my XWLSS NeatROM Lite v4.7.

It is stable and smooth on my phone.

Subjectively, touchscreen is not as responsive as on stock/PhilZ and Jeboo kernels.

Nearly everything works fine (wifi, bluetooth, GPS, Camera, video recording, Gallery, custom boot animation, etc.), but stock video player still does not work when started directly (only via Gallery).

I applied the "video player fix" > Notes 2 video player which works fine, but no live thumbnails for me. Most thumbnails are black, only some show a static (first) picture.

First result on AnTuTu: Dorimanx v8.16 (XWLSS NeatROM Lite v4.7): 9254

Now preparing for battery tests.
[Galaxy S II General] bobdoblo:
Video player still not working! :rolleyes:

Is RAM still missing and stuttering music on screen off still a problem too It_ler? :cool:

★NeatROM★ Mods ********************* Battery Guide
[Galaxy S II General] It_ler:
No stuttering while playing music when screen off so far.

RAM seems to be Ok ... at least I didn't get an out-of-memory or low-memory message (although it's about 41 MB less than on stock/PhilZ kernel):
[Galaxy S II General] mathmachado:
One question [MENTION=4229457]It_ler[/MENTION], do you have fast dormancy enabled on your tests?

By the way I've flashed neatrom 4.7. First look it feels more battery friendly then LSN, but I still dont manage to get good results. I've managed to prevent unwanted wakelocks, but 3g and phone signal still gives me at least 1, 7% per hour over night with philZ (whatsapp on, facebook and other apps greenified)

I guess that since I'm from Brazil, I'll have to wait for a more battery friendly firmware or modem :(
[Galaxy S II General] It_ler:
Tested with FD enabled and had massive sec-ril wakelock.

Then tested with FD disabled, had nearly no sec-ril wakelock and better battery life.

So since I'm on JB ROMs, I have FD disabled.
[Galaxy S II General] It_ler:
Dorimanx v8.16:

Moderate battery life in night use.

Dorimanx v8.16 (XWLSS NeatROM Lite v4.7): Battery loss of 0,63% per hour, Awake: 1,9%

It's Ok, but significantly worse than for v8.14 on XWLSN.

Maybe the better smoothness of this kernel (v8.16 is way smoother than v8.14) lead to a little bit worse battery life?!

Let me check its battery life in mixed usage before judging ... making the decision, if I repeat the battery tests or not.
[Galaxy S II General] It_ler:
Dorimanx v8.16:

Good battery life in mixed usage.

Dorimanx v8.16 (XWLSS NeatROM Lite v4.7): Battery loss of 1,34% per hour, Wifi: 10,3%, Awake: 12,0%, Screen: 10,2% => loss*(1-screen): 1,20%

It's nearly the same as for stock/PhilZ kernel, but a little bit worse than for v8.14 on XWLSN.

I think that v8.16 is much smoother than v8.14 but needs a little bit more battery power ... and this kernel seems to be better for a more "heavy" usage IMO.

For my "light" usage, it is not the best option ...

Here are some screenshots:
[Galaxy S II General] kadivarz:
bro did u change any settings inside?? cpu speed or profiles schedules gov..

any thing ??

i read that the new in this one is the zzmove gov tried that ??
[Galaxy S II General] -iNCEPTiON-:
Just tested v5.03.0 :) its awesome :)
[Galaxy S II General] It_ler:
No, I tested on completely default settings.

If you tweak the kernel manually to your phone/needs then it will surely have better battery life.

I just want to have reproducable and comparable results ... so I try to avoid any (manual) changes.
[Galaxy S II General] Emre9110:
I think u must re-test dorimanx kernel after Philiz :) Night use is not good and it affect mixed too
[Galaxy S II General] It_ler:
No, you are wrong.

I may re-test Dorimanx v8.16, but maybe there will be a new version of this kernel soon.

Then I will first test the latest available kernel version.

First I want to check my system's "stablility" with stock/PhilZ kernel.

Maybe there was something changed which has influence to the battery life.

When I am sure that my system is still "stable", I will continue with testing other kernels, such as latest Dorimanx kernel ;)
[Galaxy S II General] It_ler:
PhilZ v5.03.0:

I flashed PhilZ-touch kernel v5.03.0 on my XWLSS NeatROM Lite v4.7.

It is very stable and very smooth on my phone.

Everything works fine so far (wifi, bluetooth, GPS, camera, video recording, Gallery, live thumbnail in video player, custom boot animantion, etc.).

First result on AnTuTu is already added to the first post.

Here are its battery results on first run in night use.

PhilZ v5.03.0 (XWLSS NeatROM Lite v4.7): Battery loss of 0,56% per hour, Awake: 1,6%

It's a little bit worse than for the previous kernel version on this ROM.

So I will have to check the battery stats in detail and repeat the tests ... maybe it's just a normal "noise".

I just want to be sure that it is no permanent "drift".

EDIT:

Added some screenshots:
[Galaxy S II General] bobdoblo:
Can't see your antutu score mate?

I just tested and got my highest ever 10380

★NeatROM★ Mods ********************* Battery Guide
[Galaxy S II General] It_ler:
Upps ... thought I've already added it yesterday.

Here it is: PhilZ v5.03.0 (XWLSS NeatROM Lite v4.7): 8909

But it was directly after flashing the kernel, so I expect a more reliable and higher result on next run.

Should be nearly the same as for previous kernel version ... as it is still "stock".

My subjective smoothness is very good ... regardless of the benchmark result.
[Galaxy S II General] It_ler:
PhilZ v5.03.0:

Very good > excellent battery life in mixed usage.

PhilZ v5.03.0 (XWLSS NeatROM Lite v4.7): Battery loss of 1,25% per hour, Wifi: 10,1%, Awake: 11,5%, Screen: 10,0% => loss*(1-screen): 1,13%

It's slightly better than for previous kernel version.

So my system seems to be "stable".

I will check it on a few battery cycles before continuing with further kernel tests.

Here are some screenshots:
[Galaxy S II General] It_ler:
Second run on AnTuTu: PhilZ v5.03.0 (XWLSS NeatROM Lite v4.7): 9857

Hi mate, sorry but I couldn't answer earlier.

I'm not familiar too much with this kernel coz I don't use CM based roms. However AFAIK it's a "Siyah" kernel modified by mcm118 and adapted by rush85 to work on newest CM based roms. More details you can find in this post taken from the kernel's thread:

[Galaxy S II General] ciprigeorgiu:
Hey It_ler...you have lots of experience with rom and kernel flashing. Do you think that there is a problem if I flash LSS kernel (Philz 4.03) over LSN rom (NeatRom 4.6.1)? I flashed it, it works but I was wondering about battery life.
[Galaxy S II General] bobdoblo:
Well i don't notice any difference:thumbup::)

Same with modems, some say they need to settle but imo its rubbish.

I get the same signal strength and data speed in the first 5 minutes as i do 5 weeks later!

★NeatROM★ Mods ********************* Battery Guide
[Galaxy S II General] Many40:
IMO there will be no difference in battery life between LSS and LSN philz kernels used on LSN rom because there are no significant changes in kernels' sources.

Need just one retest on stock/PhilZ kernel, as I received some updates (hangouts, etc.) and want to have same battery life.

Hi, for the Rom you have installed the best kernel is Philz-cwm6-xxlsn-oxx4.93.6-signed. I use the same and perfect.
[Galaxy S II General] It_ler:

Dorimanx v8.20:

I just flashed Dorimanx kernel v8.20 (still the latest version of this kernel ... AFAIK) on my XWLSS NeatROM Lite v4.7.

Nearly everything works fine (wifi, bluetooth, custom boot animation, GPS, camera, video recording, Gallery, etc.). Only live thumbnails in video player are still black for me.

And many, many more settings in STweaks app.

(But it was directly after flashing. Will update this result after battery tests.)

But wifi was turned on all the time. Better Wifi On/Off app was disabled ... strange.

Will repeat the over-night test with Better Wifi On/Off enabled again.

But although wifi was on all the time, v8.20 has slightly better battery life than v8.16.

So let's wait for its battery life in mixed usage.

EDIT:

Although the night use was "affected" by wifi on all the time and at the end of the mixed usage test I saw that GPS toggle was on too.

Unfortunately, even on light version I get SODs with any other UV profile (tried all available, such as Regular).

You don't need to wait for my tests.

As I am very happy ATM with Apolo v4.6 light, I will spend some days on this kernel and continue my kernel test probably next week.

Maybe with latest Dorimanx ... but I am not sure.

So it may take some time till I will test this kernel.

Flash it, test it, and report back your experiences :good:

[Galaxy S II General] bobdoblo:
In my opinion I don't see the point in testing Dorimanx kernels yet.

It is an unfinished project, still things not working and there will be another version every day or two.

When he releases a stable version with everything working and Dorimanx himself is happy with it then it would be worth testing.

Thats if anyone is still using the S2 by then:rolleyes:
