lt_ler, could i ask to introduce this test: https://play.google.com/store/apps/details?id=com.rightware.tdmm2v10jnifree&hl=ro

From my testing i came to the conclusion that some custom kernels has low gpu score even if if its overclocked.

This test( made by 3dmark creators) is quite good, and based only on it i could tell if an kernel is good or not( at gpu power).

Its better then nenamark2.
[Galaxy S II General] It_ler:
Thanks for the suggestion.

But I really don't want to add more benchmark tests/tools.

For me, battery life and real life experinece of smothness is more important than numbers of a benchmark tool.

I am already thinking about skipping all benchmark tests and only doing the battery tests for furture kernel and stock ROM tests.

[Galaxy S II General] jackbauer2411:
How do you achieve a night use like that? I have lost 2% in 4 hours of sleep... Here are my battery stats, maybe you can tell me what I can improve?

I'm on NeatRom 4.2 Lite, using stock Philz Kernel (b22), Aroma Mods and I have frozen a lot of useless apps... WhatsApp and Gmail Sync is active, Wifi on all the time..

Your night use is already really good. You had Wifi on all the time. I hadn't. But your main Wakelock is tweetcaster. I personally don't use it but maybe it can be configured a little more. Again there isn't anything else you can do. :thumbup:

And you can try to disable wifi, just to check, if it leads to better battery life for you.

Good luck !

First revelant test overnight IDLE deep sleep only : lost 4%, much worse than with full Gmail app realtime sync. I will wait for now my day mixed usage but it's already worse than with Gmail app synced aswell... :eek:

I will wait tonight and maybe revert back to it.
[Galaxy S II General] It_ler:
Change no. 2:

I compared my current XWLPD system in battery tests with auto brightness disabled (fix on lowest display brightness) and enabled.

No difference in night use (as display was off all the time), and in mixed usage (about 2 hours screen on in about 20 hours test => about 10% screen on), I recognized a difference of about 19 hours (for 100% stock battery) => about 26% less battery life for auto brightness enabled.

How ... that is a significant difference IMO !
[Galaxy S II General] 00raq00:
How did you calculate it? You said that "about % less", so do you calculate like this?:

%Result=(%disabled-%enabled)*100/%disabled

%disabled means % battery after test with disabled function

%enabled means % battery after test with enabled function

[Galaxy S II General] It_ler:
I used my results for mixed usage battery tests.

For my current XWLPD system with auto brightness and auto sync of accounts disabled, I had about 30% battery consumption in about 20 hours.

I used this as my reference.

Then I compared this with the results of the same system with the changed setting.

My calculation:

20 hours / 30% (battery loss) * 100% (for the full battery capacity) = 66,6 hours.

That would be the time till the battery is completely empty.

I used this value for calculating the time difference in hours.

And 20/30 equates the reciprocal value of the first factor of my mixed usage battery test results.

And to "normalize" the screen on time rate, I used the last factor of my mixed usage battery test results for calculating the battery time difference in percentage.

I.e. 1,32 => reciprocal value: 0,724 => 0,724 * 100 (for full battery capacity) = 72,4 hours.

The rest is simple "rule of three" / rule of proportion using the above calculated reference values and the test results of the changed systems.
[Galaxy S II General] It_ler:
I don't hate you for this ... at least not yet ;)

Just kidding.

As I only have the 20 hours of my mixed usage battery tests as reference, what else could I have done to "transform" it to 100% for the whole battery capacity of my stock (1650mAh) battery?

The only thing IMO is to re-do all tests, start by 100% battery level and let it run down to 0%.

And that would take a lot of time and all tests to be repeated for that long time.

The only other way I saw, is to extrapolate my 20 hour test results depending on the battery consumption/loss in that test to 100%.

As it was already "mixed usage", I think that a proportional extrapolation is valid.

What do you suggest to generate "better" battery time differences for comparing the same system with changed settings?

I was just using the easiest and most effective way, which came to my mind.
[Galaxy S II General] WhoIsJohnGalt1979:
Thanks for the positive response, hehe. I wouldn't say its my idea, but i remember using a battery calibration app some months back which tells you how much battery is consumed when you use the web for 30 minutes continuously, play a video for 30 minutes, listen to music for 30 minutes, you can add lets say 4 hours of sleep time as in find out the battery drop if u leave the phone idle with different settings(more tests). So now you can do our tests, where in we can see whats the average consumption of battery for these specific activities, you can punch in different kernels, same kernel different brightness settings and what not. What this will do is give everyone a very definite idea as to if they are x battery what of each they can use, more the cycles, more accurate are the results. This way there would be no ambiguity of what things should look like but are for real.

Ps: In the above example the app is doing all the activities, as in plays music, plays a video, opens browser and starts browsing lol with search words like cat bat book shop, images too
[Galaxy S II General] jezus101:

[Galaxy S II General] It_ler:
There are many different battery stats/test/calibration apps in Play store.

I don't trust all these apps, don't want to install to many "battery" apps which consume battery power themselves and I prefer battery testing in real-live usage.

I am using Better Battery Stats (BBS) app and that's it.

CF-Root kernel does not support UV, but as it gives you root access, "tweaking" is generally possible.
[Galaxy S II General] AndroidGX:
Are you sure mate ? I can UV without any problem with latest tegrak's app. But maybe that would explain why I can't see any difference with or without undervolting, don't you think ?

I thought tegrak's module while loaded, acts itelf as a separate module which can accepts UV by his own without any need of compatibility, so maybe I was totally wrong :(

No, it should be possible to undervolt a rooted stock kernel (such as CF-Root kernel) with Tegrak OC app.

Fenomeno83 said something like that after he saw my first battery test results of stock XWLPD.

He wanted to check the battery life on an undervolted XWLPD.
[Galaxy S II General] It_ler:
Just flashed Shun Andromeda 1.8.

After some functional tests, a little bit of battery charging and my first benchmark tests, I saw my first "slow motion" bug.

Very interesting ... I thought that the phone got stuck, but after waiting for some seconds/minutes, it reacts - but very, very slow.

Even after rebooting, the slow motion could not be stopped.

I had to pull out the battery for a while, and now it is back on its original speed.

Will keep an eye on it, if it comes back again.

EDIT:

Very good benchmark results.

Feel smooth ... hope that slow-motion will never come back again.

EDIT2:

Second occurrence of the slow-motion bug is destroying my mixed usage battery test :-(

1. Time I was charging the phone and running some benchmarks.

2. Time no charging, coming from deep sleep and using some apps (internet via wifi).

Have to abort my battery tests !

EDIT3:

Finished battery tests.

Night use is OK, and mixed usage is very good - although there was one slow-motion bug forcing my to reboot my phone.

No more issues so far.

Nice kernel !

P.S.:

Fast Dormancy is a setting in your phone for a special communiation with your mobile carrier.

If it is set incorrectly, your battery will drain faster.

As I saw the FD wakelck in your screenshots, I recommend to change the FD setting on your phone. You can use Fast Dormancy app from Play store to toggle this setting on your phone. (Although it tells you that is is for S3, it works fine on S2 too.)

Look at It_ler tests,he tested stock ls8 and neat lite so you can see his results.I say this because neat rom full is nearly the same of stock sammy rom:all bloatwares and without sale's tweaks(look at neat rom 3d for more info)

I didn't try neat full,but theoretically neat rom lite should be more battery friendly as it doesn't have bloatwares(that drains a lot) and has been touched by sale's magic hands! [Here is only my point of view ;) ]

If you want a clean flash, have a look at THE RED BLUR's cave here => http://xdaforums.com/showpost.php?p=35923600

[Galaxy S II General] dniestre:
What is the kernel that you recommend overall: Philz v4.00-b34 or SiyahKernel v6.0b4?
[Galaxy S II General] It_ler:
Depends on your needs.

There is no universal "best kernel".

And I haven't tested all kernels on XWLS8 NeatROM Lite yet.

PhilZ-touch kernel has best battery life on my phone, with my apps/settings/usage till now.

But maybe it has worse battery life on your phone.

You will have to test it yourself ... on your phone with your apps/settings/usage/etc.

It's a little bit worse than the best result for XWLS8 NeatROM Lite v4.2, which contains a previous version of this kernel.

Maybe "noise", or one of the installed mods (such as live thumbnail video player) causes the slightly higher battery consumption ... or my battery is getting worse.

Will check and compare its batttery life in mixed usage. Then decide what to do next.

Yes, ATM I have kernel result based on XXLSJ and XWLS8 ROM in the first post. (The ROM is always written in backets.)

I thought that the battery results had a significant difference (for the same kernel on the other ROM), but till now, I can see the biggest difference for stock/PhilZ-touch kernels only.

That's why I have not yet separated the results.

My plan was to get more test results based on the official JB ROM (XWLS8), and then substitude the older results based on the leaked JB ROM (XXLSJ).

But now I think about just separate the results and put them into an extra section.

It's nealry the saem as for stock XWLS8 ROM, but a little bit worse than for my previous tests with XWLS8 NeatROM Lite v4.2.

Could be caused by the last mods I installed (e.g. Live Thumbnail video player) or my "old" battery :confused:

Maybe I re-flash the ROM, skip installing the last mods and re-do my tests.

Re: [31 Jan 2013] [KERNEL TESTS] [SAMMY ROMS] Kernel battery tests and benchmark resu

It was on UHLPZ NeatROM and Dorimanx 5.92 all default settings, no powersaving or mods/tweaks.

The best i've got on JB is also 10 hours same as you, that was on LSJ NeatROM but i can't remember the kernel, i think it was jeboo 1.1c with same default settings and no tweaks.

Only thing i do/use is Gemini for autostarts and delete bloatware. No syncs were on either.

I actually prefer performance over battery.

I stopped doing all the battery stuff now though because it got to the point where i was turning all the functions i got the phone for in the first place off.

It just basically became a £10 Nokia that just took calls and texts.

Now i just keep most things on and it doesn't make as much difference to battery as you may think, i still get 5+ hours screen on and 15 hours phone on.

I still use Gemini and delete some bloatware though but not as much as i used to.

I can enjoy my phone more and not be worrying about using it because it would drain battery.

It can get too obsessive! :)

[Galaxy S II General] bobdoblo:
Re: [03 Feb 2013] [KERNEL TESTS] [SAMMY ROMS] Kernel battery tests and benchmark resu

It takes him 20 hours just to do a night test then you have the mixed usage on top of that.

Everyone uses different, i like ondemand + noop, others swear by Pegasusq +sio, it would take forever for him to test all combinations.

Default is what the dev thinks is the best balance of battery and performance ie HYPER + zen and they should know their kernel better than anyone.

It_ler takes into account performance as well as battery with his benchmarks tests. Plus everyone has different usage and settings so its impossible to get the same result on 2 different phones with 2 different users.

So best to just stick to default as a sort of guide to what you can expect with similar useage.

Respect to It_ler for doing this for us too, it must be extremely hard having to keep your phone usage as close as you can to the test conditions and also he cannot flash anything in between or he has to start all over again. ;)

Maybe you could do a test on default then on your governor + scheduler comination and post the differences?

I'd be interested because i have come to the conclusion that it makes very little diffence in changing gov + sched!

So i'd love to see some actual figures:)

*NeatROM*
[Galaxy S II General] It_ler:

As bobdoblo already explained, I prefer sticking to the kernel's default settings.

But if you can show a significant difference under same conditions between the default and your changed governor, then I might get curious and will probably test it myself.
