I'm pretty curious about the Galaga kernel, as I don't hear much about it!

Also, I am looking forward to see Speedmod v28 + v29 (just new) compared to v27, as I heard the incorporating of Samsung's update2 kills battery life :(

If that is true, RAGEmod v1 T27 would probably score way better then RAGEmod v2 T27, as v1 has no update2..

Test update Ninphetamine 2.1.2

Ninphetamine 2.1.2

Display on for 6 hr 20 mins.

Battery left out 56%.

ROM : Litening 6.1

Had a few imp calls and the screen went out for few mins.

Test : Note all test done with Display on at home screen with Go Launcer ex, with Litening background of Android in black/Grey shadow effect that comes with litening. No widgets on the screen except for task manager.

Charging with 2.1.2 seemed faster compared to Speedmod and found it slightly smoother.

NEXT test Speedmod T28, Ninphetamine 2.1.3. Speedmode T29/30.
[Galaxy S II General] xSmooth-:
Well with the FB app removed I now use the phone for over 21 hours!

Seriously I've got it since the release (May) and never got more then 10 hours lol.

Thanks!
[Galaxy S II General] m2smoe:
Good :)

Glad uninstalling those apps paid off.
[Galaxy S II General] zvikam:
Have to agree,

I checked and by using the latest speedmod, the phone never seems to sleep. I switched to 2.1.2 and now it is fine. SPYCPU helped alot to find it :)
[Galaxy S II General] namcj:
You may try Seesmic, it's a FB and Twitter client, it works all right (the app is not very friendly, but at least it saves battery life).

now on LR 6.1 .. Ninphetamine 2.0.2 out

too early to say but I think there is something going on (starting?) with SpeedMod T28. Perhaps it was my uncalibrated battery after flashing to 6.1 but I only got 3h 20 something minutes with my not-so-official test. if there's something worth with update2, you should try RageMod v2 T27, instead. but I'll confirm this sooner or later with my test.

ANYWHOOO.. after calibration, 1st up is Ninphetamine 2.0.2.. I was expecting the same results but didn't, got better. something in KH3 firmware probably? can't tell....yet.
[Galaxy S II General] djvdorp:
Is there any reason why we should want update2? I can't seem to figure out what update2 adds compared to without update2. Sorry if this question is lame.

Nah, I ask this question myself. cant' seem to find some sort changelog.. can anyone point us to the right direction with this please. :)

Anywhoo.. T31 deep sleep issue fix huh.. that's nice. with that, I'll skip speedMod T28-30 tests, probably wait for a final fix on deep sleep issue.. T32?

People all your test exxcept m444266 are not accurate.

Using a black wallpaper will use almost no battery (AMOLED)
[Galaxy S II General] reggaemanu:
Well read the thread...the point of those tests is not to use a black or a white wallpaper but to be consistant between kernel tests (exact same conditions) to see wich one give a better battery life in the same conditions that's all.
[Galaxy S II General] m444266:
grr.. i've tainted my current test. i accidentally locked the phone and forgot for a minute, then i tried to bring it back on track by running stability test for a minute and also forgot about it and had a large drain.. recharging..

btw thanks guys.. and yeah, its hard to be accurate here.. depends on our devices are set up.

"Well read the thread"

Thats a funny way to repsond.

I have read the topic so, if you stop assuming. I am only noting that Black wallpapers will waste close to "No" Battery life.
[Galaxy S II General] goldbergx:
Yes, and for people with dark wallpapers, the guys testing with black wallpapers would probably be closer to reality don't you think?

@m444266: Undervolting by default (speedmod etc) vs allowing the user to use undervolting (Ninpo) is still the biggest chink in the methodology - maybe you can check UV settings of default UVed kernels and apply the same on kernels that are not UVed by default. Simply using the kernels with no extra UVing on kernels at "stock" voltages doesn't prove anything in my opinion.

800 MHz- 975 mVa

500 MHz- 900 mVa

200 MHz- 900 mVa
[Galaxy S II General] rab1412000:
i really like this thread but i feel that the OP has to add UV/UC values to those kernels that support such.

just choose some conservative underclocked and undervolted that you can use across the board.

but i really feel that these uv/uc settings will really complete your brnchmark.

Best battery life ive ever got, all Samsung bloatware frozen in Titanium, with Juice Defender Ultimate and System Panel both froze in Titanium,JD uses as much battery as it saves this is coming from someone who previously was a big fan, im running Cognition 1.51 with latest Ninpho kernel, SepCPU Min 200- Max 800 - On Demand - Profile - screen off - Min 200 - Max 800 - Conservative - about 5 calls (including one 13 minute call) 20 texts, about 90 mins Internet,some music, dropbox 40 files, updating apps and here is the battery life absolutely superb im delighted with this.:)
[Galaxy S II General] goldbergx:
Setting for 1000 MHz looks low compared to others. Why don't you give this a try? Be sure to turn off "Set on Boot" before the attempt

1200 MHz- 1175 mVa

1000 MHz- 1100 mVa

800 MHz- 975 mVa

500 MHz- 900 mVa

200 MHz- 850 mVa
[Galaxy S II General] ithehappy:
Well I don't think its 1000 MHz, cause I didn't change it and got a stable test by changing the 500 MHz and 200 MHz. Here is the actual setting with which I got stable test,

How did you freeze system panel? What app name should be frozen in the list in Titanium?

Thanks
[Galaxy S II General] jonny68:
System Panel is an app i purchased from the market but too many wakelocks so i just froze it alongside Juice Defender, my previous record was 29 hours so by freezing both of them ive managed to get another 8 hours extra :)

Not trying to be funny but what's the point of these benchmarks as they don't reflect real world usage.

not even finished yet with T32 and now theres T34.. :|

That's because there is no standard for real world usage. usage depends on the user. Also, try testing the longest battery life when idle, that will take a while..no..quite a long time..

also when screen off/idle battery SHOULD NOT drain much, if it did, then that's bad apps/settings/configs on your part.. wakelocks?

Yes you're right.. let's leave CPU benchmark scores out and concentrate on battery life.

For the baseband version I'm not entirely how much it would affect the battLife. I'll try to test this one too since there was one who tried KH3 and reverted back to KH1 due to better battery. I'm currently on KH3 baseband so I could probably squeeze it in.

Next up : Shifted to Leomar Rom with Ninphetamine 2.1.3. Currently on Charge - discharge cycle.
[Galaxy S II General] ithehappy:
Four hours won't run cause it loses 1% per minute, so 100 mins/1h 40 mins is max, if you are plugged in via AC the time could get double, still it won't be four hours!

Besides, four hours is way much stressing and not needed.

I recommend 60-75 mins. Half an hour is meaningless, cause I had frozen device several times on 35/36 mins, so one hours is a must. Beside all that, as I said, I doubt Stability Test.

Thanks for the hard work.
[Galaxy S II General] goldbergx:
Honestly, this doesn't prove much as the 5hr 30 min and 5hr 45 min runs were under different conditions - maybe you got an extra phone call or two on the UV setup, maybe you browsed the net for 15-20 mins longer - there are many more things that could be different!!

Case in point - do you get exactly 5hr 45mins display time every-time you let your non UVed phone discharge fully? I think not.
[Galaxy S II General] ithehappy:
Nope, no way one could get a constant Display On time, but it was 5 hr 45 mins generally.

Besides, in that UV test I didn't have any phone calls at all, and the usage was more or less the same like CF kernel. Anyway, I've spent 36 hours behind the UV settings with Stability Test, so I'll keep the UV & Kernel for another day or two and make fully sure about the fact before I go back to stock kernel and non UV settings permanently.

[Galaxy S II General] cptan:
Hi M444266, just a note of thanks for conducting all the tests. very informative and useful for some.
[Galaxy S II General] pspilot:
Well, and why not? UV is a matter of physical laws, no dependency on good code or usage. Just good old plain physics: the lesser the voltage, the lesser the power loss, the power dissipation. If someone's claiming it's not working on his side, he's either living in a parallel universe with altered physical laws ... or he's just not using it right :D.

UV is the most reliable way to safe power, as long as the CPU is running stable with the reduced voltage.
[Galaxy S II General] ithehappy:
From the very beginning it was never about Standby time, but Display On time. And besides, I've posted my result with screen shot which proved things. Now I'd like to see others, I don't believe it, it's simple.

Post a screen shot of battery usage and Display On of your normal life usage with your UV settings and then talk about physics.
[Galaxy S II General] m444266:
Hopefully this week, mate..
[Galaxy S II General] Remoteconcern:
ithehappy, I think I agree with you - the stock (or CF) kernel is the best for battery life. Why don't you try undervolting (with Tegrak) on it? That has been the best for battery life for me by far.

Secondly, I'll agree that undervolting doesn't save you MUCH battery - obviously the display is the biggest culprit. However, you can definitely get a little bit more screen on time with undervolting, maybe 15-20 minutes I find.

Undervolting has other advantages though, like the phone being a lot cooler, and that should have some long term positive effects on the longevity of the parts.

There is really no need to go around posting in multiple threads about how pointless undervolting is though, and having it in your signature that it has NO EFFECT, when the science obviously backs up that it will.
[Galaxy S II General] ithehappy:
Oh come on guys, I just said my opinion. Why on earth would one react on my opinion if he/she is so sure about their own. I don't wanna hear that science stuff anymore cause I've seen what I've seen. As I said, without a screen shot nothing is taken.

@remoteconcern- Now I've no I idea about Tegrak kernel, not sure if I'd give it a try or not. And you are right about the cooler part, yes UV CPU will run cool, but thats good for long term, and I'll use this for 18 months max, so I won't care that. And I got same/worse Display On time with UV and provided screen shot as prove.

God have given us brain and eyes, so I should believe in them.
[Galaxy S II General] L0cutus:
can you posto your actual kernel/uv table settings ?

thanks a lot !
[Galaxy S II General] m2smoe:
Of course UV is going to help you save battery life. And a great deal too, especially while the phone is on standby and you have a low clock profile, with low voltage for it. This isn't a matter of believing it or not, less voltage used = less drain on the battery, period.
