To prove the efficiency of undervolt do this test yourself.

Run Antutu benchmark 10 times without undervolt

Run Antutu Benchmark 10 times with gpu/cpu undervolt.

Why run Antutu? Because antutu use all frequency of processor and use gpu too, simple.

Start the two tests with full charge (100%) and see your battery after the tests.

[Galaxy S III Android Development] MuertoKo:
Sorry to disagree here but it doesn't look like proper testing to me, Antutu results are hardly influenced by heating of the CPU. That makes them erratic and different one from each other, so how can you say it's same drain? For me it's not good enough... If you want to run a test you could try what I did months ago for the same stuff, UV.

Do 2 tests, same as you say, with and without UV using as condicionts: Fresh reboot, open media player and reproduce the same FILM, for me it was Avatar as it lasts enough to drain my battery full, and well, I don't mind watching it for a few times! Do this while in Plane mode all time, to avoid any interfere with internet conection (even standing on the same spot you can experience way different drain depending on environmental factors for example!).

Doing like this you wn't see any interference, you can record the behaviour, CPU and temps using System Tuner Pro or just by watching your device all the time it's running (well, or at least when you expect it to drain!).

For me this is only way to proceed on proper testing, but I hadn't any idea on how to track on-live and ge recorded the CPU-temp when doing this, so I have to find a way to test about heat/cool with and without UV.

For me, about battery turned to be null efect doing this tests on 2 devices, been fighting UV for over 1 year now on Sensation lol :P

As soon as I get the time, and I'm really short, I'll try to do this and post results wherever they are wanted about heating and consumption ones again, or if you like my method and want to give it a try (and know how to track the results on a .txt or kinda) could be nice if you have the time and will to do it :D

Anyway, thanks for sharing your point of view about this :) Like chating about this!

---------- Post added at 01:13 PM ---------- Previous post was at 01:07 PM ----------

Let me add that this was tested on Nexus S, CPU is way different :P Still, 2% makes some sense as I got 1h36 without UV and 1h38 with hard UV... that's near a 2% and in my testing it was screen ON all time, useless and risky to me just for 2%, but if it helps on cooling the device, then might be worth for me, and I'll try to test that if I sort out how and get the time to do it properly!
[Galaxy S III Android Development] harunjo:
they using hardware to test it....so its quite legit..

the problem is they are not testing with pegasusq.

but if they test it with s3 device i think the result will be not much different...

edit: ups..i was wrong they are using:
[Galaxy S III Android Development] eric-filth:
Sorry, but im not agree with you too hehe

You doesnt like antutu because dont burn enough? And you like testing running films because burn?

Just run antutu 10 times and check CPU Spy after, you will see used same frequencies (time for each freq), but varied.(200, 400, 500,...).

Resuming.

Run Antutu and will you see the processor running at each frequency, and each gpu frequency but always identical. The only way to "trust" is to do this test is running one by app/bench identical every time and just Antutu can do this because the test because the test is always the same.

But you want to test running Films? You checked the cpu frequency used and each gpu frequency used? For me, executing film the processor will be always fixed at ONE frequency and the GPU too.

Thanks Mate..please have you Changelog for this 2.0beta4r2:cool:

Thanks

[Galaxy S III Android Development] habylab:
Don't bother with UV, can cause problems people report on here that are not needed. The voltage is set for a reason, clearly.
[Galaxy S III Android Development] drdoulittle:
Okay thanks Mate...:good:
[Galaxy S III Android Development] MuertoKo:
Just the opposite my friend :) I'm writing at work so kinda ninja-writing, my bad maybe!

I ment that Antutu causes the phone to heat up, causing random results, each time you run Antutu you have some slight difference, maybe a little one but still there is!

The aim of testing is trying different voltages in 2 exact same situations. On a film you have GPU and CPU fixed to a freq, so if you have that freq UVed you can clearly see the effect of the UV!

By running same film, you ensure to have exact same CPU load, GPU load, freqs, heating (if rested properly between testing) and ofc same brightness and color levels on the screen :)

And after seeing my results look similar to the ones harunjo posted I'm quite sure my method is quite trustable (feel like I'm inventing this word, but hope it makes sense lol). Same "2% gain on battery" experienced on my previous testing :)

Hope I explained myself better this time!

About heating, I ment that I'd like to do some tests recording the CPU temperature, to check properly if UV affects the device tempreature in a noticeable way, so to make it worth

[Galaxy S III Android Development] eric-filth:
No problems i respect your method.

But i dont agree test the undervolt with gpu/cpu fixed because dont represent real life... antutu always do the same test every time, trust me :)

Using Android and playing games the frequency always be different (gpu/cpu) and closest thing to this situation is antutu.
[Galaxy S III Android Development] brunodu91:
thank you

but too complicated and too dangerous for me!

never mind
[Galaxy S III Android Development] davi_ssilva:
I understood your arguments, but I think you're paying attention to the wrong thing here: it doesn't matter if antutu is affected by the heating off the phone, because what's being discussed here is battery consumption, not benchmark performance. And since the tests that antutu executes are always the same, even at different cpu temperatures, the consumption for each test will be the same every time, although the bench results will surely vary. So I think that Eric's method is pretty accurate if you want to measure battery drain. Also, using antutu forces the phone to do a more varied amount of processes and functions than the ones that are demanded by just watching a movie, so I think it's a more comprehensive test.

Sorry to not agree here either:

http://batteryuniversity.com/learn/article/discharging_at_high_and_low_temperatures

Nice article btw, as most on that webside. You want to test something steady, and the only way is to keep it cool, at same temperature and same frequences, not jumping one to another...

Anyway, won't keep discussing this as it's getting to a deadend... test however you like :) We all (ok, most of us! don't want to offend by saying this in int. forums, just a common spanish expresion) live in free countries :D

Will leave you enjoying your extra 10% bat with UV, I can't get it and seems physically imposible, but if it works for you then go ahead ofc!
[Galaxy S III Android Development] eric-filth:
Andreilux did some undervolts tests using multimeter and the results was amazing.

I trust him and myself.

For me, discussion ended, and lets keep kernel focus again :cyclops:
[Galaxy S III Android Development] MuertoKo:
Can you share link? Afaik he implemented some sort of interface aplying different voltages acording to your CPU version or kinda...
[Galaxy S III Android Development] davi_ssilva:
Nice article indeed!

But by reading this article I started to think we've come to a dead end: if battery drainage changes so much with the working temperature, so maybe we'll never get a way to precisely compare undervolted devices with stock voltage devices, just because the simple fact that UV devices work in a lower temperature. So even if we make a test using antutu or if we make a test just watching a movie, we won't get the real drainage for comparisson, because an UV device will be doing the same test in a lower temperature than a non-UV device.

But I agree with you, it's better to stop this off-topic chat before we end-up changing the purpose of the thread! Cheers!

Hmmm seems like I'm having Wi-Fi issues at home with beta 4 r2. Back on beta 3 all is well.

Linksys e4200, 802.11n 5KHz.
[Galaxy S III Android Development] harunjo:
what issue?
[Galaxy S III Android Development] chargen2:
For additional testing, I just flashed v2.0 b4R2 again and after a few minutes it seems fine. Not sure if it just needed a reboot or what. sorry to have cluttered the thread with something I'd not confirmed first.

The symptom was:

With wifi on, traffic works initially, then just stops passing traffic. I can turn wifi off/on and it will work again for a moment. If I don't turn wifi off and back on, Android will eventually disconnect from wifi and use 3G data. (Does it detect if there is no internet connection available through a wifi network?)

I believe it was fine when I was at work on the 802.11g, 2.4GHz wifi network there, but I wasn't watching it closely.

I put v2.0 b3 back on and don't seem to be experiencing the behaviour any more. I can't determine if the reboot while installing the kernel may have reset something.
[Galaxy S III Android Development] harunjo:
thanks for the detail report.

i will wait for your further report..
[Galaxy S III Android Development] hshah:
I agree, I am experiencing the same WiFi issue. The WiFi works for a bit and then the phone switches to 3G... like right now for example, I should be on WiFi but it's not.

[Galaxy S III Android Development] drdoulittle:
harunjo

I find v2.0beta4 better and he also runs better than v2.0beta4r2. The accumulator in v2.0beta4r2 is not so good, so more consumption than still in v2.0beta3 and beta4. Besides, I had 2x reboots in v2.0beta4r2 with open the App.

The App is compatible and posed no problems with beta4.

I find the Scheduler (deadline) not so tingling and will start again beta4.

He was a little better however for it it is to be reworked also beta and therefore no problem r2 over again.:cool:

Thanks for your work and hope you go to the older beta4 Performance back!
[Galaxy S III Android Development] harunjo:
fyi beta 4r2 is same like beta4

i released r2 because i forgot to include deadline scheduler..

with r2 sio is still default scheduler, deadline is optional.

if you dont switch the scheduller from sio to deadline then it will have a same performance character like beta4.

did you switch it to deadline?
[Galaxy S III Android Development] Sad56:
Someone report in my forum, he also have two reboots with R2 when he choose Deadline :(

Personally, I stay with b4 and have excellent battery life :)

1day 12hours with 4 hours screen on (with wifi) and still have 47%.

The only things for me, don't know if it's due to Sio, but when I go directly in applications manager from home (with Nova) for example,time to open and to charge the list of apps is longer, and transitions seems less speed.

[Galaxy S III Android Development] drdoulittle:
harunjo,

I can agree only Sad56 while what he writes and I write.

We want to inform only of the best and try to understanding why it so serious differences gives between r2 and beta4.

It strikes me immediately if I another Kernel takes and the next day uses the phone professionally, because I make a lot with the phone, Internet, Telephone calls, Wattsapp, Mail, Bluetooth, GPS, Data, Wifi etc.

If I have 2 reboots because I an App wants to open, then I do not know what is right because it has not appeared before with the same App. Accumulator is much more consumption, litheness and crossings are not so liquid as with beta4.

Hence, I am on beta4 back, because you have solved the CRT out of vision problem and the Kernel beta4 simply smoother runs and is in the accumulator much better.

Okay you are the expert, take r2 over again under the magnifying glass and please time leaves you.:cool:
[Galaxy S III Android Development] hur8111:

Harunjo this kernel is getting better and better...

With v2.0 beta4 R2 (with SIO enabled), im getting smoother system with awesome battery for my day to day use.

20% left - 1 day and 4 hours on (3G on full time and Wifi sometimes)

Screen on Time - 2 hrs +

Calls - 1 hrs +

NFS Most Wanted - 1 hr +

TB - 30 mins

Texting and What's app etc etc....

Rocking like nothing ever before buddy, keep up the good work.

All in all i think having deadline and SIO together would be fine for future also.

Sadly still I couldn't do a test on deadline to tell the difference, sooner i will.....!!! :D

@Sad56 nice and thanks for your Report!

I'm ready to take off beta5 now!

@So of the Kernel runs and I have opened just fast all Apps and none reboots.

I have closed the Apps and have opened, did not make several times behind each other and none reboots, also with the App in beta4r2 problems.

No flicker in the screen with close about power badge.

Thus runs of the Kernel surely smooth, but it is to be said too briefly now already more. I will see next Day, if I the phone in the continuous operation have and will report in the evening with pleasure.

What I find, however, now quite great that the Kernel is so stable and does not want my phone rebootet without I!!

Once more good work!!
