Hi, I would love to help test these kernels in our quest to squeeze the most out of our batteries. Do these kernels have tun enabled? :)
[Thunderbolt Android Development] GreginNH:
Loaded A and my battery has not moved for 5 hours...

flashed it, made some calls ,texts, several email, twitter and facebook activity and it was at 22% after I flashed it 5 or so hours ago and its still at 22%

Will try B tomorrow
[Thunderbolt Android Development] freebird_78:
3 hr with BAMF 4.4.2 @ 1.2GHz OnDemand:

Average Current Draw: Min - 66mA, Max - 204mA, Avg - 107.33mA

Voltage: Min - 3802mV, Max - 3890mV, Avg - 3850.42mV

Temp: Min - 74.2 DegF, Max - 92.6 DegF, Avg - 83.79 DegF

1 hr with A OnDemand:

Average Current Draw: Min - 56mA, Max - 175mA, Avg - 112mA

Voltage: 3743mV (constant)

Temp: 86.7 DegF (constant)

1 hr with B OnDemand:

Average Current Draw: Min - 58mA, Max - 204mA, Avg - 119.25mA

Voltage: 3738mV (constant)

Temp: 80.4 DegF (constant)

So, relatively small sample size, but the results are fairly consistent. Looks like A is more efficient by about 6%. Not a whole lot of difference, but it's measurable.
[Thunderbolt Android Development] frodsteamin2:
started testing both for a couple hours and phone gets to hot while it just sits around and when i do text or phone call it shoots up even higher. goes up and stays around 100 Fahrenheit for non-use and for usage goes up another 5-8 degrees. Probably just my phone but had to switch it up to different kernel by other, in which it doesn't get as hot.
[Thunderbolt Android Development] froader:
Great feedback. What are you using to show current draw? Does that program also show draw per process?
[Thunderbolt Android Development] 52brandon:
at a higher voltage and temperature too. Odd
[Thunderbolt Android Development] BurnOne77:
I took A and loaded it up on the new plainjanev2 ruu with new radio.
[Thunderbolt Android Development] mcmillanje:
Great idea. Flashing A for results tomorrow.
[Thunderbolt Android Development] DroidDont:
Who's got money on these being identical save for an extraneous setting or two?

I think someone may be trying to prove a point.
[Thunderbolt Android Development] Quantify:
Your min of 58 is high. I think most bolts idle about 34 (I know mine does).

Just did this exercise for the stock kernel. Will report back once I add up all the numbers in the log...
[Thunderbolt Android Development] dsvoda:
That's possible but what is also possible is that he is running a valid test without posting the changes first so that he will get an accurate non biased result. Point is people lie to meet their "wants" so doing it this way will actually let the true results come out. Thank you adrynalyn, keep up the good work.
[Thunderbolt Android Development] adrynalyne:
Looks like the natives are getting restless...

So, it looks like we have a lot of folks leaning towards B. We have test results, folks not having working 3G on one, or the other, and phenomenal battery life on one, vs. the other.

So, these kernels....are

exactly

the same. I compiled both of them, within minutes of each other, with different names, but the exact same files, without modification between each other. Is this a stock kernel? No, it is not. However, and those reporting phenomenal battery life might find this amusing (or angering), they are are STOCK voltage. Both of them!

I apologize for the deception, and wanted to run this a little longer, *shoots the look of death at DroidDont*, but I see arguments starting to brew. This was a test, but not of kernels. This was a test of just how fickle these devices are, and how software, hardware, signal, alignment of the stars, can affect the device one way or another. I've told people before, its not my kernel at fault, its not some other guy's kernel at fault.

All of these current draw tests, benchmarks, etc. They are pointless. They will fluctuate greatly, on the same device, with the same kernel. Signal will vary greatly, on the same device, and adversely affect, or improve, battery life. Undervolting does have a small affect on battery life, but other factors have greater hold, like signal, time of day....(heat will drain battery faster, overclocked or not...), etc.

So, while I could have kept quiet for a few more days, the results would have been similar, I am sure. This too, was hardly a scientific test. I just needed to point out how worthless these market monitors and tests are, and how many more factors than just a rom or kernel play into battery life. Folks wouldn't believe it, until I could find a somewhat crude way of showing it.

My apologies again, and I will not perform a kernel test like this again, you have my word.

On a side note, I will not be updating the first post, because I now have second social experiment. How many read the thread vs. how many just see the first post and jump on it.

Thanks for participating folks.

For any concerns, these kernels were the same as my 4.4.2 standard voltage and frequencies kernel on kernel manager.
[Thunderbolt Android Development] feedhead:
adrynalyne winning!

flawless victory for kernel education.
[Thunderbolt Android Development] bichigo:
lmao you rock :)
[Thunderbolt Android Development] Quantify:
AWESOME! I'm in the market research field...and understanding drivers of perception is a large part of what I do. A great illustration of how personal biases, as well as the larger context, shapes how we experience the world.

Well done sir. I'll be following the posts to see who misses the point...
[Thunderbolt Android Development] cmo220:
Hahaha. I love it!
[Thunderbolt Android Development] Quantify:
So...FWIW at this point...with a stock kernel running for 7 hours with the screen off (while I slept), in a 4G area with 1-2 bars of service, and synchronizing exchange mail once an hour, and sampling current every 3 minutes: Minimum 20mA, Max 388mA, average 50mA. battery dropped from 84% to 69% over those 7 hours.
[Thunderbolt Android Development] wraithdu:
Nicely done :)

Would you mind posting the stock voltage table (I assume the same as what's in 4.4.2) plus the few overclock voltages? I'm having a hard time finding it and I'd like to apply it to another kernel I'm running. Thanks!
[Thunderbolt Android Development] stevessvt:
This thread is made with double rainbows and tigers blood.
[Thunderbolt Android Development] andrew53517:
If some people were getting better battery life with stock voltages, I wonder if it is almost better with stock voltages than having it undervoltaged. Just a thought.

Thunderbolt Rooted!
[Thunderbolt Android Development] jaxon2906:

[Thunderbolt Android Development] dlongb13:
It just shows me that overclocking is pretty useless on this phone. My day to day opperations have been just as fast as before, when running the 4b kernel at 1.2ghz, and my battery life has been significantly better. Also could be due to the new radio and the positive effect it has had on my 4g signal. Either way I will just be sticking with this kernel.

Either way it was a funny test, but I am getting better results, which definitely shows how fickle each handset is.
[Thunderbolt Android Development] Aerogriff:
Nice test man. Regardless, I've gotten about 12 hours on b today(havent tried a yet). Thanks for the kernel, and the laughs.
[Thunderbolt Android Development] Screwbal:
So we good to run this kernel for a while? I saw the voltage was stock as mentioned before and its not OC'd so I'd imagine so.

Maybe its placebo but it seems really fast hows this compare to the 4.4.2 or which one should be more stable and possibly have better battery life?
[Thunderbolt Android Development] pinhead875:
Kernel A is the clear winner here. I tested both for a long time each.

;)
[Thunderbolt Android Development] Nikolai2.1:
Nah man try kernel C, it's hidden
[Thunderbolt Android Development] tcfrombn:
First thing I do when reading a thread is to read the last page, then I read the first post.

Seems backwards, but it helps weed out the useless threads quicker.

I couldn't tell the difference between those two kernels, but I saved a lot of money and had Kernel "B" delivered right to my door thanks to 1-800-pet-meds.
[Thunderbolt Android Development] goater1220:
I've been using (a) for over a day now and I'm getting great battery life
[Thunderbolt Android Development] distortedloop:
Excellent point, well made. Couple of things:

1) Perhaps you should indicate in the first post the same info you did when you let the cat out of the bag to save all the folks who flash before they read the waste of time.

2) I didn't see any clear bias towards B over A in the public posts, but I wasn't tallying either. The one post with all the different numbers posted actually made me think "there's little or no difference, why bother?"

This thread's definitely one I'm going to keep bookmarked to point people at when they get all anal about this kernel that kernel for battery life.

I think I messed this phone up. I was about to sell it and was on Darky's rom. I did a factory reset which after I found I shouldn't have done. It wouldn't boot so I flashed JL2 and now the screen goes black after the boot animation plays.

When I try to format the internal SD it fails. Is it a brick again?
[Galaxy S I9000 Q&A, Help & Troubleshooting] irid:
Yeap... Call Samsung...

Did you disable any lagfixes before trying to flash?
[Galaxy S I9000 Q&A, Help & Troubleshooting] DaveJeep:
First I did the factory reset, then it froze up while doing it. Just kept boot looping in the start up animation. Then I tried to disable voodoo. I left it for a long time and it started boot looping again. I got back into recovery and checked and it said it was disabled. But I was not too sure since it was boot looping.

What if the lag fix didn't disable? Can I fix that?
[Galaxy S I9000 Q&A, Help & Troubleshooting] B-1P:
Flash

Try flashing it again with JL2, have everything selected (pda,modem,bootloader/sbl and repartition / pit file)... try this... it should work.

go into download mode and flash this 3 file firmware with pit and repartition and your phone should boot up

[Nook Color General] RL_Droid:
Hi All,

Newb to XDA forums tough I have been following quite a few of the development threads for weeks now (OC Kernel, Phiredrop ROM, Tablet Tweaks, etc...). First I must say I'm super impressed at all the development being done for the Nook Color, us NC owners are definitely blessed to have an active XDA community full of brilliant developers! :)

But here's my first question about the Nook Color, has anyone noticed that some Nook units have a whiter/brighter screen than others?

Long story short is I've gone through about 5 NC units bc of various problems and have noticed that two of the five units I've been sent so far have noticeably whiter and brighter screens than the other three. This is with the brightness setting set at the same level on each Nook. It might be a color temperature or RGB setting difference between them, but I have no clue how or why they would be different since they were all factory fresh units. Does anyone know if Barnes at some point changed color settings (within kernel?) or started using different IPS LCD parts during manufacturing at some point? I did notice that the two I had with whiter/brighter looking screens had serial numbers that started with 20111, while the others had SNs that started with 2010 or 20110. Maybe they made some settings or parts changes during the newer production runs?

I know a lot of you might be thinking I'm not judging them under the same lighting or that the brightness settings are set to different levels, but I assure you that I am placing them all next to each other and always set them to the same brightness level for comparison. Admittedly, I am a bit particular about how the quality and appearance of my LCD screens, but even my girlfriend who is not a big tech person can easily tell the difference between the screen by looking at them from a few feet away. She instantly picks out the one that has whiter whites and appears "brighter" (again with brightness set at the same level).

Of course if you don't have two of these units next to each other for comparison it might be hard to see the difference relative to one another, but I can assure you the screen whiteness differences are there between some units. Wondering if there is any way for us to control these settings via kernel changes or some other changes (color temp, hue, RGB)? My problem is that I currently have a perfect unit that has the dimmer screen, and a brighter unit that has a dead pixel and am trying to decide which I should keep and which I should return. I actually prefer the colors and appearance of the one with the whiter screen but get distracted knowing there is a dead pixel. So it's a tradeoff. However, if i know I can change the colors of the screen and make the good unit look whiter/brighter down the line, I will definitely keep that one.

Any thoughts/advice would be much appreciated.

Thanks!
[Nook Color General] cowballz69:
anyway u can post a high def video of this? would help on what your seeing. my nookn color is def a lot yellower than my other devices. but never saw a nook that's whiter than the other
[Nook Color General] RL_Droid:
I can try to take a video tonight, but not entirely sure if the color/brightness differences will be captured on the video but i'll give it a shot.

I tried not to use the term "yellow" in my initial post since whiteness level is relative, but that's basically how my gf described it - "That one looks yellower than that other."
[Nook Color General] bradputt:
yeah, i find whites on my nook very "yellowish" compared to my phone.

too bad there's no settings to change the color temperature on the nook.
[Nook Color General] RL_Droid:
Actually, that was one of my questions. Is there any way to change the color temperature of the Nook LCD screen or something along that line via the kernel? I have no clue about kernel parameters, but was hoping someone like Dalingrin, the resident kernel guru, might be able to answer this question? I think I've seen some ppl create apps to update color settings in the kernal for android phones.
[Nook Color General] richardz88:
I have an NC with serial number started 2004, which has very beautiful screen, but just three dead pixels. so I called B&N to have a replacement, and yesterday, the new one arrived (serial number 20112..). When I have both devices sitting next to each other, I can instantly tell the new one is VERY VERY yellowish (or say, the color is way too warm).

I have to call B&N to have another replacement, and the representative told me the yellowish is a known issue, though happen rarely. My personal experience can tell that even the newer devices may still have the yellowish problem.
[Nook Color General] RL_Droid:
There goes my theory about newer serial numbers. Have no clue why some units are yellowish and some a nice white then. But so far out of all the units i've got the ones that had whiter screens all seemed to either have dead pixels or some dirt or other particles stuck underneath the glass, and the ones with the yellowish screen seem to have no other screen defects. Probably luck of the draw, but I've got some pretty bad luck so far then. Love the NC, but I'm thinking the quality assurance is pretty shabby at this point.
[Nook Color General] a.fenderson:
Sorry if this is OT, but this is the part of your post that most caught my attention. What the hell are you doing to those poor Nooks? ;-)

But seriously--what the hell?
[Nook Color General] RL_Droid:
Lol... as mentioned, two had dead pixels one of them the pixel were dead center, one had dirt under the glass, another had a loose back and a yellowish screen. Now trying to decide which of the two I have left to keep. The one with one dead pixel on the right side but a white screen, and the other that has a yellowish screen but no other issues at all.
[Nook Color General] cowballz69:
I hear u with the yellow tint. had this next to my bros Ipad 2. and the nook was embarrasingly yellow. and my apple fan boi bro said it looks like a macaroni n cheese screen.
[Nook Color General] pixeljunk:
Our first had a definite "yellow" tint to it. VERY hard to notice, but I seem to notice every imperfection. Exchanged it and the second looked better. A friend of mine bought one and it had the same yellowish tint. Doesn't bother him though. Says he doesn't see it.
[Nook Color General] matt310:
Are you running the stock rom/kernel? I know on CM7 there's definitely a more yellowish tone to the screen than on Nookie Froyo or the stock rom.
[Nook Color General] robot8:
Didn't realize there was such inconsistencies with the NCs regarding color temp until I read this thread. Without being able to compare screens I have no problems with mine as it seems pretty good to me, serial 2010xx dated Feb 2011.

I guess I was lucky that the one I bought had a good screen without a single dead pixel. That was the only thing I checked as it was the most important thing to me. Couldn't care less about any other cosmetic issues. Build quality was better than I expected for something of this price, but recently the left side of the bezel has started to creak annoyingly when I hold it.

Definitely can't compare to those tablets twice it's price. But AFAIC, it works very well and with the phenomenal dev support, a Nook running CM7/OC can't be beat.

If I were you, I'd return the one with dead pixel. Built into CM7 there is "Render effect". Besides the night modes, there are some basic calibaration profiles in there. Maybe one of them might make your screen a bit "whiter".

edit: I just checked and it seems all the N1 profiles made my screen seem warmer. I suppose a few more profiles can be implemented, perhaps you should start a petition to the devs? :P
