[TUTORIAL] How to prepair battery's for 3.0v kernels

Now that the kernel has been unlocked to alow the battery to use the full 4.2-3.0v potential, some people are having issues getting there battery to drain to 3.0 w/o having its protection circuitry kicking in.
Equipment
Multi meter- digita/ analog... doesnt matter, just need to be able to mesure DC voltage downt to atleat 1/10th volt.
Bulb -i personaly use a #194 automotive bulb
Procedure
drain battery as normal untill shutdown.
remove battery
check voltage across the 2 outer lugs ( just for referance )
take bulb, unfold the wire contacts so they stick out, touch them to the outer lugs ( bulb will barely glow its rated for 12v )
ether tape the bulb in place or hold it there ( i just hold it, keeps me from forgetting about it and draining it to low)
recheck votage every few min.
drain it to 2.9-3.0v
reinstall in phone and charge as normal
some batterys may require you to repete it to recondition the protection circuitry.
if you drain it below 2.5v you will need to buy a new battery... YOU HAVE BEEN WARNED!

Awsome thanks!! Do i need to do this everytime i reflash a eom or kernel thats is able to use this feature?

Li-io batterys need to be drained down every once in a while. Most experts recomend draining to 3.0v about every 30 cycles....

you will only break the battery by trying to drain to 2.5 or below.
3.0v is normal for a li-io battery.
this isnt new technology, were not doing any thing ground breaking. if anything were playing catchup. thank you samsung...

I am still a bit reluctant, however I am willing to proceed with more detail. If you can explain how exactly it works, it will make me feel more confident in doing so. I am not afraid at all in draining the battery with a bulb which I already picked up at Auto Zone, a 194 but this one is a 14v, all they had, and do know how to use a meter, ( am a low voltage installer, go ADT!)
So I was looking for more specifics. How does the kernel then register that the battery can now be used to 3v, etc... If you do know, if not that fine too
Just like to know how things work basically, and how it works.
Thanks!

Which kernels support 3.0v?

Look at eugene's a13 a14 and I think his new one too.

Well just drained the battery to 2.98v and put it on charge now. Cant get it to boot yet, even though after a minute of charging it was back at 3.3 v, Strange? ANyway Im going to let it charge some more and try to turn it on while its still plugged in.

So i have come to the conclusion that all thougj this does work to drain your battery the modded kernel does not work. I have not seen an increase in battery life at all. Which i am very dissapointed in.

Has Nothing to Do with the Kernel MOd... It's the Damn Kernel Clock cycles and sticking at high speeds when sleeping... I've said this many of time already & nobody listens..
OVERKILL Kernel was the First kernel that fixed this issue, so I'm not sure why you're disappointed? the issue was never fixed to start with until now, & even then you only saw a few hours at most with the 3.0V mod..
If it's Reading 3.30v then the Mod is working Correctly as by default it's set to 3.60V, in this case it's just a matter of dropping the Calculations for the battery down a bit more to get the 3.0v setting

Alright, finally someone who knows something about something
Well unfortunately I was unable to read through every post in the forum, but did not know of this issue. Thanks for dropping some knowledge that way I can reflash the new Kernel when I get home and, see better battery life, and watch some dragons.
Hope you didn't take my post the wrong way, by all means you are a legend among the this forum eugene and will always use your kernels, roms, etc.. With that said I might start my own thread to consolidate all of this battery questions, problems, answers etc. Thanks again eugene!!

All good man... I've just stated this a few already is all, lol....
But, with that being said, I know the Mod is working then, and I just need to do a few more adjustment to the source codec and fix a few Calculations to get us down more to the correct settings..
Thanks for Posting the 3.30V though, as this give more to go on, and I was waiting for true data reports before lowering it anymore to keep from brick batteries

Wrong Thread & no it's not needed with the Latest Kernel.

eugene,
So I just flashed the new Kernel, working flawless so far, but am at 60% battery, and have a voltage of 3700 mV. Not sure if that's where the voltage should be at that percentage. You wouldn't happen to have a chart, or know what voltage should be giving what battery percentage.
Should I try draining my battery again down to 3.ov since I just flashed the new kernel?
Thanks

It's based on the init of the battery Calculations.. So if the Calculations are wrong it will report odd until there fixed... Should be fixed in the Kernel I'm running though... Will be Posting the Kernel shortly & now is Marked Stable for all at this point...
Charts? lol, not unless I boot back into linux.. I'll get the charts Posted when I can so everyone can do reporting on it.

Battery Probs..

Battery kept saying 100, but as soon as it was unplugged instantly went to 99.
So i used odin and did the whole nine and charged phone while on had to charge three times back to back and and then it stayed at 100 even after unplugged give it a try..... Hope it works for y'all too!

Where you running a 2.2.1 rom? That battery reating us a known issue

Long way to go for 1%.

lol, some has to have it perfect. ...and yes I'm guilty of that too

Well, if you consider the percentage as being a visual respresentation of the battery's voltage along with a bit of math, then as soon as you remove the charge power, the voltage drops.
It's really nothing like the fuel gauge in your car. Don't get too fixated on it because it's not a very accurate representation of "how charged" the battery is especially at the top, but the 100 is so much better than the stock 10 or so icons... which was more out of sight out of mind.

Yeah I was on 2.2.1. So that drains the batt a little quicker?
Sorry to sound stupid. Still new to all this.

In 2.2.1 there's an issue discussed in the Perception thread where the system apps sync constantly.
Go to Settings->Applications->Samsung Apps and turn it OFF.

An interesting read for you may be the http://forum.xda-developers.com/showthread.php?t=806211&highlight=battery+drain thread. I found this useful when I discovered the issue myself.

In 2.2.1, it's a known issue that battery will jump from 100%->98% almost immediately after being unplugged. According to the kernel gods, and if I understand correctly, it's entirely cosmetic, and is just a change in Samsung's reporting functions. So long as it doesn't continue dropping at that rate, I think you're fine.

Thanks for the info.

My Favorite configuration for O/C

So....long time lurker here....I've tried every rom for the revo, every config setting, every tweak, every update, and so far for speed, battery life etc when running Blitz....the best I can come up with is this:
wipe data/ factory reset in CWM
fresh install:
Gingervolt 1.3
Blitz 2.1
Rom Toolbox Pro.
Toolbox CPU settings: max=1900 min=245 governor=SMOOTHASS
Thats it.
If I go and install scripts....other tweaks....different configurations...they ALL drain the battery faster than that simple setup.
I have the extended battery and I am getting a nice slow drain with decent usage. Blazing fast speed too.
Sometimes LESS IS MORE....and with this phone...after 50 wipes and re-flashes....In my opinion, you will get the best battery life from that config.
I will update this thread with drain % over time...right now I will charge the phone 100% and take it from there.

So...after charging the phone to100%....waited until 3:55pm..then rebooted while plugged in phone untouched until 4:00 pm. I then unplugged the phone and checked battery life exactly at 5:00 ....6:00....and7:00. With ZERO phone use.....the phone....screen off in 4g mode will use exactly 3% every hour on the hour. This is with the settings in the first post.

Thank you very much. Really appreciate it. This works for me too. The Revo has now become very stable, fast, descent battery life. I did it by keeping stock, applying your changes and using Zeam Launcher. Not on Gingervolt.

I have been using the scripts for a week now, and I think I agree. I am sure it's my phone being argumentative. I am thinking of downgrading the supercharger back to the gingervolt, because I think that was the most optimal for my phone, and apparently Mike's too.
Thanks for your post.

next test was to fully charge the phone to 100% ...disable 4g....reboot....wait until 9:00pm andunplug. Again with zero phone usage I waited until 10:00pm. The phone only drained the battery 1%. It went from 100% to 99% in one hour in 3g mode with wifi disabled.
so the next test will be 3g mode with wifi enabled and no use.
after that I will try the phone with wifi enabled in 4g mode
i hope we can zero in on maximizing battery life once and for all.

so one thing i must say regardless of the standby tests.....is that i fully expect garbage battery life after overclocking this phone while i am actually using it. overclocking creates heat......and heat is wasted electricity. so its give and take....sure overclocking is great and the phone isblazin fast...but the battery pays the price.
so theres one thing that is a fact of this phone.....it is 100% impossible to overclock the revolution and get better battery life than what we had before overclocking. its never gonna happen. BUT what we can do is figure out the best way to maximize battery life when the screenis off....and hopefully this thread can start us in the right directiono

You should not see significant battery drain while using the phone. The idea of over clocking is so that multiple apps can run together without there being any jumping or lag. Your processor should not be running at 1900 when in the phone state. We all know 4g is a battery killer. I don't use 4g. This is a great thread you started.

Mine actually charges. I started nav the other day at 81 percent, and ended my drive on 83. I think I was in the car for 30 minutes, maybe 40.
Let's see what duder gets, I am very interested.

Running blitz 2.1 @ 1.9/245 with the OEM extended battery my temps never exceed 90f, monitored by battery ETA. That includes full HD streaming. So, not so concerned about overheating.

Phone running hot and draining battery -what could it be?

Since installing a new ROM, last night, my INCS has been running very hot and seems to be caning the battery.
I charged over night, unplugged it at about 7am and it is is dead already. I haven't been using much more than usual, and so it is concerning me slightly.
I was wondering if anyone could help me find out what is causing the issue and ways to resolve it?
Cheers!

Check the task manager to see what processes you have running. You can also check the battery settings and one of the screens will show what has been using the battery.
Have you tried rebooting the phone?

Thanks for the tips.
Nothing out of the ordinary seems to be running in the background, and most of the battery drain is the screen which isn't too much of a surprise. I don't have many apps installed yet.
Would it be worth installing a cpu monitor to check the cpu speeds, in case it is running too high?
On the stock ROM it would last a good 12 hours with moderate usage and a lot of apps installed and running.

You can try setcpu or whatever CPU utility depending on your rom.
You can set offscreen to a lower speed like 600mhz or so. See if that helps you out.

Thanks, I'll try that and report back.
What are the ideal cpu speeds for the INCS?

I dunno what Rom you're using. But I would recommend you to use all the battery until it shuts down. Charge it to 100% then use a battery calibrater

I'm using Virtuous Quattro RC3 (btw, love it!)
I've charged to 100% and I'll leave it on tonight and see what happens.

Right, I don't know what's changed, if anything, but I left the phone on over night to discharge and it is still at 55% and very cool to the touch.
I guess it just sorted itself out!
Cheers for the help though.

Best mods (Root) for best battery life and phone speed?

I have basically every script/ mod right now done to my Revo and I use Antutu Battery saver running at level 3 (best battery saver level). I still dont feel like I get good battery life, even when not using the phone too much. I have my cpu set on rom Toolbox running 1900/ 255 on smoothass governor, which constantly switches at random. Does it switch because of my battery saver im thinking? Either way, Im trying to figure out if I should wipe my Revo and restart with just Blitz and Rom toolbox for better battery, with still good speeds. Any suggestions if I wipe clean? Or any suggestions on what to do right now? Thanks!

I'm guessing ur using gingervolt... I've had this same issue on my revolution... I've researched it and everything... I've found nothing

I could be wrong but I'm guessing that setting 1.9gHz on the Max is just that, the Max. Not necessarily the "constant" CPU speed.

Now this might not be the answer you were looking for, but I had found that even with multiple power-saving measure my battery-life was still terribly short. The best thing is to get an extended battery, the one for the Revo is beast in size and battery life. Also, since you didn't mention it, changing from LTE to CDMA is also good if you're not really needing your 4G speeds.

Your battery life is probably not too good because of the 1900 mhz setting... I use set CPU and you can use different profiles (including screen off, charging, battery threshold below a certain percent, etc.). This helps, but I don't get great battery life without a program like JuiceDefender. The problem there is, though, that it slows my phone down to the point of it taking a minute to get working, and by that time I have already done what I need to do... sort of sucks.

I got the extended battery too and it is a world of difference. I can run all day and night without killing my battery. Even with moderate to heavy use, I can run through a whole day with no charger (and be comfortable). I just got mine through verizon for 24.99 the other week. I may have overpaid, but I don't trust amazon or ebay too much with some things.

I use 5 different battery programs to monitor my battery and save my battery, but for some reason my battery drains in an hour.
The thing I see on here the most: monitoring programs, 4g connections, flashing left and right. People need to go to YouTube, and watch the video on how Android phones work. They are constantly learning what apps you use or don't use, they are learning how best to operate for your needs. When you flash a ROM or tweaks, it has to relearn. Sure track your battery for a day or two, see what programs are doing what and when, but then get rid of the extra crap, your phones don't need it. If you want extra battery life, get the bigger battery, you all knew coming to a smart phone that battery life sucks. Stop using app killers, and monitoring programs, they run in the background. Turn off auto run programs so one program doesn't start another.

Has anyone measured the battery current? I would think if you are trying all these different setups and use scenarios the actual current draw is what you need to know.

the more programs running the more drain. Widgets are convenient but can be real power hogs. Simple and streamlined is the way to go for me. You can have an awesome looking / running phone by being selective with apps and avoiding redundancies. If i have an issue, i dl the program/s i want to troubleshoot with and when im done i uninstall. No need to use resources that could be used elsewhere. You can always dl the app again or save its apk to the external sd or a laptop or both (thats what i did). Ofc, it will have a new learning curve but settles in a couple days, for me anyway.
