[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.

Suddenly bad battery life = battery gone bad?

Basically, a few weeks ago I flashed assonance 5.0 and my standby battery life was terrible. The battery would die by the time I got out of school which is around 7-8 hours of standby time.
So hoping to solve this problem. I flashed the captivate version of doc's rom and I have the exact same battery life. I have recalibrated the battery many times as well.
Sooo, do you think my battery has gone bad?
And if so, any good places where I could get a spare?

Many have posted eBay has some good deals.
I still suspect that many of these phones were shipped with crap batteries hence the differences with people using the same roms having much different battery life.

Have you at least tried reflashing to stock to see if the problem is with the roms or with your battery?

Not for an extended period... but the thing is I read through some of the rom threads. And if it was the rom people would be complaining about battery life, but no one is :/
In fact, it is quite the opposite...

kernel related or bad battery!!!!

Well i am using Glitterball's latest kernel before Firebird. Or the stock kernel that came with the Doc's Captivate Rom 7.0
Either way, there has been a huge drop in battery life and I do not think it is kernel related, because on the Assonance 5.0 rom, i was running Setiron's 1.4.7 kernel with the exact same problems with battery life :'(

This is highly dependent on how you have your settings on your phone.
1) Wi-Fi constantly looking for an active network connection? At least have it go to sleep when the phone goes on standby. I only turn mine on at home or otherwise need and have access to it. Otherwise its off.
2) GPS running all the time? Personally, I rarely ever need to use it, but it runs great when I do.
3) Display at recommended brightness or higher? Recommended or less is best as far as saving battery power. I like mine all the way down. Don't need/want it any brighter.
I even tend to use only darker wallpapers as bright and lighter colors pull more power on AMOLED screens. This makes a little bit of difference. How much I don't know, but I do know that it does. Sometimes the above settings like to change on you. It's a good idea to check 'em once in a while.
While it's usually always around 60% full when I go to bed, I still charge my cell every night.
I have found that the speedmod kernel is real good for conserving battery power. Not downing other kernels as they're all real good. Speedmod handles battery consumption better in my experience.
Have you installed any new software that might be accessing the network checking for updates/feeds, etc?

1)I always had my Wifi sleep policy on never. So its not what is affecting the battery life
2) Never have GPS on unless i need it. Heck, when i need it, it never works.
3) nothing that i didnt have before.
Basically, I haven't changed anything to cause the decrease in battery life.

Your two biggest drains on battery are WiFi (especially when consistently seeking - any new access points where you leave it on standby all day?) and your display. Could it be your battery? Sure. Go exchange it at AT&T. They shouldn't have a problem exchanging it for you

[Q] Randomly resetting N1 - possible solution

I just bought a nexus one with the old resetting issue that seems to have come up a lot.
I've been stress testing the phone (using StabilityTest) and found that the sure way to get it to reset is to heat it up, by charging it, stress testing for a while (usually a few mins), putting it on a hot water bottle ect.
The temperature in these cases usually gets to around 30 C before it dies.
I put it on some frozen milk and sure enough its been stress testing for half an hour with no problems - the temperature sticks at about 15 C.
I'll try opening it up and cleaning everything I can with isopropanol. I figure maybe there's some gunk preventing proper cooling?
Any thoughts as to what else could be causing this?

Might be defective or degraded CPU.
Heat slows down electric signals, and the CPU is built to withstand a specific amount of heat without failures. If in the manufacturing process somewhere in the CPU there appears too small (physically) semiconductor or metal layer, it won't withstand the heat. Moreover, heating/cooling cycles destroy material slowly - and one of those layers could be marginal when manufactured, and pass the tests, and later get partially destroyed - and make the CPU prone to overheating.

Have you applied the 2.3.4 update?
This was supposedly a bug fixed in the 2.3.4 update...

Thanks for the replies.
Jack_R1 - sounds like a good theory, it's a shame theres no way (that i know) of checking whether the cpu is making errors like in prime95. I can stress test it but all I know is when it crashes. Presumably if the cpu is degraded it will be messing up alot.
Another theory I read about was that some phones where shipped with a fault in the main pcb that is supposed to reset the phone when it gets too hot as a protection measure.
GldRush98 - I will give it a go, I'm downloading the latest cm nightly which I presume is 2.3.4 - I had read that the reset fix was for nexus s phones though?
I've just treid undervolting the kernal, it might not fix it but it could be stable enough for most things. An undervolt of 75mv managed a stress test of 20mins which is a record without ice...
EDIT: StabilityTest does report errors. I just haven't been getting any, would this mean its not the cpu?

I think you're right, that fix was for the Nexus S.
Sorry bud

Same here.. It mainly starts after update the radio. If you check the last kmsg you'll see that it's the radio which crashed.
If I use my phone during charging, it resets all the time.
What I read is
* May be a hardware issue that HTC can fix (but my phone have more than one year so...)
* May be sim card issue. I'll change it tomorrow, will see.
I've never overclocked or overvolt my cell, mainly under clock to 960 and undervolt, so I reckon it's not our fault.
Sent from my Nexus One using XDA App

Its not a sim card issue for me.. Its been crashing without one in. Maybe worth disabling the radio and testing like that?
I just tried overvolting my cpu by 50mv and it seems rock solid. 1 hour 30 on stabilitytest without a crash and while charging. I'll keep testing and let you know. Might be worth a try if your willing to overvolt. Useful links here:
http://forum.xda-developers.com/showthread.php?t=1059423
http://www.tiamat-aosp.com/downloads/tiamat-n1/

so, if i understood this correctly, and to solve my random reboot problem..i have to flash tiamat-kernel, and then PSM +50 Nexus One file????
i am running cm7 rom my n1 is unlocked.

That's what I did, but I've no idea why so no guarantees. Another point is that it probably won't stop reboots entirely.. I put my phone on a hot water bottle and left it stress testing - it rebooted.
Should make it pretty stable for normal use if you don't live in a desert though.
Let me know how you get on.

i just installed the tiamat kernel i am thinking of trying it out before flashing the psm file

Sounds good. Maybe the fix was the tiamat kernal not the overvolt...
I've spent half the day fixing my phone after I somehow destroyed it in testing - left it on the hot water bottle stress testing too long. It decided to reset and then get stuck on the boot screen no matter what I tried to reflash.
Just got it working again now, running cm7 and tiamat (without ov) to test...

the tiamat kernel alone didn't help...i flashed the psm+50 file..i will report back...

Yeah, didn't work for me either, I've also tried insectRavens kernal to test and no difference there. +50 still seems to be radically more stable for me.
Something I did notice is that the default smartass governor used by tiamat slows my phone down, I've changed it to interactive using setcpu which seems to be about normal speed. Might be worth doing...

Sorry to say this but psm file didn't help me either

That's a shame. Ah well, maybe something particularly weird is going on with my phone. Seems to be fixed anyway.

I changed my SIM card, with no effect. I'm using the last redstar kernel and found it more stable but when charging. It's quite better, but not as good as I would.. sadly.

SLCD Nexus one 35°C then... reboot or freeze some ideas
Hi to everyone.... very interesting thread. I'm an owner of 2 nexus one, AMOLED and SLCD the first one is perfect the SLCD have overheating issue it was bought second hand on ebay it's a vodafone espana.
I've noticed that it's working perfect till its working temperature become 35.6°C i.e. 96.08°F. It can freeze (need to remove battery) or it reboot but freeze on colored cross logo. As soon as I shutdown it removing battery and try to power, it vibrates 7 seven times.
Searching on the web seven times vibrating is CPU working bad for bad temperature. Anyone has tried to disassemble nexus one and putting thermal paste on Snapdragon to reduce overheating and better heating dissipation?
For sure for better stability we need to overvolt but we need to eliminate overheating maybe also modifying plastic on the back of the down side of nexus one.
When I bought it, it was winter so anykind of issue now I need to shutdown if overheating remove battery and wait some minutes.
Stability test apk it's not a problem I can use it for one hour and half without issue using tiamat kernel vipermod plus +50mvolt with setcpu on demand with maximum of 422-466-499mhz for cpu frequency.
The real test is running Angry Birds Rio try playing with it (with full frequency 998mhz without tiamat kernel and vipermod I can play only some level maybe 10-15mins) with this kind of configuration I succeed playing for one hour and half before first reboot.
So Angry Birds is the real test (hoping that it has anykind of bugs ) maybe that physics calculation are written bad or are alots and cpu overheat.
P.S.
Anyone opened it putting thermal paste?
P.P.S.
Sorry for my english I'm from Italy hope I have been clear.
P.P.P.S.
Sorry for long post.
Best Regards
Tony

I finally send it back to HTC, for reparation. Costs me 55$, and 2weeks after, my nexy came back.
Since, all work. HTC changed all the main board. The nexus can go through 100°F without any reboot. So maybe you can do that, but it seems to be much more overheating :-/

[Q] Increase battery performance on Optimus x2

What is the best way to increase battery life on LG P999 Optimus X2?
Model: LG-P999 (Wind Mobile Canada)
OS: 2.2.2
Baseband: M6600A-SCAUTNZ-2.0.9.972T 1
[JUL 15 2011 10:00:00]
MP:TRULGLE_08.09.02R_MDM
Kernel: 2.6.32.9
Build: FRG83G
Software: LG-P999-AWC-V11h
Rooted: YES
Or would it better to put on a custom ROM instead that looks identical to the current stock?
I am not sure if this battery issue maybe due to the fact that I had O2X installed and then flashed it back to a backup copy I got from XDA-Dev but ones again not sure, it just seems battery now die's even faster then it used to with STOCK firmware without CM7 and O2X

Isnt that a g2x
http://forum.xda-developers.com/forumdisplay.php?f=1114
Otherwise I am happy with battery performance on Miui 1.11.25

I don't think so since its 2x is also P-999 unless it P-900. I heard Miui lacks some features and has problems dealing with stuff like MMS and others.
Would still love to reduce battery usage

Your phone is a g2x as its real name p999 proves it. Canadian providers falsely renamed it o2x.
O2x is p990. Nobody had the unique solution for battery. Too many factors.
As hardware, kernels and ROM are different, you should ask on g2x threads.

LG optimus X2 (P990) battery charging
Hey guys I bought my LG OX2 a month ago, and I do have a few phone/tablet chargers, one for my blackberry, one for the kindle fire and one for my LG-OX2. All of them have the same connection, so I thought i will keep my Lg charger at my office and use my kindle charger to charged my OX2 at home. I was using CM7 and i had no problems at all. A few days ago I flash it with NOVA HD+ and first couple days charging over night with the kindle charger had no problems but after that in the mornings my phone is completely shut off. So i have to take the battery off and back on to start it. This morning i notice it again but the battery was empty, so i connected again and after 20 min was doing fine but after 40 min the phone shut off again completely and was very very hot specially where the camere area is. Anyone knows if is because I'm not using the original charger or is the new rom NOVA HD+.
Any suggestions?
Thanks!

It shouldn't be the charger. All micro USB ports should have +5V on their power terminals (this is the USB voltage from your PC USB port).
EDIT: You can refer to this link
http://en.wikipedia.org/wiki/Usb#Power
EDIT number 2:
Unless, of course, your charger is defective.

Well yes you're right is not the charger. As i just connected to the lg charger and after 15 minutes i check the phone and was very hot and unable to turn it on. So I had taken the battery out to cool it off for a few minutes. What else could it be? I don't remember or changing or doing any tweaks.

I've seen a lot of complaining about exactly the same thing as you. I would try flashing temasek's latest kang and vadonka's latest kernel, which should be among the most stable ROM/kernel combination out there for O2X.
If you still get SOD (sleep of death) while charging the phone, it could be a defective battery, or a defective phone altogether. In which case I would suggest that you try to flash your phone back to factory settings and ask for a replacement.

I appreciate your input. At this moment is charging ok, no heating, no SOD (SOD hehehe funny). I have download it the latest NOVA HD+ and i think i gonna give it another try. If continues heating up while charging I will take your advice (although flashing temasek's latest kang and vadonka's latest kernel sounds more complex work for a newbie like me. Do you know if there's any tutorial to follow?)
I will post the result after the update.

It's very simple. How do you flash NOVA? Isn't it through CWM? Flashing temasek's kang and vadonka's kernel is exactly through the same method.

The first time I flash NOVA was thru rom manager. Last night i flash the latest NOVA (which seems to be a new version almost everyday) http://hei1125.hopto.org/Nova HD (CM9)/
And I did it thru recovery mode, this time I wiped cache and delvik. And seems like everything is working normal. I did charge it over night, no heating, no SOD, is working flawless. Camera, clock, email working fine, browser now works on landscape which before wasn't. Video still not working. (ooopsss as i'm testing the video the phone kinda crashed and i had to remove battery to reboot it).
But so far so good... I hope stays 'stable'.

Glad it's working better for you now
How do you test the video? I can record video and play it back without any problems. I can also play youtube videos. Never had problems.

I open muy camera app and click on record video and the apps shuts down with a message "sorry the camera was closed because of error".
I can play videos on YouTube without problem.
So for a couple times the phone has gone frozen and the only way to reboot its by removing the battery.

I have found the solution to the poor battery life on the wind mobile G2X.
The culprit is the stock battery. Get rid of it. I was getting less than 3-4 hours battery life from mine with everything I could possibly do to reduce the battery load.
I purchased an extended battery off e-bay. It is the identical physical size, but has 1950mAh.
I now get well over 24 hours battery life. Over 10 hours playing games/browsing internet.

A lot of discussions about aftermarket batteries in many forums (here i guess, too).
If there is a print on the battery like 2200mAh, actually it doenst mean anything. You can be lucky to get a higher capacity or maybe get one with less. Dont believe in the sellers claim

battery performance
in the market you will find same aplications like battery maintenance-very good for battery life

Nexus 4: 16 GB, Optimus G: 32 G
Nexus 4 Latest updates, Optimus G: very slow updates( I meant very slow), and every small developing community ( i meant really very small)
Nexus 4: no LTE, Optimus G: Supports LTE (in india LTE not available)
Nexus 4: no USB OTG support, Optimus G: (Supports pen drive mouse keyboard u name it)
Both devices have reported back cover crack issues and over heating issues. Please provide your views on this.
Both looks good.
Howz gaming performance?
Nexus in india is 25k where as optimus g is 30 k.
So which one to go for.
Currently using Incs for almost 2 years, awesome build quality and pretty good developing community.

Well if I'm not mistaken the nexus 4 is based of the lg. So with that in mind I'd go for the nexus 4.
Nexus 4
Cheaper
Latest version of android
Not sure if, but will probably get 4.3 version of android
So go for the nexus

Correction. So yes, I would suggest the Nexus 4. Its got a nice big developer community too.

I thought you could turn the optimus into a N4 with a mod on xda
No joke

Yes we can convert n4 to og with a mod but lg abandons there devices once new device is out. Lg g pro is out.. Og2 is about to come.. So og will be a history. Very less development support.
FYI: the phone is available from august 2012 almost a year and just 38 threads in development section

getting an incredible s
hi guys, i need some opinions here
i'm thinking of getting an incredible s, as i got bored with the hd2 already
i liked incredible s because it fits right into my hand, and i liked holding it. here are my questions:
1) how is the phone? is it still fast for today's standard? (i'm thinking of using sense 4.1 roms)
2) will the speed of the rom increase if i use class 10 cards? my freind used a class10 on his nexushd2 ics and he said there's a noticeable
performance jump, but im skeptical
3) will there be any issues if i used sun global batteries with custom roms? i heard a while back that third-party batteries aren't compatible with
custom roms
thanks for your time yeah?

The Incredible S is a great phone but I think that in this current time and age, you can do a lot better.
For question 2, ummm, there is certainly the possibility but I think it would only be faster in regards to the activities related to the micro sd card. I think someone else should help me here. :laugh:
For question 3, batteries don't affect a ROM's booting and compatibility with custom ROM's. They are just batteries (like the stock one HTC gives you) that provides juice for your phone.

because i don't want to spend too much on a phone. besides, incredible s is pretty cheap in my area nowadays. i haven't used any proper android phone before. HD2 was a pseudo-android phone :laugh:
umm... so do i have to do any battery calibrations if i used third-party batteries?

You shouldn't need any additional calibration.

You always need battery calibrations after flashing a new rom as you flash a new rom, old battery stats are still in your device and thus this can affect your battery percentage.
As a new battery is already calibrated, it is not advised but it wouldnot make a difference unless the battery is too old or of low quality

They are not always necessary. 80% of the time when I flash a new ROM, I don't bother with wiping battery stats simply because it does not make a notable difference in battery life or readings whatsoever. I only calibrate battery if and ONLY if I know that I'm supposed to be getting better battery on a particular ROM

Seriously?
How many times does it take for people to realize that wiping battery stats is probably just as useful as trying to unlock the screen by screaming at it?
If you need the sources for why the battery stats doesn't matter at all, just look through my earlier posts Google it. I'm currently on 2G so it'll take ages for me to find it.
(No, not trying to sound hostile or anything, just tired of people still wasting their time on wiping the battery stats)

After flashing a new rom, there are always chances that some stats from previous rom are left and this could result in quick drainage of battery. Battery life isnot improved or made better by this, however, sometimes due to flashing roms, the battery percentage is messed showing wrong percentage all the time. Thus, Calibrating a Battery is a better than waitng for battery to settle down.
"Better performance and battery-life is why most of us turn to custom ROMs. We keep trying from the available ROMs and stick to one that meets up to our expectations. Now there are two ways to find out how the battery performs- with the help of a battery monitor app (stock or third-party) and by taking note of the battery performance during the hours of a day.
If you feel that your device is not yielding good battery just because the battery monitor stats show it, you might be wrong in your judgement as most such apps sometimes lie to us.
Remember that with any ROM installed on your Android device, you will discover two things: 1. battery heat up, and 2. battery drain. And these issues for the most part are due to process of your phone’s new software and battery sync. It usually requires 3-4 full-charge and discharge cycles before things go to a normal state and after this, you will notice great improvement in battery performance. So, do not be quick in concluding anything about battery.
Let the battery calibrate and while you wait try one more thing. Whether you get a new phone or new software on your old device, avoid putting your device into charging mode frequently. Turn off the phone, plug charger, wait till it is fully charged and then use it till it is fully discharged. Repeating this several times will improve the battery-life of your device. I have tested it and it really works. "

Calibrating as in fully charge and then let it discharge to <5%, yes. As in removing a file which only saves what apps used how much battery, how the *beeeep* is that supposed to help your battery?

whoops i mistook battery calibration as wiping battery stats :silly:
but yeah, honestly, my battery rarely falls below 30%. Im more of a go home then walk out a couple hours later so charging from 5% takes a bit too long. Thus I never do battery calibration. In addition it doesn't really do anything. Battery does not improve to a noticeable point where its actually worth the 5 or 6 hours wait to charge the phone :/

5-6 hours to charge from 5%?! Occasionally I kill my battery (it's actually good to do that once in a while) and it doesn't take that long to recharge for me
Do you use a cheap charger with like 500mA output?
