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.
What's good Droid Inc users? I've been working on a charging mod for the Evo that is showing excellent results and seems to prevent the quick drop a lot of android phones get right off the charger from overnight charging. This is just a test kernel btw. Invisiblek added the tweak twice, but the Incredible charging voltages were exceeding that limit, so to save him some time, I've compiled a kernel from his souce and I will be using this thread for testing and once we get it 100%, I'll send him the final code and then he can put it in his kernel.
I would test this out myself but I do not have an Incredible. But this should work for the Incredible because the Incredible and Evo share the same battery drivers. The only thing that needs to be fixed now is voltage limitations. The Incredible can reach higher charging voltages than the Evo. Once we find the right limit for everyone, we'll be all good and your battery life should increase by 1-2 hours (some people have been able to go 6 hours just on the first 10%).
Features:
-Trickle Charging
-Charges extended batteries (and stock batteries) to maximum capacity.
-And everything else that you would find in his kernel
Download v1: here
Download v2: here
my github
invisiblek github
reserved for me
reserved for me x2
Any chance on a sense version of this?
cant wait to test this kernel!!!
Since this is built from his source, it should contain the multitouch patch as well, correct?

Forget charging, what about overheating? Lol the charging is cool though, I'll probably try it out.

It allows up to ten points to register instead of just 2.
Just flashed this kernel running CM #184 will leave it on the charger overnight and let you know how it goes
Which verion of invisiblek's kernel did you use as a base?
I think I am missing something on your github repo. As far as I can tell, the changes you made to arch/arm/mach-msm/htc_battery.c are all in spacing/formatting and not actually altering the code. Can you point me in the right direction here? I would love to try to add these changes into my kernel as well (github), but I am really not seeing the changes...
Any help would be appreciated. And thanks for the great work!
my battery was fully charged before I flashed this kernel, plugged in my charger til the green light came on again(im not bump charging), so with my battery at 97% after the unplug, ive been at 97% for the last 20 mins. Usually by now im down to 90%. As far as overheating...im running at 1.13 as all is fine...soo far so good
Quick question, do you still have to plug this into the wall outlet or can this be charged to maximum capacity through the USB cable to your computer now too? I lost my adapter for the wall so I always have to charge from my computer, which I don't mind.

the charging aspect is great and battery drop is minimal...although, Im having issues with signal bars and 3g it goes from 0 bars w/ 3g, If i have full bars I get 1x instead of 3g...and this will alternate..im using the 2.15 radio...never been an issue before

I like where this thread is going.
1. What is a good app to test the charging current. I use ampere but does not seem to give correct readings.
2. I thought with MM Android allowed monitoring of the charging current. Am I correct?
Thanks

some custom roms for our k3 has fast charging option..like blitz CM13 or AICP 11 and some custom kernel features this too...
what is this fast charging?? is it like Quickcharge?
shouldn't it be hardware based feature?
how fast does this feature charges our device?

Our device originally supports upto 1700mA of current. But in some kernels the charging has been modded to give more current than that. The only thing I don't understand is that they tell us to use the stock charger to get faster charging but our wall charger only provides max 1.7A.
But some people have reported getting current upto 1900mA using the stock charger only. You can test the current through Ampere from play store.
Well you can't say it is like the quick charge technology as in the snapdragon devices but it should lessen the charging time
is it harmful?? for battery? I mean...since our battery isn't designed to cope with such high rated charging....!! is it?

I dont think it is harmful and hopefully the developer of that kernel also knows what our device is capable of

More or less, you should know that you are drawing more current than what the manufacturer specified. This may cause unexpected results like overheating, degradation of battery or worse bursting of phone!
Just be safe
