I have installed perseus kernel and stweaks. Is it safe to increase Dcp and mains ac input current and dcp and mains ac charge current to 2000 mA?

Theoretically it is safe upto 2100mah. But Samsung must have thought something while setting it to 1700mah.
this is XXXDDDAAA
Samsung in his infinite knowledge must have also thought of something when it declared rooting as "illegal"
But we know better!
So should i increase it?

Upto you. I don't think it needs any increase. As I said theoretically upto 2100mah should be alright.

So if I increase the phone wont go kaput!?
Will the phone charge faster?

Well the charging speed should increase.
The charging Current and battery life(I mean hardware, life of the battery) are theoretically indirectly proportional. I mean to say is chances are your battery could die faster then it should have.

This is a stock kernel for GSM Galaxy Nexus 4.0.3 with the following properties:
Root access with adb (a.k.a. insecure)
Charger is modified to stop charging at 4000mV and > 80%, and start charging again at 3990mV or < 80%.
Rationales:
Stock kernel: I value compatibility and stability. While the various mods and new features are undoubtedly very useful for many people, some of them are not well tested which results in lower stability. That is not to say stock Android is extremely stable (it is not), adding new features on top of which very often increases the likelyhood of crashes.
Limited charging: As a developer, my phone is virtually plugged in the computer all the time. As many of you are aware, leaving the phone charged greatly reduces battery life (Ref). This kernel frees you from having to unplugging and plugging in the phone repeatedly in fear of destroying your precious battery.
Visible differences:
Charging percentage will not increase after the phone is charged to 80% or more.
The phone never reports full charge, even if it's charged while being turned off. That means battery stats can accumulate which, after a while, makes it practically useless as the diagram is too compressed. This is a plus to me as I can see how I manage the battery over time, although I can make an alternate version which reports full charge whenever the phone stops charging under requests.
Perhaps I'm the only one who is paranoid about keeping battery charge between 10-90%, I wouldn't be surprised if no one is interested it this at all.
The kernel can be flashed using Odin or fastboot. If someone wants a CWM-flashable zip let me know.
Cheers.

Glad to know I'm not the only one. When I was using the SGS2 I spent quite a bit of time looking for such mod to no avail. Searching for "android|galaxy nexus limit charging voltage" turned up lots of posts about changing kernel voltage which wasn't what I wanted.
I like to keep the kernel close to stock, but thanks anyway .
Hey, an idea to you devs: what about a apk that schedules the charge limit? for example, if you use to charge your phone at night and you wake up at 7 that app could charge the phone @ 60% and at 6 start charging'till it reaches the 100%
With ezekeel BLX mod it should be easy to schedule modifying the file, but i have no idea on programming nor cron

You can do that with Tasker, it is a bit on the heavy side but saves having another service running in the background while leaves the possibility to do a lot more. I'm not aware of other light-weight but user friendly solutions for managing scripts, perhaps others could chime in.

agree with ezekieel...his Battery Life eXtender (BLX)do the same thing(via file /sys/class/misc/batterylifeextender/charging_limit default 100),without give up at all the tweaks,oc,color control etc. try that if you want.anyway thanks for the work,personally it not interest me,but certainly someone will find it usefull!

Not much to speak of tbh. Here is the patch. You can build it from the stock branch 4.0.3_r1 . I changed the compilation flags so it better matches Cortex A9 but I'm sure there are rooms for performance improvements.
GLaDOS kernel has this value configurable as well so aside from being stable, this kernel is worse all around .
I assume you meant 4000 mV, not 4000 mAh? Considering that not even extended batteries I've seen exceed 3500 mAh?

Greetings gentlemen! I've been testing wireless charging with Galaxy Nexus and Nexus 5, and while I like the technology, I'm not comfortable with two side-effects: higher battery temperature, and higher average battery charge voltage. I'd like to work around this by limiting the charge capacity to 80% / 4.0v.
I think the lost battery capacity will work for me because the way I'm using the wireless chargers is keeping the batteries topped up all day. By keeping wireless chargers by the bed and the main work space, the phones hardly ever run down! But this also keeps the battery at 100% constantly. Thus my 5-year-old bright idea to limit the voltage!
What's the state of the art of this problem solution? Should I ask a kernel developer to include https://github.com/Ezekeel/GLaDOS-nexus-s/tree/blx ?
Maybe this question has been asked for many user.. but I need more clearly solution. My Question is simple.
Which one the best method to change our #GNote2 battery?
a. Charge it whatever have a time to change
b. Change it when our #GNote2 said that we need to charge our battery
c. Always Change until it FULLY CHANGED... and never remove charger cable before battery full.
Or any the best method?
Thanks

No more battery memory right now .
Of coz you can use your phone battery to under 20% then charge it back to 100%
But it's not easy @ note2.
Everyday I have around 30-40% battery leave when I charging.

In his defense, I have had several phones where the charging port eventually got flaky and I also kind of worry about this slightly. This includes the note 1.

That has nothing to do with the battery and everything to do with being careless when plugging or unplugging.
OP, you may want to google or wiki the latest battery technology. Those 'tips' (b) and (c) you mentioned were good for NiMH batteries. Nowadays, we use Li ion or Li polymer batteries which do not need to be fully charged and discharged to maintain longevity.
Sent from my GT-N7100
Two things are important for prolonging your battery (lithium based) life: charging level and depth of discharge. avoid charging to 100% as much as you can, and also avoid wide discharging range.
A good strategy is to charge what you use, that is, if you use only 50% of the capacity every day, then only charge to 80% and use it down to 30%, then recharge.

Ive never heard 'avoid charging to 100%' .
I dont understand how that could be harmful.

It isn't. It's just more FUD about batteries... *sigh*
Listen people. It's -really- very simple. There are no tricks involved. Just drain your battery how you like and charge it how you like. These phones are designed for average people in mind. People who don't have a CLUE about having special discharge/recharge routines. They're designed to be charged whenever the user wants to charge, to 100% or not, as the user likes. The hardware within the charging circuit and battery itself will protect it from harm.
By how to maximize the battery life I mean the life of the battery itself(1-2 years) not how long it lasts(1-2 days)?
I've read that if you charge your battery to 90% it is better than to charge to 100%. Is it true? I mean that if you use your battery a lot it will die in 2 years. But is there a way not to kill your battery this fast. I am using Air Kernel and CM10.1 so I can set the battery to charge only to 100%(default), 96%(as stock) or even lower.
Batteries last much longer than 2 years even without you changing anything. No reason to bother if that's your goal. Just avoid extreme hot and cold temperatures and water and it's foolproof.
most likely, your battery will outlast your device.
But will it be bad for the battery if I set the maximum charging to 100 rather than to stock 96%?

since 2008, ive always charged my devices(android) to 100%, even leaving them on the charger much longer. ive never had a battery problem. needless to say, none of my devices has ever outlasted the battery.

OK, but the stock battery capacity that Samsung have set is 96. I believe that they have a reason for that. But the kernel's default is 100.

Complete cycles do negatively affect the lifespan of the battery, but most folks will have moved on to another phone by the time the battery is to the point of being unusable.

The battery controller doesn't appear to report current, so there's no way to get that in software beyond conjecture based upon reported battery level.

Thanks for the reply. That is sad news.
What should the p6 battery voltage range be?
myne is 0% at 3.5V and 100% 4.3V
As fas as I know, li-pol batteries should be from 3.4v - 4.2v.
Or am I wrong? Maby the battery voltage goes to high and thats why my battery is swelling?
(I used CPUZ to check voltages)
Yours is too high.

No, rooting the phone is a good thing. Just install SetCPU but be careful when you use it.
And just how setCPU would help ?
I think there's nothing wrong, for me it's more probably a false reading from the software side/app. Or you have physically measured the voltage, which I doubt.

so its a defected phone, caus all the apps say the same voltage. so the phone itself reads wrong, or simply charges to high. aniway.wednesday I am giving it in to get it fixed.
ps. I have setcpu, but that controls only the cpu, not battery. wont help here.
Thanx alot for the help guys. Will se you in a month again.

@benna, did you have unusually rapid battery drops after reaching 12%? I'm experiencing drops from 12% to 1% in a matter of seconds and the battery calibration apps I've tried are reading a similar voltage (slightly higher than 4,3 volts) when fully charged. In fact, the phone indicator won't stop showing 100% after it is past 4,2V threshhold. I'm forcing calibration at 4.2V to see it fixes it.
