One question;
I have two batteries for my GNex. The original one and a 2300mAh extended one. If I calibrate my battery for the original does that mean I have to recalibrate if I use the extended one? I tend to use a little bit of both depends how much I use it a day, so I can get through the day without charging.

Doesn't matter. There are dozens of pages of debate on the battery calibration front, but official word from Google is that things like wiping battery stats is useless. And most electronics/battery knowledgeable people say that battery calibration is not useful in modern lithium ion batteries.

Hi
I just got my gnex a few days ago.
I come from a vibrant and i had to be calibrating my battery all the time i flashed a new rom.
Do i need to calibrate when i flash a new rom in the gnex?

Thank you. All you need to do is charge fully. Does the same thing as any apps that "calibrate" you battery. Which is delete battery stats. Even then you can't truly calibrate it but condition the battery.

Apps that "calibrate" the battery by deleting batterystats.bin are nothing more than snake oil, as that file has nothing at all to do with displayed battery level.
Any dev that told you to wipe battery stats when flashing a rom apparently did not have a clear understanding of this.
Yes battery stats wipe does nothing, on ALL android phones. Google has confirmed this.
Your question, no there is no way to calibrate the gnex battery. The type of fuel gauge it uses (max17040) has no calibration function at all.
Just to add the Google developer's post:

Lithium-ion/polymer batteries do not need to be calibrated.
Thanks for the info guys

That's not exactly true. Remember the nexus one fuel gauge chip had a calibrate mode inside the ds2784 chip which I learned how to activate. But that's such a rare case. Basically most phones have no calibrate function on the market today.
What is the proper way to condition a new battery? I just purchased the Samsung 2100, and want to make sure I use it properly.

Just use it. Lithium batteries do not need to be conditioned or discharged completely or anything like that. Just use and enjoy.

I bought the Anker battery and it says to deplete the battery fully before recharging it back up to 100% without pulling the battery out of the phone...4 times. It may be a bit much but I wanted to make sure I got the most out of the battery. I believe in it because (i bought 2) one doesnt last nearly as long as the other...I properly conditioned one but not the other.
aftermarket batteries need to be condition like, fully drained and fully recharged.
on the other hand oem batteries don't.
Li-ion/Li-polymer batteries do not need to be conditioned. You are only wasting your time, it will make no difference whatsoever to the health of the battery. In fact letting these batteries run down completely can be harmful to them

You could never condition a Li-ion battery but simply calibrating how the OS logs the battery stats.
That's it.
1-You can't condition a li- on battery.
2- If you could, you wouldn't need to condition a manufacturer's battery.
3- fully depleting any battery harms (and could kill) it. That's one reason most devices won't really allow you to drain every bit out of it (cell phones are a prime example)
4- I've had batteries that I 'conditioned' end up weaker than they started out
5- I never stop at #4. 1,2,3,4,5. 1,2,3,4,5. It has to be done 3 or 4 times.... 5 3,4,5 3,4,5 (just kidding)

I agree but why do you think the stock samsung battery would not need this? I mean it does specifically state in the manual to not use until fully charged. I doubt they are just saying that not knowing what they are talking about.
In anycase like almost anyone who buys a nexus I am way to excited to wait for the dam battery to charge.

The charging cycle is only for the firmware to log the battery stats so it's reflected correctly; it has nothing to do with the battery itself. That's why people recommend it for new batteries - OS will be able to reflect the battery level more accurately.
Like it's been repeated gazillion times before, you could not condition a Li-ion battery. It starts to degrade as soon as it leaves the factory NO MATTER WHAT YOU DO and basically dies within 3 years from the manufacturing date.

I guess that's what I meant. Thank you guys for the responses. I charged it fully, then ran it to shutdown, then charged fully again. So far, so good.

What's up everybody, I just ordered these & hoping they'll do the job. I've ordered from them twice before (nexus one, evo 3d), the batteries in the past have held up pretty good but I don't think these have nfc :/ I ended up ordering these cuz' the qcell nfc enabled ones were sold out/unavailable so I didn't wanna' wait, plus I haven't seen a review on these yet so I said eh, I'll try em' out. If you guys are interested in purchasing some for yourselves I've included the link below, the only thing is that you have to pay using google checkout :/

another 3.7v batter that will die very fast if you use your phone to charge, due to overcharging. as our stock batteries full charge voltage is 4.3 where as that one is 4.2v
unless somehow our phones can distinguish the battery difference,

I always use the supplied wall charger that comes with these so Idk, lots of the extended battery reviews on here are the same voltage & they seem to be doing pretty good.
It's not the charger which matters but the phone itself which charges the battery, it's aiming for 4.3V as that's what it thinks it should have as the stock battery is designed for that. Although I haven't heard a single case of these 4.2V batteries having problems with being charged with 4.3V, that last part can be changed in the kernel and the charger chip driver. I'm getting some knock-off cheap battery myself so I'll see how it goes. This particular one seems quite steep in price @ $30, with proven ones like the PolarCell 2400mAh going out for half the cost.
you won't see the affect right away from overcharging. I use to play with a lot of batteries from RC, overcharging something we use to do get slight edge and boost at start. but it does have long term damage to batteries, specially lithium based. some cheaper batteries even catch fire.
Alright guys, got the batteries in the mail today, charging one & will report back later

Li-ion batteries have an overcharge protection circuit built into the battery pack itself and should prevent this from happening. If everything is working as intended, it should be impossible for the phone to overcharge a battery. That's not to say the protection circuit couldn't fail itself.
And I too played with RC batteries and you really can't compare those batteries with these. Different types of battery with different methods of charging.

Based off of Amazon, these batteries are the same size as the stock battery.
From Amazon's Description: "Standard Size Do not need to change bulky back cover, increase battery life"

Any updates regarding your experience with these batteries? I used to own this brand for my HTC Sensation and was very pleased with it. Almost had about 400+ recharge cycles before the battery started to wear out. Looking forward on your feedback!

damn- not deliverable to my area thru Amazon
Am tempted by the 3000Mah battery by E-Cell....
http://www.ebay.co.uk/itm/GOLD-3000...ultDomain_3&hash=item3f1b24bf0b#ht_2324wt_962
Purchased a 2100mah previously to replace the 1450mah that was in my Sony Xperia Play.... Definately added a few more hours of play to it..... Hmmmm....
I know there are many different ideas on how to calibrate new batteries and how to calibrate batteries after you do a fresh install of a new ROM.
I'd like to create a guide that can be stickied for our s3.
Sourcing all those who helped of course.
I personally just got an anker 4400mAh aftermarket battery but I feel like I didn't calibrate it properly and thus am not getting optimal life.
Post all of your techniques/ideas/opinions in this thread and those we agree on will be added to the OP as the general consensus on battery calibration for the s3.

Charge to full
Run until phone is dead
Recharge
Lather, rinse, repeat.
That's all you need to do.
Pretty much what he said, with the added step of resetting battery statistics by method of choice on full charge before discharge cycle if you aren't confident in your battery meter readings being accurate, or changing batteries. Once will probably work, twice just to be thorough. I have the 4400mah Anker and i get about 8 hours screen on time and ridiculous standby life...like 5% discharge over 30 hours, with some moderate UV'ing through the KT747 kernel btw, just for reference.

I have 2 batteries, 1 stock 1650mAh and 1 MOMAX 1800mAh.
Do I need to calibrate the 2 batteries separately in order to get the best result? Or calibrate once with one of them will get the job done?
You shouldn't "calibrate" batteries at all. Jut let the Gnex function as it's intended to.
063 is right. You don't need to do that. That doesn't have any meaning but using your battery one more cycle. Battery calibration is for outdated generation batteries, not for lithium polymer batteries.
