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.

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 got a new aftermarket battery, same size but more power: is there anything I should do (delete battery stats, manually or through an app, etc...) to have it work properly?
thanks

i doubt its legit anyway..
Your good to go bud the Android system will take care of everything. Wiping battery stats is a thing of the past.

Nothing special to do.
Problem is, if the battery is the same size, its probably the same (or even less) mAh capacity as stock, and just being sold as larger w/ a different label

in theory battery is without NFC so the advertised 1900mAh should be real
is tehre a way to check the real mAh of a battery?
Battery Monitor Widget shows you the mAh of your battery,
By the way, Did you tray to dial the code *#*#4636#*#* on the phone, and then go to the option "battery info"?

As with any battery I suggest charge and discharge FULLY two or three times to condition the battery. Don't top it off for the first bit. If its not genuine, I wouldn't hold my breath. Don't let it sit discharged in your phone lest it leak. My 2cents.
if its the same size as the oem its not 1900mah.
I have recently purchased the Verizon Samsung Extended Battery for both my phone and my wife's. It is supposed to have a capacity of 2100Mah.
However, using the app, Battery Monitor Widget, the app is reading the capacity of both batteries at 1750Mah on both my phone and my wife's phone.
Is this a fault of the app? Can it be possible that both batteries are bad?
If this is all the capacity I am going to get, I might as well go back to stock and get my money back. I just don't want to wait too long and be outside of the return policy from the Verizon store.
Thanks
Reset the battery stats.

No.
Battery stats have NO effect on the percentage or MaH being read.
That being said, I haven't personally tested my extended via that app...or others.
But I generally get JUST A BIT more juice out of the extended.
I'd say it's worth it...especially if you're (obviously) wanting that extra juice...you can just swap mid-day if need be.

Yes, but it's still a good app.
perhaps you can use the program to compare both batteries directly.

I will install the stock battery tonight when I get home, measure it, and report back.

So the stock battery showed up as 1750 as well. I then did some research using the app's help section. I found out you can do a calibration during charge that will determine the actual mah of the battery.
So I ran my battery down to 17%, then turned on the calibration and plugged my phone in. This morning when I looked at the app, it showed by extended battery actual mah as 2022 after the calibration test.
I read a little more, if I run it down to 1 or 2%, it will give a more accurate mah. Therefore, my test for tonight is to drain my battery then run the calibration overnight again.
I will report back my test results tomorrow.
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.

Hi all who stumble upon my question. I recently purchased a 2500mAh battery from ebay but I am having a few issues with my phone/power/charging. Firstly I did a battery stats wipe when the phone was on <1%. Now it always says the battery is on 100% until it dies, even when the phone is offline and the battery is dead it says it's at 100%. This also means that the battery won't charge to its full capacity I have tried wiping the battery stats again once it is charged but unfortunately it makes no difference. Is it because of the rom that i'm on? and i preferably don't want to do a data wipe. I am using the heaven droid rom http://forum.xda-developers.com/showthread.php?t=1801634
Furthermore, i'm finding that i don't get much more usage out of this battery than with the original 1500mAh battery (before i was having this problem...) any tips?
Thanks for reading this, Aaron
Was it an official battery or cheap knock off, if it's the latter I'd bin it and buy an official one.

yeah it was a cheap one but it is bigger and heavier than a genuine ba750 so it seemed legit to me

It is, but the system is locked to 1500 only. After it dies reinsert battery and it would continue the left juice

This is getting annoying now
ok i've kinda tried your suggestion and the battery has been lasting longer. But i flashed AOKP JB and i still have the same problem. Although the battery now says it's at 1%. I performed a data wipe etc. This is getting annoying now :'(

Try this : Download from play store "root browser", open it and go to /system and open file "build.prop" (as text) and edit line :
ro.semc.batt.capacity=1500 (the 1500 replace with your new capacity)!
Then save and close file, reboot phone.
