New battery for Galaxy Nexus i9250

Hi,
Recently my battery stopped charging beyond the 89% mark and now people say that I need to get a new battery. I'm thinking if I should I may go for a long lasting one:
http://www.ebay.com/itm/GENUINE-Ori...ccessories&hash=item2a22467775#ht_2796wt_1397
But I've heard that as the NFC key is encrypted in the battery people have had issues where the NFC stopped working or such. What should I check for to guarantee that it wouldn't be the case with this one?
Thanks in advance for your help.
P.S.: Still for the time being if someone can help with the 89% charge issue, that'd be great.

The battery only contains an antenna for NFC. The actual NFC chip is in the phone itself.

Oh ok! Thanks for the correction guys.
Does this mean that I can safely go with any battery out there? Or the one that I linked?

The one you linked to appears to be a Samsung battery. It will support NFC. If you buy a battery without an NFC antenna, it will still power your phone but NFC won't work.

If you are on Sprint you can call telesales and they will send you the extended battery and door for free just pay for shipping. The extended batt is a 2100Mah instead of the 1850Mah original.

OP is using a GSM nexus, he's from Canada

Thanks guys for all your help. Just ordered the battery from the link above. Hope that it works fine and at least would be a good upgrade from the stock one.

I plan on buying the Samsung 2000mAh battery myself as soon as my current one becomes insufficient.

Well the current one that I have started dying on me twice a day without any drastic changes to my usage. So I think it was a faulty one anyway before this issue started.
Will see how the 2000mAh one fares for my heavy use.

I just tried the battery and it still won't charge beyond the 84% mark now. So I'm now completely confused on what to do with it? Does anyone has any clue? I'm using the Franco Kernel, does it have anything to do with that?
Thanks.

One way to find out- try a different kernel. If that doesn't work, try a factory reset. If that doesn't work, try a different rom. If it still does the same thing, it's time for a new phone.

Tried a different ROM and the stock kernel. Doesn't help. The charging still stops at 89% or whatever random number it wants to. I really don't want to send this back, I just hope there was a way to fix it.
But I think the way back is the only way. Will talk to my carrier then.
Thanks guys for all your help. :good:

Same problem here...
After upgrading to 4.2.1, battery stoped charging to 100%
Now charges to 64%, and if I remove it goes down to 4% then increase around 30%
Not sure if the problem is with the battery.
Tried eveything else aound: Kernels, Stock Brazilian ROM (all versions), Stock Google Images, MIUI, CM9, CM10 and CM10.1
Really sad about that.
Sorry for tha bad engrish...

I have the exact same problem after just 2 months of using this device. The problem first happened when i upgraded to the 4.2.1 takju JOPD firmware! The phone almost goes dead in 6hrs with minimal talk time, and a charge stops at 84%!
Unfortunately, I got this device while in the US from playstore, and now I am back in India. Not even sure of the warranty coz I have rooted this device.
Can anyone please advice?

I'm not sure if this could help, but have you tried draining your battery first (until it powers off) and then charging it to full without turning it on? I've read somewhere (don't remember where but I think it was here on xda) that the battery statistics become more inaccurate over time if you don't drain it to zero at times. I think it's called power cycling which is a good practice to have longer battery lifespan. I hope this helps

Actually, it shortens the battery lifespan exponentially. Full discharge of a lithium-ion battery is unhealthy. Likewise, complete power cycles shorten the battery's serviceable life.
If you suspect the battery's internal fuel gauge to be inaccurate, you could do this once in a blue moon, bearing in mind the unintended consequences.

Why would they give it to us free? I'm buying a G.Nexus this afternoon and a free extended battery would be awesome.

[Q] Problem with SOD? PLEASE HELP

So here's my story...
I hated the new ICS official update that sprint rolled out because of my diminishing battery life. So i decided to finally root the phone and install some roms. Everything went well for the past week but now my phone screen flickers and then my phone shuts off when i still have around 80% battery life left. I try to turn it back on and it loads up the boot screen but sometimes it fully loads the phone and sometimes it doesn't. When it does load ... my battery life is chopped to like 20% or maybe 5%. I calibrated my battery after the flash like someone told me to do but it still didn't work. I thought it was the rom i was using but I flashed 3 different roms and I still have the same problem.
I'm wondering if it's something wrong with my battery or my power on my phone? When the phone is charging it doesn't flicker and shut down on me.
Did anybody else have this problem? Is this considered a SOD? Wondering if I should get a new battery and see if it works. Also... is your battery flat? Mine seems to be a curved a bit in the middle back and front and i don't remember it being like that.
THANKS FOR THE HELP PEOPLE!!!! I really need it

Spin the battery on a flat surface and if it continues to spin, its bad. From your description of the back if battery, it sounds bad. Take it to a sprint store and get a replacement.

This is just the effects of ICS. Go to to your sprint store , they should replace it free. Consider a custom Rom to remedy the issue.

It happened on every rom i flashed.. but this is what i'm on now.
Rom version Blazer FF18
kernel version 3.0.15-sph-d710.ff18-cl663858
Baseband version FH13
I am trying to underclock the phone now and see if it solves any problems till I get a new battery. Realized that while the phone is plugged in... it doesn't flicker and shut down on me. So maybe if i lower the power consumption, it'll work. But it's just an idea I came up with.

Your experiencing a condition that's clearly battery related, while phone is plugged in it clearly shows that the problem is the battery. Making changes and undervolting may just complicate things, I would wait for a new battery before going any further.
You need a proven rom to start with, ask around and see what works for others and give yourself a fresh start. I would recommend going back to stock gingerbread el29,and trying it out for a week or so, then go from there.

Will do. Just ordered a battery. Hopefully it is a battery issue because I am not due for an upgrade yet. Thanks a lot for your advice!

It's the battery, I have the same issues right now and if I use a different battery they instantly disappear.
And you're right about lowering the power consumption, for me it only happened with 4G enabled together with the capacitive LEDs. Disabling one or the other made it go away.

Battery stats RESET at every reboot!!!!!?????

Battery stats RESET at every reboot. Is it just me or is this a JB/Samsung related bug? To me this is NOT normal and it definitely didn't happen in ICS or GB
------------------------------------------------------------------------
:good: Updated Tue, Nov.20.2012
As strange as it may sound, after about 3-4 cycles, the funny issue reported above is gone. Now my SGH-I317M behaves like it's supposed to and so, the battery stats are being kept after reboot. Like all the other Samsung phones I have/had, the battery stats are being reset after the phone has been kept plugged in for a while - which is normal. I took some time to report this just to make sure that it's consistent.

Yeah, I find that annoying too. I wish it kept it's settings. I was hoping to get an accurate look at my daily usage today, but an early reboot is going to destroy that.

Still...I wonder, is this a bug or is it Samsung's/Google's new vision about how battery stats are supposed to be working? If it's a bug they'll probably fix it but if the bug is in someone's head, then we're kind of screwed - from this point onward (JB, KLP, etc)

iirc all stock phones ive had do that. Atrix and the OG note. The note didnt do that once modded tho.

Not quite sure what you mean by "stock phone" but I have the SG2 (SGH-I727R) with ICS 4.0.4, rooted and SG3 (SGH-I747M) with ICS 4.0.4, rooted and DEFINITELY none of them do that. The Note II (SGH-I317M) is certainly my first Android phone to do that - after all, think about it! Is your battery starting a new cycle after every reboot? Plus, the phone might not even get close to a plug. Why reset the stats?

Stock implies just that...STOCK. no root, stock. Dont know what to tell you but both mine did this quirk. Was annoying as hell.
I agree. Resetting is stupid and it would always happen towards the end of the day...before I could see my battery stats lol

I used "Device Analyzer" in the past to see a weeks worth of battery stats in one view. But it only gives you charge levels, not app usage.
My One X resets if I charge it above ~70%. Every android ROM and phone I have had in the past only reset at a full charge. And I haven't seen one yet that resets at a reboot. Sounds like a bug. Fingers crossed for fixing when they push the side by side app view update.
To make sure, we are talking about this data, right?

Battery won't show charge past 70%. Please HELP!

Hi Guys,
I have spent days researching this, and have read dozens of forum posts, but nothing has worked. Here's the problem- I bought a used GNEX off of Craigslist. The phone looks great and seems to work well. But, it won't show a charge beyond about 70%.
I thought the battery might be the issue, so i bought an a new OEM extended battery, but the new battery didn't make any difference. It still won't show a charge above 70% no matter how long I leave it on the charger (with the phone turned on or off). I have done probably 20 discharge/recharge cycles, but nothing changes.
Next, I bought an external charger. When I fully charge the battery in the external charger and pop it in the phone, it still shows around 70%. So, it is definitely an issue with the phone (not the batteries).
I've also tried four different ROMs, as well as all the black-magic "battery calibration" tricks found in the forums, but nothing helps.
I am totally stumped! Is there anyway I can fix this?
Thanks!
Slim

Please HELP! More info.
Hi guys,
Just an update. Yesterday I tried three different kernels, just in case that might make a difference. No luck. The kernels didn't make a difference.
Any advice on how I can make this phone handle battery levels correctly? It's been on the charger all night and only shows 66% charge.

Hey, Reza. How long has your GNEX been having this problem?

You might try returning to stock to see if eliminating custom ROMs helps.

Same issue here, i tried with another battery that showed 95% in other Gnex and in my gnex showed 60%.....
I'm getting crazy!

Definitely a hardware issue.
Toro | Carbon | AK SKL

try an app named "BatteryCalibration" by marosige. When opened it shows the in circuit battery voltage. 3600-3700mV is to be expected from a well charged and in good shape battery. We seam to be having the same issues with mine having progressed to showing 0%. I have a recent thread here as well. I have read that the recovery battery stat wipe is just for the application level, but I think there must be a file or setting somewhere that maps mV to %'s and that this is what needs wiped/reset.

Anyone overhere still having issues?
I updated my thread on a similar if not the same problem, and am looking for some volunteers to help gather a little data. I would like for one or more persons to install SL4A and python, run a script and report findings. If you are willing please post a reply in my thread.
Thank you

BIG Problem

For like the past day or two my phone has been running extremely hot and the battery isnt charging like it normally does. Now it charges extremely slowly, if at all sometimes, and no the contacts are not dirty. I Tried charging it using USB and also wall outlet, ive tried changing the wall "brick" used to plug in my usb cord to higher and lower amperage and voltage but same problem. Now back to the heat problem, Ive tried switching up ROMs, kernels, ROM/kernel combinations just in case it was a kernel and/or ROM problem and same thing. Both problems happen with my 3800mAh extended battery and stock battery. Please if anyone knows anything about this or has any help its well appreciated.

Weird, dude. Well you close to being able to safely assume its not a software issue. But before ruling that out completely I would Odin back to stock; it really does make a difference. Also, can you tell me where the phone is getting the hottest at? Is it just the battery or is it somewhere else?

They may not care, but I personally would try to get back to stock not to chance it.
Also, I most definitely recommend fastboot over Odin. The only time I would use Odin, is if my USB port died and I wanted to get back to stock.
