NFC Antenna is inside the OEM Battery

So after ordering two 1900mah spare batteries from ebay I found out that the antenna for the NFC chip is located in the battery. The replacement batteries I ordered do not have the antenna, neither do any of the other batteries I've seen. So I went to the source Samsung.com and they aren't available for the GSM version only the Verizon version batteries were being sold. So where do I find a GSM extended battery? Or any battery with the NFC antenna inside? As for the batteries I ordered? I guess they'd be fine in a jam but to lose features like beam & NFC is unacceptable for the long haul. All feedback is much appreciated.

A seller named shimshop on eBay is selling 2000mah extended batteries that are genuine Samsung, with NFC. There are many threads mentioning this. I bought one as well.

here's the link,

ships from South Korea so it might take 1-2 weeks for arrival

Something to consider is switching over to external USB batteries. Not only are internal batteries phone-specific (and obviously have NFC issues with the Galaxy Nexus), but there is an increasing trend towards using polymer batteries that are able to fit in unusual shapes but are not user-replaceable (easily). I've got a pair of APC UPB10s. They work with all four phones my wife and I carry, as well as my Bluetooth headset, a host of other devices, and I've got an adapter that lets me use it on my infant daughter's bouncer and swing. I can also carry it in my pocket without a cover (or fear my keys will short it out), I charge it via a mini-USB port (micro would be better, but I don't need a battery charger), and it has a 10,000mAH capacity compared to a spare battery running on the order of 2000mAH. The only downside is that if I'm out of juice I become tethered to it until I can recharge, but a little pre-planning lets me charge in my pocket and it still beats needing to power off my phone just to swap a battery.
Just something to think about instead of dropping more money on batteries you'll end up throwing away when you upgrade your phone.

I actually have three oem samsung batteries, 2 standard and 1 extended, and 1 third party brand at 1450mAh, i've also ordered, but not yet received yet a powerocks 7800mAh external battery.
i wont even need to change out the extended battery, or even use the external, so I dont know why i have all these.

Portable battery packs for Samsung Galaxy s2

I'm going away for a weekend in a couple of weeks and have quite a long journey - 5 hours or so each way - and was hoping someone could recommend a good mobile battery pack for this? Quick look on Amazon and came across these (no link because new member....);
EasyAcc 8400mAh Portable Emergency Universal USB external/extended battery pack
PowerGen Mobile Juice Pack Ultra / External Battery Pack 5200mAh High Capacity Power Bank Charger 1A output
New Trent iCruiser IMP1000 11000mAh External Battery Pack and Charger
Third one looks a bit big to carry around to be honest, like the other two being quite slim, but was hoping someone could recommend anything in particular

Mate ..why dont you try ..samsung 1350mh official bettery pack..its easy and can be used as a case too..search it on ebay..cheerz

Thanks for the recommendation mate, but looking for something a bit bigger in regards to battery life.

I use a cheap AA battery/Solar panel charger when I need to be away from mains power for a while. Maplin sell them for around £13
http://www.maplin.co.uk/solar-charger-388758 <-- this is the exact model I have. Been looking for a way to mount it on my bike now that I use the GPS a lot.

I personally use a Energizer XP8000, perfect for anything and not just the phone.

Thanks for the recommendations. Found someone at work that had the New Trent one I was looking at and didn't like the shape and size of it. Wasn't sure on the Solar one from Maplin and the Energizer one was a little pricey for me. So I've gone for the EasyAcc option i posted - nice, slim and easy to carry

I am using the New Trent iCruiser IMP1000 11000mAh External Battery Pack and Charger at the moment for holidays where i can charge my phone and the gF but looking at swapping this heavy and big beast for the 2800mah pen charging sticks from HK which are so much smaller and ligher plus good quality.

External extended battery charger

I want to be able to get an external battery charger that will charge both the extended battery and the standard battery (both OEM). Will the cheapo external battery chargers on ebay charge both batteries (extended and standard)?

I bought this one on eBay and it will charge my extended (2100 Verizon) and my standard battery.
Hope the link works, if it doesn't, just search eBay for: 200746576954

The cheap ebay ones charge the 2100 fine but don't fit the 3800 sadly. I learned this after ordering mine...

EC TECHNOLOGY 2300mAh Li-ion Battery

http://www.amazon.com/EC-TECHNOLOGY...1347070326&sr=8-2&keywords=anker+battery+t989
I was searching for Anker battery on Amazon and saw this first. I never seen this battery until today and no ones posted a review on Amazon. Its only a bit stronger than Anker but I was thinking about purchasing these just to see how it goes. I've used the Anker batteries before so I'd feel more comfortable buying Anker other than EC, but still wondering if anyone bought these before. Comments?

I bought some EC 1800 batteries and the universal charger and they are OK they last a little longer than my stock battery. They say they don't work with NFC on the nexus but not sure about gs2 because I never use it.
All in all decent product comes in a nice packages, which was nice to not get bulk packaging from amazon.

External Battery Pack for my Android device?

I'm currently looking for suggestions and feedback on and external battery power extender specifically for my Nexus 4, and maybe for an iPad occasionally.
I've been skimming online all day, looking at different brands and models. One battery that seems to fit my needs is from a company named New Trent:
http://www.amazon.com/New-Trent-NT7...qid=1367450278&sr=8-1&keywords=newtrent+nt70t
Anyone have any previous experience with this company and their products?
I'm mainly planning to use this to keep my phone charged when I'm not near any wall plugs or when I'm on vacation.
How much extra charge should I expect from this battery pack?
Any insights on this would be much appreciated.

I don't know about their batteries but they do make some killer micro fiber styluses.
You'd probably get 2 good charges out of that back up pack, assuming their #s are solid.

I haven't tried that specific brand, but I have used a few others. I currently use the Motorola P893 (89536N) which is only an 1860mAh battery pack and I get about an 80-85% charge on my Galaxy S II 1850mAh battery. So if it's anything like this one, expect about 80% of the rated capacity to be actually usable. Thus 7000mAh would translate into about 5600mAh of useable juice. The Nexus 4 has a 2100mAh battery, so I would guess you would get a solid 2 charges and still have some juice left over.
Hope that helps.

Monoprice.com has a nice external pack for a great price. I have one and like it.
I can't post links yet, but its under $29 for a 5000Mah pack.

Interesting, going check this site out

New Trent
I am a beta tester for New Trent and they have wonderful products. I currently have the PowerPak + NT135T. It has 13500 mAh which is huge considering most phones have close to 2000 mAh. I can charge my Nexus 7 (2013) and HTC One at the same time without a hiccup. It's only $54 and can recharge a Nexus 4 5 times.

If you go on amazon and search for external batteries, the #1 brand with thousands of 5-star comments is Anker. I have reviewed every brand of external batteries, and wrote a ton of detailed reviews in the sticky of this Accessory section of XDA (and in my sig link). I have looked at Anker, New Trent, RAVPower, Yoobao, etc... A lot of good trusted brands, but customer support, warranty (18-months), variety, and recent 2nd gen introduction to stay ahead of other cookie-cutter CH generic brands really sets them apart.
