Non OEM battery upgrade

Has any purchased an additional battery for our ATT (i777) from a vendor off Ebay or Amazon? I've seen a some 1900 mah batteries advertised by merchants stating they will fit the international and AT&T variant. Anyone buy one yet for our ATT model?
 
I been looking for one too but the stock battery has NFC in it and I doubt a generic one would have that in it. Be careful though of those cheapies, go for a trusted brand like Seidio
 
Considering that NFC is not enabled on the ATT phone, I'm not banking on the fact that it will be functional anytime soon. I'll look into the Seidio brand. Thanks. Hoping to get a few more opinions. Maybe i'll be a guinea pig.
 
Yes, I bought two batteries and a charger off eBay. I bought them for days I'd be away from power with heavy use.

The batteries work fine, but will not charge in the phone. The Galaxy S2 recognizes they are not OEM and shuts off the phone if you attempt it.

I think my $12 purchase will serve its purpose. I'm happy.

Can you name the Ebay merchant you purchased the set from? Or a link?
 
You will have problems charging those non NFC batteries while they are in the phone with the USB charger.

Phone will end up in a infinite reboot. The will probably charge out of the phone and power the phone but will give you hell if they are in the phone and you try to charge them while in the phone.

Have not seen any NFC extended batteries on the market as of yet.

there's a thread someone on XDA in the GS2 section where someone actually looked into the batteries and basically it was determined that you need to get a battery that is designed for the i777. If not, it will not stay powered on when you plug it in.

i used a seidio extended battery with my captivate that trippled my battery life, but it added a hump to the back, which was worth it. as the galaxy s 2 is new, seidio, a respected manufacturer, does not offer it yet. however, i feel one extended battery is the best solution compared to the hassle of having a dock charger and/or several stock batteries to charge.

when seidio offers an extended battery, i am sure people will post it in this forum.

UPDATE:

called seidio, and no date for their extended battery for the galaxy s 2.

however, only via the web, i found a company outside los angeles, and although the back cover is shiney, and will show some scratches over time, i think i am going to gamble and try it out. i can put some small fuzzies from home depot on the back, but i want more battery life, period. i will update this post after i get it and try it out for a few days.

Looking forward to hear your experience. I guess it is somehow bulkier than the OEM, which will make it impossible to use my case. :(

From some of the other forums, the SGH-I777 (AT&T) battery is NFC and sports an internal antennae and will somehow charge *slightly* differently than a GENERIC after market brand that was earmarked for the SGH-I9100 (international) Galaxy S2 without NFC.

What's the difference as long as they both fit?

Well it does fit, and when either batter is installed on the SGH-I777 you will be able to utilize your phone, HOWEVER, if you plug your phone into a USB cable to charge the *GENERIC* battery, chances are your phone will shut down and restart. I believe the circuitry is different in the generics that do *NOT* support the NFC circuitry...

Just curious if you wouldn't mind posting *AFTER* you received you new battery if the battery can be charged in the handset with the USB cable or will a seperate charger be required... Potential deal breaker for me...

:(

FYI - The URL and SPECS that CaptivateMeNow posted states the battery is a replacement for the I9100 it doesn't mention the I777 and the battery part # is wrong type for the AT&T model... The correct battery type for AT&T is:

EB-L1A2GBA

Thank you in advance!
 
I actually contacted Seidio to ask a question about their cases, before reading this post. They said the extended ATT Galaxy 2 battery should be out soon, and that they would have the appropiate sized case for sale at the same time, and it would also fit their desktop charging cradle. They did say they are waiting for enough requests before manufacturing their rugged moisture/dust resistant over-case, so let them know if you are interested in one (I sure am).

Well it does fit, and when either batter is installed on the SGH-I777 you will be able to utilize your phone, HOWEVER, if you plug your phone into a USB cable to charge the *GENERIC* battery, chances are your phone will shut down and restart. I believe the circuitry is different in the generics that do *NOT* support the NFC circuitry...

This battery will not charge in the device. I'm sending it back.
 
I bought 2 generic 1910mah batteries (red) off of Ebay...came with wall charger. This particular vendor said in the add that they WOULD charge while in the phone and plugged in via USB.

I received the 2 batteries I had spent about $33 dollars on and neither one would charge in the phone...it would instantly reboot. I brought this to the sellers attention who said he would immediately send me out 2 more batteries.

Well, I waited...and thought...they won't work either.

I recieved them both...and both of the replacements do in fact charge while in the phone!!!

So I now have 4 batteries...2 that charge in phone and 2 that don't. I simply marked them with a sharpie to know the difference.

I already ordered the official Samsung Battery and dock station for about $37.00 + shipping 1 week ago... Couldn't believe the issue about the *GENERIC* batteries not working with onboard charger... I saw this auction for the past few weeks but was sitting on the fence until someone from the forums found it working and without issue... Last week I couldn't wait any longer... too bad you didn't post this up earlier...

Bottom line, I liked your post (THANKED!) and liked the auction so much I placed an order for it as well...! Wow, just like you I'll now have more that THREE (3) batteries to play with! :D:D
