Extended battery - AT&T Samsung Galaxy S II SGH-I777

I found this on e-bay & it says not compatible with the nfc chip. My phone doesn't have that right? Also, what do you think the chances of this battery boot looping? I already have 3 that do. Does anyone know of any on Ebay that don't for sure? I saw the post for the Amazon one but I don't want to spend 30 bucks when I can get free shipping on Ebay.

That'd be nice if only it would charge in our phones, but since it'd probably give you a boot loop it makes no sense to get one since it doesn't even come with a wall charger to give it any juice.

I got a wall charger with the other 3 regular ones that boot loop.

That seems to be the same as this ones.

I have the Hyperion Version.. and been very happy it doesn´t boot loop.

So this one won't boot loop? I might pick one up then as it'd be nice to have the battery and the case

Cool. If you could take pictures of what it all looks like together, that'd be great too!

I just got it today. I tried to charge it with my charger from the other batteries I got & it's reversed so can't charge it that way. Its in my phone now & thankfully does not boot loop. I'll try & get some pictures up soon.

3500 mAH worth it?

I'm thinking about getting an extended battery for the vibrant which is 3500 mah and I was wondering, is it really worth it? Because if I put it in my pocket I really don't want it to stick out or get annoying. Any comments or opinion's that may question my choice are welcome that will help me in my decision.

If it's Samsung original, it won't stick out. I tried one at an official Samsung distributor a while back and it looks exactly the same as the stock one, feels heavier though.
WAIT! You can buy a battery that holds more charge???? How much is it?
I just received my extended battery and I couldn't be happier. My phone has been off the charger since 7 this morning and with heavy use it just got down to 60. (over 14 hours)

[Q] Help with CWM recovery [FIXED]

Hi, I need help. I used Font Changer (root) from market, and i screwed something, and my phone stucked in the boot logo.. So i tried to reinstall ROM (alien) but my recovery (the newest one, i think CWM 5.0.26) can't mount sd card. I was trying it so much, and now, my battery is discharged, so i can't even try to flash rom via fastboot.
I know, i know, i did it wrong, i'm dumb and what so ever, call me how do you want, but please, help me!
You need to charge the battery or get a factory cable before you can do anything

Any chance to charge battery without having factory cable or other battery? (I havent any friend with the same phone...)
Anybody knows?
Buy one of those desktop chargers that you just plug the battery in. They are cheap....

How do you usually charge your handset?

Maulich: Ok, thanks... But I thought if there isn't some mode in Atrix that I can charge with... But it's probably bull****
Baz Scotland: By normal wall charger, but my battery isn't charging, I always stuck at bootlogo, and when I wan't to reflash, recovery write: E:/ Can't mount SD card and in fastboot mode says: Battery is too low to flash
Ouch I feel your pain, I expected the battery to charge if left switched off, best solution would be to purchase a dock that will charge the battery when removed from the handset, I've seen a few on ebay.
Only problem is having to wait for delivery.

Less than 5 bucks on Amazon.

Amazon sounds like your best bet, they usually delivery pretty fast as well.

Ok, thanks I will buy the battery charger, but on ebay. I am from CZE and amazon doesn't ship there and i have good experience with delivery from Hong Kong (about 3-4 days and for free).
Thanks for help.

Charging cradle W/ Extended Battery Charger.

Hi,
I just bought an extended battery that constantly boot loops when plugged into AC so instead of trashing it I decided to get a charging dock that could charge out. Anyone know of a dock or cradle I can use? Thanks!

I just these batteries from Ebay that included a charger, good thing cause they all boot loop on me. Why is it these cheap batteries boot loop like this?

Just bought a 2200mah external case

I just bought a i9100 external battery case from ebay not sure if its any good or it fits but I'm going to give it a try any ways. Has any bought one of this.
UPDATE"""
OK got the case 2 days ago and was going through the cycle charges to get the full potential out of the battery. The case fits great with no freezes or boot loop when on. Cons it kept turning of and on by its self, but fixed that by bending the usb plug. OK second con is the battery life sucks it would only charged the phone up to 65%. So what I did was open up the case to see what size battery it was and it says 1700mah not 2200mah liked stated on the case.the battery is crap and I wont recommend it to any one. I'm going to try to take out the old battery and put in a better battery..

my note not charging while am using it. does any one has the same problem? ?

Hi guys i used to have galaxy s2 before i bought the galaxy note.my s2 used to charge in the background even though am using it.but i found note dont charge the battery when am using it.i dont think this is a special feature samsung gave it to customers i never saw a device having this type of issue. Is anyone having same problem. Is there any solution for this. Thanq guys
That's because the phone uses more power than the stock charger provides.
This is normal, but you may have better luck using a different charger.
How long have you had the phone? And are you using the stock wall charger?
Sent from my SAMSUNG-SGH-I717 using xda app-developers app
Are you using an overclocked kernel? If so, that along with high brightness setting and using the stock charger could cause that to happen. plus it takes a few days of full charging amd discharge before the battery is calibrated.
Am using it from 2 months.am using original charger.

I had the same problem. If you get the wire at the AT&T store that is a charging only wire it seems to provide the phone with 1 amp of power from the original charging block. Or you can buy a wire off eBay like I did and it does the job.

Which ebay seller? Many sell bogus charge only cable...
Download current widget https://play.google.com/store/apps/details?id=com.manor.currentwidget&hl=en
Use a 10 divider and if the widget shows 990-1000ma then you're good as far as the charger.
Now even with 1000ma chargin, if the screen is on, playing music, and navigation. It will either stay the same charge or charge very very slow. (very)
CobraCables... I purchased 3 six foot charging cables. One was broken and the seller asked no questions and sent me a new one. All cables come with a 2 year warranty and are high quality.

I recommend a 2A charger like the HP Touch pad unit. The phone only draws as much as is needed. It also come with a good quality and thick cable.
