here is my Neo Hybrid EX in Infinity White

I have a video on my website
[AT&T Samsung Galaxy S II SGH-I777] zanson:
so, how long dose thing thing take to charge back up?
[AT&T Samsung Galaxy S II SGH-I777] Alucardis666:
That's an awesome deal, thanks for sharing
[AT&T Samsung Galaxy S II SGH-I777] sdas683:
About 5 hours.. It all depends what kind of wall USB charger you are using, I found that the iPhones USB block with my cable works the best (Output 5vDC @ 1.0A).

All depends on what you feel is necessary, really wouldn't recommend anything much more powerful than that..
[AT&T Samsung Galaxy S II SGH-I777] shinshoryuken:
I just got this battery(thanks HTC Chris).

at my house I get poor reception but with the external battery it seem to make the reception even worst. I used an app called opensignal and it seem to confirm it. Do anyone else notice a drop of reception with the battery?
[AT&T Samsung Galaxy S II SGH-I777] stickbo:
That's odd. Find a table somewhere in the house and go to settings >about phone>status see what signal you get with the stock vs the extended. Lay it on the table nd let it sit for a minute or two without touching it. I'm interested to see how many DB's your loosing if any. Good luck sir
[AT&T Samsung Galaxy S II SGH-I777] shinshoryuken:
I did that the first time..and it did show lower signal performance.
[AT&T Samsung Galaxy S II SGH-I777] gr8hairy1:
Very odd. Well I guess not too odd. A thicker battery by definition would be able to block more signals. Thanks for the update.

They have these back in stock on Amazon, bought One today
[AT&T Samsung Galaxy S II SGH-I777] joeybear23:
Depends on the placement of the modem...

Is it behind the battery?
[AT&T Samsung Galaxy S II SGH-I777] ElectronicYank:
this is what i got on my first use from 100% to 10%, i can easily say this is the best 13 bucks ever
[AT&T Samsung Galaxy S II SGH-I777] wgarrido:
Get a NFC app from the market and use your credit card that has paypass. Worked for me with UnNamed. I don't have an extended battery to test with though, but you can try it.
[AT&T Samsung Galaxy S II SGH-I777] Jadefalkon:
My battery came yesterday, now I'm waiting for the TPU case. How long has the battery been lasting for everyone?

I've been using this battery for a week or so with CM7. Great bang for the Buck in my opinion. Cover isn't perfect but with the mtt case it's fine.
[AT&T Samsung Galaxy S II SGH-I777] sdas683:
I've had mine since I started the post (about 2 months) and I'm still getting great battery life.. unplugged about 5 am its now 1245 and I've been browsing/using about 4 out of those hours
[AT&T Samsung Galaxy S II SGH-I777] churraman:
I ordered the GTMax 3500 mah battery on amazon last saturday and it was shipped today. I get through the day with the stock battery with GPS, WIFI, HSPA on and I unplug at 6am and get home at 7-8pm and when I get home I usually have between 20-40% left. I ordered this battery not for everyday use but for the days I am on call for 24 hours or more, since plugging to a wall charger is a bit hard to do some of those days. I'll post back about results when I get the battery.
[AT&T Samsung Galaxy S II SGH-I777] Jadefalkon:
Wow, I hope I get those kind of numbers with it. I just rooted and flashed Unnamed over the weekend. Ill try the battery in a few days after I'm sure everything is OK.
[AT&T Samsung Galaxy S II SGH-I777] Alucardis666:
Such a great deal. Thanks again
[AT&T Samsung Galaxy S II SGH-I777] churraman:
I rceived my battery a few weeks ago and Im loving it so far. Im able to get up to 48 hours with a single charge. One thing I noticed is that the phone tends to slip more easily out of your hands due to the slick replacement cover. For this reason I bought a bumper case from ebay for 8.99 and now it is perfect.

http://www.ebay.com/itm/Orange-Blac...Accessories&hash=item56474e44ec#ht_2543wt_962

Ill post pics as soon as possible.
[AT&T Samsung Galaxy S II SGH-I777] mj0528:
Any updates?

Thanks
[AT&T Samsung Galaxy S II SGH-I777] skatin707:
Thanks for the link to the bumper! My i777 will be here this weekend, I'm going to get me the extended battery and that bumper :D

Any updates on how the battery is working? I'll be ordering mine from Amazon, where did you get yours?
[AT&T Samsung Galaxy S II SGH-I777] churraman:
Here are some pics of the phone with the extended battery and the bumper case from ebay. Sorry for the quality of the pics, they were taken with an htc hero:D.

It looks really good in person and the bumper really adds some welcomed grip with minimal bulk. Overall the phone feels good to hold with one hand and it offers some protection to the corners in the event of a fall. The case and the battery cover are almost perfectly flush. As for battery life I'm getting between 36-48 hours depending on the use. Keep in mind that I only use this battery when I'm on call and /or know I'll be more than 1 day without being able to charge because otherwise the stock battery lasts me through a normal day. That being said I'm gonna try t out during a normal day to see how long it goes, heck I may even like it so much that I may ditch the stock batt:D!!!

Edit: I bought it from ebay from the link posted in the OP!!
[AT&T Samsung Galaxy S II SGH-I777] skatin707:
The link was to the case, where did you get the battery?
[AT&T Samsung Galaxy S II SGH-I777] mj0528:
Just got it, back case fits way better than ebay one
[AT&T Samsung Galaxy S II SGH-I777] mondjei23:
Help please!!!

I received this battery today Gtmax extended battery 3500mah for sgsii but i have a problem, i cannot charge the battery directly from my samsung galaxy s ii (at&t version), it keeps on restarting and not even charging (boot loop) of what they call it i guess.Please can someone give me a solution. Thank you...
[AT&T Samsung Galaxy S II SGH-I777] shadow65781:
I just ordered one also, your the first post on here saying it bootloops. Send it back, I don't think there's a fix. I'll post my experience when I get it.
[AT&T Samsung Galaxy S II SGH-I777] sdas683:
Hmm..

Well, I have had the battery since October with absolutely no problems whatsoever.

Charged with phone off

Charged with phone on

Flashed with THIS battery in

I agree with shadow65781 here, you are the first of many to be experiencing this issue.. I see you also only have 1 post, not to assume anything but have you flashed a different firmware? Possibly incorrectly? I've flashed every current ROM released since December with no problem, also have charged via USB on a computer, USB on my car stereo, USB through cigarette lighter, and the usual wall outlet ALL with the phone on/off doesn't matter.

I would suggest going back to stock with ODIN and give it a shot again if you have indeed tried to change anything. Let me know if you need help.. :confused:
[AT&T Samsung Galaxy S II SGH-I777] rusto:
Nice touch with the sticker...gave me some ideas.

Thanks for posting this...I'm looking into what are the possibilities to protect the phone while having one of this type of batteries.

I really want to see what others have done to protect/spice up their phones.
[AT&T Samsung Galaxy S II SGH-I777] shadow65781:
Received my battery today,

The back wouldn't snap on at the top right as your looking at the back there's some kind of protruding leg thingy about where the sim card is,clipped it off and fits much better. Almost perfect. No bootloops yet.
[AT&T Samsung Galaxy S II SGH-I777] nixonpjoshua:
I bought this battery and it was awesome... For about three months, just now I started to have boot loop issues on the last week and now I can't even get it to charge enough to turn on:-(
[AT&T Samsung Galaxy S II SGH-I777] trazer_se:
Just received a couple of these from an Amazon seller and neither battery works correctly. Will not charge at all when the phone is off and if it is on and you connect the charger it turns the phone off.

I purchased two of them and they both do the same thing, and I tried them in three separate SGS 2s.

Sigh, my search continues.
[AT&T Samsung Galaxy S II SGH-I777] lunercrab:
I actually just got this battery a few days ago. I haven't had any issues. I'm on my second cycle charge as we speak. Its been lasting a long time so far. Who knows how long it'll last though but for 15 bucks it was worth it IMO
[AT&T Samsung Galaxy S II SGH-I777] MaxRabbit:
Looks like the perfect cheap backup!
[AT&T Samsung Galaxy S II SGH-I777] RubbberDucky:
I just ordered this battery a couple of days ago and was informed of this thread on it. After reading through, it seems there is only one guy getting bootloops and he may be in the wrong forum or something, and one other that is having some issues after a number of months using it.

Anyone else had this battery a while that has a longevity performance report?
[AT&T Samsung Galaxy S II SGH-I777] shadow65781:
I've been using it for about a month. No problems with the battery whatsoever.

I did have to nip off a little plastic tab like thing that sits over the sim card location on the replacement back cover because the top right corner of the cover would not seat.

It seats now with the tiniest of gap at that corner, but doesn't feel solidly seated, like it could come loose.

So I bought case made for this ext battery and back, it's mentioned somewhere in this thread, get it from amazon if you can, took 3 weeks and several emails to get it from a sight also listed in this thread (amazon was out of stock I think they have them now.

All told about a 25 dollar investment.

For me it's been a great deal so far.

I highly recommend both the battery and case.

[AT&T Samsung Galaxy S II SGH-I777] shadow65781:
Odd, the only difference that I could see between them was one came with a lanyard, that's the one I bought and one comes with a little bag,

Get the one in the op.

I just order this battery using the OP Amazon link, but I'm also going to order this battery cover (link below) as the little kick stand could be useful. I don't see why it would not work unless this is a super thick battery. Will report how it goes next week when when I get everything.

Get them baby seals. Does anybody have the link to the intellicom battery with the matte black cover?
[AT&T Samsung Galaxy S II SGH-I777] nappent:
I got mine which was using the link from the OP and the battery cover is crap. One of the lower clips broke and the top corner to the camera sticks up slight even when everything is snapped in (minus the broken lower clip/hanger). So far I'm not too impressed but it was only $15 with shipping so the quality is what I'm paying for. I just hope I never have to take the rear cover off as I'm sure more clips/hanger will likely break.
[AT&T Samsung Galaxy S II SGH-I777] dli7319:
well mine fits perfectly so i think i got a different back, its not curved at the top; i bought it newegg

i also got the bumper from churraman's link and they all fit perfectly

the only thing i want now is for att not to throttle my unlimited plan after 3 GiB
[AT&T Samsung Galaxy S II SGH-I777] stickbo:
Ordered the battery and cover from the op and all i can say is damn. This is how the phone should come stock. What a huge difference. No bootloops or any other issues. The cover fits tight as hell . More than happy. Its 15 bucks so i wasn't really worried anyway.

Price drop to $10.99, just hit the "w/e just try it" price mark. I'll post back with my results. Also ordered an SGP Neo Hybrid EX, let's see how this comes together - will hopefully be just what I need for some upcoming long ass flights.
[AT&T Samsung Galaxy S II SGH-I777] nappent:
that's a different seller but oddly Amazon is grouping the reviews together. All I know is I order my from "BlueMall".

Go figures... I order my SGS2 for $9.99 and then it drops to a $0.01 a day later. I order this battery/cover and then there is a price drop a week later.
[AT&T Samsung Galaxy S II SGH-I777] MaxRabbit:
Yeah, and that other phone I bought last year for $500 is now worth $50; stupid technology! ;)
[AT&T Samsung Galaxy S II SGH-I777] nappent:
A year difference is one thing but I'm talking about a few days later... Not to start anything.

Anyway, looks like the prices for this battery is down even more. $7.03 at http://www.amazon.com/gp/offer-listing/B005Q75A84/ref=dp_olp_new?ie=UTF8&condition=new

[AT&T Samsung Galaxy S II SGH-I777] nappent:
That battery cover didn't work... It wasn't tall enough at the very bottom. I try to shave the inside of the case to make more room but it just never worked. So don't buy that cover as this GTMax battery is too tall for that case. Oh well. Would love to have a kick stand one day.

Ok I have been using this for over a week and I regret to inform you all that this doesn't get any better battery life then the stock battery

Just over 16 hours with 3h 11m screen on time
[AT&T Samsung Galaxy S II SGH-I777] crystalstylez:
others seem to get better than that though. If you have an exchange account on push or brightness way up; these could be factors in your time.

I got the battery, and thankfully the back fits close to perfect and it's not going anywhere its on nice and secure.. Thanks OP... Charging now mine arrived at 60% will charge to max and let it drain to 10% curious how much life I will get.
[AT&T Samsung Galaxy S II SGH-I777] IVIadness:
I am testing today, so far looking more like a backup battery than an extended will know more at the end of day.
[AT&T Samsung Galaxy S II SGH-I777] nappent:
What's your setup? Rom/kernel?

I'm on..

Rom: SHOstock 1.9.4

Kernel: Siyah 2.6.14

OC: 1400

Gov: ondemand

I/O Scheduler: sio

Also I have removed all most every safe to remove app based of this spreadsheet: https://spreadsheets.google.com/spr...1gdDJRekl4QmkyNmIzUmRvX2h3UDVkQXc&output=html. Boot time is about 5-10 seconds faster by doing this.

Also to note, from my experience, it takes about 1-2 weeks for the phone to fully calibrate for the new battery. I'm sure it would be faster the more you use your phone. Attached is my first full 100% charge down to 1%. So it should only improve from here... in theory that is. Unless the quality of the battery is very poor... which I would not be surprised with based on the cost of the battery.
[AT&T Samsung Galaxy S II SGH-I777] IVIadness:
I am rocking serendipity and latest entropy, also doing on demand gov myself.. I just wanted to report still at 70% with almost 3+ hours of screen time and countless web surfing and streaming Pandora.

My update: I am thrilled with this battery! Makes it through some long Army training days!
[AT&T Samsung Galaxy S II SGH-I777] IVIadness:
Yeah this battery rocks, 51% left and a screen time of 4 hour plus, and about 2 hours of Pandora, and hour of gaming, and and hour of talk time.. And 15 hours off the charger.. I plan on only using it on trips so it's perfect for those long days away from plugs. My average daily screen time is about an hour just wanted to push it hard.
[AT&T Samsung Galaxy S II SGH-I777] nyydynasty:
i just ordered one of these as well. I'm hoping its as good as everyone claims. I just added "Good For Enterprise" on my phone to get company emails but it kills my battery at about 3-5% an hour (just that app alone) - lol

[AT&T Samsung Galaxy S II SGH-I777] sdas683:
I don't understand this confusion on where to purchase battery, the AMAZON ID # is in OP and hyperlink is post #2.. Where is all this newegg and other products coming from? If you ordered something other than whats in the OP then stop wondering why A) your sh1t doesnt fit or B) why don't you get the same results! If you only give a new battery a day to perform I'm willing to bet you'll be disappointed most of the time.
[AT&T Samsung Galaxy S II SGH-I777] JohnnyKushi:
This is the battery I've been using for the past two months and I get up to 8 hours of screen on with it before I need more power and I've gone up to 20 hours between changes.
[AT&T Samsung Galaxy S II SGH-I777] shraf2k:
i actually ordered it from the amazon link in the OP's post... i filed a complaint with amazon.
[AT&T Samsung Galaxy S II SGH-I777] JohnnyKushi:
If it hasn't shipped you can just cancel your amazon order. The link in the OP is to the one with the thicker back plate but it's also a little cheaper then the revised one which can be found here.

Because he said earlier, his case doesn't fit.
[AT&T Samsung Galaxy S II SGH-I777] shraf2k:
and my phone doesnt boot up... theres something to complain about...
[AT&T Samsung Galaxy S II SGH-I777] evohmonkie:
Order same battery as in op. So far it has been great. First charge lasted 28 hours with almost 5 hours screen on time. Used for phone, data, for gps and wifi hot spot for several hours too. Back sticks out quite a but definitely manageable. I would say the size to battery life trade off is fair and definitely worth it for only 10$.
[AT&T Samsung Galaxy S II SGH-I777] nyydynasty:
got mine in the mail today. Everything fits perfectly. Didnt come with the lanyard but I wouild have thrown it out anyway. No complaints here. The battery cover fits perfect and I can't complain about thickness. It's definitely thicker, as expected, but its not as bad as I thought it was going to be.
[AT&T Samsung Galaxy S II SGH-I777] Masamushia:
Halp.

Been using mine for 3 days, charged to 100% and let it drain until the phone shut itself off, then charged it to 100% again and turned it on. I'm getting the same exact battery life as the stock battery, and it's quite depressing seeing as the results that others have got are quite fantastic. If I had wanted a backup battery I would just complain to AT&T and get one for free, like I always do. To clarify, I bought the one from the OP, the case fits perfectly, it didn't come with the little strap. Not sure if I should give it a few more days or if I should file a complaint for a defective product.
[AT&T Samsung Galaxy S II SGH-I777] JohnnyKushi:
Although I'm not an expert I don't think Deep discharging your battery is recommended to maintain a lithium ion battery.

batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries

Also I'm sorry shraf2k I missed your post actually stating your problem. I was actually under the impression you had JUST ordered it when you posted.
[AT&T Samsung Galaxy S II SGH-I777] dream5hift:
Surprisingly got the battery Saturday instead of next Wednesday as said Amazon. Putting the case caused me some trouble but I just had to put some force to snap in all tabs. The phone is heavier but feels nice in hand because I have long hands.
[AT&T Samsung Galaxy S II SGH-I777] nyydynasty:
I thought it was just me. I'm not noticing ANY additional battery life...not even in the slightest. And without NFC, I'll probably just go back to stock, now that NFC is starting to come around for our phones.

Here's my results after first full charge. Voice call was 2hr 7m 22s.
[AT&T Samsung Galaxy S II SGH-I777] Masamushia:
Nope. :/ I've been giving this battery some heavy use, so there's no reason it shouldn't be properly calibrated by now. Think I'm just going to return the product and ask for a new one.
