GTMax 3500mAh High Capacity Battery + New Back Cover $12.99! - AT&T Samsung Galaxy S II SGH-I777

So I found this battery on Amazon about a week ago for $12.99.. Ordered it and I am extremely impressed. Running Stock Rom + Root, constant use daily.I was really getting pissed off with the battery that came with the phone, it just doesn't do it justice.
Pro's - Been using the phone (50% Brightness, Downloading videos, youtubing, texting, phone calls, tinkering with GO Launcher stuff, almost played through a whole game of Words with Friends) Came off the charger at 3 P.M. today, legit screen on using the phone action about 4-5 hours tonight and it's now 11:25 P.M., battery is just hitting 65%! Extremely impressed with the performance of this battery and would recommend it to anyone that needs some extra juice.
Cons - It makes the phone about twice as thick towards the bottom half (I actually like this, it makes it much easier to hold on to and just grip in general). Also adds a significant amount of weight to the phone but nothing annoying, just saying.
UNSURE - Not sure about the NFC Capabilities of the battery, no one around me here has a phone with NFC so I can't test it... Honestly for the performance I could give a S*** less about NFC whether I keep it or lose it.

Awesome price! Great buy for trip battery.
Sadly with that thickness, I would rather club baby seals
Nice find, going to have to think about this buy some more.

so are you able to charge normally? or is it like the other batteries where it throws you into a boot loop?

Just got an extended battery myself. Yeah it's thicker but using a phone all day without worrying about charging it, worth it for me.

Yeah, I just ordered this one too.
I had one on my captivate and I really liked it.
What does it matter if your phone is thin but you keep getting warnings that you need to charge it?
On my captivate if I got down to half of the battery with the larger battery I didn't have to worry, I had good 8 hours of use left.

Just confirmed it does NOT have this boot-loop issue common with the aftermarket batteries. Operates the exact same as the stock battery, still unsure of the NFC capabilities.

just received mine yesterday over 20 hours still 65 percent battery remaining. Will post a screenshot when the battery gets to 10 percent.
Sent from my SGH-I777 using xda premium

Sorry, but I think GTmax stuff is not that good, I purchased 3 batteries made by GTmax, there is no description of mA with just some generic label. Also, out of the 3, 2 were junk lasting only about 10hours with minimal use. Only one battery was decent, pretty close to OEM.
Also, looking at the battery debug info *#*#INFO#*#*, these batteries are more volatile than OEM, as the amps and temperture fluctuate more than normal.

Good Battery Possible Bad Cover?
I turned my phone off to put this new battery in. I fully charged it before turning it on.
It lasted 42 Hours before it died.
I was running Bluetooth, Pandora and Wifi Medium-Heavy Duty.
So the battery seems good, But it seems the back cover wasn't crafted all that well UNLESS I just got a bad one. It seems like a corner of it won't stay pressed down. Its not a huge gap, but it is somewhat noticeable.
Is anyone else think that their back cover doesn't fit all that well or is it just me?

Can someone post some pics of this on your phone?
The pics on Amazon don't show it on the phone and don't show a side-view of the new back cover.
...nevermind, pics in first few posts. company blocked the images

Got mine earlier today I will post back if there are any issues.

Extended High Capacity 2300mah Phone Battery - Anyone have try this?

Hi,
Found this link and its kinda cheap compared to Seido. Anyone have tried this before and any review?
http://www.usbfever.com/index_eproduct_view.php?products_id=1173
I bought this battery from amazon
http://www.amazon.com/gp/product/B001PRCU0U/ref=ox_ya_os_product
It was $23 shipped. Very good battery its best to run it down then recharge it. I can leave gps/3g on all day and not fear a dead battery after a few hours!
Pretty decent battery and half the price of the Seido. I've been using it for a few months now. The only problem is the back cover only ships in one color (black). Otherwise I would recommend it.

wow. it is the same product at the amazon. now we got cheaper price. thanks for the head up!
Still waiting on mine from china. 10-21 Days, that is crazy.
What I really wonder regarding all those extended batteries:
Why do the manufacturers leave so much space unused? I mean if you get the new back cover, it must be as thick as the battery. But on top and below the battery there is just air floating around between the phone electronics and the extended cover, where battery power could be placed.
I would be glad to see a manufacturer use this space as well - so the battery might be formed somehow like a flat T. Would be a little more complicated to produce but might well be worth an extra 1000 mAh without making the phone thicker - that should convince some customers I guess.

[Q] How much thicker is the extended case?

Hi,
I'm getting my Pro2 today and since I'm very worried about battery life (I hope to be using the TP2 A LOT), I was wondering how much an extended case adds to the phone.
This is what I had in mind (German Ebay but I think you know what I mean from the picture there):
http://cgi.ebay.de/Power-Akku-Li-Io...4579?pt=DE_PDA_Zubehör_KM&hash=item53e279e3e3
Does anybody have such a case for an extended battery? How comfortably can you carry the phone in your back pocket compared to the normal case?
Thanks in advance!
I don't know if I would bother with a case like that (it looks like it'll make the phone about 50% thicker). With the stock battery, it lasts more than long enough for me to get through the day, so all I have to do is plug it in each night. What I'd do is just see how long it lasts you for the first week or so then decide if you want to get an extended battery, HTC makes an extended battery and cover so I'd look into that rather than a third party one.

If you think the phone is fat now, don't try it. It makes it bulkier but also a bit uglier (and i have yet to see a silicon type 2-piece case for the extended back cover (how are you going to protect it after install the extended stuff?))
Wait and see if the normal battery suits you , then if yes just go out and buy another one plus battery charger from ebay and you are set! If not, well it doesn't really give you a choice. You are going for the extended.

After all the purchases i have inside ebay and seeing the prices of the original models, i'd be nuts to prefer the official against the oem from a seller with proven history!
Thanks for your replies!
The extended case does indeed look ugly, so I'm holding off buying one for now. However, despite my light use so far (I need to get the data connections turned off first), it does feel like the battery doesn't last long at all, especially compared to my good old K750i, which I could use to play mp3s for literally days (which I wasn't expecting with the TP2, of course, but still - that was really nice).
I'll wait and see, I guess. But since the docking station, which I also got from ebay, doesn't seem to recharge the battery fast enough, I might have to look for a solution soon.
I have also seen a 1750 mah battery that isn't bigger at all. It fits underneath your existing case, and it is an improvement of 250mah.
I cannot post links atm. Just google "Seidio Inno 1750mAh Extended Life Battery " and find it on amazon. It costs about 50 dollars.

Hmm, $50 is a little too much for my taste, since I paid only little more that $100 for the whole phone and there are plenty of batteries for less than $20 out there.
I have the extened back and battery. Well worth it if you use the phone alog like I do. with the OE battery I was getting down to less than 20% battery life in not time at all. Now I get down to around 50% by days end.
Google HTC and 74H01486-01M (the part number for the OEM HTC extended back) they cost $12.95 (USD)
When I set the extened back next to the phone with the OEM back on it, the extened back is as tall as the original phone, so it is adding about 1/2 inch to the thickness.
Don't expect to find a case for it either, I have had my phone for 1 year and have yet to find a case that it fits in. I have an old worn out one that was stretched that I can get it into.
@wooptyone: Thanks for sharing! I am back to considering the extended case as well since I will be reading a lot of ebooks with the TP2 and the battery does indeed go down pretty quickly. Also, I discovered that I'm not using a case anyway since I have the phone in my chest pocket all the time. The only downside is the docking station that I bought for it, but since that isn't working as intended (apparently the current isn't enough to load the phone while also acting as a USB port ), the extended case so look attractive right now.
Sadly though I can't find the case you mentioned in Europe and S/H would double the price.

Where is the magical Samsung NFC Battery?

I don't remember where I saw it, but I remember there being a Samsung Galaxy S II 2000 mAH battery that was NFC-Capable and required no bigger battery door.
Does anyone have the link?
Search ebay for this: GENUINE-SAMSUNG-GALAXY-S2-i9100-ORIGINAL-BATTERY-2000mAh-HIGH-CAPACITY-COVER
I am new to this forum so I can't post a link yet.
I purchased it a few weeks ago for my At&t S2. It works great! When at home on the weekends my battery only goes down to about 70% by the end of the day, before it usually dropped to around 30-40%. Although the battery fits perfect the new cover was made to fit only the Korean version of the phone. I used an xacto knife and trimmed the interfering catches on the sides of the new cover so it fit in place. The end catches of the cover still fit. I then placed the phone in a TPU case which fit perfect without any budges or stretches. Actually feels better to handle and still weighs 8 grams less than my old iPhone 4.

Looking at the pictures it seems that the new battery cover is every so slightly larger. Is that true?
Yes, the Korean battery cover makes the back of the phone flat instead of dipped at the bottom. Also recesses the camera window slightly which is good to protect it. Same texture on the new cover as the original one. It's too bad Samsung didn't make the catches the same on both covers.
The battery works w/o reboots when charging via USB?
So, does it say "Near Field Communication" on the back of the battery like the original 1650maH one?
I have an extra 2000 mAH NFC battery for sale. PM me.
The Korean 2000ma battery does say NFC on the back and I have not noticed any reboots when connected to my PC. I actually don't connect via USB very much, just use Kies air which works good.

Would you say that the back would have no problem staying on if you didn't use a case? I have the car dock and a case won't fit, but I think the battery would. Thanks.
I have not tried to carry the phone without the external case. Mine won't fall off but doesn't require much effort to pop it off with a finger nail. I would be uneasy to use the Korean back without the external case. I did have to give up my home charger base because of using the external TPU case, but I felt it was justified by the extra protection provided by the case.
I have a Ballistic SG case on my phone. Would this battery possibly still fit?

I searched and all I'm finding are international sellers, which takes forever and in the past I've gotten several fakes from international sellers. Anyone know if Amazon or a US Seller has this extended ORIGINAL battery?
Thanks!
I am also hesitant to buy the battery from a foreign 3rd party seller. I spent about an hour and a half on Samsung Korea's website with google translate and I haven't been able to find it for sale on their site.

I MAY be going to Seoul in the next couple weeks... if I do end up going I'm def going to pick one of these up
So I got the Battery today, the battery cover doesn't fit perfectly. I had to get a buffer and do it to both sides of the insertion cover (left + right) for it to be "snugly", though I went overboard on the right side and it's pretty ugly if you look in between the cracks.

Sounds far less than ideal. :-(
The less than perfect fit on the battery cover was not an issue for me. I knew of the issue before ordering the battery. What was important was extended battery life and I wanted to put the phone in a light weight case anyway. The TPU case was a perfect fit and affords a better grip then no case. I am running JuiceDefender in auto mode with a very stock AT&T phone. Bluetooth and wifi are always on and two imap email accounts. On work days I'm usually down to around 70% by night, weekends typically 80% left. I use the phone only on a moderate level, no game playing or videos. Just nice to know I have plenty of reserve left just in case I need a heavy use for a few hours.

Juice defender is so crippling. If you're only using 20-30% all day with JD enabled, why bother? Might as well unleash your phone's full potential, and let it do it's thing. You may only have 20-30% remaining at the end of the day, but as a non-power user, why do you bother using JD? Are you OCD like me and hate seeing less than 75% battery remaining? LOL
It fits perfect now, and it's still thinner and lighter than the original Galaxy S (Captivate)!
Any pics? I want to get an idea of how much thicker it gets.

Ive Read About Laza's Regular 1900 Slim Battery's But This One Is Different And Looks Better Than Other Extended Battery's Ive Seen. Plus All Of Its Reviews Are A1
I just bought this battery on ebay today for $13 and its an USA seller too. It should be here a little less than a week. Ill probably put up a video or pics of my first impression and close up the battery if you guys want. Then a little after I'll do a full review once I train my battery and give it some tests. I'm a pretty heavy user so dont be disappointed if I get less than 10 hours, since I average 3-4 hours off the stock battery.

I would suggest you read the reviews right from the Amazon link you posted. They give you exactly what you are asking for, personal reviews. Because of this I ordered one and I love it. I cut a hole in my TPU case to fit the cover, it's not perfect it gets the job done as I don't want my phone to be without a case/cover and it only cost me 4 bucks at the time.
When you get it it says that it needs five full charge and discharge cycles for full capacity. I actually used it once for TWO DAYS on a single full charge. :highfive:
The oddly shaped case is a love or hate design. The plus is that the edges are the thickness of a regular case instead of the fat thickness all other extended batteries have. I also feel it fits better and the buttons, power volume up and down, work better than other backs I've seen although I've never seen the Seidio back. Minus is that the design has this huge unsightly bulge and less than nice aesthetics.

This battery is great idk why one of the posters thinks they lie. I bought if for about 13 bucks. I can ge about 14 hours of medium to heavy use. Which is way way better than stock. I have a sorta review on the android forums i just cant link cause im new here :/

Seidio Innocell Plus Battery Case

I just bought this case off of Amazon and stuck it on my AT&T One X+. I bought the last "used" one for only $25, but as far as I can tell, it's in brand new condition which is awesome. It fits the phone perfectly, though it's definitely chunky, but less so though than I though it would be. And I gotta say, I'm liking the heftier feel to the phone. The shell is really smooth and feels great in the hand. The main reason I went for this case over a few others was that it actually makes use of the pogo pins on the back of the phone, so there isn't a stupid USB cable sticking out of the side like this case. The battery in the case is hot swappable, so you can put in any similar sized battery to charge your phone if the one inside dies. It's the best of both worlds when it comes to a phone! :fingers-crossed: The battery that comes with it is rated at 1750 maH, which is almost 75% of the capacity of the internal battery, so it has added many hours of battery life to my phone in day to day use. I'm still gonna need a couple more days to test it out, but if anyone has any questions about the case, let me know. :good:
it does look great but the review are kind of bad...
if you could post your impression like after a month of use it would be great!
besides that..what you think about the protection of this case does it have big lips that you can put your phone on the table with the screen faced down?
