2000mah Battery Options for AT&T Galaxy SII

[yurkinator]

Same size.

Pretty sure it's the same size as stock, but will know further once it arrives. If yurkinator's around he could answer definitively.

Did you get yours yet, if so how do you like it? Mine was supposed be delivered by today but I had to leave for a trip this morning, so it'll pry come in later today. Was hoping to swap it out as at the airport and two quick calls and a few text and I'm already at 80%... ughh lol

Oh yeah, sorry. I did get it. Took a little longer than expected, seeing how they processed AND shipped the same day I ordered.

Still, it fits perfectly. Actually, mine seems to fit better than the original and I can tell a huge difference in the overall life. On the first charge I was able to go nearly two days before having to charge it at %4! While I didn't use it as much as previously during that time frame, it was still very impressive - I hadn't been able to go that long since the first week of owning this back in 2011 on GB.

I'll upload a screenshot of where I am right now, but I can tell you there's noticeable difference for me over the original two year-old OEM. This was a great find at the price, so thank you again!

Edit for picture.

Sweet. What I don't get is how you can buy knock off batteries for everything from these phones, to laptops (win based), and whatever else and they work no problem. Yet you buy an knock off battery for any Apple product it's f'd and never works right, need a new battery for my Macbook Pro and nothing but complains and issues with replacements unless straight from rape you in the butt $$$ Apple, people that did the same for the iPhone, Pods etc themselves same issues. Fricken Apple lol

One more picture, about to charge now. Again, while some may not think these stats aren't that big of a deal, it's a HUGE improvement from the old stock battery!

meh..hasn't been my experience, its been off the charger for an hour and i'm already down to 93% ...probably sent 5 texts in the past 1 hour and that's about it

paid an online bill and im down to 89% lol...

 

[SteveMurphy]

Really? Sorry to hear that; it's not going to get you 2+ days of usage but I've not had that bad a drop off. Could be your kernel. May I suggest AJK with one of the built-in profiles? That's what I'm on and have found the battery lasts about what the original one did the first day I had this phone.

I can say mines been awesome. Calls, text, just over 2 hours on screen time, nav gps for about 30 min, downloading etc.. and still had plenty left at end of day, over 20%, stock battery couldn't do that w/o dying last few months and not even two years old. Would of posted a shot but plugged it in and threw stats off. Stand by seems to be the norm for me on sho3, about 1% ever hour and half (wifi set to only stay on in sleep when plugged in, makes a big difference with Androids wonky wifi searching).

So far love this thing, can't beat it for 5 bucks. I've been browsing for like 50 min and phones been off the charger for 1 hour 57 min and only dropped 13% and that was with two tabs sometimes.

Sounds like you have more of a kernal/rom/app issue, something is draining to cause that difference with only a few text.

Yeah,problem is around the same time that i changed the battery i also switched to straight talk (from ATT) and I feel like its constantly searching for a better signal and also around the same time i updated to latest version of Task's ROM...hard to tell whats the problem source lol

mind telling me what profile do you use with AJK? thanks

The ST observation is interesting; I've never paid any attention to that, so I can't say if I had the same thing with AT&T. Anyway, I mainly use either Battery or Topiratiko's profile, mostly because Im too lazy to create my own and they've worked great for me.

Both of the screen shots I uploaded earlier were on Topiratiko's, which is a pretty powerful profile for our phones. Both he and AJ have done a great job tweaking it, and lately it's all I've been using.

Seems to be getting better and better as I use it more, guess breaking it in and charge cycles. I'm very impressed for $5, is it actually 2200mah, not sure, I thought when you got to 2000+ the batteries were larger and wouldn't fit from what others said and from what I saw first hand, and if you compare the stock and this one it's slightly different and is a tighter fit. Maybe it's like 1800-2000... who knows lol. Either way it seems slightly better then the stock battery for me so far and seems to be getting better as we go. I only run Shostock3. I calibrated it.

I noticed one thing, with this battery it doesn't seem to play well with my dock. But then again I think the dock I have now is "faulty" vs the same one I had before that had no issues. So not sure if it's the battery or dock, but its extremely slow to charge, and if using Nav, or streaming music etc, it won't maintain a charge (whereas my old dock, which was the same as the one I have now, I could be doing internet, streaming music, nav, text etc and maintain 100% through a trip). I'll have to see with a car charger, as I do think this dock is messed up.

edit - yeh must be the dock, I just had it plugged into my computer and it charged like normal on usb.

 

[surf1]

Ok more I've used this battery, here's the deal, it works great for normal use. However Whether car dock, car charger, or usb charger, or even the wall charger... it won't continue to charge (let alone hold the charge) like the stock battery does. Talked to a few other owners of this battery and samething. Not sure what causes that. My car dock is screwy right now but the same one I had before the stock battery would charge up to 100% or maintain 100% if plugged in like that even if running GPS/Nav, streaming music, and getting text or emails etc. Same for the car charger or wall charger. The 2000mah battery even if plugged in to my wall charger and browsing will discharge, but a bit more slowly then if not plugged in.

So if your going on long trips or anything and really needing Nav or just a heavy user of your phone plugged in, your best off buying a real Samsung replacement. Otherwise for just normal use it kicks ass for 4 bucks.

That's weird, because I've left it charging over night and it gets all the way to %100 and maintains it, exactly like the original. I agree with yurkinator that this is in no way a true 2200, but to me it's operating exactly like my old battery did on day one.

Maybe I just got a lucky battery!

No it charges to 100% if you leave it, no problem there. What I was saying was if it's charging like on the car charger and your using Nav, or even if hooked to the wall charger and like browsing or whatever, the charge will drop while in use. With the stock Samsung battery it would maintain 100% or if it was used and I plugged it into the car it would charge back to 100% even with Nav running, streaming music, emails etc.

Think I made a mistake in my op, I meant while the phone was in use. It'll charge on my dock or car charger. But even if I stream music, it'll drain almost as if not plugged in, just not as quick as it would if the phone wasn't hooked up.

Oh, Ok, I get it now :screwy:.

I'll test mine out tomorrow and see if the same thing happens, because I've not tried that yet.

Seems to be the screen, I just streamed music earlier with screen off and it slowly was charging (not as fast as the stock battery in the dock), but with it on it seems it draws more current from the battery then it's grabbing from the charging cord whether wall or car. The other night I was browsing and it was dropping % while plugged into the wall. So for whatever reason the battery can't make up for the draw being placed on it with like Nav etc in use and screen on even if plugged in. Odd... not sure what would cause that. The stock battery had no problem charging to 100% or maintaining 100% in the dock or car charger even if using Nav, streaming etc

But yeh besides that, if using like normal through the day, browsing, calls, gps, text whatever... it seems to last as long as the stock battery if not longer. When I'm browsing I can go about 20% per hour which gives me at least 4 hours on screen time and still plenty left, which was the best I got with this rom tweaked on ajk and battery profiles back when. I just keep it as is with whatever jeboo kernal is set at. So I still think the battery is an awesome replacement for the $

I spent the $5 to get this battery to see if it was an improvement to my stock. I used it for about a week and decided that I was getting better performance our of my stock battery. Granted my stock battery is just under 1 year old and still gives me around 4hrs screen time with Slim Bean and AJK.

Not bad as a back-up though.

 

[SteveMurphy]

Well, this battery may not be the best thing around, but my old stock is 2 years old, so the Attain has been a noticeable improvement for me.
