What is the difference between the batteries in our phone and the 9003 ? Mugen has a 1600 listed for our phones.
Let us know if it fits . Thanks .

Oh sweet man please let me know how it goes. I am either going to do that or get the nice big fat one with the stand

I just bought a generic 3500MAH battery for the Vibrant off Amazon for $15. No regrets so far.

You can get the Momax 1700mah battery for $17 from ioomobile or $19 from ebay. Both with free shipping
I use an original vibrant battery in my i9000 too so the momax will fit the vibrant/i9003.

Please, tell me how are your results. I want to have a battery with more capacity but using the same back case.

Just waiting on its arrival now. I looked into other brands, but kept finding massive amounts of negative reviews, like the Momax battery.
Like from this thread: http://forum.xda-developers.com/showthread.php?t=478270

I actually had the Touch HD version, which worked perfectly fine for me Which was why I had no issue buying it for the i9000. I have been getting around 40 hours from light/minimal usage on the MIUI.us rom. I am getting around 30-35 hours on the standard i9000 and vibrant batteries.
I also bought one of the cheap 3000mah ebay batteries but didn't have any luck with that. I was getting around 45-50 hours but after a few recharges it dropped to less than the original battery.
I firmly believe in "you get what you pay for" however I have to say I have not had any problems with the momax battery so far, touch wood.

Was it delivered? My battery is worse every day even with Bi-Winning v3 with Bullet kernel. It dies too quick! Using WCDMA with HSDPA is the same as seeing my battery % going down realtime.

There are a couple things you can do to stretch battery life without too much compromise.
First, go with a black background. There's a free app on the market that's easy to miss. Do a search for blackwallpaper, all one word. AMOLED screens love darker colors when it comes to battery usage.
Second, get a 2g/3g toggle and switch to 2g when you don't need data and are primarily just texting or playing games.
Pick up the Bali-X kernel. Lots of battery saving goodies in there. Afterward, pick up SetCPU and reduce the voltages as far as you can without getting crashes or "sleep of death" issues.
Now, even when gaming, my battery isn't too stressed, and when I left it off the charger overnight, after 9hrs it had burned through a miserly 4% battery.
Finally, get a retractable usb data/charging cable. Can be had for a penny plus a couple bucks shipping. Retractable means easily pocketable, so whenever it occurs to you, break it out and connect your phone into whatever PS3, TV, Computer, or Laptop is available that has a USB slot.
The battery hasn't arrived yet. Supposedly takes as much as two weeks. I'm waiting with baited breath!

Woohoo! The battery has arrived and is on the charger as I type. Will have photos and whatnot after I've gone through the initial charging and discharging.
What I can say for certain is that the I-9003 battery fits perfectly into a standard Samsung Vibrant. No issues whatsoever.

Thanks, dude, for your info! I would be going to the shop to get one if you review it positively. I think I will have the "Purchase" button under the mouse arrow!

Funny quote from the second review, "These third party batteries come in two flavors – one without an extended back cover and another one with a back cover, which usually adds a couple of inches thickness to the phone."
Could you imagine if it was a couple of INCHES of thickness? It'd be almost as thick as it is wide
Doing a battery drain test now. Had my phone's screen on nonstop for 2hr30min, and the battery is down to 84% (though probably slightly inaccurate still). Will see how it fairs after I've charged and discharged it a few times. No, not from 100% to 0%. From 100% to 20%. Don't want to kill my battery.

Day 2, barely used my phone today, and it's at 84% with 18hrs of time away from the charger. Screen on time of only 16 minutes. The battery is definitely lasting longer, so I think I can safely say that this is a legitimate 1700mah battery. The real test will be how well it works after a few weeks, though I have high hopes.

I've just ordered mine! It won't ship until august, the 8th.
How is it going with your battery? Doest it last noticeably more?

Just lasted over 48hrs on one charge with light use. Mostly texting and some very brief gaming and market updates. Wifi and bluetooth were on the entire time. I'm definitely seeing a noticeable improvement in battery life.

Added link to the battery and website. I feel like the 1700mah is a little conservative on their part. It feels like I'm getting more battery than the rated 200mah difference would allow. Anyway, loving the purchase, and no issues so far. Will keep everyone posted if it suddenly bursts into flames, or bakes me a pie.

Thanks for posting your results.
I've been having trouble getting my battery to last more than 24 hours. :/
Though the latest releases of CM7 seem to be the problem. I was getting 24 hours easily with other roms..

So this 1700mah battery fits in the vibrant with the original back cover?

GTMax 3500 mAh battery - Poor battery life still

I was wondering how many people got these on sale(12 bucks on amazon) and what results they got.
Ive had mine through a couple charge cycles now and im not impressed at all, doesnt feel like its doubled my battery life.
Im at 80% after 2 hours, with only 16 minutes of screen on time. This might actually be worse than stock. The battery summary doesnt show any major drain from apps, and go launchers running app list doesnt show anything out of the ordinary either.
Im running Faux 0.9/Juggernaut 4.1/Litening theme
Im not sure what else I can do, battery is draining ridiculously fat.

It could be just be a defective one. Some custom roms dont recognize the batter stats properly as well. Try exchanging the battery for a new one and also try a different rom. Also try Wipe Battery Stats in clockworkmod recovery.

Hmm, thats kinda scary, would reflashing a rom from scratch fix that?
Also, google has stated wiping stats does nothing, thats a recent development.
As for exchanging, its from amazon, it took 3 weeks to ship this one to me lol.
It might be defective, it did take 9 hours to charge. 3500/650 should be ~ 5.3 hours, but maybe this is why it was on sale for 12 bucks.

Yes, the myth was that wiping battery stats improves the overall battery life but I was not saying this in hopes of improving it. I was just saying to see if it will correctly display how much battery life you have on your rom because one time I had a problem where my battery life stayed at 100% and after wiping it it correctly displayed how much I had left.
If it takes 9 hours to charge then I think its very likely that you do have a defective one. Rechargeble batteries tend to show that kind of symptom when you charge it often without letting it drain first. Try completely draining your battery below 10% and fully charge without stopping (dont pull the plug). If the battery life is still the same and it still takes around 9 hours to charge then I think its safe to say you do you have a defective one.
Also, please double check that the particular battery that you have is compatible with SGS2 Hercules model. Look at the battery information and compare it to the stock one. Make sure the voltages match.

I flashed Mr X's kernel, since Faux has been off since 0.07 for me.
When i charged it last night, it was from 0%, and it took around 3 hours to reach 34%, so im estimating the 9 hours based on that.
The stickers on it say 'Replacement for Hercules T989' Li-Ion 3.7v, i dont have my stock battery atm so i cant see if its the same, ill check that later.

I find it faster to charge using the usb plug converter instead of off the laptop using the usb cable. If I were you, I'd just use the stock battery until the new one ships in. I believe that's your best bet.

I may not even seek a replacement. It was 12 bucks, shipping would cost half the cost of the battery, and it would take them 3-4 weeks to ship another. The original order took 3.5 weeks to be delivered.

Well then, they shouldnt sell it in the first place. Now I'm wondering what kind of reviews it got on that site.

Peal off the cover of the battery. It should say how big the battery actually is. I highly doubt its 3500. But you never know

I was about to say this. You more or less likely got a fake Chinese battery that claims it's "..." mAh, but in reality it's significantly less. I've seen this happen too many times on the EVO 3D forums.

Here is one of the reviews: Looks like the same story as yours.
2.0 out of 5 stars Lasts same as the original, January 19, 2012
By Sunny - See all my reviewsThis review is from: GTMax High Capacity Extended Replacement Battery (3500mAh) for Samsung T-Mobile Hercules SGH-T989 (Package include a Neck Strap) (Wireless Phone Accessory)
I was excited to get this battery thinking that it would atleast give me one and half times more backup than the original. However, the backup i'm getting is not any better than the original battery. I will see for a couple of more days and if it is still same, i'll move back to the original battery and keep this one as back up. Help other customers find the most helpful reviews
Was this review helpful to you? Yes No Report abuse

Most cheaper priced batteries out there engage in false advertising. Don't believe the mah numbers you see even if they are the same as the stock oem battery. Its cheap for a reason just like the fake micro sd/flash drives for sale at Ebay. There are also shady vendors in Amazon who pump up their own ratings by leaving positive reviews especially the "ProdiCell" cell phone battery brand. With the exception of Seido and Muge, I would only stick with Samsung oem batteries. The Samsung Nexus extended oem 2100 mah battery is really good for $24.99 (50% off 49.99 at the Verizon store). I do see the extra 14% life. I went 34 hours the other day on stock 2.3.6 before my phone died. I actually ran 30mins of video at the end to run out the charge.

Ill try this out with synergy, since faux i heard was a drainer, and if no luck ill stick my stock battery in and continue to use my ballistic case. Ill also give it one more day.
Never tried an alternative battery till this one, and if im gonna go bulky again ill get that 3900 mah mugen, since that appears to be the real deal.

3250 mAh battery review (stock battery size)

It's getting late......after a long day waiting for this 3250 mAh battery to go flat, here is my review for what it is worth.
I have been searching for a month to find a battery that had the capability to last me all day. Not a bulky one! One that would fit within the original case. Not make my phone look pregnant.
I wanted a battery that i could Take off charge at 8am being able to last me all day, with LIGHT to MEDIUM usage (not heavy use!), right up until I went to bed at 10 and put it back on charge.
Is this the one??? (battery photos below)
I sourced this one. It just about fits the phone. I had to peel the battery label off at all 4 corners to get it in. It's fits in fine with standard Samsung back on. No bulge. I put in straight into my phone and charged it up to 100% then took it off charge and restarted the phone.
I'm not expecting amazing results on this first drain as I am more than aware it will take 3 to 4 cycles to gain it's full effectiveness. I am however expecting it to beat my standard battery display time on this first drain as it holda 34% more charge and then improve again after 3 more days use!
My stock Samsung battery lasts normally 4 hours display time with light to medium use. I have google location turned off, brighteness to auto and i am running gingerbread LA6. Full Samsung stock fresh out of the box. No root. No mods at all. And I have all the Samsung crap turned on and registered. I have google email with 2 accounts running. I play the odd game, and text and email like crazy. I used Ebay app heavily and also surf the Web lots. There are widgets on all 7 screens running and I always have a heavy usage live wallpaper running.
Phone finally starting to go flat... I will take screen shots of battery use and upload them. With my finally thoughts and finally 1st battery use screen shots as soon as it goes flat.
And obviously I'll look forward to your valued thoughts and views and make use of your experience as I'm new to this.......hopefully won't be too long!
Bye 4 now
1st day results in.
2nd day results in..

Ok..finally ran out of juice.
Remember this is not scientific just based on my daily normal use. But I did use my phone near enough full time today to make it go flat to see what it could do.
Again this is the first charge out of the bag. And I am interested to see how it gets on over the next few charges.

This has been going on for years on Ebay. Fake batteries & fake memory cards from China. Don't know how they get away with it, but I suppose money talks.

Please keep us updated. 5h 19m is my best display time using the Anker battery.

Try the Anker battery, im seeing about an extra hour of display time over the stock battery.

That's exactly what I've found with this battery on the first cycle today. I'm hoping that will improve over the next few charge cycles.? We will see

I'm actually quite intrigued to hear about this...my boyfriend uses a non branded battery from China for his Galaxy S2 and he's had no problems with it seems. I think he may have got it from ebay too. Combining that with a rechargeable case he never has to worry about recharging his phone. I hope this one works out well.

When I had my SGS2, I bought a 3,500mAh battery from eBay. It lasted longer, but not as long as I expected.
I tested it with a battery analyzer and sure enough, it was 2,413mAh. I bought another two, those only measured out at about 2,100mAh.
Those high mAh ratings you see on ebay batteries are fake.

No fake as in false advertisement! That's not really 3250 or whatever mah. If it was why wouldn't Samsung have made a 3200 or 3500 mah stock size battery? I can get 8 hours and over 5 hours screen on with stock 2500 easy. Usually mine goes all day with 4-8 hours music and 3-5 hours screen and last from 7am to 10pm ... its a scam that battery is maybe 2800 mah if that .....

Samsung OEM 2000mah extended battery

Hey y'all,
new here to the gnex forums from nexus s and I just wanted to share with y'all my experience with this battery.
Well, I'm on my third deep cycle to initially condition the battery and I gotta tell ya...
IT RULES.
I bought the battery after reading some reviews giving it decent feedback. It's on ebay from a company seller called "ShimShop".
It arrived in just about a week and I'm very satisfied.
The battery and extended door make the phone feel slightly heavier and more solid in your hand, It fits in both commuter and defender series otterboxs, but I suggest commuter.
I've been throuroghly impressed today as the battery has only drained 10% in 7 hours with 30 minutes of screen time. All my sync settings are enabed, running stock aosp 4.1.2 alongside franco's m6 kernel with his optimized settings.
I encourage EVERYONE to buy this battery. The stock gave me decent battery life, but this one seems much better thus far.

There's already a thread about it which is a couple of pages long.

It seems much stronger than the 1750mah, even though its only a difference of 250mah. It literally lasted me 48 hours with 4 hours of screen time, It's taking me forever to get through the initial deep drain cycles lol

Same here, I can get almost 4 hours on 2 days of battery. I do disable location tracking though and only turn it on when needed.
Keep in mind guys, that you're coming from a well used 1750 to a brand new 2000 so the difference will feel much greater.

Hey, I just bought one from the same seller. Won't be here for at least a week though. Thanks for the recommendation!

Will a new original Samsung battery improve battery life after 2 years?

I've own the SGS3 almost since launch day. Soon it will be 2 years old.
I'm getting 3 hours SOT and 24 hours total.
I'm thinking of buying a new original 2100 battery to see if it improves battery life. Would it?
Anyone has tried this?
Thanks.

I haven't tried it yet since I'm hopefully getting a new phone soon but I do believe it would help, maybe an extra hour SOT because I know my battery was amazing back 2 years ago and now I get the same times you do if not worse.

After a year on mine I was only getting 1700mah, So now I get a new Anker 2200mah battery every 6 months because they are just as good as original but do last longer.

Theoretically yes! battery life should improve, as you will be having a new battery.
My battery is just over a year old and i get around a 1d12h worth of battery time and roughly 3.5 to 4 hours SOT.
I recently bought a Pisen 2100mah battery off the internet and for the same SOT i got more usage. maybe 1d 20h nearing the 2d use.
n.b; wifi is always on. i use 3G for like 30 mins during a day

from what I've heard, newer generations of batteries, like ones that ship with SGS3, should not be drained to 0% with phone shutting down. it was advised to charge at low percents like 1% to 5% while phone is still on

Of course it would and if you dont have problem with size and weight i recomend you to get samsung's 3000mhA battery. Why not getting a bigger battery

It depends how old the battery is though. All Li-ion batteries degrade over time, even if they aren't used. So if you get a 2 year old battery, that has been sitting on a shelf somewhere, it won't help as much as you'd hoped. Depending on the temperature and charge level it was stored at, it could have lost a lot of its capacity.
So the trick is to get a newly manufactured battery, which isn't so easy since most sellers don't write this information.

Since a bigger battery means the battery is thicker,the original back cover wouldn't fit,then you need to use a specific cover which would make your phone heavier.
Right now I am in this trouble,I got a Onite 4500mAh extended battery with a blue cover,hopefully it's a great product, shipping as listed and battery performs exactly as listed,I just don't like the cover,it made my phone looked heavier.I was wondering maybe I should choose a power bank and put back my OEM one on.

This is true. You also need to account for your usage. If you do a lot of activity that heats your battery up (games, navigation, etc.) Then even a shelf stored battery will help since heat is another Li-ion killer.

My S3 was 2 years old in May of this year. I have been having issues with the battery and charging. My USB charging port has the classic loose connection issue as does the headphone jack. I see the fix and YouTube videos to repair but have not yet done that. I last week got my new OEM Samsung battery and the external charging kit. I just upgraded to Kitkat 4.4.2 NDA8 despite being eligible for a new phone discount from Sprint. My S3 is a 32gb unit and I will not buy a S5 with only 16gb, no way no how.
The new battery is performing very well. It is so close on updating to 4.4.2 that I can not be certain that there were not issues with my rooted 4.1.2 build after so many months. For sure the new battery is lasting longer. I think it was worth the $42.03 spent on the charger and battery as my USB port is in question and I can always swap batteries and charge with the external charger.
My S3 has a new lease on life and I can wait for new tech before upgrading. xda developers forum - root - and the desire for liberty is a powerful combination.

why not try using wireless charging? the qi reciever + charger should not cost you mote than 35 bucks. and you can still use your current battery, battery cover, & nfc, unlike powermat.
