[Q]Legit 3500 mAh battery?

I want to extend my battery life. Wondering if anyone's tried anything but the stock 1850 mAh battery? If you have, please provide a place to purchase it. Thanks

JUST GOT ONE IN FROM CHINA...WILL REVIEW IN A COUPLE DAY...IT DOESNT SEEM TO READ THE TEMP RIGHT...trying to kill it now ( i know it doesnt matter but i like to see how quick i can kill it off)

Those batteries are a scam..why bother getting a bigger one anyway, not only do you lose Nfc, the stock battery already lasts a whole day easy

I don't get the problem with the battery, I can watch shows and movies all day at work and still come home with at the worst 40% battery life

I dont use NFC anyway, and its 18 bucks big deal...stock battery might last you a whole day but it only last 7-9, 10 at the most for me.
I want a battery that i can use my screen to 100% display setting, let people use my internet via wifi hotspot and not have to worried it die in 3-4 hours. i dont care for aesthetic much it's a f****** phone.

Innocell 3800mAh Super Extended Life Battery
I have used Seido Cells with G1's before and they were still running just like new after 18 months of heavy usage, twice the battery life over stock. The case looked better on the G1 as the back was flush. On one of the phones the case did crack and break after a 3 ft fall. It was a cheap and quick replacement from Amazon, under ten bucks if I remember right.
The one offered is a 3800mah at 69.99 and shipping now.

I really want a better battery too, I'm waiting for ANKER to make one for the t989. I have no idea how people manage to squeeze so many hours from there phones on this stock battery, but I usually go 5-7 hours before it dies. I'm not a heavy user but I do have my screen to 100% all the time. I don't mind carrying spare batteries.

LOL - what a job

If people are really concerned about hte battery life etc, just get one of those mobile chargers. They will charge everything from laptops to cell phones...they are called power packs.
first link on google...came up with this. http://www.amazon.com/Energizer-XP4000-Universal-Rechargeable-Power/dp/B0029U2WTG

There is a lot of fraud on these extended battery

Yeah i agree, there is a lot of fraud with the battery packs. Someone should regulate them and make sure that what they advertise is true.

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..
Photos of battery weights...

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 .....

Best battery upgrade

Hi,
I would like to know what is the best battery upgrade. Sometimes i need to use my phone for geocashing for more than two days and it is very boring trying to find time for waiting for charging. So I'm looking for best solution like extended battery or something like that. Size is not important for me, but i want something quality. Can you help me please ?
Thanks

Since size isnt a problem, id say.. get the Mugen 3200mah battery.
The quality is good and it has almost twice the capacity of the original.

Official samsung 2000 mah is pretty good. I get about 30% more usage on a full charge.

I bought a 9.99 3000mah battery from Ebay. Cut a hole in the back of my cover so it would fit. Anyway I'm getting over 36 hours between charge with moderate use. Atm I'm on 55% battery and I'm on 18 hours 16min. Data on. Sync on. half brightness

Extended battery upgrade

Hi there,
My stock battery is quite dreadful, I get about 1 or 2 hours screen on time. I don't think its capacity is anywhere near 1800mah.
I just ordered a new battery off eBay, claiming to be 2300mah. It is not the One X+ battery, which is 2100mah. This was only £4 so I'm aware this could be poor quality. Delivery is Thursday, I'll be sure to post my comments about how the battery performs.
I also ordered a battery case (2400 mah), which has a flip cover, cost £14. I'm prone to smashing phone screens otherwise I would have gone for the crazy 6000mah mugen case. Delivery on this is very slow but again I will post a mini review about it in here.

I was going to buy that exact battery. There was some guy on youtube used that battery and he said that it's quite good. Sadly the seller does not ship to my country. I ended up ordering this

So I just installed the battery. At one point just before I put the copper sheet back on I realised I re installed the old battery haha.
Phone has been charging for about half an hour, and the temperatures are not good. 45°C. It is not because the copper sheet wasn't placed properly, since I can feel the heat on the back of the phone. I guess that is due to the battery maybe being poor quality (high internal resistance?), since it was only £4.
Sometime tomorrow I comment on how long it lasts compared to the old battery. Previously I could get 2 hours MAX screen on time. I think it should really be about 5 hours now, with a 2300 mah battery.

Have you received your battery yet? I'm interested to see how it performs, I don't think anyone else in the forums has got one.
After using this new 2300 mah battery for 2/3 days, I am still very disappointed with battery life. Battery life is still exactly the same, I get about 2 hours screen on if I'm conservative. I may try CM11 later to see if battery life improves. I am doubtful it will though, since it did not improve battery life with the old battery.
Going to run 'Nova Battery Test' tonight and will post results. Also have some screenshots incoming.

The seller said that I would receive it in 3 weeks time. A lot of waiting. And if I receive it, I would wait until I'm done with the exams before changing the battery. Maybe at the end of June. Haha. But the guy from youtube said that he got a large improvement using the battery now.

So today I've been quite impressed by battery performance. I got 3 and a half hours screen on time! Nearly double what I had with the old battery. This is still not enough to get me through a day (battery came off charge at 4:30, died at 11:30) but I am still pleased. Hopefully can achieve this performance consistently!

Battery performance is now poor again, 90 minutes screen on time. I don't know how I got 3 hours screen on before. Seems it was a one off? I am now saving for a new phone.

How's the battery holding up? I just got my battery replaced after two years from HTC repair centre and it seems to be as new. Got the same old 1800mah battery. I'll post screen shots after the battery has depleted to 5%

hi buddy check my last post in this thread... http://forum.xda-developers.com/showthread.php?t=2096459&page=22
overall the phone is as good as new... i am getting an average screen on time of around 3hrs and 15mins.. this may sound less, however i spend atleast 7-8hrs listening to music hence the screen time is less in my case. but if i reduce my music usage then the max i have got is 3 hrs 40 mins... pretty impressive imo... i might use it for another 6 months or so before upgrading,,,,

Yeah unfortunately.
I recalibrated the battery using an app. I might install a different recovery and clear battery stats from there.
The battery case has helped a lot. I'll post a mini review later.
