I got the battery, I didn't notice a huge difference but I haven't tracked it at all.

They're are lying to you. basically any battery that's the same size as the stock battery is going to have the same amount of power as the stock battery. The only way to get extra juice is to add extra bulk. However, Seidio makes batteries that don't add extra bulk. Those are rated at 1750 mah. While I still you won't get much more battery life out of these, there at least a reputable company you can trust.

Andida is suppose to be better than a no-name battery. It is a name brand, just a cheaper name-brand and known in China. I bought their 2000mah battery and it seems to be about as good as the stock 1500mah. Then, i found that BatteryBoss tested the Andida 2000mah and it actually tested to be worse than the stock 1500mah Evo battery. I wouldnt want you to waste your money. I guess Seidio would be the only option because Mugen didnt do to good either at BatteryBoss. Sucks too, because they are so expensive, but if you MUST keep the factory battery door and want more juice than thats about your only option. I bought the 3000mah ebay battery with extended battery door and it is just awesome!! Yes, it is bigger. But, its actually VERY nice and looks and feels good with the bigger cover. Oh, and it is hard to kill . I turned on every radio and streamed music over wifi to bluetooth speakers for hours last night trying to run it down and only lost about 7% in the 2 hour span of doing this....

I tried the Andida 2000 and was not better then the OEM battery. Also have the extended 3500 from ebay(10.00) and works well, go a whole day+ with wifi, gps, sync on with mild to moderate use. Switch off and on with the oem and extended.

The 2000mah battery is garbage doesnt last longer than oem bat like others have said. I bought a 1800mah battery from ebay. its been over 24hrs and Im at 22% after 2hrs of calls, 30 txts, 1hr web browsing, & 1hr of pandora, bt is on all day too! I highly recommend, here's the link
http://cgi.ebay.com/2x1800mAh-Battery-Dock-Charger-Sprint-HTC-Evo-4G-/250661324218?pt=PDA_Accessories&hash=item3a5c9445ba#ht_3914wt_807

The andida 2000 I purchased was a good battery but I guess I was one of the lucky ones. I currently have a 3500mah battery. I see that there are also 2000mah galiliO batteries now available. I was thinking of getting one and comparing it to the stock battery and the andida 2000. I don't know if the galilieO batteries are 2000mah or just the re-labeled 1800mah batteries that are all over ebay.

@snowplow
you say the only way to add more juice is by adding bulk, but then in the next sentence say seidio is able to do it without adding bulk? not really making sense there! seidios battery i believe tested to be in the 1400s, below the OEM.

Just bought 2 for $16 with a charger... So I'll let you know. Can't see myself being uber angry if it is the same as stock, as having a few spare batteries for mere pittance is great. Gotta love that eBay...
Galilio 2000mah. We'll see.

I actually got the Galileo batteries as well, so far, I'm seeing a little better than usual battery life. which makes me optimistic, considering you don't see the true potential until a few charge cycles, I just got them yesterday.

If you guys are running after market batteries here's a tip.
I have been running my Sedio 1800 mah (I know tested only comes to 1500) and lately my phone has been powering off on it's own. It happened to at the same time as I was running various gingerbread roms so I thought it had something to do with that. After some experimentation I realized that it was happening when I dropped my phone on the desk(ohh, yes I have a tpu case on the phone). I thought great, its a hardware issue and I don't have a warranty. Then after a long day streaming and lots of phone calls I needed to swap batteries and I installed my stock battery. I then noticed that my power off issues went away. I dropped the phone on the desktop 10 more times and no issues. So apparently the Sedio battery doesn't fit quite right in the phone, so wedged some paper at the top of the battery to try to give a little more pressure on the battery pins and that seems to have solved the issue.

the galilios are good batteries for the price, but i believe them to be closer to 1300mah based on my results vs stock.

Just got a "Galilio" 2000mah yesterday. I'll be seeing how it works out over the next few days and report back. It is blatantly for a TP2 but fits VERY snugly in the EVO, (almost too snugly) and is a pain to get in and out. I have to use the corner of my back cover to pry it out...but if it gives me more battery I'll be taking it out less...

I have the exact same thing!. I actually had to rake a razor to one of them and Shane off a little bit of plastic from the top of the battery. Just a tiny bit. Fits perfect now.

There's already a discussion regarding this battery and others at this thread:
http://forum.xda-developers.com/showthread.php?t=925298
That thread is more current than this one that started in Sept '10. Should we use that thread instead of keeping 2 very similar ones? Just a thought.

I have the Andida battery- worked great for a few weeks. Then I started to notice it would lose its charge fast. But this battery stated it was for the TP2- either way it fits the Evo. But when I had it on my TP2- it would hold a good charge.
I love the ebay 3500 batteries- great and still holding a charge (had it for almost a year). I use this one I am going on a long trip or Army training.
I have two of the Galilio 2000mah batteries- made for the TP2- no need to shave any crap- fits perfectly on my Evo. I measured both the OEM and the Galilio batteries- no difference. The Galilio is worth my $9- and I want that OEM look- I also ordered a white OEM Htc back cover. Read somewhere here in XDA- charge your batteries atleast once on a wallcharger- not usb. I find the batteries last longer.
Note, i did buy a generic 2000mah (non Galilio brand)- that was crap.
I have (2) 3500 mAh batteries, (1) 3000 mAh battery, (2) Galilio 2000 mAh batteries, (1) 1750 mAh Seidio battery... and others.

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?

I Want to Buy an Extended Battery But Which One???

Ive looked around abit and the reviews are mixed for all batteries.
I was wondering your guys honest opinion on a few ive looked at.
3500 mAh Gorilla Gadget: http://gorillagadgets.com/samsung-epic-4g-extended-battery-3500mah-with-back-plate.html
Hyperion 3500 mAh: http://www.amazon.com/Hyperion-Sams...4JFS/ref=sr_1_6?ie=UTF8&qid=1324412744&sr=8-6
Seidio Innocell 3300 mAh: http://www.amazon.com/Seidio-Innoce...8EYM/ref=sr_1_3?ie=UTF8&qid=1324412744&sr=8-3
Im mainly looking into Hyperion and Gorilla Gadget, Seidio is a bit expensive
i Currently can get 8-10 Hours with med-heavy usage depending on how much i game. i can probably get around 20 Hours with minimal use just texting and bare bones. im running Starskys Rom 1.5, Samurai 3.30 Ninja, NO OC/UV on VR l/0 scheduler and conservative. What would be the best battery to get out of those and is it honestly worth it?
Any suggestions are appreciated

I have been using the gorilla gadget battery for just under a year. I bought it because of the price. I still only seem to get 10 to 12 with heavy usage (work and personal phone) but with light usage I have gone 20+.
I am running CM7.
Keep in mind though it does take a nice light thin phone and bloats it. And it definitely adds some weight.
Doesn't fit in a pocket quite as comfortably as the stock battery Al though I have gotten used to it at this point.

How is it compared to the 3500 mah batteries

I've heard that the Samsung 1800 mAh battery for the Epic Touch works just as well as the generic 3000mAh batteries.

Yeah, id have to say the 3500, with the added clutter isn't worth it but that's just my opinion. The 1800 pops right in and lasts a good 14 hours with a lot of usage.
Another thing to consider is where the battery is made. My factory 1500 was china, and the samsung 1800 I ordered was from japan. The difference and quality is noticeable.

Here's the best option. The Seidio 3300 battery. This is the new version and uses all japanese cells, high quality.
But regardless of what extended batter you get, you must also purchass the Mugen extended batter door. This is by far the best extended batter door and feels perfit in my hands, I've held them all. Fits snuggly too.

And does anybody know anything about the Hyperion battery?

If anyone has some suggestions how about mugen power batteries compared to OEM?

I got a pair of 8$ 3500's with a "3 year warranty" off ebay, that came with extended backs and a 4$ cradle charger for the second battery.
I get 24+ hours out of the phone and can game endlessly by swapping batteries if needed.
also the big battery feels great in the hands.

Working at Boeing 12hrs a day, 7 days a week, I use the cheapy eBay extended batteries and covers and am able to stream solidly for at least 6hrs on each battery, which also includes the standard running apps in the background...SEVEN email, WhatsApp (which means I'm texting the GF in Dubai), TiKL and then the usual Sprint background services (voicemail, Market, etc that always run). I'm OC'ed at 1500mhz w/ MultiPicture Live Wallpaper running, always gettings texts and emails throughout the day. Point is, for $12 shipped for a battery w/ cover and a seperate wall charger for just the battery, I go through two batteries a day. One get close to dying around mid day, swap w/ the battery on the charger...rinse and repeat the next day

I highly doubt that...when I was still stock, I could kill my battery within a few hours just playing Gameloft games. I find it incredibly hard to believe that you're streaming Pandora for 6+hrs and still have plenty of battery life left. As for what is or isn't needed, those are the things I use regularily...some would consider me a power user, always running overclocked, screen on full brightness when I use it, etc...so I'm guessing you're the type who is more concerned w/ battery life instead of performance. You admit you used your phone a little bit for texts, I use mine all the time for texts, both using Handcent for friends here in the U.S. and WhatsApp for my GF in Dubai...we have different battery needs, but I can guarantee your 1500mah isn't going to last longer than my 3500mah battery, generic or not.

Largest capacity battery without extended case?

Hi, I was wondering what the highest capacity battery was without having to replace the back cover?
I know of the anker 1900mah, what about the Samsung 2000mah? Also, what do you guys think of buying no name batteries that are advertised as 1900mah?
I've bought no name batteries for my HTC incredible s before, I bought an 1800mah battery which gave me the exact same battery life as a 6 month old stock 1450mah battery, so thoughts?
EDIT: I'm a stickler for thinness so even if a back plate adds 1mm to it, i don't want it, I've had enough of my thick as stars HTC incredible s

the samsung 2000mah battery gives you a new back cover and makes your phone a little bid thicker, but not much. Most hard cases will still tightly fit
This would be your best option, as you are sure it will be 2000mah.
I myself got the 1900mah anker battery and dont really see any difference with it... It is about the same as stock. My 2000mah battery is arriving soon ^^
There are enouf pictures/movies of the 2000mah batter, there you can see how big it is I myself think it will make the phone easyer in the hand

Do instead of it having a bulge at the bottom, now everywhere is as thick as the bulge?

yes!
I only get 2.5 hours screen on time with data most of the time off with my 1900 anker battery, which is same/worse than default battery.
I think your safest/best choice is the samsung's official 2000mah battery. Do know that many slim cases wont fit anymore.
You can clearly see the size here:
http://www.youtube.com/watch?v=5tHvfEtsvUg&feature=player_detailpage#t=327s

Oh yes, since I'm getting a slightly bigger case along with the 2000mah battery, why not get something with even more capacity? What's the largest capacity that will fit in the back plate that comes with the 2000mah extended battery?

You can buy even bigger ones, but they will be 2-3x bigger in size.
And if 3rd party batterymakers say it holds 3500 mah, it actually is only 2500.
Size-quality wise, the official is the best by far!
And if you are really scared of running out of batteries when you are on vacation or something, just get a 2nd battery? This way you can switch battery whenever you want. And you will always have a spare fully charged battery with you

alright cool, thanks lots for your help, been mostly an androidforums Guy, don't come here often

I have quite contrast opinion and experience on Anker battery on my SGS2. It mathematically holds some 16% more juice, but actually performs with 20-25% improvement. My friend who bought one for his Note (both orig and Anker are 2500mAh) says Anker holds up 15% longer (orig would drain every day between 7 and 8 pm, and Anker holds for another hour and a half, approx). It fits your original back cover, and I think it is worth trying.

Oh that sounds good, but don't companies like Anker, Chichitec and mugen "overadvertise" their battery capacities? A 1900mAh would be maybe a 1500mAh and a 1800mAh would be a 1400mAh?
Oh and did you compare your Anker 1900mAh to a new stock battery or one that's maybe 6 months old?

get the 2000 mah battery from samsung, its great, doesnt make the phone any thicker but it makes enough of a difference mate!

Anker is not overadvertisig its batteries like some Chinese factories. When I first tested Anker, my stock battery was some 3 months old. You should know that Anker batteries (as well as stock ones) need some 5 complete charges to start to act fully with their capacity, so do the test not the same moment when you buy the battery, but after 5-6 charges. I am using Anker battery now 99% of the time, and keep my stock one at home, full, just in case I need the phone full urgently. Every time I keep stock battery in phone I can see how it's depleated faster, so Anker is still better than stock one, some 8 months after using it heavily.
My stock battery is always on 15-20% at the end of the working day (from 8am to 22h-midnight), empty by midnight on weekends. Anker can withstand one day + night + morning shift on working days, and full day on the weekend, with some juice left.
Oh, and I use battery circle with % on it, so I can pretty accurately monitor
how fast is my battery draining while on internet, watching video, playing games (you don't see the % during the game, but you see it before and after), calling etc.

I last saw one that made the s2 just 1mm thicker I will post it when I find it again

i think the best extended battery you could get without any noticeable/annoying bulges, is the legit 2000mAh from Samsung.. it does not cost that much considering that it is not some hoax and it also comes with their custom back cover for the extended batter.. I don't trust Chinese products entirely

Best battery for this phone?

So I'm looking for an extended battery. I came across this battery and wanted to know if anyone has tried it?

If not can someone direct me to an extended battery cover like it. I currently have a 3800mah very similar to this one

I found the best reviews have been Qcell and Trexcell for extended batteries. I just ordered myself a 4100Mah QCell on Ebay. Also make sure to follow proper conditioning.
Full discharge and full recharge 6 times. Leave the charger connected 2 hours after it has hit 100 if charging in the phone
Every other time after the conditioning don't let the battery die out.
Charge the battery around 20% don't let it drop that low and it'll extend it's life and will hold it charge
I have that same chinese generic extended battery. I got 4 with 4 covers for 20$ and they are garbage lol. I have had them for almost a year and they can't even give me 6 hours with 2 hours of screen time and thats after a 10 hour charge on them. My stock samsung 1800mah battery outperforms them already so i just tossed them out and I'm waiting on QCell.
Edit: Hyperion and Gorilla are good as well.

Yea I have a Qcell its boss.
