Is it me or does the OP say in his title that it's about a 3500mah battery and then discuss the 2500mah battery. What's the 3500mah battery tag line about?

It's definitely a 3500mah battery. Just an typo I'd assume.

The back is thicker than the phone.. no thanks I will just continue to carry a spare battery.

These kind of batteries suck. If you need a decent backup just get an external battery. You can get an 8900mAh external that will last you more then you need. I always use mine when going on hiking or longer trips.. Generally where you would have a backpack of some smaller stuff. You do not need something like this for a days worth of common use.

I had one of those for my hero, get a big boost in life,. I went a three days without charge

What the hell is the point? I am getting nearly 20 hours of life out of my stock battery with two days of business use, and wifi. That looks awful as well.

You must not really use your phone like I do. Started at 8 today and its now 11 and im down to half battery even with overclock widget clocking it to 200Mhz when the screen is off
I bought one of these when the g1 came out and it gave me about 2 days off the charger. But im not sure how well this is gonna work with this phone. I really want to know how it worked with people who bought the smaller battery

If you dropped down that much you need to check your syncs and what using data. Is your phone set to cdma? I'm at 87% with 5 hours off the charger. Might as well solve whatever is eating up your battery first.

I take my phone off the charger around 6 every mourning and I don't lose the first bar till 1030 or so.that's with lots of text, internet, and some phone calls. Not a complaint here

I remember everyone was talking all this hype about the extended Seidio battery for the Mogul... I bought one... and was completely unsatisfied, I sent it back in, the mfg, acted surprised and sent me another one.. .Honestly even the replacement was exactly the same.. The Stock OEM battery lasted longer, and was more reliable.
Unless something has changed with Seidio since then, (which I highly doubt) I won't be "upgrading" my battery -
- I'm with the other member, I'de be more inclined to get some kinda external battery, or something. Too bad the USB connection changed on this new EVO 4g.. cuz my IOGEAR AA battery emergency charger is SICK! hmm.,.. actually i'm going to look for a USB converter, so that I can keep this iogear around.

Woah! I've been waiting to finally see the design on this as I've owned Seidio extended batteries in the past on other devices. The design on that back is a definite no go for me. It's horrific! I just can't F'up a rather well designed device with that hunchback. No way!

will people start complaining when they want 3 days of batter life? And do you guys not go home at night or day or evening (depending on when you work) to charge your phones? my phone with heavy use last about 8to9 hours.. and light to no use 20hrs.. i charge it every night..

i have the same battery used for the hero from seidio, so i hope they give the option to purchase just the back battery door. If not, i will have to wait for nakedcellphone from ebay to get his Mugen extended battery line (which have very decent door designs) and he sells em separate.
No need to drop 60 again, right?

had one for my htc diamond.. ive been checking the site everyday for that.. the back is bulky because of the battery size but like whoever stated.. you can go nearly three days without a charge depending on use.. i love those batteries

Wow. I guess it works for some. Personally I keep a micro usb cable at my desk at work. That + car charger and I'm never far from a source to charge my phone

1800mah eBay Battery Test

So, with all the chatter about crappy batteries on eBay, I figured I would try some and give them a half way decent testing. This was far from scientific, but I didn't feel like putting any more energy into it, and I don't have the equipment to test them otherwise.
I got THESE mostly because the seller is in the states, so it wont take 94 days to get my stuff. Also cause they're red, which makes them 146% less likely to suck. Note: I offered the guy $20 plus shipping, and he accepted that evening.
Before testing, I gave the new battery a 100% charge, then full discharge, and full charge again. I wiped battery stats, then rebooted and began the test. I did the exact same for the stock battery, but it may have a disadvantage, as it is a few weeks old. Maybe I'll test again in a while, if I get bored enough. For this test, I ran the Evo OC'd to 1228 on performance profile, set screen to full brightness and to never time out, streamed Pandora, and continuously downloaded from Dropbox. Running VaelPak 2.2 with Kingx #11 kernel. There were some variables to this, as I did use the phone during these hours, some calls, texts, browsing xda, etc. I tried to keep my use similar between the two tests, hopefully I did.
Well, how bout some pictures and results, eh. Stock 1500mah HTC battery first. Time from 100% to 10% was 107 minutes, time to shutoff was 123 minutes. You'll have to excuse the time since boot count, as I forgot that I had a SetCPU profile set to drastically under clock when the battery gets low, which caused the phone to freeze up since it was doing too much at once.

And the 1800mah eBay special. Time from 100% to 10% was 139 minutes, time to shutoff was 145 minutes. Not sure what to make of this battery running through the last 10% so quickly, but oh well. Would be nice if this went away as time goes on, but I won't really be running it down that low normally anyway.
To conclude, I guess I didn't get screwed on these. Based on my non-scientific test, these batteries last about 18% longer. Which is pretty much what you would expect from a 20% larger battery. The biggest thing for me is that they fit with the stock battery cover so I can continue to use my Otterbox and car mount. Now, this was only one test, time will tell if they are really any good. I don't feel like working at testing any more then this, so I'll be happily oblivious to any degradation from these cheap batteries.

just got one of these cause i feel like my battery is defected or something so ill check this out extremely fast ordered saturday recieved today monday

thanks for the feedback on the higher rated batteries. I don't think the ebay batteries are crappy at all though. They work just as well as the stock battery for me. Had one go through the wash without any damage.

I've been using these red batteries since July. They definitely last longer than the stock HTC battery, and have not yet deteriorated in performance.

well hopefully mines gonna do good. charged it and its already down to 94% in 30 mins and dropped 5% almost immediatly after i took it off the wall charger then put it into the phone. but after that its only gone down 1% so 94% battery in 30 mins :/ running myns 2.2 with battery tweak

It will do that until you fully charge it a couple times and wipe battery stats, if you have amon ra recovery anyway.
Hey... I think this thing makes phone calls too!

ive been using the same batteries too for about a week i think they are well worth the price. definetly last longer than stock red HTC batt.

Well my offer of $20 was declined. Not sure how long i want to wait to pick this up.

battery is by far way better then the original from what i can tell but havent done any significant testing

I would like to have 1, but I don't need 2. Wish I could find someone to go in halves w/ me. Preferably someone local to Nashville, TN. Any takers??

Well I got two of them from his regular web site. We will see how they work out.

Ill go in half with you (not sure how, though?), but I live in the Nashville area.

I got the 2 battery package with charger on eBay for $26 via "make an offer". I just scrolled through the feedbacks to see the lowest price they accepted... Charging now.

I just grabbed one of these batteries and the wall dock and I'm getting roughly 18-20% better battery life, good stuff for the money and no issues thus far.

Anybody want to lend one to the batteryboss.org guy for some scientific testing? If not, I may see if I can get 2 for $25 and send one in.

Well, if you don't have these batteries already, the value ship has sailed. Seller got greedy. They are now $60 for 2 batteries and charger on ebay, and $100 on Amazon.

Anker 1700mah battery

Has anyone tried these extended batteries? The 1900mah Anker batteries are popular for the Evo 3D but I just did a search in this forum and couldn't find anything.

i have one but not in an evo,i have an htc glacier and my battery las 2 h longer that the stok ****ty one

A few folks in the office here got them for the Evo's and one let me try it for a few days. HUGE improvement over the crap stock battery. I would definitely recommend it.

I think that I might try one myself, did you get this battery yet?

My friend ordered it but has not received it yet. I use the same brand in my Evo 3D and it's noticeably better than stock.

I replaced my original evo 4g battery that was over two years old with this one and I noticed a big differents in battery life. Also only payed $15 for 2 battery's and a wall charger off eBay.

I just posted a thread about these actually, I highly recommend, amazing batteries.

I've been using one of these (bought the 2 pack with charger) for roughly 6 months, and have been very pleased with it.
I can't confidently say that it is much better than a NEW stock battery, but considering my stock battery was over a year old, the Anker definitely improved my battery life, vs the stock old one.
I was hesitant about buying a non OEM battery, but I'm very pleased with mine, and for the cost was well worth it.

I have to +1 these being amazing batteries. Got mine for $13.99 on ebay with a desktop charger. I have gotten 24+ hours out of one charge. Highly recommend it!

I should be getting mine 2 pack with wall charger on monday. Can't wait!!!

Got it in today!!
The charger is interesting, it should fit just about any battery as the prongs will slide left and right, where ever the + and - is on the battery. Then also the bottom part that holds the battery is on a spring and you just pull down the length of the battery.
It charged one of the to 89% pretty fast, probably an hour. Had to take it off for a emergency call.
Ill be able to give a better test soon. I need a fresh flash of CM7 anyways, too much bog and FC's. Probably not good when the main process FC's.

I am still running the same battery that I took off the charger when I made that post. I am at 1 day and 3 hours with 30% left. I haven't really been making any calls, just some txts, most of it was me playing around and flashing different things to make my ICS experience better, using drew's P7. The battery went down fast from 89% till about 60%, but the other battery I got took about double the time to fully charger than with how long this battery has been in my phone. I am excited so far, looks very promising. I think this was a worthwhile purchase, simply for the wall charger, to charge any phone battery!

I'm getting pretty great results with these batteries. I haven't been using my phone too much and lots of idle time. I took a fresh battery off at midnight and went right to sleep. I slept most of the day. When I got up it was at 81 I think after 14 hours. I used my phone here and there for some texts and some small phone calls. I started installing lots of apps and played around with Widgets and settings, it popped down to 59 around that time. I installed juice defender also and I think it only went down a few notches all night till the morning. I haven't done much today besides a couple dozen texts a short and then 20 min call. I'm updating a bunch of apps right now while typing this, its lagging a bit so its slow and took me a few min and lost 1% but I'm also updating 11 apps at once
I am running drews P7, I have been running unvisible tweaks, but I just installed the nifty tweak zip and popped in a fresh battery, so this may be even better battery life now that I got juicedefender and the nifty tweaks. Cant wait to see! Im also thinking about running one of the KANG CM7 roms, as I already got about this with stock battery, I think it could last 3 days if I went back to CM7. God, I can't wait for CM9 and custom kernels!!
Here is what my current up time is.

[Review] Qcell battery

I have never done a review before so any information I am lacking feel free to ask ^^
The batteries I bought where found here: amazon(DOT)com/dp/B00757ER00/ref=pe_175190_21431760_M2T1_ST1_dp_1
Model: Att siii - pebble blue 16gb
Network: 4g (non lte, the H stuff)
Wifi: off
Bluetooth: on
GPS: on
Brightness: auto
NFC: on
Rom: Cm10 beta
Kernal: stock
O/Uclock: stock
The batteries came in a small white box and the label on the batteries where upside down. The charger and packaging all felt cheap but it was to be expected for how much I paid. The initial charging of the battery (both) was about 2 hours until it was fully charged. I'm not sure what percent they came charged at as I forgot to check. My first charge (will post screens) lasted WAY longer then my OEM battery. I'm not sure if I have a bad battery or if these are just way better. Humorously enough the screen shots I am posting also include my alarm going off for over 4 hours strait... (Yeah it was going off at work and it took half the shift for them to figure out it was mine... lol :/)

What was the "screen on" time? Are these batteries 3.7 or 3.8 volts? Did you use the external charger?

Ordered mine yesterday. We will see how they do.

Yes i'd also love to know the screen on time seeing how thats the most important thing when looking at battery life.

I received mine last night. As the op states comes in a cheap white box. Batteries don't look like a premium battery due to a really really glossy sticker the battery is wrapped in. I posted some pictures just in case OP wants to include them..
I will also update my post later based on my review.
Side note: I discharged the battery until it died and charged it up over night with the phone off. When I turned the phone on it showed a 98% battery.

3.7 as stated above. My screen on time is a minimum of 4 hours daily just due to my commute to work. I'll drain the battery again today though for sure. I would assume it was around 5. I used the charger it came with.

Im just wondering where you guys are ordering from? Ive been looking all week, Amazon is the only seller I could find and they haven't had any inventory since I started looking 3 days ago

You have to keep looking because they always restock their inventory. They only sell on amazon. The first time I wanted to get mine they were sold out. I had to wait a few days before they were available again. As soon as they are available get them because they sell out quick.

Polarcell 2700mAh great battery life

A few weeks ago I purchased one of these Polarcell 2700mAh batteries.
It took a few cycles but now the battery life is amazing. Yesterday I had been texting and chatting on skype pretty much all day and I was surprised my battery wasn't empty yet so I went into the settings to check my screen on time.
My screen brightness was on auto and I don't have any apps like noled that keep the screen technically on but don't consume a lot of battery. All I did was use Skype and Gosmspro.
So if anyone is looking for a replacement battery, I can recommend the Polarcell 2700mAh..

Bravo. Although a stock battery can be as good as new.

Just bought one today for my galaxy s3 , i was confused about which battery to buy and how it would act.. I just saw your post now, so i feel that I did a good discussion :good:

screen shot
Could you please post screen shot of your About Phone with details of Rom/Kernel you're on? Thanks

Does it lose its charge in the next few weeks?

are these batteries the same dimension as the stock one? I mean, do I have to use a different back cover(bulky phone)?

@Octhellio which rom and kernel do you use ?

Been using a polarcell 2700 for a few months - and no matter what rom/kernel(both TW based or CM/PA/AOKP) I have been using - it holds its charge extremely well Worth the $$$

Great topic!
Do you know if the PolarCell is better than the MoTec?

I have search for reviews of Polarcell batteries, and found several happy users in many others phones.
So I bought two units on Ebay, one for my phone and one for my wife's phone.
I think it should be much better than these batteries from China...
Well, at least this seems to be made in Germany.

Are you using an AOSP based ROM or TW based? That's quite impressive is AOSP. I have 3 batteries and have my cellular signal off with brightness often at the lowest and get 4.5h maximum (batteries not too old).
Your android system usage is a lot lower than mine, what were you using it for?
Can you please weigh it compared to the standard battery?

estimate date to delivery?

A few minutes ago I purchased it too, delivery is scheduled between the 23rd and the 26th of this month: D

I'm charging the battery! How many hours must be under load?

After 42 days, finally my batteries has come! (It´s sadly live in Brazil because of dollar conversion and time to receive Ebay things)
I put it on my phone and tried to use the 58% of charge that is inside.
I played 3 games and really feel that the battery discharge much more slower than my older one.
After 2h18m of screen time, it has 28% left!
I used 2h18m games/internet/youtube and it only discharge 30% (it´s a record on my phone)
Buuuuuuuuuuuut, it´s only the first impression...
Today I will fully charge the phone and do some tests...
I come back soon with my impressions.
Best regards
