Available here! Who wants to try one first?
Me definitely! $50 seems like an awful lot to spend for an extra 200mAh though
I would but no money right now. Hey anything would be better off then the OEM 1300mAh =)
stock is 1400mha.
something tells me the stock battery have a higher capacity than those crooks using inferior cells while inflating the numbers.

You are most definitely right I bought one if those for my G1 and it crapped out within a year. Your best bet is to take your chances with the cheap batteries on ebay. You can get ten of them for what one from Seidio charges you. No knock on Seidio.

dunno where i saw it (somewhere here on xda prolly N1 forum) but some guys put every aftermarket battery for MANY phones up against HTC's stock batteries the astounding results:
NO aftermarket battery from ANY mfg. has EVER beaten HTC's stock battery...
(this is referring to batteries that fit in stock battery enclosure)
I agree after market battery might show higher numbers but not as good as the stocks ones

me 3 right under a year mine crapped out and it never seemed much better than my 2 year old htc it replaced.
I'm surprised, I've had good results with extended batteries. The one I got for my G1 did considerably better than stock. (8-9 hours versus 6 with OEM battery.)
I bought 2 1500mAh batteries with charger from ebay for less then $15 shipped. They last less then stock battery does (I kill stock battery in about 14 hours, the ones from ebay last me about 10-12 hours) but I always have charged spare battery now. Great investment IMHO, no way I would pay $50 for 1 battery, not even original HTC.
Hey Zoltair, What brand was the one you got that was better than stock???
Well I should hope that an extended battery would give you longer life then a stock...seeing as how its suppose to. I don't think that the problem is whether or not extended batteris last longer, because I would think if you bought an extended battery and it didint last longer then a smaller, stock battery..you would then return it...I think what people have problems with is getting what they pay for, price per mA and how much mA there really is...if your paying 50 dollars for a battery rated at 1400ma, your probably going to want all the mA you payed for...for example: (PURELY FOR SPECULATION, NOT REAL NNUMBERS) say you have a stock 500ma battery and you get like 4 hours out of it or whatever, and then you purchase an extended battery for 50bucks and its "rated" at 1000ma, yet you only get 6-7 hours out of it...? Then it would seem that it isn't truly rated at which they say it is... Then you get into how much certain companies value their own integrity, and how much they are going to inflate their own battery ratings to simply sell the product. Examples of this can be found on batteryboss.org ...This website obtains batteries and tests them, and you can see clearly, some companies inflate their ratings more than others... If you look at what the battery was rated at, and what exactly it tested at...they even break down price per mA...so if you paid 2dollars per mA for a 1500 rated battery and it tested at 1300..how much money are you losing? Purchasing an extended battery should be looked at like all consumer purchases, weight the pros and cons... and read reviews on companies, you can also seek alternatives such as previous post in this thread of having spare OEM batteries that cost 1/10th of an extended battery, yet they immediately doulbe your battery length..

No word yet on performance on this? Anybody get it? I don't want to go first, lol!
Well $49.99 for 1600mAh is high as hell and top of that from unknown source, might well as wait for Mugen power stock size. I hope whoever has this post data on it so we can see if its any good.
Got one of these for my N1. Definitely NOT worth the money. Don't notice any difference from the OEM.

HI
I will get my TB in next few days. (thank god, I finally get rid of my Droid 2)
the more thread I read, more thoughts in my mind. So I need some good advice.
I'm a real heavy user. (surf on net, GPS nevigation......etc)
I want to extend the time I use my TB. So I'm going to get some extended batteries for sure. BUT problem is.....what kind of batteries is good for me?
OEM batteries or seidio brand? And what Mah should I get?
Does oem batteries cause bad influence? (like my TB wont have normal function in the future)
And If I get some extended batteries, I will get the cover for it as well.
Will it cause the signal reception?
Yep, I know my problem is dumb. Cause I can't really accept any smart phone can't last a full day sage. (like my droid 2)
I use the HTC 2750 battery, and i get through all day fine. on light usage i get down to about %70 on heavy down to %40ish.
Be weary of OEM batteries with extended covers, ive heard some do not have the antenna built in. The radio signal antenna is located in that cover, so if you get one that is missing the antenna, you will have no service.
I would recommend the HTC extended battery.

To the OP - I've been using the HTC b2750 and case for a while, but I'm getting tired of its bulk and switching back to the stock phone battery and a spare.
With the TBolt and most of my other phones, I just slip a spare stock sized battery into the pocket of my wallet and swap batteries mid-day if I'm not any place where I can get some boost charges during the day. The batteries on the Thunderbolt are very thin; I really don't notice one in my wallet.

Doesn't OEM mean "Original Equipment Manufacturer"? That would mean an OEM product is one made by HTC, whether it's sold under HTC's name or another 3rd party's brand name.
Either way, the advice is sound, make sure you're getting a quality product that has all the working parts. I recently bought some 3rd party spare batteries for the Nexus S that were labelled as 1400mah (like the OEM) but when you peeled off the 3rd party label the batteries were only 1100mmah! Always buy from a reputable dealer.
I wear a clip holster and bought the extended battery along with the seidio extended battery case. Perfect match up for me.
Sent from my ThunderBolt using XDA App
I would choose the OEM HTC extended battery. I have it now and I get by all day on it. Usually by 10 pm, I'm around 30%.
I've had a Seidio extended battery for the Incredible and wasn't impressed by it. I believe it was the 1750 mah? While the stock was around 1400, I couldn't tell a difference between the two.
Sent from my ADR6400L using XDA App
The best thing you could do is to root it and run dad bamf stripped v1.1. I use the stock kernel and get 2 to 3 times the battery life as stock, Imoseyon's lean kernel with battery saver may even give better battery life but I haven't tried it yet.
I'm going back and forth between the Seidio 3200 and the HTC 2750. I think I'm going to get the HTC 2750 battery tomorrow... I just hate the face that after spending $250 on a phone I have to spend another $50 to get close to the battery life specs posted on HTC and VZW's websites...
Most people in this section will say get the HTC battery. I'm actually going to probably get a mugen power slim battery. I've been looking up on them and they seem to be pretty good.

If you are a heavy user, you will love the 2750 HTC Extended battery, I got it, would say i'm a moderate to heavy user, and i can get 30-40 hours out of it. I love it
I initially didn't like the bulk of the 2750 extended battery especially after putting the seidio active case on it but after playing around with the stock battery I now prefer the contour fit in my hand with the extended battery. The biggest downsize now is the weight. This thing is heavy but well worth the weight.
My advice is to order it from verizon. Call up and request a discounted price, I paid 20 for mine.
Sent through the interwebs.
I would go with the HTC 2750.... I got it and it comes with the contacts for antenna
1700 battery
I ordered a 1700 battery that fits in orignal back. It is coming in the mail tomorrow. I'll let everyone know the results...
Do not use trash batteries. Stick with OEM batteries made by HTC. The 2750mah battery is fine.
I purchased a 3500 battery from Amazon with the cover and it does NOT have the antenna in the cover. I get a 3G signal but no 4G. Sending it back today.
i got one on ebay for $10, the pictures indicated it has the metal contacts in the battery cover. hong kong express mail, delivery july 15th at the soonest -_____-
OEM 2750 for sure. Like some of the other people in this thread have stated, third party batteries just have risks associated with them, and the potential benefits usually aren't worth it.
But if you do decide that the OEM one is too much, just make sure you don't get the ebay offbrand batteries. Most ebay batteries that are advertised as "extended" and sound too good to be true (i.e., 3 batteries at 1800mAh + charger for < $20) usually are, and have actually less capacity than stock.
After a few days.......
I start with stock battery in the beginning.
Gingeritis rom installed. Battery was really bad for first 2 days.
Lost 10% per hour.That's bad.
After 2 full days usage, battery life gets better, It can last half day.
Today. I got my htc oem battery from verizon.
Amazing battery life. 100% for sure.
I think there should be no problem with battery life now.
My TB is really great now.
the reason why I choose 2750 battery is you guys can see that the cover get more dmg with times you open (switch battery). So I deside not to open it too often. I think it is a right choice now.
BTW, before you go to eaby, go to verizon store, give them your accout to check discount. ebay doesnt mean the lowest price. I got my battery+cover with 40+tax.
or you can save some money and just buy a bunch of cheaper batteries off of amazon or ebay, they will be the same capacity as the standard battery but you will have more

If this is junk think I will just get the 1800 Mugen Power one.

I bought a case for my Xperia play from them and it's seriously the best £2.50 I've spent in a long time. I've tried 4 cases ranging from the obscenely expensive to the acceptably cheap and their case is by far the best. Easy clip on, easy take off (though it wont ever come off by accident) and it feels/looks very nice.
Cannot recommend it enough, especially after seeing all the negative reviews for every other case in existence for the play.
HOWEVER - this was my first experience buying from Ecell and all was well and good. Unfortunately, hundreds other people have had DREADFUL experiences with them, ranging from fake sd cards to tampered/used/busted phones being delivered and even negligence towards contemporary buyer/seller code and morals.
http://fotios.org/node/2173
I suggest you visit that link and consider carefully before purchasing the battery. I too was thinking of buying that battery but was turned off by the comments in that link.
If you do decide to buy it, let me know if it's worth it please!
EDIT: LOL jgregoryj1 beat me to it
E-Cell are a bit hit and miss, had some good and bad experiences with them, Looked at that exact battery for my play but just looks too good to be true in my opinion
Brought a case from them and it arrived in 2 days. Great case for the play too
But then again once brought a Motorola Milestone from them which took 3 weeks to arrive and came all in chinese. So like I said, the companies very hit and miss. So you take the chance with anything you buy with them
Saying that, Unlike some other people, I think the stock battery on the play is bloody marvellous. Really appreciate it after the crappy 1230mAH battery I had in my last phone - the HD7. You were lucky to get half a day out of that.

I agree. I love the battery on mine. I can get a full day using whatever I want on whatever brightness I want, using whatever connection utility i want and still have some left over by the time I get to bed. I use tunein radio on it when I go to sleep so it's plugged in all night anyway!
yeah i actually found this link "http://fotios.org/node/2173" whilst looking for other vendors selling that battery after i saw the posts about it in the battery thread. They seem fine with cheap items and bad with anything +100 dollars from what people are saying on that forum.
I ended up getting the mugen 3600 myself, but i thought id post up the link so people here could make their own informed decisions, if anyone does buy it, please post and let us know how it goes, i think alot of people would be keen for a bigger stock battery at that bargain price(if it works).
seems like a gold phone bomb atm to me though

Nice, and it has an extended cover. I heard I other threads that there wasn't a extended cover. Anyone here tried the e-cell 3600mAh and the cover? Also, is the mAh increase picked up by the phone automatically, or will I have to tweak a build prop?

I have a gt max (?) 3600mah battery and the phone seems to pick up the battery capacity with no problem. Of course, your experience may differ from mine due to differences in batteries.

i have also an 3600mha battery for my r800i and the duration icreased to about 50%.
The extended cover is really nice and fits perfectly. the only problem with the extended cover is, that it squeaks.
The extended cover also improve the gameplay with the xperia play because with the thicker back you can play really good with the gamepad.
Hey guys I just saw a 3500mAh battery for SGS2 on ebay. Is it safe to use such battery? I mean it won't harm the phone, will it? :O
Probably won't harm the phone, no.
I bought a 3500mAh obscurely branded Chinese battery in mid-December. Tried it out for almost two weeks, a bunch of charge/discharge cycles & estimated its real capacity was around 1900mAh. It also used to heat up a lot on recharge (mid-high 40's Celsius, which isn't normal when the phone isn't being used whilst charging).
I took it back, got a refund & bought an original Samsung 2000mAh battery. Hasn't missed a beat, is obviously close to its advertised capacity given I get around 20% more use out of a charge than I do with a 1600mAh battery.
Obviously your mileage may vary if you buy one of these (you might have a better experience than I did), just thought I'd let you know about my experience.

Battery Life
I am still using the 1650 mAh battery (stock) for my S2.
I am really facing some battery issues. Its charging almost all day !
Yes I am using 3G all day and WiFi HotSpot too. But use wifi at home. Thats when I get good battery life. Any better way to conserve some battery ?
Any tips might help

well i an getting with the original battery 24H of usage.
with the 3500mah i am getting 60H of usage... so my 3500 is truly 3500mah!
the language is hebrew.
i use congnition rom 1.51 and siyah kernel.
So, where can I see a trustful review on batteries for SGS2? What is the most extended one?
It's really frustrating that my current stock battery is only enough for 2 hd video view (4-5 hours).
Also, the higher the mAh value the more battery lifetime is, right?
I would really want to buy 3500 mAh, but it costs so little.
And the official Samsung variant that offers the longest lifetime of a battery for SGS2 is this one, maybe Mugen 3500 mAh is the best choice out there?

What is the model name of the battery? Is it being overheated in comparison to stock one?
why should it overheat?
it is lithium ... same same
Yes, it's special lithium from China extracted under full moon and blessed by a thousand virgins
Really now, if it was possible to manufacture a battery having more than double the capacity of the stock battery while taking up the same volume, don't you think the megacorporate Samsung would buy that technology immediately in order to use it themselves ? "Too cheap to be true" is valid even here; most knock-off batteries either are fake ("9999 mAH SUPER EXTRA" sticker over the original rating), or will degrade quickly in time leaving you with a dud.
Since there are already fake electronic components...
... why not fake and cheap batteries too, certainly seems to be a high demand for them.
a. it is not the same volume! in is twice as much as the original.
b. the i9100 has a circuit that allows a slow stable charge rate so i dont think it will damage the battery.
As well as being made of inferior materials, not being subjected to the same QC, not having the fuel gauge chip present in original Samsung batteries, you pretty much get what you pay for.
My advice would be to avoid non-original batteries altogether, and given a 2000mAh original battery will cost around the same as one of these 3000mAh+ batteries with all their problems & poor life, it's a no brainer.
Stick with Samsung batteries.
fuel gauge chip?
i would like to see that chip in an any cellphone battery please.
If you're not aware of/don't know about the fuel gauge chip in original SGS2 batteries, you've probably been living under a rock since the phone was released

I had an anker battery for my sensation when I had that for a while. I never had any problems with it. It was slightly larger than stock (not true in this case) and seemed to be rated accurately in terms of capacity.
Ill give it a try and let you guys know...For $10 with prime shipping why not...
Any procedures for calibration or first time charging needed ?

As far as I know, no, however I just always let it run down and then charged it all the way the first time I used it.
After using the Anker battery for a few days i can say its seems to be a good stock replacement.
Battery life is better than what i had before and the price, fitment is right
Pete
I have bought some anker batteries, they work about on par with OEM, if not a bit better.
Replacement I have is Sprint branded (BSMD71018L(BTREFD710)) and it seems to be on par for rated capacity. Better yet I just got very lucky. Washed the battery and the cell and the charge controller are fine. Battery both works in the phone and charges. Most batteries might be sealed well but those contacts can still turn it into an ugly mess.
