why not just buy 3 batteries on ebay for 25 bucks total

Because who wants to run around with three batteries in their pockets?

I wouldn't buy from those manufacturers if I were you. Check out batteryboss.org. Some guy evaluated those battery capacity claims and a lot of them are flat out lies.

I have been a Seidio customer for years and have always being very pleased with their extended battery solutions for all my devices. My experience is that they did extend the battery life of my devices significantly. Without a reputable protocol and some raw data I will trust my previous experience over "some guys" who did "some tests".

Sorry to tell you this, but...
http://batteryboss.org/ These guys are testing a variety of aftermarket batteries for their true capacities, and the one you purchased is included n their test. They only got 1100 mAh out of the actual battery, under the name TP2 Andida, new in their chart.
Good thing you only spent ten bucks, though.

No kidding, the TP2 battery fits? That's the EXACT same battery the hero uses!!
Luckily, I bought two of them, and just got a TP2 as my work phone. That means I suppose, that I have four batteries
btw, those batteries probably aren't 2000mA, but they're nearly as good if not a little better than stock, and for ten bucks each, not too bad.
EDIT - Duh, I see you said you got it from the Hero forums.

Seidio hasn't released their 3500 mAh extended battery for the Evo yet. I'm patiently waiting, as I bought that battery for my hero. I went from charging every day, to every other day.

I like what they did with the rear door. I hope they bring out a hard-case to also work with this battery. To keep it then, they could just cut out the back of the case in the middle where the battery extrudes. The rear cover will provide significant protection anyways.

the seidio batteries are awesome but they are worthless if you dont have the extended case that goes with it.. id just wait for the 3500mah for the evo instead of the one for the eris cause your gonna have the case problem

I wish they would add two more mm to the battery and do 4500mah because at that point the little bit of bulk added doesn't really matter.
/b

i wonder how hot that 3500 will get, i'd rather the 1750 and not change the dynamics of the back case.
apparently only a couple of the batteries on batteryboss come close to their rated mah, i wonder what the evo 1500mah will come in as....

what is the biggest mAh you can buy without changing the back cover? I like my EVO thin.

I believe the highest mah you can get while keeping the evo slim is the 1750 by Seidio. But for 40+ dollars I dont think an extra 250 is worth it

I just wish they would make the battery 1-1.5mm thicker and add whatever they can to that... Then we wouldn't have to change the back.
*Here's where I am horrified to find out I am the only one who's battery cover doesn't really fit on the phone*

Id just wait for the charging case thats comming out.

I wonder if the 2150mah OEM for the TP2 will fit into the evo, and I wonder how much the case will have to be extended. It is the only battery that tests at 100%.

Will the 1350 battery for the Eris work on the evo? I know the capacity is smaller, but will it fit and work?

Normal Size Extended Battery Thunderbolt

So i found this NORMAL sized extended battery on ebay. It has 1700mah opposed to the 1400 mah the factory one has. I have the verizon extended battery and it works great but, IT IS HUGE and there are no decent cases. So for $15 bucks i gave it a shot. When i get it ill let you know if the 300mah makes a difference.

If I am not mistaken...there are threads on this battery and some people didn't find that much of a difference....but each phone is different..
I have the extended battery.....I have a silicone skin that I cut to fit the extended batter cover and then I bought a holster for it...works AWESOME

I didn't see a thread for this specific battery. I cut the case also, and it falls off every time i put it in my pocket drives me crazy lol. Something has to give a 2in thick phone doesn't do it for me. Plus that battery is heavy. So lets see how this cheap battery does

There's a thread somewhere about an independent test from "battery man" or something of the like.
He's stated that these batteries are often rated higher than whey they actually are, like 1700 actually being a 14 something. I'll see if I can find it. It was an interesting read.
Here you go.

It's not a 1700 mAh battery. It's a battery with a 1700 mAh sticker on it. With all the complaints about battery life, and the rumors that the TB was delayed while they worked to improve it, HTC would have gone with a higher capacity battery if one were available in a suitable size.
I got a couple of "1500 mAh" batteries and a charger from Hong Kong for $9 from ebay. They seem to work about the same as the OEM, enough to get me through a day (no 4G here, yet).

Some others had purchased these. If you run Battery Monitor Widget, it tells you how many mAh your battery is, it reports the correct 2750 for my extended, but on these 1700's it reported 1350.

I just need to come out and say it. A battery is a battery, you can't get a huge amount more of mah out of a battery that is the same size. There is no amazing battery that can hold 30% more energy and be the same size. You can increase capacity by taking out circuits, thinning the wall, and optimizing space in the battery but you can't make it tons higher. These batteries promoting themselves and so much more charge in the same package are a scam.

I've been posting on threads on these "1700mAh" batteries because I dislike the company that makes these ads. Its false advertising.
The story is that the seller already had "1500mAh" batteries on Amazon for the MyTouch 4G. Then when the TB came out he listed them on Amazon for the TB advertising them as 1500mAh. A week later he raised the price from $35ish to $50ish for 2 batteries and changed the title to state that its a 1700mAh battery.
For a short period of time people purchased this "1700mAh" battery for the TB. When they received it the sticker still stated 1500mAh. Then later people started getting the batteries with the stickers saying "1700mAh"
Summary: False advertising. Do not buy. Exactly the same as the $3-5 eBay batteries, so SAVE YOUR MONEY

No one is being negative. They're just trying to let you know that you're getting scammed. Even if it was actually 1700 mah you'd get what, a extra hour out of it?

i have this battery and i got to say ain't worth it unless you want an extra battery just like the one that comes with the tbolt...

There's a setting where you can change the capacity. My stock battery read 1350 also.
With that said, I bought these 1700 mah batteries and they are worse than stock. I guess it's a decent price for two extra batteries and a charger, but they suck. They dont extend anything.

i have tried this battery, it is the same, if not worse then the OEM battery.

I bought two of these 1700 mah batteries with a charger a few days ago. I only paid about $26 after shipping so we'll see how well they do. I'm not expecting miracles, I just need one to leave at the office and one for home. If my battery dies, I can still use my phone.

you would probably be better off just flashing a kernel/rom that isn't all bloated and is more energy efficient. Ever since flashing the perfect storm rom my battery life was better. Flashed CM7 when the prealpha came out and its even better.

I'm on the Twisted Sense rom with the bamf_4.3b kernel. I have no complaints with the rom or kernel. My battery drain comes from me never putting the phone down.

My extended batteries came in yesterday. I charged them and carried one today. My phone had drained by about 2:00 pm so I popped in one of my new ones. It's 8:30 and I'm at 69%. I wont say that I'm getting fantastic battery life, but it's fair. I did use navigation and I browsed the web a bit. After around 5 pm, I was on wifi so I'm sure that helped. For $26, I don't think I made a bad deal.

[Q] Is there better way to solve extended battery problem?

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.
Sent from my ADR6400L using XDA Premium App

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

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?

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:

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

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.

Cheers.

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

[Q] Slim extended battery?

Hey everybody,
I've tried looking to see if there was a thread about these two batteries before posting but came up with no results. I'm running a stock SGSII (4.0.4) with an Otterbox Defender (downhill skateboarding/military protection). Phone usage includes emails, texting, FB and games.
I'm looking for an extended battery after going through TWO Samsung OEM batteries within 11 months. Both the batteries got the bulge of death. Sprint store techs have run multiple diagnostics and replaced parts but have no idea why this is happening and won't replace my phone.
I came across a 'Galilio' 2500mAh battery as well as a 'Sporting Persistence' 2520 mAh battery while searching around on eBay. I'm staying away from the Andida 2300mAh after reading several stories about how the contacts were misaligned and the battery wasn't really 2300mAh.
I don't want to go with a big, bulky case due to my requirements for protection. I've read about the Mugen 1950mAh batteries being pretty decent, but they're a bit more than I want to spend.
Thoughts? Ideas? Anyone tried either of these?
Thanks!

I got a 2100mah battery that was really just a fake. It does work fine as a spare and it was cheap but its worse life than stock. I suspect those 2500mah you found are fakes too. I tried the andida which had better life than stock but the contact misalignment caused random reboots after a while.
My suggestion is to just buy an external charger and multiple batteries. I just pop an extra battery in my pocket and go about my day then if I burn thru two batteries in one day I still have the third at home.

Anything on the mugen battery? I want to keep my protective Trident case on my phone instead of putting on the cheap back and 3200mah siedo battery where I can't protect my phone... and wish to have increased battery life and I keep having the problem where when I reboot I go from 69% to 19%..... I haven't checked for battery bulge yet

I came across a 'Galilio' 2500mAh battery as well as a 'Sporting Persistence' 2520 mAh battery while searching around on eBay. I'm staying away from the Andida 2300mAh after reading several stories about how the contacts were misaligned and the battery wasn't really 2300mAh.
I don't want to go with a big, bulky case due to my requirements for protection. I've read about the Mugen 1950mAh batteries being pretty decent, but they're a bit more than I want to spend.
Thoughts? Ideas? Anyone tried either of these?
Thanks!

In my search for extended slim batteries I learned many lessons. I kept buying them from eBay until I got to the bottom of the conspiracy.
The batteries I purchased were for my Galaxy S2 and my Galaxy S3.
Lesson #1: If the battery price is too good to be true, it probably is. Case in point, I purchased several great deals on 'Samsung' brand OEM replacement batteries, all were under $10 bucks and all were counterfeits. All lasted only 2/3s of the time compared to the old and well used battery I was trying to replace. Some of these fakes didn't even have the chip inside that communicated with my phone, so as soon as you plugged in the wall charger the phone would immediately cut off, which is bad for your operating system. If the battery doesn't communicate with your phone properly, it's a fake. I went one step further and weighed the stock battery against the replacement battery and the replacement was far lighter, further proving it was a fake.
Lesson #2: High capacity fakes. I decided to try my luck at after market name brand and generic batteries that claimed longer battery life (a higher milliamp hours [mAh] or higher capacity). I ordered them one at a time, each time one came I would weigh it, it would ALWAYS be lighter than the stock battery (the only exception is Mugen). That was my first clue at fraud. Some of these brands communicated perfectly with my phone and charged OK but they were still lighter, telling me they had less lithium and less capacity. I tested each several times (because it takes a few charges to break in a new battery) but they were the same as the others, all would last only 2/3s the time of the worn out stock battery I was trying to replace. In all cases I would return the battery and try a different brand. In the end buying Mugen brand for $40-$45 a battery is the only way to get a quality replacement battery that lasts a long time but fits like the stock battery.
Mugen batteries are the only brand I can find that actually weigh more than stock OEM batteries. Mugen batteries last a long time, just like they claim. Now I only buy Mugen. Save up your money, it is worth the extra cash for the longer life. Would you want to carry replacement batteries around with you and swap them out twice a day or just use one Mugen? I charge my phone once at night and then use it all day long. Even on days with heavy use I still put it on the charger with a charge left.
I've tried most of the names you mentioned and many more. Maybe there are other illegitimate companies other than Mugen, but I wouldn't know, and I've looked. For anyone wanting to continue my search, the key is to research the name brand and see if they have a website that looks illegitimate. Do they sell batteries for other model phones and devices? Do they sell their own brand of battery charger? If not they are fly by night and are selling you a low capacity battery with a short life but have slapped a label on that claims a higher capacity. If you order one WEIGH IT and compare the weight to your OEM battery that came with the phone.

Have you ever tried the Anker brand? I have also read that those are legit. But I will like to hear that from someone that actually runs serious tests on them. Thank you

I've had the anker battery for over a week now. With my normal use I get about 20% more life than my stock non bloated battery

I have the andida and it seems to last about 2 hrs more then the stock one but ever once in awhile when it over heats the phone resets and you lose about 20% battery

Chichitech is legit, 20$ and got a higher capacity, heavier battery for my HTC Evo 3d. I will buy from them again.
Edit not happy with my chi chi tech batteries for sgs2. Loved it for HTC evo v 4g but it seems to be decidedly higher quality than these ones for the sgs2
