Do yourself a favor guys....

Stop the debacle and concern on whether or not the 1700mah, 1600mah 1500mah blah blah blah batteries are better than stock.. I have a LOT of experience with Li-Po and Li-Ion batteries (cell phones use Li-Ion technology) and I can tell you WITHOUT a doubt that all these knock off companies are full of SH^* trying to say there batteries are of a higher capacity than the stock battery while staying the same size. Although it is possible to cram more mah into the same size package with li-ion batteries it is VERY unlikely to be able to do so with the current technology out right now. Most of these companies rate their mah on a different scale and actually will pull the battery to a lower voltage to justify their claims when it dosent matter because cell phones have a safety feature that has to shut the phone down at the specified voltage to prevent fires. Yes fires, Li-Ion has a fire risk if it is depleted all the way, not the same risk as a Li-Po battery but a risk just the same. HTC has a separate department that deals specifically with batteries and I can assure you they know and use the most up-to-date batteries they can get their hands on for these devices. There is nothing for them to gain by using inferior batteries in our phone. Those that have purchased the seidio 1600 extended battery and claim to have a better life on the phone are under a placebo effect. If you are just purchasing this "Extended" battery as a spare than buy all means go right ahead but dont expect a miraculous two hours extra from it because it is of lesser quality than the stock battery. I have hundreds of dollars in battery testing and logging equipment and If you guys dont believe me i will run some tests on the stock vs. whichever battery you'd like me too and post the data for all to see, but Ive been down this road before with htc phones and have always come up with the same conclusion......The aftermarket "Extended" batteries actually have less mah's than their stock counterparts.
Of course Im not referring to the htc extended battery in this post, its obviously pushing more mah's with its monstrous size, lol.
....just sayin..

Oh' and to elaborate because Ive also read some concerns over the length of time for charging the thunderbolt (which does seem lengthy I will admit).
Since our phone has such a hard time time keeping up with a normal days use I believe what htc has done is given the battery a longer "saturation charge" for the battery to completely charge before it completes the charge cycle.
Li-ion batteries are charged on a 3 cycle charge system and stage two is what is considered the saturation cycle where the battery may sit at a relatively static voltage for a period of time to saturate the cells with current to top off the charge, some cell phones skimp on this step to give the phone a fast charge time which is termed "charge-and-run" and people assume the device has been adequately charged when it has not. For an adequate "FULL" charge without harming the battery or affecting battery life, typically li-ion batteries take approx. 3-4 hours.

So the 3 batteries I got for 12$ on ebay ARE paperweights?

No. The two I bought for $44 are. How much do oem batteries cost?

I wouldnt go that far, I doubt any of the batteries are "paperweights" yet. Im just making the point that the claims of higher capacity are unfounded and the cheap knock-offs are of lesser quality. Also check where the batteries are made. Good quality Li-ion cells come from Japan.
One thing to note with the cheapies is the temp while charging or under heavy use. Get a temp monitor app and compare between the stock and your aftermarket batteries, they will probably run hotter. Unfortunately I dont have any other batteries to test for you guys other than the stock OEM battery otherwise I would. If I pick any up Ill cycle the stock vs. aftermarket and post the data log between the two.
Also I didnt mean the "fire" comment to worry anyone, Li-ion batteries have protection curcuit that will render the battery useless and unserviceable if the cell reaches a voltage of 2.70v or lower which is where the chemistry of li-ion becomes unstable.

I'll ship your one of the two 1700 when I get it if you wanna test it and post results. Just ask that you ship it back after your done.

ha, I bought the same ones you did.
I didn't expect them to be as good as the 1400 mAh battery that comes with the phone. I just wanted to have a spare battery available in case I'm traveling and watching movies or something (on a plane). Even though it says it's 1500 mAh, I expect them to be more around 1200 - 1400 mAh.

I used their results when I purchased the Seido 3500 for my Evo.

I've used Chinese batteries every chance I get. They do work. From an Eris to the Dinc. 3500mah. Never had a problem. Emails and games etc. I bought the extended battery along with the Tbolt. Just don't like the hump on the back. I'm on eBay every night waiting for the Chinese to strike with a extended battery. At least a Better extended back cover. For $10.99 free shipping ill wait 2 weeks for it. F%$% what u heard their cheap batteries work.

If you do I recommend you buy the 1500 MyTouch4G batteries from ChiChi's htcexpress or their store on amazon. They should be the same a the 1700 Thunderbolt batteries and $20 cheaper.

When I get around to ordering up the batteries Ill post a chart like that on a seperate thread for our phone. I have some pretty sophisticated logging equipment. It shows the temp, charge capacity, voltage, mah, cell balance and health in an easy to read graph.
Im not a battery nerd but I used to be into RC helicopters BIG time and when you have a $5000.00 helicopter that can kill someone its just normal practice to have the equipment to check your $800 batteries so they dont fail 80 feet in the air and blow up or decapitate someone, lol

Heres a video of one of my helicopters (Trex 700 electric) , this one uses two 6s 5000mah li-po batteries and each one costs over $300 and they only last 8 minutes before there dead The video isnt of me however, I need a video camera to post mine but the helicopter is identical for the most part.

(speaking from g1, nexus, and g2 experience only)
i've bought extended batteries for phones for less than $15 each all in the 2400 to 3600 mah range. they last 2-3 days with normal use. the oldest one is 3 years old (g1) and still performs like new.
iirc the seller was based in hongkong.
just saying.

the htc extended battery
personally of all the batteries i have tried this is by far the best one until sedio has an 3500mah then i will be getting that i think

Mugen Extended Batteries! Woopie!

Hey everyone! I asked Mugen if they're going to make any extended batteries for the SGS2! Guess what?:
Look at my attachment They said yes!
I've been a big supporter of Mugen, they've made some WONDERFUL batteries for my older devices (blackberries mostly), and I certainly hope to get an OEM sized (20% more powerful) mugen battery in my device.
Will you guys?

3400mAh... though it was quite bulky. What id really like if they would develop a battery which is wider above the battery compartment.

Samsung makes that, as well: http://samsunggalaxysforums.com/sho...ective-case-extended-battery-power-pack-combo
Which I might get as well. It all depends. I'm waiting this week to get mine SGS2, most people say it's OK. While others moan about its horrible battery life. So I'm not sure. I'll test it out and see. Regardless, I will get the mugen one that fits OEM. And if it's too little as well, maybe the case. All I know, is that I'm already in love with the SGS2

If they would be able to make 2500mAh batteries with the same thickness as the original, I would be happy

Well, they can't do that, maybe 1850, 1900 mAh tops.
What I was thinking off was a battery which is a cover at the same time. A bit like the batteries on the nokia 6210 and 6310i of long ago. You could get those from Nokia in the 'small', normal, and 'large' variants.
The SGS2 and battery construction allows for this. I.E. a battery that 'snaps' on and is the same height as the thicker part of the telephone on the bottom. Such a battery if constructed properly should easily be able to hold +/- 4000mAh while adding little to the overal phone thickness.

anything over 30% more power as the same original size i think its worth change anything under that change my vote to from YES to NOOOOOOO WAY.

Easily 4,000? I don't think so. You're talking about the actual battery + a few more mm for the top. Now, the rest of the body will be the same thickness of the same cover, right? Then that'll make it impossible to construct any usable MAH into that! So we'll get around 2,000 mah. Which by my standards is just frikken fantastic! I'd buy that in a second

I would highly recommend all of you to take a look at this page:

The findings are pretty clear; 3rd party batteries _never_ hold up to their supposed mAh-rating.
If there was a way to make a battery of the same size larger capacity why wouldn't Samsung have done it? Battery capacity is a _huge_ selling point for mobiles, Samsung has truckloads of money and huge departements doing R&D. The same can also be said for all the other big manufacturers.
But lo and behold, time and time again some rather small battery making companies release 3rd party batteries that offers upto 30% increase in capacity at the same size as the OEM batteries, it's just amazing!
One thing is oversized batteries giving you some more juice for your phone (not exactly what it says on the box there either...), but never take a 3rd party's word for it if they say they can cram more capacity into a same-size battery than the original. More often than not they have lower capacity than the OEM batteries despite being rated much higher.

Those are awesome news!
I hope they release it soon!
My experience with the 3200mAh extended battery for SGS was excellent!
I wish they released a smaller one of about 2500mAh of capacity for SGS II, that would be astonishing!
Either way I am looking forward!

You obviously never bought or used a geninue Mugen brand battery before then. They're probably the only company that doesn't make ridiculous claims about battery life.
And just because the manufacturer doesn't squeeze more power into their batteries doesn't necessarily mean it can't be done. They do have cost considerations and a profit margin to think about after all.
EDIT: I expect Mugen's OEM size battery to probably be around 1750-1800mah, or about 10% more capacity than the Samsung one.

Just to clarify, it's not always OEM size. It could be a tiny bit larger, but still fits in the OEM slot. That has been the case with all my blackberry batteries. Why my trusty OEM batteries fit comfortably, the mugens still fit well, but are a little bit tighter. So that DOES justify an increase in mAh.
I have also tried non-mugen / seidio and OEM batteries, and those are ALWAYS crap! Capacity usually drops after 2 weeks or even less sometimes. They're horrible. But mugen has always made great batteries (at least in my case) and I would highly recommend them to anyone Seidio ... meh... Not so much! Because they're REALLY over priced haha.

You quoted one sentence and didn't bother to look at the link I posted?
Let me paste it here then (first mAh rating is what they claim, 2nd is actual mAh rating):
TP2 Mugen 1800mAh 1414mAh 79%
TP2 Mugen, exchanged 1800mAh 1256mAh 70%
Hero, Mugen, oversized 3200mAh 2396mAh 75%
And to add some OEM batteries:
TP2 OEM standard issue 1500mAh 1414mAh 94%
Nexus One, OEM 1400mAh 1357mAh 97%
TP2 OEM, new 2150mAh 2150mAh 100%
What tests have you done that proves Mugen's claims are true? Oh really, you didn't do any except anecdotal ones about your own use?
If people want to spend money on batteries with supposed higher capacity, good for them. But us rational people at least won't have to

I had a bad experience with a mugen battery. Bought it, charged it, used it for one time and it crapped out on the second charge. Dead.
Called and emailed for support and they wanted me to send it back, plus tracking, I wasn't going to pay more.
Basically I threw it out. My loss. But I would never by a battery from them again. It looks like cheap stuff of ebay anyways.
Maybe you'll have better luck though.

True, I was feeling a bit lazy yesterday
Interesting link. Yes, my last Mugen experience was anecdotal (Xperia X1), but if my extended battery had really only lasted ~70% of claimed capacity I would've noticed (plus there would be more people complaining in the forums).
Guess they need to tighten their QC then.

I've bought a bunch of 3rd party batteries for my previous phones (Nexus One, Sensation), and have found that they're pretty much all crap and any perceived gains are simply psychological. Actual batteries mAh ratings are often significantly exaggerated on the product labeling, this can easily be determined by peeling off the label and looking for serial and model numbers printed on the metal battery casing. Googleing these numbers brings up product data sheets from manufacturers in China with the actual mAh rating.
I now only buy OEM batteries as I think it's the only way of ensuring your getting what you think you are. Think of it this way, if Samsung could pack more mAh into a specific size, they probably would. The size of a battery is limited by the battery technology, so if you calculate the mAh/gram density of the OEM battery I would use that as a guideline. 3rd party batteries advertising densities higher than that are probably exaggerating the actual capacity.

Jim, completely agree, and have usually found non-OEM batteries to be total crap, however it's possible to find some that aren't. I bought some PowerGen batteries for my Nexus One about a year ago and they've given me performance on par with the OEM battery. I made that purchase based on positive reviews and since they only cost about $10 (IIRC), way cheaper than OEM, it was a good risk and deal. Worked for me. I'm hoping the QCell batteries will be the same, but haven't seen enough positive reviews to know yet...

I don't want to come off as a completely cynic (which I will), but the two people talking about these QCell batteries are named "ckang008" and "awong12." The latter of the two has 3 total posts on XDA, and "ckang" has a handful of posts since registering this past January (55 total) talking up these QCell batteries for all different devices. Again, they could both be very real people, but this thread to me seems like a bit of a hoax.
But if this thread in fact legit, I do agree with Jim and GPSRider as I have similar experiences with OEM vs non-OEM batteries in the past.

Any updates? I've bought 3rd party batteries before, for my HTC Sensation. Something similar, 2x1900mAh + charger, but theose were Anker, and they were pretty good. Lasted longer than the stock one.
I'm considering trying these as I find it very comfortable to have spare batteries and a battery charger.

I can understand your skepticism. I am one hell of skeptical person too. But I do owe these Qcell batteries (I bought a pair with a charger) and have had them for 4/5 months now. No problems absolutely.
Take the 2050mah for granted. They are not any higher than stock. But the build quality is very good at least for me.

I've had great experience with my 2100 vzw extended battery but that's made by Samsung.

Nexus 5 3800 mAh batteries legit?

Are those Nexus 5 batteries at AliExpress with a capacity of 3800mAh legit? They even claim it's the same size as the original batteries.

No, this is fake... Maybe the real capacity will have a 1500mAh... Search original or replacement of good quality, for example. PolarCell: http://www.polarcell.de/english.html

I second that (what bykumza writes), if the manufacturer (LG) could have fitted a real 3800 mAh battery they would have done that. Often the more modest capacity values are more accurate. I can confirm that PolarCell are very good, well worth the money. The Chinese cheapies often dissapoint.

Actually Nexus 5 and G2 are released almost same date. Nexus 5 has 2300 mah battery and G2 has 3000 mah. I bought G2 battery and put it in my Nexus 5. It fits but it needs ~1 mm space which is not a problem for LG to do it! But they did not! That company did not put 3000 mah battery in nexus 5 which could have been the bestseller because of price/performance and put 2300 mah in it so they could sell their ****ing G2s with great battery life. So no they would not have done it even if they could. Today companies do not do so much things that they can, we just can't even imagine. Intel, Nvidia, Qualcomm, Samsung , apple and other mobile companies are good example. Why on earth can't mobile companies like apple put bigger batteries in it's super high price phones? Juts why? Samsung managed to put 3600 mah battery in 5.5 inch phone which is smaller then iphone 6s plus or 7 plus which has ~2900 mah and takes 3 and a half ****ing hours to charge it!!!!

Fitting G2 battery requires some hardware modification, which I frankly don't feel like doing.
I just wonder which battery is better, a PolarCell one (someone recommend in previous post) or OEM one.

Polarcell is reportedly one of the best alternatives and has a slightly higher capacity than the original cost can say that comes out more or less the same as the original.
Here, unfortunately, you have to answer on your own if you want to take a chance and buy a replacement if you prefer a standard solution.

I know saying this probably isn't that helpful, but you'll probably be better of buying a new standard sized battery from a legit company, provided you can find one that hasn't been laying on a shelf for three years already. Most of the cheap (higher capacity) Chinese batteries you'll find on aliexpress will be fakes (or low quality) anyway. It's just highly unlinkely that it's possible to fit a capacity that high in the same package as a 2700Mah battery.
