The reason why i bought this battery is because i wanted to end my work shift with at least 20-30 percent(on a single battery) f obattery left to make phone call if needed, extend my phone usage away from a charger and longer web searching and the Andida 2000mAh didn't help at all. The result
OEM Battery 1500mAh: listening to music from 4 to 1am = 10% battery life left
Andida 2000mAh: ran 3 test each time my phone ended up dying around 11:30-12:00 this battery is not 2000mAh it somewhere around 1100-1300 it make an good back up battery but not an good extended battery.
I well be running some more test, like how long it last on 3G compared to the OEM battery but as of now i see theres no need to.
If you need an extra battery this is worth the money, but if you need an extended battery its not.
I got mine about 2 weeks ago. Haven't seen anything Earth-shattering as far as performance under normal use, but I watched a 2 and half hour movie on the device yesterday and it only went down to 50%.

i listen to alot of music etc etc daily when im at work so that when i would be able to see if its really a big change. I always end the night with about 10 percent of battery life.
Not terrible
I'm using a pair of these, with an external charger. I don't see that they provide a lot of advantage over the original HTC 1500Ma battery that came with my TP2, but they are an acceptable substitute.
One thing to keep in mind - I think they are heavier than the stock batteries. They are advertised as LiPoly, but I think they are LiIon.

It's under $10. Even if it's only as good as the stock battery it is well worth the money considering the stock one costs about $40. Even an OEM off eBay is as much as $16.

for an extended battery it not, i was looking for extended battery life without having to switch to another battery but this battery didnt do its job 2000mAh i don't think so its at least 1100-1300 i notice my battery died faster even on normal usage compared to the OEM. I honestly had enough of it :\... about to add some MM to my TP2 and get a bigger battery.

You are using the US T-Mobile version, from what I can see in the pix you posted; the only one available is the Mugen 3200, it runs about $79. I have not considered it because it really makes the back of the phone stick out. And it is expensive.
I buyed an used Touch pro 2. so i dunno how was the OEM battery when it was new. When i replaced with this 2000 mAh it nearly double up the battery life. From my site there is full satisfaction.

Aside from the poor English in your post, there's no way a 2000mAh battery is giving you double the battery life or even close to it. It is only 33% higher capacity than the stock battery.

I usually wouldn't care about the size of my G1 and adding thickness to it for the sake of adding battery life but as of late I gotten a hold of a nice plastic cover for my G1 which also doubles as a neato belt clip (for only 10 bucks... flirtin with them T-Mobile ladies does me good ).
Thus, now adding thickness to my phone in exchange for getting rid of this hard cover/belt clip isn't a option I'm very likely to take up and last I checked up on high capacity batteries it would add sigificant thickness like a 2100mah (or was it 2400 *shrugs*). Was wondering if there's any batteries that doesn't add to overall physical size while giving me better then stock life of just 1100mAh. Thanks!!
I know how you feel, I have a sexy ass neon green hard case for my g1, make it look sick. I had the same problem and tried three different battery retailers online for an extended life battery. The one that I settled on was the Andida: check out this post. You can find the eBay seller most of the people in the thread bought it from, good seller but ships from Hong Kong so shipping takes a while. I'd solidly recommend the Andida, I've had nothing but excellent performance out of it, considerably better than the OEM battery from HTC. Some people had mixed reviews about it, but in my experience, it was an excellent purchase.
I'm also using an Andida battery I bought off of ebay for just under $10, and it works beautifully! It's a 1600mAh battery with the exact same dimensions as the stock 1150mAh battery HTC provides, giving you 40% more battery life between charges without adding any thickness to the phone. It's the highest capacity battery I've found that doesn't require you to get a deeper back cover.
I've been useing the Innocell 1400mAh battery and its worked out quite nicely.
i use the regular battery, and it works for me 2 days, with lots of use and 3g use

Not necessarily lies. Battery life is heavily dependent on your particular rom.
Hero based roms seems to suck battery like no tomorrow.
If you are running a hero based rom, try running the latest Cyanogen rom and post back results.

Old battery is running out of juice. Recently found some 1700mah drea160 g1 battery on ebay. Any one tested them yet?
What happen to the ecell 1500mah battery? couldn't find it anymore.
By the way, I'm looking for a standard battery (fits in original housing), please reply if you have something to share. Thanks
Don't know if its the same battery i bought about half a year ago at ebay germany but i had no luck with it.
It was labeled as 1700 mah battery... now, 7 month later the battery has power for about 6 hours in standby (think about 500mah rest capacity)
Even in the first months the battery had not more power than the original htc 1150mah battery, the standby time was about the same.
I recommend not to buy it... better get one or two cheaper standard capacity batteries

well I just ordered mine off ebay, total came to a lil over 5 bucks.
Im guessing its not gonna pan out, but hopin it'll be at least as good as stock, and if its either of those, im getting my money back and keeping the battery. So tis a win for me no matter what.
I'll do review.

This battery works great for me, have had it a few weeks now, has easily doubled my battery life and standby time is crazy it never has come close to dying while on standby.
The one I received is a little different than the one pictured, my backplate has just the camera recessed and not the whole area around it. So the back is even throughout.

Guys,
I found a 1700mah battery on ebay (restriction on new users stops me from providing the link, but it's from Seller austintexwireless ( 18439 sales))
Do you think it's fake at 1.60$?...
I am looking to buy a bigger battery, but I do not want the extended packs with thick back covers, so would prefer one that fits the original slot.
Any advice?

Here you go http://cell-phones.shop.ebay.com/i....kw=&_osacat=20336&_trksid=p3286.c0.m270.l1313
I ordered three batteries off ebay. Two of them were delivered and I'm waiting for the last one. One of the batteries is 1050 Mah and the other is 1150. They both hold equally with a little edge for the 1150 one. I'm really sceptic that in this thickness the battery could have a larger capacity than the stock one. This is a limitation of the Li-Ion technology. However, both of those batteries are much better than the swollen stock one after 1,5 years of use and do a great job. One more thing. The 1050 one was from HongKong and cost me about $3 and the bigger one was from UK and cost me about 7-8$, but was delivered much much faster. I think that you can't go wrong with a battery for 3-4$ but I recommend getting two batteries and an external charger - it's a must have for power users. That's it.
My ANDIDA 1600mAh battery begins to show its age (used to last at least 1-day of use, sometimes 2-day if use is light, now barely make it over a whole day) after 11-month of use. So I got a new 1700mAh (by SCUD) battery.
I shall report back how it performs after a few days of use...
ANDIDA 1600mAh
SCUD 1700mAh
P.S. They both weigh 24g.
A quick search finds that lithium ion's specific energy density ranges from 150 to 250 W·h/kg. If we take the highest specific energy density, so 24 / 1000 * 250 = 6W·h (WHr). Divide 6W·h by 3.7V * 1000 = 1621mAh.
So it's THEORETICALLY possible that these batteries can contain 1600-1700mAh of juice. Whether they can actually store as much is, well, another matter.
Of course, the above calculations haven't taken into consideration of the weight of the housing and the circuitry so the figures should be a bit off.
P.P.S. I remember the original battery (1150mAh) weighed a few grams more through.

that pictures even says 2500 mah, I wouldn't trust it.
so, after a few days of use, it isn't as good as the andida when it was new. the andida surely lasted me at least 1-day of uses (unless i'm using gps the whole time, which drains the battery in a few short hours). this one, it lasts a day of moderate use but not much left.
i'm hoping that with more uses, it will be more "warmed up" and last longer.
i'll report back if this happens.
Looks like the SCUD can last 1.5 day of use mostly.

I got this as well and it's on its way. I hope to simply rotate them well enough that I get good longevity between the three (the two from this purchase and the OEM one).
i also got them they seem to work just fine
I trust that these batteries will work just as well as the OEM one...in terms of both battery life and overall longevity. Based mostly on the fact it's a US based company.
Unlike those HK ones...that sell for cheaper...but they're lucky to even hold a normal charge for like 3 months. Basically, we get what we pay for...more often than not.
I just ordered this off of Amazon. I figured for the low price it was worth the risk.
I've had them since Note Day #1 (2/17) and they are def worth the money. I just can't say how long they hold a charge, since I haven't kept track yet. My guess is that they don't last quite as long as an oem batt. But they don't seem horrendous and 2 batts and a charger to your door for about $30 is hard to not be happy with.

I had an issue with mine today...
Left a battery on the charger overnight and got up and the light showing it was still charging the next morning....Tried another battery and over 4 hours later, the same thing happened...Put another battery in there, and within an hour (battery wasn't empty), it turned blue letting me know charge was complete (and phone showed 100%).
Got another one in there now and it's been there for about 2 hours, and the light shows it's still charging.
Is there a charger out there that has a display so you can tell what's going on??

The charger this comes with outputs DC4.2V~350mA~±50mA. Using the link to the calculator above, you should expect a 2600mAh battery to fully charge with this charger in about 9 HOURS!!

That charger charges at 550MA(MAX). That should take 5.37 hours at best. Still a far cry from the 1000mA that the stock charger uses.

consider the fact that you should not drain a bettery beyond 25% or you will shorten the life of it because the work to hard and overheat beyond that so your talking about 75% of 5.37 hours = 4.0275 hours and i dont think thats a big issue unless your battery doesnt make it 4 hours and trickle charge is better on a battery??

I was under the impression (maybe mistakenly!!) that for the first few charge cycles of a battery, you wanted to fully discharge and charge it...then after that...you can you can go back to the 75% rule.
At least that's the way it is with Lithium Poly Batteries.

Please Help
I guess this thread is dead?
It would be nice to get an update from those who bought these batteries 8, 10 or 12 months ago... to see how they held up.
I've been researching Hyperion and I've found quite mixed reviews... Several places I found photos (obviously can't be truly verified) of Hyperion batteries with the labels peeled back to reveal the metal shells which appeared to be stamped/marked (presumably by the ORIGINAL manufacturer) with different product ID codes, serial #s, as well as significantly lower mAh ratings than Hyperion's outer sticker.
I'm curious if any of those who started this thread still have their batteries... How have they held up? Are they still good?
Does anyone still have one of these batteries that they're no longer using? Would you be willing to try stripping back the label to check to see what you find under it...
I do believe that there probably are some companies that actually do make good, less expensive alternatives. But the scammers need to be exposed...
This one:
http://pages.ebay.com/link/?nav=item.view&id=171470554241&alt=web
I get it, it was a long shot, but for ten dollars I figured I'd try. Like I'm sure everyone would assume, this battery does not last as long as stock. I know SOT varies by user, but with the stock LG battery, I consistently got 35 minutes SOT per 10% battery used. With the new battery, it was 26 minutes SOT per 10%battery used.
I followed the instructions of fully discharging until the phone shuts off and then charge to 100% 3 times and still no change.
It's not a bad backup, but it's also not performing like an extra 1000mAh should.
Thanks for your information. I want to buy that battery because 4000mAh but now i will search another alternative for bigger mAh.
Is there any danger in using a third party battery on the phone? I just bought a 3300ma one from NewEgg (hasn't arrived yet).
I'm curious, will larger mAh adversely affect longevity of phone hardware? I mean, is there any chance it could damage phone? For example, if I get 6000mAh battery?
Zero lemon has a battery 7000 mah lasts 4 days works perfectly
I've used it for over a year and I only need to plug in every couple of days with heavy use. Makes the phone slightly bigger but only charging it every 3 or 4 days is so worth it.

Short answer is yes, I would never use a third party battery unless it was by a very well known company like Zerolemon or the like. Plus if you are buying a battery from ebay, amazon or the like and it is not from a well known company the chances are all your getting is a cheap battery with a higher number on it. Bit like my neighbour that has a Porsche 911 s with a turbo badge, just because it has a turbo badge doesn't mean it is one.
I have a really nice rc car charger and when I bought some high end batteries that were 4000mah they actually took a little more than that. I wish a had a few batteries to cycle thru to see what the capacity really was.

anyway, good luck!!
Really interested in seeing the results as well. I have been looking for a slim battery that will last me through the whole day easily.
Yes, I'm also very curious!
When I was looking for spare batteries I've seen this one but I did not trust is because of the big capacity increase...
Let us now how it works out!
My SOT is so bad. I just installed a mod to increase the battery life. Let's hope that works.
Found review for the one OP posted. Does not look that good. There is another one here with so-so review.
AnTuTu Battery Results....
After my second full charge, i ran the AnTuTu Battery Tester, and lets just say it didnt like this battery at all. I will continue to use it for the rest of the week, and see how it performs on a more with my normal day-to-day usage. I will also post another benchmark on the original battery after a full year of usage, and see how it compares to the new one.
LG Battery History....
...this is the screen shot from the Battery Widget, on the Battery History, when the AnTuTu Battery Benchmark was running, so it looks like only getting around 2+ hours....
Don't believe what the knock off batteries say. There's no way they can fit more battery into the same size as the original without dumping millions into R&D to create a new type of battery.
....after a week of usage, buyer beware...lol, you get what you pay for I guess. really just a sub-par battery, and I will now be using as power bank replacement...and continue using the ORIGINAL battery which came with the device...lol, $9 for a power bank ok i guess... Just Buy the Real Stuff people.

Hi, thats not correct. First, the companys dont invest millions in this batterys. We have the same technic in the g4 as it was in the g2.
Second, sure its possible to get more mah in a pack with the same size.
To get more with the same size, the distance between the celles get smaller.
So they bring in more cells in the same size.
But the problem is that 500mah is nothing.
With standard 3000mah we take a number of 3 hours SOT.
If we count simple, we get from 500mah the power for only 30min.
To get the full power of a battery its recommend to make around 5 to 8 full loading phases. In this time the battery is the same or a little less than the original.
Is the loading phase complete, we get like count around 30min more.
If the screen is brighter or you write a sms more then normal the min go down.
So, i would say thats normaly its not measurable but its really more power inside.
I buy alwasy cheap batterys and had never problems. All manufacterer of batterys buy the cells from 3 or 4 big companies. Inside is all the same.
watch out guys!!!!
i have used cheape batteries from ebay amazon ect.......
after 2 batteries my motherboard died !!!! and even befor that my device have said many times battery invailed and wont power on because the contact (piece tgat contact the battery and suply the power) wasn't recaching into the cheap battery
