New 1000 mAh standard size battery from Mugen

Touch Diamond will be equiped with 1000 mAh battery without sacrificing the shape, size and impression of using extended battery.

That's great, although the capacity isn't that much higher than the original....
Release date?

100 ???
will that really make a real diffrance????

The Mugen webpage tells release date is end of August. There might have not much difference between the OEM 900 mAh with this 1000 mAh, but it is good that Mugen can enhance the battery by this 100 mAh. User can still choose to buy OEM extended battery which has 440 mAh more but has to use another cover with extended size.

you guys say its not that much - but its an 11% increase! which if your battery lasts 24 hours now - this new one will be an extra 2 and a half hours - its up to you guys if its worth it - im considering it!

I'm not too impressed with the lifetime of the Mugen batteries. I've had two in different PDA's and I've experienced short lifetimes.

not as short as the life in my diamond battery!

Seidio say they will have an OEM sized extended battery that will be more along the lines of 1100mah.. That's the one I'm waiting for.

sounds more like it! 22% increase! woo!

I wonder of its lifetime - some of my rechargable 2500 mAh last shorter than those of 2000 mAh running the exact same device after a few usages. Let's hear the experience once you have tried it.

No probs - if they ever release it... They said end of July, so I guess we can expect it any day now.

Well, there is an OEM sized battery on Siedos site now, but it is only 1000 mAh.

In europe the diamond have a 900mAH so 1000mAH doesn't give more. Perhaps 1 or 2 hours in stand by ?

I know - what a shame....

It's a shame the promised capacity hasn't appeared, but the 11% increase will certainly help me. With the original to carry as a spare I doubt I'll have to change often, but atleast I'll have the option.
As far as the HTC delay is concerned, I have a feeling they may surprise us, with an original sized extended capacity. Their theme is 'innovation' afteral, and there have been some interesting developments in Lion batteries recently. They have the punch to make investments in the right place. I'm holding out hope anyway lol.

I found a 1050mAh battery
Hey guys, I just fund this on amazon.de. It looks to be standard size.

There is one little issue with these kind of batteries, they may catch fire if not properly designed and for the phone. I the east you get batteries rated from A to AAA depending on how good they are and the risk. It doesn't happen often but make sure your phone is ventilated (not put on a carpet or covered) while recharging over night

Do you believe what capacity they print on that battery??? I wouldn't unless someone test it. I used to work with Cadex battery analyzer and believe me, there are so many lies on batteries even brand new ones as GP, Energizer, etc. Consider buying it...
You better buy this one for 7USD with worldwide free shipping:

Mugen Power 1800mAh Battery or EVO 4G 1800 mAh Battery?

So, I was thinking of getting an extended battery for my Desire Z and I need some opinions. The batteries I found are:
Mugen Power 1800 mAh
http://www.mugen-power-batteries.co...nded-battery-for-htc-desirez-t-mobile-g2.html
EVO 4G 1800 mAh (2 Batteries)

They're both pretty much the same thing. If you read through the other battery thread you would know... but I don't blame you for not reading it that thread is loooong!
Anyway I'd go with the chichitec ones since there's 2 of them and a wall charger. Seems like a much better deal.

The mugen fits better. it's made for our phones. the evo 4g leaves a slight bulge on the battery door. annoying for the OCD.
i have both, and i prefer the mugen

The one he posted is not an OEM EVO battery. It is made by chichitec for the EVO. And you can peel the wrapper off of it and it'll fit fine with no bulge.

actually it doesn't. i have the chichitec batteries. i took the wrapper off, AND sanded it. and there is still a bulge. its minor, but it's there.

If you use the Chichi's the bulge in the battery door will eventually ruin the battery
door . It bends the hinges because of the stress over time and then if you decide
to go with the OEM or Mugen battery the battery door is loose and doesnt fit right
anymore . The Chichi's are a bad idea for Vision/Z owners because it ruins the phone.
If you dont care about a $500+ device then so be it but I take care of my phones
like theyre my babies . A cheap $30 battery isnt worth ruining an expensive device .

I sanded mine so much there was very little plastic left . The metal casing
is what kept the door from closing fully . And its rigged to have a piece of
paper under the battery to keep it from shorting out on the SD card tray .
The Chichi's are a bad idea . The Mugen 1800 fits correctly with no rigging
and door issues .

Btw, does anyone know the best place where to buy the Mugen 1800mAh from, their website has it for $45.00 plus free shipping, but 15-25 days shipping and a mugen distributor has it for around $53 including shipping and with a 5% off coupon.

I've been running red Chichitech Evo batteries for 2 and half months, no bulg, no warped door over time, no problems. All I did was remove the wrapper, no sanding or cutting needed.

Having purchased the mugen 1800, I've seen a minimal improvement in battery life across multiple roms. I thought an additional 500 mah would have I bigger improvement.
When I say minimal, an additional 2 hours, I got 8 hours from stock and only 10 from mugen. Obviously I'm a heavy user but I expected at least 30% increase for 30% more mah.
I think I may have been better served with the seido 1700.

My thoughts basically. I'm definitely not seeing a 30-40% improvement in battery life!

I was unfortunate to receive a bad Chichi battery I think. The battery kept restarting on me every time I close my keyboard after using it. The battery also would not power on the phone on it's own. I eventually got it running for an hour and it just died. Tried charging it but couldn't get it to work. No way I could exchange the batter after I have taken the wrapper off and clip some of the plastic off to make it fit. I don't know why people are saying there is no bulge when there especially is one with minor modification.
I would go with a Mugen or Seidio extended battery.

This is turning into a hard decision for me lol, don't know which one to get...

If I were you, and I have the extra cash, I'd go for the mugen.
But, if you don't and need to save all the cash you can get, (like me) go for the red chichis. I went for it and my chichis are awesome! the first week it was worse than the stock battery but then after that the performance was phenomenal. I would usually get around 11 hours of battery life with light use. Now I get around 15 hours or more with moderate use.
Today I made about 1 hour and 30 mins worth of phone calls, some facebooking, some xda browsing, little bit of music, one 5 minute youtube vid, and some regular browsing. I'm currently at 42 percent left of battery life and took my phone off the charger a little less than 11 hours ago.
But the thing with the chichis are that sometimes you get the good ones, sometimes you get the bad ones. My 2 cents.

Extended Battery Help

We need to find out if anyone has a battery that is bigger than 1500 mah. It looks like the Optimus 2x uses the same battery so I would hope someone has a 1650 or 1800 mah out there. Let me know if a source is found. It would be nice to have an external wall charger as well.

Or maybe a dock with spare battery charger on the back to at least hold a stock battery to charge

Check on Ebay every few days. I haven't seen one yet but they make it for most phones. The batteries are thicker than the standard ones and it also comes with a different rear cover to accept the thicker battery. It is usually from China and around $15 or so.

Sometimes there are extended batteries made that are the same exact size as the stock one but have a larger capacity. For example, I bought a Seidio extended 1750mAh battery for my Droid X which was the same size as the original battery but had about 250 more mAh to it...it gave me a couple more hours on one charge. Hopefully something similar is made for the G2X!

Maybe a bunch of us should just write to seidio and ask them to start on developing one for us...

That's the nice thing about the Seidio ones. They are a legit company, and they can usually squeeze an extra 150-400 mAh out of the standard size battery. They aren't too terribly expensive, either. I am thinking for now, though, I may have to give one of those ebay ones with the separate battery charger a try....I have had good luck with ebay laptopt batteries, so....it might be worth the $20 for it.
Also, I will start spamming Seidio's twitter. Lol.

Seidio slim extended batteries are usually way lower than what they state. Just run a quick search on here...bottom line, you may as well use the stock battery in most cases.

Actually, they just re-label their inferior batteries with bigger mAh numbers and make a big profit for their efforts.

Agreed. Seidio does make some legit extended batteries, like the 2500 and 3500 mAh one's they put out for the EVO and Droid X, etc... but the ones that are the same size as the stock battery don't hold any extra juice, they take advantage of the loop hole in the rules concerning how companies can label batteries.
Batteries have a range of mAh that they hold. Say the battery in our device has a range of 1300 to 1700 mAh, most companies will use the average and label the battery at 1500 mAh. Seidio on the other hand will label theirs on the high end of the range at 1700 mAh, which is perfectly within their right to do, but is rather deceiving to the consumer.

There is no range. All the OEM batteries I've tested were within 3% of their tagged rating.
Regarding Seidio, there is no explanation as to why their "same size & higher capacity" batteries consistently deliver less power than an OEM battery.
But don't let me stop anyone from buying their snake oil.
Regarding Mugen, that first link shows a disassembled 3000mAh battery that contained 2 1200mAh cells. I call it fraud, plain and simple. They all do it, I've proved it.

i just ended up getting this http://www.amazon.com/gp/product/B000N63AC6 . i have a body glove case and they're a pain to snap off everytime i want to replace my battery while at work. for me, this is much easier.
now if they made a good extended battery with a custom back cover like i had on my g1, i'd get it.

PSA: There is no magic that will cram more maH into an equal sized battery

It is sad, but true. All the ebay, mugen, seidio etc batteries that claim 1800/900/2000/whatever capacity are scams. same size battery = same capacity.
The best bet for additional capacity with the stock backplate is the evo3D stock battery, which is 1.5mm thicker and has a couple hundred more mah.

Well the evo 3d battery is 3.8v and ours is 3.7v so that might mess up your phone.
And my extended battery not only is a tiny bit bigger but it also weighs more and gives me about 15 hrs a day.
If you can get the type of battery efficiency I get on a daily basis with normal usage then maybe I might believe you.
Sent from my HTC Sensation Z710e using XDA App

all phones have built in voltage control circuitry. 0.1v is not going to harm anything.
that is how phones can handle a stock battery going from ~4v to ~3v while it discharges.
3.8v vs 3.7v is just the nominal voltage of the battery. the voltage of the evo3d is higher since it's capacity is higher.

Well, sorry to rain on your PSA but I was running stock battery (and quite happy with the performance of the stock btw), I opted to try the Anker battery. With little to no expectations, I was really looking for an extra battery, so spending 12usd wasn't bad compared to my Seidio extended battery for my N1 that cost double of the Anker.
I was simply expecting stock performance and got a bit more than expected. Is it magic? Who the heck cares, it works!

Yes the Anker battery is a smidge thicker, not much to the naked eye. As posted in another thread, it's slightly heavier as well. And that could account for a bit more capacity.

The Anker battery without a doubt lasts alot longer than the stock battery!

I don't think all these stuff matter as long as user experience/reviews with the batteries prove positive.

Sent from my HTC Sensation Z710e using XDA App

he's absolutely right. theres a very large capacity differential between standard batteries of varying internal composition. easiest reference, test out a lithium ion battery versus a nickel cadmium battery (both come in AA), which are exactly the same size, and tell me theres no more capacity in one than the other.
Electrical capacitance, as we have seen throughout history has nothing to do with size, so the OP is arguing against the progression of physics. 50 years ago, a battery capable of powering a sensation would have been as big as a book, and yet they used that "magic" you were saying didnt exist to "cram more mAH" into a smaller battery.

Size means very little. Internal construction and quality mean everything. I have seen D cell batteries that are really a AA inside a D cell case. Perhaps the HTC battery is built the same? I dont know, nor do I intend to find out.
If you drain the battery at a constant rate (no, not with your phone, but with more accurate equipment), then you can easily figure its capacity. There is no arguing with that...The aftermarket batteries have been found to have MUCH GREATER capacity than the HTC battery. That is confirmed, 100%.

However it may be my ChiChiTec battery permits me to go a whole day without charging whereas the stock did not. That's good enough for me.

you are an idiot.. no offence intended but you havent read any of the threads on here about all the batteries availaible.
QUALITY OF THE CELLS MEANS EVERYTHING!
crap cells wont hold high amounts of energy, they wont hold as stable a voltage under load and wost of all heat up more than a quality cell.
my anker battery does weigh 2g more than the stock battery and is 0.2mm thicker but that amount of extra mass gets me 4-5 hours more use over the stock battery and thats to do with the quality of the cells more than the exta weight and size.
my stock battery heats up a lot and fast under load and causes the whole phone to get stupidly hot. Anker battery DOES NOT do this at all and only the lower part of my phone gets hot.
some cheap batteries are crap, but there are plenty of good ones too.
if you still think same size = same capacity then ask yourself this, why are some batteries worse than the stock one yet still the same size? if some can be worse then some can be better .... Right???
heres a whole website of information about batteries you can disagree with if you like.
http://batteryuniversity.com/

Here is a size comparision between the stock battery (top) and the chichitec (bottom):

You guys are missing the point of the op. This is not about comparing 2 different battery chemistries. We are comparing an OEM Li-ion battery to an after market one.
The only evidence of an aftermarket battery ever being superior ( in the case that they are the same size and weight) has only been via anecdotal perception of the buyer.
If an aftermarket battery is larger/heaver, there's a chance it could out perform the OEM unit, but when tested using capacity measuring test equipment, It will usually test well below the label mAh rating, unlike the OEM cell which is usually within 3% of its labeled mAh rating.
That's not to say these batteries are not a good value for the money, they are. $12 for a replacement battery is a really good value, especially if its at least as good as the OEM unit.
The real snake oil is in the high capacity multi cell batteries, where the manufacturers have been caught (by me) to have intentionally over stated the mAh rating.
If you get better phone life from your 1700-1950mAh aftermarket battery, that's great! But I doubt you're getting more than 80% of the capacity that's stamped on the label.
I have not seen any independent tests of Sensation batteries yet, no less one that shows an after market battery delivering its labeled capacity.
After reading the many positive reviews of the Anker 1900mAh battery, I just ordered one. Lets see how it measures.

Got the 4500mah from Ebay....

It was $10 with free shipping so I thought it was worth a shot... I received it about 2 days ago and I cannot tell the difference between the stock battery..
This sucks!
So yes, obviously I didn't expect it to be 4500 mah for $10 but I thought it will be at least 3200 or 3000. It is not.
I just want to warn others before they buy it and to hear other peoples experiences if there are any.

If you want a decent extended battery, buy the Hyperion.
I have that batt and the matching honeycomb case you can get with it and I love it.
I never have to worry about battery life anymore (even running stuff like iheart radio or Sirius online which both totally kill battery life)
I even like the feel/weight of the phone with it installed. When I bought it, I figured I would only use it occasionally. Now that I am used to using it, I never take it off the phone. The phone with the standard battery and my awesome rock quicksand case feels way too thin to me now (something I never thought I would say)

thanks morton....
I will try to see if I can return this battery.
I looked at amazon for the battery you recommended. I found it but I also found another battery: (I can't post a link)
It's called QCell and it is rated at 4200.
Any thoughts on this one?
The one you recommended is more popular but this one has NFC and it also has much more reviews.

Another thing to consider is the separate cradle battery charger that comes with a 2100 battery. This way there is always a battery on charge for a quick swap.

Weigh it. At the most basic, the amount of active material in a battery determines its overall capacity. A 4500mAh battery should be significantly heavier (roughly double) than the stock battery.

Another vote here for the Hyperion 4000 mAh battery. Very happy with it!!!
:good:

What website is this hyperion battery?

Think I'll wait a bit to see if anyone brings out a slim 2800 to 3300 battery with a matching back.

I find this to be the easiest for me. I hate extra bulk, so I just have multiple standard batteries ready on tap.

I bought mine here, and it is fantastic so far. http://www.tvc-mall.com/details/Sam...tery-Door-Cover-4300mAh-Black-BATY-I9300-02B/
Shipping took roughly 2 weeks I think.
