Mugen Power Extended batteries!!!

Hey guys i found today these batteries and watched the review of them by droiddog
http://www.droiddog.com/android-blog/2010/05/nexus-one-extended-battery-reviewgiveaway/
and i am very interested in buying one of these. i am currently getting 1-2 days of medium use and i day of full use with my desire and i am excited with more life. Actually the 1600mha seems nice addition without any bulk added (if it adds 5-10 hours) but the 3200mha is VERY usefull for trips or journeys without charger.
Did any of you tried these batteries ???? i heard that seido are not good but since droiddog recommended them i am into this A LOT.
Here are links to their pages:
Mugen Power 3200mah
Mugen Power 1600mah

i doubt anyone has tried the 3200mah in the desire as the battery cover will not fit

I had a Mugen extended battery for my Hero. IIRC it was 200mAh higher capacity than the original battery, so I expected around 10% to 15% better life from it. In practice though, it actually seemed marginally worse than the original HTC battery and certainly no better.
I've since found this site, and it very much mirrors my experience with Mugen batteries.
Regards,
Dave

Hmm, is there no other batteries to use to extend?

if you saw the video they provide a cover that fits with the battery. and i thought that since the reviewer actually tells it DOES make difference i found it an opportunity.,

my bad, i looked at the droiddog link and and not the mugen ones...
i saw "nexus one" and assumed you had linked to the same battery, sorry

Does seem like a good idea to me, review was nice, and i agree with the guy, having that back on would make it feel better in your hand.
But theyl never do a case like the back for the desire will they?
As the n1 bottom bit on the back isnt removable so it makes it easier, where is desire they would have to do a whole new back plate.

Is it true?

These batteries are not scam. I don't know where you get this guys?
I use the one for Desire, they've been reviewed in many places already and this guy from batteryboss is ridiculous in his testing cuz he got those batteries from ebay and thinks it's really Mugen Power. Mugen comes from Hongkong and has only one good reseller. Many batteries like other accessories are scam, so you just need to know where to order them.

I don't know about the 1600 one, but I've owned the Mugen 3200 for over a month now, and it has literally doubled my battery life.
You quickly get used to the extra bulge and weight, and it becomes a non-issue.
I ordered this one:
http://www.mugen-power-batteries.com/catalog/product/view/id/605/

using mugen 3200 since 2 months, almost doubled battery life...
usually unplug phone around 8, i arrive at midnight with around 60% using facebook, bluetooth, music, market, gps, some calls and sms, google reader and browser... data connection always on, wi-fi sometimes...
the only regret is not having a rubber protection case, just the plastic one they give you with battery and backcover...

Just buy a rubber case and cut it to fit the bigger back.
Btw the mugen is good but the back cover is abit fragile. Open and close it too much and the tabs WILL break. Mines currently stuck on with a bit of blutak

Sedio Innocell 3000mAh Extended Life Battery Picture on there site!

http://www.seidioonline.com/product-p/bacy30ssepc-bk.htm
Still say's under development, but man the thing is fugly IMHO. I am defiantly going to get one from ebay, and why only 3000 mah.

http://cgi.ebay.com/3500mAh-Extende...Accessories&hash=item3cb2c4bb14#ht_4129wt_916

I prefer this back the most. Just so it's entirely even.

why only 3000 mah.

From what I've seen, Seidio's "3000 mAH" probably has more real capacity than the eBay "3500 mAH" batteries. Seidio's ratings are a little more conservative than most.
The problem is that the battery life you and I will see is determined by both capacity AND the battery's ability to deal with high loads. A lithium battery can supply more total milliamperes for more hours if you're drawing a tiny load than if you're sucking down power like there's no tomorrow. Two batteries that seem to allow you to draw "3500mAH" when you're drawing 1mA might appear to be very, very different when you jack the load up to 100mA, and one that's nominally smaller might actually last 10-25% longer than the larger battery at the higher load.
Right now, there really isn't any good, objective, tamper-proof and relevant standard for rating batteries. It's kind of like the way cheap amplifiers get rated as "PMPO", and expensive amplifiers get rated as "RMS, at X% THD". Even a single-chip amp can probably output 500 watts of power for a millisecond at 100% THD before the chip melts, but an amp that can output 500 watts at .1% THD all afternoon is going to cost quite a bit more money. What's missing from the battery industry spec is the "load" part of the equation that tells you how much current was being drawn when that rating was determined.
Oh, also... I might be imagining things, but it looks like they might have actually liked my idea of making the top layer of the battery overflow the stock battery's footprint to squeeze in a bit more battery capacity in the same thickness

on sale now... 69.99

This will make the phone .86" thick, compared to the stock .55". I had the sedio 3500mah on my incredible which made it .7" thick and that wasn't a problem. I'd love to see some feedback on just how huge a .86" phone feels in your pocket, the picture makes it look gigantic.

Can't testify to any actual dimensions, but I do know that I saw a guy with a Seidio battery on his EVO and to me, it actually felt better with the extra size and weight from the battery. It didn't make his EVO seem extra bulky or anything like that, and I think that should be the case with this battery for the Epic.
I want to get this battery, but 2 major things are stopping me:
1. The price is $70. Hrm...between the cheaper extended battery options and the cheaper spare batteries, it's hard to justify $70 for the Seidio battery, especially if the other cheaper batteries seem to last long enough.
2. There's no case for the back - this is the more important reason for me...I can get over the cost of the battery if it's worth it, but how do you protect the back of this thing? And if I leave the top half of my case on, then my phone will look extra ugly and ghetto. They need to make a case and/or more rugged battery cover for those of us that don't want to carry our phones fully or half naked.

IMO a real man lets his phone go naked.
Seriously, I've never used a case for any smartphone. Never had a problem either. But I do carry TEP on every device.

To address your issues:
1) The price is $56 with 20% off coupon code "XMAS20" (without the quotes). I think that's very reasonable, especially when you consider the stock battery with charger is $50 from Sprint.
2) Seidio always end up making cases for their extended battery backs. The back to this unit is best looking one I've seen out of the extended batteries thus far, and give it a month or so and I'm sure there'll be a case you can purchase as well. I personally prefer leaving my phone naked
...yes, I did just order one. $56 well spent, I say - but we'll leave the final decision for when I actually get it and put it through proper use.

Please test the battery to figure out the real world mAh from the battery. I am very interested. If its anything like other Seido extended batteries, I expect it to be around 2450 mAh in reality.

Any input?

Well you've sold me...if they come out with a decently priced battery+case combo, then I'll definitely go for the Seidio option. As far as I see, none of the other extended batteries have any case options.

I just ordered the extended battery and the separate battery charger. Thanks for the Coupon Code. As far as Seidio making cases for their extended battery backs, I've found this isn't the case at all. I bought the extended battery for the Treo 800w and also the HTC Hero and they never came out with an Innocase or anything else, for that matter, for either, although they said they would.
Another option that I've used for the Seidio extended battery is www.mobilecity.com. They had the Hero battery for $20 less than Seidioonline. Right now they list the Epic battery for $59, but the Coupon Code beats that price right now. As of today they don't have it in stock yet. http://www.mobilecityonline.com/wireless/store/productdetail.asp?productid=26868

Just add a kickstand and im sold!

Does anyone have the Seidio extended battery? If so could someone post pictures of the thickness? I'm interested in the seidio battery because i don't like just having 1 hump on the battery case like the 2800 extended battery available on ebay. Plus seidio is known to have awesome extended batteries. If the phone is given a horrible thickness i'd totally buy it. Anyone with the 2800 have a hard time texting or using the game gripper for playing roms? Is it comfortable?

Going off a rough measurement its barely thicker then an Epic with a Seidio Innocase on (about the thickness of a quarter).

I have the 2800 one. It is fine for texting. It definitely adds to the weight of the phone. I don't have the game gripper, but I can still play the racing games just fine. Well, I haven't gotten very far in the game, but I chalk that up to my poor gaming skills to begin with.

Are there any facts that show the cheaper 2800-3000 batteries on ebay are not as good seidio's batteries??? I don't wan to buy something cheap that doesn't last very long.

There is not that I know of. Seido might last a few more charge cycles, but the 3500 mAh battery that I bought and tested here:
http://forum.xda-developers.com/showthread.php?t=864638
is the same thickness, has a true mAh rating around 2800-2900 mAh and works perfectly well with the game gripper. You can also buy these batteries for 12 dollars shipped, so even with the Seido coupon you could have 5 of the 3500 mAh batteries for the same price. And the Seido battery isn't going to have 5 times the cycles than the 3500 mAh ones.
Also, this Seido battery will have a real life rating of around 2400 mAh, if its anything like previous Seido extended batteries.

Based off cosmetics do you think it would be more comfortable having the entire case thicker like the seidio battery case? or is the 3500 mah comfortable enough? Also does it feel odd in your pocket? This is a hard decision for me. Maybe its just me but I like buying the good brand because of the name but the cosmetics of the seidio just look nicer to me than the one you have. This is a tough decision. I understand the battery life but now its all up to looks and feel. hmm.

Case for extended battery?

I know that it wasn't available two months ago. Has there been anything new regarding this? Any cases for the phone with extended battery?

prob not, i know for my old Droid 2 there were hardly any cases that supported the moto extended battery (i think 1 did)
Since i still can't tell if samsung actually has an official extended battery they say that supports the charge, i can't see many manufactures making one.

I have the official Samsung extended battery. But for some reason it's not really marketed a whole lot. Go figure.

I actually prefer the heft. Thought the stock slim battery is too light and weak. The extended battery is giving me 18-22 hours of moderate usage.

Yea, I must admit i havent seen a case for it anyplace. not even in china. I hear it fits inside a clip. i tried mine. but it seems to JUST fit. and floppy. prob will fall out

Hyperion now has a silicon skin that fits with their 3500mAh extended battery. The description says it should also fit with most other 3500mAh or 3600 mAh extended batteries.

Thanks. I just installed my new Hyperion extended battery yesterday and it is too slippery I dropped it once already. Out of necessity, I cut out a hole on the standard size case. It's doable, but ugly from the back, which I don't care since I only see the front side anyway. Lol.
I'm more interested in how the front facing buttons would operate and feel with the rubbery cover.
TIA

What brands or Extended Batteries are good?

Anyone who has used an extended battery for our Verizon GS3, what brands are good or what have you had good experiences with? I never messed with an extended battery before. And yes, I do know if they are big it will come with a new back cover for compatibility of the thickness.

I personally haven't used any extended batteries yet, but within the last couple hours a lot of the android news blogs have been posting about genuine samsung brand batteries at 3000mah. Looks like you get an extended case with it that doesn't seem 'that' big.
Still it's 60 bucks though, more than I paid for the phone, haha.
Edit: ugh.. since I'm a new member apparently I can't post links yet, just google: samsung galaxy s3 extended battery
You should see it in the news.

I picked up the Hyperion 4400 of eBay for like 25 and it's amazing. I get around 9 hours screen time the larger back feels much better in my hands. And there customer service is amazing. The back was as little loose so I emailed them and they sent me a brand new back... And battery!
By the way there is a couple really good comparison threads in the accessories section you may want to check out.
If I helped you in some way.... pass on the favor and help the next person!

I picked up the Qcell batteries and a charger for $36 a few months ago on Amazon, now it's just $25 for two batteries and charger..
I've been very pleased with them!

Wife's using the QCell 4200 mAh battery. She loves it. She uses it all day, and has yet to see it go below 60%. And she spends the entire work day in a lower signal area.

Hyperion works great. I got the 4200 with NFC. My cover cracked too and I emailed them and the same day they sent me a new one with no questions asked.

We've had the phones for going on three months now. So about 2.5 months. It's a great battery. Battery cover isn't so hot though. It's the same thickness around the entire cover. So the camera and flash are in these deep holes. Pictures without flash come out ok, but pictures with flash have sort of a pinhole effect where the picture is much brighter around the center, and too dark at the edges. I'm getting her a Seidio back that I've been told will fit. The Seidio back tapers toward the top, so that the camera and flash are not covered at all. I had the same type of back with my old Evo, and it worked perfectly.

I purchased the Anker 4400mAh Extended battery off of Amazon for $20 (it doesn't support NFC though). I have had the phone on for over two days at one point with medium to heavy usage, and it still hasn't reached below 40%. The only downside I didn't consider when purchasing an extended battery was that the cases I had previously bought to cover the phone would not fit of course, so I purchased two additional extended battery cases (which aren't all that great compared to the standard cases). Check out the reviews on that battery, most of them are excellent.

Right now I rock the Seidio Kickstand case and I know they make another case for extended batteries. I've been happy with this cases so I'm a try it out.

Once I get the Seidio back to use on the Qcell battery and verify that it does indeed fit, I am going to pick up the Seidio kickstand case for it. I have the kickstand case that fits the stock battery right now, and it is a great case!

Right on. Seidio does good work. I like the fact that the kick stand cases are soft on the side but hard on the outside. I read the extended battery version is made for the 3,500 mAh battery but my colleague bought the extended back (not the battery, just the back cover + extended case) and he said it fits his other extended batteries that exceeded 4,000 mAh.

Does this type of case exist?

What I need is a charging/extended battery type case with a flip cover (that bit is easy) BUT I need to be able to insert my phone intact with the original battery cover still on. All the ones I have seen so far one has to remove the battery cover before inserting the phone.
Any suggestions please?
Thanks

I believe anker also makes this type of extended battery "case" you're looking for.
Sent from my XT1080 using Tapatalk

Anker requires battery door removal to install. There is a slim batt in the case and a normal sized one included that has extra contacts for the case battery.
Still pretty slick looking. Its Anker, you can't go wrong.

I don't know if I would trust a $20 battery case from China though.
Anyway eBay has a bunch. Whether you can trust them or not is a completely different story.
