Mugen 3200mAh battery for TP2 works in EVO

In case you need an extended battery now, I can report success with a Mugen 3200mAh unit that was intended for a Sprint Touch Pro 2. It cost $70 or 80 when I bought it around Christmas time from an eBay vendor (couldn't find it anywhere else online). Turns out the person I got it for had a Touch Pro 1 and this battery was not compatible so it's been sitting around the house ever since. I just popped it into my EVO 4G and it works perfectly as far as I can tell. Boots up normally and is charging as expected. Of course the back plate does not fit over the fat battery so I left that off and replaced the jelly case which stretches over the whole thing well enough.

Hero batteries work also.. a lot of HTC phone's use the same batteries. I have like 4 batteries for my evo lol
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=280492889203&ssPageName=STRK:MEWAX:IT
I bought these a while back.. worked great in my hero and work just as good in my evo. Plus now I have a standalone wall-charger. Took about a week or so to get here since its coming from Hong Kong.. But it was well worth the ~$10 for 2 batteries and a charger..

ok, i stole its soul for you.

well im glad i order mine from seidio since it comes with the back case but this is good info so i can pass my oem battery to my wife for hero hero with weak battery life

Lol. Nice evo . It's the humpback of xda.

that is disgusting! but more power to you hahaha...lets hope seidio lets you buy just the ext battery cover

oh sweet mother of god i would feel all grossed out if i tried to handle my phone and it was all squishy at the parts that aren't touching the battery or the frame...
How's the battery life with the 3200? After doing some battery life tweaks and mods mine seems to almost be sufficent with the stocker, but it can always use some improvement.

If you don't mind sacrificing the case, I would try cutting a rectangle in it that would leave the protruding part of the battery exposed and let the case hug the phone the way its supposed to. If you cut it just right, the batt should stay in place since it looks like it has a bit of an edge for the case to grip on to.

I'M starting think I should just cancel my order for the 3500 battery and get me 2 1500. What do you guys think?

I'm using the battery from my tp2 as a spare, and carry it in the smaller pocket in my jeans,i don't even feel it there sometimes. With battery tweaks and charging it in my car (usually around 30 min at a time), I only have to occasionally change to the 2nd battery. If you are sensitive to bulk, then go for 2 batteries to split the load, otherwise a bigger battery is more convenient.

Given some of the results from BatteryBoss, I'd say that the battery isn't going to perform at a full 3500mAh. It will still be more than an OEM battery, sure, but I couldn't justify doubling the size of the phone to put it in. You might be better off getting another OEM battery, HTC seems to give about 99% of what they say.

if that site batteryboss is accurate then Mugen's batteries are crap. twice the size for 50% more juice. however, some anecdotal evidence to the contrary: after buying the wrong one, i bought another Mugen extended battery that does work for the TP1 and the recipient is very happy with it. reports that the 3200mAh it lasts about twice as long as the OEM battery.
probably smart to just get another HTC 1500mAh. after the latest update battery drain is much less of an issue anyway.

So can I just go in to a sprint store and ask for a hero battery For free?

The batteries + charger that was listed earlier in this thread work GREAT I've been using them for a few days now great freaking deal ($10 shippped)

Anyone know if the Tilt battery here will fit the Evo with a modified case / back plate? http://www.amazon.com/HTC-Extended-Li-Ion-Battery-RHOD170/dp/B002Y24MJ2
I know Seidio makes a modified back plate that looks like it would fit this and according to battery boss this is the gold standard of extended batteries.

Also confirmed, the Mugen 4500mAh battery for Sprint Touch Pro 2 works in the Evo as expected. It's very... thick. About as thick as the Evo with a jelly sleeve on. Put together it's like the Evo has it's own little podium to stand on.
Assuming batteryboss tests are accurate then true capacity is closer to 75% or ~3375mAh. Main purpose for me is a power supply that can run GPS tracking apps like Cardio Trainer all day uninterrupted. Thickness not an issue since the whole package is tucked away in a Camelback.
Got it on eBay, I don't know where else to find them. Mugen is OOS and ridiculously expensive anyway. An alternative would be an external battery pack that supplies power through a USB port, then cable it to Evo.

[BATTERY] NEW 2800mah extended battery out!

Hey all!
I was looking for extended batteries for my Samsung Vibrant and I stumbled accross this awesome battery auction.
Now don't get TOO excited. This is just a $6 off of the final price of the battery. The battery itself is NOT out yet (will be VERY VERY soon) so he is just selling a $6 off of the price for $1. I talked with the seller and I got the specs for the battery.
Type: Lithiun-ion Polymer Battery, 3.7V
Size: 10mm thickness (1cm). Original battery is 6mm (0.6cm) thick so this is not TOO much fatter.
Capacity: 2800mah
Retail price (without coupon): $36
PRICE INCLUDES A BLACK BACK DOOR.
It is currently in production in manufacturing and should be out on the market very soon. If you're interested in the $6 coupon off the $36, click here.

Man I cannot wait. This is my only complaint with the vibrant as it stands!

I wonder if the new battery door will make the back flush by eliminating the small hump at the bottom of the phone? I love when Ebay is a source of new products. Who makes the beast?

Not sure on manufacturer yet but should be clear soon enough.

hmm... hard to put money down on an item that you don't even know how it looks like

they really need to post some pics of the item along with how the back sits

+1 on Juice Defender
Here's a screenshot of my battery life in the last 36 hours. I still have 9% remaining, so keep in mind that I can get 2+ hours.

what settings are you using to get that?

Man that app is really kinda confusing to figure out. I mean you can by tinkering, but wow.

Dang man, I installed juice defender and it EFFED my phone! It became so laggy that I couldn't really use it at all it took me a full 15 minutes just to get into the app manager to uninstall it...

Not sure what else you may have done to your phone but I have Juice Defender (Ultimate) on my Vibrant and my Wife's Slide and it works great. Since I get a lot of mail, text, and IM's I still can't go a full day but I am getting about double the battery life I had before I started using it.

Dont know if i would be comfortable with a thicker phone... an extra 5MM or so is rather thick. and i wouldnt be able to put it in my nice case that just came in the mail.
I got a car charger and USB cable for my desk at work and i just charge it as i need it. Mostly since im new to android and always playing with the damn thing is the reason i run low.

Another vote for Juice Defender/Ultimate Juice. On the weekends, my phone lasts over 30 hours with moderate use. During the week at work is somewhat of a different story. Running BT, music, and having to deal with poor service inside (phone constantly going in and out of service), I'm still able to get about 12-14 hours.
Overall a great app though.
As far as a thicker battery.....meh. Would definitely have to see the size difference first. And if it still fit in a case.

I think that battery is BS. It wouldnt fit in the phone.

Besides the weight you'll also have trouble finding a case to hold it.
I'm going the route of constructing a back-up battery using 4 AA rechargeable batteries NiMH (4x 1.2V = 5V, with 2800mAh AAs).
Got one of these with leads, on/off switch and cover. You can also get a squarish holder if you don't like the side-by-side layout.
I'll solder it to a mini USB cable, then use a mini to micro converter so that I can also charge mini USB phones. Parts ~$5 in parts.
If you want a fully assembled 4x AA one you can buy it here and here. They also have 1x AA and 2x AA versions, but I don't know how well those work.
Found this 2400mAh battery for the Vibrant here. Price is $59 and the picture doesn't look like the actual product.

I was thinking about gettin a bigger battery but then i found 2x BATTERY+dock CHARGER FOR SAMSUNG GALAXY S Vibrant # on ebay for 10$ and i thought i could just throw a spare battery in my pocket just in case my phone run out.
But..Are theses batteries as good and reliable as original one or the ones that phone store sell? Have you guys experienced any battery that sell for that low cost?

How about this one?

a) It does make the phone look ridiculous, why buy an 11mm thick cellphone, only to double the thickness?
b) My battery already lasts a day easy with moderate use, maybe you're doing something wrong.

Seidio or someone just needs to come out with a 1750mah battery that fit like stock batt. If they did it for the bb bold they can do it for this phone. By the way has anyone tried or thought about trying that amzer1600mah battery? Not much of a difference but I've been thinking about it...if they ask like 30 or 40 bucks not 60

Oh, the irony.
Look: more battery requires more space, which means more bulk which means a bulge and a custom back cover. No other way around it... simple physics. If you don't want a bulge in your phone, get something like a Zaggsparq to plug into for portable rechargeability.

It seems obvious that someone looking for an extended battery is looking for just that. I want my cordless phone to be cordless and I don't want to have to keep swapping batteries. The Mugen is pretty ugly but it really doesn't make the phone that much thicker (17mm vs 11mm). I really just wish there were cases that fit it.

Galaxy Nexus Extended Battery

Do we have any word on whether the GNex will have an Extended battery option? I know the battery and door are removable, but that's a necessary thing for if I'm going to be using this phone.
The holy grail, of course, would be pics of the phone with an extended battery, but that may not happen until well after release.

Im only looking for hopefully an extended oem battery. If not ill prolly just pick up one or two regular batteries depending on how good or bad it is.

Does this mean your going naked

Extended batteries are going to be an issue with this phone. An NFC issue that is, since the antenna circuit is embedded on the plastic cover. Either Samsung would have to engineer a thicker replacement, or someone like Mugen that makes their extended battery cover doors as close to the original design as possible. Inexpensive third party makes would probably forego the design and manufacturing costs, to produce a cover only, but that would eliminate one of the great new functionalities in ICS.
I am watching closely the developments in this, but for now I am planning to have my chargers within arms reach (car, work, solar)...

The only thing better than an extended battery is an actual case that fits it.

Unless the Galaxy Nexus really takes off (not likely, even with VZW), we probably won't see any advanced type of battery + case combo.
I have to be on the go 20+ hours a day sometimes and I cannot spend all of my time babysitting a phone. As much as I want this thing, without an extended battery and a good case, it just won't fit my needs.

Simple, every night charge the phone and a spare battery in an external charger. At 3 PM when the first battery dies, swap in the other. Unless you don't put the phone down all day, 2 batteries should be enough. If you need a little extra, turn off the lte radio when you can get by on 3g.

way too much work, I usually go with extended batteries so I don't have to worry about it. The added 1/4 or 1/6th of an inch doesn't bother me, but having to replace batteries, waiting for the phone to reboot is just annoying.

Still no word on the extended battery front for the GNex?

Battery and Case Issues
Be very careful if you choose to pre-order a case to have on hand when your Verizon GNex arrives. I've read that the stock back cover of the Verizon phone is slightly different from the GSM phones to accomodate the larger 1850 mAH battery. A few case vendors are noting their cases as not being compatible with the LTE version of the phone, but many are not. Of course, if you're ordering a pouch or other case which doesn't require a precise fit, you're probably fine. But, with any sort of hard case, BUYER BEWARE unless it is specifically noted as being for the Verizon LTE version of the phone.

Samsung made an extended battery + a new cover for the SGSII so they'll probably do the same for the Nexus. I hope they do so because we would have a flat back. I dont like this little bump where the camera or the speaker is.
Sent from my HTC Desire using XDA App

Hey guys, just a quick heads up. I just got my Galaxy Nexus and it boots up very quickly so having two batteries and swapping them during the day wont be too painful. The back cover is a bit of a fiddle to put back on though, feels like it might break after a while as its very thin. Hope that helps!

Everyone has their needs but for my Nexus one I bought a second battery and hardly ever used it, most phones now a days charge USB, and Micro USB at that, almost everyone I know has a micro USB charger, I have several, including one at home one in the car one at work, friends co-workers have them etc, I have mixed them or used Nokia Blackberry Motorola HTC Samsung home and car changers, Bluetooth headset chargers etc all USB micro they all work on any device for me there is no need for an extended battery and if the original one dies within a year I will either have a new phone of just buy a replacement battery.

The phone should have come with that battery as the default option. With less than 15% more battery capacity I would say it is not really worth buying.

but what can you lose? lol

Buy 2 stock batteries and solder them together. Works great.
3500 real mah. I didn't think the 2000 extended batteries would fit under the cover from the Hyperion I had here. I agree though, if I can solder it up in an evening, Samsung certainly could work up something.

hopefully more phones in the future will be like the razr and give us a factory extended battery closer to 3000mah.

Razr maxx when I had it for a week was sick! Hard use all day, charged every other day, seriously insane battery life. If that phone ever gets bootloader unlocked, I would be all over it again.

Have you done this solder thing? Any tips?

if you look at the battery in the phone you can see that there is some space at the top of each terminal, use this space to solder a fine piece of copper wire to a second battery. make sure to solder the batteries in parallel, positive to positive and negative to negative, to retain the same voltage.
i remember taking apart a so called 3500mah battery from ebay and they were just two cheap 1500mah batteries tapped together. Apparently in china 1500X2 is 3500.

Why does everyone want extended batteries? 99% of people have access to a power cord most of the day and just don't need it. Granted, I'm new to the phone, but I really hope I don't need to carry around a huge battery or two. Personally I'd rather charge it more often. Just my own opinion.
