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

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.

Vibrant 4G battery-Launch tomorrow?

As you all know by now, the Tmobile Galaxy S 4G (Aka Vibrant 4G) is launching tomorrow (Wednesday 23rd) with a 1650mah battery which fits in our vibrants.
Has anyone managed to locate a seller for the batteries yet? Or backplates for that matter?

I was actually thinking that, i am buying a new battery

As soon as the batteries and battery covers start selling I am definitely getting them ASAP

Anyone seeing anything? I keep checking and I can't find any.

The Galaxy S 4G section is now LIVE! http://forum.xda-developers.com/forumdisplay.php?f=1065

anyone? i'm planning to buy this if this would work on our phones.

I really want the Vibrant 4g battery for mine. I just bought a 3000 Mah and it made my phone too bulky

I can confirm the Samsung S 4G battery is the exact same size as a Vibrants. My Vibrant took a spill and to make a long story short it was replaced with a Galaxy S 4G. The phone is almost identical to the Vibrant besides the Front facing camera and 4G. Back Cover is exactly the same, just a different design/color. Button placement and everything else looks identical. I plan on buying the same cover I had before.

I don't quite understand why everyone is so interested. Isn't the difference between a 1500 and 1650mAh battery quite negligible? That's only about a 10% increase in life.

10% can mean 2+ hours for the average user.

my girlfriend got the Galaxy S 4g yesterday and I talked her into giving me her silver backplate for my Vibrant! ha!.... fits perfectly and looks great....
she wouldnt let me switch the batteries though... dang! ;}

Be careful with the battery. I swapped batteries with my gf from her Fascinate to my Vibrant because I was low on power. It was fine until it came time to recharge the phone. Both phones would show a battery symbol crossed suggesting wrong battery. Don't know if the same thing will happen with the 4G battery, even though it's a perfect fit.

10 percent ain't ****. Stop playin yourselves and get an extended battery. The 3000 mah seidio battery is lovely for me. Since I don't wear skinny jeans, I don't worry about a little extra thickness.

Battery crossed symbol means battery is nearly dead haha...not that the battery doesn't fit.
This battery is the same as the Italian Giorgio Armani phone which launched a month ago. It's battery is also a 1650 and it works great on ANY galaxy S. All Galaxy S batteries are interchangable. Now, would someone post if they find a place to buy these babies from?

best slim extended battery?

So im in the market for a new battery. A higher capacity one but slimline. I do not want a different size battery door. Anybody know of any good ones for a decent price?

Great question. I'm wondering the same thing.

I bought this one. I had to wait a month for it since is came from Hong Kong. I can get ~16 hours running the screen at 80% brightness, texting alot, 3g radio always on, constantly checking email. No complaints other than the time it took to ship.

I was sceptical but the reviews swayed me and I tried these- http://www.amazon.com/gp/product/B003XOUM12
I'm pleasantly surprised, I notice a definite difference in battery life and the wall charger is a bonus. For the price it's hard to beat and delivery was within a week.

Personally I have found these batteries no better than the stock htc red. With juice defender I get fair batt life with either...10-16 hours or so. I do find the wall charger useful as the battery never gets fully charged when charging in the phone.

There are no slim batteries that are better than stock, the only thing to increase your battery is to add a few millimeters oh my god, to your phone and get a 3500 you won't be disappointed, and yes like someone already said, use the search button next time this must be my like 6th time answering this question muskeg let alone if someone else did too, which I feel has happened too

the battery i have is a 2000mAh i checked it over. seems fine to me.

i get 17-22 hours with my best buy platnium battery (seido knock off) tht i bought off ebay.. so i would disagree there are some extended battery tht does work and there are some that doesnt have the right mah...

I have the 2000mah battery and its marginally better than my OEM battery.

The Seidio stock size extended battery sucks. Doesn't even charge past 90% anymore, and I didn't really notice a difference.

[Q] battery

k im thinking about getting an extended battery for my incredible. Should i but the htc extended battery or seido 3150 extended battery. looked at the reviews and the htc had a lot better reviews. Or should i just stick with my battery and try to consume less power?

It depends on you, I personally don't need an extended battery because I charge 3/4 of the way through the day. If you can't do that then I would get the HTC if its cheaper, I have heard some good things about it from friends. The sedio seems to lose charge capacity faster then the HTC ( Max mah charge)
Or you could buy the 3500 sedio, its 10$ on Amazon. I have one coming

I used the Sedio for over a year and lost no unreasonable capacity for any lithium ion battery. I think the problem here is people don't reset their battery stats or just assume its charged when the light flips green when its really not. I wouldn't buy a battery from HTC for a dime after how poorly the stock battery performed in mine.

The 3500 has no issues I'm aware of, the 3150 was what my friends got and after 1 year of usage it only charged to 2100 mah.
Forget I said anything about HTC, just get the 3500 sedio its only 10$
Did something bad happen to your stock battery?

It was never really $10. There was a seller that was selling fake knockoff's for $10, then amazon caught them and they're sending out refunds to people who bought from them and who don't want to keep the knockoff's.
The 3500 packs a hefty load to your phone physically. Depending how heavily you use your phone the 2150mAh from HTC may be the one you're looking for.
I also use NAV heavily throughout the week and with that battery I never had an issue with it dying out.
Although.. right now I'm using the 1900mAh that still fits in the stock cover. I can still notice a different from the 2150 but even the 1900mAh gets me through the day with all my GPS and network usage.
The 1300 is just a wimpy battery, I was constantly in the red nearing the end of the day and sometimes it died on my if I didn't give it a good 15-25 minute charge sometime during the day.

What company makes the 1900mAh? How is your performance given the time youve had it? I'm noticing on my Seido 1750mAh, some random reboots in the past month that I know aren't rom related. I'm thinking of making a switch to a different battery although I don't want a bigger sized battery.

(Q) OEM 1800 Mah vs. 3500 Mah

Im Looking into the Stock OEM Samsung Epic 4G Touch versus any 3500 Mah Battery i already have the Gorilla Gadgets one and its alright but i was wondering if the OEM would last just as long? If not than its not worth it.
I noticed Mugen Power is like a 100$ for a 3500 Mah
Seidio has a 3300 Mah which is 75$
Hyperion has 3500 Mah which is 25$
I noticed when i slide my keyboard out if i let it fully slide out and that spring motion kicks the battery outta place and turns off.

Yup. I had to put a little piece of thin cardboard like a matchbook cover to keep mine tight. You only gain 20% with the 1800 mAH battery but you slim down considerably. I got an OEM from Amazon for $18 shipped.

Speaking of amazon i had ordered a linux book for school and they charged me a dollar to use their prime service? and i had cancelled the order. But i ended up ordering it again because i realized it was good for the price and will receive it tomorrow. but they charged me again for a dollar? and when i went to re order it it said it was an duplicate order but when i checked in my orders there was nothing so there shouldn't been a duplicate seeing how i cancelled it the 1st. time
I don't want to end up with two books and have a payment for both.

i got 3500 and its great no complaints hear year of use and i still get 20-30 hours heavy use out of it 3 day standby

The battery contacts (metal things inside the phone that keep the battery in place) must be screwed up. Sprint replaced my phone with that problem for free, but I have noticed that the store I typically go to is nicer than other stores, so idk if that is just my store.
