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.

Cheap 3500 mAh battery ebay

Just trying to get some info before I "get what I paid for"

did you try searching first? Theres tons of threads on this battery. I love it and I think its great, I use it every day and it protects the camera lens. defiantly worth the money, forget that sedio ripoff battery unless your rich.

http://cgi.ebay.com/2X-NEW-EXTENDED...217472?pt=PDA_Accessories&hash=item43a16f0940
I got my batteries from this guy. They are amazing for the price, not as good as seido but they do hold a charge. I charge mine on the charger it comes with only after I know they are completely dead. I can tell I get about 30-40% more battery life out of them compared to stock, just make sure you cycle them a bunch once you get them. After a few complete drains and full charges they do pretty well. Well worth the money. for 10 more bucks u can get another battery and charger.

I have 2 of these and 2 Seidios. The Seidio's are much better. (I only paid $50 and $45 (one was used from someone with an Incredible on eBay, really is exactly the same battery tho).
The Seidio's have been tested at batteryboss.org to actually be around 2800mAh, which is still about 90% better than stock battery.
After using the 3500mAh Chinese ones, I get the feeling they are actually more around 2100-2150mAh (just my guess, won't know for sure until batteryboss tests them), which is only about 40% better than stock.

Lots of info on the ebay batteries all around. I have the 3000mah and love it. I can finally go all day without charging my phone. I dont even have to think about my battery any more because no matter what it wont be dead before I'm going to bed at night. It would be nearing dead before around lunch time sometimes.
From what I have read though, is that all of these ebay batteries are just 2600mah batteries with different stickers on them....Either way, it last me longer than what I need it to, so I am very happy with it.

Do the 2700, 3000, 3200, and 3500mAH batteries on eBay all seem to come with the same rear cover and make the Evo equally thick, or are the smaller batteries a little bit thinner than the largest ones and sold with slightly lower-profile covers?

Is there a way to buy these for that price without ebay? I got banned over $10. I looked around the cheapest I could find was $50.

This is what the MAH seems around, on ebay this would prob be 10 bucks but since you got banned this was the cheapest i found. I wonder if anyone has tried using these back covers with the seidio battery. I bought the 3500mah ebay battery they just have a higher mah sticker on them but i will post results after 5 or 6 full discharge cycles.

So far, there are two extended battery backs: the Seidio and the "Chinese". I've not seen any others.

I saw those on Amazon, they have a couple of 3500's for 40+shipping. Ill probably just pick up one of those. Thanks.

With the battery conditioned 3 times so far, I am at 72% as we speak. I have been using moderate use with 3g enabled synce full volume and medium brightness. I have been surfing the web and I have sent out about 50 texts. Made around 5 3 minutes calls. These battery's seem to be worth the money if you don't want to spend 60 dollars. I have 2 of these batteries and 1 of them is really good and the other one is so so. The good one is the one I am using now, I am guessing it is around 2100-2500mah not close to seido bat a LOT cheaper with a better back cover. I will post pics when this thing actually dies. I am at 5 hours of awake time and 18 hours of uptime with 18 hours since unplugged. I am also overclocked to 1.2ghz with a live wallpaper running the whole time . I got mine off ebay from feitong2009. Sorry for the wall of text, I just like to help people out a little.

Yea I need one cause I stream radio over 3g alot at work, I get about 3-4 hours on a charge. If I could get at least 8 or more with a fat batt, I'll be happy.

I believe they are only rated at around 2200mah...
I have one, it's alright, I don't use it... makes the phone too far for what it's worth.

Here is the battery life at the end of the day. I turned on the phone before I went to bed and put it into airplane mode. When I woke up I did moderate use through the whole day. Good enough for me.

The ones from feitong are legit. Ice had mine for about a month and a half and I'm getting about 12-18 hrs on medium to heavy usage

Yeah, I ordered one. For $10 - why not? I'll post back my thoughts after I receive and try it out for a bit.

For those who can't but on ebay, gorillagadget has them for $20 and obostore.com has the Yooboa(sp?) 3500mah battery with ebay back for $30. Yooboa is a well known chinese battery brand.
Swyped from my supercharged Evo!

I wonder how the Yoobao stacks up to the seidio. Prob the same as the 10 dollar battery's.

I imagine it is slightly better than the ebay batteries yet still slightly under the Seidio. There is a very small difference in between them all though. All of these batteries should be within $10 of each other. Its just crazy that the Seidio is so much when it just barely out last the ebay batteries....

I have the yoobao battery with the external charger from the obostore. I get 2 days of moderate to heavy use. The most i have got was 83 hours from light to moderate use. I'm running Freshes rom. Theirs a big difference in the battery life if you use the external charger.

Review - Mugen Power 4500mAh Extended Battery (for HTC Thunderbolt)

I was recently given the opportunity to trial the Mugen Power 4500mAh battery. Ironically, the opportunity came up just was I was planning on flying cross country with my family, so I thought it would be an ideal time to test it out.
First things first, yes, it is big. Large. Huge. Yes, it is not “pretty” by any means and it takes away from the sleekness of the Thunderbolt. That is the only negative thing I can say.
The first day I turned it on at 2:00 AM Pacific time and it was NEVER turned off until 7:04 PM Pacific time. When I shut the phone off, it still had 50% of power left. Yes, you read that right, 50%. If you doubt my usage for the day, it was as follows:
I have four email accounts (one corporate account that uses Touchdown and three personal email addresses) that I monitor constantly. I am a heavy Facebook user as well. I also used Google Navigation to get to the airport (over an hour away from my house) and the same program to get to our destination on the east coast (one hour and 45 minutes away from the airport.). While on the plane I had it in airplane mode. It was used heavily by my children and I for games, etc. throughout the 5 hour flight. I was frankly amazed that it had that much power left after that full day. I NEVER plugged it in once during the trip.
I then switched over to the standard battery during our week on the east coast. I went through TWO standard batteries a day (EASILY) while using navigation, etc. I was lucky to make it through the entire day with those two batteries. There was a part of me that was longing for my “monster” to be put back on!
I used the Mugen battery again for the trip home. Reverse all of the previous information (Navigation, Airplane Mode for 5 ½ hours, MORE games and customization while in flight, etc.) and this time you can add in Mobile Hotspot and WiFi use once I was home. From 3:00 AM Pacific to 9 PM Pacific, I had 44% of the battery left. Again, I never plugged it in once.
Look, it is not pretty. It is big. It is beautiful though if you are on the road, on an airplane, on a long trip and/or are a power user and you don’t want to worry about plugging in, changing batteries, etc. This battery is now going to be readily available whenever I need that extra time or push from my Thunderbolt. Simply put, call it Beauty and the Beast. Check out Mugen Power Batteries on the web for more.

Nice review

post some pics and if its not bigger than the htc extended im down
Found this video
Its Fugly lol

That thing is freaking huge.

that's what she said

Why couldn't they just make the case like the 3500 it just looks stupid that way. That's pretty much the only reason I don't wanna buy it and the $100 price tag. They sell two 3500 and to covers along with a wall charger on eBay. For like $35 that sounds like a lot better deal.

That thing's $100? For $80, you can get a 16Ah (16000mAh) external battery on Amazon. It doesn't decrease the sleekness of the phone and will fit in a cargo pocket (and maybe even a fairly large hip pocket). That way, it still works when you switch phones. It has 5 USB ports, so you can charge lots of stuff. (No, not advertising, just demonstrating realistic specs. I know there are comparable models, this one is just the biggest one I found).

i currently have the HTC 2750mAh extended battery and got a silicone case for it.
if i get that 4500mAh battery, will i be able to use the same silicone case or have to wait yet again for new cases to become available?

That thing would definitely give you the juice you need but, dang! That is just about ugly lol. I mean if you need that much battery it would be perfect though. If you don't want that much bulk there are several other options you could go with. I saw on Amazon where you can get 2 1400 mah batteries and a wall charger for the batteries for $20! All the reviews seemed positive too. Just another option I guess.

if you even click on this thread thats a good indication that a high mAh battery is what you want and need.
hell, i have 4 1500mAh & 1 1600mAh battery that didnt cut it for me. before i knew it, a battery was dying and had to go through the bother of powering down, opening up, replacing, powering back up.... and in no time repeat.
im using an extended right now and plan to never use the slims again. hell, i should sell all of mine.

i doubt there will be a case for this unless Mugen themselves make it. there r cases for the regular extended battery cuz the battery is common n a lot of people have it. i doubt many people would have this huge thing so probably no cases will ever be released unless its by Mugen or a Mugen partner

One thing I always mention when defending my extended battery is the thickness-battery life trade-off and how, at the size of the HTC extended battery, it is worth the bulk for the change in battery life. I don't think i would be able to say the same for this. If I ever had to slap something that big on my Bolt it would have to last a week

Affordable Extended Battery

I got one from an Amazon seller for $12. I think it's 3,700 mah and I easily get a day out of it. However, it's stupid to use something that large and that adds weight and bulk to such a thin and light device. Especially when it's just as inexpensive and easy to simply buy 2 or 3 stock-sized batteries and a wall charger on eBay. I carry 1 or 2 spare batteries in my back pocket and don't even notice they're there. Why wouldn't you do this?

im currently testing this one.
on my 2nd cycle right now with 26% left im at:
21hs up time, 3hrs screen time about 1hr Pandora. been on 4G/3G the whole time with all my radios on but GPS.
it seems like im getting about 30% more life out of this batt vs the OEM. which seems to be getting me over a full day of use with out needing a charge.

MUGEN is a great brand, i know because i own their battery for my G2 and S2, you get what you paid for man. on test i found that the MUGEN outlast the SEIDO by 30-40 min screen on time under hard benching...now this data is of course base on S2 battery.
right now i am testing Hyperion, look for my post, i will give more update soon as i am on my 3rd full charge right now, will bench by the end of the week. I am in talking with MUGEN and Anker to give me a free sample to do a review on their battery,

id agree that "namebrand" batteries tend to yield better results.
in fact i would have personally preferred a Samsung Extended battery. but i cant see spending $100 one a 4000mAh battery from Mugen when a replacement 63Wh batt from Samsung for my M11x is $125.

Just throwing out counterpoints: It can be a hassle to have to shut down, take the phone out of a case (if you have one), swap batteries and put it back together, etc. With an extended, you don't miss a beat. Also, since the phone is thin and light, having a big, heavy battery isn't so bad -- makes it feel about the same as a lot of older phones.
That said, I'm using a stock battery, but have been considering a nice extended battery eventually.

I just don't see how any one can justify carrying extra batteries on a +600$ phone?
I mean the battery life is great already, not shabby by any means. I got 1d 11h with 3 hour screen on time on my Verizon phone this weekend on stock battery. But no call or hotspot like I do during my work day. But a ~2500mAh would probably last me the whole day even on a work day. I'd pay $45 for that with nice cover. (slightly thicker won't be such a bad thing on this phone)
I have few more days before I can return this phone to verizon for full purchase price of 600 bucks. But it's making me think twice about returning it because it's still 2x better than my rooted galaxy nexus.

Carrying extra batteries, at least for me, is zero hassle. They slip into my back left pants pocket and I never even notice they're there. Granted, I can see swapping batteries being somewhat of a hassle for some people but, even if you had an extra step in removing a protective case, how long could it really take? 1 or MAYBE 2 minutes? This phone shuts down quickly and boots up just as fast.

cheapest mophie juice packs! might run out soon!

bestbuy is selling their mophie juice packs for $60! thats $39.99 cheaper than getting it at mophie. The thing is, its only the white ones that they are selling cheap. Maybe no one likes white. But I bought it and it is perfect. here is the link. hit thanks if you like it.

That is a fair price for this type of case/battery

i know, but the price for mophie pack is really expensive.

Why wouldn't you want this. Double your battery life and a case as well. Perfect for trips, just went to NYC from Boston on a bus and this was a lifesaver. 3.5 hour ride each way and full day in the city and had 30% battery left when I got home. Used GPS internet and listened to my Bluetooth headphone each way. If I didn't have this I would have had a dead battery by noon. Love this pack

For 60 bucks you can probably get 10 chinese batteries off of ebay. Besides that....it makes the phone huge! Ill keep mt extra battery packs and external charger......now if I was using a crapple with no external battery...then yeah....this would be great!

I actually just got the mophie today. It adds bulk but almost no height, just thickness and the phone is still very light. The best part is I don't need to turn my phone off then replace a battery or carry a pocket full of batteries on a trip

Used GPS internet and listened to my Bluetooth headphone each way. If I didn't have this I would have had a dead battery by noon. Love this pack

your math doesn't add up. you say you would have had a dead battery by noon.. that would mean you used 2100Mah in, let's assume you uplugged it at 6 am, 6 hours. and then this pack which is only 2300Mah gave you another.. 9-10 hours, plus you had 30% left? your stock battery must be shot.
now, riddle me this: what is the benefit of paying $69 for an extra battery, vs paying 25 dollars for a hyperion 4200 Mah battery, like I did? with an extended battery your phone is smaller than adding the pack, and it is cheaper. plus it is more efficient to use one large battery, than to try to charge one battery from another.
not being a hater... just answer your question. That is why I don't want this: I don't want to pay more for less.

It doubles as a case. Your phone is still exposed, unless you put another case on it, which makes it practically a brick. This does both, but is the size of your extended battery (minus the case).
At any rate, contrary to what you may think, this forum doesn't exist to convince or sell you items. No one really needs to justify themselves to you, and no one is trying to convince you to purchase anything.

Just bought this at best buy yesterday for $59. Had no clue they cost $99 cause they had no sale price or anything on the shelf but after I bought it I looked online and saw it was advertised for $40 off After using it for a day and a half I probably would have paid the $99 if I knew it was this badass. The look and feel of it is just awesome and it makes the phone very comfortable to hold. Yes it doubles the thickness of the phone and ads a little more weight but having the ability to recharge my phone at the flick of a switch is awesome for a heavy user like me. Ive only charged the case one full charge last night and ran my phone down to 4% today then turned the case on and it charged the phone back up to 83% before it was drained but I also used the phone for about an 45 minutes while it was charging back up. All I can say is this is one sick ass case.

Just looked for the juice pack for that price and the best buy app still says $99. Did you buy it open item?

Fired Up From My Uscellular Galaxy S3 and Sent From Planet 4G LTE

I ordered one online about 10 days ago and picked it up at the store. When I bought it the white Mophie was $59 on the web site while the black was $99. The website now shows them both at $99 so it looks like that deal is over.
For what it's worth, I didn't care for the extra length it added under the bottom of the phone or the hard feel of the case, so I returned it. I like the concept but it just didn't work for me. I bought an extra Hyperion standard battery and a dock with a slot to charge an extra battery as well as the phone. I'm running the Hyperion 2200 mah as the main and it lasts all day.

The sale at best buy where I bought mine ended on the 3rd, also I'm in Canada whether that makes a difference or not
