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.

can we see some pics?

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.

(opinion)which should i buy seidio 3500mah or sprint extended battery

I just saw a seidio 3500mah for $43 plus 5.99 shipping about $50 but the sprint extended battery is $49.99 also just want to know ,your opinion which one is my best choice ,who has a sprint extended battery and who has a seidio please help.

Is the Sprint battery 3500mAh? I thought it was less.
I have the seidio battery and have used it the most of the other batteries I have. Its good and last longer than stock as expected. I don't think you will see any real-world difference between 3200 and 3500mAh.
Really you need to decide which back panel you like better. At first first I hated seidio's, but it grew on me and that boxy back plate actually helps me to hold the phone better. Its weird, but how often do you look at the back of the phone??
Funny enough, I'm back to trying out the stock battery....
Edit: Sprint also includes a white back panel with their battery, if that make any difference.

Neither. Those extended batteries are a rip off and they make your phone bulky as hell. Completely defeats the sleek aesthetic of the EVO. Do yourself a favor, buy these batteries. They last a little longer than stock, you get two of them and a dock charger for $17 with free shipping. Just keep a charged spare with you and swap it out when you need to. So much nicer than having to lug a bulky evo around.

Personally, I'd rather not worry about carrying another battery around when I need extra life. A naked phone with the seidio battery is just as thick a regular phone with a medium sized case, probably less bulky. And I don't use cases.
I go through phases. Right now I'm in max power-save mode with stock batteries; waiting for those Chinese batteries to come in. When I fell like OC'ing for performance, I'll switch to the extended and not worry. Totally worth the costs for me. To each their own.

Carrying a spare stock battery is my suggestion.
Why create bulk on such a sleek device
The Evo stock battery is so flat, you can slip it in anywhere.

You do realize some people care more about function rather then looks.

You can have both with a spare
Personally, I don't give up function by carrying a spare. In addition, with the standard battery, the phone slips right into my pocket without any discomfort.
I don't know if the the OP keeps his Evo in his pocket, but this also may be something to consider.

I have two of the Chinese battery they probably give me a few min more than stock,I have tried kernels to make my battery last,but is just not working ,I see guys w extended battery say they get 20+hrs I cam barely make 6w moderate use on stock and Chinese like 6 1/2hrs.....

I don't have a problem with storing the EVO with monster battery in my pocket. For anyone that carries a spare: do you throw battery management out the window? Because I can keep all of the radios on, OC to 1.19GHz, screen brightness way up, live wallpaper, hotspot, etc, and not be concerned about the battery. It is totally worth the thicker form-factor for me and the OP.
OP, either battery should be about the same. The seidio is the only one that has a case that fits. If that doesn't matter, pick the one with the back plate you like the most.
From my EVO when I should probably be doing something else instead.

sprint is 2600mah ... for me it run for 20 hrs with 30% still left, have 2 emails sync every hour and exchange as items arrive, handcent sms, facebook once in a while, phandroid and some other stuff.

Not sure about Sprint's battery, but I personally have the Seidio 3500mAh and I love it! I had a Seidio 3200mAh on my previous Sprint Mogul phone and that **** lasted 4 days of moderate usage while roaming in a different state!
With the Seidio 3500mAh, I use it about 14hrs a day constantly with heavy usage (20% text, 40% internet, 20% talk, 20% games) and usually end up with 40-60% battery life left at the end of the night consistantly (using Myn's RSL5 rom and Netarchy 4.2.3 SBC kernel).
It also helps to use a SBC kernel, at least in my case. Noticed a big difference, but YMMV.
Hope this helps.

+1 to this. Currently I am playing with the 2000mah batteries for the hell of it but nothing beats the extended if you really just want to rock out hard on your evo!
Sent from my Evo while i should be working

I've been using the 3500mh Seidio battery for several months now and I would never go back to the stock battery. It's just so nice to use the phone heavily all day and not have to worry about having enough juice to last a full day. Now that I'm using Roms and setcpu and other programs which improve battery life, this thing lasts forever.
As a side note, I was in the Sprint store just last week comparing the size of the Sprint 2600mh battery to the 3500mh Seidio and they're literally almost identical in size. The seidio is just a tiny smidge thicker. In fact I tried to fit the Sprint backplate over the seidio battery and it almost fit perfectly.
Point is, if you're going to get either one, and they're basically the same size, why not get the one with 35% more capacity? No brainer to me.

Ok ,just pulled the trigger bought the 3500mah for $53 at amazon w 2-6 day ship total was $53 should receive by sat ...u guys think this was a good deal?

That's about how much I paid. Enjoy the new battery.

3500 seidio. I thought the rounded cover of the mugen would be good, but I didn't like it; I felt I was going to drop the phone every time I held it.
But right now I'm trying out the stock size again to see if it works for my daily usage. And I felt like using a case for a while.

I just got my 3500 Seidio battery from Ebay & am having trouble draining the battery. I love having this issue, lol. I went 24hrs without a charge & with heavy usage. Now I have about 9% battery left. The stock battery would have died in 5hrs.

because the seidio is not even close to 3500 and the sprint battery is a lipo, I would go with the sprint for sure. both are way overpriced though.

Hi ive seen various threads on various batteries but im very interested in these 2300mah and 1950mah standard size batteries on ebay. Anyone had any hands on experience of these and if so are they anygood?
A short comparison to the standard sony 1500mah would be great
Not interested in mugen too expensive for me and i already own a 2600 mah cheapy which is great but too big and ugly.
Anyone tried these out?

Look up gtmax 1780mah xperia play battery on amazon. I'd post the link if I could.
Best deal on an extended battery. Significant increase in battery life, fits with the stock battery cover, and its only $5. It's what I have.

I know you don't want to hear about Mugen Power...
But I will tell you anyway that I have a Mugen Power battery and it gives my phone a full 20 hours of battery life. This is 20 hours of playstation emulation, web browsing, GPS and other forms of very intense use.
This battery is worth every single dollar I spent on it. I makes the phone and consequently me 100% independent of car chargers, wall chargers and other such obstructions.
It is very liberating to know that when I walk out that door in the morning, I can depend on this phone for the entire day. Give the mugen power another look.

I purchased this 2600mah battery from batterybay.net and I simply love it. It works so much better the nthe 1950mah battery I got from Ebay earlier this month. I get a day and half on this thing. And I am a heavy user, lots of gaming and internet usage. This thing was $17 with free shipping, but be warned it took mine 3 weeks to get to me. Either way I totally love this battery. I have not had to charge my phone during the day in weeks, I charge it when I got to bed of course. But Ih ave never had the battery less that 60% at the end of the day.
http://www.batterybay.net/Extended-...n-Xperia-Play-p/sony ericsson -cs-er800bl.htm

but youre still missing the point that he wanted a battery without an extra back cover.

I really don't get some of these requests? A lot of people seem to want a battery that's superior to the stock one, but don't want any extra size, any extra weight and want it very very cheap. If this battery existed, don't you think Sony would have put it in the phone already? Why not contact Sony about your battery concerns? I'm not trying to be rude at all, but until battery technology proceeds further, we have to do what we can with what we have. The big Mugen battery (which I have and use) adds about 6 millimeters in thickness and an ounce or two in weight. My old Nokia 6620 was bigger than this bone stock!! The Mugen was bigger at first for sure but now I don't even notice at all. The massive increase in battery life was more than worth it. Until technology grows, you can't have a battery that's thin, small, light, has a huge capacity and is super cheap. Even with a slightly bigger battery, these phones are still smaller than what we were using just a little while ago.

Cheers for all your feedback, i guess these batteries on ebay are to good to be true. I just thought with technology moving on at such a rate and the 2300mah claims there making these might be a new improved type of slim battery and the purpose of this thread was to see what experiences people who have USED these batteries have had, good, bad or ugly. Its not really for people to guess how they perform and type stuff like you only get what u pay for blah blah... I can guess myself, i wanted some hands on info. I already own a big replacement battery which works great but turns my sleek xperia play into something from the 1990s! Not being rude just trying to get this back on track. Ill try one of these slim 2300mah batteries myself soon im just skint at the moment so i was doing some research first. Ive read a few threads before creating this and it does seem theres alot of people with opinions on these cheap batteries but i dont hear much from people who have actually used them.

And it seemed t owork very well for a few days but after that my phone was glitching out constantly. Games were slow and would stutter. I later found out that the battery's output was not consistent. Thus causing issues with the phones performance. I then found the site I bought my current battery from and even though its a beast the increase in battery is totally worth it. I had to give up my otterbox case for this battery and i have qualms with that. ITs too bad you cant get a battery with extra umph in it and keep the same size. IF you do find something liek that remember that the battery will be hotter then normal and the heat will decrease the life of the battery and the length of time it can hold a charge for.

Nice info. That was one of the batteries i was looking at too... Cheers for that

Does the thicker battery case help with gripping the phone while playing? I don't have any problems holding it, but having that extra grip can't hurt.

To be honest I was afraid of the thickbess of the phone with the new battery cover. But I have found that the thickness does not bother me and when I slide open the controlls to play a game the phone due to the added thickness is a lot more comfortable and I have been able to play for longer periods of time then I could have prior to getting this battery.

Well there is of coarse the posibility of using nuclear power fushion for the battery cells i estimate the eqashion of +2#2.0-#+100=0.11111.000 should be enough power to last one light year of battery use. Oh and no extended back cover will be needed.And i recommend that you do not use your phone to the ear for long periods the sars levels might be slightly high due to the power source.Oh sorry i forgot to mention you need to wear a radiation suit at all times when using the phone and last ov all you must have a 3 mile radius evacuation in place when making a phone call (So there will be no one around to make local calls to i guess). That's about it i think hope i never missed anything out and i hope i was of some help.

Nope, and that in a way is the problem for me, i'm constantly expecting something bad to happen but it hasn't and the battery lasts for ages.

Just ordered the exact same one but from the german Ebay site.

Could you try the Otterbox without the battery cover and tell me if it would fit the thicker battery? Perhaps with the rubbery skin cut under the black shell? I can't because I filed off the clips that attach elsewhere. I basically want to buy a second stock battery door and cut a rectangle in it and, if needed, the rubber for the extended battery to extend into the Otterbox Commuter. I wouldn't want to go without the battery door entirely because it wouldn't route the audio correctly and there is also a gap between the camera and flash which water and other contaminates can freely enter.

So I got the battery about 4 days ago and it's great so far! The added thickness is actually quite awesome. Anyone looking to get some great battery life for cheap should pick up one of these bad boys! If you're all about aesthetic and how your phone LOOKS, well that just shouldn't matter haha.

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.

Extended battery for Note 2......

How many people use their phone so much in 1 day that actually need an extended battery for the Note 2?

There were days I wanted one for my original Note. But the Note 2 has held up well. Even my days of heaviest use it's made it through so far with 10% to spare.
I'm not sure I'd want to carry a massive battery for this thing. But if someone came up with a back and battery that addded 500mah and was only say 2mm thicker overall and really didn't change the fit and style I'd probably go for it.

I always wuss out if I get down to 30% and end up recharging. That might be 1 or 2 days a week. Usually hours of gaming is about the only thing that'll kill my battery in a day. But, I really couldnt see the need for an extended battery on this device for everyday use.

Before owning this fantastic phone I started to worry when the battery indicator showed 25-30% charge. Now I smile knowing that I have at least 5 hours heavy use or about 12 hours standby remaining. If you want it to last even longer but still get email updates and social media updates get Easy Data Pro from the market. Its very good. Apart from the ugly widget that is.

It's easy to kill the battery when at a theme park, vacation, etc.. because you're not sitting next to a charger all day. Many suggest an extra battery but if you're on an extended phone call or in the middle of movie/game how do you change the battery without turning the phone off?

I don't really think being at an amusement park has anything to do with it. We're going 24 hours between charges, why would proximity to an ac adapter change things?

Sorry, guess you stare at the ground while your in line or waiting for anything. I haven't seen anyone get 24 hours screen on time but if I'm waiting most of the day somewhere than my screen is gonna be on. If you're next to an AC adapter than you can easily charge your phone right?

The last time I was at Universal Studios we got the express pass. Zero wait, and we completed the entire Harry Potter experience by 930 am. Had very little phone use the entire day, as we got to enjoy the entire park three times over.
Seperately, not a single person has ever said they have reached 24 hours of screen time. I regularly get 6+ hours tho. What we are getting is 24+ hours between charges.

Also, I would recommend an external battery. I personally use a new trent 5500mAh version. That way I can recharge the phone while on a call if ac power isnt available.

I have never been at an amusement park for 24 hours straight.
If you are on your phone 24 hours a day while on vacation, you're doing it wrong
Btw, I got almost 7 1/2 hours screen on time with 25% left... that's more than enough for me. My screenshots are in the thread for battery life.
That being said, I would rather have an extra regular battery and keep the phone thin, than have a thick phone and try to find a good looking case for it.

I'm actually curious about the extended side project for my classic romo. I want to run my romo and my gs2 on one of the 6500mah batteries for the note two. I hope they aren't crap, I'll probably get one after I get paid on the first, but won't be able to actually have anything to compare it to. I may drop it in my note just to see if it works with the bumper actually, but I have never needed to worry about battery charge. I have gone out on off nights with less than 30% battery life and been home hours later before getting a low battery warning.

I'm new to the Note II, actually it's in the mail. I'm a heavy extended battery user on every device I usually own. As the note II is new, I spent a few days looking at power.
My guess is in most cases it should last at least all day even with heavy use. None of us are usually very far from our chargers or spare batteries.
What I did do, is order this one. http://www.ebay.com/itm/390499613512?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 I'll try this one as a primary and keep the stock battery as a backup.
If it's really 3960 or 3100 who knows, but if it is 3960 then it should be more than enough for a full day of about anything.
I also looked at extended batteries requiring new backs. The thinnest one I could find, was 3-4mm at 6500 mah.

It took a lot of reading on all this, got the Motorola 2 amp car charger and so on, but power was an issue I looked at close for the note II.
Power doesn't seem to be issue from everything I have read, but it makes sense to know what power options are out there and if you need a backup battery anyway, get one with 860 more Mah. if you can.

Here's what I found. Looks like you're right, it's 3100.

How they get away with this is crazy, but at least people are catching it sooner than later.

if you are looking for an extended battery I would be patient and wait for powerskin to announce or shoot down if they are gonna make a case for this phone. Those who don't know powerskin is exactly what it sounds like its a case with a battery built into it. They made one for the GS2(TMO) and GS3 with the wild popularity of Note2 and it being on all four carriers it should be a slam dunk. The best part is they don't add much gerth to the other phones...

I ended up getting an 8500mAh battery off of eBay from this seller:
http://www.ebay.com/itm/8500mAh-Ext...-Samsung-N7100-Galaxy-Note-II-2-/170933592938
I've had it for several days now and am really happy with it. At first I was just going to use it as a backup for going on trips and such but now I think I will use it as my main battery. The back it comes with actually has a sort of faux metallic look to it and fits in really well with the phone. It doesn't look at all cheap like some of the other battery doors I looked at on the 6500 mAh ones.
I've had the phone running for nearly for days straight with some heavy use includs hours of calls and gaming until I finally needed to charge it.

Man, how much thicker/heavier does that make the phone? The main reason this phone isn't "too big" is because of its weight and how thin it is.
I got into the habit of using Mophie Juice packs on iPhones back in the day, and did extended batteries with large battery covers on my Nexus One and HTC Blunderbolt, but with most Androids I just pick up a spare battery and keep it in my wallet. They're thin enough to fit that way. With the newer Samsungs, a spare battery has been a waste of money; my Galaxy S3's spare is still in it's shrinkwrap months after purchase.

It's probably about twice as thick in the biggest part and it is a bit heavier, but the battery door is curved and tapers over to the battery part so it's not twice as thick on the whole thing, just the battery part, but it also doesn't abruptly pop out a square, it's tapered. I think it looks decent and not boxy at all.
I was concerned myself before getting it but I don't really mind the extra bulk and weight considering how much more battery life I get out of it.
I don't think I've seen any other phone have an 8500 mAh battery and considering that I personally don't think it adds too much extra bulk. Of course that's a YMMV sort of thing.
I'll see if I can grab another phone and post a picture of it later.

I'm just curious how accurate the capacity is. I have become very dubious that these odd/no name batteries have the capacity they say they do. For almost a third of the price you can get the 6500s as well.

I honestly can't speak to the accuracy of this 8500 mAh vs the 6500 ones being sold since I haven't tested the 6500 ones. I know it sounds trivial, but I do like the look of the 8500's door vs (the pictures) of the ones for the 6500 batteries.
Anyhow, here is a picture of the 8500 battery with the door on.

I see no need for any larger batteries. The stock one gives me well over a day. But to each their own.

Thanks for both of your replies. I agree, that's a fine looking case, and 8500 mAh battery is almost drool-worthy.
