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.

Changing batteries

Okay, so some guy that my co-workers know brought in a bag of cellphone chargers and cellphone batteries. There are 3 batteries that fit perfectly in the MyTouch slide, they're htc branded and I'm wondering if they'll be compatible with the MyTouch. I don't exactly know what to look for to tell if they are or aren't compatible.
Whatever you guys need to know that's on the batteries, just tell me and I'll post it.
Two of the batteries are red, so I'm assuming it's from the Droid Incredible and th third battery may be from an older htc phone because the battery says "htc innovation" whereas the red ones say just "htc" and the MyTouch's is also just "htc"
The 3 batteries are all 1500 mAh 5.55Whr Model: RHOD160
The MyTouch's battery is 1300 MAh 4.81Whr Model: BB00100
So from the information I gave you guys, tell me if it is compatible please

Yes they are compatable I've been using a hero battery for a while now

I believe the G1s battery said "HTC INNOVATION" on it.

I've got this battery too. Bought it on eBay advertised as a Touch Pro 2 battery. I used it for a little until I realized it's too "thick" for the shallow battery space in the Slide. A few hours of charging that battery in my phone and my battery door seemed to warp a little. From that point on, if I used the stock battery, the door would squeak and creak. I don't use the TP2 battery anymore.

Yeah, the batteries are a bit too big, but by a very little amount. I probably won't use the batteries then since I don't really want my batter door turning out like yours . I guess I'm gonna have to go back to conditioning the stock battery again.

Yeah, it's not worth it. I conditioned my stock battery pretty well (completely dead, charged til light turned green, then 2 additional hours, 5 times) and it's getting awesome life. A full day of texting, calls, web browsing, and an hour or two of Pandora at work, with life to spare, no problem.

Warning about fastboot on Evo

Just want to give everybody a heads up about fastboot on the Evo. First I'll give a little background of the things I have done with my phone.
Root & Nand Unlock
Running CM7 Nightly build #26
Custon Splash Screen and Bootloader
Nothing special about it but it was a work in progress..
Now onto the warning.
I had my phone in fastboot mode working on pushing a different Splash Screen to my phone when I realized that I was late for picking my girl up from work. Looking back now this was a dumb idea, but I decided to just leave and pick her up and I would finish when I came back. Meaning that I left my phone plugged into the computer in fastboot mode and I had the command prompt up as I was typing in the code to push the image. When I returned home my phone was off. I also realized that the charging light wasn't on. I tried turning on the screen and nothing. Tried booting into recovery and nothing again. So i decided to unplug it from the computer and plug it straight into the wall hoping that might help. I was wrong. 30 minutes later still no charging light at all. Not even blinking. Not exactly sure what caused the bricking of my Evo. If it was leaving it in the fastboot screen to long, having it plugged into my computer, having the command prompt up or maybe a combination of all of them.
So moral of the story is don't do this lol.

Wow, sorry to hear that. Have you tried removing the battery for a couple minutes? then put back in and plug in to charge?
My sisters phone was absolutely dead and wouldnt come on and no charge light. It took several attempts of pulling the battery, re-inserting it before the charge light came back on. (If im not mistaken the phone does not charge in fast boot, so maybe your battery is super dead like hers)

Yea, I would definitely try a known good battery before letting your Evo RIP. Sometimes li-po batteries get dead to the point that they wont take a charge.

Fantastic call!!!! My girl also has an Evo so I stole her battery and put it in my phone and presto it works just fine. So now I have my battery in her phone on the charger. It has been a little over 2 1/2 and still nothing. So I am thinking that the battery might just be permanently dead. If that's all that happened then I am satisfied. I can handle buying a new battery but I really didn't want to get a new phone. Thanks to both of you guys "elegantia" and "k2buckley". I appreciate your posts

Glad to help, and glad you got it going again! What a relief for you! Yea, these batteries don't like to die completely, despite what some people say. The fact is, lithium polymer/lithium ion batteries don't like to be drained to 0. But at least it's just a bad battery. Check on ebay, I've heard good results about some of the cheap ones on there. And best buy also has a 1750mah battery, that is the same physical size as stock, but has a little more juice (stock is 1500mah). Good luck.

You can pick up a brand new OEM battery off of Amazon for $13. I'd go that route before the 1750 mAh batteries off eBay. The tests I've seen show they actually have less capacity than the stocker.
Also, this may be kind of pseudosciency but try putting the battery in the freezer for a few minutes and then popping it right on a charger.

It's so wierd because my phone was fully charged when I left the house. So unless fastboot drains your battery like "super quick" I am shocked to say the least. I'm willing to try anything with the current battery I have so I might take the advice of "eventer289" and throw it in the freezer and then on the charger. Not sure what I will do yet if I have to purchase another battery but one thing is for sure, my girl is definitely not going to let me keep her battery so whatever I decide I am going to have to do it quick lol. Thanks again for all the advice

Let me know if it works. I've read about the freezer thing to revive lithium ion laptop batteries, so I figure what the hell, give it a shot.

Your battery got to low and that's why it won't charge it, I had the same thing happen to me last week. I just cleaned up my phone using my spare and took it in to sprint with the bad one back in it. They gave me a new one for free.

My girls phone isn't rooted. So I might just take hers in with the battery and do this. Not a bad idea at all. Thanks

Update- Have had battery plugged in for four hours now and nothing. So final conclusion is that the battery is shot!!! Sprint, here I come lmao!!

yes.. take it to sprint.. you have 1 yr warranty..
99% sure they will just give you a new battery. if they have one!

That's wha I'm hopin

The problem is, I think in certain modes - such as fastboot, the charging code isn't present. If you leave the device unattended, it drains and drains, even if plugged in (notice no charge light in recovery mode either, when plugged in). As stated, if the voltage falls too low, it won't accept a charge. There's probably some way of reviving the battery, but why bother. Hopefully the OP learned his lesson.

Lithium chargers have a built in safety that will check for minimum voltage before attempting to charge the battery. The EVO has this safety mechanism built in. The method to bring the battery back is to charge it in a dumb charger until the voltage reaches high enough for the EVO to recognize it as a proper battery and then charge it. I've never had to do this on a mobile battery but have done it a few times on Lithium Polymer packs for R/C planes. Some cheap Chinese chargers don't check voltage before charging. You could try jumping the terminals from a good pack to the dead pack for a few minutes being careful to jump the exact same terminal on both batteries. It's worth a shot. Excessive discharge can ruin the battery life going forward but you won't really know until you try. I would monitor both packs for excessive heat just in case but in all likelihood you'll be fine connecting them for a few minutes to boost the voltage on the dead pack. You can always get a two pack of batteries and an external charger on eBay for around $20.

^^^^ good info.. on why it is not taking a charge

Probably should change the topic now since this has nothing to do with fastboot. Simply having cmd open with stuff typed in it won't do anything to your phone.

Battery Life Doesn't Matter

(Personal opinion here, of course.)
I don't care about battery life. The battery on the Galaxy Nexus is removable. When my phone is dead, I swap out my battery for another one. Two batteries gets me through ANY day, regardless of usage patterns. Batteries are small and fit in men's and women's pockets easily. They fit in glove boxes, desk drawers, etc. They're portable, lightweight, compact, etc. You can take them almost anywhere.
I purchased the Samsung battery charger kit and haven't looked back. Instead of charging my phone and feeling tethered to my charger all day, I use my phone however I want and swap batteries in/out as I need to, and I only charge my phone overnight while sleeping now. The rest of the time, I only charge my batteries through the charging kit.
All these threads on battery calibration, battery life, etc. just seem unwarranted to me. I'm used to toting a charger around with me, so now I just bring my battery kit (usually it sits in my car, not needed) and if my battery dies, I swap in a fresh one and charge the spare with the kit. This way, I can have my phone on me all the time without worry. If I have no nearby electric outlet I can still take along the extra battery and charge both batteries later. I actually have 3 batteries, if I need them (I can't imagine ever using all 3 in a day).
I don't even use the extended battery. Why fatten up my phone, even if only by a little, if I don't need to do so?
This is food for thought, that's all. Does anyone else just use spare batteries and no longer worry (or even obsess, as I used to do with my Thunderbolt) over squeezing out every drop of battery life? To me, life is easier and better this way.
There's a name for the feeling of not being tethered to your charger all day. I call it freedom. It's awesome.

I see where you are coming from.. What do you think of the battery cover? Is it difficult to work with when swapping batteries and will it last with such frequent use? How do you make sure that your spare battery is always ready (I guess you must be in the habit of always putting it on a charger)?

The battery cover is easy to remove. I ordered two spares when I ordered my battery kit (door covers are only $3 each) in case they wear out over time, which I doubt will happen. Many days I don't even swap batteries, as my phone typically lasts 10-12 hours on the regular battery anyway. I do charge my phone in the car (why not? my phone would just sit there otherwise) which is ~30-45 minutes a day, enough for an extra 20% charge mid-day which helps my battery hit the 10+ hour mark. And if it doesn't, I just swap for a new battery.
The spare is always ready because I always keep it in the charger kit so I can grab it when I'm in need. The kit has a light which turns green when the spare battery is charged to 100%. The light is red otherwise. It's quite handy.
At night I plug in both my phone and the charger kit using the Y cable charger that comes with the kit (allows 2 devices to charge simultaneously on one charger). In the morning, I have my phone and spare, both ready to go.
May I also say, I've impressed a few of my iPhone-using friends with my spare charger kit. They always say "I wish I could do that, but I don't have a removable battery." I lol every time (silently to myself...)

I completely agree. That and who is really not near a charger ever all day? Maybe a few but hey that's what changeable batteries is for.
I see nothing wrong with improving what we have with calibration and optimization though...

Lol sounds like you are super jaded from using a thunderbolt.
IMHO your logic is flawed. Why not get good battery life on one or two batteries rather than mediocre battery life on two batteries.
You shouldn't have to carry around two batts just to get usability out of our device. Two batteries is for when you demand extra from your device.
Like when I went to New York I carried two batteries for my BB9700. Not because it was a battery hog but because I was GPSing and texting all day and didn't want to be stranded with a dead battery. I ended up using both batteries several times skipping charging both of them one night.

edit: I get great battery life on this phone btw. I love it and am very happy with its performance.

I do the same thing. Have the extra battery with wall charger and just throw the spare in my pocket if I go anywhere. Like the OP stated I would much rather swap out the battery (if/when needed) and be able to use my phone like I want than worry about trying to conserve it all day.
I haven't had any problems with the battery cover and even if it did I can buy a new one from VZW for $3.25 with my discount ($4.99 retail) so it is a nonissue.
I honestly don't know why so few people do this. And I very rarely even end up using the spare battery, I just like knowing I have it if needed.

Agreed. I read that stuff to be informed, but no longer out of a crazy desire to extend my battery life because I can't live without doing otherwise. It's a nice change.
Again, I'm not saying anyone else has to or should do this. But it makes so much sense to me, and I like to share what works for me to help others who are looking for other options regarding battery life.

I'm a realistic type of guy. What I want from my phone and what I get from my phone are two different things. To believe they are the same is literally delusional, by definition. To complain about X Y or Z company not providing me with what I want is also a bit irrational if I know that, given today's technology's limitations, what I want might be asking a bit too much. We must work with what we have. I have spare batteries. I use them, liberally if I need to, and I don't mind doing so.
I don't expect a 4G phone to last all day while I play WWF, browse the web, text constantly, check and compose emails, take photos, transfer data, and make phone calls. To get 3-4 hours of screen on time on one battery is great (to me).
I think carrying an extra battery is being more responsible on my end for my own admitted usage of the phone, rather than complaining that the battery life "sucks" or hacking my phone to get an extra 20% battery life (although I'm not against this at all - it's just more work overall). Instead of blaming Verizon, Google, and/or Samsung, I'm taking ownership of the fact that I use my phone quite a lot, and I'm fine with carrying an extra battery or two. Instead of blaming others for the battery life of my own phone, I take responsibility for it and I provide my own solution. If anything, I'm speaking of personal responsibility. And in said responsibility I've found freedom from the dreaded phone charger. Again, it's a nice freedom to have.

I agree completely with the OP. A second OEM battery and quality wall dock charger are my second accessory purchase with any of my smart phones. The first being a good case.

Having a 2nd or 3rd (or 4th!) battery and/or a charger around shouldn't be a requirement for using your device throughout the day. Sure if you use your phone hard then you're going to be used to having a charger nearby, but it shouldn't be a req if you're a normal user.
I don't think its unreasonable to expect a normal (12 hours) days use out of a device. FWIW most people are getting that (especially GSM users), and I don't think the battery issues are as widespread as people seem to think. There are "omg batterylife" threads in every new device forum.

I often go a full day without seeing a charger. Sure I could carry one around and hunt for outlets throughout the day, but I don't think that should be a concern. Just want the phone to be reliable.

For what it's worth, I bought an external charger a couple phones back. Just plug in via USB to the phone if it's running low. Really useful when I'm on the train, for example, and I tether wifi for my Xoom. Gets me through the day in a pinch and I don't have to buy a new one with every phone (though I might buy a larger one now given the Galaxy Nexus' bigger battery).
Also, I usually plug the phone in while at my desk and always charge overnight. But I use the hell out of my phone

I have to agree with Martonikaj I'm afraid. Its a phone, just because you CAN swap out the batteries doesn't mean you should HAVE to to get reasonable usage life.
Sent from my Galaxy Nexus using Tapatalk

I disagree with the OP for having 2nd, 3rd batteries in order to use it properly based on user usage pattern.
First, define your usage pattern then try to optimize the battery to support that.
My usage pattern requires to have at least 3 and a half our screen time, and charge the phone once every two days, before I went to sleep (or during the night).
And this phone battery can do that without any problem ...
So, I don't need second battery ... and I am ordering the 2000mAH extended battery for GSM model. Having extra 250mAH is nice, it's a bonus for additional 30 minutes screen time! ... while still having the same look and thin device profile

Hey guys can someone recommend a good place to buy a second battery and charger if needed? Is it worth getting the extended battery and do I need to buy a different back cover if I purchase one? I am in Australia so was thinking eBay might be my best bet? Cheers

I do the same as the OP. I have three batteries that I rotate through. The OEM Samsung battery that came with the phone and two 1900mah batteries that I bought from eBay (which aren't too bad by the way) . I don't ever have to plug in my phone anymore because most of the time I have two fully charged batteries ready to go. I get on average between 12-15 hours on a single charge as it is with pretty good use, so I'm not worried about my phone dying, its just more convenient.

What about if there is going to be an official larger battery for it?

Just bought two off of eBay for $11, bargain. Hopefully they will do the job. Can keep one in the car and one at work, I should never run out of battery

What about if there is going to be an official larger battery for it?

I am pretty sure i saw an official Samsung extended battery 3000mah with battery door cover on eBay for the GSM version . I think it was around $35-$40.

Camera use forcing shut down

This may be a dumb question but it's a new one on me.
I gave my wife my gs3 when I got a gs4 and her battery life is horrible due to all the games, candy crush etc and fb, so I bought her a spare battery, just a cheap one from cell phone shop.net.
With the cheap battery in every time she uses the camera the phone shuts down, I used the phone for a year with wicked sensations rom with no problems at all (wish Dazed would make the rom for the gs4! LOL)
Has anyone else run into this issue? I'm sure it's due to the cheap battery, but you never know.
Thanks in advance

I had nothing but problems when I had a cheap battery, went back to oem battery real quick. FB is a battery and RAM hog. My suggestion to use m.Facebook.com. Doesn't run in the background. Stays signed in until you clean browser cookies. This should make a big difference in battery life. You won't get notifications, but you can set up Facebook sms messaging, which works almost the same.

Bargain Batteries are not always such a Bargain. I would highly suggest staying away from " Bargain Batteries " . I can tell you from experience, it is sometimes more costly. Among the issues I have come across are, Battery not reading correctly. Or not at all. Fluctuations in Battery voltage. Battery causing the device to run hot. The battery becoming unviable after only a short amount of time. Battery causing the Device to Reboot. Battery causing the Device to act erratic, due to unstable Voltage discharge. Battery not charging correctly. Plus even stranger things. These are just some of the issues I have come across on " Bargain Batteries " . In one Drastic case on a friends Device the Battery over heated while charging, and melted the back cover of his Device. Do some research before purchasing an aftermarket battery for your device. Read the reviews. Check the companies reputation, and be informed.

I figured it was a issue with the cheap battery, thanks for the info, I didn't realize it could cause issues that severe! I guess I'll either have to buy her a better battery or show her how to stretch batt life out!

I have a cheap battery that I bought thinking it was a genuine Samsung battery but turned out to be a counterfeit battery. It works ok but does not last quite as long as the original battery. I have found that if I use the camera with flash the phone will reboot if I am under 50% or so on that battery.

Yes I've seen even weirder confirmed battery issues than the ones I listed. Get yourself a New quality battery. Then I would suggest checking out THIS kernel, and the thread HERE to be on your way towards great Battery life.

Have this issue with a cheap battery (OEM died and I'm poor lol). Found it to be the flash for me. If I disable flash I can take pics without the phone dying. No other issues I can find (other than crappy battery life)
