Mugen 4500mAh Extended Battery for G2X

Look what I found on Mugen's international site. Of course it has a new back cover for the phone because the battery is so chubby. But 4500mAh, dang!

thanks for the link but NO WAY! $100+ is way to rich for my blood...
i just ordered 2 of these. i like the idea plus they are solar and charge all my gadgets on top of my phone. and shipping from china is 22 for dhl but they are worth it and are the size or smaller than our phone! holds almost twice the charge with multiple voltages including 3.7v which is ours.
Total was around $52 after shipping but just sell one or keep the other for twice as much! ill repost this link in thread.

Too expensive and UGLY

Wow, out if my budget.
I could buy 3 external batteries including shipping, for that.

look at the back cover on that thing and then the shape of the batter! what a waste of space!
I am sorry but I get plenty of juice out of my battery, i dont know what i would do with a battery twice the size let alone three times the size of my current one... that **** would last all week without needing a recharge!
honestly for the same price, little bigger and more juice i could just lug around a mini nuclear reactor... where is tony stark when you need him? im trying to hook my phone up with that mini arc reactor bro!

Yeah, that is way too bulky for the size. If they wanted to extend the back of it, why wouldnt they make the battery a sort of P shape that extends further up the back so it doesnt have to bulge as much?
I MIGHT buy a battery that only makes the back case flush with the camera. I already dont like that camera hump on the back, so a battery that only needed to extend that much or a tiny bit more would be perfect. Maybe like a 2500mAh?

Thread cleanup, back on topic please.

My question here is this: Is it completely safe to use this battery?
I'm thinking perhaps in the future I might want to buy one because I deplete my battery extremely fast with constant use. The only thing I'm worried about is if it will hurt my phone in any way.

you know I was thinking this too, but I did watch some reviews on youtube on their other 4500 mah extended batteries for other android phone models. It doesn't look that bad, infact it seems to make the phones look like a tiny miniature powerhouse PCs from the future.
Right now it says their sold out and will get new stock in June, I'm definitley gonna get one. If like the reviews say that some people don't have to charge this extended battery after 3 days of heavy use then I'll be in G2x heaven. Infact, I would bet as LG was in the design proces for the phone that they were shooting for a phone that could last for 3-5 days on one battery charge, but since marketing research thinks consumers will only buy a slim form factor cell phone, they opted to cut corners on performance for cosmetics, which absolutley sucks in my opinion.

just ordered it. Will post a review once I receive it.
I ordered the 4800 one for my atrix as well. I just received that one today. Will try it out when I get home!

Right on, can't wait for the review. Just wanted to ask though, I saw that they were out of stock and that they'd get more in stock and if I ordered on that certain day I looked on the site, I would get it on June 3rd. I looked at the site again and it said if I ordered that day I'd get it on the 10th, now I checked again today and it said if I ordered I'd get it on the 6th. What gives with all the different ship dates?
You also said you just got the 4800 for your Atrix.
When did you order that one and how long did it take for you to recieve it?
How was it shipped out to you, UPS or USPS?
How did you purchase, with credit card or paypal?
How professional are they and quality of the product?
Does the product come with a specific charger?
And how long did your Atrix last on standard battery and how long does the Mugen battery last?
Sorry for the questions, I'm just very interested in this battery and I'm so ready to purchase, just waiting till they get it in stock, before I ordered, although I'm so anxious just to put in the order now and wait for them to ship it out to me on the proposed date a couple weeks later. But is that wise?

Check the forums for an easy to build tester. I tested a few, and stock batteries for g2 and vibrant, none of the extended ones lived up to their claims. They had more capacity, but not what they claimed, and some caused instability. Stock oem tested within 5%. Extended varied wildly, best being about 25% shy of stated. Imo, that's false advertising at best.
I still have the tester set up. Ship me a battery and I'll test it for you if you like. I'll even pay to ship it back to you, but I will post about it here if you do. Personally, I'm not wasting any more money on them for myself.

I ordered it on 5/13 and received it on 5/20

Came via USPS

I used paypal. Had no issues
How professional are they and quality of the product?
The quality of the product is awesome. At least so far. This is my second Mugen battery. I had one for the nexus one as well. worked just fine. The one for the atrix ROCKS right now. On average usage (with stock battery) I would get about 1.5 days. With the Mugen, I hit 3 days with 1 full charge under the same usage pattern
Does the product come with a specific charger?
Nope. Just the battery and the back cover.
And how long did your Atrix last on standard battery and how long does the Mugen battery last?
1.5 days vs. 3 days

By the way, I had a Milestone as well, which also had an extended battery but from Seidio, and that battery i was NOT happy with. Did not add anything in addition to the stock.

The only way to test a battery is using an external load / voltmeter jig. Based on my past experience with Mugen, their 4500mAh battery will test out much lower, my bet is somewhere around 3400mAh. Just enough to make you feel like you got value for your money. Theres no way the average consumer can compare battery life using the phone itself.

Yup you're right. I do not have a voltmeter handy so I'm just relaying my observations.
So far, it's been good (I'm still talking about the Mugen Atrix battery since I haven't reeived the G2x one yet). Far better than the stock battery (not just by a couple of hours but by days) so I'm happy

I'll pay a hundred bucks to get at least 2-3 days on one charge. Anything to get rid of this miserable battery life that makes you feel anxiety when you're away from an outlet, especially if you use the G2x like I do which is on the internet constantly browsing and watching vids and playing vid games.
Although on another note, auto airplane mode does indeed make the phone somewhat viable and stops the drastic bleeding when the phone is not being used, and I also notice that under settings> accounts & sync> background data turned off also helps very much with the horrible battery drain when on standby.
Tmobile has sent me a replacement battery which I had to pay $10 shipping, so I might recieve it on the 3rd of June, I'll hold off on the Mugen 4500 mah and see how the replacement from tmobile goes and play around with the other settings I just mentioned. I just don't like the idea of switching out the batteries each time. Gonna put wear and tear on the battery cover and all, so even though I have an extra battery, I'm still considering the Mugen extended.

I know exactly what you mean! That is the reason I was willing to spend $100+ on a battery because I didn't want to bother carrying extra batteries all the time or swapping them out or worry about charging each one..
I have one, lasts me 3+ days and don't have to swap anything.
Might not be ideal for most people, might be heavy but hey... it's perfect for me

Without a doubt, there is value in having a battery that can last 2 or 3 days. I've purchased large capacity batteries from Mugen and Seidio, and happily used them.
But, for the price paid for these batteries, I also expected to get what was advertised in terms of mAh rating. It irritates me that these companies feel that they can just print whatever inflated rating they want on these batteries and there is no consequence for them.
Heres what I've determined: High quality OEM batteries I've used in the last 4 years all have been around 1500mAh, as that seems to be the sweet spot in terms of size vs capacity for a phone manufacturer. Mugen & Seidio use cheaper cells, typically 1200mAh for the same physical dimensions as the OEM cell. From there, its simple math, 2 cells equals 2400mAh (not the 3000mAh stamped on the sticker. My guess, without even looking at a picture, is that the Mugen 4500mAh battery is a 3 cell unit with a real capacity of 3600mAh.
3600mAh is not a bad setup, I'd throw $100 for it. But I'd still be irritated.

What would be really nice is the manufacturer giving us the option of buying another cell, the stock oem battery with a replacement back that had a charge balance circuit and anything else it would need to be reliable. Known good cells, just an extra one.

"Gold Business Batteries" for the G2/Desire Z Review

My wife and I have both had t-mobile g2's for almost 2 years now. I had wanted to get addition batteries or replacement higher capacity batteries for a while. There were plenty of cheap batteries on ebay that claimed 1500 or 1600 mAh that would theoretically be an upgrade over a stock battery but it would be a relatively small upgrade and might not even really be an upgrade if they didn't actually live up to their advertised capacity so I had been procrastinating doing anything. Two things changed and I finally stopped procrastinating. First we decided we were going to keep our g2's for about another year. Second I noticed a number of Gold Business Batteries showing up on ebay at a relatively cheap price. They claimed a really high 2450mAh which I figured was not realistic but even if it fell well short of that it should still be a good upgrade. You can find them on ebay with a search for Desire Z gold battery. Can't post a link yet =)
Ordering and shipping was pretty much what you'd expect for cheap ebay purchases from china. The description was poor and communication with the seller was in broken English but I had no major issues. I just selected the cheapest seller at the time and I'm not even sure if that seller is still selling the batteries now. Shipping was predictably slow and packaging was minimal but everything arrived undamaged and is working fine.
The batteries seem to be a little tighter fit than the OEM batteries which seems to be a common complaint about these replacement batteries. I suspect that they would fit better if you removed the "gold" label as it seems to be somewhat stiff and thick for a label but I haven't tried that yet.
No surprise but the batteries don't seem to live up to their claimed capacity. I installed a battery monitor app and ran several full cycles on my battery and it came up with a measured capacity of ~1850mAh. I haven't tried to do the same on my wife's battery but it is enough of an improvement over our original OEM batteries that it is easily noticeable and she has commented on it and prefers the new battery. We got a charger with one of the batteries so she could easily swap batteries rather than charging the battery in the phone but she prefers to charge the gold battery and not swap back to the OEM battery unless she has to. My impression is the same. The new battery definitely lasts longer and was a nice improvement.
I no longer have the battery monitor installed (flashed to a CM9 Mod now) but after a couple months of use I subjectively haven't noticed a large drop in performance for the batteries.
Short review-
Good capacity cheap battery that doesn't require a replacement battery cover and I'd recommend them or by another in the future.

THX for your return man

I agree with OP's assessment. Definitely better than stock. I also notice that they get a lot less HOT than stock battery, which often felt like it would burn a hole in my pants. This battery produces no significant heat. Key word is "significant" since it is obviously impossible to produce NO heat. I suspect that the increased capacity compared to stock is due to much less energy lost as heat.

Just ordered a 2680mah one. Will report back when tested. With any luck it'll come before the weekend as my trip to London will be a good test.

On extended batteries...

Hi all, just stopping in for a bit with some information pertaining to extended batteries.
Most, if not all extended batteries made for the Infuse were made when the phone was first introduced over 2.5 years ago. That being said, understand that Li-Ion batteries do have a shelf life not unlike that of alkaline batteries in the sense that their useful life gets shorter over time. Li-ion batteries come from the factory with a full charge in preparation for the perceived storage time, and will usually be sold before the end of their useful life cycle. Most times this is around 3 years.
See where this is going?
If the extended batteries were made when our phone was introduced, and our phone is now around 2.5 years old, AND Li-Ion batteries only have around a 3 year shelf life, what's to say were not being sold junk when we buy an extended battery from an online auction site?
I've had good experiences and bad ones with buying extended batteries online, and most vendors are willing to work with you in the event of a failed battery, but you will notice that less and less of these extended batteries will be offered for sale, and the ones that are will be nearly brand new with a hefty price tag to boot.

My thinking exactly, didn't know if it was legitimate though, and I was only guessing at approximate shelf life so thanks Pox for confirmation! I ordered a new battery just yesterday!
Only 1800 mAh though. I'm only trying to see if it's the infamous power button issue or not that's causing shut downs and I need to rule out a faulty battery (currently running some cheap 1450 mAh $5 battery from cellphoneshop.net, first and last time I get that one) as an issue.
I generally found that every extended beyond 2100 mAh requires a new back, making the phone thicker and therefore incompatible with most cases.

Well, as to prove a point and make me look foolish, the extended battery in my gfs Infuse decided it was time to let out the magic smoke just last night.
It erupted with enough force to crack the screen from the inside (outer screen is undamaged) and got hot enough to melt the sim card to the socket!
I will be taking pictures as I would like to try to get the seller of the battery to either replace or repair the phone. If not I'll be seeking another Infuse...

I don't think it's beyond repair, but to be honest I don't think it's worth the effort.
It does boot with nothing on the screen but a screen to fit this phone is actually more than I can get the phone for.
I was able to boot the phone and extract the over 8gig of pics and various other stuff, now the phone is sitting in waiting for Samsung or the seller of the defective battery to get back to me about a possible replacement.

stratosphere ii oem extended battery?

was checking amazon for extended batts for my new relay and noticed that most/all said they fit both the relay and the i415 stratosphere 2/ii. so i searched for i415 batteries and found an actual samsung 3000mah unit - http://www.amazon.com/gp/aw/d/B00C2ZEU4S/ref=mp_s_a_1_4?qid=1402385505&sr=8-4&pi=SL75
you can see that it's both 3.8v and 3000mah. the watt-hours listed on the flip side are almost double the stock one in my relay. there's another listing that also comes w/ the door for just a few bucks more, or some listings w/ just the door. the door has a verizon logo on it, but i bet a little thinner or nail polish remover would fix that.
for as cheap as it is, i'm willing to try it out. i will get the one w/ the stratosphere door. i'll also be buying one of the generic ones that actually says relay and comes w/ a door, since it looks like the camera opening might be slightly different. will compare fitment and battery life and of course post back here.
unless of course this has already been tried and failed...

sounds like the one i just ordered. it's currently on the slow boat from china so i'll see it end of month if i'm lucky. now that my contract at vzw is officially up, i'll be going to tmo on friday to pick up some sim cards. yes, tmo is offering to pay your ETF, but the catch is you have to buy a phone from them AND trade in your old one. well they wouldn't sell me a relay as part of the deal and my droid4 supposedly has zero tradein value, so i had to wait out my contract. also sucks that i had to buy another sgs3 for my wife - her verizon one would technically work for voice/text with a tmo sim (in theory) but data would be like 2g speeds. no thanks. hopefully i can sell the vzw s3 (and some redundant accessories like otterbox/etc) to make up the difference.
meanwhile i've already rooted the relay and am about to try out liquidsmooth.

well the mpj 5000mah batt died and now i'm not having any luck getting warranty service. earlier this month it got very hot and swelled up to the point that the back cover no longer closes. bought in june, arrived in august (slow bot indeed) and died in early march. just over 7 months.
might try the strat2 batt this time since i dont want to wait another month for one to be shipped from china again.

I just put a Statosphere II battery (the Polar one linked above) in my wife's Relay. Zero issues, and WAY easier than fitting the bigger battery that required shaving down the back (from Nardholio's thread). That battery died after just a few months, so fingers crossed this Stratosphere II battery last longer (or my wife decides she can give up her physical keyboard!).

It's a 2100mAh battery w/NFC that fits in the stock relay back (there's actually some extra room in there).

Ooh that does sound nice. Im beginning to regret ordering another standard OEM one from china. All the good batteries are understandably in America and have ridiculous postage costs to Australia. I hope the polar works out. It might be the next one I get.

Any cheap backup batteries yet ?

Any cheap backup batteries yet ? Ideally with wall charger.

I think the only one available right now is the stock Samsung batteries. You might be able to find a 50% off coupon. It comes with a battery charger. However I would wait for a company like Anker to release 3rd party backup batteries because I've found 3rd party batteries to have longer battery life than the stock batteries.

There is nothing. It's funny cause I had the G3 before this and there were a few preorders on Amazon already. I would think there would be more for the Note 4. What sucks is, Samsung had the spare battery with a charger for $20 but it sold out real quick. Who know's when that will come back in stock. I put my email down to know when they come back in stock, but I have done that before and never heard anything.

I can't post links yet because I'm a new user, but go to ebay and search for note 4 batteries. There is one from China that has a picture of three batteries and a charger.
I've used these batteries for my Note II and Note 3. They work great for about 9 months to a year. They still hold a charge after that time, but not as well as the stock battery. The stock battery will eventually crap out too; all batteries do. It's a great deal at $20 for three batteries and a charger. I also prefer to use this charger instead of the one that comes with the phone because it charges more slowly and will give you more charge cycles on your batteries. I would also disable fast charging unless you're desperate for juice because you will get fewer charge cycles out of your batteries before they start to suck.

Exactly this!
Batteries are not something people should cheap out on, for the sake of only £10 or so! Nearly all the cases posted around the internet of people's phones going up in smoke are due to cheap, third party batteries and/or chargers. Then there's the issue that most cheap third-party replacement batteries will have far less than the advertised capacity.
They're just a risk that is not worth it.

I can't post links yet because I'm a new user, but go to ebay and search for note 4 batteries. There is one from China that has a picture of three batteries and a charger.
I've used these batteries for my Note II and Note 3. They work great for about 9 months to a year. They still hold a charge after that time, but not as well as the stock battery. The stock battery will eventually crap out too; all batteries do. It's a great deal at $20 for three batteries and a charger. I also prefer to use this charger instead of the one that comes with the phone because it charges more slowly and will give you more charge cycles on your batteries. I would also disable fast charging unless you're desperate for juice because you will get fewer charge cycles out of your batteries before they start to suck.

Did you bought those from China? How is it? Anyone knows?

I love the made in China batteries.
I understand the concerns with using a cheap battery, but I've used the ones on ebay for years now without any problems or harm to my devices. The savings are not a mere 10 quid. You get three batteries for half the price of one. The made in China batteries definitely don't last as long as the stock battery, but I've never seen one blow up and I'm not afraid or concerned about it ruining my phone.
There is one legitimate drawback compared to the stock battery though. The NFC chip is embedded in the battery on the note 4 so if you use NFC a lot then clearly you should stick with a stock battery.
I hardly ever use NFC so I'll still use the made in China battery from ebay.

I agree 100% with you. I am not worried about the battery blowing up. Its rare. And for my S3 and Epic prior to that they served their purpose. Backup for when you run out of power.
However, based on other thread if I can buy Samsung's for 50% off battery and charger ($20-$25) I would do it, just OOS.

Yeah, personally I have bought those cheap Chinese batteries off of Ebay, and I don't think they are worth it. I'm not worried about them ruining my phone, that is very unlikely. They just don't last long enough. I'm waiting for a reputable company to come out with a set with a charger. Like Anker. That usually runs about $30 bucks with 2 batteries and a charger compared to what $80 for the Samsung one. Even if they are .01% more likely to ruin my phone, that doesn't warrant spending an extra $50 like some people would lead you to believe.

Anker are very good, and not cheap as OP was talking about. I would use Anker but not a cheap option.

But Anker hasn't been to quick to get batteries out. I would suggest buying the Caseology batteries when they become available on Amazon. They always put up a preorder with a really good price but a ship date that is a month away. I always resist ordering it hoping that something will come sooner but they are usually the first and by the time they ship they are more expensive. And they get pretty good reviews.

FWIW, when I went to charge the batteries for our trade in phones, both stock batteries couldn't hold a charge at all.. BUT the cheap extended batteries I'd purchased from china had no issues at all.
(As a matter of fact, one of the stock batteries had developed that battery bulge we've heard about, and I couldn't even put the back on the phone with it in!)

They're currently out of stock, and on backorder.

They get em in fast. Check 2x daily.

Odds are we'll see quick chargers paired with 2 batteries on ebay soon for $12 shipped or so, similar to other phone battery options.
Since that's less than 50% the cost of the Sammy's I'll just wait for a week or two for them.

there are several on eBay just be careful as some are just 3000 MAH and some are 5400 MAH so just choose wisely if you decided to buy from eBay but most offer 2/3 batteries for 15$ or so

can you post which coupon code you used? because the ones i'm finding aren't valid even on the other current in stock accessories.

Keep an eye on this thread for coupon codes.
