Mugen 1500mAH

I am thinkin of pulling the trigger on this
http://www.mugen-power-batteries.co...ery-for-for-htc-desire-hd-softbank-001ht.html

If you get it, let us know your results. Too bad it's backordered for a few weeks. Hopefully those positive reviews aren't fake. 1500 mAH might be impossible in such a thin battery but who knows.

Mugen batteries are known to under preform from their mAh claims. I would be wary a any battery that claims more power without needing a new battery door as the only way to substantially increase the mAh is to increase the size of the battery. There is also no stated dimensions on the page.
Until a company figures out that they can add to the length of the battery with a modified door we're not going to see numbers beyond 1300.
Edit: I think HTC may have something in the works. This is what I'd wait for. Sales of this phone are through the roof so it makes sense that they could do this and get a return on the investment.

Oh wow. This is awesome. I guess I'll sit tight to see what HTC has in the oven.

(Regarding a possible extended HTC battery) I'm more than pleased with my battery life, but this is awesome. I would definitely buy - right now I'm getting about 1.5 days out of my phone, if I could make it to two days and charge every other night/ insure a full day with HEAVY use I would be very verrrry happy.

How are you getting such life?

This is basically how I use my phone
-CM7
-Regular Use: Browsing internet is somewhat light, because I make good use out of the Pulse newsreader app. I'll check twitter/facebook a few times, make about an hour or so of phone calls per day, send about 15 texts, check xda a lot, and use audiogalaxy to stream my music library, and use runkeeper to track my runs when I'm running outside (when it is nice out) and I rarely run for less than an hour.
-2 Google Accounts, one of which is set to sync in the background (for gmail, calendar etc.)
-Auto Bright
-Wifi/GPS left on
-Social accounts syncing manually
I don't ALWAYS get 1.5 days. I get 1.5 days usually when my usage is somewhat light. I usually make the judgement call the night before if I need to charge or not. If I do charge after one day of pretty heavy use, the battery is almost always above 20% after a solid 24 hours.

Anyone else got HTC to tell this too?
It sounds like they just said that to get people off their back

Give them a call and see what they tell you.

Since no one posted I thought I'd give them a call and it turns out that churro7 might be right. I was told that HTC doesn't manufacture the batteries and was given a list of "Authorized" accessory stores online. She told me to check with them. So it sounds like the guy in the other thread was probably fed a line of ****.
The only thing HTC would make looks like it would be the new door. That's not to say they aren't contracting out the battery but I'd like to hear this from a credible source before I buy into it.
For the time being Sedio's 1300mAh looks like the only option.
Does anyone know of a battery that will fit but is longer? Obviously the contacts would have to line up right.
The dimensions are 52mm x 46mm x 5mm with the 46 being where we can go longer. The Thunderbolt's???
If I knew for sure one would fit I would order it along with getting HTC to send me a replacement battery door. Then I'd take the power tools to my original door to see if a little tweaking might make it work.

What about the mugen?

I would rather buy another stock one than buy a Mugen.
Look at the results of other Mugen batteries here.

You think this one is the same as the others?
sent from planet snarf

Unless they are better able to utilize the internal space of the housing there is no way to extend the mAh capacity without also increasing the size of the housing. It would take new technology.
I'm not here to tell you how to spend your money. If you want to take a chance then by all means get yourself one. Then report your findings good or bad. That way others can make a more educated decision.

Don't waste your money.
Just Google Mugen batteries. You'll see plenty of negative feedback regarding their batteries.

100% fake.
Sent by Skeletor from Castle of Greyskull using XDA Premium App

I've got one of these. However they are fake? The battery life from what I've seen is not too much more than the normal battery. I've got another which came with my dock and I don't see much difference between that which is 1600 and the "2400". Also I may not be the best person to comment on it as I change my rom so much I use a lot of power in different roms which use more or less power.

It's not fake!
I have this battery about a month now and it's really great ok it's not sooo big but it lasts at least 2 days of full use,so obviously it's not fake it's really great and i think it worth to spend 10 bucks for it...

Please guys, be realistic.
How the hell should some unknown manufacturer put 2450 mAh of power in the same technology (Li-Ion) in the same size and shape in a battery with the same safety standards?
Based on basic chemistry knowledge that is pure bull****.
Even Mugen had problems pressing 1500 mAh in the same size and I'm sure they had to make the walls a little thinner (what is pretty risky) for that amount of energy-rich mass.
That is absolutely impossible and it is naive to think it is real.
It may be a halfway good replacement for the stock battery but it does never reach 2450 mAh. Never.

All of you guys who think the battery life is longer than stock may think as a placebo effect. As Dr. Lele said it's impossible to pack so much in so little size as of today's technology.

lol, the only battery that has better performance than the OEM one, is Mugen's.
They managed to squeeze 1500mAh into the battery.
I am planning to commercialise a 3000mAh Gold (etc) battery on ebay, with secret Chinese circuitry, for just €6 (no, not really)

what i've learnt about replacement batteries -> if it looks too good to be true, it DEFINITELY isn't true.

Very true. I think a lot of it is the placebo effect... I tend to on a morning go and get that "2450mah" battery instead of the stock HTC ones. Most the time I cycle through the batteries but if I have to choose, I choose that just because it may get a little bit better battery life.... But I'm also worried it's cheaply made and might leak or something inside the phone..

It's hard to believe, that some unknown facturer could produce such a battery :l

not that bad...

I have tried it have it and not using it because is piece of crap. It was good on the beginning and than it stopped holding the charge... very short life time....crap

over 2000mAh for less than 10 bucks? suuuuure....
oh wait...it's got a gold label! must be legit!!
Ive got a 1900mAh battery which is a good chunk bigger than the stock 1230mAh battery from htc and i won't ever believe that someone can produce such a "golden" battery out of thin air....

Unfortunately these batteries are likely going to only have 2 of the 3:
1. Upgraded capacity
2. Safety
3. Longevity
The only other option is a 3.8v chemistry battery, which is being used by Motorola, but it will likely not be fully charged by the phone.
Anyway, the stock battery gives 4.55 Whrs, a 3.8v version would give 4.67 Whrs. Which is to say, you're basically getting nothing extra.

Meh no trust gold battery...

No, the answer is that it is physically impossible to produce such a battery. Please try again.

Standard fit / high capacity battery

Do any exist, which are safe and reliable?
On previous notes, I bought a slightly higher capacity Mugen but can't find any for the note 4 (in the UK).
My phone is now 9 to 10 months old and the battery is tiring (I think). Maybe a refresh is due. I can imagine the higher speed charging kills them off sooner too. ANOTHER good reason why the Note 5 should have a removable battery. A a built in battery will be performing under par in no time.

How much extra juice do you get from normal charging?

I hope you find what you're looking for... I am hooked on high capacity batts, and now even the little handed wife can handle a Hyperion 8000 batt with TPU case easily- they're not as brick-like as the zerolemon. Bought a new 8000 and a case for a total of 38 bucks with free shipping on amazon yesterday.
But everyone has their own way of wanting things- hope it works out. If it doesn't, though, I'll offer that it really doesn't take long to adapt to the Hyperion type with it's case. That same case works with the Anker 6400 too. Both have been great performers for me.

Thanks for your input. I'm more inclined towards the standard fit because of the accessories I already have: the car support, the cases, etc.. An oversize higher capacity battery would imply further investment in other stuff, while a standard fit would just (hopefully) improve a little on the OEM battery. If any of the batteries mentioned can fit the original samsung car windshield support I'd consider them a an option.

I just received this one today and so far it seems pretty good. Same size as OEM but it took noticeably longer to charge so the extra capacity seems legit. I had a Deep Stretch for my Sensation back in the day and it was great, so we'll see after a few days how this one performs in the ol' note 4.

I saw that battery, but passed it up due to the blurry photo (and the battery looks in the photos like it's a cheap battery with a sticker on it) and the generic reviews (as if the seller may have made a few of them). It just all looked like a cheap battery to me.
Let us know how it performs. Longer charging time may not indicate a bigger battery, especially if the battery really is a cheap Chinese battery or something.

OK so after a couple days with this battery I can say that it's good. The more I use it the better it seems to get too, on the first day it was roughly the same as my stock battery but today it's lasting a lot longer. I am getting a noticeable bump in overall life, ending my day with about 30% more juice left than I normally do.
Deep Stretch is legit, like I mentioned before I had one of their batteries a few years ago with my Sensation and it gave me noticeably more life as well. These aren't good if you're wanting a major increase in battery life, but they're great just to get your phone comfortably through a day of moderately heavy use without having to bulk it up.

This battery uses new technology? How could they made a same size but much higher capacity comparing to stock one? Could you post your onscreen time with this battery?

I am always skeptical about batteries that claim higher capacity while not being physically larger. Not saying these are bad but for I wouldn't buy it for the bigger number on the package. Personally, I tend to go with OEM batteries, bought with retail packaging from a reputable seller. Sure these are too expensive for what they are, but at least, I know what I am getting.
It is worth noting that li-ion/li-po batteries degrade slowly over time. So when you change your year-old battery for a new one, you are very likely to notice an improvement, even if you replaced it with the exact same model.

Best Extended Battery for Note 4? Hyperion, ZeroLemon or something else?

I've been looking around at the extended batteries for the Note 4. Which one do you consider the best?
Right now I'm leaning towards the Hyperion 8000 mah version.
The ZeroLemon does seem to have more capacity, but it does seem to have issues involving the battery reading because of the TriCell design? Can anyone confirm this?
I suppose then that would be combined with the ZeroLemon case. Unless a mod is possible?
By mod, this is what I mean:
http://forum.xda-developers.com/showthread.php?t=2530547
Anyone try something like this with a Note 4 Otterbox?

The reading issues are resolved with a custom kernel such as Emotion, which is patched to recognize the added capacity. I don't have the ZeroLemon or the Hyperion, but I do have this one and I quite like it. It is an off-brand, but I get exactly 3X my normal battery life with it, so it's legit and a good discount alternative to the ZL if you're trying to save a few bucks. I've tried to fit it into my otterbox but it's too bulky. Supposedly the official ZL cases will fit it though.

Zerolemon is pretty good. I don't really have any complains and I get anywhere between 10 to 19 hours of screen time on average with 12-15 being the average. The cover is very beefy and protective. The readings however can be inaccurate and when I sense this I just reboot the phone and it magically adds anywhere between 5-30%. There are some workarounds but they're a bit problematic. It's best to use a custom kernel that is especially tailored for zerolemon or extended batteries in general.
I switched to 5.1.1 on my 910C and flashed http://forum.xda-developers.com/note-4/development/n910c-kernel-5-1-1-stock-tw-permissive-t3206548/ by shreqg2 and it's working well as far as battery accuracy goes. The downside is that it doesn't have the 5.1.1 stock kernel cpu governors and overclocking the stock kernel provides (it can go up to 2100Mhz on BIG and 1900 and 200 Mhz on LITTLE as opposed to 1900Mhz BIG and 1500Mhz (or was it 1300?) on the 5.0.1 kernel. I guess it's not really a big deal since I've been stuck with the lesser frequencies since 4.4.4. Hopefully someone can write a proper kernel with the recently released kernel source code but I'm not sure. Really though, a lot of kernels have extended battery considerations and I'm just testing.
Edit: added screenshots with the new kernel. Rebooting gave me about 5%. It's working very well so far but this is the first discharge since I flashed it. Looks promising. It runs very cool too.

I'm going to be getting the SM-910W8 as I live in Canada (decided to go with it after the disappointment of the Note 5 and because apparently, according to the carrier phone salesman I spoke with, the Note 5 has been having reception issues and they aren't sure if it's hardware or software).
Not sure yet if I will go with an AOSP or TW based ROM though. It's a decision I have yet to make. But so long as the ZeroLemon has the full capacity it should be good. I am tempted though to go with the Hyperion as it does seem to be a single unicell and I have an offer for a cheap Otterbox Defender (which should keep it thin and protected).
Any kernel recommendations for extended batteries and performance in general?

Happy with Anker's 6440mah battery I recently bought, % indicator is accurate and doubles my usage time.
The back cover is slippery compared to the original.

Hi, i take here my "long" experience with extended batteries for different phones. I used Anker and Zerolemon brands.
Since I started to use my Note 4 (last February) Zerolemon's customer care replaced me the battery (10000mAH) because the phone turned off suddenly after only few days of Zerolemon battery use.
The new battery has lasted working fine for about six months but since one month I still have problems even if they are not frequently like first time (now i'm still using the battery..).
I have noticed that when you press at the top of screen the phone turns it off or restarts and I think that is an issue that concerns the contacts of battery to phone. I applied a bit of tape to keep the battery as good as pressed into the slot to avoid contacts issues.
(Probably the battery is too heavy to warrant a good fitting...and maybe the 6400 Anker could be the best solution..)
However I noticed that even when I can ensure that the battery is fine fitted the phone turns off or restarts anyway. In these cases I think that is an internal issue this time.
I don't know if these issues concern only first stock of Zerolemon's battery and now Zerolemon has fixed the issues.
In my experience I remember that I've never had these inconveniences in my S3 phone with Anker extended battery and in my S4 with Zerolemon battery.
I'll follow this thread because I'm searching a best extended battery for my phone...
P.s.: I use Zerolemon case with clip/ holder
Sent from Note 4 device - Rome - Italy

Ive had hyperion extended batteries, zero lemon batteries, and others and I have to say Anker makes one of the best batteries for phones, period. Hyperion has some stylish cases for their extended batteries which I love but their batteries aren't one piece and more like 3 pieces attacked and covered with a sticker. I never had any problems with it but its not as good of quality as a zerolemon or an anker battery would be.
Anker extended batteries have a plastic back that holds the battery and is a much more premium battery. Also their customer support is superb. My Anker 7500mah battery went out on my GS3 once and I sent them an email and boom they give me a new case and battery free of charge.
Zerolemon batteries are also known for their quality but they don't try to hide the fact that they make brick sized batteries and that's a downfall in my opinion because a phone with an extended battery still needs to be managable and fairly easy to hold but Zerolemon's 10,000mah BRICK may hold tons of juice but isn't practical. But they still make amazing batteries.

There was a battery thats someone posted that fits our existing case. I am unable to find the link. I think the battery was 5400mha. Anyone what the wed site?

Also has anybody notice that MYDE and Anker has very very similar description.

hey guys i have been using the zero lemon for some time now, i think its been a year now i believe. it started acting up on me after a year, it would reboot on its own, i know its the battery because i used the standard one and it works fine, (im on it now) so i was looking to see if there are any better batteries, i found one chinese base and said its 5600 mah so when i get it, i will update and let you guys know if its a good buy. they said its standard size and it uses a charge of 4.4 but we'll see. just felt like giving my two cents. how is that ebay battery going since you have been using it? whats the amount of time you are getting on it? my main thing is to have it not run out of battery for just ONE full day. I can care less for a battery that stands 3 days since I do go home and sleep sometime and I can charge it during that time.

It might not be the problem with the battery going bad — I had the same issues: constant reboots after a year usage…
However I noticed it would always reboot while handling the phone — I'd put it down on the table, throw it on the bed. Got me thinking it might be some looseness in the contact — the battery seems tightly stuck in — but anyway I tried and jammed a folded strip of paper in the bottom edge of the battery compartment, so that a piece is jammed under the ZeroLemon battery and a piece on its side.
Since then — zero reboots — the battery is rock solid — so I think after a while the battery gets microscopically loose — it being heavy and all — and that causes the reboots. My paper fix solved that and it's been perfect since!

What is your phone model number? can you tell us what is your screen on time (SOT) with this type of battery?

So-called 'slim' extended batteries make me suspicious.....

For years now manufacturers have thought we prefer having dead but omg so thin phones instead of ones that actually make it through the day. I've always bought phones that had removable batteries so that I could buy extended batteries and turn my phone into a brick that allows me to charge it at night and use at will during the day. Most of these are oversized and require a special back cover. However, I see a lot of 'slim' extended batteries that can fit into your current phone without a bigger back. They're plentiful, and they're cheap. So why don't manufacturers just include an extended battery that is the same volume but more capacity?
I suspect that perhaps they're less safe? I recently had an extended battery start bulging inside my phone and pushed the screen up a little. I wouldn't have noticed if the screen hadn't started coming up. Scared me a little, we've all seen the pics of phones that have exploded in people's pockets.
Does anyone know more about this than me?

I've never had an issue with the extra large extended batteries that require a special back. Those always give a huge boost to battery life.
