Has anyone ever tried Mugen Battery on our Vibrants?

Has anyone ever tried Mugen extended 1600mAh battery on our phones? I'm thinking of getting on and I want to know if its worth it.

Why get a 1600mah when theres a 1650mah by T-Mobile?
Sent from my SGH-T959 using XDA App

Because no one can find the friggin 1650s. Even the post dedicated to them doesn't have more than a dead ebay link for them.
Sent from my rough sketch of a Vibrant on a brick.

why get the 1650 when u can get 2800 on amaZON for under 20.00 us?

Well anything higher than 1600mah will cause the phone to get really fat.
I posted link above.

fat battery
I got one of those fat batteries from amazon and it doesn't seem to last that much longer than a standard battery. It also makes the phone look pregnant.

I am using a 3.7VDC 3500mAh Li-ion Battery for my vibrant and it lasts me for 2 days and a half without charge, Of course the battery is a little bulkier then the normal 1500mAh, & it comes with a back Case, its worth the cost and its for only $16 Bucks on ebay. Its worth the money Sweet

I got mine yesterday, but did yours feel like it didn't work at first? Cause I feel like it doesn't work, but I heard its gonna work after a week.

Well actually the battery was working fine when I received it. What you want to do is once you have the battey, deplete it till it fully drains out of power. Then recharge it with the charger they supplied you, don't charge it throu the phone. Once you see its fully charged. Chharge it for at least 1 hour more and u will get the full capacity of the battery. If your vibrant has a good kernel u will be set for 2 days straight. Hope that helps. Am using overstocked kernel

Oh okay, but the one I got only came with a battery and the back case for it, I don't know what you mean by "...charger they supplied you." Do you mean the Vibrant charger?

...he said dont charge it through the phone, which is the only way you can use the vibrant charger so that rules that one out, so by process of elimination and a lil bit of thinking the only option left is his came with a charger for the battery, probably a small dock type deal.
Just gotta think a little not too much to ask

i apologize for the late reply, I should of been more specific with the charger i was talking about. It is a USB/AC Wall charger for the Samsung Galaxy S i9000, Sprint Epic 4G, AT&T Captivate i897,T-Mobile Vibrant T959. You can view it on ebay, Amazon etc.

Anyone have tried these out? Seems like a good deal for a 2300 mah. Compared to ecell for example.

Yes i have 1. Pretty good. Lives a little longer than the 1800mah

Will these batteries work with the regular battery cover of the Atrix 4G or does it require a new cover like the mugen ones. If it needs a new cover thumbs down! If not I might buy 1
Let me know !
Also do you have any issues with the 2300mah battery's stats not reading correctly....I read that 2000mah is the maximum in which the phones hardware can read. If your 2300mah is reading correctly that's interesting.

I used these - very bad.
My atrix was not able to get actual charge state. Could see 100% and then suddenly fall to 0% and phone switches off. Or can see 5% for hours after full night charge.
Bad stuff

What's up everybody, I just ordered these & hoping they'll do the job. I've ordered from them twice before (nexus one, evo 3d), the batteries in the past have held up pretty good but I don't think these have nfc :/ I ended up ordering these cuz' the qcell nfc enabled ones were sold out/unavailable so I didn't wanna' wait, plus I haven't seen a review on these yet so I said eh, I'll try em' out. If you guys are interested in purchasing some for yourselves I've included the link below, the only thing is that you have to pay using google checkout :/

I always use the supplied wall charger that comes with these so Idk, lots of the extended battery reviews on here are the same voltage & they seem to be doing pretty good.

It's not the charger which matters but the phone itself which charges the battery, it's aiming for 4.3V as that's what it thinks it should have as the stock battery is designed for that. Although I haven't heard a single case of these 4.2V batteries having problems with being charged with 4.3V, that last part can be changed in the kernel and the charger chip driver. I'm getting some knock-off cheap battery myself so I'll see how it goes. This particular one seems quite steep in price @ $30, with proven ones like the PolarCell 2400mAh going out for half the cost.

you won't see the affect right away from overcharging. I use to play with a lot of batteries from RC, overcharging something we use to do get slight edge and boost at start. but it does have long term damage to batteries, specially lithium based. some cheaper batteries even catch fire.

Alright guys, got the batteries in the mail today, charging one & will report back later

Li-ion batteries have an overcharge protection circuit built into the battery pack itself and should prevent this from happening. If everything is working as intended, it should be impossible for the phone to overcharge a battery. That's not to say the protection circuit couldn't fail itself.
And I too played with RC batteries and you really can't compare those batteries with these. Different types of battery with different methods of charging.

It just keeps getting better & better

Any updates regarding your experience with these batteries? I used to own this brand for my HTC Sensation and was very pleased with it. Almost had about 400+ recharge cycles before the battery started to wear out. Looking forward on your feedback!

T989 Slim extended battery?

I'm at work and I got a customer that just asked me about extended batteries. I told her they're usually fat batteries that come with special battery doors.. but usually at least give 25-50% more battery life. Then she asked if there were any slim extended batteries. I didn't know how to answer her and all my gsearches came up with 3000MaH plus big boys. All I found was he Mugen Power 2000MaH slim battery. You guys know of any other options out there?

I am currently using an Anker battery that I bought off Amazon. It has slightly extended battery life at 2200 mAh. It is the same size as the OEM battery so no custom back case or chunkyness sticking out the back. Anker sells the single batteries or they sell a double pack with an external battery charger on Amazon, quite useful. I believe their products are on sale right now.

The Samsung galaxy nexus 2150 mAh battery fits in the s2 without any problems. Slight bulge on the battery cover though.

Anker 2200 mAh works perfect for me. I've been using 2 I ordered from Amazon for about 4 months. I get about 10 hours heavy usage time. I get well over a day on when I take it easy. Juice defender is an excellent addition to any cell as well. I would advise you to be careful when taking the battery out of the charger so you don't break the plastic that separates the cells. It can cause problems charging through the cell phone. Either way it's a great buy and I highly recommend.

Anyone know how reliable some of these aftermarket batteries are? I've been reading that some don't have NFC support and overcharge protection. Both huge no-nos in my book. Especially the latter.

You can charge them either way. Personally I use the external and the phone. I was just saying be a bit careful when you take your battery off the external charger. I have one battery that I can only charge through the external since I broke the small plastic separator... not a big deal though. It still works properly.

No NFC support in most (if not all) aftermarket batteries

Yes, most aftermarket batteries (like the one WangLung linked to), if not all, don't have NFC support as the chip is located in the battery. The same goes for the ATT i777, but not the international i9100.
You can tell on many of these by the 4 contacts- one is for the NFC. This is why a i9100 battery (with only 3 contact heads) will work with a i777 phone (that has 4 contact prongs) - the connector for the NFC would just be touching plastic.
Don't know about the overcharging protection though.

I have the Anker 2200 MAh slim extended battery in my phone and it works great! I usually get an extra hour of on-screen time than I would with the stock battery.

Anker battery is awesome
I purchased an Anker 2200 mAh slim batter 2 weeks ago, and I have been nothing but impressed! This battery rocks, I get 2 full days with average/light use (phone calls, 3 hours screen time).
Well worth the investment for 2 battery's + charger for around $25!

The one for $20 includes two batteries and a charger, while the $12 one only a single battery. For what you get with the $20 one, it never hurts to have more than one battery, especially if you're away from the charger for a whole day and you're using your phone often.
I do not own the Anker extended battery myself, as I am doing fine with the stock battery and I like having NFC ready if needed. But it does seem like a great battery, especially for the price.

Looking for S4 Mini third party extended batteries.

Hi
I would be very interested to know of any third-party extended batteries for the S4 mini and people's experiences of the same. I am looking to upgrade from my S2, but am waiting until there are bigger batteries available for the S4 Mini. As yet I have not seen any such batteries on ebay or the web in general.
Regards
Midgeslayer

Have a look at this. I'm sure you'll find what you need: http://www.batteryupgrade.gr/shopBrowser.php?shopGroupId=16167761#/shopGroupId/19772600

Looks like the first replacement batteries are showing up for our S4 mini. 2500mAh does not sound bad.
But does anybody know how the battery is important for NFC to work properly? There must be a reason for Samsung to write "Near Field Communication" on the original battery.
Edit:
Hm, seems like the antenna for NFC is located inside the battery. So no NFC with 3rd party replacements that do not integrate an NFC antenna.

Yes indeed. The battery holds the antenna for the NFC.

Well, there are 3rd party batts with NFC for S4 mini. I've never tested such equipment though and don't know if the NFC works at all.

In my experience, third batteries are false advertising.
I will get back with a site that measures all batteries how mah they claim and how mah they really offer.

I don't really think that you will get anything from this battery... Looking at it logically - how a battery with the same dimensions as orignal 1900mAh one can have 900mAh more? If it was possible then I thing that Samsung would do it in first place.
Just look at Galaxy S III, Samsung made a bigger battery, but it's bigger in dimensions also.

I agree, chances it it won't make any difference but for the lousy €5 I might as well try....

Depends on the quality of build... You probably heard of those cheap chinese wall chargers for iPhone, one of them even killed a person!
I other cases there is no risk, it would be just a battery with a bigger capacity.

I hadn't used it very intensively. Just browsing, email, facebook and such. Just after I posted though percentage dropped to 34 within an hour. Also experienced a lot of lags and freezes yesterday. Not sure whether its the battery but that's the only thing I changed. I'm back to the OEM battery now to see if the lags are gone now. Usually I end up with 20 to 25% after a full days normal use, which isn't that bad so if the new battery doesn't turn out to be a success, no harm done really.
