Well for the first, people get extra batteries so that when the first one dies(OEM Samsung battery that came with the phone) they can just pop in the new one by anker etc. And keep on chugging without charging. Hope that helps. Also, after so many charges the OEM battery loses some of its MaH amps so people will purchase a cheaper(anker tends to be about 10-20 bucks less) to replace it. Price is always a deciding factor to most consumers, especially phone owners.

I get extras because I hate charging my phone. When one dies I pop in a fresh one and go. I am getting two ankers Monday so ill have three batteries.

From Note 2 experience, Anker OEM replacement battery performed and lasted longer than Samsung battery. Period! Plus, as some others pointed out, you can use external charger to juice it up, and just swap batteries on the go.
For external battery banks, Anker is also the way to go. Go to my Review Link in the signature where I have reviewed and posted detailed write up for close to a dozen of power banks. 6000 mAh is a thing from the past. Right now new power banks have 10,000 to 15,000 mAh of capacity in the same footprint as old one. Plus keep in mind, the actual capacity of external charger will be 30% due to usb port conversion (going from internal cell of power bank 3.8V to 5V usb port, and back to 3.8V on your phone through usb port - close to 30% loss due to efficiency).

Yes that 6000 mah power bank will give you only 1 full charge, and the charging speed is equivalent to USB. If you are doing NAV or some other heavy power draw, the external battery may not keep up.
And if I have to carry a spare, the internal battery is smaller and I know exactly what I am going to get in terms of performance

im finding that the anker 2600 batteries i bought are better than my two samsung batteries. i have two samsung batteries because 1 came with my phone and 1 came with the brand new insurance replacement after i smashed that phone. pretty happy with anker. no need to add bulk to the phone with an extended. just keep a spare battery when needed. i have 1 in my camera bag, 1 in my backpack i take to work, and 1 i can slide into my wallet if it's just me and the phone.

I bought Anker 2600 dual battery and external charger pack. Love it. Been using it and swapping batteries out every morning instead of being tied to a charger. Good for trips where I make heavy use of Cell phone to watch videos and such.
Had one issue. the internal connector that the pins that connect to the battery kinda broke on mine. The piece the pins are attached to fell inside the charger case. No problem though just opened it up and hot glued it back in place. All that keeps it there from the factory is glue and mine just came undone. Happened while traveling with charger in a bag with a battery in it, possible something pushed it hard.

Good to know that 2600 anker is better than actual battery... I was planning to get the 3k zero lemon but every one suggests is not doing much difference

[Review] Zerolemon 3000 MaH Batteries & World's Fastest Wall Charger!

I have been using Zerolemon's 3000 mah batteries for more than a month and they are great! They last longer that your stock 2600 mah battery, well constructed, and are reliable. The other bonus is that they fit in your Galaxy S4 with your regular back cover! With 2x 3000 mah batteries you also get "the world's fastest wall charger for the Galaxy S4" from what they say, but that is wrong. The wall charger takes 11 hours to just charge one 3000 mah battery.
Conclusion: The 3000 mah batteries are excellent, but the wall charger will take quite some time to charge the batteries.
What's Included:
2x 3000 mah Zerolemon batteries
1x Wall charger (Works on both my Galaxy S4 and Galaxy S3 battery)
Best Price: http://amzn.to/14EocGI
Enjoy my video review :good::

After reading their description:
Wall charger is .6 amp stock is 2 amp. So it will definitely be slower to charge.
No nfc.
What is it, 3000mAh or 200mAh more than stock? They need to do their math. It's one or the other.
I'd like to see a side by side comparison by the numbers, I have been burned by aftermarket batteries before. May consider it but the fact there is no nfc may be a deal breaker.

Where is the comparision between stock samsung 2600 and the zero lemon 3000 as far as how long it lasts???
Thanks

Honestly, this is more of an overview than a review. I'd expect some actual statistics in the video such as overall battery time with stock vs zerolemon batteries (maybe running constant video or something), but all you say is whether or not it's a good battery. Sorry to be so negative, but this is really lacking actual "review" content.

I also purchased these batteries. NFC not being included didnt matter to me whatsoever. Anywho I would say im a heavy user: twitter, facebook, youtube, fun run etc.. and i easily get 16 hours out of one charge. Make sure you do the cycle for these batteries when you get them. The best cycle i had with the 3000 mah was 1 day and 8 hrs i believe.

Here is my proof since I foresee someone asking.

I bought these, good batteries, wasnt expecting alot longer battery life just wanted some extra batteries, if you are a power user dont expect to see a whole lot longer battery life. But they do give a little extra run.
As far as the actual company goes, Yes mine are genuine batteries, they should really make it so the instructions on the batteries them selves match the instructions that are on the card. Dont know if anyone else saw that.
Example, Batteries say charge for 8 hours prior to use. Card says 12. Card says kill to 1% before charging, the batteries dont.
Also the wallcharger....definitely isnt the worlds fastest. I can actually charge my phone while playing on it continuously while charging and it charges faster then the wall charger.
But hey, 2 extra quality batteries for 20 bucks. Still worth the 20

I see all these people bought these 3000mah battery packages...
Where are the side by side comparisons to a stock samsung 2600mah battery???
thats what I want to see...
Is it worth the 20 bucks? or just keep the phone plugged into your computer or car?

I bought the two 3000mAh batteries + wall charger as well. I have to say i'm disappointed with the charging speed of the wall charger. It kind of breaks the deal for me. I wanted the spare batteries with an external charger that would allow me to keep the batteries charged without having them on my phone itself. I guess i'm going to send my feedback to ZeroLemon, and see what they will do about it.
The batteries are good compared to the original Samsung 2600mAh one. Right off the bat when i used the ZeroLemon battery, with the same phone settings (brightness, mobile networks, etc), i could notice the battery draining a little slower.
I've read many online reviews on these 3000mAh batteries, and they were right about the battery being a bit bigger than the stock battery, although i couldn't really notice the size difference when i compared them side by side. The back cover will shut properly after some pressing on the sides. Nothing to be concerned about.
All in all, i love the batteries a lot, but it's just too bad the wall charger is practically useless as i'm going to be using the Samsung charger which is way faster.

I have bought 9300mAh battery from Zerolemon for my Samsung Galaxy Note II. I think this battery is so awesome, It is longest than any brand in this class. $44 is worth getting this battery. Highly recommended.

Thats sick! my stock battery lasts about 9 hours (i use it quite a bit)
Definately going to have to purchase one of these

I just ordered one from amazon for like 8 bucks! I hope it improves the already stellar battery life I get running CM 11 4.4.2

Can anyone comment on this battery?

I live in India and I am getting a better deal on this one.

Just got the Zerolemon 3000 mah batteries and wall charger off of Amazon. They are great. I also have a Hyperion 7500mah extended battery. I can get 2.5 days easily or of the extended battery, but due daily use i wanted something closer to stick size. The ZL 3000 batteries are perfect. I get about 5 hours more out of the Zerolemon over stock. 15 hours vs 21 hours. Enough juice you get me though the day. Will save the Hyperion for times when I may tether or be away from a charger for long periods of time.
Really good deal for $20!!

So i got a single zero lemon 3000 mAh battery coming in the mail. I have the samsung OEM battery charger when i bought and extra battery. My question is it safe to use the samsung battery charger since I wont have the zero lemon one that is provided in the link above? Thanks in advance.

Does anyone know where to get one of these batteries in the UK?

Same question here!

Portable chargers, external battery cases, extended batteries etc etc

Hi all, so I've got an S4 and the battery just doesn't do it for me as I'm quite a power user. So I've been looking into various methods of keeping my phone's battery topped up, especially on the go, I've had a look at portable chargers, external battery cases (as I had one on my S3 and it worked great, for about a week and then gave up) and extended batteries.
Now what I'm looking for is ideally something that isn't too bulky, has decent quality and provides a good solid charge to my phone. I also have a bunch of other phones that I want to keep charged, so an external battery case or extended batteries are looking a little weak here as a portable charger would do the trick for all of them, but then again they often seem to be quite bulky.
So my question to you is what would you advice? Ideally I'd like a solution that fits in the pocket and still keeps my phone topped, what would you recommend and have you bought something to satisfy this need yourself? I'm not really looking into extended batteries that add a whole lot of bulk, I'm hearing good things about Anker batteries and these 3,000mAh Zerolemon standard size batteries, but there seem to be so many variations of portable chargers I'm not quite sure what to do. Any help would be greatly appreciated!

I have the Zerolemon battery, it works well, but really, I couldn't tell much of a difference in battery life, and keep in mind, NFC is not included if you go with the Zerolemon.
Go to amazon and do a search for "android portable battery charger" there are a lot of options from small lipstick sized charges to big bulky ones, read the reviews and pick one that works best for you. Personally I am usually close to a charger so I have not found the need to get one yet, but I can see how it would be necessary for those that are frequently away from a wall outlet or car for extended periods. I might pick one up before my camping/float trip coming up this summer. If I did, it would probably be this one. http://www.amazon.com/KMAX-806-Flas...8-5&keywords=android+portable+battery+charger

I have an old external charger that came with a 3 panel solar folder. I used it a few times when camping and I could charge it all day and then use it to charge the phone twice. That was with an older 1900mah batter in the phone

Just a quick update, I eventually decided to settle with this EasyAcc iChoc 5,000mAh portable charger. I've had it for a few days now and it works fantastic, the build quality feels nice in the hand and the dimensions are the same as my S4 (and just as slim mind) it comes with two outputs, a 1A and a 2.1A one (using your own microUSB cable) and the 1A output has a built in microUSB cable. Very pleased with the purchase, it was around £17 on Amazon Prime:
http://www.amazon.co.uk/EasyAcc®-iC...&qid=1397737540&sr=8-1&keywords=ichoc+easyacc
Bear in mind I don't think the actual capacity is anywhere near 5,000 mAh however.

Charges S4 about 1.3 times.... So it's about a 3000mAh

Are you referring to the EasyAcc portable battery that I posted?

While I think you have made your choice .... I have used the callpod dou charger.... I had 10 of them until I started giving them away cause they were of no use with the phone I had before I got my S4. I have (5) Isound 16,000's 16,000 mah. That will keep my S4 or my wife's Iphone 5 up for about a day of intermittent use.... she can kill one in about 8hrs if she is on her phone and charging her Ipad at the same time. I also have (3) of the power bank 33,000s . 33,000 mah. I am not sure that I have ever killed this battery with my S4 alone. My wife can kill it with her iphone in 2-3 evenings of fairly constant use.... talking on the phone and playing games and I think charging both her iphone and ipad... (flipping back and forth between the 2. This battery will also charge most laptops. Her Macbook will get one full charge out of it.... if the computer is not on. With the computer on it last about 30-40 mins. My Htc Flyer has been on a 33,000 all week with off and on use and is still half full. Finally , I have a hyperjuice 150wh and a 222wh. The wife has been charging her iphone on the 150 and her ipad on the 222 all week and they are still around half full.

I finally got myself the Anker 5200 mAh battery. Does anyone know an app that shows the correct battery capacity? I got the sneaking suspicion that it isn't detected properly...

QuickCharge 2.0 External Batteries?

Can't seem to find any that have the higher voltage for QC 2.0 to charge a Note 4, anyone else have any better luck?

It's a bit new to see that in battery packs and multi port chargers.

yeah, that's a little pricey for what it is...

If I get a little more disposable cash, I'd consider putting a minimum quantity order in and sell a few to those on here at cost plus shipping. It's worthwhile to resell if you can beat other sellers to the punch and make a penny. Once these become commodity and the prices drop, it's not worth it unless you're a big time seller. The profit per piece usually cuts it close for the time you invest fulfilling orders and dealing with problem ones. I got hosed on Note 2 cases a couple years ago where the cases were crap. One drop and the Note would pop out. Couldn't get the seller to take them back, and I didn't feel comfortable selling them knowing I'd get complaints (if it happened to me on multiple occasions.) Still have them. Might just unload them cheap when I get around to it.
With the QC options out there, I wouldn't buy a battery or charger that didn't have one QC port on it at this point. Funny, all the people wanting their wireless charging. I'll take QC any day.

Going back to the cheaper option approach - you can get the Anker charger plus two extra batteries for $25.00 and this Anker 10,000mAh external battery for $23.00:
http://www.amazon.com/Compact-10000mAh-Portable-External-Technology/dp/B009USAJCC/ref=sr_1_4?s=wireless&ie=UTF8&qid=1422131778&sr=1-4&keywords=anker+power+bank
Swap out batteries and use the external battery pack plus the charger to charger the spares. Charging won't be as fast as Quick Charge but hey, it's on the spares. For $48.00 you have a whole heck of a lot of spare juice available. And there are higher capacity but pricier external batteries available.

I have the OEM charger and spare battery. I keep it in the center console charged. If I need to I swap and let the dead one charge. If I have a heavy day and can't charge I grab the charged spare. I use a pack to charge other things when needed and once in a while the phone. So if I were to replace it, it would be with one with a QC option. Not everyone is buying a battery pack specifically for the phone, but if your going to buy one, why not have the QC option? It's also less time you're tethered to a charger when needed.

Which Powerbank for Note 4

Hi guys
I wanted to ask which powerbank capacity do you recommend for the note 4 for at least one full charge ? I bought one from deboch 6000mha but I will send it back because its too big.

I've just ordered an Anker Astro 5200mAh:
https://www.anker.com/products/A1211012
https://www.youtube.com/watch?v=frhehPIqFKE
It seems that you actually get at most about 75% of the stated capacity from a powerbank (see this video: https://www.youtube.com/watch?v=zz4arPh-ch8). Even if you only get 66% of usable capacity from a 5200mAh Powerbank (as the video suggests), that should give approximately 3400mAh which is enough to charge a Note 4 from 0% to 100% (battery capacity of a Note 4 is 3220mAh).
The Astro 5200 is very pocketable at 5 x 3.4 x 1.7 inches, comes with a net travel pouch, and a USB cable, but I bought one of these tiny USB cables to use with it: http://www.ebay.co.uk/itm/131876034528

You need a powerbank that holds a larger charge than the battery of your device in order for it to get a complete charge. I'd suggest getting a power bank with at least 3500mAH capacity.

Much more pocketable and guaranteed one full charge is a spare battery! Only downsides are you can't be a good Samaritan and share and you can't use it on your next gadget

Yea, I have a spare battery too, and an external charger - I like to keep my options open, but it can be a bit of a nuisance removing my UAG case so sometimes a charger is handier.

RAVPower's 20100mah has been great for me, and includes Qualcomm Quick Charge and USB Type C support: https://www.amazon.com/Qualcomm-Cer...qid=1471276085&sr=8-2&keywords=ravpower+20000

xiaomi 20.000 mAh will be the best : )
http://xiaomi-mi.com/powerbanks/xiaomi-mi-power-bank-20000mah-white/

OP is looking for something SMALLER than a 6000mah Deboch, so suggestions for units over that size won't do. I've received my 5200mah Anker Astro E1 (mentioned above) and can confirm that it fully charges my Note 4 with a little to spare. It has a 2A output so charges quite quickly. Very pocketable and highly recommended, probably the best size/capacity ratio for carrying in your pocket:

Having used a few Anker, revspec and kasmish. I know i spelled most of those wrong. But they are all in the 10k mah range.
All of them will easily charge your battery 2-3 times. However some claim 2A but just isn't as fast. I much spend a little more money on a Quick charge 2.0 certified one. Quick charge 3.0 is out for a handful of new phones but the note 4 doesn't support it and most are lik the $50+ range.
Get a QC2.0 small 10k and your covered til the end of the phone life. They will run you $15-30. They are roughly double the size of your note 4 in thickness and thats it. If you can pocket your note 4, you can pocket the battery. But i normally pocket the battery pack and hold the phone. I keep it in the bag tho.
This to me is the best and future proof method. A spare battery is the fastest to go from 0-100 but w/o a spare battery charger, it could be annoying as well as it only works on the note4.

Hi guys
I wanted to ask which powerbank capacity do you recommend for the note 4 for at least one full charge ? I bought one from deboch 6000mha but I will send it back because its too big.

Xiaomi 20 000 mah. It has fast charge

If that's just for your phone, get a spare battery or two. Preferably with an external charger.
If you got your Note4 when it came out and use it regularly, your battery is probably significantly degraded by now or is starting to do so. So buy that new battery.
If you intend to do so, stay away from those cheap "Samsung" batteries on Amazon or eBay. These are all likely to be fakes or rejects. Either buy real (expensive) ones in retail packaging or reputable third party brands.

Anker powercore+ 10050 has qualcomm quick charge and is the perfect size. Amazon has it in a package with the anker wall charger that charges extremely fast. I now have Anker chargers for everything electronic in my life. Anker for life
