A quick overview for those who might be thinking about the OEM Samsung wireless charging replacement back cover for the Note 4. I also get into a bit of risk vs cost analysis towards the end.
I have compared both the Qi version and the Powermat version. This information applies to both. They are physically identical. The only difference is which charging standard they support.
Model EP-CN910IBU
Output 5.0v 800mA
S/N RCIFA
MSIP-REM-SEC-EP-EP-CN910IWK
Made in Vietnam
MSRP $39
Be aware these replacement covers add thickness to the handset.
Stock handset (non charging cover) plus glass screen protector: 0.360"
Handset plus EP-CN910IBU wireless charging cover plus glass screen protector, 0.425"
The charging cover adds a net thickness of 0.065." While this doesn't sound like much, it is enough to prevent most cases / enclosures from fitting over the charging cover.
These measurements are taken with a precision micrometer (certified to an accuracy of +/- 0.002")
As a common reference, an average US $0.25 quarter measures 0.065."
Imagine wedging a layer of quarters in between your phone and your case. Chances are it won't fit. Do you really want to use an $800 device with no case? The only case option would be a dimensionally forgiving non rigid rubber bumper.
When used with a Duracell powermat, the charging works as expected, albeit at the slow 800mA charging speed. The sensitivity of proper placement of the phone, centered on the powermat is still an issue. Even a small 0.25" movement out of center will stop charging.
Here are some simple calculations that allow us to directly compare *maximum* charging speeds using the basic electrical formula of Volts x Amps = Watts
Standard Wall charger 5V x 2A = 10W
Samsung adaptive fast charger 9V x 1.67A = 15.03W
Samsung wireless charging cover 5V x 0.8A = 4W
This comparison shows the wireless back covers charge at a rate of that is 60% slower than a standard wall charger and 74% slower than the adaptive fast charger that shipped with our Note 4 devices. In my opinion, this wireless setup is only practical for overnight use and possibly as a trickle charger in an office / desktop environment. It is not practical for use as a primary daytime charging system during frequent and heavy use of the handset.
The cover was $39, the powermat was $50 for a combined cost of $90. Car charging cradles are presumably another $50-$70. As a completely wireless charging solution, this costs about $200 and takes 3-4 times longer to charge.
I purchased this setup as a safeguard against damage to the usb port form a lifetime of plugging in charging cords. I have experienced usb port damage / degradation on previous devices.
Conclusion:
Consider that most of us carry an insurance policy through our provider for about $7 / month ($168 spread out over 2 years.) If you ever use the insurance due to damage, theft or loss, we pay a $200 deductible. Consider that most of us will upgrade to a newer handset within 2 years. This gives us a combined contractual insurance cost of roughly $370 across the 2 year lifespan of the device, and only if you end up replacing the device for *any* reason, not just usb port damage. Otherwise you pay only the ~$170 over 2 years.
The cost of "physical" insurance by way of wireless charging and a rubber bumper case is well over $200 all at the time of equipment purchase.
In my opinion, this high cost and slow speed of wireless charging is not sensible. I will be returning the equipment and returning to corded charging and my favorite case. I will keep the contractual insurance thought At&t. This risk vs cost analysis with corded charging is acceptable to me.
Thank you for your thorough review. I just purchased the official case yesterday from Samsung with a 50% discount coupon, after which, I started researching reviews and cases for it and found that many of the cases I was contemplating on purchasing were no longer fitting. I previously owned the Note 2 with a stick-on qi wireless coil and it worked great so I was leaning towards the same solution for the Note 4 but reading reviews about them seemed to point that the fact that it interferes with the NFC module. I use SoftCard (formerly ISIS) on a daily basis so this leads me to use the OEM back.

this is a silly "review" and an even sillier analysis.
It completely ignores the fact that all your data is on the device and if you ever have to replace it its a huge pain to back it up and restore it.
It also completely ignores how fragile the device is without a case on it.
It ignores the problem of fumbling around trying to find the correct way to insert the usb cable into the microusb slot (and if you insert the wrong way the tab can snap off) in the dark and trying to mount it on a car charger when you want to just get in the car and drive. it ignores the fact that wires running everywhere make a mess.
I have an iblason armorbox case and the samsung wireless back. Case fits perfectly, when i want to charge i just throw it on the charger. phone doesnt get below 90% throughout the day. I have an ebay 6000mah wireless charger in my bag, a wireless pad in my bedroom in a box and a wireless car charger. When i get home i literally throw the phone into the box and its charging instantly. i put the phone on my car cradle and it charges instantly. I put the phone with a rubberband in my bag attached to the wireless charger and it keeps charging while in my bag. no wires required. once a week i connect the usb cable from the 6000mah portable charger to a computer and leave it. overnight it gets topped up and ready to use for the next week. ive dropped the phone twice already (bumped it off a table and it fell from a placement on top of the car to concrete) with no issues. i dont have any silly insurance and the phone is zero hassle. i can use it in the rain, snow, dust, mud etc without worrying. the phone is always at 100% (never gets below 90%) and i dont need to worry about running out of battery.

Thank you for your opinion. I will keep mine.
I backup on a regular basis and restoring is easy.
I agree the device is fragile without a case.
I don't want the armorbox or otterbox or any other case that significantly increases the dimensions and bulk of the handset.
I don't charge in the car because I have short drive times.
I don't care for having to box or bag my phone throughout the day.
My job is not at a desk so I can't let the phone sit on a charging pad while at work.
I didn't want to spend hundreds of dollars on three or four wireless chargers to be distributed throughout my daily locations.
Wireless charging isn't mainstream enough yet to go completely wireless across all devices within reasonable costs. Other devices still require the cord mess. I am an "all in" or nothing sort of person.
The main reason for keeping the insurance is replacement in case of theft. Any new electronics are theft targets. I have had 2 phones stolen in the past. In one instance, I located the thief, removed a few teeth and repossessed my phone. The other went offline as soon as it was stolen and was untraceable. The insurance saved me from buying a new $600 handset out of cash.
Regardless of either of our subjective opinions, I mainly wrote the review to post the facts and figures of physical size and power output limitations. I will wait for resonant charging technology to be released and re-evaluate the cost benefit at that time. My analysis and opinions are there simply to get people to think about the pros and cons.
Wireless charging is way overrated imo. It charges much slower and you still need to have a cord for the charger itself (obviously). It literally takes almost the same amount of time to plug in the USB cord as it does to find the sweet spot of a wireless charger. At this point it's simply a novelty imo. Nothing more.
Each to their own. Any good 3 coil charge base has an enormous sweet spot, so hunting for position is not an issue at all.
If you get calls at night a lot (for work or other), the wireless charging is a god send. Trying to plug it in multiple times in the dark is ridiculous.
Now, when we have reversible connectors, my opinion might change.

I hear you man, I'm not saying it's totally worthless, but it's a very niche product imo. Like you have pointed out, it serves its purpose for some people. But I think for the average Joe, plugging in is just fine.
I do see where you are coming from however.
I have been reading about wireless charging for a couple years and never really pursued it on my Note 2 because I was with Verizon and they naturally removed it as they typically screw up phones somehow. I saw so many people that loved it and would go to great lengths to enable it. I decided after switching to T Mobile a couple weeks ago that I would give it a shot. I bought the OEM back and a cheap qi charger off of eBay and was disappointed with having to adjust my phone on the charger to hit the sweet spot. I decided to buy a Tylt charger and wow what a difference! I can literally place the phone on the charger in my case with no concern of finding a sweet spot because the whole charger is the sweet spot. It even works great through my wifes thick leather case. I love it and I find the rate of charge to be at least equal to a standard charger ( not fast charge) and that's great. I watched some netflix last night with my phone on the tylt (45 degrees)and it actually charged while streaming. I haven't personally plugged a phone in for more than 2 years since I just swap batteries out of my Samsung spare battery charger but now when I'm working or surfing at night my phone is always charging wirelessly and I never wake up with a phone that's less than 100%.
Even though it subjectively feels like wireless is as fast as a standard wall charger, it is not possible.
Manufacturers specification for wireless chargering is universally 800mA, or 0.8A.
Check my math in the first post. At 4W wireless chargers are less than half the speed of of a standard 10W wall charger.

"well over $200"? The qi charging back is $40. I got a 3 pack of Qi chargers for $60 (nokia, they come in a bunch of colors) so I could have one by my bed, desk at home, and desk at work. Numerous others are available for $10-$25 on ebay and other retailers. I'll happily pay $100 (qi back + 3 docks) or so to never touch the USB cable, fumble with a cable end in the dark, or try the cable backwards. When charging is easy you don't care about charging speed as much. 0.5 seconds to dock or undock (without even looking) will spoil you.
While I have multiple devices, I end up keeping my devices for 3-4 years with secondary uses. So even if I do get something new within 2 years I don't want the secondary device to die just becuase of a horribly designed charging cable that makes my first nokia dumb phone from the 90s look awesome. Imagine that after almost 20 years of USB might someday actually be reversible, maybe in 2015.
Never understood why the audio jack on today's phones is robust, easy to use, and impossible to get backwards. You could use it 10 times a day for a decade, yet most rarely use it. Nokia used to use a similar connector for charging, I could manage to plug it in with my eyes closed an one hand behind my back. To charge a phone daily you end up with a tiny fragile usb connectors that's easy to get backwards and difficult to get in correctly on the first try without careful examination. Already lost one phone to usb, I'm trying to avoid losing a second.
Both the microusb connector and expoxied in batteries reak of planned obsolence to me. Thankfully the note 4 can minimize both problems.
Oh, one last thing. The Qi Chargers do lose some efficiency. So if you get a charger that's USB powered you end up with a poor charging speeds. So I'd get one of the ones that come with their own wall wart. I use the nokia DT-900 (which comes with it's own wall wart) with my nexus 5 and it charges pretty quickly.

I purchased the Caseology Carbon Fiber case to see if I'd have any luck with the OEM charging back....and it worked! I posted pictures here: http://forum.xda-developers.com/showthread.php?p=57275699#post57275699

I have the wireless charging S view cover in combination with the S5 charging dock. I agree with what you are saying. The charging is really slow. Especially for such a high capacity battery used in the Note 4. I would not buy this setup again.
Does the qi back protect the camera?
Yes the qi back protects the camera lens in terms of keeping the lens from scratching on surfaces when you set the phone down. The added thickness casues the back cover to extend just past the lens.

Actually, Ive found that it does not extend past the camera lens, it makes the camera lens functionally flush with the back. Im a little disappointed in this and sort of wish it was "slightly" thicker. If it was, i think i would end up going caseless. I may end up doing what the OP described and going with the regular plugin. The batter last so long, i dont really plug it in except right before bed, and even then, i dont even need to charge it overnight anymore....
I'm coming from years of android phones and have always purchased wireless Qi adapters for them. After experimenting with several different brands of receivers over the years, I became a believer in the Nillkin brand. They cost a little bit more but they are way better built. I have always bought this receiver and have never had a single issue with mine or my wife's galaxy notes. I recently picked up a note 4 and after using it for a few days, I realized why I stay with the note brand. Absolutely amazing phone. Naturally I waited till Nillkin made an adapter for my phone and picked one up.
I placed it on charge the first night and when I picked it up in the morning, I nearly dropped it due it being so hot to the touch. That has never happened in any of my phones. Obviously something is not right with this thing.
Here's the weird thing....
I'm running "SmoothKat" rom but have a stock rooted back up. Oddly enough, when I restored to stock rooted and placed it on charge, It would still get quite warm but nothing like it was on the custom rom. I also tried turning off Fast charge option but no dice. Anyone have any advice? Is anyone else having an issue with the wireless charging making the phone hot?
BTW I'm using the TYLT Vu charger.
Thanks in advance...
Same charger here, using the OEM charging back. No heat issue.

Weird... It has to be this Nillkin receiver. I just searched around and noticed the Nillkin receiver has a significantly larger output of 850Ma. Most other receivers are 600-750 max. Could that be the issue?
I have a couple of receiver cards too, no heat issue with them but could not get tap to pay to work.
Hmmm that's never happened to me, and I have the same Nilkin charger. Maybe something with your phone?
Was the charger equally as hot?
Very strange. It seems the issue has worked itself out. I woke up yesterday and the note was slightly warm to the touch. This morning, completely normal temperature.... Weirdest thing... its like it learned what was going on in the past few days and fixed itself.... Mind blown.
Thanks for the help!
I had the same thing happen. I was using the OEM back with my TYLT, Airdock and Qi infinity chargers and it was running cool. The phone was too thick for my case so I switched to a Enpower transmitter with the original back. It was much slimmer but got WAY too hot. (I only tried it on my TYLT and decided not to F with it anymore.)

That's really weird. It may be something with our phones? I don't like the bulkiness of the oem cover so I was determined to figure out what the heck was going on. Shame I wasn't able to get to the bottom of this. Ill keep this thread updated as the days go by. I'm sure we aren't the only ones that had this issue.
Maybe they use the extra thicknesses for heat dissemination. It has a metal plate near the bottom on the inside, maybe that acts like a heat sink. I am sure their engineers did not take the decision to increase the thickness lightly, there must be a good reason...
And yes they should have baked it in by default. A flagship phone needs this built in, they were just greedy for accessory sales I guess.
Well, I'm glad the problem solved itself for you, OP. I don't know why that would have ever been an issue, but hey, if it ain't broke, don't fix it.
Same problem here with *Nillkin receiver, my note4 get really hot on charge.
My nexus 7 gets hot when charged using Nokia wireless charger. It stays hot even after charging is done. As if it won't stop charging so the energy needs to be dissipated somehow how so lt just generates heat.
I would NEVER use wireless charger on my note 4 because heat kills battery life.
I use a cheap ebay charger and wireless receiver that fits into the normal backcover...
It warms up while charging but nothing too hot. Just like charging normally by cable... Ofcourse, the cheap wireless receiver only gets 600ma max from the wireless charger.

Then the fault is with the Nexus 7 ? Sometimes i pick it up from the Nokia charger hours after it is done charging at it is still very warm, even almost hot.
Tbh I wouldn't be surprised. The nexus 7 I have has lots of issues like random reboots, touch screen issues. Many people have these problems. ASUS really screwed up the 2013 nexus 7.
Or do we have to buy one separately?

In the Netherlands there is a pre-registration offer which gives the pad for free. Otherwise you have to buy it. The retail price in the Netherlands for that charging pad is €24.99 so that would probably be $24.99.
Wireless charging pad included in preorders via Canadian carriers.
I'm guessing BestBuy, etc. in Canada, US and elsewhere will be offering the same.
Only late buyers will have to buy it separately. I think I saw $25 which isn't bad.
I'm here in the US, so all that doesn't apply to me.... but HOPEFULLY the US carriers will do the same! If not $25 isn't bad at all!
On a side note... Is there "faster" wireless chargers, or do all wireless chargers charge at the same rate?
I think most of the US carriers as well as US BestBuy and other retailers will be offering the wireless pad on pre-orders.
Efficiency is the big question.
There hasn't been any info on specs and improvements to the tech that I know of besides that the S6 and Edge will support both wireless standards.
I have a Qi pad and slim under the back cover receiver for my S5 and it's not great at all.
It's very slow to charge.
It gets quite hot. I stopped using it mostly for this reason. I can just imagine what that was doing to the halflife of my battery and possibly the other components.
It will often turn the screen on and off when it's fully charged like it's topping up but it thinks it's been removed and put back on the pad.
Hopefully Samsung has gotten it right. I can't imagine them doing it if it has all the same issues as the current aftermarket ones.
If it gets hot. I won't be using wireless charging with an inbuilt battery especially.
At least there is no more cover like on the S5.

Sounds like an issue with either the back, the pad, or Samsung's design. I have 8 of the Nokia DT900 Qi chargers around my house for my Nexus 5 and my girlfriend's Droid Turbo, and they work perfectly fine. Yes, it's slower to charge, but for resting them while watching TV, or when you go to sleep for the night, they're ideal.
The fact that I got 2 of the chargers free, and the other 6 for $40 total from when AT&T blew them out of inventory, I'm quite pleased with it, and it's pretty much a requirement on any phone I buy in the future.
wireless charging is more or less useless and overrated. why? SLOW. if you think you"ll be able to throw it on a pad and get 50% charge in less than 30 mins you're going to be disappointed. if the phone takes (for example) 2 hours to charge via usb cable, it will take at least double that when charging via wireless. And as mentioned, not only that, but a lot of heat generated putting unnecessary heat on the battery - even worse now, is the battery cannot be replaced!
when the hp touchpad tablet came out several years ago, i spent like 70 dollars on the wireless dock and only used it twice.
if i can get a wireless pad for free, cool, but i wont be buying one.
save that money and buy a portable battery charger.. you'll be glad you did.

* useless for YOU.
I on the other hand use it regularly, and won't buy a phone without the feature.
Is very convenient for overnight charging with no cable fuss. Also have a wireless charger on my desk at work, and it is great to just toss the phone on it.
Now, does anybody have any experience with both charging variants? From what I have read around, it seems like PMA might be faster with less heat. Meanwhile, Qi has more options for chargers. (I have 3 of them, 2 for the house, 1 for the car).
Wow... it's gonna pricey as shiz!!! $60!
$59 is Canadian. It's also a carrier's suggested retail and far from official.

maybe read this http://gizmodo.com/how-to-take-care-of-your-smartphone-battery-the-right-w-513217256
and as i was saying:
Avoid wireless charging
Wireless charging can be incredibly convenient if your phone can do it, but it's not without its disadvantages. The inductive, wireless chargers out there today have this nasty habit of generating a fair bit of waste heat. And while wasted energy is just a bummer in general, that heat will also toast your battery in the process. That's no bueno. It's a little less convenient, but standard plug-in charging is going to keep your battery in better shape, especially if you're some place warm to begin with.

and:
You don't want to have battery charging constantly either; lithium-ion batteries can get overheated. Luckily for you, your charger is smart enough to help with this, and will cut your phone off for a spell once it's full. And to complicate matters a even further, your battery doesn't particularly like being all the way full either. In fact, your battery will behave the best if you take it off the charge before it hits 100 percent, and leaving it plugged when it's already full is going to cause a little degradation.

have fun degrading your internal sealed battery. especially with overnight charging for many hours.
this is the reason i find wireless chargers 'useless', maybe without these issues (mostly heat) and if the battery could be easily replaced i wouldn't mind using one. more of a reason that it's kinds of useless. it takes 1 more seconds to plug the phone in if charging overnight. it's not worth the extra wear they put on your battery.

I only keep phones 6-12 months, so I'm not real worried about battery longevity.
But thanks for your concern. Probably valid points in terms of longevity. From a safety standpoint it is fine.
Hi, I would like to ask you, what is your experience with that cheap S4 Qi receiver pads (for example from ebay...). Is it charging fast? How much is cover bulged? Is it dangerous for the battery?
Thank you very much for sharing your experience.
It does make the back cover bulge a bit but it's not bad.
The phone gets warm when charging wirelessly but it's not too bad at all.
Sometimes, the charging pad will detect the receiver but the phone doesn't charge. If I remove the phone from the charging pad for a few minutes and put it back, it will start to charge.
Charging wirelessly is not as fast as using a wired charger and I would say it takes about 30 to 50 percent longer.

Thank you for response. Is NFC working with that Qi pad?
I have never used nfc on my phone but I know you can get pads that do support nfc as an option.
Hi there
I have a qi receiver on the S4. My one has input: "self-adaptation" (whatever that means) and an output of 600mah. It charges at a decent speed. I use the LG G3 wireless charger and a few other wireless charging pads and they seem to charge at a decent speed. A full charge takes about 3 hours.
The cover does bulge a tiny bit, but it is barely noticeable trust me- definitely worth it.
The phone only gets a little warmer- again nothing to worry about for sure.
I am certain that it doesn't do any damage to the phone and battery. I have using wireless charging overnight everyday for the past few years on the S4 and nothing has gone wrong. I rarely use cable charging anymore
I recommend getting a qi receiver for the S4- it is worth it.
Has anyone found a Qi charging receiver so thin that it doesn't bulge at all?

I have a qi receiver on the S4. My one has input: "self-adaptation" (whatever that means) and an output of 600mah. It charges at a decent speed. I use the LG G3 wireless charger and a few other wireless charging pads and they seem to charge at a decent speed. A full charge takes about 3 hours.
The cover does bulge a tiny bit, but it is barely noticeable trust me- definitely worth it.
The phone only gets a little warmer- again nothing to worry about for sure.
I am certain that it doesn't do any damage to the phone and battery. I have using wireless charging overnight everyday for the past few years on the S4 and nothing has gone wrong. I rarely use cable charging anymore
I recommend getting a qi receiver for the S4- it is worth it.

Is it today something better what can more than 600 mA ?
Can you recommend something good ?
I can tell you the one from Aukey, although it uses a flat printed circuit coil, bulges a lot. Enough I didn't want to use it. It was advertised as being "ultra slim 0.2mm", but when I measured it with calipers, it's more like 0.9mm. The ferrite pad on it is most of the thickness.
No Bulge

Has anyone found a Qi charging receiver so thin that it doesn't bulge at all?

The Fone Salesman S4 SlimPWRcard does not bulge at all.
Looking for a back cover OR a qi "pad" that fits inside the phone that ALSO takes advantage of fast charging qi. Not the standard rate of wireless charging. Thanks
I haven't seen anything but cheap stuff. Perhaps phone doesn't support fast charging via those contacts on the back. Also I don't see anyone developing such a thing for an outdated phone.
The Note 4 doesn't support Fast Charging on wireless charger. If you do put it on a Wireless Fast Charging pad, it will charge at normal speed. I actually tried this with a Samsung wireless Fast Charging pad and a Samsung Note 4 S-view case made for wireless charging. In order to use wireless charging on the Note 4, you have to have a case or battery cover that supports wireless charging. Or, you can get one of the wireless charging receivers available on Amazon, eBay or elsewhere. I haven't tried one of the receivers, though a friend did. He had mixed luck getting it to charge at regular speed. Apparently not all receivers are made accurately enough to touch the necessary contracts on the case and phone.

S-view case + fast charge pad

How does the combo Fast charge Samsung pad and S-View wireless combo work together? I mean, does it heat up the phone and how fast does it approximately charge? Thanks.
The one of the wireless chargers I use made the phone too hot for my liking. The other one seemed to work fine. Haven't tried the Samsun ones. I had a wireless charging pad initially on the back of my phone, but I popped the back off enough times and it always felt like it was bulging out a little, so gave the old s-view case to a friend, and bought the one where it was integrated. Works great. But yeah, I don't think it supports the fast charging.
I've using this: http://www.ebay.com/itm/301400816942?_trksid=p2060353.m2749.l2649&ssPageName=STRK:MEBIDX:IT, for over a month. I'm using it with a "normal" samsung reciever, it works well, the phone doesn't get too hot, but the charging speed is far from fast charging, so, it is more like a gimmick.

It works well. Not fast, but it also doesn't heat up the phone. That's the reason I got it. I didn't really time it, but I would expect it to charge at the standard 1 Amp/hr. So, about 3-4 hours if the phone was totally dead. I got it because my phone was over-heating with the fast charger that came with it. I got my charger as an open box at my local Microcenter. However, Amazon has them for around $20-50, depending on if it's the Fast charger or the standard one. One thing I would look at carefully is whether the Samsung wireless chargers at Amazon are real OEM Samsung, or fake. The wireless S-view case I got came from Amazon. It was in Samsung retail packaging and sealed. It was around $31.50 and new. Fortunately I got it with Amazon Prime shipping for free shipping. I just checked, though, and the prices have gone up to over $40. There is one for $33-$34. Another possibility is buying the "battery charging system." It is basically a battery charging case, a new battery and a carrying case for your spare battery. I got it from Sprint for around $25 + tax. The shipping was free. You have to use your own charger with it. It seems less likely to overheat. It has been better for me to have the extra battery. I think I mentioned that I had gotten my Note 4 replaced under TEP, as it was over-heating. I think it was that particular phone that hated the first update to MM. OTOH, my replacement Note 4 has been very happy on PG1, which was on it when I got it. I usually make it through the day with a charge left on the battery I started with. I carry my spare in case. It hasn't overheated. I am hesitant to use Fast Charging, if I don't have to. I believe Fast Charging is more apt to overheat the phone and battery, and probably shorten the life of the battery, if not the phone as well.
are all the s-view cases supporting Qi charging? how can I tell if one does before I buy it? how many contact pins will it have?
thanks!
I use the following 3rd party Qi charging back, and although it is a tight fit, it seems to work well and says it supports 650ma output via the charging pins. It also says that it supports s-view function, but I don't have a s-view case to test with.
Again it is a tight fit, but if you put it on from the bottom first, it can be massaged on.
