NFC range with battery case - Samsung Galaxy Note 9 Questions & Answers

Hi,
I have the Mophie Juice Pack (wireless charging enabled battery case). I bought this one because there were a couple of reviews out there saying NFC still worked.
I'm finding that it doesn't work at all with the case on. Which is a big kick to the balls given it cost £100/$100.
Does anyone know of a way to boost the NFC? Either through software or some tinkering with the phone or case?
Thanks
Joe

It's likely that the few reviews you mentioned are paid or simply fake.
A lithium-ion battery is essentially thin metal foils with electrolytes in between. In addition to the metal in the battery, the wireless charger in the case also features a shield on the backside of the charging coil to protect equipment on the other side from interference from the rapidly fluctuating electromagnetic field of the transmitter in your charging pad.
With that much metal, no amount of boosting the power to the NFC antenna will improve reception, just as you won't be able to see through a brick wall simply by beefing up your flashlight.
Sorry.

Thanks. Mophie themselves said the case "could interfere with NFC." There's no "could" or "interfere" about it. It's solidly blocked as you describe.
I've returned it for a refund. Sad really as it really was a nice case. If NFC isn't a deal breaker for anyone I'd solidly recommend it.

[REVIEW] CHOETECH Qi charger and Circle Case w/NFC & Qi

So I was sent The CHOETECH Iron Stand Qi Wireless Charging Pad and the CHOETECH LG G4 Quick Circle Case in White for Review.
http://www.amazon.com/Wireless-Charger-CHOETECH-Charging-Adapter/dp/B010B6PSMC/ref=sr_1_6
http://www.amazon.com/CHOETECH-Wireless-Charger-Charging-Receiver/dp/B011DTIWB0/ref=sr_1_3
Ampere reports it is charging at about 670mA. My keweisi USB detector says it is drawing 4.82volts and 1.31A
The wake/sleep feature works really well and consistently.
It was as simple as removing my old back and snapping this one in.
It fits like stock battery back cover with a flip over flap to protect the face, nice sturdy quality It detects when closed, activating a circle clock, that you can tap to activate other apps to display within the circle and still allowing you to use the phone while closed.
The 3 coil Qi charging stand makes it easy to place, no fiddling for that sweet spot. Can place it up right on laying on its side. Great to use as a dock while watching videos or a a night stand alarm clock.
I should have that quick circle case on the way to review as well. Mind if I just attach my review here when I get mine in and write my review for it?
I would have loved to get that charger! I've been thinking about getting a dock wireless charger. I'm currently using just a flat wireless charging pad from Choetech. It works good, but it's a hassle to make sure my Nexus 7 is aligned currently.

Clockcycle,
Are you still using the "stand" charger? Are you using it with the Artech case you reviewed earlier?
This seems to be something I would be very interested in to simply place my LG G4 on the stand and walk away. If you have tested it with anything other than your Clock case can you elaborate on just how it is doing for you?
Cheers,
Mike
Can you just remove the front circle cover and just use the back cover with the Qi and NFC? Is it easily removable or do you have to cut off the front cover?
Thanks for sharing. Just going to try this one.

You might be able to yank it out or you may need to cut it. It's not a bad idea, either, if you want a slim, snap on case that's wireless charging compatible and you don't want to go the route of manually installing a sticker.
I'll have my review posted for this case either tonight or tomorrow. I've been using it for a week and I finally have some time to sit down with.
Long story short, it's a good case more than worth the price, though the actual functionality of circle view leaves a lot to be desired.

My full review:
Ever since the LG G3 released in 2014 and LG introduced the concept of cases that replaced the standard battery door cover and snapped on in its place, I thought the possibilities would be endless. Sadly, all but the G3 Quick Circle case were limited only to overseas retailers and no third party case maker thought to jump on this idea. With the release of the LG G4, LG reintroduced their Quick Circle case only which was unfortunate since the G3 had other replacement back cases that offered either better grip or more protection while still being a wireless charging option for those who did not want a folio case.
Since the launch of the LG G4, wireless charging has essentially not been an option for the average consumer unless they wanted to pay $60 for the official Quick Circle case (compared to $16 for this CHOETECH knock off which was only recently released). The only option for those of us who wanted wireless charging and actually knew that we had other options was to deal with the headache of tracking down a seller who sold a wireless NCF/Qi sticker and installing it ourselves, with many users reporting just as many failures as successes. Sadly, LG just does a poor job of actually supporting their phones once they're out of the door.
Wireless charging aside, there's not even many quality options for an affordable, quality Quick Circle case and none other that I've seen that actually replace the battery door cover rather than just snapping onto your phone like a standard phone case and adding extra bulk. Out of nowhere, here comes CHOETECH giving consumers an option for wireless charging and a quick circle case in the style of LG's official version. Not only that, maybe there's also hope that we'll see other styles of non-folio, wireless charging cases that similarly replace the battery door cover (fingers crossed).
I don't have an official LG Quick Circle case to compare this one to, but, from comparing photos, it looks exactly the the official case minus the LG branding. I received the black case for my review and, despite it being listed as "black," this case is a gray color. In fact, it's the same exact gray as the standard "Metallic Gray" back that you can purchase the G4 in. They both have the same diamond pattern back, but it's definitely more pronounced with this case. While it's a very subtle feeling with the standard back cover, you can actually easily feel the diamond patterned back on this case and it's actually a kind of cool feeling. Furthermore, I feel like this case is less slippery than the standard back plate, though my girlfriend disagrees with me on that point. The texture of the screen cover has a nice, soft fabric feel to it.
The case fits great. You snap your phone into it just as if you were snapping on your standard back plate so it's minimal bulk. I'd say it offers just as much protection as those slim, plastic cases that you can purchase. That is, it protects the corners of your phone, though the top and bottom remained a bit exposed. In addition to that protection, your screen also has a cover to protect it from scratches except for the open circle. No ports are blocked and there are cutouts for both the LED indicator and front speaker so that you can take calls without opening the cover.
In short, it's a near perfect folio case, though I would have preferred true black to be a color option along with other color choices and maybe even leather varieties.
My main gripe with this case is that there is no real way to keep the cover closed. I wish it had some sort of magnetic clamp to keep it closed. When you first get the case, the flap connecting the cover to the base of the case is a bit rigid so the cover will not stay closed flat on the screen without some effort on your part, though, after using it for a while, it becomes less of a nuisance. Still, I would have liked to see some sort of way to keep the cover clasped shut without any thought or effort.
My only other gripes are with the functionality of the quick circle view and its compatible apps and that's no fault of the case. I basically only use the open circle view for viewing the time so I wouldn't mind seeing a variant of this case without the circle opening since it's usually more convenient to just look at your full screen anyway.
I would definitely recommend this case, but not for everybody. If you don't like folio cases, then obviously this isn't the case for you. However, if you're just looking for a way to get wireless charging onto your phone and you really don't like folio cases, you could always pull off or cut the flap that holds the screen cover to your case and just discard it so long as you don't mind that the case is no longer symmetrical. To anyone else that genuinely likes folio cases, is genuinely interested in the circle view function, and would also like to have wireless charging on their phone, then I think you should at least give this case a try. It's cheap and it feels great without adding extra bulk to your phone.

I bought this case and stand for my lg g4 a month ago and it works perfectly to charger the phone, when my battery is at 100% the charger enters standby mode. And this is where the problem starts for me; the charger will not start again when I need to charge my LG G4.
I need to reconnect the power source for the charger and than it works again, hence the reason for a qi charger is lost.
Do you experience the same problem with the choetech standing qi charger?
I've been in contact with choetech and recived a new case, but its still the same problem. They will send a replacement chargee, but I figure I ask here first if you experienced the same problem.

Heat issues with wireless charging?

I dug around in here, and haven't found a thread discussing this particular issue, so I'm starting one to discuss with anyone who's interested. I recently found a decent deal for a plastic battery cover with a qi sticker included on Amazon (from China) for $20, so I tried it out. (http://www.amazon.com/gp/product/B014KQXR4A?psc=1&redirect=true&ref_=oh_aui_detailpage_o09_s00) While the battery cover is really high quality (and honestly is worth the $20 alone), and I was able to get it to charge successfully on 2 out of my 3 wireless chargers, the phone gets REALLY hot while charging. It sits at around 40-41 degrees celcius while charging. And it doesn't cool down much after reaching 100%. It lowers a little bit, but still sits at around 35 degrees celcius while just maintaining 100% charge. I would really love to be able to let it just sit on my desk all day while maintaining 100% charge, but am really concerned with the heat shortening the lifespan of the phone.
If shortening the lifespan of the phone were my only issue, I guess I could live with it. But yesterday it got so hot that the phone froze up entirely, and I had to remove the battery to reboot it. And when it came back up, the wallpaper was changed, which I found was odd.
So I'd like to hear reports from others who have purchased qi stickers or backs, and see a link to the particular part, and how it has fared in the heat department. I'm curious to know if it's just this qi sticker, or if wireless charging on these phones will heat them up like this no matter which sticker is used. Wondering if LG just couldn't get it to function without heating up, and that's why they decided not to include it from the factory. Including a poll, not sure how informative it will be.
Thanks in advance for your input.
P.S. For anyone wondering why I didn't just purchase a qi sticker instead of the whole back and everything, two reasons. First, I got the leather back, which I really don't like, and have had my eyes out for a cheap plastic back replacement, even offering to swap my leather back for someone elses plastic back. The leather doesn't fit all the cases I like, and seems like it's going to start showing bad wear and tear. Second, I was hoping to not have to fit the sticker myself, was hoping for an out of the box solution. However, that was screwed when the back I bought came with the sticker not installed anyway lol.
Edit: Just realized I should have made the poll multiple choice since I added the freezes or crashes option. Oops.
I purchased the entire gambit: circle case, generic QI sticker and Newisdom upgraded chip. I had minimal issues with the circle case but ultimately I just didn't like how it fit so I went with the generic QI. On my Itian charger I have no issues what so ever, I bought a Captain America Qi charger on eBay for $10 and it will charge for a little while and then overheat the phone and charger.
Truthfully I've had nothing but problems with the Newisdom sticker, especially with Spigen case, I regret purchasing it. My generic one works pretty flawlessly regardless of the scenarios.
I think at the end of the day what matters most is the charger, a good charger works pretty seamlessly.
Thanks!
Wireless charging any phone will get it hot or warm. That's the downside of wireless charging.

Thanks for the input. I've got three fairly decent chargers, and it gets hot on all of them. While the Galaxy S3's we have only get slightly warm while charging, and completely while maintaining. And they have decent $10 coil stickers in them.

This is not true, at least for OEM phones. I know the Galaxy S6 which has qi charging built in doesn't get warm at all. And the two Galaxy S3's we have which had qi capability, but we had to add qi coil stickers to them, only get slightly warm while charging, not even close to what my G4 gets to. And completely cool while maintaining. And I would be totally fine if it got a bit warm while charging. It is kind of to be expected. But my phone is not just getting warm. It's getting HOT. Really hot. And it doesn't cool down much while maintaining.
Way to hot
I recently bought a qi wireless charging pad from a major store will at work for my galaxy s7, first morning phone real hot and battery 0% life. Thought I had did something wrong. 2nd morning woke up late and grabbed phone and threw it because it was burning hand, stunk like burned electronics and was steaming. It had zero battery and was about 50 when laid on it. Dealing with manufacture now and trying to get my phone fixed or repaired. 2 months old and never an issue with heat even with fast charge. Anybody have this issue? If it was on longer I know it would of melted or who knows.
mines get hot around 43 celcious. or less i havent use it in a while as weather here its still hot.

Review: Zerolemon 5500mah Note 8 Battery Case

First, I did receive a review sample from ZeroLemon.
If you're looking for a slim solution, this is NOT your choice, if you're looking for massive amounts of additional power on the go without having to carry a cable and external battery, then this IS your solution.
As I'm sure everyone will mention, it's LARGE. Until battery tech gets smaller, you gotta cram that battery somewhere. It's pretty hefty as well. If you wanted with this battery pack, you could outlast everyone around you in a marathon Pokemon Go session, long flights of movies won't be a problem. It's not going to provide any screen protection if dropped, but it might give you some arm workouts as you use the phone.
It's brainless to use. Plug your Note 8 into the battery case. All the button passthru's worked fine and aligned up. You are still "capable" of using the fingerprint reader, expect a bit more "reach" to get there. The case itself doesn't block the camera at all. No ghosting of the case in your photos.
If I were designing this, I would have added a flipout kickstand so you could just sit and watch movies without having to hold the bulk.
Product Packaging:
Packaging is quite simple, it’s a white ziplock bag and a brown cardboard box. There isn’t much in terms of instructions, just a small flip out pamphlet that instructs you on how to plug in the battery and case.
The battery attaches to the Note 8 via the USB-C port on the phone. The battery attachment also charges through a USB-C female port, so there is no need to change chargers or cables that you are already using with the phone.
Battery Usage:
I charged the case for approximately 12 hours before initial use – as instructed on the white ziplock bag that it all comes in.
The battery/case:
It’s a simple TPU case. It has a matte texture that feels good in the hands and prevents slippage.
After testing the battery case with the camera flash, I found no issues.
There is no need to remove the phone from the attachment in order to transfer files to your computer – something that is not possible with another extended battery case I tried using prior to this one.
Charging:
The battery itself does not support fast charging from the battery to the Note 8, but it does allow for pass through quick charging of your phone if you connect the battery case to your Samsung fast charger.
Pros:
Good extended capacity
Power on/off button
Solid construction of battery and case
Pass-through quick charging
Data transfer pass-through
Worked first time. Living up to name ZeroLemon.
Case itself is grippy and comfortable
Cons:
No NFC
No QI charging
Recessed fingerprint reader
Noticeable increase in weight and thickness of the phone
Needs a flip out kickstand.
Interestingly, if you try to go to the product page its a page saying "Oops - We couldn't find that one"

Interesting that they make two of them now. I wonder how much thinner the 5500 will be compared to the 10000 one.
I saw that 5500 version a few weeks ago before the 10,000 mah one was listed and didn't like the way it looked. The 10,000mah one looks decent, I need to know if it will work with the Whitestone Dome though.
When you are charging this, does the phone and the case get charged in parallel? Or the phone first, then the case etc.
Also how long does it take to charge the case itself, with the phone in it?

I like mine. It's a little smaller and the case is refreshed from older models I've used from ZL

Well I went thru 2 10000 cases in 1 week and both failed. Then I bought this slim one. Worked great for 2 charges and then would not take charge from factory charger. Will only charge from pc. Contacted zerolemon and was told must be defective cable. Lol. Yet charges my phone properly. Zerolemon is garbage and I recommend everyone to stay away from it. Last 2 phones product has gone to worthless in less then 2 weeks.
All their 5500 seems to be is a rebranded knockoff of the ebay versions for about $20 more. The 10 000 version looks like there's. Bottom line, like the OP said. It's heavy, no wireless charging, no magnet, no nfc. Those three are a killer, I regret not waiting for mophie's more expensive alternative.
The Mophie one is only 2950mAh and can only charge the phone 50% of juice.

Sorry I don't have it. I want to purchase it but it is currently out of stock.
It should be smaller in size than zerolemon as it has smaller capacity, I think.

ZeroLemon Note 8 10,000mah battery case combo

First off, let me say this is a great setup for a power user and is the third ZeroLemon 10000mah battery case I have used on a mobile device. I use my phone for everyday business and multimedia use around 12-13 hours a day. I am constantly in the car or traveling for clients and have very little time to actively charge my phone on the move. This battery case combo was a no brainer for me.
So far I have been through 5 complete charge/drain cycles. Charging this battery case usually takes 8-10+ hours and holds a charge pretty well from what I have tested throughout the week.
The overall size and feel is great, although it does take a beautiful thin phone and make it into a hefty brick. I would say it is relatively the same size as 3 Note 8 phones stacked on top of each other. For me, this feels great and gives me a bit more piece of mind when handling the phone all day. However, your basic consumer may not like trade-off. That though, is a positive trade-off for me to have stellar battery and usability to get me through the day, worry free.
The case fits the phone very well and I do not worry about it coming loose, shifting etc...If I were to drop it I don't know how well it would absorb the impact, or whether the phone would stay in the case itsself. I'm not going to test that though. The s-pen can be a bit difficult to get out/in. This isn't an issue for me as I rarely use this feature. All the buttons line up with the respective case buttons and pluggin in the charger has ample clearances etc. The camera and fingerprint sensor are easily reachable as well.
Overall, this was a great purchase and one I will make again for future devices. It does exactly what I need it to do every day, and it does it very well.

I don't think anyone could have designed an uglier solution
Way too much bulk to add considering how long the battery last and how fast the Note 8 charges. I have an external battery, but have only used it once
I bought the 10000 mah lemon battery as well via pre-order being I was coming off a rooted Note 3. Once I seen they was making a 10000 mah lemon I went and bought the Note 8 immediately. Not only have I've gotten 3-4 days with moderate use but it can also be used as an EXTERNAL battery for anyone worried about the added bulk or having to take a more protective designed case off to use the lemon case and battery.
I haven't even seen this option advertised in the Amazon reviews, Zero Lemon website or anywhere so decided to share. Basically just buy any USB C to USB C cable like this but shorter if you want "AmazonBasics USB Type-C to USB Type-C 2.0 Cable - 6 Feet (1.8 M... https://www.amazon.com/dp/B01GGKZ1VA/ref=cm_sw_r_sms_awdo_t1_icXvAb4CR5EGC and plug it in the actual white and black battery that fits in the lemon case. There's a input and output insert. Use the Input slot and plug the other end into the Note 8.
This works just like an external battery where you get the option to have it in the case or out the case. Also to add. When flat on a table, the lip for the case slightly raises the phone off flat surface which helps with the glass not touching. Although it's not designed to protect the phone I dropped mines twice off a dresser and not a scratch. Landed on its back possibly because of the weight. Hope this helps anyone in deciding.

Ohsnap! Grip

I backed this on Indiegogo back when I was your age. I recieved mine about a week ago and I love it. It's like a pop socket but way better. It's a good grip and kickstand with a few angles. They are being sold directly from ohsnap.com now. I don't know if they'll be available on Amazon or anywhere else. I currently have mine stuck to a thin tpu case. Still works with wireless charging if the case is thin enough. The grip itself is magnetic. I like sticking my phone to my fridge while I cook. I recommend you check it out.

That's great news , thanks for sharing .
I really, really wanted to like this.
BUT, no matter where I place it, I cannot use any of samsung's wireless chargers and I really don't want to get their specific charger and find out that the metal ring blocks it too.
Looks cheap! I wouldn't put that on my phone! That's my beef with PopSockets is they make your premium phone look cheap!

It's actually very well designed. Just the metal ring and/or magnets block the wireless charging.

I've actually only used the Snapcharge that you can buy with this, so I'm uncertain if it works with other wireless chargers. The makers say it will do I was inclined to believe it. I don't think it looks cheap at all and I have the plastic version. There is also the Luxe version, which is made out of aluminum. My biggest problem with pop sockets were that they did not just slide into your pocket, but this slides into my pocket with ease.
Negative and positive
So it works on "most" wireless chargers but Samsung and some other chargers have a "protection" of sorts in case they feel interference. This causes wireless charging to pause/stop. Ironically the cheap fast wireless chargers that don't have this work fine.
I have 2 of the OnSnap - the regular and the LUXE.
If you use a lot of Samsung wireless chargers don't waste your money because it wont work no matter which way you place it or where on the body of the phone you place it.
The only exception would be if you have a case and are ok with taking the case off to allow wireless charging through the SAMSUNG Wireless chargers or the like (not bad counting on the case)
If you have a naked phone (no case) it counts on your wireless charger set up. Because once the ring is on there is no taking it off and then putting it back on as the metal ring is meant to stay on. The rest of the OhSnap is meant to well snap off if you need to and it just reattaches without issue to the metal ring.
Most non-Samsung wireless chargers worked but it will be a hit and miss since there's so many out there but I would say there's more on the working side then on non-working side.
But biggest take away is Don't plan for this to work with Samsung chargers.
They don't ship this grip outside of US... Is there any way to buy it if you're from Europe?
If no, is there an alternative grip?
