Most places are declining to make this
We need moto to make these kinda features stock
The problem is the phone is not designed to be opened or the battery removed.. hence voiding warranty if u do so
That's why we prob won't see this for the RAZR HD and HD maxx
With the s3 u can just pop the back door off...this phone I have yet to see a breakdown... I really doubt the aftermarket companies that make those kinda product will want to invest in making a product that voids ur warranty just to install it

This is xda surely warranties aren't a concern? If i saw a tear down it wouldn't be hard to set it up with a touch stone like the s3 i would think?

Not even worth trying, I attempted this mod on the Atrix HD which is done by connecting the positive terminal on the palm pixi to the +5v part on phone and it eventually worked but a usb had to be plugged into phone the usb wasnt plugged into anything but the phone wouldnt charge unless it actually detected a usb plugged in.
Unfortunately, I don't think it will happen. It is true that XDA doesn't care too much about warranties, but there is a big difference between hardware and software warranties. Accessory manufacturers aren't going to make something that you have to hack apart your phone for. What is worth more to you, a 30 dollar wireless charging accessory that you have to jimmy rig, or the warranty that protects your $650 investment? You can unroot easy enough to return to VZW but try explaning the wireless charging mod that's on there now.
I've been interested in getting a wireless charging solution for my phone, and while I have to look into it a bit more to figure out specifics for certain things, I think it may be possible to create a case that plugs into the USB port so we wouldn't void our warranties.
Designing the case wont bee too much hassle, a micrometer and some 3D modeling software. However we need to find a way to get a micro usb connector that has a 90 degree bend in it to go into the port without causing any sort of scraping. Possibly have the right hand side of the case hinged and secured by snaps on top and bottom? or have the connector itself removable.
So materials for a test setup would require:
Touchstone components
90 degree MicroUSB male connector
Soldering gun
Custom case
I don't have the setup to do this available to me right now, however I think the biggest problem would be getting a connector small enough to keep from adding a lot of bulk to the side of the phone. Heck, with it only supplying .42 A at about 4.8 volts, it may not be inconceivable to group 2 in a case for faster charging. I haven't worked with the touchstone charger myself before, so I don't know their size.
Anyways, food for thought, and a possible personal project once I get some more important things finished up.
Hi,
Signed up just to post my results so far.
Ive gotten razr HD maxx to charge through the USB port using a touchstone pixi back cover.
It works using the touchstone charging base but the usb wall wart that came with the razr hd. The amperage coming though was not enough using a motorola dedicated usb wall charger that came with my bluetooth headphones putting out 500mA. It charges a little slower using the induction charger. I need to figure out if this will work running off my cars electrical system as that is my main motivation for getting this to work.
To get the phone to go into charging mode you have to either short out the USB data wires or connect the D+ wire to a 2v contact on the touchstone pixi circuit. Connecting the usb D+ to the 2v contact hopefully will allow me to hardwire this setup directly to the phone and leave the usb port free if, assuming I can find enough room inside for everything.
The phone is charging right now on the touchstone base, estimate 2hr to full charge from 70%
Im going to try and shove it all inside the phone tomorrow.

I dont know if I can get this to work internally now due to soldeirng limitations.
There is just enough space to slightly force the phone back together (it does bulge) but the pins for the USB port are covered and recessed under the USB housing. There is not enough clearance for me to do a clean solder onto the contacts.
I can not find another trace for the 5v or D+ pin on the circuit board.
If i could remove the outer cover maybe but for now this is going to have to be a plug into the USB port/external mod until i either grow a bigger pair and try to remove the USB port or find alternate contacts to solder the leads onto.
EDIT: I actually just went for it and ground off the corner of the USB casing. And actually soldered the wires onto the pins. However the touchstone system will not allow this to work internally. The battey when laid on the coil will interfere with the EMF and cause an unstable voltage. It goes from a low of 4.8 to 5.5 v. Maybe someone thats an RF engineer can figure something out with the reflector.
Maybe if i get more motivation later ill check out a qi standard charging setup to see if its compatible. For now im going to find an outer case and just go with the usb plug use this externally.
Try picking up some foil tape and put it between the battery and coil. You should be able to pick some up at your local hardware or hobby shop. It may need to be touching the ground to be effective though. Depending on some things over the next month I might be able to start working on my own setup.
Tried that but no go.
With the foil covering the coil, the voltage fluctuates before the battery is even placed over it. I hope you can get it working internally, ive since used an otterbox commuter case to hold it all together.

In what order are you putting the components? Phone, battery then coil. Or phone coil then battery? Basically is the coil between the hardware and battery, or is the coil between the back panel and battery.
I can see where the issues would arise if it is between the battery and hardware. Both would be giving off EM waves if the device is on. If it is between them, try moving the coil to between the back panel and the battery.
Right now I can't afford to try an internal mod where I could kill the phone if I screw up, so until a couple things settle down for me I will only be attempting an external mod that fits in a case. If I can get the design right I may be able to make it so there is still a USB port available.
*Edit*
I'm sourcing/pricing components right now and you've already given me the voltage output, but how about the current provided by the coil? What I'm planning involves building a small circuit that would short the D+ wire only when there is no USB cable connected.
Anyway we can get some pics of the project in progress?

So I don't have the components at the moment to start my project physically, however as I said I am finding the parts I'll need. Apparently its a PITA to get male micro USB connectors without bulk orders, or importing from China. I'd prefer a SMT (surface mount for circuit boards) but those appear to be next to impossible. Anyways I've been able to find pretty much everything I need and just a matter of time till they get in.
My plan is to provide a clean circuit that would use the USB port on the phone to charge using the coil, while adding a new USB port into a phone case to still allow USB data and charging. However as the coil can create fluctuations in voltage and current, I want to have a setup that allows for it to be isolated while it is plugged in through USB.
Attached is just a quick circuit diagram I made using EveryCircuit, I need to refine it still, but just an example. Heck if you have the app rebuild it and you'll be able to see what it does. Left side is USB cable input, with a switch at top to simulate plugging in and unplugging, while the right is the phone side with the power source being the coil. The light/loads are to simulate the data lines and power lines and show whether the circuit works.
When I get the parts together I'll take pics and post a tutorial. I have some 3D modeling experience so I may even be able to design a custom case to put everything into.

the coil was sandwiched between the back case of the phone and the battery. The metal in the battery is influencing the flux going through the charging coil. The base is not always on, it only turns on when the charging coil is present. If not present the base seems to send out a pulse every so often to detect the presence of the charging coil inside the phone.
The issues arise once the battery is laid across the coil, the base begins to oscillate and the voltage begins to alternate. Also the coils seem to only work within a specific frequency range, but i dont have a signal generator or oscope to confirm this.
According to the battery charging app the base is putting out ~6-700mA to the phone with an 1A charger plugged into the base.
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.

Hey guys, so I'm looking for a case that fits the added bulk of the OEM QI back. Any recommendations? I'm looking at the i-blason case but open to any other suggestions.

"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....
Hi,
After my battery went from full to empty in less than two hours when using a sat nav app yesterday, I need an in-car charger for the dashboard. I have a micro USB one but the flap on the Z3 makes it annoying. So I was wondering if there were any good magnetic adapters?
I have a 2A USB charger for the lighter socket, so I only need either a USB-magnetic cable, or an adapter that will take a micro USB. Ideally one that exits at the bottom of the phone so it can be routed neatly, rather than sideways which will then need to bend round.
Anyone have any recommendations? How about some pics of how you're set up in your car? (I have an airframe+ vent mount coming today)
the X2 magnetic charger (which just clips on any usb cable) on amazon has great reviews, depending on your case or mount you might have to shave off some of the adapter
proclip / brodit (depending on where you are in the world) offers great magnetic mounts and chargers, some need to be professionally installed, however its been stated in reviews that they fit tight so they might not work with cases, especially bulky ones and they have been known to peel up tempered glass screen protectors
I am in the same boat as you, I want a magnetic charging mount for my car and I spent a few hours tuesday researching options to no joy :|
I've used brodit mounts before but I wanted something a little more discreet than a hardwired solution - which is why I went for the Kenu Airframe+
The X2 seems to get good reviews but I'm not sure if it would be frustrating that the cable would come out sideways (as the phone would most likely be in landscape mode). Although many of the satnav apps I'm trying actually work pretty well in portrait..
if you got it horizontal the cable would be out the top or bottom yeah?
I usually keep mine in portrait
you use waze?
probably would be coming out of the bottom of the phone if in landscape.
don't know what I'm using yet - I have about 8 apps installed and I'm trying them out. Some have demo routes which is helpful, but some need me to use them while I'm driving to test so it'll take a while to settle on one.
I quite like tom tom's look and feel as I'm familiar with their standalone devices, and copilot seems good too. Haven't tried waze or google maps navigation yet, they're next.
yeah waze is killer, my CO recommended it and ive been hooked since
Its 95% effective when spotting speed traps and errs on the side of caution (sometimes cops wont be there, moved along, already pulled someone over), gives reports on potholes, construction ahead, real time traffic, speed traps, stopped cars, etc. its amazing, my friends and I are blown away.
its only difficulty is when you don't give it a direct address, it can have troubles searching for a restaurant or some such but if you have the street name you're set

proclip / brodit (depending on where you are in the world) offers great magnetic mounts and chargers, some need to be professionally installed, however its been stated in reviews that they fit tight so they might not work with cases, especially bulky ones and they have been known to peel up tempered glass screen protectors
I am in the same boat as you, I want a magnetic charging mount for my car and I spent a few hours tuesday researching options to no joy :|

I have an X2 adapter, it's great, BUT it is not strong enough to be secure when under the device. The torque of the cable will cause it to come off when above the device too.
Using a thinner-gauge cbale might help, but then the voltage drop will be too great to keep the battery from discharging.
My personal favorite has been:
Right-angle MicroUSB (this makes a HUGE difference in convenience on the Sony devices, since the cable goes to the right instead of straight down from the mount) - http://www.amazon.com/StarTech-com-Micro-USB-Cable-UUSBHAUB3RA/dp/B001AR4NC8/
Quick charge 2.0 car charger - http://www.amazon.com/Powermod-Charge-Certified--Vehicle-Charger/dp/B00P9UILUM/ - The StarTech cables are fairly thin gauge, so drop too much voltage when charging at 5v/2A to keep the phone charged during Navigation. QC2.0 chargers supply the Z3 with 9v, so the same wattage requires less current, and hence less voltage drop through the cable. (same reason long-distance power lines run in the hundreds of kilovolts...)
Does quick charge work through the magnetic port, or you mean you use the USB Port?

I use the USB port, the magnetic port is too unreliable for a vehicle. The thin-gauge right-angle cables make using the USB port MUCH less of a hassle, but they need QC2.0 for proper charging through such a thin cable. (too much voltage drop for high-power standard-voltage charging)
First of all I would like to thank Meenova for being as kind as to send me out some items to test out, and I would also like to take this opportunity to say this is not sponsored.
The first item Meenova sent me out was a USB Charge Current & Voltage Meter. In all honesty, I don't actually know how to use one of these. The product they sent out appears to do its job of viewing the current and voltage running through it, and it seems rather well built and very sturdy. If you know how to use one and are interested in one you can find one here.
The next item I was sent was a USB 2.0 Hub with Micro USB Charging Ports. Again, it is a really well built product and very sturdy. One of the best features of this product is the two micro USB ports on each side of the hub, if you have products what are able to sit on these hubs (like the Z5 can) you can use the device as a charging stand. Another wonderful feature of this device is that it has 2 USB type A charging ports on it, so it effectively adds another USB port to your computer (if you use it for this function). All 4 of the ports/hubs on the device charge devices what are connected to them too, so it is handy for charging 4 devices at once if you need to. It is a nice and compact product (roughly 2cm x 4.5cm x 0.75cm) so it really doesn't take up much space on the desk. The device also has a little LED on the side of it what allows for the user to see if and when the unit is receiving power (good for troubleshooting faulty computer USB ports and Mains charging adapters). If you are interested in picking one of these devices up for yourself you can find one here.
The next item, which is one of my favourite accessories I've ever used, is the Smart & Secure Fast Charging Adapter. This little piece of kit can also be referred to as a "USB Condom". The basis of this device is to act as a barrier between your (or any) computer and block any data transfer and only allowing charging. The device does it job wonderfully, especially if you use a USB cable to charge your phone on external computers (like employers or school computers), I haven't had any problems with any cables connecting to it, and it functions really well for charging a PS4 controller and not having the PC detect input from it (via DS4Windows). Also I have not noticed any drop in USB charging speeds while using this little piece of kit while using my Aukey QC 2.0 charging cable. The size of the device is really nice too as it is about the size of a USB memory drive and comes with a nice little rubber case to attach it to your keys. If you are interested in one of these (especially to stop people snooping on your personal files while charging) you can pick one up from here.
The final item I received was a Smart & secure Fast Charging Micro USB Cable. Again, such a wonderful piece of kit and it does its job extremely well. It has 2 main functions, the first is regular charging and data synchronization, and the second is only charging. The latter is achieved by having the functions of the previous product embedded into the side of the cable which plugs into the computer and you can switch between the two functions using a switch (also embedded into the side of the cable what plugs into the computer). There is also a little LED on the cable to indicate which function is active, green indicates that the secure charging only mode is active, while red indicates that the charging and data sync is active. Again, I have noticed no drops in charging speed whilst using this piece of kit, nor have I noticed any drops in speeds of data transfer. The length of the device is 1 meter (3.3 feet). The cable is covered with Nylon fabric to help prevent the cable tangling, and it appears to do this really well by kinking the cable so it can be pulled out really easily. If you are interested in one of these you can pick one up from here.
The customer support from Meenova is absolutely wonderful and they are really polite and helpful, one of the best support teams I've had to deal with. All in all I am extremely happy with the products they have supplied and would definitely recommend them.
I've been using magnetic cables for my Android phones for years. You put the magnetic USB adapter in the charging port of the phone and the USB cable connects magnetically to it. Makes it very easy to charge your phone while driving, keeps dust and dirt out of the charging port and decreasing the wear and tear on the port from constantly unplugging and plugging in a cable. However, when the USB adapter that stays inserted into the phones USB port is in there for a certain period of time, it seems like maybe around 5 to 8 hours, it triggers samsungs moisture/foreign object sensor and disables the charging port entirely and the only way to charge is by using a wireless charger. There are several ways to temporarily circumvent this but ultimately the sensor always gets triggered and the song and dance starts over and over again.
So that being said, has anyone figured out how to stopped this from happening without rooting? I love my magnetic charging cables and have invested a lot of money in them and I use them not just for my phone but for several other devices likes tablets and stuff because they can universally fit usb-c, micro, nano and thunderbolt with just one cable.
Thanks!

Did you try with another magnetic adaptor?
I have also been charging with a magnetic charger for many years, now even for the device I've been waiting for almost a month, I ordered brand new kits. I really hope there is no problem like what you described.
Of course I will also buy a wireless charger, but the convenience of using the magnetic one is indispensable for me.
Yeah I'm having the same issue with my magnetic charging cable. I haven't had the phone long enough to see how big of a problem its going to be, When i get the pop up i take the plug tip out for a while and it seems to go away.
Worse comes to worse if it starts to become a major hassle I'll just get a wireless charger hopefully someone will figure out a solid fix before it comes to that
Never knew something like this even existed... Can one leave the tip in the usb port permanently as a cover to protect it from dust/ debris when not using to charge it? It also seems like a great solution for protecting the USB port from the constant wear and tear of plugging/ unplugging into it..
Exactly.
For years I have been using this solution to charge with a magnetic charger and the magnetic adaptor from the cable stays in the phone until I replace the device with another.

I have two brands. Both have the issue.

Yes.
So I tried something that might have fixed it more permanently. See if this works for anyone.
1. When you have the moisture sensor/foreign object notification and you get the message pop-up stating the charging port has been disabled while trying to charge with a cable plugged in, keep the cable plugged into the phone.
2. Then, restart the phone by pressing and holding power and volume down button and selecting restart.
3. When the phone reboots you will notice that the phone is now charging properly. AND if you unplug and plug the cable there is no moisture notification anymore.
I've tested this for about 24 hours and this has been the longest time it's been without triggering the moisture notification. Normally it takes under 8 hours to trigger.
So if this works then you can keep your magnetic adapter inside the phones charging port indefinitely without getting that moisture notification. I have not tried removing and reinstalling the magnetic adapter which might reset the moisture trigger.
Pulling the adaptor and reinstalling it also seems to at least temporarily reset the moisture notice
I'm glad to find out that I'm not the only one with this trouble. I'm not sure what I did, if anything, to fix/workaround the issue, but I've not seen the moisture sensor trigger for almost 3 days now. (Knock on wood.)
Things I've tried:
Reboot while the charger is connected.
Clear data in the USBSettings system app.
Switch to a magnetic plug that hasn't been used before. (I had several that came with the cables that have remained in the box until now.)
After trying each of these at least twice the problem still occurred again later. Today I realized that it's been a few days since it happened. To clear the warning sometimes it takes a blast of compressed air into the port, sometimes it only takes removing the plug, waiting a moment for the notification to clear and then putting it back in.
BTW, for the curious who haven't seen these before, search for "NetDot Gen12" at Amazon. They are very convenient. This is the 3rd or 4th phone I've used them on, and I also use them on tablets and other devices with a USB charging port. The only issue I've seen besides the moisture sensor on the S22U is that there is a small area on the screen next to the magnet where it is a little less sensitive to the s-pen. It's so small and usually such a non-issue that I didn't realize that it was due to the magnet until recently.
Of course, now that I've mentioned that it's been a few days since the moisture sensor was tripped, it has now happened again and my 3 day streak has ended. :-(
I wonder if the true quality of these cables is being revealed through other means (bugs in hardware through environmental discharge or whatever). Could be something simple like ESD on the pins, crosstalk/interference. Either way it's reading a short to ground and doing its job by protecting the phone.
USB was never designed around these magnetic devices and aren't in spec. It's not a phone problem. It's a cable problem.
There's a comment here: https://us.community.samsung.com/t5...lse-moisture-debris-alert-issues/td-p/2204054 that suggests it may be a software issue, as the commenter states that he's started getting it on the Note 10+.

Out of all the Android phones I've used with a magnetic cable (which have been probably 5 from various manufacturers over the years) I've never seen this problem before until now. The last Samsung phone I used was an S7 and I do remember having some odd over heating warnings when charging but eventually that problem went away. I think this "foreign object" sensor is being triggered because the magnetic adapter is staying plugged into the usb-c port in the phone but not charging. Thus the sensor is being triggered. However, there seems to be the same pop-up notification message for "moisture detected" and "foreign object detected" since it covers both in the same message. So it is a little tedious to figure out if the moisture sensor is being triggered or the foreign object sensor is being triggered.
Could the cable be at fault? I highly doubt it at least in my experience. It's more realistic that Samsung has placed so many safety sensors on this phone that it's only a matter of time before one gets triggered. But magnetic cables have been around for years and Samsung knows this. So they knew by installing this foreign object sensor that it might break the use of magnetic cables. Which is sad because Apple has had magnetic charging cables for years in their laptops and recently their Apple phones use magsafe wireless chargers which is a magnet built into the phone.
I've also used magnetic chargers for years in my Android phones and tablets and I've never seen it adversely affect it in any way.
I'm having the same issues and I'm not using some cheap knock-off magnetic cable but one that has been on the market almost 3 years, is still available, comes with a 10yr warranty and supports up to QC4.0 on the mobile cable version (which I have) and is also available in a 100w PD version (ChargeASAP Uno cable). These moisture/debris alerts are the FIRST problem I have EVER had with this magnetic cable, and while I originally bought 3 sets (thinking they would wear out from daily use, I never even opened my 2nd & 3rd set until I started having issues with it in my S22 Ultra on day 1 and assumed it was coincidence that moving it from my previous S10+ to this phone exposed a weakness from wear and/or age. Unfortunately the brand new set had the exact same issue.
Now, in my case, I always wirelessly charge, except when I'm in my car using android auto daily (why I bought the magnetic cable) and the once a month or so I copy data to/from a PC. I am getting the moisture/debris alerts every couple hours or more when the magnetic adapter is in and it is HOURS before or after I actually used the magnetic cable (tip was inserted 24/7 until I got tired of this nightmare). On the weekends when I may not drive or sync for 24-48hrs, I've gotten the warning when the phone was just sitting on a table at the lock screen for an extended period in my house. My charge port is spotless without a speck of dust and this continued to happen with a brand new magnetic charging tip that was sealed in an anti-static bag before putting it in the phone. Honestly this MUST be an erroneous BS error and Samsung should address it.

"Mobile Device" 18w version (I have these): https://chargeasap.com/collections/usb-c-mobile-device-magnetic-cable
They also sell 100w versions geared toward laptops and/or PD Charging
Interesting thread. I never knew about the magnetic system. I do keep a usb-c plug in the port full time to keep out dirt and lint. Never had the moisture popup so far in a week with one inserted in my S22.

This is interesting. So you use just a plastic usb-c insert cover of sorts? Can you provide a link to the product?

There are other versions but these are the last ones I bought: https://www.amazon.com/gp/product/B085T5L9T6/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1
They don't last a long time if you are taking them out every night to charge with a cord. But now that I have wireless charging, they should be more permanent.
