Save Note7 from potential exploding!
1. "Inportant" Disable fast charging under battery settings ( there is toggle to turn off)
2. Use OEM wall charger with OEM cable
3. Before charging phone close all active aplications and clear cashe
4. Before charging turn off wifi, bluetoth,nfc etc..
5.DO NOT CHARGE phone ubder pillow or in bad
Hope this tips help you guys and me
Perhaps we should also all be taking acupuncture and subscribing to new age homeopathy therapies? :silly:
If the battery wants to 'go bang' it will, no options will change that fact.
i'll just take my chances ?

I think switching off fast charging would make a difference. Ad for the rest? Not sure.

It doesn't, otherwise we would have been advised to turn it off by Samsung before the handset is replaced. Or a software update disabling the feature would have been pushed.

Samsung didn't say a word what to do untill replace, but if you read about fast charging, there says " your device will charge quickly but may become hot"
It's got nothing to do with fast charging, it's a fault in the battery that will heat up and catch fire if you're fast charging or not....

See the post above mine
bottom line dont do anything that cause the phone to get too hot for long period of time.

I think a lot of people are concluding that heat is the issue and will create the battery problem. I can't see any evidence that heat causes the battery fault to occur.
Well exploding battery will cause heat.... sooo XD... There probably many other component that cause it but anyone willing to force the note7"C4" to explode?
its a battery fault - the battery cells which are affecting the units are drawing too much power from the mains which in turn heats the battery past limit. i've had mine for about 4 days in the UK and three have told me "no recall or safety instructions have been given by company"
and samsung support have said "none of the problems has occured in the UK so you are fine to use and if it gets hot close all apps and place phone in cool place away from direct sunlight"
but samsung did say they were replacing phones. left details and call back will be in 7days
was on hold for 1 hour waiting for them to answer. might be quicker popping into a samsung store and asking about it.
but if people in UK need a piece of mind and wants to ring samsung the phone number to use is 0330 726 1000 *****THIS IS FOR UK RESIDENTS ONLY*****

I got a phone call from O2 earlier offering me to return the phone for a full refund or a partial refund with a different handset.
the option they didn't advise was to hold onto the phone and they will replace them when they get the new stock, they said this has been the most popular option with the majority of people opting for it, but they also said should the phone show any signs of the problem (getting hot when charging or swelling) I can take the phone in at any time for a refund.
chances are 3 just doesn't have all the info yet, but the recall is every phone, Samsung is probably still communicating with suppliers so it is likely a case of the firms are still learning then they will have to work out how to pass on the information to those affected.
I would have to say it's fast charging...or generic adapters. Because I used the original cable with a generic adapter and after charging for some time, the phone was extremely hot. As in ive never felt any phone become that hot. This was maybe in the first few days I got the phone. I saw fast charging was on so I turned that off.
I stopped using that particular adapter as well (which works for all our other Samsung and apple phones and pads) ... And it never became hot again.
I use another non branded adapter with a non Samsung cable in the office to charge and it doesn't get hot there. Doesn't get hot with my non branded car charger as well.
So my guess is it's the fast charging option. Or just that particular adapter. But so far... Fast charging off... With different adapters and cables.. And it's working fine.. And cool
the problem is 100% in the battery, nothing else in the phone is at fault.
basically when they make a battery it is done with layers of material and a catalyst (acid or similar) inside the battery is compartmented, if 2 of these compartments manage to interact with each other due to a fault in the separator you get a runaway reaction, at best you get a bit swelling or a hot battery, worst case it goes critical and fails (goes pop)
if you have a phone with a faulty battery you can play it safe and turn off options such as fast charging, but the fact is if the battery is one of the few faulty batteries in the wild you are only delaying the inevitable.
the only way to protect the phone is to monitor it carefully while it is charging as if the battery is faulty no amount of changing settings will solve the problem as if that was the case they would have released emergency firmwares by now to minimise risk.
but even then when the phone gets warm it isn't always the battery, my battery normally sits around 30-35C (even while charging) but my phone sometimes feels warm but the problem is the CPU running some times at 50-60C making the phone feel warm and not the actual battery.

Hello, I would like to start off by saying I'm new here AND in Android culture. I was an iPhone user, but decided to swith to something different. Since I live in Europe (in Lithuania, to be exact) I figured that it wouldn't mean anything here if I bough a blacklisted T-mobile Note 3 4G LTE phone. Now to the main point - I got the phone yesterday and noticed something suspicious. Firstly, it came with aftermarket charger and usb cable (not usb 3.0, just a simple micro-usb to usb 2.0). My first problem is that when I am charging Note while it's on, it almost doesn't charge at all. Only when I turn off the phone I can expect the phone to charge to 80-90 percent in 8 HOURS! That's insane! Needless to say, I WILL be getting original samsung charger... Now other complaint is that the area around camera gets hot even when changing settings. Not really sure what causes that, so I did 4 factory resets yesterday.... Today it gets warm, but nothing suspicous. Disabled KNOX and other crappy programs. Not sure if it's the chargers fault, but battery life sucks. Phone drains the battery like crazy, the percentage drops about 1 in minute or so. When I use the power saving, reduce the brightness, use airplane mode, it's better, but even If i charge it and use my phone at the same time, the battery percentage still keeps going down
Now, the biggest wtf moment is when the phone is not plugged to charge, if i press the sleep button, the display turns black and after a few second the phone shuts itself off. No sounds, no vibration or notifications, it just silently goes to sleep. I can only turn it on again. I could even successfuly unlock the phone to use with a sim card, the phone is also making fun of me! Not really sure what's happening with my note that i bought off ebay and spent quite the amount of money, but I am starting to get into depression...
Please, if anyone has ANY idea what the hell is happening (apart the stupid charger), i would really appreciate any answers. And sorry for the long post and my english, as it is not my native language!

Could be a counterfeit - Check the serial with Samsung and make sure it has all the crazy samsung sensor, the counterfeits usually don't
Make sure the power button isn't sticking, I had an iphone 4s that did the same thing and it was due to power button hardware problem.
For the charger just get a cheap one off ebay with the right power ratings(find them for your country on samsung.com) and I find Toshiba sells replacement USB3 cables for their hard drives really cheap - That can save you 30$
Blacklisted IMEI phones are a gamble, if you can prove it's a counterfeit then ebay should refund you but it might also be a phone some bad man/woman/other stole and might have been abused. If it's the latter then that's a shame that he ended up stealing from two people...

Thank you for your answer
Well, the power button isn't sticking, I can clearly feel and heal it click when I am pressing it. The IMEI under the battery matches the IMEI in android system settings. I checked my IMEI on swappa and it says that phone was reported stolen (yay..). On imei.info site it says a different model (n9005 instead of n900t), but whatever.
Thank you for the info about toshiba usb 3.0 cables, might as well buy one right away
To be honest, I feel like it's a faulty item (even though seller assured my that the phone is working like new and that he replaced the battery). The battery life, as I said, is terrible, it doesn't hold a charge, the vibration motor seems very cheap (it's too strong, it sounds very strange), speaker seems to be not-ok too (distorted sound not even on full volume), screen-capture with palm doesn't even seem to work properly, I can't choose various music eq's (it says that this eq is not supported with speaker), I can't get my sim to work with this phone. Well, according to the ebay ad, phone should be working properly without any problems. The fact that the battery or charging mechanism sucks determined that was a lie...
Now I'm wondering if this info would be enough for paypal to refund me, because the phone is almost unsable (with self shutting of while it's not charging) and sad battery life...
Sorry for double post, but I noticed something very strange...
Well, turns out, that when the airplane mode is off, the phone gets very hot around the camera and battery is draining like mad. BUT, when I turn on the airplane mode, note cools off, battery still keeps draining, but it seems that not as much... Anyways, is it possible that the cellular module or something like that could be a cause of all my problems? (and to keep in mind that I haven't been able to use any sim with it, as it keeps saying "searching")
Sim won't work unless it's unlocked.
My suggestions are to:
1. Stock restore and then root the device.
2. Just sign in to phone using WiFi and download chain fires region lock away. Roughly $3 US.
3. Then try out Sim card, see if you can get signal.
If you can get that far, it will tell us what other kind of problems the phone is having on its own. Sounds to me at the moment it is trying very hard to find the signal and causing battery drain issues. The random shut downs could be due to the phone over heading and shutting down as a fail safe.

I did everything exactly as mentioned in the thread that you've posted the link to. First of all, booting logo changed, then my phone became unlocked (when I inserted the SIM, it didn't ask for unlock code). However, even with apn settings, it still says "searching" and gets quite hot in the upper-left side of the phone (when screen is facing towards me). I was really hoping this would help, but it didn't do much, as it seems... Anyways, I appreciate your good deed trying to help me I'm really desperate to make this phone work with my phone, but can't seem to manage to do that, which is very sad...
I realize this is a worse case scenario, but i used my phone as navigation for the first time today and after maybe 20 minutes of having it on my dash, charging, listeing to bluetooth music while navigating it quit charging and the red notification light started blinking. I had power saver on with the screen at its lowest Automatic Brightness set. I know this is a stress test for it, but lots of other phones I've had didnt have a problem like this. I dont use it as navigation too often, but it cant not charge if i do use it that way.
Anyone elses do this too?

Mine starts to get pretty hot with the basics....browsing..youtube...charging while not using. It's not happening all the time but it gets frustrating. This is my second m8 ( I returned my first for heat issues) so it's happened on both non-rooted m8s.
I went back to the tmobile i bought it from, they hooked it up to a laptop and ran a few tests on it and declared it fine. They said to call corporate tmobile tomorrow (since they took the holiday off today) and tell them whats going on and they can put it in my notes to have the store replace my phone tomorrow.
Anyone else's phone do this? I ask because corporate gave the store the OK to exchange my phone, and if this is a problem with all M8's, theres no point to exchange it.
I am debating on getting a different phone all together. I flashed a few Roms.... Still having the heat issue.
Sent from my HTC One_M8 using XDA Premium 4 mobile app
So I was able to trade my phone for a new one at the store,...I'm now past the 14 day trial, so I hope this one is OK.
Are you guys sure it gets that hot? This is the same thing with the M7 and people were saying the same thing. It's thermal conductivity which you guys are feeling. Keep in mind just because your other phones don't feel as hot doesn't mean it's not the same temperature. Here's a video about what happens and how people confuse themselves. The M7 and M8 are different and the M8 should conduct more heat due to it being more metal.

Although yes, it's hot to the touch, I'm talking about the battery getting so hot it quits charging , the Orange led blinks, and the battery starts going backwards even though it's plugged in to the car charger.
That's why I was making sure if it isn't merely it feels hot, and not actually being hot.
Are you using a 1.5 amp or something higher? I notice when I use large amp charger it'll get hotter than usual, but it does charge quicker.
It's a Verizon generic car charger, 1 amp. I'll be using the replacement phone tomorrow afternoon for navigation, I'll report back if it's any better with it.
I Just found a 2.4 amp Rocmetfish charger that gets good write ups at best buy. Wonder if that would help.....2.4a is a lot more than 1a.
I dropped by tablet battery down once and now every so often the screen flickers with vertical lines and this is followed by loss of network and the thing reboots.
I've read this to be a battery problem.
Warranty is still active but I've rooted it and my Knox counter has gone up.
What do you think XDA? Just get a replacement battery?

If you have the ability, since it was dropped, I would open it and make sure connection is tight to battery and screen. Then if it still acts up, get a battery. Several people had battery issues out of the box. All it turned out to be for a few was a loose connection.
i was thinking about that but i'm afraid of voiding warranty. do i even still have warranty? due to the knox?

Well ive opened it up and tightened everything i can see and it seems to work ok for a while, when the charge gets to around 20-30%, the tablet flickers, all mobile connections are lost and 75% of the time, reboots.
So i went ahead and got a new battery. Now this was worse kinda. At random moments, like unlocking the screen, or replying to a message, or maybe just a high cpu load event, the tablet just turns off and is unable to be powered back on without first connecting it to a power supply like a wall charger or a power bank.
The time and date will be reset once its back on and ill have to wait a few minutes before the auto network time setting kicks in before i can use something like whatsapp.
Anyone got any clue what might be causing this problem? Thanks in advance, helpful xdarians.

I'm not by any means an expert or repairman of any kind, just so you know. I'm thinking maybe a loose connection at the terminals on the board the battery connects to or if they use a separate board for the battery to connect to and then to the main board it may be somewhere along in there. Maybe a loose wire going into the tab that connects to the prongs. It sure sounds like something isn't making a good connection. Sounds like a load gets put on it and it and that bad connection can't handle the load.
Might just be you're going to have to send it off...
You may be right. Sounds like a particular connection which does higher load or something. Once i put the tablet in power save mode, the symptoms never reappeared. I dont notice a drastic slowdown in the tablet either. Probably am prolonging the inevitable.

I am facing exactly same issue what you have described and am in same situation, have tripped Knox on my Tab S 8.4.
I can see that you have been able to suppress the behavior by putting it to Power Saving mode. Have you experienced flicker and reboot since then? I am planning to take it to Samsung store not sure if they will honor warranty, did you tried that?

nope, ever since the Power Saving mode solution, it hasnt flickered and rebooted yet. and my warranty was expired by that point so i didnt bring it to the shop. no noticable reduction in performance so far

I have seen this problems on 2 tablets 10.5 and 8.4 the connector where battery is connected on motherboard gets loose which causes reboots and flicker
Solution in my case was resoldering that connector again
i had the same problem, opened up my tablet, just disconnected the battery, cleaned the contacts, pushed it back, made sure its nice and snug, put it all back together and now battery doesn't drain as fast, no more flickers and reboots!
hmm. i'll have to give it a try. you think this may be something to do with condensation?
Sorry for the bump, but I'm having this issue as well on my S 8.4. Custom ROM. The thing with me is that it's not consistent. One day, it will do it a few times; others, no issues whatsoever. I'll try the suggested if it gets progressively worse.
Hey guys,
Unfortunately our home's tablet (Tab s 8.4 Wifi) has the same problem.
It never did weird whatshowever, but when I flashed a custom rom (which went perfectly smooth actually) the screen flashes and the tablet reboots sometimes.
Now it weird that this never happened before and only when I flashed a custom rom it began showing this behaviour.
I am affraid of opening this tablet, and I guess because of the custom rom there is no warranty left anymore (or can this be bypassed by some terminal trick?)
Also I question myself if this is not a software issue, and that it can be fixed with software or so?
Thanks for answering!
My Fix
Hey Guys!
I might have some surprising news to tell about this "issue".
I saw some unboxing video's and saw at what place the battery connector was placed. It was some sort of a 'push to click' system.
So what I did was the following:
I pushed the tablet at the place of the battery connector. I tried this at various places until I heard a *click*.
Now I don't have this issue anymore. Jay!
I hope this will help you too!
I started to have the same issue on a Tab Pro 12.2, presumably after the battery has lost considerable amount of its energy. Normally I remember this tablet to have a dazzling 10+ hours of usage time. Just after some serious usage time of more than 2 years this issue started, along with increasing temperature and finally reboot. From time to time Android gave a warning message about overheating. From time to time charge values drop big values at a time. From 45 to 20 or 80 to 50. Seems arbitrary. This was happening even when I was on stock, then I switched to some Android 6 stock port from some other tablet. Still the same.
I believe the battery needs replacement. (That's obvious after 18 months, I just mean blinking is related to this) Hope I can find a high quality one cause there are several garbage batteries.
First of all, I'm not a noob regarding electronics and batteries.... Second, I don't think Samsung did such a stupid mistake like using millions of batteries without testing them and third, I don't think that a company who is producing batteries for a mammoth like Samsung can afford to sell defective batteries, or not properly tested batteries...
I'm the owner of a blue Note 7, and I am ready to take the chance and NOT exchanging the phone.
And this is why:
(please excuse my English...)
At the beginning, I have noticed that every single time when I was charging my phone, the phone was kinda overheating... Not too much, but still....
After that, the big scandal about exploding batteries was everywhere in the media...
I have read in the phone settings that SPEED CHARGING can overheat your phone (actually is overheating just the battery)....
So I've just disabled the speed charging on the phone and the now the phone is always cool
So my personal opinion:
I think that the problem is somewhere in the speed charging process, something that is shocking and putting too much pressure on the batteries, probably not proper designed for fast charging.
So I'm taking the risk and not exchanging my phone, and I suggest to all of you guys who are not exchanging your devices to do the same, especially because the charging speed is not too much different regarding the speed!!!
Please test and post your experience regarding charging speed and phone temperature with the fast charging option enabled/disabled....
Thanks, and again, this is my personal opinion, and I'm not advising anyone NOT to exchange the phone.
Just a couple of points on your post.
1. It's not all phones that have the reported problem - Samsung have a few different battery suppliers and only one has delivered faulty ones. The problem is that Sam has no record of which phones they went into.
2. Phones sold in China have not been recalled because Sam knows the dud batteries weren't used for that batch.
So a general charging problem doesn't explain the situation. But yes of course fast charging will make the battery hot.
My personal opinion what is the big deal no sweat off your back. Change the phine and get it over with.
The liability you are assuming is not worth a few hours of set up
on the testing front, it is impossible and far too time consuming and detrimental to the product to conduct full scale testing on every single thing coming out of a factory, the fact is mass production should make it so item 1 and item 1 million are identical, so due to the process they will do spot checks randomly testing say 1 in 100, now when you hit a problem like this battery fault where the actual fault is a very very small percentage it's like trying to find a needle in a haystack, you can poke at it randomly as is the industry norm (even with cars) but the majority of the time you are going to come out with hay. the only way this could have been caught if every single battery was put through intensive inspection and usage tests before they shipped, not only would this add a massive amount to the production cost and time it would also lead to the battery already having some pretty harsh wear and tear on it.
so the testing is pretty much manufacturing standard and the same as every other company worldwide, so if Samsung for doing this then you are saying every single company the world over is stupid.
on not exchanging the phone if the option is there it would be stupid not to, as basically if it does fail down the road and you refused the recall then you have no come back as you were told and given the chance to have a device deemed to be safe.
the fast charging claim was made up by phone shops, it's not one Samsung ever put forward. yes fast charging can generate increased heat, but the battery isn't failing because it is hot, it is hot because it fails. the actual failure of the battery is a short circuit caused by a fault making the 2 sides of the battery to bridge leading to the battery to have a runaway reaction, you can actually do this on any battery should you use something to short both sides of the battery together. now here lies the problem, people erroneously claim don't fast charge as it reduces heat, but when the flaw comes from parts of the battery that should never touch coming into contact with each other, slow charge or fast charge if them 2 parts are close enough they can touch they will eventually. so yeah heat is a symptom not a cause, with temperature things can expand and contract but the fact is if the short can be made on a device anything you do is only delaying the inevitable and there is nothing you can do to stop it eventually failing.
but end of the day if you want to risk it and live with 60% battery power that is up to you.
I agree that the vast majority of batteries are probably fine.
The hassle of keeping will be having to deal with airports, gimped 80% battery and possibly IMEI blacklist.
The hassle of exchanging is getting a unit with screen or hardware other problems. As well as (like in my cause) having to exchange out of region, the process of which still isnt clear to me. I am currently playing ping pong with samsung UK and samsung Gulf (i am the ball)

on the testing front, it is impossible and far too time consuming and detrimental to the product to conduct full scale testing on every single thing coming out of a factory, the fact is mass production should make it so item 1 and item 1 million are identical, so due to the process they will do spot checks randomly testing say 1 in 100, now when you hit a problem like this battery fault where the actual fault is a very very small percentage it's like trying to find a needle in a haystack, you can poke at it randomly as is the industry norm (even with cars) but the majority of the time you are going to come out with hay. the only way this could have been caught if every single battery was put through intensive inspection and usage tests before they shipped, not only would this add a massive amount to the production cost and time it would also lead to the battery already having some pretty harsh wear and tear on it.
so the testing is pretty much manufacturing standard and the same as every other company worldwide, so if Samsung for doing this then you are saying every single company the world over is stupid.
on not exchanging the phone if the option is there it would be stupid not to, as basically if it does fail down the road and you refused the recall then you have no come back as you were told and given the chance to have a device deemed to be safe.
the fast charging claim was made up by phone shops, it's not one Samsung ever put forward. yes fast charging can generate increased heat, but the battery isn't failing because it is hot, it is hot because it fails. the actual failure of the battery is a short circuit caused by a fault making the 2 sides of the battery to bridge leading to the battery to have a runaway reaction, you can actually do this on any battery should you use something to short both sides of the battery together. now here lies the problem, people erroneously claim don't fast charge as it reduces heat, but when the flaw comes from parts of the battery that should never touch coming into contact with each other, slow charge or fast charge if them 2 parts are close enough they can touch they will eventually. so yeah heat is a symptom not a cause, with temperature things can expand and contract but the fact is if the short can be made on a device anything you do is only delaying the inevitable and there is nothing you can do to stop it eventually failing.
but end of the day if you want to risk it and live with 60% battery power that is up to you.

BTW, I didn't update the phone with the last update, I've just turn off automatic updates in settings... I'm curious if I can skip this and will be able to update next time when Samsung will release a update....
You won't be able to give it away when you come to sell if you don't exchange it.

My note 7 to heated up too during that one time during its first w days. It was really really hot...I turned off fast charging and it never happened again.
I also believe it's related to fast charging...which is on by default.
Using generic adapters and cables hasn't made it hot every since i turned off fast charging.
But I'm still having this replaced..sad because I have no problems with this unit..GPS works perfectly and fast. Battery last long. And now the news is reporting that the new note 7 replacements are showing problems is South Korea. Over heating and not charging....sigh

the updates have to be done in order you can't skip one and go onto the next, if you get the next it will include this one so basically using that method you can never update the phone.

First of all, I'm not a noob regarding electronics and batteries.... Second, I don't think Samsung did such a stupid mistake like using millions of batteries without testing them and third, I don't think that a company who is producing batteries for a mammoth like Samsung can afford to sell defective batteries, or not properly tested batteries...
I'm the owner of a blue Note 7, and I am ready to take the chance and NOT exchanging the phone.
And this is why:
(please excuse my English...)
At the beginning, I have noticed that every single time when I was charging my phone, the phone was kinda overheating... Not too much, but still....
After that, the big scandal about exploding batteries was everywhere in the media...
I have read in the phone settings that SPEED CHARGING can overheat your phone (actually is overheating just the battery)....
So I've just disabled the speed charging on the phone and the now the phone is always cool
So my personal opinion:
I think that the problem is somewhere in the speed charging process, something that is shocking and putting too much pressure on the batteries, probably not proper designed for fast charging.
So I'm taking the risk and not exchanging my phone, and I suggest to all of you guys who are not exchanging your devices to do the same, especially because the charging speed is not too much different regarding the speed!!!
Please test and post your experience regarding charging speed and phone temperature with the fast charging option enabled/disabled....
Thanks, and again, this is my personal opinion, and I'm not advising anyone NOT to exchange the phone.

I agree with you 100%, through my own testing i came to the same conclusion which included charging from power point/usb and wireless, i believe heavy use, fast charge and a defective battery caused issues, not just battery issue , in my humble opinion i believe incorrect using of fast charging was probably an issue in all legit cases, but Samsung should of put some type of time limit for fast charging, ie 90 minutes, that way would of negated one part of the equation and probably stopped a few bangs, so blame all around really
If it was fast charging that was the problem don't you think samsung would have disabled it with the replacement phones?
Kudos for starting the thread by stating what's said is "your opinion." We're all operating off of second and third hand data yet some here will defend their interpretations as fact. Clearly they're not and can't be.
This explains the battery issue. If fast charging made batteries overheat than you'd see events like this on every forum for every OEM. S7's don't have this issue and they are only three months behind the Note7 in development and share many of the same internals.

I'm glad that i left Samsung family cuz It was pretty damn sure that someday my phone will kill me
Samsung is going the apple way i guess.... Just to sell it... Now apple doesnt look that expensive.... :/

Yes, you are a noob, you don't know anything about batteries.
Current Li-ion batteries can be safely charged with approximately 40 watts of power. Fast charging in Samsung phones utilizes only 15 or so watts.
It's not the fast charging. It's a just a tiny percentage of batteries with a defect.
I fast charge mine all the time and it stays pretty cool. I'll still switch when my replacement arrived, but in the meantime I am not worried.
Hi,
I have a question about whether wireless phone charging affects spen. From about March to November, it happened to me twice that the phone said spen disconnected. After inserting it a few times, it connected again and worked. It's been happening every day for the past month, and for the past week it's been constant and won't connect. I read something about magnets in the discussions, but the phone did not come into contact with anything like that. The only thing I can think of is that for about the last year, the phone has only been charged wirelessly, by leaving it on the charger overnight. The charger is not original Samsung. Is it possible that the spen broke due to the charger? I got a new one today, it works perfectly again and I would hate to destroy it again. What is your opinion?
Please excuse my English, I'm using a translator
Interesting. Spen's seldom fail unless physically damaged. Sometimes they can be hard to get to initialize especially if not used for weeks. Eventually they will initialize though, the first indication is they show as charging. The old spen may still be good... just being stubborn.
Best to use Samsung chargers. The wireless charger shouldn't effect the spen if not actively charging. The Spen has it's own charging coil built into the phone. However not sure if the spen is shielded from outside RF. Unless the external wireless charger gives the spen a substantial over voltage if it can even charge it, it wouldn't harm it. The spen uses a super capacitor for it's battery and can't be overcharged. Over voltage may kill it. This is a question for Samsung engineers... good luck with that.
Spen's and magnets don't get along but a permanent magnet exposure shouldn't cause any permanent damage.

thanks for the reply
it's just my guess, because otherwise the spen was always fine and I don't know what else the phone would come into contact with.
Girlfriend still has my old Note9 and spen is still no problem and she basically doesn't even use it.
He is not physically damaged in any way. Over time, it just started to get worse.
The last two weeks or so, he was almost unable to connect. Rather, he was still disconnected. When I managed to connect it after a long trial, in the settings it showed charging from approx. 60% to 100% and for a very long time. Sometimes it even managed to charge, if it hadn't lost the connection by then.
When it was working, the battery dropped from 100 to 80 immediately after pulling it out, and then it wouldn't connect again after inserting it.
At least I'm glad it was spen and not something inside the phone

You're welcome.
Could be the spen failed electronically which is very rare unless damaged. Guess if the new one fails you'll have the probable cause.
Wired charging puts less strain on the battery and is faster... so you may want to consider using that instead. The C port is generally very robust and is good for many thousands of use cycles. In the N10+ it's fairly easy to replace and is an inexpensive part. So don't sweat it... enjoy your N10+, it's Samsung's best phone to date!
Just a joy to use and very capable.
