Wireless charging has stopped working

The problem I have is sometimes the blue light will start blinking & stops charging. Happens with an oem Samsung wireless charger and the free charger. Any suggestions?
 
G'day,
I've just got myself an S8+ and I love it, but I think I stuffed up the settings somewhere.
I've been reading some of the posts here and in some ways there could be a link.

I haven't read all the posts as my attention span is pretty bad these days thanks to a cocktail of pain meds and antidepressants thanks to a workplace injury.

When I got my phone I was wrapped. It was very fast and everything worked very well. I tried the performance mode and was very happy, but I felt the normal mode is fast enough, especially considering I had upgraded from an S5, which had issues with the lack of memory.

For the past week I have been installing my favourite apps, and have been messing around with the settings. Up until yesterday, the battery was going great, but I had found a battery setting that I could put some apps to sleep all the time, and I added all apps that I wouldn't use that often, such as games, and utilities, such as network testers, speed tester etc.
Then I had installed a PGP app so I could send encrypted emails, but I had trouble setting it up to work with my email app (BlueMail). I then found that BlueMail started to freeze and lag, so I uninstalled the PGP app and restarted the phone which helped, but not fully.

Last night I popped my phone on the wireless charger and it appeared to be working, but this morning I found the battery was only at 48%.
I had bought the charger for my S5 as I got sick of opening the little door to plug it in all the time. My wife had the S5 as well, and she broke her little door.
The first charger didn't work as the coil in the receiver and charger didn't line up, so I got a Floureon triple coil charger and it mostly worked. I had to put a pen on the base to lift the phone up and it charged.
With the S8+ I found it was perfect, even better than I realised. The phone charged when I put it on, and the blue light went green straight away. I discovered that when the phone is fully charged, the light changes colour to show it was full. I didn't know it did that.
I recommend the Floureon triple coil charger, it's affordable and it works well. It even charges reasonable fast, especially with the S8.

Considering that I was messing around with some settings, and a couple apps, I think it most likely that I did something wrong somewhere, although right now I can't figure it out. I have tried changing the settings I remember fiddling with back to the way they were before. I removed all the apps from the permanent sleep setting, but no luck.
The charger still works, as the light goes green, and the battery icon on the phone shows it is charging, but it never fully charged. I've got my S5 on the charger now, and it's charging nicely, although no way as fast as the S8+ does. Ok, the S5 has a charging receiver stuck under the back cover, so it's not a proper charging cover, but it does charge, just slowly.

I came here in search of some answers in the hope someone might read this and the light bulb lights up in the head, and thinks of the magic answer which can help most of us.

In the S5, I know the settings and where everything is, but the S8 is totally different, it has some new settings, and some of the old settings are no longer there, and some are well hidden.

I know one solution is to reset the phone and start fresh, but that's not my preferred solution as it can easily happen again if I don't know which settings are responsible. And of course I've been slowly adding my old apps that I had and used before. I've had the phone for about a week and in that time I have backed up my S5 and took my time setting apps up, and trying to figure out the settings. And I'm also somewhat stubborn lol. I used to be a mechanic and I disliked the plug n play systems cars have these days. I would have been suited to the days when mechanics actually fixed a car, rather than remove and replace parts the computer says to replace.
I have been known to stay up all night fixing something rather than give in and reset.

I think that some others here are having a setting issue rather than the phone or charging pad being dodgy.
It's easy to blame the hardware than a setting or app . Sorry, no disrespect intended.
Has anyone tried to not add any apps, or fiddle with any settings when getting a replacement phone to verify if it's the phone? I would be curious to see if the problems exist prior to setting up the phone or if it really is the phone, especially considering that the issues happen after a period of time, rather than straight away.

Prior to my injury I was very good at fixing things. One of my previous jobs was a systems tester with Telstra which is one of our big telcos here in Australia. And I was good at it, but the job became redundant and I took a package.
Now, since the injury, I lack the attention span for such things.

Sorry for the long winded post, I tend to ramble on a lot these days lol.
 
Did you get the newest version of the wireless charging pad? Samsung changed the rules somewhat with the S8 series regarding wireless and I would assume that carried forward to the Note 8.
Both the S8/S8+ and Note 8 use Qi. ANY Qi charger will work. I have two older and the new wireless Samsung wireless chargers and they all work fine.
 
My Galaxy S7 with Otterbox Case, and Samsung Fast Wireless Charger Model EP-NG930 are about 2 years old. They charged fine until this Fall (after September of 2017). Now my phone is waking me up at night as after it charges the screen comes on and lights up the room. Then Wireless charging is paused, then Wireless charging is started and the phone lights up and beeps, (Just to make certain that we wake up). Then it repeats two times per minute.

So I've found a setting to turn off the annoying beep. But no setting to have it not wake up. So I'm charging it during the day, but...

Now when I put the phone on the wireless charger it says Fast Wireless Charging, followed by battery %, followed by Fast Wireless Charging Paused. Or if it does work it does the off/on/off/on two times perminute once getting a full charge. Or it pauses and does not charge. The only way I've been able to make the fast charger work is to unplug it, take the phone off, plug the wireless charger back in, and place the phone back on the charger stand.

Removing the otter box case has no affect.

The only correlation I have is that this all started after one of the monthly software updates. Or old age and the charger is failing. I posted a thread on what I've done to try and fix this. Fast charging using the USB cable always works fine and does not wake us up. But I don't like wearing out the usb connection which is why I bought the Samsung S7 and the Wireless Fast Charger in the first place.

The phone must communicate to the wireless charger. Maybe new chargers use a different protocol and my original charger has been made obsolete due to a Software Update. Otherwise rebooting the wireless charger should not make a difference.

My next issue is that if I do not remove the phone when the charger turns green, and the phone wakes up, then the phone uses some battery, and the charger is "found", and the phone lights up using more battery, and the charger is paused, and this repeats so that when I go to get the phone I'm at 75% or less.

I can not stand software updates. I might be wrong and it could be a hardware issue but I won't believe that and if the software had not been updated prior to the failure or for at least weeks after an update then maybe I would suspect the fast charger instead. Even if I buy a new one there is no proof that the software didn't cause the old one to become obsolete.
 
It's possible the charger is going bad. I doubt it was a software update. We have three Samsung wireless chargers and all of them work fine. Two of them are the older models that were introduced with the S6. The other one is the new convertible one.

I've even used an old Nokia wireless charging plate and it worked.
 
Well I haven't had my wireless charger checked yet. But I did have a nice long eChat with Samsung. I'm convinced that the SW updates are the source of the problems. Samsung's technician stated "Samsung Does Not Recommend You Wirelessly Charge Your Phone Overnight". Then they told me that the screen is supposed to light up when charged so that the user may remove it from the charger. "We recommend that you remove the phone from the wireless charger after its charged." "We do not recommend you leave the phone on the wireless charger for long periods of time." Also "We recommend that you unplug the wireless charger when it is not in use."

So their SW update that wakes me up is to get me to remove the phone from the wireless charger. Even at 1 or 2 AM.

And then the fact that I have to unplug the charger before it will charge again, reminds me to unplug the charger when it is not in use. Or it will not work. So you might as well unplug it right away right? At 1AM. When its done charging. Where you have to reach behind the bed to unplug the wall wart.

NOT.

I conclude that after two years of charging my phone on the wireless charger overnight, Samsung has concluded that its not safe to do so. Without actually stating that its not safe nor admitting that their is a problem. But it must be big enough, or enough of a chance, that they changed their software. That alone should be an admission that their is a measurable problem.

This could be because there are numerous wireless chargers out there. And the original Samsung charges might have been okay but they can't guarantee that I'm using an original.

The wireless chargers must be Unsafe. Or they wouldn't wake us up to remove the phone and unplug them.
