Qi Charging Issue; Turns On and Off at 100% Charge - Galaxy Note 4 Accessories

Do any of you have an issue where the phone screen turns on and off (and beeps) when it reaches 100% charged using a Qi charger? I am using the official Samsung wireless back cover with a Nokia Qi charging pad. When the phone reaches Charged, it will turn the screen on, then it'll say Charging Wirelessly 100%, then it'll turn the screen off and start charging... and the cycle repeats every 20 second or so. Anyone else?

I think it is standard glitch on all Samsung phones. The same thing happened with my old Note II, and it happening with my Note IV too. I have to shift phone maybe 1" off center so it would not make that noise.

Yes, I turn off notification and system sounds at night while charging with Tasker, and I use Gentle Alarm to display a dim clock so I don't get the screen flashing.

Thanks for the quick reply! Now I know that it isn't just my phone or charger, I can rest easier and just let it be (mostly will just take it off stand when charged).

My Note 4 is using S-View cover with wireless receiver built in + OEM Samsung Wireless Charger Pad (the big one) & I never experience your problem.
It only shows "Charged" once then fall asleep again until I turn it on.

this is correct if the note 4 is not properly centered ona single coil charger. upgrade to a 3 coil or center the charger coils with the base.
it takes place because the signal to cut off the charger at 100% is not properly received by the charger base so the charger keeps charging. the note 4 assumes the sginal sent will cut off charging and goes into a no charge state. then when current keeps flowing through the coils it wakes up and issues a no charge command again...which is again lost because the coils are too far apart. and the cycle repeats.
solution is to switch to a 3 coil charger or align the coils with each other.

Is there a way to find out how many coils in my charging pad?

[Q] Nokia Wireless charger continues charging after battery is full

I bought a Nokia wireless charger from ATT online store.
It works on my nexus 5, but when the phone is full charged the LED light on the charger is still solid on (on means charging, and blinking means done). However I go to Setting->battery, and it shows battery is full.
My question is which one is right?
-Wireless charger is still charging the phone.
-The system shows battery is full, so the phone won't be charged. But since the charger is Nokia, so it doesn't know my Nexus 5 battery is full.
Thanks in advance
I believe there phone will stop charging the battery buy the charger won't know so it'll keep going. The phone has the circuitry to prevent damage to the phone.

I purchased (2) tylt wireless chargers from kickstarter a while back and I planned to keep the N5 cradled most of the time.
Unfortunately while the chargers work great they also heat the battery to 110 F while charging as compared to around 80 F with a straight USB charger. I'm afraid this heat will eventually kill the battery. Since the battery isn't easily replaceable I've decided to abandon the wireless chargers.
The batteries and the whole device stays hot after its charged and until I pull it off the charger. I didn't notice whether the charge light actually went out on the charger itself after the charge was completed. If I'm brave or (dumb) enough to try it again I'll report back.
Anyone having better luck with the stock wireless charger or other wireless chargers like the Nokia?
I purchased the same Nokia wireless charging pad, and, despite the LED not turning off on the pad, the battery DOES stop charging once it is full.
This can be observed through a battery monitoring app like Battery Widget Reborn. If you look at the battery graph at any point after the battery hits 100%, and before you remove it from the charging pad, you'll notice an even 2 or 3 percent drop and rise at regular intervals. This is the trickle charge mechanism. Once the battery is full, it stops charging, Once the battery drops down to a certain percentage, the charge resumes, and the cycle repeats itself until you take the phone off of the charging pad.
Same here with another brand on wireless charging pad, I think it's normal

Are you not concern with premature battery wear considering now it's not user replaceable? Heat is supposedly not good for battery life.

This really explained me what happens. Thanks !!!

How do you manage the notifications/screen on when wireless charging at night?

As per title, I have a wireless charger now and like most people I imagine, charge the phablet at night.
So the first notification/screen on I can tolerate to tell me it's charging but then there's the charging complete notification/screen on and then to and fro as some juice depletes and it goes back onto charge.
I'm not rooted (bought the phone outright recently and don't want to invalidate warranty).
I am averagely familiar with using Tasker and Trigger and am open to any suggestions to stop me getting woken up by this.
It seems such an obvious Use Case I am amazed Samsung haven't provided an easy way to do wireless charging without these interruptions.
Thanks,
Joe
I haven't noticed any interruption in charging wirelessly. I get the notification that it started, the one for full, and that's it. If I leave it on the pad it just acts like it is plugged in and maintains until I remove it.
Fwiw, I'm using the PThink Ultra thin qi receiver w/nfc and a yipin q300 dual qi charger. Does the same in my powerbot puck, too.

Lightflow will allow you to override the factory settings for both of these. You can set quiet hours as well.

I'm starting to wonder if I have a duff charger mat. When it's at full charge the charging notification comes on every two or three seconds. The mat is quite hot to touch and my battery monitor app shows 39 C.
It's a Choe mat so only a cheapie.

wireless charging going bad?

I've had a Nexus 5 since mid November 2013. Each night it is charged on a Tylt charger, during the day at my office I have the newer Nexus charger. Within the past month, the Tylt has been intermittently not charging (the green light on the bottom won't light). I could sometimes have success if the phone was turned sideways. But the nexus charger would usually do the trick. Recently the Nexus charger won't get the phone in wireless charging mode either, whether the phone is on or off.
Anyone had wireless charging go bad? Anything to try other than call Google and swap it out? Sean

If you have access to another Qi Wireless Charger try it on that, otherwise it could just be a problem with the coil even though that's unlikely. Did you pull off the back cover at any time?

It's not 100% clear but I believe when he says the Nexus charger he means the Google Qi charging unit, so he would've tested it on there and the Tylt.
Question: Have you ever removed the backplate? Or maybe dropped the phone? If so one of the clips securing the backplate might have loosened.
Try pushing down on the back of the phone right around where the X or S is andif you hear a click it should've snapped back into place. This is most common for people who have removed their backplate.
The clip that's typically the problem can by located thus:
Form a cross (two perpendicular lines), with one line running along the bottom of the letters in NEXUS on the back cover, and the other line coming from the flash. The clip is located where those two perpendicular lines meet. Press down there to ensure it's properly seated.
The entire purpose of that clip is to ensure that the wireless charging contacts seat correctly. If that clip is unseated or broken, you'll (eventually, if not immediately) have wireless charging issues.
However, it doesn't take much to damage the wireless charging system in the N5. My first unit stopped wirelessly charging after I dropped it from a height of about 2 feet (from a seated position), and it landed flat on its back on a tile floor. Luckily, if you bought it from Google, it's still under warranty, and wireless charging not working is a valid warranty issue. (Hence, why I said "my first unit.")

Wireless charging is too sensitive.

I'm not new to the insert and qi charging station, I've had it on my s4 for almost a year.
I've been using the same Nokia dt900 charger for the s4 and now my note4.
I know there is a little issue getting the phone to charge, seems it's picky on position but I was normally able to find it on 1-3 tries(under 1 minute). But with the note it's been more like 10-15 tries (2-3minutes). And sometimes it would stop charging overnight.
Anyone have this issue? I'm trying to figure out maybe I have a bad insert or maybe the Nokia charger has too small of a coil, I would to try a charger with a larger coil (not larger overall surface). you can see the coil imprint of the insert, I can asume the circle in the center of the charger is about the same size. I've been lining them up this way but it's so annoying. I'm just ready to call it quits.

I have the TYLT charger and i had the same issue. I ended up finding out the phone liked to be slightly to the right of the charger for a good charge lock. I had heating up issues with my first insert (Nillkin) and ended up buying this
Haven't had any issues since.
That's the insert I have the qi-infinity.
get a 3 coil charger. the old 1 coil designs have this problem. with a 3 coil you just throw it on the charger.
Don't have any problems with first try
I made this base for my charging pad out of left over 1/4" thick acrylic. It has adjustable height, so it is easy to find best spot.
I think it makes a big difference which insert you use. My first one was VERY picky, but I got a different style (square with single inverted "L" contact at the top) and that is much better. The coil on that one is slightly off centre, and so the phone needs to be offset to the right a little for best results.
I'm going to try the official QI case mod - the Samsung coil looks bigger, and definitely central.
I do have issues with that as well. This is why I recommend just plugging the darned thing it. Takes less than 3 seconds, and it works EVERY TIME Without fail.
I am using the OEM S Charging View Kit for Samsung Galaxy Note 4 (Charing Pad + S-View Cover) & I have no issue at all.
It charge at any position even at uneven position.
[Review+Tips]Samsung S-View Wireless Charging Kit for Samsung
The insert type receiver I tried was very picky on placement. I switched to the OEM charging back and it is much more forgiving. With the Samsung mini charger pad I can just center the phone and it works every time. With the Tylt charger I found that placing the phone horizontally works every time while I could not get a reliable connection with the phone vertical.
I agree. I had no particular problems with my S4. However, with the Note 4 it tried my patience and was no longer convenient. It was easier and quicker to just plug it in. Also, I didn't like the heat generation. I've since stopped using the Qi charger and returned the receiver. I've gone back to my tried and true technique of having a spare battery available. Much quicker and I don't have to worry about how much battery life I have left for the day.

[Q] Wireless charging issues?

Hi
I brought a Samsung wireless charger. The first few days, it worked flawlessly, but today when putting the phone on at 27%, when it hit around 85-90%, it started saying "Wireless charging have stopped" even tho it still charges. It's annoying, cause the screen light up, it vibrates and I get notification about it, but it starts charging right after?
Do you think this is a phone or wireless charger problem? Also, will this hurt my battery in any way? I mean if I leave it overnight, would it hurt the battery that the battery start charging, stopping again and then start again? This is around every sec or so.
Thanks in advance
Sometimes, that charger is finicky. You need to position the phone just right, and if it slides a little bit, it can start connecting/disconnecting. When it does that, try just picking it up and setting it back on the charger. I try to put just above center on the phone over center of the charger.
samsung S Charger Wide works
I bought the Samsung S Charger Wide qi charger, it predates the S6 round charger. It's also cheaper, although it does not come with a plugpack or USB cable. It needs a 2A charger (such as the one which comes with the S6). It charges easily even with the Samsung S View case in use. This older charge is about the size of Note. It has a slight lip making it harder for a phone to slip off.
does wireless chargers is fast as the fast charger provided?
No. It is a lot slower although the difference is much greater if your battery is very depleted. The performance gap is lower as the battery charges because the fast charger 'slows' down.
It's charging at 927mA according to GSam Battery at about 80%. That's not too bad.
