Experiences with Qi wireless charging receivers?

Does anyone else have any experience with Qi wireless charging receivers for the S4? I bought one from eBay at the end of last year (item no
151128038769), and it was fine for the first few months, but now it doesn't seem to charge the phone at all. I get a popup message when the phone is placed on the correct part of the charging mat (although this message doesn't always pop up as reliably as it used to), and the charge indicator displays in the notification bar, but if I return to the phone half an hour later it has actually lost charge.
I've tried this with two different charging pads, from two different manufacturers, and neither charges the phone, even though the phone gives the impression that it is being charged when I first place it on the mat. Charging using a cable still works fine.
I was wondering whether others had experiences of wireless charging?

Update: I just checked the charge status with the Galaxy Charging Current Lite app. When the phone is on the pad the charging current shows as 640mA (which should be enough to charge?), but the phone is actually losing 1% of its charge every few minutes.
???

are you using an adapter cover or a connector for the qi charging?, maybe they're not aligned well
also,i just checked and i get 460mA via simple usb/PC charging. and it's still charging. (really slow, but charging.)

I'm using a receiver insert. It sits on top of the battery, and has a flap which covers the charging terminals higher up the phone. I'm more than happy with 640mA as I usually charge it overnight. I just don't understand why it's losing charge instead of charging.

if it's charging with 640mA, but still your phone is discharging, then maybe your phone is draining the battery.
try to close everything, such as wifi, GPS, mobile data etc. and then check if it's still not charging.
also, you can try changing to a a different receiver, if you have one
btw, what about normal charging? does it charge normally?

Yes it seems that there's something that's draining the battery faster than the Qi pad can charge it. I've tried a reboot but it made no difference.
"Normal" charging using a USB cable is fine (and quick). I've just set up the Better Battery Stats app to see what's causing the drain while it's on the charging pad.
I don't have another charging receiver to try (only another charging pad, which exhibits the same behaviour)

Finicky charging?

So we've been combatting some finicky charging issues with my wife's new S5 for the past week.
I've worked out a lot of the weirdness due to the fact that my HTC M8's charging brick apparently doesn't work with anything other than the M8 (I have no idea yet what is different about it... 1.5A).
Anyway, despite this we have had no issues using the supplied charger/cable (only used it on first day).
We haven't had any issues using an old Droid 2 charger and cable (1.0 A I think)...although likely it was a slow charge.
But, since we've been out of town for a few days without all our cables, the only think that has worked with NO issue is using a 2.1A output power brick to recharge the phone. Also, it seems that the 2.1A iPad charger worked as well.
What is weird is we also tried 2 identical 1A iPhone charges. Upon first plugin with a 10' 24/28AWG cable, it didn't charge. I removed it and plugged it into the other one and it began charging. I then removed it and plugged it back in the first and it started to charge fine (and yes, I tripled check the connection on the first try).
In short, we seem to just have very strange results. Sometimes it will say it is charging for a few seconds and then stop and sometimes it will not charge using a certain combination, but when you unplug it, try something else, then back to the first it will work!
We've also had issues with the charger in the car where it would keep blinking her phone on and off with a sound. I suspect that this was due to a slow charge bringing the phone to full charge, then dropping (even though plugged in), then going back to full again. But this is just based on what my wife described.
Can anyone explain and/or tell me what the minimum required and the recommended specifications are for a charger/cable on this phone?

Dead YD206

So YD206 about a month old. Was connected to official yota charger (via a magnetic usb cable), noticed the plug at the phone end getting quite hot. Phone now essentially dead, wont boot, doesn't seem to charge. We also realised the charger had come out of the wall socket. But the yotaphone light was intermittently flashing on the charger.
Whilst I am inclined to blame the magnetic charging cable, is it possible for current to flow in reverse from phone to charger and essentially discharge the phone battery below acceptable levels?
Any advice on rebooting it (can't remove the battery like I would on a Samsung) so whats the procedure?

Just a follow up charger not the issue, it crashed in use and the power button became non-responsive, with the screen off, and the e-ink display on but also unresponsive. Did not turn on when connected to a charger. However when I connected it to my pc it did register in device manager as MTP device, so I knew it was still alive. Removed the sim and held the power button down for 10 seconds then it rebooted.
Hope this helps anyone else with a similar problem.
Failing that it would probably have to be left to discharge (might take a while if nothing is running) then powered back on with charger attached.

I have similar problem. My phone got hot while not charging (about 15% of battery) and crashed. Then forced reboot (hold power button for about 10 seconds) helped while phone was connected to Yota charger, battery was dead, but phone booted (EPD on, did not check rest) and got to about 81%. After removing it from charger, same thing happened again, no luck with forced reboot this time. Phone was blazing hot and did not respond, then crashed again. No response after connecting charger or forced reboot. Any experience with this issue appreciated.

It seems a battery issue. Have your Yotaphone a valid warranty?

I am not sure about my warranty, bought it off AliExpress, I guess I could try to send it to manufacurer (i heard Russia provides repair service).
EDIT ( t + 2 days): I managed to start my Yota again. I connected it to computer and after about 5 minutes, magic happened and phone started all by itself. I will try to find out more, will update this as soon as I find something

Man, you are more lucky than me, I have a dead yotaphone lying around here. It also died after connecting it to a bad power source.
In my case it was the usb-port of a monitor.
When I checked the usb-port with a cable with a volt/amp display I saw that it was going on and off very quickly.
But so I would say be careful where you connect your yotaphone to, it does not seem to handle weird power sources all too well.

I actually thought about burning charging circuitry a lot. I wonder, if you would be able to test wireless charging. With some luck, it is independent enough to not be affected by burning micro usb charging route (depends where high voltage safety is implemented). If this make any sense to you, please give this a try (I think IKEA is place to go, they should have working wireless chargers in their model setups) and report back. If I am wrong in any aspect, I'd appreciate any correction with explanation.

Sorry for the late reply, did not see the quote, but it does not work with wireless charging either. I think the battery still has a lot of charge too. Thing is that the Motherboard also gets hot after a while when I try to charge it. I'm pretty sure my motherboard is dead. But I have another Yotaphone now, so maybe in the future I will test with every separable part replaced.

I use the charger from my iphone. It works great, although with the yotacharger also works well. Attention that I have a YotaPhone YD201 with Russian base and european compilation. Like I said the Iphone charger works great and doesn't warm my Yotaphone 2 . It might be a solution for your problems with charging.

Slow charge with original charger

Hello,
i'm new here and i'd be glad if someone can help me. So i got my phone a month ago and i noticed that while its charging (with the original charger) and while using it in the same time it almost does not charge at all, still when it's not used it does actually fast charge. As a previous samsung user, i never had this issue with samsung phones (they always fast charged even on heavy use).
That's one problem, the second one is scrolling isn't smooth. Yet my internet speed is 1GB at home although i don't see it related, overall scrolling let's say for example Facebook, snapchat, browser, it gets slow at few times and it ain't smooth like i expected it to be.
My device isn't even rooted so i haven't messed with it anyhow, running usual diagnostics and clearing apps regularly, downloaded just few social media apps so no heavy games on the phone but still i can't figure out if it's just my phone or is it the lg g6 like that.
thank you

1st i wanted to mention maybe the problem is your outlet in house but, yes G6 is charging slower when you use it on your charger.. And when it comes to fast charging to mine it tooks 1h and 40min from 0-100% bit slower than competiton models, but again fast enough.
When it comes on smoothness i am on V10T EU update and the phone has no laggs at all. It did had on past versions. But with this V10T i hadn't had any smoothness issue.. It really is great, and for playing with the phone while charging i wouldn't recommend that. It can really take effect on your battery.
Powered by LG G6

The scrolling lag sounds like there might be something making the phone work hard. Heavy usage would also make it charge more slowly than expected, because some of that power is going to operate the phone rather than into the battery. BUT I don't think it would prevent the "fast charging" text on the display.
It is remarkable how badly-behaved apps can be - I'd remove/disable your apps one at a time and see if one of them is responsible.

Try a fully compliant aftermarket quick charge 3.0 charger, it should charge much faster. Unlike a QC 3.0 charger, the charger bundled with the phone does not include 12V charging mode, so it's not allowing the phone to charge as fast as the phone can handle (the phone is fully quick charge 3.0 compliant and can charge faster than the bundled charger is capable of doing).

Yup, that's true. BUT I have s7 and g6 and both are slowly charging when I'm using them, phone would get too hot if it would fast charge while using it

I appreciate all your replies guys. Thank you.
Although i noted i dont have any heavy apps or heavy usage, the scrolling lag seems like a lag to me because i got used to faster phones before. Or maybe it is the original cable i need to change as you guys said. Anyway thanks again

I also encountered slow charging problems, but it seemed to be the cable, in some position it worked and in some it did not. I've bought an one plus dash cable for about 10 $, red one, and no problems since then. The cable is more thicker and robust, I highly recommend it.

Hi, I've got this problem: sometimes when I plug my G6 to the charger, a popup message comes out saying:
Charging slowly
Try the following if charging is slow:
- make sure to completely remove any water or debris from the USB ports.
- reconnect both ends of the cable.
- use the charger and cable that came with the phone.
Sometimes, instead, the phone starts charging normally with fast charging. If that popup comes out and I try to unplug and plug USB cable a couple of times, the phone starts charging again with fast charge.
Sometimes, when the phone is already charging with fast charge, suddenly the phone stops charging for a couple of seconds and starts again (I notice it because of the popup sound that comes if you plug the phone to USB)
I even tried to clean USB port, swapped the original USB cable with Anker cable but still using the original LG charger.
Of course there is no water in the port, otherwise a moist detector message would appear.
Has anyone experienced this problem? Can I solve buying a new charger? I'm afraid USB port might be broken

I did it recently after I upgraded to Oreo but this was happening even before I did reset the phone.

Yeah i found that funny that LG lied and tried to get by on using the chargers from the failed lg G5 shipped with the G6. They only support 2.0 charging so just use the cord and use another 3.0 block or get a portable 3.0 power pack. They are 20 bucks on amazon. Good ones too.

https://www.amazon.com/Charge-Anker...1528444548&sr=8-3&keywords=anker+powerport++1
can this be a good charger?

I bought an used G6 without charger but I have a Pixel charger model GL0102 and when I plug the phone I cant see the fast charging notification on the screen. It only say charging.

Pro3 shuts itself down overnight

I recently switched using to pro3 from max2. I have a small problem, now i found twice that the phone was completely turned off in the morning.
The charging cable was connected in both cases. I could turn it on by pressing power button few seconds. Than Android boots normally. But normal pressing the button does not turn on screen. I didn't try the fingerprint sensor (forgot)
Also, charging light was off even though the charger was connected. After boot, the charge was 100%
I am using LineageOS 15.1, but I remember seeing a scheduled turn off setting in EUI before switching. Can it be that I forgot the setting on before installing LineageOS. Can that option stick between OS changes? I assumed it should set something in processor to be able to wake phone up from total shutdown?

Were you using the stock charger?

I had issues with a stock charger shutting down the phone overnight I got one good and one bad one. Great phone but the chargers and USB chord are lousy quality. There are a lot of complaints about faulty chargers and USB chord's and lots of replacement recommendations in other Post's

Don"t charge overnight with stock cable.

Although the phone was connected to charger when this happened, I don't understand why you would think that the problem is the charger or cable?
In either case, it happened with 2 different chargers with different cables in different rooms connected to different power outlets. I use the same chargers to charge another Pro3 and also I used them with my old Max2 and nothing like this happened ever with those phones.
Today it happened again and before I restarted the phone I connected it to PC and PC finds the phone as `Qualcomm HS-USB QDLoader 9008` but I am not sure how and why it would go into this mode by itself? Is there a way to debug how phone entered that state?

It's well known that the stock cable can cause various issues, along with burned ports and unexplained shutdowns. The official LeEco forum is gone, but there WERE posts regarding this issue and pictures back in 2016-17.
I guess you weren't on this subforum back in those days, so you missed out on the various warnings. Darkobas and Code suggested that we NOT use them. Users ignored such warnings and as a result their phones stopped functioning properly. This is is very YMMV. Though it's not worth the risk.
You're not the first that has experienced issues, nor are you the last.

@Ace42 Firstly, how will cable cause phone to shut itself down? (actually, as we know now it was in some Qualcomm QDLoader device mode). Can you explain it technically?
I heard about those rumors about cables. To be honest, it feels like somebody was trying to spread FUD. I have bought two max2 phones and four pro3 phones and the cables were perfectly fine. Also a friend of mine bought one max2 and he had no problems either. But I have many cables and chargers because I like to have redundancy and easy access to charger in any room. So I use other cables and chargers. Had no problems with any yet. I am an engineer and monitor the performance of everything I use very carefully. Those cables perform up to specs so far.
Perhaps competitors of LeEco tried to cause panic. Then some people who do not have the necessary information or engineering data blindly suggest something which they can't be blamed for. I have seen it this many times. If you can tell that cable can be used or shouldn't be used, it is 100% safe to tell not use it

Other phones that rely on QC3.0/4.0, such as the LG G6 and Razer phone charge at about half the speed (1800-2100mA). The Pro 3, with the stock charger, will charge well over 3200mA throughout (0-100). It's running out of spec, and not in line with other QC phones.
The Razer, according to owners on XDA, will start over 3000 (until it hits 25%). Once it gets there the rate is effectively cut in half. Again, the Pro 3 will continue to hit 3000-4000 after 25%, and G6 has a constant 1800mA rate. So Samsung and LG phones from the SD82x era shipped phones that charge around 1500-2xxxmA. For some reason the Pro from the same year is much, much faster.
Also if you ask Darkobas (former dev), he'll mention proprietary code for the stock charger. So it's not the same as using Samsung's adaptive charger, or literally any other QC compliant charger. For whatever reason it's able to fry ports (which could be due to cheap parts in the phone), cause the phone to **** off, and initiate QFIL mode.
The last one isn't crazy actually. You can brick an Essential phone by using the stock cable. Now as you mentioned, the phone goes into a special mode (which is unheard of on other devices). That reminds me of these factory cords.
https://www.xda-developers.com/build-your-own-kindle-fire-factory-cable/
https://www.androidauthority.com/essential-phone-usb-c-cable-831817/
What I still don't know is where the problem exists. Is it the phone's board, USB cord, or something else? That's the real mystery.
You raised an interesting point by mentioning competitors. However, I'd rather not take the risk. You're better off using another charger instead of giving yourself a headache.

For the record, before when I most of the time left my phone charged overnight, it would still run fine with stock EUI. Now with custom ROM, this dreaded issue is happening consistently. You won't be able to turn on the phone unless you plug it back and hold the power button for 30 sec or so. And yes I am using the stock charger and cable. No burn in so far since Oct. 2016.

Galactic Stryder and Darkobas worked on supporting the stock charger. It requires additional work.
"Regarding issues with QC 3.0, beware that it has a throttle down mechanism when battery reaches ~40°C it limits input to 2,5Ah and also that it can reach 4,0Ah maximum up to 80% only if the battery temperature is below the threshold for safety zone.
This is the only Kernel using LeEco's charging mechanism with proper safety checks in a minimal manner for ZL1, of course the HW itself can adjust input even without the OEM code in place but it would be a risk to fallback on it without those simple checks.[/QUOTE] - Galactic

Running into this issue too now I'm running aicp, so I guess it's dangerous to use stock charger with these ROMs?

Actually, you are very wrong. Because laws of physics does not allow you to charge li-ion battery with same speed between 0% to 100%. Because the charger can't raise the voltage over 4.35V. Thats why qualcomm always put out figures of 0 to 80% when talking about quick charge. After ~80% charging process will slow down whether you like it or not.
You have spectacularly failed to explain why a cable can technically cause this issue on this phone. I recommend you to first try to understand why something is happening instead of quoting random people's thoughts. There is no guarantee that the people you quote know what they are talking about to begin with....

No reason to be worried, stock charger has nothing to do with this issue. Also stock charger works perfectly fine. @Ace42 simply does not know what he is talking about. Spreading FUD, you know?
Actually, in my device I even limited maximum charge voltage to 4.2V (only charge up till 84%) and it still turns itself off sometimes when connected to charger, even when the phone stops charging, also with different chargers and cables. Even with USB-PD chargers with type-c outputs and type-c to type-c cables. This clearly tells me that the issue is nothing to do with charger or charging voltages or charging speed, or cable. Also here it was mentioned that this did not exist with EUI and somebody who used LOS 14 says he didn't have it until he upgraded -> https://forum.xda-developers.com/le-pro3/help/los-15-1-zl1-leeco-pro-3-x720-shutting-t3846441

thats me who was mentioned upgrading from LOS 14.1. I have a detailed description of my issue in the thread that was linked above.
never had any problems with the stock charger. And my phone turns off when i am not using it for several hours, unrelated to it charging or not.
seems to be related to deep sleep I guess?

I have exactly the same problem. The phone turns off twice a week twice a week. An alarm does not work. Daughter is late to work .
