Wireless charging issue - G3 Q&A, Help & Troubleshooting

I purchased a used G3 (Sprint) a couple of weeks ago, and the phone has been functioning fine to date, except for the wireless charging. I purchased two separate QI stickers and wireless charging pads via ebay, and all combinations are having the same effect- the phone will recognize the wireless charging, but immediately power off. If I have the phone off and place it on the wireless charger, it'll boot up the phone and then turn it right back off. I've tried multiple cables, chargers, and it's the same thing every time. I've done some searching online and can't seem to find this problem replicated anywhere else.
The phone charges fine when plugged into a conventional charger. I'm not sure if this is a hardware or software problem- I've yet to do a hard reset on my device to see if that changes anything.
Has anyone seen this happen, or have any insight? Thanks

Bump...anybody?

...
I am charging over LG wireless charger (WCP-300) and tested on nokia Qi charger (dt-903) with no issue. Tray with different Qi charges. If it do again make hard reset. Tray maybe to replace the back cover to borrow for some one who has same phone and make test. If it does not work send phone to service.

which wireless sticker did you go with? did you need to add the padding to get the correct connection?
Mine did this after 2 days. A couple of us talked about it in the other thread. No solution was found. I asked for a refund and an waiting for another from a different company

cant remember the name, its from aliexpress, a Hong Kong seller
Hmm...
This happened to me with a case which had the nfc/qi sticker on the back (from amazon). The wireless charging worked for a few days then stopped. The case was a yootech quick circle case from amazon. Not to speak poorly of them... Their customer service is excellent, and they shipped me out another one. But amazingly... The second case had the same issue. Most reviews on amazon were 5 star so I seemed to be in the minority.
If this happened to you, did you eventually find a sticker/case that worked (longer than a few days)?
Also, what specific model do you have? Mine is VS986 (Verizon). Gray plastic back, from best buy...

Mine is 815 I'm using here in the states. I have ordered a different one, but shipping is taking forever. All the other stickers appeared to be the same as far as I could tell. So, no, I haven't found one yet; but hopefully in a week.
I have this problem, too. Weird thing is, I have also bought those stickers, but I don't think that is the problem. I also have the original LG circle case with the built-in wireless charging, and that stopped working, too?!
I had this issue a while back when the stickers first came out, so I bought another from a different manufacturer, but it had the same problem. I bought an official LG quick circle and it didn't work either. It was the phone not working, but the sticker or case. I had to send the phone back. Lucky for me they refunded me after a month of owning the phone. i was getting sick of the bugs and lack of root anyways. But now im stuck with 2 stickers, 4 cases/bumpers and an extra battery lol. Oh well.
Anyways, point was the phone is faulty. RMA time if you really want wireless charging like I did.
Thank you for the info frigidazzi , I was afraid that it was a problem with the phone, and not the stickers or cover. I guess I will have to send it back then... Bummer...
Same experience
I have the Verizon LG G4 running stock with no launcher. I purchased the New wisdom qi sticker from Amazon and after installing it had no issues charging wirelessly on my Tylty charger. After several days, my phone stopped charging, and no longer recognizes the charger when placing the phone on it. I assumed that the sticker had an issue, so I ordered a new one, but after installing it the phone still will not start charging.
The Tytly charger does recognize the phone when placed on it, but the phone does not recognize the charger. This has been driving me nuts since it was working fine for several days and now nothing. I also have a qi charger in my car and experienced the exact same thing.
guys, it's a hardware failure by the looks of it, please read here http://forum.xda-developers.com/showpost.php?p=62403976&postcount=9
Ugh, say it isn't so
That is probably the worst possible news, but thanks for sharing. Has anyone had any luck returning their phone under the one year warranty to get this fixed?
I also installed a Qi Sticker on my LG G4, at the beginning. I was having a lot of trouble, I even added a little bit of padding for the connections but when I tried to charge the phone it would always disconnect.
The solution was very silly, apparently the dock station requires an adaptor of 1800mA (or above) to work properly and my adaptor was for 1500mA, and now it works perfectly.
So yeah, check all the connections and the current values for the devices.
btw. Also check that the two conntact pins for the wireless charging sticker are springy.

I just checked the specs on the TYLT VU charger and the input voltage is 12v/750mA which is quite a bit lower than the charger you are using. Even if I could find another wall adapter that would fit into the VU, I would be leery of doing so since that would be more than double the voltage for which it is rated for and I don't want to trash my $60 charger. I also used this same charger with my LG G3 for over a year with no issues at all. As I stated earlier in my post, my G4 was charging fine for several days and then stopped suddenly (others reported similar issues as well). Lawrence750 mentioned this post: http://forum.xda-developers.com/show...76&postcount=9 which seems to indicate this is related to the phone itself (hardware failure). Until someone is able to send their phone in to LG for repair and then receive it back with the problem solved, I don't think we will really know for sure what is causing this issue.
I had an issue where the phone also stopped charging wirelessly. I verified the charging array was good and that the phone was seeing it properly. The phone would act like it was going to charge for about 15 seconds then stop. I figured the array had moved a bit and wasn't touching the pins consistently. I placed a piece of scotch tape doubled over under the pin pad and still no joy. come to find out that the spare battery LG sent me was the culprit. Swapped the battery and it worked like a charm. Both batteries charged correctly when plugged in. Not sure why the newer battery had an issue.
I've experienced a problem with my G4 which suddenly stopped charging via wireless. I have a number of wireless chargers which all work with my wifes G3 but I no longer get any response when I try to charge the G4.
I sent it to LG who took 2 weeks and returned it with 'no defect found'. I've obtained another case with the wireless sticker but still nothing. NFC is fine on both cases btw.
LG then sent a spare battery but it still doesn't work.
I'm now waiting to see what they suggest. I could really do with testing both my cases on another G4 to be sure they are ok but the first worked fine for a couple months and theres no reason why a brand new one would also be faulty.
Fixed My Problem
The problem is definitely the phone itself. After trying multiple chargers and different Qi phone battery covers, I contacted Verizon and spoke with there tech support about the issue. They agreed to replace the phone since it was still under warranty, and the new phone they sent me charges just fine.
Mines gone back to LG again. If it isn't fixed this time I'm going to look to return it and switch to HTC or Samsung.,
For any who have tried wireless charging, I have a poll and questionnaire re: your experience. Would greatly appreciate your input.
http://forum.xda-developers.com/g4/help/tried-wireless-charging-t3227672
Got my G4 back from LG with a new main board. Wireless charging seemed to be working. Phone charged wirelessly overnight and since then will not work again.
So I've reached the end of the road with it. I could live without wireless charging but I shouldn't have to so I'm going to push for a refund and will switch to Samsung or HTC. There's obviously a fault with wireless charging looking at the results of Waylo's poll.

Wireless Charging Woes

Ok, so im using the Spigen Neo Hybrid case, and when i use wireless charging, it may work 30 seconds, or 10 minutes, but it always stops. What happens is i place it on the charger and it indicates its charging. Then, within a short time period, the light on the charger starts flashing to indicate charging isnt working properly, and the screen comes on and says wireless charging paused.
I have 3 different Samsung chargers, a Nokia charger and several Powerbot chargers. One of the Samsung chargers is the newest (not fast) chargers. I take the case off and it seems to be fine. Anyone familiar with this case knows its not thick by any means. Also, i have 2 GS6s in the house both using Neo Hybrids and they charge just fine. Ive adjusted positioning dozens of times but i know from experience that most devices dont require an EXACT placement.
I went to Best Buy, where i purchased it, and this is where it gets odd. They placed it on their display charger in the Samsung section and it charged for 10 minutes no problem before they told me they couldnt duplicate the issue so they wont replace it. I brought it home and the damn thing charged to full charge no issue. The next day when i placed it back on the charging pad, it starts cutting out again.
All my chargers have been tried over USB, and yes, with multiple wall plugs. My first thought was not enough power over USB but clearly thats not the case.
Any ideas from anyone would be great.
I don't have the issue with the old wireless chargers it seems. I think it is just the new ones that were given out that I have the issue with.

I've finally fixed my issue with the original samsung charger and generic from ebay, I turned on day dream and it works now without disconnection.
A lot of people are having the same problem and so was I.
Grab your phones charger and base and use that.
I think the long cord that comes with the wireless charger is causing the issue.
I'm using an old knock off wireless charger and no case yet, but it seems to be working fine. Once the defender case comes in, we'll see if it is still functional
I haven't had any issues with my Samsung wireless charger. I'm using the original hardware that came with it. I'm also using the Neo hybrid case. What is your model number? Mine is EP-PG920A. When I was at best buy they said they had two different versions of the wireless charger. Unfortunately bestbuy was sold out so I bought mine at ATT. And I don't have daydream enabled.

G4 Charge/USB port issues

I've had my G4 since almost launch day and within weeks the supplied USB cable stopped charging the phone. I thought it was a cable problem, but it worked fine with other devices.
I tried other cables with the G4 and these still charged it so I thought nothing more of it until charging degraded with every USB cable I own to where the phone would only charge 20-30% during an overnight charge and the phone would frequently not recognise it was plugged in at all. I contacted LG who did a repair under warranty and all was fine.
I've now had the repaired phone back for about 3 weeks and the same problems are starting up again and it's only a matter of time until I am forced to return again for a repair.
Is anyone else having similar problems? I thought I may have just had an unlucky manufacturing problem, and the LG reps confirmed that to repair my phone they basically replace all the internal circuit boards and components rather than just replacing the individual component that is faulty (in this case the USB/charging port)
Basic debugging includes asking stupid questions, so please forgive but still answer any of those
Are you using a different charger? If so, check if that one is within specifications and if you do send in for repair again, use a different charger.
Are you propping up the device at an odd/weird angle or in a dock of some sort with the cable attached?
(As they replaced the entire print, it's probably not this, just the USB-micro port bent or broken.)
You could double check the wall outlets being used, there might be some kind of electrical problem there.
Either using all kinds of fancy electical testing gadgets, or stick a USB light into the hub or charger, does it flicker?
When sending it back for repairs, did they check the stock charger as well?
Hopefully these questions help you find any logical or plausible cause.

Hi FreezyExp,
1. I am using the standard charger that came with the phone, but this has not been repaired/replaced. I have tried other chargers too, but all the same issue.
2. No weird propping up or anything like that. If I hold my phone while it is plugged in it is constantly vibrating as the charger connects and disconnects, and if I place it on the desk to charge I have to ensure that I have at least 3-4" of cabe "on the desk" to give it enough support to make the connection.
3. Wall connection is fine and I have tried it with a range of outlets around the home, both with extension sockets used and plugged directly into the wall and there is no different. No flickering light when using a USB light either.
4. When I sent it back all they asked me to return was the main section of the handset - so no battery or rear cover, no cables or chargers etc
It does seem to be the same issue as last time, a USB connection becoming loose from the main motherboard, but it seems weird that I have had the same issue twice in the space of 4-5 months.
I've been having some sort of problem with my G4 usb port. If I plug it in to a computer, it will lose connection and get a connection again if I barely touch the end of the cord at the phone end. I've tried many different cords and different usb ports on my computer, but it still has problems.
I can't fast charge, either. When I plug it in to fast charge, it actually starts discharging even faster. I've had some extreme battery life problems, too. It drained from 100-36 the other night with everything disabled, and it's been doing that kind of thing a lot lately. I'm guessing that the charging port is what's messing up my battery life because it won't charge correctly.
Never dropped it or anything.
I got my G4 on January 24 and my USB port has also failed. I am getting a replacement from Verizon, but am concerned that a six month old phone has this issue.
I also own a G4 H815. A while ago the phone started not receiving any charge from the cable and I would have to prop it up from right under the cable's micro usb end. Thought it was because it was bent inside the port and not making connection with the cable so I had the port replaced. Now I'm experiencing the same problem and I think it might be the cable that's already gone kaput and is effing up the port itself. I took the phone to the same place to get the port replaced again and bought new cables (I lost both the original adapter and the cable, which were charging slow anyway. Now using a 2A Asus adapter which works great) and when I asked the guy at the repair shop, he says it's a chronic issue with G4 devices. I don't really understand how it would happen twice in just a few months even with a new charger port. What should I make of this? Did they replace my port with an already faulty one, cahrged me full price and now trying to sell this bogus or am I really doomed with this phone?

Charging Port !

Hello, So for past the month i am having problem with my fire phone. I live in Pakistan, Lahore so i bought it when it was not so famous and i did not get an original charger with it. I got LG Charger. But i was not at my house and i was at my cousin house and i had a small wire so i connected my phone with it to wall charger but my phone was hanging i charged it from there for 10 - 20 minutes (MY BAD). So i left my lg charger at home so at my cousin house there were couple of chargers and i used Lenovo one. Now i have been back and my lg cable was not working. So i started to search for cables and i found one that worked with my phone and it was giving pretty quick charge. Now lately it is not even working. Just flashing the screen with charging / not charging. So i tried wire of samsung and it worked! But i have to force it properly into port. So i am in pakistan and i dont think i will find a charging port easily. I wanted to know if the port is bent only or it is partially working can i just take it to repairing shop and have them remove it and place it again ? Properly ? Will it work or not ?
I think your charging cable doesn't have some pins in his head, you should try to charge the phone in fixed position, don t move the phone, try more position, move the cable's head when is connected, left and right.
I am having the same problem

Quick Charge 3.0 and USB C not working

So charging is extremely slow now: max 280mA showing in Ampere app. Tried different cables and chargers(QC3.0 certified), charging speed remains the same.
I can't connect to PC anymore. Windows doesn't even make a sound when I connect the phone to PC. Showing no device.
Headphones connected to USB port are playing only one audio channel.
I've been using LOS 15.1 since last summer without problems, haven't done any updates since. The problem with USB port emerged a month ago and I am almost convinced it's a HW issue. AIDA64 indicates no temperatures over 36°C in thermal section so sensors are working fine I guess.
Anyone tried these charging ports from Aliexpress? Comments indicate that they are not the same as the original.
It really sounds as hardware problem. I asume you already tried with the phone off, and after factory reset and the problem persists.
In my experience, the original lower board have fuses which are expensive and are replaced by resistors on chinese replacements. If you dont want to lose this, try going into a repair shop and have the USB-C port replaced or desoldered/resoldered from the board. Must be done by experienced guy or it will be melted.
I'd buy the replacement board anyway. As long as you don't use crappy chargers, you shouldnt need the fuse too much, and also, the phone have another fuse in the motherboard.
If you have not tried with the phone off, try it. I got the xiaomi wireless charger and it works like crap with the phone on. it disconnects/maintains chage/stops charging A LOT, but if I charge the phone turned off it charges without issues at full power (8-10W according to my USB meter). Maybe is just the firmware being an ass
Thank you for insights. I confirm that hard reset nor charging solved the missing QC3.0 functionality. It's clearly a HW issue.
The whole situation was caused by losing my original charger on a trip and then using certified QC3.0 charger (not from Xiaomi) and unfortunately - cheap Chinese micro USB C cable. I can't stress this more... Never use cheap cables (or chargers) they can literally fry up your port. In this case it was definitely the cable eventhough it worked fine for 5 months.
It seems (from comments) that beside fuses the charging ports from Aliexpress are missing the possibility to transfer data over USB as well. Which is not that crucial because FTP over WiFi is bearable. The real problem that I need to fix is quick charging because with 280mA on Ampere app it takes 5 hours to charge this phone.
The charging port I've bought on Ali is on its way so I will update this thread in a few weeks after inserting it into the phone.
Losing data over usb is quite a problem if you are into custom roms/mods on native miui (which resets the recovery on each update).
Hope that ali's board does have this funcionality. About charging, you can get locally a wireless charger for now, though for me it only charges fast when the phone is idle, using it always just keeps the charge (probably to avoid overheating).
So how the story ends? We're you able to solve the problem?
I had the same issue with my Mix 2. bought a replacement port from Aliexpress and Witrigs.com. As posted on most forums these replacement ports don't support fast charging (in most cases) and no USB data transfer (this is the case with mine).
I had dropped a message on the witrigs.com website to confirm if their supposedly 'OEM' replacement supports data over USB (it looks much more like the original board in the phone that the 'custom' replica one that is half the price).
but I'm not very hopeful of that being the case, given someone has already left a comment on the product page indicating they bought the OEM version and faced the same issue with no quick charging or USB data transfer
Got some problem when i lost my usb travel charger on a trip.
and now my phone was too slow and cant transfer data even if i buy the new authentic from xiaomi store.
i hard reset for 3 times and but no luck.
omg -___-
I know it's old, but I'll let you in on my problem.
I have the Mi Mix 2 and it was happily fast charging until recently. Still the original plug and cable
I have tried all sorts of theories to get it fixed and one person said to charge it while turned off
So I plugged in my usb cable and turned off my phone. Only for it to automatically fire up and go into fastboot. No charging. Just fastboot on the screen
Obviously I can get out of fastboot mode again, but is mine an option change in the settings that needs addressing?
Thanks
