phone only started doing this over the last couple months, used to be able to plug in (either charger / cable) and charge in AC mode without supervision.
Nowadays, it takes several plug in attempts to even START in AC mode, but typically it'll drop down to USB (the screen comes on momentarily when the change occurs) at some point in the charging.
Worst case scenario, it'll change rapidly back into AC and out, to the point where I can watch it on happen on the screen. That's rarer though.
It never changes INTO AC and stays there, to be clear. Always a downgrade to USB charging.
Is something wrong physically with the jack on the phone? I've never damaged the phone, dropped in water, etc.
If RMA is what's suggested as my only option - is that a brand new phone or refurbished?
Use another USB charger, its a known problem with the supplied LG charger with the N4. I myself have this problem but am using another charger and its fine.
The USB cable has no problems btw, its the charger itself.
Can you link to your sources on this being a "known problem" ?
I'm pretty sure the same issue persists with my old Samsung charger too - the one supplied with the Galaxy Nexus. So.. that suggest the problem is with the phone, not the charger/cable.
i also have the exact same problem just now.. i'll try using another charger tonight at home..
just now i charged my nx4 using its original charger, in just a couple of minutes, the phone is saying that its being charged using usb.. stupid..
I'm also getting this at the moment, I'm completely stock, not even rooted and this has cropped up only since the 1.8mb Security Patch....
Any fixes?
Will root if I can fix it....
I was/am having this issue as well. I typically charge my phone via car charger (works fine) or wireless, so I can get around this issue easily. Plugging it into the PC and enabling fast charge with franco's kernel works as well.
I tried my N10 charger and it was dropping to USB as well. When I'm at my friend's place and use his generic charger, it works fine.
I used to have this issue but ever since I updated Android to 4.3, my charging works just fine.

Might try a factory reset and see does it make any difference...
do we have any more thoughts on this issue? is it a software bug? is it hardware? which hardware? I am going to experiement with a few different wall chargers and usb cables.
so 3 chargers (Galaxy Nexus' , Nexus 4's, USB 3.0 port on PC) and 3 cables (likewise + cable from monoprice)
SEEM to yield the results, that the problem is the connection between the cable and the phone. The oldest and most used cable has the hardest time establishing and maintaining an AC connection, the newest/lest used one from monoprice has never had a problem, and the LG cable is in the middle.
Is this an issue of wear and tear on both the cable connectors and the phone's port? It's really lame the phone and it's cable are not even a year old and THAT can't stay charging at AC voltages.
Will a replacement phone from Google be a refurbished unit or brand new?

They will send you a new (not refurb) phone and you will have 21 days to send back your old phone. The replacement process is super easy, just call them at +1 855 83NEXUS and tell them your issue. They will walk you through a factory reset and if the problem is not fixed they will replace it.
I've had issues with the microusb port on multiple phones in the past, and have definitely noticed the N4's socket getting looser.
On an old HTC sensation, I had to resolder the port on. Can you reproduce the behavior by applying slight pressure to the plug in various directions?
Does your connection also intermittently drop out when connected to a computer?
A workaround for the time being could be to use a kernel that allows you to force fast charging regardless of the detected charger. But at that rate, it's quite possible you'll lose your usb port altogether sometime in the future..
You could also enable adb over wireless, and check the charger type:
Code:
cat /sys/kernel/debug/msm_otg/chg_type
You should be seeing DCP (has the data pins connected, possibly with some resistance).
Or proprietary if you're using an Apple-compatible charger (has aspecific voltage on the data pins).
If you see SDP, it means it's in "USB" mode.
If it's staying DCP/proprietary but the charge rate is dropping to "USB," it means the phone is throttling down the current because it's detecting the charger can't deliver (voltage dropping below threshold).
with the good cable (monoprice), wiggling has no effect.
with the poorest cable (samsung), wiggling will rapidly change it between AC / USB / nadda
with the LG cable, wiggling, will SOMETIMES have an effect. sometimes it's solid and will only become a flaky connection after it's been charging a while already
Recently my OP2 doesn't seem to charge properly. Meaning...with the USB cord connected to the base it charges for a min then stops. The light stays on as if it's charging but it's not. I have to unplug it and plus it back in and it's fine for a few min then it stops and I have to do it again. This just started happening. I haven't dropped it or anything. The charge port is fine. Anybody else have this problem or HAD this problem...any info would help...
I have this exact same problem with my less than a week old OPT. I think its the charging cable gone bad. Using Ampere to check the charging current, I find that it never goes over 200ma and after about a minute (or lesser) disconnects because the software cuts it off when the current is too low. For now, charging with the phone turned off works, since no software to cut off the charger, but I do not know if this is bad for the battery. I am trying to find another Type C cable now, see if I can confirm this. Will post back if I do.
UPDATE: Was the cable. Friend's xiaomi cable worked perfectly and charged my phone back to 100% while I had dinner. Amazon is giving me a free replacement, so not complaing too much ...
Lately I've been having issues with my phone and charging. It started with the stock OEM charger getting steadily harder and harder to use.. so I bought an Aukey charger to replace it with and it completely refuses to work on my phone, so I tried another phone and tablet and it works great. I tried my super old Galaxy note 2 charger with a motorola usb cable from my maxx and it works fine... I then tried that usb cable on the aukey QC 2.0 charger and it won't work... tried the same cable again on my phone with the sammy charger and it worked... tried a QC 3.0 aukey wall charger and it won't work... yet I have a QC 2.0 incipio car charger. it was working with the USB moto cable I've had in my car since I got my Bionic... then it just stopped charging my phone, got a new USB and it works great now except the moto usb will work for friends, just not my phone.
I have absolutely no idea what's causing this... I thought maybe there was lint in the charging port so I took a tootpick and cleaned it out, got a small piece of lint, same thing with all the chargers. I can't find anything online, and being a tinkerer I've tried everything I can think of before asking. I'm starting to think the phone itself is having problems and the port is actually bad or there's something wrong in the software causing it to have problems with turbo or QC chargers.
any ideas?
There is a general inconsistency with this device and Quick Chargers... if you look in the Accessories area there are several threads discussing it.
Personally, I use the Aukey QC 2.0 charger for travel with an Eversame premium braided cable and it works fine, yet others use the same combination and it won't Turbo charge or in some cases charge at all.
I also face the same issue. Some USB cables work with my Moto X Style and some doesn't .
i am having an even worse issue and i am sure its a software problem, recently my moto x stopped charging using the moto charger so in the last two months i have 4 different chargers who worked for some time each now it just doesnt work at all, i have cleaned the port numerous times then it just stopped working so when the phone finally died all of a sudden it started charging but as soon as it switched to turbo mode the charge would stop and start over again. i have deduced its a software problem as once the phone tries to go to turbo charging mode it cant sustain the charge and cancels it. amphere even shows its discharging while on the charger , however if it starts charging while the phone is off with a low voltage adapter and turn on the phone once you dont remove the cable it will charge (extremely slowly but it will charge).

FYI... There is no software problem with charging, if there was it would affecting hundreds of thousands of people. And I doubt you have 2 software problems, a bad kernel and a bad bootloader/recovery image, because 2 different things control charging when powered on and powered off.
Issue here is you likely have a high resistance connection somewhere between the USB port and the battery itself, or a bad charging circuit... It's hardware.
while i can understand where you are coming from when the phone is in factory mode (motorola customer care told me to try) its charging fine also turbo charging is working now just it doesnt recognize the sim card. it was a suggestion from Motorola customer service desk, as i live outside of the us they gave me some options to try. they said it was a software glitch where the phone may have gotten an overload from a bad connection and caused the phone to not recognize the charger. however while the phone is off this check is not performed which is why i was getting a lower amp charger to work as the phone did not have to enable the protocol that allows for quick charge/turbo charge voltages.
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.
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.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 .
