Many of you will think this is bonkers at first read, but I want to know if anyone else is experiencing this as well.
Scenario:
Take off any covers or cases you have in your phone. Make sure all the protective shrink wrap around the phone is removed.
Plug the phone to the charger like you normally would.
With a single finger, gently run it along the sides of they phone (on the casing, not the screen). Run it from the top to bottom. Either side of the phone.
Does anyone feel a weird buzzing feeling on their finger ?
Remove the charging cable and try out again. No buzzing feeling.
My Redmi Note 4 has this issue. I don't know what it is but it feels like small vibration.
Yes, I've felt this for years on different devices with a metal body. Weird isn't it! I've never looked into it.
What country are you in? This is a grounding issue I've experienced charging phones when overseas.

220v countries. Voltage leak to the casing. I got this when converting to 110v. 1+ phone in my case
Mine seems to be fine. I don't get any vibrations on metal frame on my fold 3.
Your charger has a grounding issue. Many years ago the same thing happened to my iPhone 6 when I used a cheap USB charger. When it’s plugged in I can feel a weird tingling if I run my finger up and down the sides of the phone, and the fingerprint sensor in the home button stops working when plugged in. The issue disappear if I plug it into a different charger.
I don’t think poor grounding will damage your phone or injure you, but if you can afford to I would replace the charger just in case.
The chargers are not grounded so it's not a grounding issue. Rather, the EMI suppression capacitors in the power supply (charger) are designed to couple to the line wires. The sensation comes from 220V/50Hz being capacitively fed into the USB ground, but the current is only a few microamps.
There's no easy solution to this but:
- ignore it
- try various chargers
- ground the USB ground to the earth ground
- take apart the PSU and try different capacitors or remove them.
In the US, and I have this tingle when its charging and stroking the spine with my finger. Our plugs have no ground. They are polorized but don't have a third pin. So not sure grounds are at issue.
It is similar to the feeling from one of those lightning globes, but a bit more intense. I was thinking it is some charged particles that leak through the spines plastic. It is an interesting feeling not really unpleasant. Would think it's harmless but it is interesting.
I tried EVERY SINGLE CHARGE I have and found 2 "cheap" ones that had this issue. I tossed them and all of my genuine Samsung ones were fine. As well as the other ones that came from various phones that were not knockoffs.
I always feel it on every phones and laptops with aluminium even with their respective official chargers.
Totally normal. if I have both my laptop and phone charging and touching them at the same time then this happens, but it can be negated by switching the figure of eight plug on the laptop charger to match the phase of the usb charger
I believe it might also be due to the Neutral and Live wires being reversed either in the charger or at the wall socket.

I've noticed that the connection using the micro usb cable is not snug, if I apply slight leverage to it the charge/connection is lost.
Im a bit dissapointed because I have certainly not pulled on the lead/dropped the device while attached or anything else that might have buggered the plug.
Is there any way I can make the connection snug again, or is this typical for all other devices too.
If this does turn into someting more problematic what are my steps to get it fixed, I brought this phone as an orange locked unwanted upgrade from ebay. fully boxed and sealed. (i.e. new)
Im a bit annoyed because the micro-usb plug is supposed to be more robust than the mini-usb. but to my eyes that not the case, and has proven to be not true either.
I have this issue too. Interested to see if it's a common flaw.

Same problem here. Just got it yesterday. The loose connection is very annoying in that you cannot be sure you left in a charging state unless you unlock it and check the screen. I wonder if it supposed to be that way?
After having posted this, I realize that the thread is not for my phone, a Samsung Captivate. I trusted Google search a little too much I guess. Interesting that the problem is the same.
Same here.
Xperia X10 with a loose connection that got much worse with time. I don't expect a fix for a hardware issue, but I am taking it back to the store for a replacement. The problem is that it has gotten so bad that I can't maintain a connection long enough to get my data!! Not pleased

May have to return to T-mobile as its really annoying
I have the Captivate, and I had to exchange mine for one that did not do this.
Yep I started getting this problem a few days ago. Pissing me right off.
can someone tell me if the Samsung captivate and Xperia X10 both have micro-B USB ports also ?
Micro USB Sucks
I have the HTC Incredible and whenever its plugged into my PC you can tell by the audibles (and by HTC Sync failing 1/2 the time) that it keeps disconnecting and reconnecting - especially if you lift the phone or move the cable. So I was just as surprised to hear the MicroUSB was supposed to fix some of the wear and tear issues of MiniUSB - which is just untrue!!!
My HD2 has a loose connection
http://app1.appserver.dk:8080/RepairPictures/servlet/getPic?id=51371
<-- This is the chip. And HTC wont repair it. They say it's my own fault? :S
I've got this problem too with my desire and realised it's the cable. I got my desire on the release date (had it preordered) and the plug on the cable is smooth on all sides so it slips in and outu the phone easily. However, my girlfriend got a desire 2 weeks ago, and the micro-USB plug on her cable has two little spring loaded bumps on it, which gives it a positive "click" when it's plugged into the phone and it takes a lot more force to remove it.
Hence I stole her cable
My cappy too
This problem is happening, albeit not as seriously as some of yours, to my cappy now. I have had it for just under a year now. Looking back I could have been a little gentler with it...
Running Teamhacksung's ICS Build 9.
I've got the same issue - turns out that it's the cable more than anything, as when I plug the in-car charger one (a different cable) in, everything worked perfectly.
terrible design
Every device I or my wife has that is micro USB has charging issues. The design in a laboratory is supposed to get 10,000 cycles. But our experience is that a device after 6 months starts to have issues. Finally after a year about every device must be replace as the charging port is so loose that not even the highest quality cables will stay seated well enough to guarantee a charge or data connectivity. Very disappointed that EVERY phone uses this. Well other than Apple, which I may just have to go to since I cannot afford new phones constantly. The wireless companies KNOW it is a flaw in the design of the port also. Not a one of them will warranty the phone if the issue is the charging port. I am talking clean ports here also. No lint or anything.

I agree, micro USB is horribly unreliable across all brands. Too bad I absolutely loathe iOS, because I would consider getting an iPhone if I could run Android on it. Hopefully USB Type-C will be better.
5 data points and a question
First, additioanal data points:
I've had 2 different devices with micro usb connectors and both failed within 3 days of beginning to use them. I can't swear it was the female socket that was damaged but that was my impression. The prongs on the male connector were NOT flattened. I looked for that.
I had another device, a Nook Color I believe it was called, that had a usb charging/data connector that was their own slightly modified design of one of the usb standards. I can't swear whether it was a modified mini or a modified micro but I think it was a modified micro. Anyway the socket was a little deeper than the standard. The idea was that if you plugged in a standard male connector it worked the same way as a standard socket but if you plugged in the longer Nook male connector it went in deeper (I'm straining to refrain from low humor here), additional contacts came into play and it would charge faster. In the Nook case it was definitely the male connector that would break. I replaced the charger twice before the Nook failed for other reasons (I suspect a cat baptised it). If you search the net you'll find a lot of people had the same problem.
So in my case micro-usb is either 2 for 0 if you don't count the Nook, 3 for 0 if you count the Nook once, or maybe 5 for 1 if you count the Nook replacement chargers and charitably assume the last one would have worked for a while if the cat hadn't scented it.
I've NEVER had a problem with large, plain, standard, type A rectangular connectors. I think the idea that the mini is too big is one only Madison Avenue types could come up with. Even the standard type A isn't really too big. After all, how big is a thumb drive? I suspect it has more to do with making it a wee bit cheaper than making it smaller.
So yeah, micro-usb just plain sucks. Assuming Frank's posts in this thread at stack exchange:
electronics.stackexchange dotcom /questions/18552/why-was-mini-usb-deprecated-in-favor-of-micro-usb
aren't fraudulent, Nokia pressured the USB Implementers Forum to accept the micro standard, implicitly against the better judgement of some people involved. I'm therefore inclined to never buy a Nokia anything.
So much for the problem. I'm thinking about workarounds because there is a tablet I'd really like to use that charges through a female micro usb port. If I can't charge the battery it's useless. So I'd appreciate comments regarding the feasbility of these alternatives:
WORKAROUND # 1:
Carefully insert a male-micro-usb-X-female-standard-type-A adaptor into the device and glue them both to a piece of waterproofed luon (very light plywood) and then connect with a cable that has male standard full size rectangular type A connectors at BOTH ends. I've never had any problem with the standard full sized type A and they are easy to replace if I do. Though both adaptors and cables as described, are readily available, it is said that the maleXmale cables can damage equipment in some cases and I'm don't know enough to be sure this is not one of those cases.
WORKAROUND #2:
Alternately I could just glue the micro end of the kind of cable that comes with such devices to the luon and leave the rest of the cable dangling. Downside: Messy dangling cable. Upside: I KNOW it is safe.
Any thoughts on these workarounds would be appreciated.
My charger doesnt fit well and i just came to terms with this but it has got worse the last two weeks. It plugs in and the led lights up but it doesnt charge sometimes, it says it is charging but an hour later and the battery goes down 5% ish. Also it only connects when the phone sits face up and the cord hangs down as in it must sit on the edge of the table for it to charge. I tried my friends Droid cord and it was a snug fit. do i have an insurance claim on my hands?
You can try getting the cable swapped, but honestly I think the amount of hassle you would go through would just not be worth it. If the problem was with your phone then I would 100% definitely get the phone replaced, but if the problem is only with the cable, I'd take the path of least resistance and just buy a new cable out of pocket. They really aren't expensive if you know the right place to get them.
I use this cable here with my Aria and it works great: http://www.monoprice.com/products/p...=10303&cs_id=1030307&p_id=5458&seq=1&format=2
It is only $3.13 shipped (to my address), and it's 2 feet longer than the original cable which I like because I thought the original one was too short. Never had a problem with it charging my Aria. I know it seems too good to be true, but the quality really is just as good as a $20+ cable you'd find at a local store.
I ran into the same problem with an Aria I bought off of Craigslist. It would kind of charge at first, then it gave up altogether. I found that the end that plugged into the phone had been slightly squished by the previous owner. I just went to Staples and bought a Staples branded MicroUSB cable, it's six feet long and works fine. Granted, it wasn't ebay-cheap but I got the problem handled same day, no screwing around. The nice thing about this cable is it's just as flexible as the original, unlike the MicroUSB charge/sync cables that come with Blackberry phones and the extra length makes it a little more versatile.
Don't mean to resurrect an old thread, but I didn't want to start a new one.
My connection is getting worse every day. It is very aggravating. I'll plug in at night time and wake up to find my phone didn't charge at all. I have to put the cable in at a slight angle to get it to connect.
Using adb and just any file transfer on the computer is almost impossible.
I use the original cable, and sometimes my brother's Captivate cable--both are just as bad.
And the AT&T car charger is a joke. So I think it is the phone, not the cables.
i find that the motorola(backflip) usb doesnt fit snug(still charges & transfers fine, a little slower)
May be just a bit too rough with this little phone
Finally had enough of the cable problem, so I decided to figure out whats wrong. Turns out, I ended up pulling out about a cubic centimeter of dust and lint from in the port (way down in there, a quick glance and it didn't look as bad as it really was.)
Works like a charm, now!
Brivette, glad to see you fixed your issue!
For future reference,
The MicroUSB cable that has become the new standard contains 2 prongs on the end of it. This prong is responsible for ensuring it stays locked into the connector.
The newer MicroB connector is rated at a higher use cycle than the old MiniB type, which is why current devices are moving to it as a standard. It is also designed so that the cheaper cable will bear the wear and damage, rather than the device. The usual culprit is the two latch pins at the top of the male connector which tend to wear and bend eventually causing the cord to become "flaky" or fickle (for a lack of a better term). This is usually the cause of most people's woes. However often times the connections from inside the cable may wear and short out, causing the cord to become dysfunctional. Before sending your phone in for a replacement, I highly recommend trying a second cable.
If changing the cord doesn't work, the problem most likely lies with the phone. While it is possible that the PCB mount has come disconnected from the board, it is more often than not likely that the port has become clogged with debris. So before sending your phone in for service, check the port and ensure that the port is clear and clean of obstruction.
This also goes for charging or data transfer. Sometimes issues with data transfer can arise out of a bad cable. This often happens when people wrap their cord too tightly or kink it, which causes signal interference. It also occurs with frequent use and wear and tear, which is normal.
Take good care of your cord, and it'll be there to last you a long time.
Im getting small electrical shocks through the docking connectors. Not enough to hurt, but sure enough to wake me up
Happens only when cable is connected.
Anyone else noticed this? Could it be erroneus circuits? If so I will return my device.
This has to be a joke...
also, why are you playing with the contacts?
i heard its best to stick paper clips in it

The docking connectors are on the side of the device; it's more unlikely that you WOULDN'T come in contact with them through normal handling.
Nope, plugged in and not getting shocked. See if you're grounded
Not me. Tried it while plugged in to AC power, even made my fingertip a bit moist for better conductivity: nothing.
If you're not joking I would definitely get a replacement unit.
Im definetely not joking.
First I thought my phone was vibrating, but I have been able to repeat it. Feels kinda like getting a spark from a disassembled lighter. Im not sure but it takes some time between each spark. Makes me think it might be static electricity built up somewhere, maybe from me and then discharged through the connectors?

Maybe. If it's static it will be gone after discharge, and would need to build up again before you would feel another shock.
This might be related.
I just plugged in my phone and I must've been touching the pogo pins, it said "starting navigation" or something like that, but didn't start any app.
This has actually happened to me on several occasions and only while plugged in. Did you return your phone? Figure out why it happens?
I had that experience too: I was shocked when I just found out that Im getting shocked by my Galaxy Nexus.
Touching the dock connectors while the device is plugged in delivers a decent, constant current flowing through my finger. Very well noticeable, and on the edge of being painful for me.
You need a humidifier in your home or room or cave or wherever you reside. The low voltage (5V) and low current shouldn't shock you.
Sitting on the Australian East Coast, we have 99% humidity right now.
Playing around and intentionally touching the connectors for a few times now provided me with some more serious shocks (getting close to the pain level of licking a 9V block).
Enough for me to cover the ports with some clear tape for now..
in the us, with my verizon gnex, i can read ~7-8 vac from pogo->ground with the stock usb cable & ac adapter. so you can get a tiny amount of potential, but there is no large current. unplugging the phone i realized the voltage is coming from the shield on the usb cable, so its the charger, and not the phone with the issue (if it even is one)
BUT, this is way better than the 35vac i can read on a similar style iphone charger (one new, one old)(& same gnex stock usb connector shield measurement)...needless to say i'm not using that charger again on my gnex
So if my phone is Dash charging, I sometimes get a tingling sensation if I touch the metal of the phone. Almost like a low level electric shock/pins and needles type feeling. If it starts to happen, I can make it stop by disconnecting the USB cable from the phone...
I know it sounds a bit crazy, but has anyone else experienced or noticed this?
No, not for me
No, definitely not. And to be honest, I think u should get a replacement!
I experience that too, even with normal chargers, and I measured 0.5V Ac from the phone Metal to the protective. Not sure why I measure Ac voltage because the phone charges with DC current.
If I get free time I will investigate it with an oscilloscope at the university.
No I haven't. I'd be concerned and would at least contact OnePlus.
I get the same feeling with my aluminium laptop. You see, most appliances with metal cases require grounding. It is done with the 3rd pin of your power connector (pin, hole, schucko on the sides, whatever). Phone chargers and many new laptop chargers don't have that. The designers decided that the static electricity problem would bother people less than having a big wall plug.
Plug your charger to the wall the other way (turn it 180 degrees), sometimes it helps (depends on charger design for your country).
Yup, the adapter needs to go in the right way.

Got the same sensation ! (happy to see other people with the same)
But not only during charging, when I handle it with one hand (and when it is set "screen against the ground" and that I touch it) I also feel this thing. Should I talk to OnePlus? Then replacement ?
Yeah ditto same. I thought it was the vibration motor being loose or being triggered unintentionally when charging.

Thats fue to a faulty ground connection on you home electric system. Happens on old houses or on poorly made wall sockets. Happened to me on other devices and was my wall socket missing ground connection.

Thanks everyone, it seems benign so I won't worry about it anymore. It's my first time with a metal uni body phone! I'm in the UK so the charger should be grounded by the three pin plug. The house is old so maybe the electrics aren't fantastic...
could be your power wiring. maybe some induction current. thats why im using an extension cord with a build in fuse / filter
Nope not from me

Do we need replacement? Or it is fine?
Yes. It has to do something with grounding I guess. I had the same issue. I posted it above. Tried reversing the pins and charging and the same. It doesn't have a third plug for grounding tho (Indian Norm). I was using a 3 Pin extension but still experiencing the same. Need to contact Oneplus now I guess? It doesn't effect when you have a rubber cover on. But I am afraid it will ruin my phone or something or what. Idk lol

Hi everyone,
A few days ago, this problem started to show on my device.
When I'm charging it, it says "charging", but even the slightest movement can stop the phone from charging.
Sometimes it even toggles *charging*/*not charging* without me moving it at all.
For example, if the battery is on <15%, the phone will vibrate - so when I charge it when it's below 15%, if I touch it, it vibrates every 5 seconds or so.
It's really terrible... I once left the phone to charge for a few hours just to come back and find out it wasn't charging.
I've tried different USB cables, power sockets, chargers, so I guess it has to be a problem with my device.
I'm pretty confident it's a hardware issue, and I bought it around 10 month ago, so warranty should still be up. However, I don't remember anything particular that could damage the charging port, and this started all of a sudden (a day earlier it was charging perfectly).
I'd like to hear some opinions, solutions, and if any of you have had this before.
Thanks,
Barak
It's definitely the charging port, maybe it was faulty from factory, send it in warranty
Get a dress making pin or something tough and really pointy and carefully scratch inside the port. Be careful of the plastic inside. Do not bend it or snap it off. Do not scratch or pick at the pins on the top of the plastic. Only scratch around the plastic.
Shine a torch in and see if you can find any loose debris that you may have dislodged. Keep doing it until you can't get no more fluff etc out of it and try plugging the charger in again.
It should have a nice solid clunk as the plug goes in and seats properly now.
Hey, thanks alot for your replies. @shivadow I've tried cleaning the port like you said , this maybe helped a little but the problem is not solved.
P.S : I noticed that there is a position which is problematic.
When the phone is connected to the charger, if I hold the cable with my hand, and push it upwards (I exert force on the cable in a direction vertical to the screen). This is when it stops charging. Just stating this if it might help you diagnosing something specific.
Anyway I think I'll be sending it back to the lab this week or next week, thanks a lot for your help!
Either a faulty cable, plug or socket. If it happens with other cables it'll be the socket. If you know for a fact that the plug is seating correctly but you still have the problem then either worn pins or worn socket.
So it turns out that when I tried to check whether the charger, or the USB cable is to blame, I tried 2 different cables, but they were both faulty, which made me think the problem is with my HTC.
Now I tried changing phones and still had the same issue, so I tried more usb cables, and voila! Works like a charm
Thanks for the help @shivadow, much appreciated.
Always blame the cable first!
