Loose USB power connector

I've noticed after a couple of weeks of use (= quite a lot of charging) that he usb connector as become quite loose. I have to position the cable carefully and then not move the device while charging or the orange charge light goes out and it stops.
I can see this being more of a prob in a car mount than on my desk but it's a pain. Wondering whether this will come under the warranty.

Ofcourse it will. Unless they can prove its user error and/or bad handling. This depends on law per country or in eu.

Charging stripes: And removing the charging stripes, well. I don't see any problem there. I know other people who have the micro usb connecter for a long time and are using a cradle, car charger and other stuff a lot (not desire, different device). But no problems at all with the micro-usb connector. Never had any problems with the mini-usb connector as well. Don't see why it would suddenly be a problem now.
It feels quite solid, think it works great on my desktop cradle as well.

oh really? You don't see a problem here? LOL

Mines wobbled since the start, luckily it hasn't come loose whilst charging, hopefully it won't or its going straight back.

Exact same observation here and it's only become an issue in the past 3 days for me after more than 2 months in use. If I don't keep it still and without even the slightest forces pushing/pulling either side, the USB connection drops.

Yeah - it was fine and now it's wobbly and fussy. Experience suggests that this is the start of a slow decline that ends up with selotape.

Having a cradle and carkit with connector myself, and using it for quite some time: no, I don't see a problem.
I never had any problems with charging connectors, ever.
But you get my credits for remembering this, kudos.
As I am currently importing micro usb adapters, cradle and cables I do see quite some differences.
Micro usb connectors from some suppliers are more loose than others. The original is still rock solid here, even after some weeks of use.
The same with different cradles I've tried. Some fit perfectly while others hold the phone in place only with the micro usb. So the weight is all on the connector which means its a bad cradle.
Sure, charging stripes can solve the problem of a bad cradle, but so does a decently made cradle which is actually made for the Desire and supports it properly.

[TROUBLE] Getting electrical shocks from docking contacts

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

Qi wireless charger

Hi,
I recently bought a qi wireless charger because my charger port of the phone broke and it's too expensive to fix.
Anyways, yesterday I left it for 2 hours the % went from 49 to 90 which I was quite happy with but I let it charge over night and it only went from 34% to 50%.
I am rooted and on AOSP.
I check the wireless current and sometimes as soon as I put it on the pad it's 1000ma but then it keeps dropping quick to 100ma. The pad as an output of 1000ma.
Csn someone tell me how to fix the slow charge. Thanks

you're probalby not lining it up properly. that happens when you've misaligned the pad to the charger. find the sweet spot and just remember to place your phone there the same way.
if you're handy,you can probably also come up with a cradle of some sort so the phone falls right in place everytime.

I placed mini rare earth magnets under the phone's back plate, just 2 on the top area, and then 2 on the Qi wireless charger so the phone aligns perfectly with the charger, and gets the best charge it can get.. Also I opened up all my Qi Chargers and used my Dremel to remove all the extra plastic, as much as I could to remove any kind of resistance or space between the Tx Coil and the Rx Coil.. I tested the best place they could be aligned with a Multi Meter, and then added magnets.. Works like a charm.. Its a pain in the ass, but mine works out pretty well. I didn't place the magnets on the inside, I placed them on the outside of the charger.. Works well

thats what I purchased..

uh wow... that's seriously overkill but sure.. you can do that..
although i wonder if putting magnets that strong in your phone will mess with your gps and magnetometer.
i would say a small plastic cradle or creating little edges on the transmitter so the phone just physically falls in would be an easier and safer alternative that using a dremel on your receiver.

I would of thought the same thing, but it has given me zero problems when the magnets are set up top.. HOWEVER, when I tried to place 2 near the bottom, it caused all kinds of problems with USB charging and my phone locked up a few times... I'm glad the damage wasn't permanent.. I used my Hotglue gun to hold them into place, the magnetic field caused a short in the Gluegun and it EXPLODED in my hand.. I was lucky enough to drop it right when I heard the sizzle and BANG.. So when playing with strong magnets.. Be careful.
Edit: I also have an external case with the same type magnets, and even with the case on, it doesn't give me any issues, at least any I'm aware of.. I made a magnetic mount on my desktop pc, just for kicks.. But since the case is metal, I can't put a Qi charging coil on it.. Now that would be neat..

yeah.. that's dangerous in general. I honestly would not recommend anyone to do what you did considering you almost ended up with stuff blowing up un your hands.

The idea behind Qi is simple: all devices with the Qi logo will work with all Qi chargers. That’s it. No need for separate chargers, no need for cables, and no need for adapters when traveling. Qi is a global standard – this means that your device can be charged wirelessly wherever you are.

Sparks when connecting charger

today i noticed some sparks while trying to get the charger in place. is this something to worry about? What is the best way to get the charger in place?
Sent from my SM-T320 using Tapatalk

That doesn't sound right. May want to consider a warranty replacement...

Unless you were purposefully keeping the watch from making a connection sounds like a bad charger

I did it in a dark room just to see...no sparks. Low voltages rarely spark.

This is easily achieved if you miss the charging pads on the watch and the pins on the charging puck hit the stainless portion of the back case.
It's a relatively low voltage short though, and I'm assuming they've built protection into the charger itself if it's left this way for extended periods.

Question Unusual sensation when phone is charging

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.
