When I put my phone to the charger, the metal strip at the top is under power.
When I get a call and it's on the charger it's even worse and hurts my ear .
The same happens when I charge it by USB on my PC.
Is there anyone who has (had) the same problem or more important has a solution?
The phone has already been twice to repair but it's still not solved.

I have not experienced this problem. Please take it to your local HTC Centre or the shop where you bought you HD Mini, this is not normal behaviour. There are in fact a lot of defect units in HD Mini

In most modern power supplies/chargers there is a high value resistor and low value capacitor connected between the 'Mains' side of the unit and the output. This can sometimes cause this effect. If you run a sensitive part of the body (the back of the hand for example) along a metal cased item (such as a video recorder or hi-fi unit) you can sometimes feel it there too. I could be that your ear is sensitive enough to pick up this (very) slight voltage.
If you can feel it in your ear, but not in your fingers, it is most likely to be this small 'bleed' voltage and is normal. You could try a different make of charger (or as suggested above) a usb port from a computer and you might find that you are less sensitive to the values of resistor/capacitor fitted in these alternate power supplies.
The old style of power supply with a weighty transformer didn't need the 'bleed' resistor/capacitors and so you only noticed this effect when connecting an 'old' style item to a 'newer' one when you could sometimes see a small spark when the two were connected. Again you might sometimes see this effect when plugging an aerial lead into a TV or Video Recorder, for the same reasons.
Its very simple, your computer is not earthed correctly. I had the same problem with my last apartment, when I charged the phone thru my computer and touched the radiator with my foot the phone bite my ear.
The apartment had old sockets without earthing pins.
My phone has not breaked down due to this but I have problem with usb connection to my computer, it always find the phone as unknown device.
So if you pull a wire between you computer chassie and a radiator or sink this problem will disappear.

I'm starting to have real problems with my USB plug. At first it would drop charger plugs when it was on the wall, so I put it upside down. But now I can't connect to the PC all the time either. I have to jiggle the plug a bit or even breathe down in it (the moist makes the connection better). Has anybody else had that problem and fixed it in any way? I suppose the plug is soldered on in such a way that it has to go to a workshop, right?
i strongly suggest you to send it for repair or resolder the base of the connection(this is user servicable provided you have some soldering skills) so it doesnt wiggle. i'd probly even suggest to hotglue the plug but before you do so make sure the plug is sitted properly and it does sync
the same thing happened to me and with a bit of jiggle the plug broke off and now its permenently damaged(ie it will never sync via USB again) so far with self repair i only manage to make it charge
i got no idea how to reattach a 10pin mini USB plug to my board and some of the copper tracks looks damaged which means if i send it to the shops, its a $500 repair and a board swap
Q: Suddenly my car charger (cigarette lighter plugged) is not working anymore. After 5 mins. my device stops charging..... is there anybody having the same problem and knows how to solve it?
If it's after a period of time maybe a battery contact issue?

If you've already read the sticky posts relating to car chargers and your (mystery brand) charger isn't one of those, then maybe your phones battery terminals and connectors need careful cleaning with a cotton bud moistened with contact cleaner or IPA. I had a problem with my mains charger ceasing to charge my TyTN II after a minute or two a long time ago and after cleaning as described, the problem went away. Be sure not to spray the contact cleaner or IPA onto the phone or battery, only the cotton bud/Q-tip and then gently rub that on the spring contacts and battery terminals. How does charging via mains adapter or PC USB port go?

It still could be a battery contact issue as voltages may differ slightly when using the car charger compared to the other forms of charging. As an example if the Kaiser is set to stop charging when the supply voltage drops below a certain value and the car chargers voltage is lower to start with (and fluctuates with normal driving/electrical usage) then that may explain things. It's well worth doing this cleaning every so often anyway as a matter of course so give it a try and see what happens.
Additionally, could heat be a factor eg if it's sitting on a hot dash or near heater vents (the device is designed to not recharge above certain temperatures)?

Thanks for the advice, i will give it a try
if you have any adapters that allow for another usb input, nice a headphone adapter, or the HTC Multifunction Audio Cable YC A300, a ycable or anything with a USB in, try that first.
if that doesn't work, take the unit into your retailer and they will give you a new (or refurbed) unit, as your USB port may have a pin or two out of whack.
This may be weird, but my tilt used to charge just fine from most USB chargers(car, AC, usb cords). One fine day it quit charging off most chargers except the official AC charger from AT&T. I tried to fiddle with the USB pins inside as one looked like it might be a bit bent/damaged. No luck.
However, yesterday I noticed that My Settings->System->Power->Advanced settings page had following option checked:
'When device is turned on, do not charge the battery when connected to the PC'.
Once I unchecked it, it started charging of PC USB cables (obviously), but strangely enough also charging from my car charger(s). Hope this works out for you or someone else...

It is probably because your normal USB pin 4 and 5 in the cable of your other chargers are not shorted to signal that there is no data connection. So your phone thinks it is connected to a PC (or a device which might send it data), hence not charging the battery according to that setting
I have a similar infuriating problem, i have had a MDA VArio III for over a year now, had an issue with my last one and had a replacement issued in October. Now i have used the Brodit active holder (ciggy lighter version) since day one over a year ago and wit the new MDA as well. now all of a sudden phone will not charge in the holder, borrowed a friends active cradle still no charge, used a no brand usb ciggy ligther charger and charges fine!!!!
When phoe n is placed in the holder orange charging light comes on but phone does not charge and the light goes out 5 mins later!!!
any ideas anyone???
thanks
Matt

Problem solved - Pin 5 on my phone was ever so slightly out of alignment, bent back into place and all is now well! strange it only affected the brodit holders, nothing else!
Car charger failure explained
I also experienced this same problem and actually broke my phones mini usb plug in frustration at lack of charging. Got it fixed again though
The reason for this problem has become apparent since my phone was repaired. In your car, like my car when the heater is switched on it will gradually heat up the cigarette lighter socket. My charger cable like yours has a thermal safety circuit built into it. So when the ciggy socket heats up the heat is transferred to the charger plug and breaks the elec charging circuit. You might see me driving around London with my charger plug hanging out of my window (to cool it down) on a Winter's day!!! Honk if you do.
The solution would be a cheaper charger without the thermal circuit built in. Go into Maplins or PC World and ask them for that..... They dont know what your talking about, because I have already tried.......! Good luck
You just need to make sure to enable your phone to charge when connected to PC.

UN-CHECK the box that said "When device is turned on, DO NOT CHARGE the battery when connected to PC"
I noticed since last week that when i put to charge my HD2 with its AC power supply, there is a strange effect on the touch screen:
if it is charging on a table, and i touch only the display and drag, it feels as if the display has an invisible grid, or some kind of static charge, draging with my finger is strange. while if i hold it with my other hand this effect disappears. With USB charging this doesn't occur.
Is it normal? am i having a problem?
I got my HD2 a couple of weeks ago, and most of the time i charge with the usb cable connected to the computer, but once in a while i also need to charge with AC power supply.
Mayby your HD2 is possessed by the electric monster or something!
No, well try cleaning your Hd2's screen with a different cleaner. Note: I do actually know what you are talking about I fell it now. I think its farly normal and goes mostly unnoticed.

Yes, if it's charging alone or if i hold it with both hand i don't notice anything, but using it on the table, or holding it with two fingers by the rubber borders (leaving it ungrounded by my body) i will have this strange feeling, discharging some static though the touch display
Yeah bro. i feel it too at times
The cause could be you, your footwear (socks, and/or shoes), the carpet causing a static build up or just simply a voltage difference between the table and the power supply earthing.
The power supply unit will have an isolated charge, where as the computer will have a grounded connection.
As long as you don't get a shock or the phone doesn't get an electrical discharge, then I wouldn't bother about it.
Run your finger tip across the battery cover when on ac, same feeling but bigger
This is caused by the charger current leak to ground. Since the charger isn't grounded, this leak current goes through your body when you touch any conductive parts on your HD2, or even it's screen.
This current leak should be limited by safety standards, and should do no harm neither to you nor the device, but, you know, faulty chargers happen, so if you touch the thing and it causes you to take you hand off with an uncontrollable "OUCH " cry, don't think twice before replacing that charger
Note that the "effect" is going to be much stronger if you are touching a grounded surface with your naked skin, for example, standing on a wet floor barefoot, or holding a water pipe with another hand. The "wet" part gives it so much more conductance, it actually becomes a lot more dangerous when the equipment is faulty. This is one of the reasons why it is usually recommended to never operate anything electrical when you are wet.

not really...
it's just a faulty (not grounded) charger - having the same issue with mine although not on the screen but touching the back cover is really unconfortable.
have anyone got issues with S2 when plugged into power?
ie when I start recharging direct from 240V adapter, my S2 started getting VERY laggy and slow.
It immediately goes back to normal response when I unplug power.
I have never problem like you

Try using an alternative charger...probably your mains charger or the usb connector on the charger is damaged.
I'm pretty sure its a issue with the s/w as I have used the charger on another phone without any issue.
unless its one of the apps I'm using, not sure how to narrow it down.
mtrax...
I have the same issue.
You´re not alone...LOL
FYI the common issue I have when plugged in is that its not easy to unlock screen, takes me a 2-3 swipes to unlock screen and after that it seems that it ignores every other key press..
Any one reported this to Samsung? I will try to log a ticket to see what happens.
Try do a multi touch test while its plugged in see if the screens acting funny.
how do I do a multi-touch test?
what will that prove? as the screen works fine when unplugged.
I have the same issue but only when charging with the usb lead (with usb power adapter) instead of the standard mains charger. Think it might have stopped now that debugging is enabled and the Samsung kies screen doesn't come up when i connect the usb.
Sent from my GT-I9100 using XDA App
Took my phone 2 hours to charge from 36 % to 100 %
note this issue doesn't occur when charging via PC ONLY via 240V mains, but let me try with USB debugging on.
edit tried USB debbuging still has issue.
Note is the 240V USB cable different from a normal USB cable? ie perhaps the device thinks its a PC connection
the phone is laggy because of the electrical interference from a faulty charger or some other electrical equipment in the near vicinity...
Please note that actually the capacitive touchscreen becomes laggy not the applications/services...
keep it away from the electrical interference...use the samsung original charger..gud quality USB cable....and the issue will be gone... for sure
looks like its the charger, the A/C adapter I got with the phone was UK which is why I didn't use it to begin with, but tried the samsung one with a UK/AU adapter and its fine..
hmm who would have thought that was the issue...
interesting it didn't affect my other HTC phone.
Same issue here, but something special:
I ebayed another charger for my sgs2, original samsung one. Same serial number, same description, same style.. but i got the charging problem only with the new one.
With my original charger (the one, which was delivered with the phone) works fine. No slow and no lag.
The new one was about 5 euro, seems to be an original...
to demonstrate my point that its the electrical interference from the dodgy chargers onto the capacitive touchscreen... do this and report back...
plug the faulty charger onto the socket BUT DO NOT charge the phone with it...
keep the phone near to the charger wires etc....(not in charge)... you will see the screen lagging sometimes unresponsive...
now move the phone away ...it will work fine..
you can keep on using the dodgy chargers for charging...but use the phone only after it has been charged and is away from the charger...

I am not able to reproduce that with my original charger. There is no lag or any other problem. Switching to my second "original" (ebay 5 €uro) samsung charger leads me direct to the lag and your description. First i thought my second one is not an original one, but because of your description there seems to be a diffrent quality on the original charger depending on it production date.. unit.. charge.. or whatever.
I bought a sgs2 from the UK, and have a UK to AUS converter on the stock charger and I have no lag when it's charging or near chargers.
Sorry. Not a problem here. Writing now and plugged. Very responsive.

The electrical interference with the capacitive display is bullcrap since it needs electrical properties to respond. So it depends on whether your body has enough electrical properties.
So back to the point:
It is due to CPU reducing the clock speeds to prevent the phone from overheating as the battery itself produces enough heat anyway.
Many other people may not notice it since they may not perform intensive tasks while the phone is plugged in and the variation itself is also almost unnoticeable.
I have the same issue but as I said, it's almost unnoticeable to even bring it up in this forum. I haven't done any testing myself to prove this, but the same safety feature is implemented in most modern phones.
I have the same issue - I also had this issue with my Atrix.
Occasionally since I got the phoone I've noticed that the audiobooks I've listened to have suddenly stopped, and prompting me to press play again; it always seemed to happen when I had a hand in my pocket, so I probably just assumed I had touched the screen or something. It was annoying, but I just continued on.
Then late last week after it happened while I was at my desktop and just moving the phone, I investigated a bit more closely.
I found that I could wiggled the headphone USB dongle, and the fit was not as solid as you'd expect (of course, I hadn't really checked this earlier, just putting in and taking out USB connectors up to this point). As I wiggled it, the audio would stop as if my headphones were disconnected and reconnected. Which must've been what had happened before.
Then I checked with my charging cord. Same kind of fit, I could wiggle the connector a few degrees. Enough for me to raise some concern about it being a faulty USB port, or it having somehow gotten loose in the shell.
This is probably RMA worthy, I'm guessing. The question is what will OP do? Replace the whole phone? Repair it (repair what exactly, I'm wondering)? I've not dealt with their support before, and I couldn't really find any suitable thing under their repair service categories.
Could some people check how snug their USB connector fit is and report back to me, so I could find out if this isn't how it's supposed to be?
First check your USB port for lint. I typically use a needle to clean mine out (Don't short any of the pins if using a metal needle). Lint will prevent the cable from fully seating and cause it to feel loose.

The USB port is totally clean. Couldn't even spot any dust particles under a bright light.
I know the 3.5mm headphone jack isn't technically rated for as many cycles as a USB C connector but I still feel it held up to abuse like being in a pocket better than any type of USB connector.
