Electric Charges while charging

Hi,
Any of you feel that there is electric charges on ur ear while charging when making a call? when i disconnect the cable it is okay. only on the receiver portion. could it be a faulty battery?

I've not experienced that issue, but then again I've not tried using the phone during charging.
Are you charging from the mains charger, or from a PC?
It is most probably a small amount of electricity "leaking through" down the cable from whatever you are charging it from.
This might sound a bit scary, but is not necessarily a danger or even a fault. PC power supplies in particular have components to stop EMC (radio interference) that can sometimes cause a bit of this "electrical leakage".
If you are using the supplied charger, make sure it is not damp or wet, as this really could be a danger.

Hi,
I am refering to the charger. using PC is okay. i tried with different power point still the same. no it is dry. shld i go to the service center

I just tested the electrical mains leakage current from my own charger.
It's around 15 microamps, probably not enough for most people to feel but maybe on a sensitive part like the ear it's possible. I think that the CE requirement is 250 microamps maximum so it meets statutory requirements.
Obviously I cannot tell whether there is a fault in your charger, but if it was mine and the current was not actually uncomfortable, I wouldn't worry too much about it. I would expect genuine HTC chargers to be 100% safety tested.

i did notice the same from mine while using the wall charger.. on my hand tho not my ear.. more than once.. kind of weird.. but w/e haha

Yes, I have had 4 HTC phones for myself and every of them has done it while on wallcharger. It is kinda annoying when speaking on the phone.
Wizard did it really much and couldnt sometimes talk on the phone same time.
2 Diamonds did it, one i use now has invisible shield so it kinda stays in them because of rubber
HD does that but not much or not at all.
Maybe it is because of aluminium or metal casing on phone like wizard and Diamond, havent yet tested HD much. Got it yesterday :>

Hi,
so it a norm for all HTC device? so it is not faulty?
thankx

Screen acting up when plugged in

Whenever my Evo is charging, the touchscreen acts funny. The bottom buttons don't light up, the screen sensitivity is all over the place, and it's actually picked up calls on its own. It's crazy. Anyone else having this problem?

Mine does act a little off, but not as bad as what you describe. The only consistent problem it has is that keyboard long touch doesn't work when charging. But it's no big deal since I only charge it when im sleeping now.

I have the same issue. Last night, while I had my phone plugged in and fully charged, I noticed that the buttons at the bottom were not lighting up. Initially I thought they went bad, but a reboot turned them on for a few seconds.
After playing around with it for awhile, it has to do with the light sensor I think. I'm wondering if the solid green LED (when it's fully charged) is just bright enough to where the light sensor right under it detects the light and doesn't turn on the soft button lights.

I had the same issue when using a particular aftermarket charger. Never have that issue when using the stock charger.

I'm using the stock charger and I have the problems he described.
I found that I can get the button lights to come on for a few seconds when it's plugged in if I cover the light sensor.

Odd, mine does it on the stock one. I'll have to check an aftermarket one and see if there's a difference.

One more here. After the OTA my touch input is all wonky when I'm plugged in.

I have the same problem with both the aftermarket and stock chargers.but when I use my old LG charger there is no problem.(this is my 3rd evo due to cracked camera lenses, they have all had the same issue).

Those with this problem. Are you on the newest OTA?
Any custom rom I run based off the latest ota my touch screen gets crazy and I don't have to have it plugged in..
As soon as I load any other custom rom that is not based off the latest ota it never happens..
I think whatever they did is the problem..I wonder if this stems from the fact that the screens aren't even the same in each EVO.

Ditto. ShapeWriter goes bonkers. Not every time it's plugged in, though. Makes it impossible to use ShapeWriter. Unplug it, works fine again.

I am on the latest OTA but this has been a problem since day one, I've been through every update.

Doesn't matter for me which charger I'm using. I exchanged mine for another one. The new one works except the long press on the keyboard... and only intermittently. Extremely weird. Both were 003's with Novatek screens.

I have this same problem. Its near impossible to use swype...the line shoots all over the place when im trying to type.
Im using DamageControl

Are you hitting them with a hammer? I don't get how people can go through phones like this....really?

update
I have noticed that it's only wonky in portrait mode. If I go to the landscape mode, everythings fine.

What are you people smokin' ..j/k I have the wall charger that came with my EVO and the wall charger that came with my Touch Pro and I don't have any problem at all. Are any of you plugged into a surge protector? They can cause unusual problems and behaviors with PED's

I had the same problem using an aftermarket charger, but not with the stock charger. The stock charger says it outputs 5.2 volts while the stock charger says it outputs 5 volts... would that cause any problems?

I had this same problem with a cheap walmart charger. Then one day with the stock charger. I move my chargers frequently but realized that I always plug it in the socket the same way.
Long story short, flip the charger. Solved my problems. I guess its a polarity problem or something. It charges with the chargers plugged in whatever way, but the screen messes up one way and not the other.

I had that problem with one evo but not another

Using the stock charger and whilst it's plugged in, the screen is completely un-usable. However, my touch screen has been acting slow and weird at times the past 2/3 weeks. ;( I think everything on this phone is just ****ty.

Oh no. Screen calibration issue.

So my main complaint about the nexus 1 was the crazy digitizer. I am sitting here playing pocket legends and all of a sudden my screen starts going crazy just like on the nexus 1. I ran screen test toolkit and on the trace test i got sharp vertical lines that shot out from where my finger was tracing. I did have the phone plugged in at the time and since unplugging it seems to have gone away but the is reason enough to concern. Anyone else had this issue? May just take my phone back and get a replacement just in case.
Update: as much as I feel like a bonehead for admitting this I found the culprit. Apparently the charger i was using is not playing nice with the nexus s. It is the same charger i use for my nexus 1 an apparently it has a different power output that the nexus s doesn't like very much. Hope my mistake will help others.

I tried charging over USB at a friend's house on his dinosaur iMac, the screen started acting completely screwy as well.

this is really an intresting behavior. i didnt know a scren could do such a thing in different charger.. . live and learn

yea, why does this do this? I wonder can it be fixed with software

Why would you even try to charge it with something else since a wall charger came with it.

Because you can charge an Android phone via USB cable?
That's I think an official feature of Android.
And it MUST WORK WELL!
If not, then it is a bug in the software or hardware
I read a lot about this reports, anyone post into Google official forum?

i think you need to check other phones. as far as i know charging from usb less amp than the wall. so it shouldnt show any weird calibration issues or flicker. double check man

Yes, max amp from USB is 0.5A. Typical output for smartphone chargers is 1A. But this shouldnt be a problem, and also less amp means longer batterylife on the long run cause it doesnt stresses battery as much.

I think it's because the touchscreen on the NS seems to be more sensitive than most phones (I can get it to register input without even touching the screen sometimes) that it gets disrupted by other sources of electrical conductivity... such as the charger. Mine is ok, never really tried with the charger plugged in though. I ran multitouch visible test and I was satisfied with the tracking, it's the same if not better than the Vibrant's, which can handle 5 simultaneous inputs.

can plug and unplug charger repeatedly cause harm?

so I found my little sister plugging and unpluging the charger repeatedly, well she's a child I can't blame she was playing,but I can blame my stupidity for leaving my phone with her,luckily the charger wasn't connected to the wall so there was no electricity,anyway the phone charges and everything, but I can see 2 aligned marks on the rubber that covers the port,so what else might have happened? bent port?? is the port inside the phone bendable or tough?

Makes me cringe thinking about it ? if everything is still working though it's probably fine but only time will tell if the port fails. If you use wireless charger that will cut down the amount of times you have to plug it in. Before wireless charging I would use charger and ota daily on my Samsung devices and never had a port fail.

thank you, well after this accident I will definitely get a wireless charger, but I have a question what do mean by 'time will tell if the port fails' I mean if it got damaged the phone wouldn't charge at all right? another question if any thing bad happened to the port would there be any possibility that It still charges however affect battery life cause it to drain fast for an example?

Just saying port couldve got minimal damage and a problem could arise downdown the road. Ex something bent that event breaks after multiple uses. I highly doubt this will happen just an example. All newer phones have safeguards overcharging, undervolting, etc so all you internals are fine especially with the charger being unplugged from the wall. Don't over think it if the phone starts acting up find an excuse to get a warranty replacement

OK I got it, unfortunately I can't get a replacement as the 14 days are over but I hope that no harm was done, thank you.

Charging while using gmaps?

So because the V20 doesn't fast charge when the screen is on, does this make the phone useless when navigating on long trips as the charge won't be enough to counter the drain that gmaps requires?
If so, is there a way around this? I'm using an H918.

I just recently drove a trip that was a Lil over a thousand miles each way, took me about 20 hours there then 3 days later 20 hours back. I used the v20 for navigation the whole way there and back. The way there I had charged the phone fully before I left., but had the screen at roughly 85 percent brightness. The phone stayed charged fully the whole way. On the way back I didn't have a chance to charge the phone before I left and was actually worried that if the charger didn't charge it enough in the truck then it might go dead with the use of navigation and ask the sensors and everything it uses for navigation. My fears were needless, it charged slowly but charged..
Now I know this may not be the technical answer you hoped for but from my experience I would say you shouldn't have a problem navigating with screen on as long as your charging...now it was very hot the whole time with screen on and charging for 20hours. Hope this helps

I agree, my experience has been the same. The phone charges "slowly" while using Navigation, podcasting, etc.

Thanks for the great and informative answer. Doesn't sound like a problem at all then.

The v20 does fast charge. First make sure you actually have a good fast charger. Second, make sure that the cable you are using is a high quality usb cable. The usb cable can make all of the difference. Don't use the cheap cables that come with the chargers. I use the old oem cables that came with my pixel and they are outstanding.
Or look for usb 3.1 certified cables.
The phone does heat up when its fast charging so i usually re-direct one of the car vents towards the phone.

I picked up some Anker powerline+ cables so we'll see how those perform.

I forgot exactly where and my phone is not in front of me. I think it was the settings pull down from the top. When its fast charging you should see it say fast charging on that screen.
I went though at least a dozen chargers until i figured out it was the cable limiting the current to the phone. Also the longer the cable, the higher the resistance. So generally speaking the thicker the cable, the better it will work.

I think the V20 only goes into fast charge when the screen is off.

That is not my experience.
When the phone is connected to a fast charger, the pull down from notifications should show a notification:
Android System
Fast charging Percentage
Conntected to a fast charger
even when the screen is on. Let me know if you need a screenshot.

Correct and if you have an inline usb meter like i do then you will see it gets to 12W with screen off and around 5W with screen on.
The way you tell if fast charging is working is you will see a circle around the thunderbolt up on the status bar. This means the fast charge protocol has successfully negotiated and will commence when the screen turns off. Should display within a few seconds of plugging in.
Make sure the cable is properly seated in the phone and on the charging end. I usually charge from a power bank and sometimes that usb A end doesn't go in completely into the port on the power bank. Phone promptly mentions slow charging.

For a long while i used the charging cable that came with my G4 because that was a 20/28 20 meaning thicker for power than the anker powerline cable which is only 24/28. Anker doesn't make any 20/28 ones. Doesn't matter how fancy the braiding is.
I then went back to the stock ribbon cable. I tried with 6 inch cables and you know what. No discernable difference in charging speeds when it comes to the low power of a phone.
I say low because relative to a power bank it is. Mine takes up to 21W to quick charge and here a shorter thicker cable makes a difference. Though using the stock ribbon cables provided by the power bank again yielded similar acceptable results.
