Hi all,
I put my desire onto charge and as I picked it up and touched the outer casing I could feel this electric charge vibration on my skin, you can clearly feel it as you run your finger along the side of the metal part of the case.
What I want to know is.. Is this normal for this kind of phone or I have a dodgy one where something is touching something it's not supposed to be?
I had a laptop once that did the same, It had a metal lid.. A portege 3110 years ago and I assumed it was faulty.
I have the same thing, more so on the left side. Thought maybe everyone had it, be weird if they dont
It's perfectly normal. I would have thought that having a laptop that does the same would have confirmed that.

Yeh I have the same, it's perfectly fine
Even my iPod Classic does the same, had it for 3 years and it's still going strong.
But yeh I wouldn't worry about it, tbh I get turned on from the electric charge from my BEAST
I am super sensitive to things like this, It actualy makes it difficult for me to use the device while plugged into the charger. I stuck my multi meter on it to check and I get a high reading from the outer part of the case that surrounds the screen, even with the phone off charge and just sitting on the table I can get a decent reading.. Is there a design fault with this phone that's causing it to leak charge into the case?
I've checked my old N95, O2 Zest & Moto Droid for the same issue, I thought the droid would be the same since it has metal casing too but it's not.
Are you 100% sure this is normal? And what are the side effects of being continualy pumped with current while using your phone plugged in?
no, you should not be getting charge in the case....it does sound to me like you have a problem.
Mine has no such feeling when charging.
I can't imagine there's any dodgy side effects, it's only 5v at 1A. that's less than sticking a 9v battery on your tongue, but it's still not right i don;t think.
If you do send it back to HTC, get someone to take a picture of you and the multi-meter clearly showing the charge on the case. it's just an extra bit of evidence in your favour.
I don't have any such problems.

For those of you that can not feel this, try the following.
When the device is being charged, very lightly run your finger along the "metel" edge part of the screen.
Its the same effect that i have when in bed with an electric blanket on and i lightly touch the brick wall!
On another note, there is no "tingle" when charging from from a pc.
Same problem here.
When i charge it on my Acer laptop with Windows or Linux, everything is ok. Today i connected it to my EEEPC with Linux on it, and after the battery was approx. 90% charged again, it started to "wobble" when you touched it. Maybe it was there before, dunno ...
I can feel it on the screen and on the bezel. If i hold the phone with 2 hands, i can't feel it. And yes, i'm very sensitive to electrical currents
I don't think it's "fine" ...
I have the same problem, just assumed it was a faulty charger as my sisters charger, and my car charger don't replicate it.

Am I imagining it or is my Desire giving me mini electric shocks?
It's just like a tingling sensation from around the edge of the phone. **Edit Anyone know what sort of multimeter I would need to test this and what settings I would use**
Should I take my phone back - I only got it last week?
Also the phone seems to heat up towards the lower quarter of the back under use - is this also normal?
Thanks

Electric shocks are not normal, warming up is.

I know what you mean by the electric shocks. A buddy of mine had the exact same problem with his desire. He walked around for a week getting zapped as he wasn't sure if he was imagining it. Take it back to HTC. Your phone needs to be serviced.
does this only happen if the phone is connected via the USB port to some external device like a notebook or your AC adapter? Then it's normal.
Does this also happen if it's not connected to anything? Then it's not normal
Heat:
Yes, it's normal. The CPU with a small heat spreader is located at the bottom of the desire. And the CPU produces heat. The Desire can get really warm, so nothing to worry about.
This happens when it's not plugged into anything.
Thought I was going nuts but I don't think so - well no more than usual.
Anyone have any suggestions for testing this. I have a multimeter but have no idea what I should do with it! :-(
put your Desire on a wooden desk and touch it with only one finger on the bronze colored edge. Do you get a shock then?
Or do you only get a shock while holding it in your hand? Maybe because there's a high voltage between the edge and the USB connector?
set your multimeter to Voltage. Put one probe on the edge of the Desire (without touching the Desire with your finger or anything else), the other probe to the ground, e.g. a conductive heater or a blank heating pipe or the ground pole in your wall socket (but be careful ).
Measure both DC and AC voltages. Any high voltages? Something above a few mV?
Also measure the voltage between the casing and the USB socket frame.
My theory... metal casing + static charge = electric schock! Used to get these in clothes stores

I can't get any reading of my multimeter but I must admit to not really knowing what I'm doing!
"Static" .....hmmm I wonder!
Well, it's gone to be examined! They may even send it to HTC to be tested!
Lady in the shop gave me that knowing "you're a looney" look!
When I mentioned it was more like a tingle than a shock she smiled and said "Maybe that's why they call it a 'Desire' "! Should have seen that one coming!
Maybe it is just me and static but as I haven't had it on any of my previous HTC phones there must be something with the design that amplifies it!
Just have to wait and see...

Have my phone back from Vodafone:
"They are pleased to say the fault has been fixed"
"One of our engineers has thoroughly tested your phone. The repair centre was unable to identify a fault with your phone.
"As part of the repair process we have given your phone a full internal service including upgrading the software as this is how many faults are fixed!
So - the fault that they couldn't find is now fixed and my phone has new spark plugs and fresh oil!
Don't you just love automated letters!
So it's looking like it must be a static issue! Guess I'll just have to live with it!

When you look into the Note 7 recall and all of the information we have available, you have news outlets taking a biased point of view on the units. They have put words into both Samsung and the CPSC's mouth saying that the recalls are MANDATORY, that the Note 7 production has been permanently halted, and that the issue is the battery itself. In the meantime, Samsung themselves have announced that they CANNOT replicate the issue themselves, and the changing out of the battery would generally suggest that it was not the battery causing the problem. Plus, due to media coverage the issue has been severely exaggerated. According to the CPSC, only 96 units out of 1.9 million units sold in the US have been reported as overheating. In the two months since the release of the phone that is a 0.005% failure rate. That means the phone has a 99.995% chance of being perfectly fine. In terms of normal production, that would be considered a success by most companies. Samsung also has not announced anywhere on their site that production has been halted permenantly. They've said temporarily while they investigate. The investigation is NOT COMPLETE.
Now, if you take the battery out of the equation as the primary point of failure, there are three other points of possible failure that would be the most common cause to make the battery ignite. Those are software tampering, hardware tampering/error and the USB-C port/accessories.
Software: a partially flashed firmware could easily damage the charge rate systems to cause damage to the battery itself or damage the battery's protection board to the point where it can cause problems.
Hardware Tampering/Error: How many idiots have you seen on youtube sinking their Note7s to the bottom of a lake/river/pier, or drop testing them from heights that they are not rated for. Then count the # of people who replicate what other people do on youtube.. (Ghost pepper challenges anyone?)
USB-C Port/Accessories: USB-C has been under some controversy itself lately. Cheap USB cables have been sold that when used on devices damage not only the USB-C port, but also the power systems due to the cables being improperly wired. As well, the Note7 comes with USB-C accessories, one of which is a USB-A to a USB-C port adapter. This is used to use the unit AS a backup battery, or to attach flash drives to the unit and NOT to charge the unit. Many people have USB-A to USB-A cables. Imagine if someone used one of the faulty USB-C cables to charge the unit, or tried to use that adapter with a USB-A to USB-A cable to charge the unit. With only 96 cases reported of overheating, it's well within the number of people who don't understand technology enough to get the proper cables and/or use the unit up to spec. If the cable is not CERTIFIED by the USB-IF it could very well be a bad cable and have caused the issue.
What I'm saying here is look at the proof, look at the history of the devices you're attaching to the phone, look at human behavior, look at what the media's doing. We have people in this world who actually think TRUMP would make a good president. We have people in this world who snort condoms up their noses. It makes it completely possible that all 96 reported cases are 96 cases of users doing the wrong thing with their phones. It is very likely that out of 1.9 Million units sold in the US (according to CPSC), 96 of the people who bought Note 7s are simply idiots. (Plus there's a video of an idiot supposedly holding a Note 7 while the phone is catching fire. When a LI-Ion Battery overheats you can't hold it. not in your hands without receiving severe burns. Information below attached so you can see it all directly from the sources for the information on the Note 7 instead of from media locations.
Also, don't forget, some of these people with the phones who have overheated REFUSE to return them to Samsung for investigation. There is only one reason to refuse to turn in a destroyed device. If you tampered with it yourself.

Update: Just spoke with a supervisor at Verizon, and they are AWARE that this is a blown out of proportion recall and issue. As of the current moment, they are supporting the phone INDEFINITELY, until Samsung verifies what the problem is and completes the investigation. Then depending on the investigation result, they will decide what to do. I encourage people to call their carriers and talk to supervisors who have more information.
I ansolutely agree with you, around 100 devices in 2 million +, is better than many other quality standards around, and as you pointed out, many people handle devices in very bad ways
Well said. This is why I'm not getting rid of mine. BTW, you accidently put billion instead of million the first time.

Maybe the whole thing is a conspiracy by another company like LG or Apple. Paying people to do this to their phones then paying the media to overhype and overexaterate the whole thing. I don't think it's a coincidence this happened to the best phone Samsung has ever made. Let me rephrase that, the best phone ever created.
Think about this, how rediculous would it be if samsung found out it was an uncertified cable causing the entire problem, and that they took a multi-billion dollar loss over the cable. This is why all of this crap should not be happening until the investigation concludes.

Update with information from Verizon in first post.
NOW we're talking! Finally my kinda people! Where have you been the past couple of days? Now the dust is settling and the initial "shock" has subsided people are starting to think with clarity. Excuse the pun, but 'Think Different'
Keep it going, I LIKE this!! I was getting so lonely here getting called a conspiracy nut and such. Thank you my people!
I agree. My phone is perfect and I would keep it except I would like to receive updates and such. At&t told me it has a one year warranty. That I don't have to turn it in. I'm struggling real hard with this. I love this damn phone and nothing else compared to it. I think it's just another case of reefer madness.
My theory is that the playdoh like battery is just in a foil like cover, so it's easily squished. They have mentioned possible assembly problems with squishing it inside the phone being the cause, but I wonder if perhaps a high G drop on a floor might distort it sufficiently that, after a number of charge/discharge cycles, may develop those crystals which will fuse internally between squashed plates causing the battery run away we have all seen.
I doubt it is external to the battery as surely between battery and main phone assembly there will be short circuit protection (generally the metallic canister style batteries have this built in, but with a sealed phone and soft battery, this protection is probably the very first thing the phone battery cable plugs into).
I only dropped my N4 twice, my N7 never (ok, it hit ground inside a Gear VR when my son was being silly), but I have seen others who are far less careful with phones that may have dropped and distorted the battery putty enough to be more prone to internally fusing.
Although at least 2 photos show the phone in (melted) protector cases which should reduce the shock loading, perhaps these ones had the extra squished assembly with the SDI batteries which already had less internal tolerances than the Chinese one?

Another funny development that was brought up in another thread... The only video of the unit catching fire is a surveillance video from above... where you cannot actually see what device is spewing the smoke. The only reason its believed to be a note 7 is because someone SAID it is.
Thread cleaned.
Be respectful at all times.
Keep off topic disagreements to Private Message.

The problem is obviously not the charger. I've charged it many times from below 10% all the way to 100 on the samsung unit, and it has never caused a problem. My best guess is that it wont fail because I am using a certified cable.
Perhaps samsung should go the apple route and put a chip in their chargers so only certified chargers work.
With the invention of fast charging technology it is pretty risky to use cheapies.

just curious can note 7 avoid this catastrophe if the battery was removeable ,what are your views ?
Since we don't know what the cause was, my opinion is I don't know (well, I read something I haven't seen anywhere on the boards or any other news source but one but I won't state it because I have been accused of reading the news, it is in a language most won't understand anyway). But I am confident they should be able to fix the issue. I would largely prefer them to keep the IP68 rating.
You asked for some views so here are mine, much to the chagrin of many I'm sure but that's ok, that's just fine, really.
Based on currently available information which includes how Li-Ion batteries actually work, I personally would say the actual reason(s) that the Note 7 devices are considered to be defective is not because of the battery itself. So, while having a removable battery is a great thing - and I prefer devices that have removable batteries personally and only buy such devices with my own cash (I got my GS7A as a trade for a laptop so it didn't cost me any cash out of pocket).
Try this hypothetical situation for just a moment, if you will.
Without naming name brands or particular models, say you have a smartphone that has a removable back cover and a removable battery inside. To get to that battery and remove it you must handle the device well enough to be able to get at the back cover, probably find the tiny little gap that most have so you can insert a fingernail into it or perhaps a nail file, a butter knife, anything at all that can fit in that little gap so you can then start to lift the back cover off the device, unsnapping the retainer clips as you do so.
Follow me so far?
After the back cover is fully removed from the device you then have to remove the actual battery itself. Most removable batteries have a spot where you can "hook" a fingernail into and then pull gently to pry the battery up and out of the frame of the phone itself. If necessary you can probably turn the smartphone display side up and then smack the phone into your palm and the battery would probably drop out into hand, but generally most people just use their fingernail or perhaps a spudger to pry the battery loose from the device.
Voila, you've removed the battery entirely, congratulations.
Now here's where it gets interesting:
Say this smartphone has a defect that is occurring at random times on some devices - some of them will exhibit the defect (as cause and effect) and some devices may never exhibit it because of the random nature of how it presents itself. Considering this random nature of the defect presenting itself, say that at some point either while you are actually using your smartphone in your hand, or it's in your pocket, or it's mounted to your dash in your car with a holder, or it's sitting on a desk or table, or anywhere at all really and...
It starts smoking.
I mean it literally starts smoking and the smoke is quiet visible and you can see it easily. You can even smell it as it's happening. If the phone is in your hand when it starts smoking your most common reaction will be to drop the device right then and there, especially if in addition to the smoke you feel some heat buildup, like it was somewhat cool a few seconds ago but now it's smoking and it's getting damned hot, fast.
Again, most people in that situation are going to drop the device immediately.
But your device has a removable battery under the removable back cover, right? So...
If you dropped the device because it was smoking and getting hot there's a chance, a small chance but a chance nonetheless, that in the act of dropping your device when it hits the ground or it lands on a desktop or table top it might just cause the back cover to pop off and the battery might just pop out of the device entirely. That's a possible thing, right, you can actually imagine that dropping a smartphone with a removable back cover and removable battery might just make the back cover pop off and the battery pop out.
Still following me? Good but here's my point.
If you have a smartphone and it starts smoking, anywhere - be it in your hand, pocket, dash holder, tripod holder for pictures, on a flat surface, in a pool, under water, in a toilet, desktop, table, gravel, dirt, sand, on a road, it doesn't matter - the primary way to get the battery out of that device means you have to remove the back cover and then remove the battery and that requires you to hold it but since it's smoking and getting hotter by the second that's not really an option anymore.
So what then? Does that mean having a removable battery is a bad thing? Well, no, not really, but in a situation where the device fails in some manner and causes - that's the important thing here, the cause - the battery to fail as well and burn itself up it means you could potentially suffer some injury yourself because you have to manually remove the back cover then the battery.
tl;dr Yes it's a good thing to have a removable battery, but if a device with a removable battery fails and you want to remove the battery during the failure hoping to save the device itself from further damage, you might be injured yourself because you have to handle the device to some degree to get that failing battery out before it does damage the device or in the most extreme situation explode which destroys the device and also might release the gases from the battery which are incredibly toxic to humans.
I'm just speculating here.
My answer is: Maybe.
If I read is correct and the fault lies with the design flaw more than a battery defect, having removable battery would mean losing water resistance and the curve design, and maybe not apply too much pressure on to the physical battery itself.
What I do know is, if we had removable battery, Samsung would have avoided a full on major recall and just exchange the battery. If size is a problem, maybe a smaller capacity in exchange for safety. And maybe a small refund or a token of gesture to make up for the smaller capacity.
Oh well. What a waste.

IF the battery is-was the problem then your question has an obvious answer. WE don't know yet what the problem is so no one can yet say.
Its yet more of these threads with yet more speculation over a done and dusted deal.

I do agree with broadband. Even with removable batteries, if the batteries were damage, I wont be fast enough to remove it to prevent total loss.
But yah, it will drastically affect the recall process. Recall batteries are still better than the whole phone. And there will be plentybof after market alternatives to tide over temporarily
One of the reason is also easy troubleshooting , but a faulty set is needed to test the theory, example a faulty note 7 came with a removable battery, reports states that it will get extremely hot before smoking up, sure many of you who own Samsung older version of phones, changing battery is quite fast if the techniques is right, ok just a example, if the first one is a sdi battery as claimed, went faulty, threw it off before smoking up.
Went to claim from Samsung, which is ampere battery(forgot the name), if it didn't does a thermal? What's the deduction then?
If the second battery did smoke up, high chance its the phone issue? Of course this is just a theory, with all the reported note 7 smoking up and burned like crisp, it's quite hard to csi it.
Based on my observations, it seems like the replacement units are more prone to blowing up than the original. Even with the ATL batteries.
Okay, hello XDA Forums peoples! Ive been lurking here for like a decade. I feel bad for bothering you nice people, but now I'm at my wits end with this phone.
Okay, so, long story short:
Z Fold 3, let it run the One U.I. 4 update, bricked the whole phone, wouldnt come back on. This happens a week away from being out of warranty. So i get samsung to agree to let Asurion/uBreakiFix repair it (I almost always fix my own electronics, I hate Asurion, I've had problems dealing with them before, but its free so whatever). Well they get it working, i asked what they did and they were basically like 'uhhh idk'. I assume it was just an 'unplug the battery and plug it back in' kind of thing.
Anyways fast forward to a couple months ago. Im walking along the creek, i always keep my phone in my backpack for safety. Zipper on my backpack comes open some, phone falls out and directly into the water for about 3-5 seconds. Goes black within 15 minutes. Alright, so it seems like maybe the boys who worked on this didnt seal it back properly. Whatever.
I let it dry for about 4 or 5 days. Comes back on, everything works except the front screen's digitizer(which is cool for me, because the inside screen still works fine) and its reporting too cold to charge, so now once the battery runs out i have a new foldable brick! Yay! I check the battery temperature thats reported in settings and its completely fine. I hit it with a hair dryer for like 5 minutes to try and trip the thermometer, and nothing happens.
I tried some cheap shots in the dark, i replace the USB charging board, i replace the wireless charging coil, both of which have thermistors on other older samsung phones, so i figured it was a decent guess. Still too cold to charge.
So I find a schematic, or not exactly a schematic, but like a boardview, i guess. So at least i know where the thermistors are to check them. Theres about 10 thermistors on the main and sub boards. 5 of which are covered by metal shielding which i am just terrified of trying to remove, mainly because i havent done it before. So i check the other half.
The thermistors used in these phones are like inverse, so they have less resistance for higher temps and more resistance for lower temps. If one of them is dead, it will have like "maximum resistance", right? Which would report the coldest possible temperature, right? So that all makes sense, to me at least.
The 5 i can get to with my meter to check, they seem to work completely fine. From what research ive done they seem to be like 100k resistors when measured at ~70 degrees f, and i can watch the resistance go up and down when its cooled or heated past that temperature. Okay, perfect. That all checks out.
Because the other ones are under some metal shielding, i assume theyre most likely fine because any water would have a harder time getting in there. So i skip to the most expensive option so far: i buy two replacement batteries. The schematics do not include the battery, so i dont know where the thermistors are on my current batteries to check them, if that was the problem.
Well, batteries came yesterday, i pop them in, still too cold to charge. I've already ran the phone dead checking it, so i cant do any further diagnostics with the phone on. And now the most i get is a Yield sign with a thermometer in it when i plug it in.
Okay, so... Idk?? This problem is starting to get over my head. What do y'all think? It seems like my options are becoming more limited and expensive.
I can try and put a big blob of solder on the top of the shielding and pull it off to check the remaining thermistors, which seems to be how people remove those things. I also have have hot air at my disposal, which is always risky with tiny things because too high airspeed might blow components away on the board and then i'll probably cry.
It could just be a connector somewhere on some flex cable? Maybe? I mean like maybe what if one of them is for reporting temperature, and water corrosion is stopping it from sending a signal through???
Im fine with doing whatever, but i just want a charged battery first so i can recover my data before i do anything that drastic. I mean, back in the day they had 4 big pads on a removable battery. You could buy a universal samsung battery charger or rig a USB cable to charge it, but I have literally no idea what to do here. Does anyone know of some specialized battery charger that will connect to these flex cables?? That would be a gigantic help right now. Or if i knew where to get a Z Fold 3 just to pop it open and charge my battery with? Or maybe just sit there for 2 hours holding two wires to the positive and negative pins?!??!?? I dont know. Someone throw ideas at me, please!
Might be worth buying a bench power supply and either injecting voltage through the phone or connecting it to the cells to trickle charge them back up? Im not an expert it these just throwing ideas
