Electric charge in the case while charging

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.

[Q] Dropped in water, Wont charge anymore

My friend dropped her phone into a glass of water. Stupid her just had it off over night with battery removed, but next day decided to just pop battery in and start using it. Calls me later(spare phone) and tells me details.
I go get it disassemble, rubbing alcohol, the works. Let dry for 48 hours. Everything on the phone works other than it wont charge the battery. She has 2 batteries one which is new. Besides getting an external charger for it, is there anything else I could do to fix it? Is there a part I can replace, or something software related that might fix it?

I suspect (hope) only the battery was damaged from your friend's phone. Have her go to TMO and see if they will let her test charge a display Slide battery in her phone. If it starts charging and increases by a few percentage points then perhaps only the battery was damaged. Hope the situation gets worked out.
Just dropped mine in a full sink two weeks ago ... mine hit the edge and knocked the battery out milliseconds before the device hit the water (miracle). Fully submerged. Dried it over a weak heater vent for 2 days. Works just like new. I figured the phone was ok as I snatched it out of the water very quickly. My main concern was the battery ... I thought I might have damaged it. So far everything is just fine.

We have tested it with a new battery. Phone works perfectly fine just wont charge the battery, every feature works. Can even connect to computer with usb.
What im trying to figure out is if there is something I can do i.e. fix it somehow cheaply

Your best bet is probably just using an external charger. I'm using a friends old phone that had a full glass of lemonade spill on it and sit for 5 hours in liquid, turned on. When he woke up the battery was sparking, contact was melted. The battery was partially fried from the short circuit, so I just bought a new battery. The only thing that doesn't work in the phone is the camera. The real downside to that is if any app tries to access the camera the phone completely locks up, takes about 10 seconds just to get out of the black screen.
I'm digressing, anyway, yeah, external charger is probably the best bet, if she has two batteries that should work just fine. Use one while the other is charging.

ultrasonic cleaning
if you disassemble to the charging circuit board or motherboard and try placing it into an alcohol solution in a u/s cleaner (also used for jewelry), this might clean the contacts and allow charging, might not do anything or damage the board. no guarantees on this method , but will sometimes work.
ps. remember that some circuit board cleaner solutions will dissolve plastic, recommend alcohol.

The best solution I have found for a wet phone, or any device for that matter, is to take the device apart as much as possible. Then put it in a ziploc bag of rice. Seal it up good so air doesn't get in. The rice will suck all the water out. I have done this with my old G1 (twice) as well as other phones.

Charging Issue

Hi guys,
i have some issues with charging my inc2.
it is not accepting any charge anymore, tried diffrent chargers, cables, even on my pc but nothing. The orange charging LED just flashes slowly on and off...
Any ideas?

Need to replace phone or replace charging port.

Yes, unfortunately it is a known hardware issue. Over time, the charging port starts coming loose. Like mentioned above, you CAN fix it yourself. There are video tutorials on YouTube and the replacement part can be had for under $10. If your device is still under warranty, Verizon will replace the phone. If it's not under warranty (or if you just want to give it a go), the port replacement process is pretty straightforward.

I might give it a try. Does anybody have a video or a link?
The weird thing is, that the battery is discharging very fast, could it be just a bad battery?

Could b the back door on your inc 2. I believe you need the back door on to charge cuz it goes thru contacts on the back. I dropped mine one day and charging and getting signal was almost impossible till I figured that out and bought a new one

Ok.
Seems to charge now. Won't touch it until it is full. After that I will check what is going on.
I don't know where this issue came from.never dropped it nothing. It was even in a Otterbox

The issue stems from regular use. The charging port is essentially held in place only by the connections to the board. Repeatedly plugging and unplugging the power cable causes it to break over time.

actually just replaced the charger port on my incredible 2 today. It really wasn't that difficult at all. If you have any questions feel free to PM me

yeah it has to be replaced. happened to me last month. It's honestly like the worst flaw with this phone

Def need to replace it. Same issues I was having at one point with it randomly taking charge. I found that if the charger is plugged in a held a certain level ( i placed the phone on a flat surface with a book under the cord for leverage) it would charge just fine.
If you are rooted and sending back, make sure you revert to stock to avoid any annoyances.

I've managed to solve this issue without messing around with the phone's innards (the last time I did it was a disaster and I was forced to buy an entirely new phone). It's not pretty, but if you twist a rubber band around the micro usb end of your charger, plug your phone in, twist that same rubber band around the phone itself, and make sure the connection very tight, you might get some more life out of your charger port.
Ugh. I can't wait for my upgrade.

Nice name there Dave.

While, I give you major kudos points for MacGuyver-ing a solution, that's more of a quick band-aid than a real fix. I could imagine having a rubber band around the phone could potentially hinder usage.
But hey, way to think outside the box! :good:

Thank you. You're telling me. Do you know how hard it is to use a touch screen with a rubber band across it? Oy.
Right. The caveat here, of course, is that this technique will only help charge your phone until the charging port becomes so disconnected from the board that no amount of force will reestablish this contact. And this will inevitably happen because you're going to keep plugging and unplugging your phone from the charger which is what created the issue in the first place.
If you know you have big, sweaty, idiot hands (like me) that are going to destroy your phone if you take it apart (like me) and you can tough it out: more power to you. The other alternative is to buy an external battery charger and a second battery. The disadvantages here are pretty obvious (e.g. you have to carry a second battery around; if you forget a second battery, you can't ask another Android user to borrow their phone charger, etc.).

Battery Drained Rapidly Problem

Anyone encounter this problem when u r not touching your tab, and the battery drops drastically without any app running in the background? See picture for details.... see how it drops drastically in within 10-15mins at 0922hrs....

Happened to my 8.4 Tab S once. Haven't figured out yet what caused it. It was basically after an OTA. I rebooted the tab and haven't seen it since.

I rebooted alot of times m itz the same... i guess i have to reflash it again.

I had this problem when i first got my Tab S. After turning off the Automatic security policy updates i had much better battery life. Its under Settings > Device > Security >Security Policy > Automatic Updates.

Ok guys.... read this....
100% -70% in 40mins. (Listening to Music and surfing web)
70% - 50% in 20mins. (For no reason)
50% - 5% in 25mins. (Played game and installing apps)
Off it, plugged charger to it. Was surprised that it shows 48% instead. Let it charge for 2 hours. Was 87%.
On it up. Accidentally pressed the Launcher option instead of Touchwiz Home. Restarted it.
Battery shows 68%, and drop to 47% in just 3mins...
This is what I'm encountering most of the time... any ideas as to why it is like this?

Got this same problem before wherein my battery acts nuts. it would suddenly jump off from a certain percentage just like yours, sometimes, it Would show 1% and will shut itself off. Then when you turn it on, it will have at least 30-40% left. Quite annoying. Tried all battery wipe tips here. To no avail, until someone advised that he pried the back cover off only to find out a loose battery terminal . I did the same (carefully) removed the connector and reinserted it firmly. Discharged the whole battery using the tablet to around 5%. Turned it off and charge it to 100 without touching. Now it last for 2 full days (2days 10hrs) under normal usage and i'm using it as my primary phone. Listening to mp3s via bluetooth willshave off 5% in 2 hrs (with at least 20 sms sent). Playing movies in full brightness will shave off 10% (standard 2hr movie)
Before: notice the sharp, perpendicular drop - and the pulsating voltage on the last part of the graph
After: more than 5 hours, no percentage drop
Normal use, yeah, i dont use it with screen on most of the time, i simply listen to music via BT. and always on wifi
Else. If it's under waranty. Try to bring it to your service center and have your battery connector reseated for you

I DIY'd mine so it's possible. You need a prying tool (the one that looks like a guitar pick) simply start from the buttom (where the UsB port is) and make your way around the tablet. please be advised that some of the clamps run towards the center of the tablet so you may need to stick in your prying tool deeper. Just be careful and take your time, and try not to break any of those locks/clamps.

No warranty sticker found on mine. Prepare a double adhesive tape since some of the back cover part (near the IR blaster) is held by a non-fixed adhesive. Just be sure to angle your pryer towards the back cover and be careful not to wreck any of those clamps

Heh... i ald broke one clamps. Lol!!! Anyway i realised something. The battery connector (in the pic i posted here now), the metal connector which is out of the box, is connected to the mobo. But i had to press it down. If i don't the tab doesn't starts at all. Is there supposed to be anyting there to hold it tight between the back cover and the part there?

This is the connector from battery. Sorry my drawing is not perfect

check out for blockage or any thing that hinders the wires to sit properly with the board. when i lifted mind before, there's a small chunk of plastic material the broke off the connector and went straight to the board where the connector is suppose to sit, i removed it then i sprayed contact cleaners on the wire-terminals before re-seating it on the board would you be able to take a photo of your board/contacts?

i am on my way home. will be back in 2 hours time. what i can tell u is that i had to put something on top of the box connector so that when i put back my back cover, it makes contact to the board. if i dun, my tab will never turn on....

1st pic: As u can see, i accidentally broke one side of the holder.... lol!!!!
2nd pic: Even thou it looks like itz touching, actually itz not. No matter how i try to it just wouldnt touch.
3rd pic: i have to fold a small piece of paper to make it as a tightener between the cover and the connector to make it connect to the board. The one that does not connect properly is the left side.
If problem still persist i guess i really got a defective battery. Will get a replacement when spare parts are available on market. I don't wanna spend fortunes on samsung repair center.

oh my, you pry the board off, that needs to be re soldered.
disconnected terminal

This is the whole thing when i opened up my cover. That iz y i say the whole thing is out.... it is already like that.

same problem ?
I think I have the same problem.. I'm just scared if it is because I rooted my device...
I have bought a otg cable to connect my ps3 controller to my tab s . That's drained my battery in a record time but I wasnt thinking it was problem.
I played with my ps3 controller and tablet until it shutdown iteselft. I plugged my tab on the wall right after and it shown 45% ... I restarted and sames battery life was showing. The app I used is sixaxis enabler.
I let it charge up to 90 % and watched movie. The battery drained quickly too..
Will do somes tests to be sure if it is normal or not...
Ah before to forgot I watched movies before and the battery seems to have decreased quicker.

Question Z Fold 3 'Too Cold To Charge' after water damage

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
