'Shocking Sensation" Low current running through backcover while charging

My sensation has a low voltage current running through the cover while charging. When holding the device while plugged in you get "shocked" (its better described as a tingly feeling). I did not have this problem before but i first noticed it after i got my sensation fixed by Vodafone. I send it in for repair and i don't know wat the exact problem was but they replaced the whole motherboard.
Does anyone have or had the same problem or have any ideas what i could do about it because i don't really want to sent it in again after last time when i had to go without my phone for 3 weeks.

Charger is probably defective. AC current should never get to the phone, but is coming in thru the ground in the charge cable.

or as the antennas are in the back cover this could be another issue?

I have the same issue when I charge the phone with a 3rd party dock. I can't remember having the issue with the AC charger. I'm going to test this tomorrow. However, I don't see this as a problem.

I dont think it is the charger because it also accurs when charging via my usb port on my laptop with a different cable. Its just so weird lol.
Maybe it is indeed the antennas. I will try with a backcover of the sensation of a friend of mine, when i have the chance, to see what happens. It is not really a big problem but i'm worried this will lead to other problems.

I also facing the same problem since beginning of buying this sensation. I'm using the stock charger that come with the phone. I think this is normal. Its happen to all my phone before (HD2, Desire, DHD and now sensation).
No others side effect happen from this tingly feeling to the phone.

Stock psu provides 5V DC.
One suggested solution is carefully bend up the silver contact on the back of the phone.

yes bending the contacts works, and you're good with soldering iron try putting some solder on the housing itself to give full contact to the back housing. works for me and there's a thread on this (with pictures too) try a search for that thread

I get it too charging via USB. Its like a static shock in the wintertime when you scuff your shoes on carpet and touch a doorknob.

This issue may be due to it being repaired, I mean everyone has an off day and makes a mistake. But also you are not the first person that has posted noticing the tingling sensation you get when you are charging your Sensation either. So who knows this could be yet another small problem us users are finding with the device, I have not passed judgment yet.

This is highly unlikely, most standard USB wall chargers do not have a ground prong to connect to insert into the ground terminal of a wall receptical. Also a USB cable only has two wires for power transfer. Meaning one is for the positive and one for the negative to complete the circuit. Not to mention if this was the cause the OP would not be complaining about getting a tingle, but of constantly having to re trip a breacker or replace a blown fuzz.

I don't get shocked if I touch the phone while it's charging but if I touch it with the dorsal side of my finger/hand there is a slight buzzing feeling, like a high frequency, low amplitude vibration. This only happens if I touch it with only one hand/finger. If there are more contact points, the buzzing feeling disappears. So when I pick up the phone the buzzing disappears.

Battery suddenly dead on both dock and tablet

Until yesterday, my TF700 was working perfectly fine, but now I'm concerned as the battery in both the dock and the tablet have stopped working.
The AC adaptor's connected to the dock and I always charged both the tablet and the dock together for the most part.
I went to check the device this morning and suddenly found that they're not working at all.
Yesterday evening, I tried switching on the tablet and it would switch on and reach the ASUS screen, but not fully boot up.
I bought it from Amazon's Amazon Warehouse division and I have until the 31st to return this, but in the meantime, I'd like to know why the batteries have died on me suddenly and is there anything I can do about it.

If it's a genuine hardware failure, you'd have to return -- unless you're very proficient at handling and replacing sensitive electronics yourself (microwelding, for example).
It has been reported before, and could be fixe din almost every case by letting the 700 be dead for at least an hour, and then let it fully charge while off (!) -- just let it sit hoked up to the wall charger for at least 8 hours. Then try to turn it on again.
Good luck.

It never hurts trying -- you aren't exactly the first to describe this, but luckily, pretty much all of the others were saved.

I finally managed to get the problem sorted out as it seems that the connection to the port on the keyboard had somehow come a bit loose without me noticing it.
Unfortunately, I have a new problem in that the cable itself seems to have died in that it won't work any more with the adapter as it started crackling a bit when I knocked the connector attached to the AC adaptor itself gently by accident. :crying:

Well, I hope I am right in assuming this is not your luckiest week, huh? Is the cable damaged near the wall charging part? (That's what I understand.) The replacement cables probably are not that expensive, so I'd plonk down on a new one instead of initiating "daredevil repair mode".
Saying that gives me that MacGyver feeling. Duct tape and a pair of scissors would be all that he needs to fix this.
Oh, and maybe a pair of toothpicks and an old sock, just for looks.

The cable itself is fine (it's not worn down to the wire literally like a lot of cables and AC adapters you get for devices like iPods and Galaxy S II's), it's just that it has this weird burnt-like smell at the end connector that plus into the USB socket on the AC adaptor.
As for replacement cables, I'm surprised that they're not that easy to buy offline.

Agreed -- buying them offline is a definite hassle. I have seen them online, though, and you can even hunt down the charger parts or the TF101 and TF201 Prime. They will work flawlessly.
BTW and FWIW (gotta love acronyms), my charging cable smells a bit funny at the end too. This specific one has to put through a lot of power, so I'm not even that surprised.

In all seriousness though, I love my TF700, it's just a shame that it's such a pain in the ass (not literally!) to buy official accessories in the shops and it's not as if you can buy a USB cable for it in the shops unlike ones for the iPod, iPad and iPhone.

Just giving you guys a update concerning my device: It seems now that both batteries don't want to work any more for some reason or other as of yesterday. I've checked both the official USB cable and a third-party cable plugged into the official USB plug and they're not charging up the device at all.
The tablet can connect to my laptop as a media device without any problems, but I'm confused as to why it's not working at all when plugged into a USB adapter.
In any case, I'm going to order a AC adapter from eBay later today and see if that works or not.

[Q] Need Replacement Charging Port

The tablet needs a new charging/interface port and was wondering if anyone knows where I can get one?
I have searched Ebay and the net for a used/new one. The port looks fine but when plugging the cable in it won't charge. Sometimes I can get it to if I push and hold it just right however this is tricky to do and does not work often. So right now it is a dead brick. The pins must not be making full contact for some reason.

Ive bought parts from these guys before, I don't see a charging port but might be worth giving them an email and asking

Thanks but I would rather not have to order parts from Sweden. If I have to I'll just keep watching Ebay. Every so often one pops up but doesn't last very long.

Good luck
The parts I ordered took about 4-6 weeks to arrive iirc

Just installed a new (used off Ebay) charging port with fingers crossed that it will allow the tablet to charge. I also have a new high quality charging cord (PWR+) and two ASUS wall chargers that I know work. Plugged the tablet in and was relieved to see the tablet come right on and show it charging. Let it charge to about 20% and then decided to unplug it so I could put the ring back on the tablet so it is all back together. Get the ring on and plug the tablet back in and nothing. I'm about to throw this thing in the trash right now. So fed up with these charging issues. What changed? All I did was unplug it, put the ring on, and plug back in.
So for kicks I decide to try the other wall charger and what do you know....it came on immediately and started charging and is still charging. I'm afraid to touch the thing now. Seems once it is charging and undisturbed it will charge to 100% no problem. However, when going to recharge it won't charge. Could there be something in the charging mechanism causing the thermal to trip in the wall chargers? Is there possibly a small short somewhere in the charging mechanism? Anyone have an opinion on why this is happening? Only other thing I can think of is doing a full wipe/reset and maybe flashing another rom (is currently on newest Android Revolution HD) once it is charged up.

Could the ring (I assume you mean Bezel ? ) or the screws near the port be shorting the charging port to earth/ground/chassis ?

Yep.. Sry.. The bezel. Not sure how but anything is possible. Would indicate to me a faulty charging port or charger cord and is happening on multiple. Tablet is still allowing me to charge it at this time after switching chargers and with the bezel on so will have to see how it goes.
Sent from my tricked out S4.

Fingers crossed it was a coincidence with the first charger, if not, I'd try taking the bezel off again and see if you can spot the short / see if it works again with the bezel off, or even just with the screws out

[Q] Would wireless qi mod be possible?

So I noticed the wireless QI receivers have started becoming literally paper thin lately.
And with this girls teardown, https://www.youtube.com/watch?v=dweww9_RF2E#t=224
I think it looks like you could remove the thin plastic over the battery, and fit a QI receiver there.
Thoughts?

we wouldn't be able to remove that plastic piece because it hold the battery, but it is stil possible. i already did recon on some places to solder in a wireless charger.

Curious, but I'm looking at the flat cable that just lies there, under the M-logo. It doesn't appear to have any PCB at the end?
I wonder if they were thinking about adding a QI coil there, but decided it was too expensive?

That's my theory since the nexus 6 has wireless and they are the same chassis essentially . or it was for a fingerprint scanner they abandoned. Once we see a nexus 6 teardown we will have a better idea if we can do it.

Could have sworn I read somewhere that between they cable and a teardown of the software showing code for a fingerprint scanner, the original idea was to have the scanner. I could be wrong though.

Let's hope you're wrong then.
It would be really cool to have wireless charging, shame so few manufacturers add this.
The amount of stuff needed to make the coils on the receiving end is pretty limited, I could absolutely accept buying the transmitter separately, (like the turbo charger is now)
But I suspect the patent royalties are expensive, patents sure don't benefit users..

Looks like the nexus 6 has a different config then the moto x so as far as a plug and play solution, no. I have located 2 contact locations where we could solder in a qi coil. I'm just trying to work up the courage to try it lol

Here is a related question: without modding the phone itself on the 2013 and 2014 model I cant get one of the QI receivers to work. This is the one for sale on eBay / amazon / newegg with a micro usb end to plug into the micro usb port. It literally works with every other micro usb device i own including a Samsung bluetooth headset, several phones and some other stuff i cant think of at the moment... On the moto x 2013 and 14 I literally see no charge and see it actively loose charge over time with this device plugged in.

It may be tricky with the moto x. There are some negative and some positive reviews here for example: http://www.amazon.com/gp/aw/cr/B00MN3RR7Q/s=sd/ref=mw_dp_cr
There are also some reviews saying they needed to restart the device once while on the charger: http://www.amazon.com/gp/aw/review/B00H7FJX7M/R2YPDLOU1BD4QE/ref=mw_dp_cr?cursor=2&sort=rd
You can find more of those comments on the internet. Could you try that, and if it works clarify if you need to restart it every time you want to charge or every time you connect something else?
Here is another link for the original moto x: http://www.reddit.com/r/MotoX/comments/2gskxw/original_moto_x_wireless_charging_mod_qi/
Edit: you may need a screen lock, e.g. the pattern lock.
http://forum.xda-developers.com/showthread.php?t=2596469
An unrooted Moto G needs to be screen locked (I use the pattern lock type) or it will refuse to charge due to the missing pins. You can unlock the screen while it is charging as long as you don't lift it from the qi charger. (tested on 4.3 and 4.4.2, DE and FR firmware)

Well chaps, bad news. I don't think this is going to be possible. I spent 6 hours today trying various solder points. Couldn't get any of them to actually charge the battery. Seems to be some sort of system configuration thats interfering with how its detecting .

Did you look at /sys/module/msm_otg/parameters/floated_charger_enable? It might not be enabled. Here's a similar thread for the Moto G:

As far as I know, wireless charging won't work without a pattern lock or having that option set. My Moto X won't be here until next week so I can't do any testing until then.

I tried pattern lock, didn't help. Wireless charging does not require a lock, my girlfriend has a droid maxx and wireless works without it.
As far as the module check, I don't have root on Verizon so I wouldn't be able to test it.

You are correct about wireless charging in general. I think the reason the pattern lock is suggested is because the wireless mod (even without internally mounting it) only provides 2 wires on the USB connector. Something about only having 2 wires, and not the data pins, is why the locking is suggested.
No worries on the module, just something I had seen while investigating. I don't know if the Maxx supported wireless charging out of the box, but it may have the flag enabled by default (that flag seems common among many Moto devices).
I'm coming from a Nexus 5 and I'll really miss wireless charging, hence my questions to you

The Maxx has it built in from moto, same internals as the moto x essentially. If we get root I could look at the module thing. I was lucky that I had access to a spare moto x main board so I didn't have to solder on mine. That won't be the case in the future.
I'm going to post all the points I tried so maybe someone can figure this out. I was able to get it to show charging but only right after reboot and it would stop once I took it off and replaced it. I have to emphasize it showed charging but never actually charged the battery, it would show charging in battery stats bit not in the status bar. I also use battery monitor widget to check the current and it never showed positive charge current. Once I was able to get it to details at as a USB charge, only happened once, still didn't charge though.
This all makes me think there is something screwy going on.

I ordered a Pure Edition (Cyber Monday deal was a great one) so if nothing else I'll have root to poke around. Pictures of where you tried would definitely be helpful. I think I saw some from you in another thread, but all in one place would make searching easier
A 5V near the USB port would be ideal because then we'd know its likely feeding into the battery or charge circuit. 5V elsewhere on the board may not be wired to the battery. Looking at the photos in that Moto G thread may give you an idea on where to poke around with a multimeter.
The charging after a reboot, and until you picked it up, sounds like maybe you did have it at one point. That whole "until you pick it up" is another thing mentioned by many in those Moto G threads.
What wireless charging receiver did you use (not your base station)? The one I ordered says "up to 1000mAh" but I had seen some at 500 or 650. A lower output rating may not be enough to charge the battery at all. One way to test this would be a very low output wall charger (one that puts out 500mAh for example) and see if the X shows charging when connected to that.
On a related note, how hard is it to disassemble the X? Some of the teardowns look like it could be a pain.

i've attache da picture of the points i used and the results are as follows.
1. shows 5v when plugged in. when wireless coil is attached to it, will power the phone up without the battery connected (doesn't boot, just shows a battery on screen)
2. pretty much exactly the same as spot 1
3. shows 5volts but doesn't power the phone
4. shows 5v but doesn't power the phone
5. you can't see it in the picture because the rubber cover for the usb port is on but there is a diode right behind the usb port. this one is the only port i was able to get it to say usb charging ONCE. other then that, acts the same as 1 and 2.
again i have to emphasize that even though they show charging initially, they never actually charge the battery.
I'm using a galaxy s3 qi insert 700ma. i think there is a mislabeling on some qi pads saying 1000ma but not considering the 30% loss in inductive charging. even ones with 1000 on them tend to charge around 650ma. some label including the loss.
As far as teardown it's not too complicated to get the back off, lots of adhesive so be careful to not bend the back cover. i have leather so that was a particular hassle as i didn't want creases in the leather. after that there are 17 screws to remove. i've included a picture of the ones you need to remove. the ones around the silver ring on the "moto" logo don't need to be removed along with the silver screw for the buttons.
after you remove the screws and disconnect the buttons and battery from the board the back battery plate comes off in one piece. one of the particularly hard parts about testing points is you can't turn the phone on because the power button is part of the battery plate. also when you put the battery plate back on and you have wires running to contact points it won't fit because there is a speaker "box" that sections off that circuitry. i combated this by using copper tape to essentially make my own tiny custom circuit pathways leading out of that box where i then could attach wires and run them up through the hole that the battery connector goes.
THIS IS NOT FOR THE FAINT OF HEART!

i'm going to write up a tear down guide for this phone. what section do you guys think i should post it in?

Spare charger for the s2

Anyone have any recommendations. That DON'T heat the watch up.
Somewhere on one of the android forums i found some links and ordered one. Just got it today. My stock charger is plugged in to the pc. Which we all know is small on amp charging. I tested the new unit out. from 90% to fully charged. And the back of watch was HOT. Too hot for my taste. I'm a long haul trucker so it will be my spare for the truck to take on the road. IT will be plugged in to either a 1 or a 2 amp charger. BUT, if the plugged into the pc made it that hot. I don't even wanna see how hot it will get by using a stronger charger and charging the watch from dead to fully charged.
So, for any of you that are using spare chargers. What's the recommendation?
If i remember right, some of the posts on that other forum mentioned the watch would get hot. But that's a little TOO hot for my taste for a 10% charge off the pc.

Hey snowwy66!
I bought an additional charger for my work desk and used several times already with good results (watch don't heat up very much, and charging process is nearly as fast as with the genuine stand). I just want to mention, the watch is charged by my computers USB port, so the charging current is 500mA (while the genuine charger provides 700mA to the stand).
I bought it in Amazon, just look here.
And as an annotation, a quick search would help you too, cause there is already a thread concerning this topic.
Best regards

i couldn't find the thread. Thus, i said thread SOMEwhere.
The one i bought, looks just like yours. Bought from amazon. Came from China.
I did find this sight though, looks like a stock samsung. http://www.mobilefun.com/50040/samsung/gear-s2-smartwatch/chargers.htm

Seems legit, but a little more expensive than the replica. My watch is charging right now and stays cool like the weather outside ^^.

guess it's not the same as yours. The one i got has a little tiny led at the bottom and didn't turn green when charge, instead it turned off.
thanks silber.

Looks like a counterfeit. I strongly recommend to NOT charge your watch with that charger.
