Hardware Defect with USB communication and charging

I reciveved my phone yesterday and after playing with it for a few hours I charged it last night and noticed it became hot to the touch in a few minutes of being plugged in. Like burn your hand hot and there was a bit of a hot plastic smell coming off it. I unplugged it let it rest. Today I have no usb access to it. No adb, no fastboot. Lsusb shows no devices etc.

Xplodwild tweeted out the other day about issue with USB charging similar to this. Does the same happen when AC charging?

Is this problem similar to this guy?
Watch out for overheating!

seems to be a similar issue - it was very hot on the back side just below the camera especially I'm just afraid it got too hot and something was damaged.
This explains why google was pushing their bumpers instead of a full case I can't imagine a case would be good for this things thermal characteristics.
This happened while charging via ac when charging via usb it just seems to hold steady at whatever level the battery was.

Just out of interest, what surface did you leave it on all night?

I left it on a wooden desk for 5 to 10 minutes it didn't take long

It is no longer charging. I can't get it back to stock to rma I'm not happy :crying:

Woah, all other nexus 4 problems aside, this one is quite serious.
Just imagine what would have happened if you'd have left it on a easily flammable surface and wouldn't have noticed the heat. Worst case scenario might have been a fire or something like that.
If this really is a common problem (I've already seen at least two people reporting similar issues), we might see a big recall campaign quite soon.
I guess you don't really want the LiPo battery in your phone burst like this

Maybe Google should start to sell these bags instead of the bumper

Where you using the provided USB-AC adapter?
I know that my friends GS2 and GS3 got really hot when using my playbook wall charger (rated at 5v ~1.8A) :S

Heard of similiar issues with nexus 7, but the one I'm aware of is still charging.

I haven't experienced this issue yet?

I contacted google play they were quite happy to send me a replacement. Aparently they held back stock in case of a need for returns. HOWEVER they tried to charge an authorization hold on my account in the ammount of $350 I DONT HAVE ANY DAMNED MONEY I JUST SPENT IT on their ****! The only other option they said was to return it for a refund and wait a large number of weeks for orders to open up again or send it directly to LG for the same treatment ?!? I'm PISSED. The guy said that this was not the first case he'd heard of like mine didn't even ask any questions except for the serial number - I'd expect that there are going to be quite a few issues like this.

Yeah, sounds like my problem. Was your microUSB port also loose/creaky like mine? I got Google to RMA me a new one. It's a shame, I love this phone and this one has no give on the screen whatsoever and no rattle. The port though and the screen flicker are another story...

I don't have screen flicker yet and the port isn't lose I'm thinking somebody cut some corners on the voltage regulation

Damn, I guess this is sorta good news for all the folks (myself included) whose banks dropped the authorization, haven't had Google recharge us, and have the phone in hand.

About to get the Z1, how prevalent is the self-cracking issue?

Hey guys,
Title says it all! I am sold on the Z1 (Z2 too expensive) but the self-cracking issue got me worried hard...its the ONLY reason I'm not getting this right now, how prevalent is it really? Thanks!

I have never heard of it, don't even know what you mean.
And don't worry, I have already asked the mods to move your question to the Q and A section

Has anyone experienced this?

I can double the fact that I never heard about this. What is it?

He mean that the Z1 cracking the glass, front or back, by itself. Still unclear how, but someone said it happen on they phones.

Probably a chick that wears skin tight jeans and keeps the phone in their back pocket said it then wonders how the screen cracked lol.

It happens. Look at sony support forums. They say it was no hit then crack or it just cracked by itself.. Sony addressed the issue i think? I mean, they responded. I forgot their response though just look through the sony support forum.

Yea thats the issue. I just don't know how prevalent it is and who wants to deal with customer support all the time you know? It seems like they denied the issue at first but then they replace it in some cases.
All phones have problems but if its prevalent I'd stay away from the Z1, thats why I asked Phone looks amazing though!

My z1s cracked itself.
Went to sleep and when I woke up the back had cracked.
It doesn't affect usage so no big deal to me.

Hmm. maybe its a problem for a given batch of z1? Maybe they fixed or solved the problem in other batches, like productiob batches. Like cars. Sometimes they call a specific batch back to get fixed because of problems, then the other batches are ok?

Possibly referring to overcharging the device, the battery swelling , the phone bending and the glass cracking, if this is the case then I can tell you that if you don't overcharge your device (excessively anyway) you won't have this issue, the phone itself is glass but is relatively sturdy and a few knocks here and there won't give you any problems, a drop from height and you might have an issue.
Hope this helps.

What do you mean by excessively charging? Too many times or too much time per charge? Or both? Thx in advance.

Rubbish. My handset is almost permanently on charge either on my bedside table (from the moment I get in as it provides my Hotspot), my desk at work (I don't carry it around as I'll break it) or in the van providing handsfree and GPS. Most of this time it's got the screen ON and is being charged with a 2500mAh charger.
If one was too overcharge it would be mine and it never has.

Rubbish? Really? Well explain this then? This is due to excessive heat and overcharge and a bloated battery.
When the battery bloats it has no where to go, i've seen this many times on devices, namely the kit used to diagnose problems on BMW and mercedes cars uses a blue battery and i've seen them triple in size when overcharged and eventually the screws, the sides of the device split, So no not rubbish at all, do your home work.

excessive as in overcharging constantly, especially with a charger which outputs too much power. the battery will eventually bloat, this can't be good for the components inside, whether or not that this device in the article is due to that or not is anyones guess, but i've seen devices split from a battery which has bloated beyond its limits. This is usually due to a few factors, excessive heat, charge or water damage.
I don't know why but it happens, galaxy devices see this issue more than others.

The article says 'possibly'. It's not confirmed. One of the the things I was asked when my old handset went in for repair was 'is it bent?'. Obviously I said no and asked why, Sony's comment, on the phone, was that the bending people had experienced was due to people sitting on their handsets or putting them in trouser pockets and the pressure combined with heat was causing them to bend.
More to the point. The battery is towards the bottom of the handset. The pictures of bent handsets show the bends to be at the top, nearer the processor.

Read the battery life, conditioning and multi cell device sections
This describes the misconceptions surrounding Li-ion batteries (That are in our Z1's) including the fact that the software in the phone prevents overcharging and will also lead the battery to discharge whilst still plugged in order to give the battery max performance/life.
If a battery in our mobile phones is getting overcharged that will be a symptom of another fault, namely something wrong with the phone software. Our batteries will look after themselves, there is no need to worry
Here is another point about not completely discharging Li-ion batteries

Ok so the Li ion battery found in the device i was referring to bloated, it was plugged in all of the time, in a different dealer the same machine was cared for by not being over charged, and didn't experience the bloat? reports from several other garages of the same thing.
How do you explain that?

I am not trying to explain anything
Just pointing out some articles, from what I read in them the OS will look after the battery more than us, and that it is OK to leave it on charge without waiting until it is completely discharged. Then, about once a month you should completely discharge it and fully charge to calibrate the software
Maybe the chargemon file in our phones looks after the battery more than the software in those machines you are talking of, its the OS that looks after the battery

Not sure m8, all i know is that if phones are left to charge all the time they experience anomalies, any phone that's been left in a shop for a period of time will experience the issues, I know there are fail safes in place but issues still occur on all devices, primarily and the most noticeable is sporadic touch screen issues although the newer handsets have been able to erradicate this somewhat, but the bloating battery from overcharging is very real, if i'd not seen it with my own eyes then i would be sceptical too.
Whether this phone bending phenomenon is solely due to overcharging or not i''m not sure but i'd say it's definitely a factor.

excessive heat and sitting on the phone? I'd have thought that the glass would have broken way before that it bent, and the battery isn't on the bottom, it's from the bottom all the way up to three quarters of the phone. So it's actually a plausible theory that battery bloating could have caused it to bend.

Then I took mine apart it seemed the battery was more towards the bottom than the top. But it is plausible the battery could cause bending. Seems odd though as the heat would be greater in the centre of the battery, not one corner.

QI Wireless Charging

We heard rumors that it'd have wireless charging and now the Motorola Site doesn't list it on the Droid Turbo Spec Site.

It would be nice. I have an N7 but haven't bought a charging pad yet because I didn't feel I'd get enough use from it. My N7 battery easily lasts me a full day and I just throw it on the charger at night. No big deal.
I use a Moto X right now and tether my N7 to it on my daily bus commute (~2 hours each day) and I usually need to give the battery some juice before I leave work to have enough for tether on the ride home and the remainder of the evening.
When I get the Turbo, it will easily last a full day. I don't think I'd ever really need the full two days of battery life, but it would be great for long days. My Moto X right now can't make it through an entire day with my usage. I know I'm probably above the bar in SoT (usually 3.5-4h), but I average about 13h, according to GSAM over the last 8 months. Could use a nice big battery to keep me going for 18-20 hours.

I guess it does have wireless charging...
The new DROID comes with a turbo charging feature so when you’re low on battery, a 15 minute charge can get you up to 8 hours of use. DROID Turbo comes with the Motorola turbo power charger in the box at no additional cost. And for added convenience, the new DROID is wireless charging capable.

Awesome..thanks for that

Semi-related.. Can anyone suggest a nice charging pad? I've looked at them for my N7 before and the prices seem to range pretty widely. I understand they charge pretty slowly.. but are they all the same for speed? Does the device need to be perfectly aligned in order to charge? Can I charge two devices at once (N7 and Turbo)?
I'm thinking I'll throw a pad on my desk and one at home, either in the living room (coffee table/end table) or bedside table.

There are some features of a phone that you appreciate more when you have them than you do when you read about them. An example might be high speed charging, their are a few technologies out there for this but the bottom line is when you have it you really come to like it. Its very nice when you have forgotten to charge your phone and you suddenly decide to go out to be able to get a charge on it that will see you through in the time it takes for a quick shower. When it was new and I first read about this it sounded good but no big deal, I usually make it through the day fine and charge over night. Now that I've had it though I really like it.
This is kind of a long way to get around to it but wireless charging is the same way. Its very nice to simply have the pad on the night stand or wherever you may put it and drop your phone on it without having to plug it in. It seems like nothing much but once you get used to it having to plug in seems like a bit of a hoop jump. One benefit of wireless charging that often gets missed is port damage, I have had more than one phone in the household that met its demise by tweaking the micro usb slot so that it either wouldn't charge or couldn't transfer data or both. My understanding is we will still have to plug in to get high speed charging but the ability to do both if we want is a very good thing in my mind.

Good points. I held off on a pad for my N7 because the battery easily lasts me through the day, two if needed (I usually charge it every night, though). Even though the Turbo probably wouldn't need to be topped off during the day like my Moto X would benefit from, it would be nice to have the option. I agree on the Turbo charger too. Great in a pinch if you are at an airport or something and just need some quick juice for a flight or something.

3.9Ah batt's gonna take a long time to charge with a 700mA limit though.
Should be OK overnight. Then again if it's only discharged to 60% when you start it shouldn't be hateful.

Yeah, wireless charging works best where/when you are going to set it down for a while such as over night or when you place the charger where you set your phone in the evening. I used both, one on the nightstand and one on the end table by my chair. In the latter case it is quite convenient since you can answer a text or what have you and simply set it right back down and its charging again. This is why I think its a great feature to have both wireless and high speed by whatever name, they should complement each other well. I say should because I've had both but not on the same phone, I'm really fairly stoked about this handset for this and other reasons.

We need something like this.

Obviously not this particular one, but something to split the micro usb so we can charge the phone while using the VR, which is my only real issue with it, aside from phone warming up pretty bad.

It probably would be easier to modify headset itself and build charging port into headset or some kind flat cable with microusb on one end and another end could fit betwen battery and phone contacts or maybe someone discovered which are charging pins under back cover (used by charging back)

Agreed, really wish samsung would have added charging, the only real downfall of the VR.
How about the QI mod I've seen people talk about? Seems like a good idea, basically just stick the pad in the front of the visor, aside from health risks from doing this lol, I'm worried that the VR will drain the battery faster than the QI charger will charge, but if anyone has any experience with it, I'm all ears!
Hopefully, the next version of the VR will allow charging.

They need to figure out the overheating before dealing with the charging if its hot already, imagine how much worse it would be while charging! At least we can quick charge!

There were concerns about people strangling themselves while charging the phone with a cable. And the additional heat is probably also a factor.

Well the samsung demo booth had a battery with a cord and a special cover with a hole in it. The cord was mainly for security (the battery screamed when removed from the phone, which the guy setting it up had to do to reboot it occasionally), but I'm pretty sure it also supplied power, since it was the only one in the booth and the thing was running all day long. We might be able to make our own usb-powered battery blank. Not only can we then do external power, but it should also help remove some heat. If there's enough room you could even add a peltier

I know its more money but invest in the official battery kit. If you're serious about using VR it's really the smartest option especially if you're showing off at a party.
I was watching this live YouTube stream and the guy was killing me with his low battery issues. It takes a minute to swap for hours of entertainment. And your depleted battery is charging as well. I bought mine at bestbuy because Samsung is always out of stock.

Wireless charging easier?

Is having a wireless charger truly easier than just plugging it in? I've also heard of people using a charger in places like under a table or couch and being able to charge their device without seeing the charger. Is this true? Cool if so!

I Just Got the Speigen one last night. Its nIce To sit down when going to bed. It IS slow though. I have the ampere app which measures charging. When on the Samsung wired charger input hovers around 1000 to 1200mah. On the wireless it is all over the place from 100 to 350mah. I've seen it as low as 10mah. So it's really something to just set it on before bed unless the Samsung on has a much better charging Rate. I got that one half price in exchange for a review so the Samsung one may be in my future if it charges a lot faster. It does however work through my ottorbox. Those higher numbers are bare phone though with no case. This one is supposed to be strong due to the 3 coil design. I call BS.
Now there are websites that sell the 3 coil parts so that you can make your own or integrate it into furniture. I'm thinking about ordering it so I can build it into my center console

I have both the Samsung Fast Charging and Choetech Fast Charging wireless chargers and love them both. For me, they both charge fast... comparable to the charger that comes with Note5 I have and S6 E+ my wife has. I have no complaints from either about their performance.

It's easier once you get the hang of the "charge zone" on your phone. If you don't set it down properly on the charger then it may not charge.
I have one at work and at home. I just set it down and don't have to have and loose usb charging cord hanging around when I am not charging.

Does anyone know a good wireless charger that its light can be turned off while charging? I can't stand lights on when i'm trying to sleep at night.

I made an accessory for mine. It fits the case perfectly and provides perfect alignment every time, even in complete darkness. Engineers, pay attention:

The three coil design only means a larger charging area, I have the same charger, unless yours is broken I don't know what your are calling bs on. Compared to my old ghost 100 that I had to meticulously place my nexus 6 on this one is pretty much just drop the phone on it, landscape or portrait and it charges fine.

I have a glass table in front of my TV that something like this would work great on. Now that they are so much cheaper than before, any recommendations?
