why? why did motorola use a proprietary charging cable? it would of been so nice to have a micro usb cable to charge the xoom. im very worried one day that needle proprietary cable going to break and it wont charge my xoom anymore.
it seems like motorola is a HUGE fan or proprietary cables, especially the v60 series flip phones.

Simple, many recent tablets use proprietary cables to allow higher current and faster charge times.
The average usb cable hooked up to your pc provides about 500mA
The proprietary cable for a modern tablet like the XOOM can deliver around
1.5A
With a micro USB cable it would take forever to charge the XOOM. Then people would be complaining about why the XOOM takes so incredibly long to charge, and bashing motorola for the problem. Instead Motorola chose to do it the intelligent way, by separating the charge function to a proprietary cable to allow very fast charging, and including the usb cable for data transfer.
When I see a proprietary cable I don't think - crap why do they do it this way. Instead I think wow great, that means this thing was designed for fast charges.

THANK YOU lol finally someone that understands.....
plus, the input voltage in to the tab is 12v, hard to get 12v from a 5v USB supply...
For a bit more info, I too wondered about USB charging. The limit seems to be when the Xoom is running, the current drain can be upwards of 400 mA so I could see a situation where a USB charger at 500 mA would overload if you did too much on the Xoom during charging. That would be good enough reason to avoid that design mess. "Do not use during charging" would not be sufficent protection. The Moto Mains Charger manages 1500 mA for a couple of hours which is wonderful. Now if only I could charge my Nexus S that quickly

right? about time
I am really glad that trickle charging is not possible with the Xoom, saves a lot of problems...I just wish they had used a different connector for the power. Something a bit more durable and commonly included in third party multichargers would have been nice...but one can't have everything.
I still support the seperate power cable choice for all kinds of reasons.

Just amazes me that folks will complain about anything and everything. Good grief, it charges in no time and runs more than a day when it does. What more can you expect?
I like the idea of a separate charger, but the only thing I take issue with is the design of the charger it self. Luckily, I just set mine on the dock before bed. The dock doesn't use that flimsy pin, it uses the two gold plates at the bottom to charge.

going to have to look into that dock cause i'm not to fond of the charger that it has. so the avg. use time is about a day, are you guys mod or heavy users(as you can tell i dont have mine yet ordered and waiting for it to show up)trying to get as much real world use info as i can
i love the proprietary cable. It is SOOO much faster. My Galaxy tab with a 4000 mAH battery took almost 4 hours to charge and i was lucky to get two days usage out of it (standby time and normal usage combined). My Xoom (no idea on mAH size) charges in 2 hours and i get 90 hours usage out of it (mainly standby but still a lot of screen on time, wiht a much larger and brighter screen to power). LOVE it.
Yeah I wouldn't worry about the Cable its seems durable, only thing I AM worried about was how you plug the wires all on the side of the device, I feel like there's abit of give on the wires when holding it sideways, I wish it was more like the iPad.
You know the first time I saw that the tablets used a seperate charging cable I was like, "why?" but then I stopped and think, there's no why a USB (let alone a micro-USB) can charge those suckers, so I'm personally glade that tablet makers did what they did and make it seperate.
I just wish they chose a 30-pin connector instead of this tiny one. The slightest mistake while it's charging (like say you trip over the cord), and there goes your xoom for repair/replacement.
Lets not rule out USB charging. Yes, I love going from 5% to 100% in about an hour. But I also have USB plugged in for hours on end when doing my thang. . That being said, we do not know for certain that USB charge is a hardware limitation. Yes, USB puts out 500mV. But I can tell the kernel to suck in whatever. If the hardware is capable, its doable.
I still think the option should have been given to us. Cuz many if not all of us have micro USB around. I for one only take a single micro USB in my pocket for my phone. So its would have Been nice to be able to charge both device with one charger. But I mean scull charge usually carry me all day. So I don't see it as a major problem right now.

Its actually 500mA not 500mV. Usb provides 5 volts at 500ma for usb 2.0 and that will be picked up to 900ma in usb 3.0. Even with this in mind it isn't the biggest problem with stoppinh usb charging in the xoom. The issue I believe is in the fact that the current charger is 12 volts and 1.5 amps. That's more than twice the volts at tripl the amperes.
Even beyond the amperage issue charging a battery that is set up to input from a 12 volt source with a 5 volts supply, even if it was possible with existing xoom hardware it would take forever!
I wish there was a way to have both options available for charging. Use the USB if you have no access to a AC adapter, albeit, a slower charge.
It seems that there's a false dichotomy here; the options aren't only trickle charge by usb and wall adapter with the proprietary connection. What about a wall charge via the usb port? I don't see why the usb port couldn't be used for the charge. I can trickle charge my n1 or I can plug it into an outlet, which charges the phone much faster. I'm sure the xoom could have been designed to suck in more power when conected to an outlet.
The only plus with the proprietary port is that we can charge and have the xoom connected to a computer or peripheral at the same time.
I've found a couple forums on this but no solutions. Can anyone confirm a working fast charge USB cable other than the stock LG 3' long one?

Thanks. But chargers are easy to find. What is difficult to find is a USB cable to work. You'll see in the thread I linked on the first post, lots of people are having challenges with finding USB cables to work even if a charger is well above 2 amps. Even using the stock LG charger, no USB cables seem to work except the one that came with the phone, to eliminate the "slow charge" icon and allow around 1500mA of current to be drawn from the charger like it should in a fast charge..
what cable are you using with your new charger? And do you get the slow charging icon?
I think it all boils down to the charging base... I have used the LG, various Htc and Samsung base units with all kinds of mini & micro USB cables without any issues... The base units are rated from 800mA~1.5 and have not had any slow charging issues... I've only experienced the slow charging when connected to the PC or some car chargers...

I used to run a 1.5' usb cable from monoprice and the GPS on my phone would discharge the battery faster than it could be charged. Now the phone charges so much faster.
I have yet to have a problem with any of the generic monoprice cables and wall charges I bought a couple years ago. Only time I get a slow charge notification is using my 1a car charger. My Optimus G and HTC One X chargers and cable work fine as well.
IT IS NOT THE CHARGER!!
It is something in the cable. And good luck finding one. If you use the included USB cable that came with the G2, then it will charge on ANY charger "normally" (fast charge). If you use ANY OTHER cable, it will slow charge.
I don't know what is in the cable or why it makes a difference, but none of my USB cords/chargers work unless I use the INCLUDED USB CABLE.
I had a thread on this already somewhere in the General Area I think. It REALLY sucks because I have TONS of chargers and cables. I have some at work, home office, bedside, 2 in my car, friends cars, etc. I DO use Wireless Charging at night and luckily the phone has a huge battery to last through the day.
There IS a problem here but my thread got ignored like, "I don't see a problem here, just use the included cable". Well yea if I stayed home all the time. My work makes me travel for work so I have to make sure I remove the 1 working cable and carry it with me EVERYWHERE. What a pain in the butt.
Has anyone tried on custom roms to see if perhaps it is something just on the stock software telling it to go Slo-Mo.
My Verizon non usb attachment cable charges fast. My OEM Spectrum cable does as well. My dual one amp car charger charges slow no matter the cable, and my works Motorola and Kyocera cable charges slow no matter the connection. I have a couple Samsung's I need to test. I do not own any generics. I have not tried other combos.

LG Spectrum cable does not work, slow charge, my fault.
However, the straight plug from my new Verizon car charger does work, the USB port also (ONLY with G2 cable so far[tested lg spectrum, Motorola, Samsung, and Kyocera. Older cables]).
Recap: So far ONLY Direct car charger or USB G2 cable has fast charged. Must be chipped or using some different wire combo?

Ok. I can confirm that the cable used for the Nexus 7 (2012) works.
Also, the original cable for the Samsung Skyrocket works.
Works meaning fast charge.
I can't gurantee that this is the cable, but my skyrocket cable does look like the top cable here:
http://www.ebay.com/bhp/samsung-galaxy-s-ii-skyrocket-usb-cable
(Charger looks like it too, but the charget won't fast charge G2)
Edit:
The Skyrocket was really picky about cables/chargers. If it didn't have the correct one, it would wakelock. Maybe there's something with the way it's wired that makes it good for the G2 as well.

Yeah, I'm not so sure about that. It may be the software in the phone that is causing the issue. I had to replace my car charger so I picked up a rocketfish 3.0 amp charger. When I originally used it, it was ridiculously fast, literally 30% in about 30 or so minutes.
Now, here's why I don't think it has anything to do with the charger cables. When I got my phone, I kept putting off doing the first update because I wasn't sure if I was going to root this phone. During this time, I got very good charging speeds from my rocketfish 3.0 amp car charger and many of my other rapid chargers. When I decided I wasn't going to root, I went ahead and downloaded the update. Now, unless I'm using the cable that came with the phone, I get the slow charging message with every single charger. I went from 30% in 30 to about 10% in 30 on my car charger.
I may need to pull out my tinfoil hat, but it would be a pretty huge coincidence that all my charging woes began with that update.
Yea something isn't right. I have a GNex, G2, Nexus 7 2012 and 2013. I always check for AC charging in Settings>Status. It will say AC or USB. When I got my Nexus 7s I replaced all of my chargers with fast chargers. For 2 years I've been fast charging. I got 3 different fast USB chargers on my desk, using the existing setup, Everything fast charges except the G2. If I use the included G2 cable, it will fast charge off all of them. The same with ALL of my home/office/car/travel chargers.
I can only get it to fast charge when I use the included USB cable.
Its something magical with that cable.

I haven't even unwrapped the charging base and usb cable that came with my G2, they still remain in the box. I have been using the charging bases from my Nexus 4, L9, Htc One X, Motorola Atrix and a GS3 through out my house and have mixed cables from god only knows where and all of them work. I get no slow charging from any combination. Even using mini usb cables with micro usb adapters attached and they all still work. I've checked all the output voltages and the lowest one is 800mA. Granted my D801 is rooted, but no custom rom as of yet.

Have you gotten an OTA update?
I'm on the Verizon model. The other guy here said he only started having problems after the Verizon OTA.
-sent from my LG G2 using XDA Premium 4
Here's my theory,
There are chips either in the battery, the transformer, or both. When the phone doesn't detect what's required, it gives a slow charge message and reduces the charge speed. I have had previous phones with batteries that had built in chips that I had to buy because the generic batteries without the chips wouldn't work as well. I haven't taken a good look at the battery, and the transformer seems abnormally large, when I get a chance and some spares, I'll probably take them apart.
My tinfoil hat is telling me that LG is trying to rope us into buying first-party accessories, but it may also be a way to regulate battery health. Having a non-removable battery, it may be a move by LG to extend the life of the battery as long as possible.
Also, I just rooted my phone and so far no change. I will try the car charger tomorrow.
No updates from Tmobile as of yet... I can only imagine the frustration though. You would think LG would have made charging the phone, regardless of the model more standard across the board.

800mA is a slow charge... You should average 1700mA. Our cable is five pinned (if that matters). I need grab the mA reader app again. Now we know there is kernel check for flux ect. I want to know if the cable is pre chipped as well for check and regulation, isn't too uncommon. I'm beginning to lean more on an over aggressive kernel check though or possibly a combo of kernel and certain chip model check. I just find it odd my straight Verizon car charger and only this cable is working for me. Gonna check car cable pins in the morning. Verizon here, OTA taken. Did not check before.
I could not find a solid answer on this.
I know that MHL 2.0 puts out 900ma but my question is, how well does the charge? Does it keep it powered and charging? I had issues where my MHL adapter didnt charge it at all. I am asking only about the official MHL adapter.
The official Samsung mhl? I have the Samsung and it does charge depending what u use. I can plug the usb right into my cable box and the charging sucks..If I plug it into the wall adapter it does ok.. basically it charges very slowly when plugged in streaming a movie..

I agree. I have the Samsung official one I tried other brands and did not work at all. It does not over-charge like what I expected of a car charger. One night I was low in power watching a movie and the phone died...but it was charging and I always use the wall charger. I had to let the phone get up some percentage before I could go back to the movie.
So Now I make sure I am above 50% but if watching a 90min movie say at 50% & charging thur the MHL I will be at between 35-45% when done. With the screen being on, on the phone I would call this good the screens burn a lot of juice.
For anyone doing what I wanted, connecting to their car pioneer radio with the most flexibility...I bought a PTV3000 from netgear, has worked with all my devices (Motorola and Samsung). I got it for 58 bux after tax at staples with a 10% off coupon. Is it the best for fast moving things? no, but I don't use it for that either! It's my GPS and music for trips. It is a bit laggy, but overall great experience.
PS: I also had the Wireless Hub and that worked great too, but only on Samsungs.
Is it both the charger brick and the USB cable that support fast charge or just the brick?
I ask because I want to use the longer USB cable from my Samsung Galaxy Tab S but somebody recently told me the cable also has to support fast charge. When connected, the phone says it is fast charging.
Can anybody confirm this?
Thank you.

I used my longer cable I got with my galaxy tab s, and it fast charged fine.
Technically the brick, the cable and where you're plugging it into all play a part. But it's actually only the brick that's fast charge certified.
Granted if you buy a cheap cable, then it might not work. I have several cables that are very thin, and didn't work with fast charging. But they were cheap.
I have numerous white Samsung cables I've used over the years, going back to the one I got with my galaxy S3, and all of them work with fast charging.
If it's a decent cable and not cheap, chances are it'll be fine.
If it says its fast charging, then it is

Ye thats the first thing I checked, but a few days ago someone on these forums suggested that even tho it says Fast charging, it does not fast charge with a "non-fast charging" cable. I guess he was making it up.
I'm looking at avoiding powerbricks in my house. I've been upgrading the outlets in my house to USB's simular to this: https://www.lowes.com/pd/Legrand-Radiant-15-Amp-Tamper-Resistant-Outlet-3-1-USB-White/50253183
would I still be able to charge my phone and if so how fast? This would be the pain reason why I don't get the 6t and end up with a pixel or something.
thanks.
I have a similar setup in my kitchen and had a 3T. You can definitely charge your phone using an outlet like that and USB A to USB C cable, but it will charge slower than if you were using the wall plug and cable that come in the box with the phone. In my understanding the fast charging through VOOC/Dash charging is enabled by the wall plug, which does the heavy lifting of converting the power. This approach is supposedly better for the long term battery life. It definitely keeps the phone cooler and running smoother if you use it while charging. That said, I doubt that charging through a non-OP charger is bad for the phone or battery. It will just take longer.
How much slower? I think I set this thread up wrong, Im sorry.
Sorry I don't have any metrics. I mostly used the charger that came with my 3T. I'd say if you want the phone mostly charged in a short amount of time you need to use the charger that comes with the phone. If you aren't going to be using it for a while you can use any other USB C cable or charger you have available.
