I recently bought this cable here: http://www.ebay.com/itm/20095042399...eName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
It wasn't untill now when I got it that I saw that it said in the description that it charged slower, but why? It shouldn't make any difference? Is it higher resistance?
It has nothing to do with length, but rather with them using thin wires designed for PC usb port. USB port on your laptop or computer is designed for a max 500mA output current. A lot of manufactures make cables for that spec, intended for data transfer from your computer. Others make fancy noodle shaped cables and use thin wires in there as well. New phones like Note 2/3 use 2A at full speed charging. More current - thicker wire. You need something like 24AWG thickness, and hardly anybody company selling usb cables advertise that. But you can get it from monoprice.com - just search for 24AWG. Those can handle up to 3A with a derating down to 2A. In general, thinner wires - more resistance, higher heat and loss, slower charging speed.

Okay then! Then a flat slim cable shouldn't be any good for charging at all.
Gonna order this instead: http://www.ebay.com/itm/PortaPow-Hi...ories_MobilePhoneChargers&hash=item4ac6919243

Perfect choice
I usually get monoprice cables: http://www.monoprice.com/products/search.asp?keyword=24AWG+usb but not sure if its available for UK delivery.
i think longer or shorter the charger cable did not make different change
at my experience it's about the original of the charger.i mean original for similiar phone

i have a PALM original charger for Pre with a original cable which work fine but the charger could not charge my Pre when i use another cable bought from ebay.
the cable is the problem.
i dont think so
Weird (as in: this should not happen by any rational explanation).
I do bought a longer flat cable to use the phone at night while charging.
I sometimes use it to charge during the day.
And I "feel" that charging takes roughly the same BUT the batter drains faster with the flat cable.
I know I know.. that probably is just my imagination
I have a Xperia Z1 and I was wondering if it is equipped with any functions that enables wireless charging (QI-enabled something)?
Tried googling but found no results other than some news on Xperia Z..
On the other hand, if Xperia Z1 does have it, is it possible to buy any wireless charging pad from ebay and charge it?
Don't know about it,too, but I dug into that tech a while ago in orderto know about pros and cons.
I have to admit, it's a convenient technology to just lay your mobile onto that charger and get it charged.
But there are two big disadvantages from my point of view:
Low efficiency - the induction tech used has a small efficiency, so there's a big loss of energy
Low charging power - the charging rate that is possible with the current tech is rather low, it takes AGES to have your phone fully charged, and I even read about people not getting any extra fuel because they used the phone during charge.
Personally speaking I like the magnetic charger plug for our phone a lot more, because it has hardly any loss and just takes a second to attach it, needing no closing of flaps upon removing.
Just my 2 cent

I have a n4 as well. Charge time is marginally longer/slower. The info you have read is incorrect based upon my and other users that have used wireless charging.

Thanks guys. I do own the magnetic cable (dismantle it for the cable), however it is a nuisance that the magnetic cable only works with the charger adaptor and not with the PC..
Been trying to find alternative ways to get my phone charged other than opening the flaps and I thought wireless charging may be a better idea

Nope. Mine is stock. infact magnetic charger seems to charger at a faster rate for me from Laptop
I have 2 of the magnetic cables: one is original from the sony DK-31 dock and the other from japan. Although the both look identical to one another, they function differently.
The original one doesn't charge from a laptop and has to be used with an adapter
The generic one charges from a laptop and can be used with an adapter, however in a laptop it charges significantly slower. Has to charge all night and it still won't be a complete full charge in the morning - it will be close to full.
1.) The Z1 does not have any sort of wireless charging built in.
2.) The Z1 will charge via PC USB connection, however the output of the USB cable varies based on the standard.
** USB 2.0 can charge at a rate of up to 750mAh with concurrent data transmission. Without data, the charge rate maxes out at 5A at 5V.
** USB 3.0 can charge at a rate of up to 900mAh with concurrent data transmission. Without data, the charge rate maxes out at 5A at 5V.
** USB 3.1 can charge at a rate of up to 900mAh with concurrent data transmission. Without data, the charge rate maxes out at 2A at 5V and up to 5A at 12V or 20V.
3.) Qi wireless chargers are slower than wall chargers as well. A typical Qi wireless charger transmits power at a rate of 750mAh at 5V.
To put this all in perspective, the standard wall charger that comes with the Z1 charges over USB 2.0 at a rate of 1.5Ah at 5V.
A PC USB connection will typically be 50% slower at charging than the stock wall charger for the Z1.
Thanks all for the reply. Yup, my cable is inded the one from the Sony Charging Dock and hence it does not seems to be working with the computers unless it is paired with the adaptors.
At least now I know that Xperia Z1 does not comes with wireless modules.. Keep hoping that it may have.

So back to QI Charging...
Is there already any Case out there for the Z1?

As we all know, the new Zenfone 2 is missing wireless charging capabilities, however there are multiple solutions to enable wireless charging on basically any phone.
Example is http://www.amazon.com/BEZALEL®-Wire..._1_4?s=wireless&ie=UTF8&qid=1432149451&sr=1-4
It is a cover with a Qi receiver built in, which connects to the charging port and it also provides an independent micro usb port as a part of the case.
The absence of wireless charging in Zenfone 2 is a deal breaker for me ( don't judge) and as soon as an appropriate case is available, I'll get it and the phone as well.
Please post your findings here.
Would love to use wireless charging but using a cover like the one posted is out of question.
I love the slim form and feel of this phone. so i will have to live without QI and other solutions.
This will occupy the mUSB port but would probably be the best current solution.

That's pretty cool. I like wireless charging because I'd rather not wear out my micro usb...but that setup kinda marries you to wireless charging all the time. I'd have to rig up wireless charging in the car and at work...not just at home. You use something like that?

Not sure if I'm going to stick with the ZF2, so I haven't gone out and done all that yet but qi adapters are pretty cheap now for both home and car. How effective some of the car ones are though are another story. iOttie has two models out now that look promising for the car.
There may also be the possibility of placing those adapters into a separate case just meant for wireless charging... remove the case if you need the mUSB port.]
Or... if they do release new back covers... get one that you install the qi adapter in and then one that you won't have the qi adapter in.
WHYYYYYYYYY
Why did Asus decide not to include the qi pins in the back ((((((((((((((((((((((((((((((((((((((((((((
>_<
what to do :'(
Here's a teardown: http://www.myfixguide.com/manual/asus-zenfone-2-teardown/
You could solder the DigiYes posted earlier (http://www.amazon.com/gp/product/B00HI8JYFE) onto the usb board. Or you could probably just jam the wires into the connector for a non-permanent solution. The pictures of the DigiYes are a little conflicting, but if it does have leads for the data pins, you'd be best off omitting them (you'll be limited to 500ma qi charging).
This is of course assuming there's enough space to wedge the DigiYes between the back cover and phone.

Which goes back to my point. Why did Asus purposdely omit to include QI/wireless charging pins on the back? It would had cost them hardly anything extra at all, and users could just have changed back cover to get wireless charging...
That one http://www.amazon.com/BLUBOON-Unive...2630&sr=8-2&keywords=qi+wireless+charger+1000 is 1000mA, if it does make a difference. But a case integrated receiver would be much better solution, if ever.

I bought that model. I have a Qi charger (used with a Nexus 5) hooked up to a 2A USB Adapter, and it barely charges the Zenfone. I do not recommend. Maybe a 2A receiver would work better.
It's ridiculous.... why did asus decide not to offer a wireless charging solution similar to the previous samsung galaxies/lg.
Have the pins for charging on the back, and let the user change the case to a qi receiver case or add a qi receiver pad inside. this is honestly the only thing that disappoints on this phone (((((((((((((

I just received mine and there is enough space in the back cover for the receiver to fit in, albeit with a small bulge. It does show my phone as charging even when just held up to my Moto 360 cradle; whether or not it's charging, however, I have no idea.

Thanks for trying. Did you actually solder or just plug it in the usb port? If you plugged it in the usb port, does the cover close without damaging the cable?
I'm asking because if that works, we could potentially design a slightly thicker but hollow back case that could hold NFC and the wireless receive without unnatural bulges.

It closes fine but there is a bulge and the cover is left slightly open.

Yeah I judge, wireless charging its just another feature. A small battery, a slow processor or low memory now that's a real deal-breaker since your phone wont last a day, apps will run like hell and you will always have to micromanage just for things to run properly.
I'm way more pissed off at this phone not having a removable battery, not just because its a real deal-breaker during travel where I will be forced to lug around one of those brickish power banks but because Li-ION batteries have the lifespan of a mosquito. I already had 2 phones like that and the result was always a massive pain in the ass to deal with.
I rather buy a case with an extra battery than this thing
Three pins USB Board?
Hi there
Maybe some one knows, what are those three pins on the USB board, that are accessible without disassembly phone?? That should be connectors to charging instead of usb socket?
I have a qi charger built into my car. I do not like aftermarket charger added to the phone. So this is a deal breaker for me and will not consider any phones without buildin qi charger.
Looking to buy this phone and own a quick charging card like this. Is it possible to slip the card under the back cover (without a case) or will it cause it to bulge in too unsightly a manner?

It can but causes a gap near the usb port that I could not close. I would've run it inside if it didn't do that.

Is it possible for the Nexus 7 to burn out chargers and cables? I've never known of a device to do this but my daughter's tablet has burned through at least chargers and cables in about the past six months. Each time the charger stops working on her tablet, it also no longer chargers any other Android device. I'm not quite sure what's going on here.

A permanent N7 fault can damage poorly designed chargers but not cables. As the problem is intermittent and both cables and chargers fail, it is most likely that N7 is used while being charged. Constant bending and twisting results in a cable short circuit which also damages the charger.
Might also be a short in the mini USB connector on the tablet.
You might want to try wireless charging and avoid using the port entirely.

It is actually a micro USB connector - what could be occasionally shorting there? But more importantly, is it possible for a short in the connector to repeatedly burn out USB cables (the OP's question)?
Let's check it out. I experimented on the weakest USB cable I could find - from a wired mouse, which is very thin because normally it needs to carry only a few mA of power supply current. I cut a single wire strand from the red, power, multi-strand cable (#1) and connected it to a regulated 3A power supply (#2). At 2A it was slightly warm, at 3A it was warm (#3). I suppose it would burn out at 5A and let's assume that 2A is the max safe current. As the red wire has 7 strands, then the max safe current is 14A and projected burn out current is 35A.
The 2m long cable has power path resistance of around 1ohm, so the max possible current from a 5V source is only 5A - well below the safe limit. A 1m long cable, shorted at the N7 USB connector could deliver max 10A - still below the safe, really conservative 14A cable limit. And we are talking about a lousy USB cable from a wired mouse - you can double the limits for quality USB power cables.
Can you see the implications? It does not matter how powerful the charger is because the cable's internal resistance prevents it from burning out - EVER (@5V of course).
Can you imagine what 10A current could do to a shorted N7 connector? The heat and smoke would surely be reported by the OP.
Finally, the original N7 charger delivers below 2A and most cheap replacements below 1A anyway.

Actually, the OP's question was "Is it possible for the Nexus 7 to burn out chargers and cables?"
Your analysis of the heating of USB cables, while interesting, isn't really applicable here. I'm betting that it's the chargers that are being overloaded and burned out. I'm also betting that the connector on the tablet is damaged and might be damaging the connector of any cable pushed into it.

I had this exact problem with a Lenovo tablet. The pins on the connector got bent out of shape and burned up several chargers until I discovered it. I messed up the connectors on a few cables as well.
That's why I specifically searched for and purchased a tablet that offers wireless charging capability. Those Micro USB connectors are quite fragile and easy to break. The less use they get, the better.
I've charged my nexus 7 wirelessly since day one. Wireless chargers can be found for cheap, certainly cheaper than the combined cost of your burned out cables.
In my two years of owning the tablet, I've physically plugged it in maybe three times. Usually if I'm traveling and didn't feel like packing the wireless charger and opted to just use my phone charger instead.
Hi everyone. My phone shows in the notifications a message about wireless charging but my phone is not conected.
I changed the battery and the wireless charging flex, but the problem is still there.
Any recommendation? you think it's logic board failure?
Attached screenshot.
Thak you very much, and sorry for my english.
Clear system cache.
Hard reboot.
Try in safe mode.
Is the wireless charger compatible and working, no case?
Firmware may have been corrupted, reflash to same rom. Otherwise a defective coil, cable or mobo.
Or just charge normally; it's better for the battery and Samsung C ports are generally extremely durable, cheap to replace. This one on my heavy used N10+ has close to 2k cycles on it, still tight with no issues. Nothing like the old micro jack crap. Still using the original Samsung cable and 25w brick. Dirt cheap and charges fast up to 80%. Li's love frequent midrange power cycling 40-80%. Less heat generated then wireless which is better for the battery.
