***having problems with tf not turning on or faulty charger? Read this

So im seen alot of q's asked about "epad wont turn on" or "charger broke"
Just to let people no 9 times out of ten when you tf wont turn on people tend to think its finished and say there good byes. But a member here has said that theres a problem with the cargers and that putting it in a zip tie bag and putting it into the freezer for 30mins will help.. supposedly the boxy part of the charger has heat sensers and there reading the wrong temperatures so thats the idea of the freezer..
Some user said this helped there heat issue too.
*make sure it a zip tie bag/air tight bag to keep moisture out..
If people whos pad still wont turn on plug it into a laptop/computer to allow a slow charge for approximately 3 hrs and see results
Last resort is to buy a new charger with specifications of output values of 15v/5v
Charging at 1.2A/2A
I write this because i was afraid it would happen me at some stage so i did the searching so you dont have too

The answer is simple. You've paid good money for it.....RMA the charger for one that works.

Even people whogot replacement chargers were complaining

As are those who havent even sent it off yet......

True. Hae any of you had this prob

Yeah I had the problem once with the charger overheating itself while I was charging my phone off the USB in the keyboard. It hasn't done it since but it's nice to know that it's a "known issue"

Is it ok for you now

The question should be.....
What is classed as overheating?

This has happened to me in the past, and its actually a really simple problem.
More often than not, melted charger connectors are a direct result from charging a device like this with the connector loose, crooked, or not fully inserted.
Our transformers require bit more power than a standard USB connector can provide. As such, the charger connector has a redundant pins for power, to spread the current flow over more than one contact point. This reduces the current flowing though each individual tiny contact point, which is supplied by a tiny wire, and thus keeps the temperature in check. If one contact isn't able to make connection due to a loose connector, crooked or incomplete insertion, more current has to flow through the other contact points which basically begins to overheat.
This problem isn't just related to chargers and things like that. Any devices which you contact points and flow a reasonable amount of current can do this. I've had it happen to a friend who didn't properly seat the DIMMs on his motherboard, and basically overheated some power leads on his DIMM sockets:

nice! I had the same problem, my TF was not charging anymore. I took the charger out of the wall-outlet and let it lie on the ground for a whole day. The day after that one I tried the charger again and it worked again!
Thanks for this nice and helpful information!

This actually falls more under general and useful information than Q&A, so I am moving this to the correct area. Thanks OP for writing this.

Nexus 4 Wireless Charging Case

Does anyone know if the wireless charging will work with any case on the phone? Or does this feature require no case to function with the charging orb that Google demonstrated in the video.

Well it probably depends on the size, but I presume it won't work for most if not all cases, since proximity is pretty key for it, not only for holding it in place (in case of the official accessory) but also for charging.

I figured it probably would not work. I was going to purchase this phone for my gf, but she is very clumsy and absolutely needs a case.

Do you think that a simple TPU case would affect the wireless charging?

It shouldn't affect the wireless charging of the phone. Something that's multi-layered like the Otterbox Defender might, but that may be more a problem with the case being too thick to allow the magnetic base to hold the phone in place, rather than the charging current not being able to get through. And remember, you can still charge it via the included USB cord and plug (although I'd rather use the wireless charging myself, just because I've never had that on a phone before). :good:

somewhat off topic, but it applies to cases. android beam requires two devices to touch, so will android beam still work even with a case on the phone?

It's not magnets that hold its in place; its just the rubber grip

NFC has a further range than wireless charging.

Everyone is saying the magnet will hold it in place...It might not be the case with Google Nexus 4 inductive charging orb. Matías Duarte mentioned how cool it was that you got inductive charging and the rubber on the orb which made the back glass stay put....

My review on this product is basically this.....
This product is amazing in every way it's described. Small, portable, lightweight, lots of energy, and can charge anything.
It comes with 2 ports to charge (can be used at the same time), and 1 port to charge the actual battery.
Can charge my iPhone more than 6 times....I have not been able to test it efficiently, but it works, and it works well!
How to describe this product....
Think of an iPhone 4 in a Otterbox. Now imagine it was a bit longer like an iPhone5. Now imagine that it looks like an iPhone, yet there isn't really a screen, it's just for looks. Now what you do is you put this charger in your pocket with your phone when it's getting low (or in the car, in a bag, purse, whatever), and than you instantly have POWER IN YOUR PANTS.
I've been questioned....why do you have a wire coming out of your pants? How are you charging your phone while walking around? What type of magic is this?
On a more serious note...everyone phone dies...everyone wishes they could charge their phone while moving, and they also wish their phones would never die. This device does that and more.
It's programmed to charge iPhones and Androids faster than normal.
It comes with a ton of connectors to charge tablets, all phones, laptops, and basically anything I can think of.
for $40...it's a steal. Buy it, you'll love it. Thank me Later ♥
My review on Amazon is very basic, and lists the only two flaws I saw....
1) The iPhone connector will unattach itself from the provided cord that comes with the device. I think the same applies for Androids, and tablets. I suggest using the standard cord your device comes with to connect to the external battery.
2) there's a lot of important attachments that come in this very small bag, and all the pieces are very small. None of them are really needed besides the USB cord to charge the battery, but I wouldn't want to lose them, and yet they are so small...I likely will. Wish there was a small zipper in the protective pouch it comes in.
Conclusion:
★★★★★/★★★★★ (A universal product that should be owned by everyone)
Cost: $25-$40...I suggest buying the largest one, simply because it's an amazing deal. I bought it for $50 not too long ago, and it can be a life saver. (Think about the shows where you get lost in the woods, and your phone dies) ^_^
Edit: basically changed my review on amazon to this. Hope that's alright with you guys.

where is the link for this thing or even a name for it to buy? i am not seeing it. sorry if i missed something.

My apologies, I seem to have forgotten to place both! It's made by Anker, or can be found at iAnker.com, or this direct link to Amazon. http://www.amazon.com/gp/product/B009USAJCC/ref=cm_cr_ryp_prod_ttl_hst_61
Sorry about that!

[DIY] Mobile Charging Dockinstation

Hi there, thought i might post another little Mod that came into my mind
We all know that the Xperia-Z ist not quite an endurance runner when it comes to Battery-Life and i guess most here will most-likely have a power-bank with them, just in case.
Problem with that is, the o-rings are prone to damage due to opening the flaps all over again.
This is most-likely also a main-reason for water-damaged devices, you know it, i know it, and Sony knows that too.
So lets see what we can do to that dockingstation, so that we get a mobile Power-bank Dock.
Its actually plain simple, you simply get yourself a so called "EasyAcc 3000mah U-Bright"-Powerbank, this Powerbank fits easily centered unto the Back of the Dockingstation without being distinguishable looking at it from the front side, and if you dont know the Dockingstation even sideways.
The Dimensions:
Topside of the Sony Dock : 14,4cm x 3cm
Easyacc 3000mah U-Bright : 10,7cm x 2,2cm
A picture of the Easyacc:

}
which would basically go behind the XperiaZ, and look like this Illustration:
The way you fix it in place would be really up to you, probably glued, or by using neodym-magnets, or probably even some Velcro or zip-ties.
Other than that you just really need a really short usb/-to/microusb-cable that goes from the Power-bank to the Micro-USB-Port
Hope this probably is useful for one or another!
Thanks.

That's actually not a bad idea!

Does anyone know what the voltage/current specs of the dock that connects via the 2 connections on the left side?

Do you mean polarity or really only the specs e.g. Voltage/Amps? The dock itself has an output of 5V/1,8A which is kinda funny as the default Sony-charger is rated 5V/1,5A
The mentioned Easyacc Powerbank outputs up to 5V/2,1A without (verified) getting hot.
Hope this might help

Apparently, the top contact when holding the phone is +.
See this post that states that + is the left pin when looking at the dock from the front.

If you are holding your phone horizontal with the connectors facing down (like you would put it in the dock), well then:
LEFT-> POSITIV
RIGHT-> Is negative.
Its actually even marked on the Dockingstation itself, in case you have the Dockingstation
See:
Hope this helps

Or you may consider using a power jacket, see: http://shop.brando.com/Power-Jacket-for-Sony-Xperia-Z-with-Cover-4200mAh_p09745c1512d003.html

Nice!
I had something similiar for my SGS3 but was missing something alike for the Xperia-Z.
Well i now did the modification mentioned above and iam good actually
Eventually get a power-case later on, although i kinda like the Xperia-Z as it is (thin as hell )
Thank you anyways for mentioning it, probably a better alternative to other Users

Z3C wireless charging achieved

Hey all,
I got this idea from someone else here, but I couldnt find the thread again to post this there.
My wife wanted a tough case, but she didn't want to have to use the USB port to charge. She had read, and she felt that the flap over the USB was too fragile.
So I decided to mod her Qi Charging.
We got her this case:
(too new can't post links)
and I got these things for the mod:
(too new can't post links)
I used a small piece of card paper (that came with the charger) I measured and drew out the design on the card, then I used the copper tape to make the contacts. I used two unbroken stips.
I used two small rolled up bits of copper tape to push the points out a little.
then I cut the wire off the charger and peeled back the shielding.
It turns out that there is some unshielded copper right under the thick part of the wire.
I did two very basic solders right to the tape, lined it up in the case and presto! Qi charging.
I did all the copper runs under the charger to prevent interference.
See pics for more detail.
If you have any questions I would be happy to help.
Sorry about the size of the photos.

What are the charge times like?
Also you can post links by putting a space before the .com i am pretty sure, doesnt make it a hyperlink though.

Just finished today so I can't say much about the charge times. The multi-meter I used was showing about 5-7 watts so I would guess that charging time should be about the same too a little slower than standard USB.
Here are the links with the space before the ".com"

don't be fooled by the listing the copper tape does NOT have Conductive Adhesive... at least not good enough to trust.

Very interesting. I didn't thought that the module could be so slim you can probably put it between your case and the phone without changing the thickness.
My rear glass is already broken, maybe I'll think about an internal soldering.

seems better to avoid interferences.

Simple.
Technical details of that QI receiver:
Output: 5V /500mA

Z3C Battery is 2600mAh.
Therefore you can say, that a full charge takes a bit more than 5 hours.

I'm looking forward to trying this. However, I don't understand one thing: how are the contacts that match up to the magnetic thing on the side of the phone connected to the wireless charger receiver? Do the two long strips of copper under the receiver connect up to the two short strips that make contact with the phone?

This is very nice, gotta try it sometime! Also, what case are you using?

Did it too, thanks for the thread.
My back glass was already broken so I had nothing to loose.
I installed the devilcase aluminum bump and the leather back they gave is pretty convenient to hide the glass.
I do not think you can achieve that with a pristine glass because the result is very slightly cambered, I don't notice it on a daily basis.
Here are the pics :

Waterproofness?
VERY NICE, been looking for something like this!
my question is how this fairs in waterproofness. is the QI receiver module waterproof?
