Phone struggling to charge.

Hello everybody. Recently, I had my phone go under a repair which involved opening up the entire phone just to replaces the mini usb port, which was detached from the phone and was trapped inside, losing its ability to charge.
Now, another problem has arisen. The phone has problems charging with wires compatible with its port. When I connect to it to charge via usb, it was plug-n-go, all good. For some unknown reason, it suddenly came under the issue that I need to shift the usb up,down, left, right, and slightly bend it the inside. Now, the original charger doesn't work because it broke, leaving the usb charger as the only option. I can't understand why my HTC Wizard is having this problem,and it's very frustrating. I paid sixty dollars for the repair on the USB, and it seems it hasn't done anything except reattatch it. Any suggestions?

Hey Infinity M,
By your description, it looks like the soldering is a bit loose, thus you have to shift the USB.
Have you tried with different chargers and cables?
If you wish (at your own risk), get a thin screwdriver or something like one, then apply a small force to all directions at the border of the Wizard's USB. Watch if it moves with any pressure, as that will indicate a loose solder.
Good luck, man!

Thank you for your sufficient reply. I have not tried a different cable, and I have checked the Wizard's USB. I'll have to try another cable to check if it works. Do you know where I can buy a charger for a cheap price. Thanks!
Edit: Heh, I realized you're the same person making that HTC Obsidian Case, I'd love to pay you for it lol.

That's a hard one. I would send you straight away to eBay, lol, but I guess you can take a look at some local stores near you. It doesn't need necessarily to be a Wizard's charger. In fact, any charger for a HTC device that uses the same battery will do (the Tytn's I guess). Or you can check the charger label and see if it meets these requirements:
INPUT: 100-240V~0.2A
OUTPUT: 5V, 1A (this one being the most important of all)

What i steh port behind the battery cover?

As the title states, what on earth is it for? Some are saying its for the car kit, some say it's a charging port and I think we're all lost. Sorry I can't get a picture because the HD2 IS my camera! Anyone care to shed some light on this matter? I'm looking into a diy wireless charging solution and if these 3 pins are battery connectors, then I can use this port on the back.
Cheers!

It's for use with in car hands free and GPS. You take the back cover off and just click the phone in and hey presto, it's all snug and secure.

Any possibility of charging through this port? A few pin out diagrams would be useful but maybe I'm just pushing it now. haha

most definitely there must be... since it does charge with the car kit it seems.
You should be ok by checking with a digital tester the voltage output from those metal contacts

Good idea. I'll give that a shot now. If all goes as planned, great! But next, to work out how to jam an inductive coil behind the cover!

You'll be lucky! I think, think, you can get some whereby you need to remove the battery and the cradle fits in it's place. I would Google it, but I am hungover and feeling lazy.

Haha! big night out I see!

Hmmm. Can't seem to find my multi meter. Anyone able to test if any of these connections have something to do with the battery terminals? At least until I can get my hands on a multi meter.

5.9 ft Power Cord

I saw this on another forum and didn't see any word about it here hope that it helps.

I purchased this yesterday. Not bad pricing for the manufacturer. Just didn't like paying ten for shipping.

yeah, that $10 killed it for me. I'll just continue using the cheap $2 extension cord.

This is nice and all, and thanks, but I wish there was a reliable third party 10-12 foot charge cable, so I can sit a LITTLE bit farther from the power outlet. Thanks though, may look into getting an extra.

That's exactly what I did because it was cheaper and quicker. I definitely could have crimped the cables better but I wasn't going for an award winning cable here. Still, everything works perfectly fine and I have a much longer cable.

So its just one single wire? I have heat shrink and sure i could do the same.Does it have to be that thick of wire? Some times you seen wires that are two.

two leads inside i'm sure. I'm planning on doing this as well.

So is if its 2 seperate wires and I only see one blue so how does that work?

If I were you I would not attempt this delicate procedure since you have obviously never opened up a wire casing, let alone splicing one together.

It has been some time since I've done something like this is true. I have all the things needed to do something like this but wanted to verify. Thank you for your wise knowledge in this matter. In will make sure I have an different way to change if I make a mistake. Also what made his choice in the gauge wire he used?

I bought one from PWR+ recently. Have only used it for a day now, but it appears much better than another one I bought a while ago, which in fact disintegrated rather quickly.
Sturdy build, longer cord than the OEM charger, plug fits better.
Search for "PWR+® AC ADAPTER CHARGER FOR ACER ICONIA A500-10S16U A500-10S61W A500-10S32U TAB" on e-bay.

I have the 6ft factory charger, after breaking the tip on the original one. It works fine but it's still a little too short. If I can get a new tip, I'll make a really long one out of the broken one.

silly ***ed cord
I know, right? What gives with the cheesy 18 inch power cord Acer sends out with their iconia?
I didnt know they made a longer cord till reading this thread. Seems any PSU that provides the amp and watt rating would work. (old laptop cords dont work since the business end doesn't have that round connector.
I agree with some others; the two buck extension cord is a value buy.
ten bucks for shipping? guess that is how they pad out their costs...

Wireless charging!

hey guys,
So i noticed 2 extra pins under the battery cover of my GN2 today! i looks like they are for wireless charging similar to what Samsung promised for the gs3. I don't really feel like waiting for the official wireless charging kit from Samsung so I'm going to attempt to make my own wireless charging back! I've seen videos like this before so i know it can be done! i have got the old inductive charger and back from my ancient palm pre so I'm going to give it a shot! just thought id spark up a bit of conversation about the topic and maybe learn a bit from some people who may already have done something similar!
I apologize in for the terrible grammar
thanks !

Isn't that for NFC? My original note had those and they matched up with the contact points on the battery cover and its nfc chip

As you can see in his pic the Note 2 has two sets of pins... One set (the upper pins) is for the NFC that lines up with the battery cover and the other set (next to the battery) is "most likely" for wireless charging because I did my own mod for the S3 and it works perfect but until someone does it we don't know for sure??

that's NFC

The whole mod cost me $18.00 on my S3 so that's how much it costs for everything... It's real simple too! I KNEW those bottom pins were for charging but some people just kept saying both sets of pins were for NFC which would be WRONG.... :highfive: Follow this thread and you can get all the stuff on Amazon... You will probably need some of the stronger magnets though which are another $10.00 for 100 of them on Ebay...
LINKY:http://forum.xda-developers.com/showthread.php?t=1877191 Thanks guys for getting to this!!

can anyone clarify:
which pin is + and -
what is the max current (at 5 volts?)
and other than getting the correct voltage, is there anything else that a wireless charging back-plate would need to do? (I am thinking of making a simple one with a LM7805 + a diode and a coil)

I'm waiting for the official Samsung one. I hope it does 2A wireless charging ! hehe.

magnetic fields only induce current when the field changes(think transformer). It's AC not DC.

How long does it take to fully charge the phone? Because the palm's wireless charging module's output current is far lower than the samsung one as far as i knows.

It's limited in the kernel to .5A, optimally 6.2 hours.

What current? I thought current referred to electrons flowing down a wire. It is wire less.

Mate. Wiki how a transformer works. Its basically 2 coils set next to each other. The coil in the dock has current flowing through it and this creates a magnetic field. This local magnetic field pushes the electrons around in the coil we have put in the back of our phones and tadaaa! Current. Electrmagnetism into Electromagnetic induction. So we dont want more than 0.5A in the case coil.
By the way see http://forum.xda-developers.com/showthread.php?t=1951493 for 2 common solutions to the mod (soldered and non-soldered) my non-soldered solution works a treat.

Dude, I am an electrical engineer. It's more complicated than that. Only changing magnetic fields generate electric fields that induce current in a wire. The current is AC. 0.5A makes no sense, to me.

Nexus 5X - Qi Wireless Hack Mod

neat mod, but seems that it still needs further testing since its so new. qi charging at the end of the video.

very interesting, hope to see a video on how they do it!

I have to believe it is something like the Tylt Vu. It has three coils and is quite tall.

This mod makes me happy as I wait for my N5X to be delivered but that theme just brings back a memory from the only time I've shedded a tear in a video game.
Sent from my SM-G920F

very interesting... Still really risky, you will have to void the warranty to do this and if you don't shield the heat or if the wire touches something wrong it could brick. Just be careful guys. Zsnaps is a safer alternative that makes charging simple. Wish they would ship already

not charger. but a receiver pad.

Why can't someone make a bumper case for the 5X that incorporates a Qi charging coil and plugs into the USB socket? I think there are auxiliary batteries for some phones like that. That would work for me.

Agreed. And (surprising to me) not everyone likes wireless charging. I hope the intersection of the two (and the 5x community) is big enough to warrant market attention.

I asked the poster ,xCubicle....
What's the large light grey patch on the inside of the back cover?
It can be seen in the ifixit teardown images at step 4.
Got the response...
"useless sticker. peeled it off."
I couldn't help but think back to the AMA
specifically the part "...Meanwhile, wireless charging adds z (thickness)..."
So what's the deal here with the blatant capability of qi wireless being designed into the rear case but the spec being deleted...?

It's because they did not want to give qi to the 5x and leave it out of the 6p because it has an aluminum body.

I'm pretty sure you hit the nail on the head here.

It wouldn't have been as bad if they'd just said that, but the bull****ting about thickness as an excuse is not cool.

after further testing with the mod. i am indeed able to charge wirelessly up to 100% from 0%. i measured the wireless charging current and it seems to range from 100-500ma charge rate. a typical charger ranges from 1000-2500ma charge rate.
regardless, its a working mod so far.
i need to refine the wiring to layout to make it a bit more appealing before i offer it as a modding service.

Awesome news. Looking forward to potentially doing this mod myself!

I bought this for my Nexus 7. Yep it is the largest one, you can even buy it from a Verizon store.

Charging time
Can anyone comment on the wireless charging time with the mod compared to the wireless charging time on the older Nexus 5 which had it built in?
In the same boat as many, where the lack of Qi has prevented me from upgrading

What will happen if wireless charging and USB Charging together?

Not even sure what happens now
To answer my own question form my last post. "Even the more expensive Qi modules appear to charge slower than the factory built in modules". Not sure what the reason for would be? Or people do not realize they are buying lower powered (yet more expensive) modules. Most posts I have seen refer to 500mAh modules
