[Q] wire a power supply to battery terminals?

I have a captivate with a broken USB port. No cable works, and it won't charge. However, other than that, it works fine. So I was going to make it an MP3 player, but of course, powering it is an issue.
So I was thinking that if there was some way to get a little power supply and wire it right to the battery contacts, it could just sit there running off wall power all the time.
Voltage isn't much of a problem, but does anybody know how to figure out the pad layout for the contacts?
Anybody done anything like this?
Thanks for any help.

get it fixed for like 35 buck link in my sig for connexion2005

Thanks for the info. I did google a few places, but most wanted 75-95 bucks to fix it, and that just wasn't worth it for my needs.

$35 in my sig. you should do it. I had to and it was well worth it

The desktop dock will charge the battery independently from the phone

There are a number of chargers available on Ebay that can charge the battery outside the phone. I think I paid about ten bucks and got one with an extra battery.

Yeah, that's what I'm currently using. I just wanted to have it permanently wired for power. But fixing the charging port seems to be the simplest solution.
One advantage of wiring it directly would be to avoid the pigtail hanging out the top of the phone, but I may use the samsung dock once I get the port fixed, and that eliminates that problem...
Thanks again. (Of course, the other problem is that I can't flash anything to the phone unless I can download and flash it from cwm, since usb connectivity is completely shot).

Possibly dead USB port

Arg.
So my otherwise adorable 1 year old somehow got his hands on my Captivate this weekend. When we finally caught him, he was chewing and slobbering on it pretty much right where the USB port is. After getting the phone back out of his grubby little hands, my wife and I took it completely apart and have had the whole works soaking in rice for a day or so.
When I put it back together, it booted just fine, and everything seems to be in working order. Except...when I plug a cable into the USB port, it doesn't charge, and it doesn't connect to my computer for storage mounting/flashing. This would be a bit of a problem.
I've checked for obstructions in the port itself and there don't seem to be any. I can get by for now without charging because my wife and I have the same phone (so we can periodically swap batteries...), but she's leaving town for two weeks at the end of this week. I really don't want to have to buy a new phone...so any ideas on fixing this would be greatly appreciated.

Once the USB port is gone its gone, you would need to get an external wall charger for it and a wifi file browser.
there might be some moister in it yet, but generally the captivates had issues with the USB port just flaking out like that. Its a common problem for this phone, and also has happened to mine.

Or you can just pay ~35$ to get it fixed, look in my sig. They are good!

Hmm...I didn't even realize that was an option. I'll be looking into that. Thanks!

They fixed mine and it works great. I would also order a new cable from them for like 7 bucks. It is all well worth it!

interesting, didnt know about that one either

Update:
It's apparently not *quite* as dead as I thought. It's still not recognizing my computer or telling me that it's charging...but apparently it is actually charging my battery. I plugged it into my computer just to see and left it. It never said that the phone is charging, but when I came back a few minutes later the battery meter had gone up, and it's still doing that fairly consistently.
That's at least good news for now. Even if the USB transfer is dead, I'm still OK as long as I can charge. As long as I don't have to use download mode...

That sounds like a bad cable, just buy one of those first, cheaper and easier to check!

It's nothing to do with the cable. We have four USB cables and two different car chargers. It's the same thing with all of them, and they all work perfectly on my wife's phone.

My first Captivate had a USB port go bad.. I tried 10 different cables and decided for some reason it was a ROM issue and got into download mode.. well let's just say I was buying another Captivate the next day.. lol
I did resurrect it by buying a Captivate with a broken screen on Ebay cheap. Combined the two and it's actually a later production and the GPS works good compared to hardly at all before. M yold screen and new guts.. Now I have a spare phone to try new Roms on without messing up my daily driver.. (Dark Knight 4 atm)
I see broke screen Captivates for $40-80 on Ebay regularly..

My wife also has a captivate with a dead USB port. So I went on amazon and searched for captivate batteries and external charger and found a package that came with 2 extended life batteries and the wall charger that charges one separatly from the phone while you use the other in the phine . Its made by Laza wireless and both batteries and charger was 15.99 and shipped free. Got it in two days and works great and was a whole lot cheaper than a phone.

Sorry to resurrect such an old thread but, I have had the same problem for months also caused by a toddler sucking on the phone and cables. I swap batteries daily. stock/1800/2430 mah. I am curious if anyone knows of a wireless charging option. I know my wii batteries are inductive and it is just the new battery and charger on a stock remote. is there an inductive charger and battery available for cappy? is wireless charging dangerous to the phone if it wasnt designed with it in mind? for that matter is anything available for anyother phones besides the lumia 920 and maybe nexus I think?

cheapest, best option is to get the USB port repaired by mobiletechvideos.com, imho.
I know of no induction solution for captivate that works without a good usb port.

I figured and also thought the Cappy wouldn't be a device supported by a new battery developer when there is so many newer ones out.
Thx

Looking for a power without battery cable

Don't know exactingly what its called but yea "power Bionic without battery cable" and would there be a way to mod/create one out of a regular cable.
thanks for the info

Are you talking about an inductive charger? You won't be able to use a standard cable for that, and would have to put a special case on your bionic.

Team Black Hat sells them periodically. Supposedly you just need to swap one pair of wires in a standard usb cable to make one, but I never looked too deeply into it.

If you want to try and make your own, that link will explain how.
We will have more available in a couple days, probably by Monday or Tuesday next week.

[answered]Not charging via pogo pins

My dock has been charging my phone perfectly for weeks, the other day I came in and plopped the phone on the dock and nothing.
I checked the pogo pins (of the dock) with a multimeter, they are working. I've tried different power sources for the dock as well (wall adapter, pc, other cables).
I've checked to make sure the pins are making contact with the phone, good solid contact.
I haven't changed anything on the phone recently, any suggestions?
The phone charges fine through USB.
[ANSWERED]
since i apparently posted this on the apple forums instead of xda, all the replies were "shoulda bought apple products"
so anyone having this problem, i solved it by reinstalling a nand backup. apparently it was a software issue. hopefully this saves you from the apple fanboys.

do you have original sony cradle? i had chinese replica and it did not work all times.

No, I was too impatient for it and got the goosewhite dock, besides I like the looks of it better tbh. The dock is putting out power, I don't get why it's not charging. its not a complex system at all.

Get the Sony one if you don't want the same issue occurring.
Sent from my C6603 using xda premium

why would changing the dock have anything to do with the problem? when voltage is applied to the pogo pins, the phone does not charge. how would changing the dock i use make a difference in that at all?
i would understand if the pogo pins were putting out less power or no power, but they put in exactly the amount of power going into the dock, they make good solid contact, i've check continuity and its making a solid connection...

Then take the dock apart and see if anything got loose

Because the one you've bought is rubbish!
I brought this as an alternative to the Sony DK26 because I was sick of opening the flap everytime I wanted to charge my phone. It does fit the Xperia Z and looks nice enough. It also activates the dock mode and the Xperia's smart connect function. This is why I gave it 1 star. HOWEVER, it outputs at 500mA as opposed to the 1800mA delivered by the Sony dock. This means it charges your phone incredibly slowly. I had my phone on the dock charging for 11 Hours and it managed to deliver a battery charge of just 51% which is ridiculous compared to the Sony charger which delivers a 100% charge in 2 hours.

I do not get why would anyone go for something cheaper and unreliable. Its like those iPhone users buying cheap non original cables to charge their iPhones, ended up causing the phone to blow up or messed up and blames it on Apple.
and yes you are the owner of the phone and you have the right to buy whatever 3rd party equipment for your phone, but dont expect it to work 100%.
Doesnt make sense if you ask me sir.
It is really hard to determine the main cause of this matter. It could be your phone: hardware or software (i doubt it is this one), or the 3rd party dock.
You tell me which one to throw and buy a new one.

Already told you why I bought it. There's nothing but stupidity in that review as docks do not put out power, they transfer it, the power supply puts out power. As for the amperage, it puts out what you put in. it will do [email protected] if you are stupid enough to put that through it... Assuming the wires don't burn. if you are going to base your assumptions on a review, at least choose one from someone knowledgeable. also, my dock never took 11 hours to charge, not that i ever bothered timing it but it sure as hell wasnt more than 4 hours (and thats giving an a good bit of a safety margin), i'd guess 2 hours 0-100 if i had to.
What I'm telling you is that the phone is not accepting the charge, not that the dock is messed up but the phone. And I wanted to know if anyone had similar issues or suggestions.
I'm glad you have insight on the matter and an opinion, however you are not trying to answer the question. I've already informed you the dock is intact and making a connection. I've checked the voltage of the xperia official charger at the cable at its end: 4v dc, the dock when hooked to that charger is 4v dc tested at the pins. I can put a larger amount through it, and any number of amps. A pogo dock is a very simple device, official or otherwise, the difference is mainly in price and design. The diy thread is a perfect example of that.
@LitoNi
I took it apart, nothing is loose. thanks

It's been answered, you've not bought an official product, that's the problem! Buy cheap unofficial batteries, expect issues, buy cheap replica SD Cards, expect issues, buy cheap unofficial chargers, expect issues, and looks like you can cheap docs to that list too.

XperienceD, please continue answering me with your infinite wisdom you learned from the internet. obviously you know everything about electronics.
btw fixed it, reinstalled my nand backup. software problem ftl.
didnt know this was an apple forum.

[Q] Issue with Charging

My OG Droid has been sitting in a drawer for a year or so because I can't charge it while it's on. I think that there is an issue with the micro usb port or something. When it started giving me issues, I got a new phone. I recently found it in the drawer and was wondering if anyone has had a similar issue and might know of a workaround. I have an extra battery and a charger for it, but the batteries die super quick. Anyone have any idea what I might be able to do to hack this so I can use it to mess around with?

could try
