Battery Charger

This may seem like a funny question...
But would there happen to be any chargers JUST for the battery? I have a feeling that the usb port in the phone is broken, and I just purchased a new battery. So, I would have no way to charger the battery, nor use the phone...therefore if I could find a battery charger I would be all set. OR, are there any broken/cheap mda's out there that only function to charge the battery(i.e broken screen/speaker/etc)

What do you mean you have a feeling the USB port is broken? You should know this when it's time for a charge. If your device is stll under warranty, try to get a replacement. Since the 8125 is no longer available, you may be able to get a 8525. The same thing happened to me, and I got a replacement after talking to a Cingular rep.

I'm assuming you have a 8125 since this is the Wizard forum, and you did not state what type of device in your thread...

Yes, there are chargers that you can get just for the battery, just check out ebay and I'm sure you'll find a few of them. You might also try your local phone store if it's a decent one that carrys lots of accessories, you might be able to find one there.

I have a tmobile MDA. The phone is out of warranty, and therefore I can't get a replacement. Unless I want to pay for it. The phone is completely dead, to the point where it will no longer turn on. I have read that once the battery is below a critical level, it will no longer accept a charge. I've also read that I would have to give it a small boost via a cut USB cord, to get it above that critical level.
I'm assuming the usb port is dead due to the fact that the orange light no longer turns on. This could be due to the battery being so low, OR the usb port is defective and not accepting a charge.
I'll certainly check ebay for a battery charger. Anything specific I should look for?

Based on what you're saying here, a battery only charger won't help. Where if you can remember did you read that a battery can't be recharged after reaching a critical level? I have read where it's good to periodically drain the battery for extended battery life. The orange light is just the charging indicator, and the battery itself has nothing to do with it. You can plug in the charging port without a battery, and a working device wil show an orange charging light. Your charging port has lost connection inside. Did you drop or abuse your device? Either stock up on batteries, get another device, or have the one you have now repaired.

I'll look and see if I can't find one on there for you and post a link. If I remember right, just searching for t-mobile mda should get you a few of them although you may have to search through a few pages to find one.
Here's one that I just found that has both a sync charger and a spare battery charger(what you're looking for) - http://cgi.ebay.com/USB-AC-BATTERY-...yZ146435QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
I know I've seen them that are just a spare battery charger without the sync and they were a lot cheaper but I didn't see any of them listed. I only went through a couple of pages though so I'm sure if you look a little harder than I did you can find them.

I found one on ebay. But I was able to jump start the battery w/ a cut USB cord, and now it's working fine.

Oh, I just read your post saying that your battery was completely dead. I can help you fix that one without cutting up a charger. All you need is a 9v battery and a couple of wires (wire bread ties will work if you don't have any wire handy).
Remove your battery from your phone and connect the 9v battery to it + to + and - to - for 10 seconds, disconnect it for 30 seconds and then repeat the process for a total of 10 times (connect fo 10 secs, disconnect for 30 secs). Then put the battery back in the phone and connect it to the charger again and charge it until it's full and then you should be good after that.

This method worked for me last week, I had the exact same issue and found the same fix somewhere on this forum, Great advice!

Wizard not powering on or charging

Hey folks,
I've been given a Wizard that isn't working, but I get to keep it if I can fix it . Just now the the problem is that it won't power on and I can't get it to charge. I don't have any of it's 'original' accessories (eg USB cable and charger). The USB cable I have is a 5-pin, which I believe is the correct one for this phone, but plugging it into my computer's USB port isn't having any effect, ie it isn't charging the phone. I have the charger for a Motorola Razr which has the same connector to plug into the phone, but when I try to charge it with this nothing is happening. I don't know if the phone is a G3 or a G4 and I don't know how to tell which it is. Can anyone give me some help here?

As the battery is fully discharged and dead,It won't charge through usb cable with pc,as it only provides a charge of 0.5 amp,it'll also not charge with a Motorolla charger,it can only be charged through a wall charger which is capable of giving output charge of 1.0 amp or you can try a 'Jump' start the battery.But if the battery is faulty,it won't charge at all,you'll have to get a new battery.

Thanks for the reply zabardast.
How would I go about jump starting the battery? I'd like to try it before I go out and buy a new one.

How to 'Jump start',read my post in this thread,hope you get it right and working.
http://forum.xda-developers.com/showthread.php?t=374108

if you're good with electricity and have a DMM or Fluke you can also check the resistance on the battery and use a steadysize capacitor to try and jump it. it might burn the battery but it doesn't work anyways so you don't have much to lose.
the capacitor size can be calculated using:
C(capacity) = 1/wR - where w is the network frequency.. wherever you live. (should be easy to find it. usually 50hz) and R is the value you see on the DMM.
buy that capacitor and charge it using either an AC source or another wizard battery (fully charged) even tho i doubt it would have enough power to charge the capacitor... and then you can jump your battery. an AC source would be a great option since you can set the frequency to the exact network frequency in your house.
Hope it helps..

Iv'e actually had similar problems, and I've oddly enough found that if I used the car charger it would turn it right on. I went to EVERY Cing/AT&T, T-Mobile store and used every charger and nothing. I work for Asurion so I see this happen all the time, Im wondering if I just replace the battery with the High-Capacity type if this problem will be over.
Also just a side not, but it only seems to happen when I leave it off the charger and it shuts off by itself

yep
i had the same problem. and as of today just bought a new battery! my love is fine and alive again!!! the battery is only around 10.00 and is well worth the money to have my babe back! do the same man! you WON'T be sorry ... and it's worth 10.00 not to have to mess with tryin to jump it.

how to charge htc 8125 with no original usb cable and(or) without orig. wall charger

hi there.
shortly-i have this phone with no orig. usb cable and with no wall charger. it was friend of mine phone actualy. given to me with dead battery (i am not sure but i have trouwn it away long time ago)
first I did was to wait until friends of mine from china had sent to me 2 batteries compitable with the phone. what i discovered is that a normal ordinar usb cable cant charge the phone's battery it only can connect to the pc.
second what i did is this: i found my old charger from a very old panasonic cell phone and had a try to make the charging process with the simply contacting corresponding pinouts of the battery to the +&- of this same charger (somehow i dissasembled the plug of that charger and it became more "comfortable" to get in touch to the pinouts of the specific cingular's battery)
that unordinar way i did discovered that i can charge these batteries even not sure how much appropriate that other brand wall charger is. It seems its pretty much the same as a power characteristics.
Meanwhile (as i dont use this phone) i had some free time to search the net and to have better idea about that strange unordinar power charging matter with that model of a phone. The situation is that i cant find a place nearby me to buy a cheap usb and wall charger and become using this nice device finaly.
And also i dont want to buy these cable things before clearly understand why this happens ..
I did try also to charge this phone with a HTC brand wall charger but no sucsess again cause it seems this wall charger is for other htc phone (even same mini usb plug and same characteristics)
What i need is to have answers by someone very informed about that matter and let me know what exactly is the specific power charging matter (need explanations i mean) with this phone. If sharing some good ideas about how to remake others usb cable or wall charger for geting it work along for me in such a case , i will appreciate this very much
thanks

charge
hi ! please forgive me for my bad english! in this case you can charge your phone in 1 way! you need to procure a motorola or any charger with same socket but attention the charger must have 6 volts and no less than 500 mAh(milli amps)! you cut the wires and one wire put on the + of the battery you will see the signs on the battery an one wire at the - no matter which one. and you need stay with the wires 3 - 4 minutes on the battery ! then you put the battery on the phone it will start and then you cand fully charge it with the usb cable ! good luckk ! i hope my inf will help you!

no
no it doesnt work that way.
what i need is the simple answer : what is so special into the pinouts of htc cingular 8125 wall charger?
thats what i need only. Then I might figure out how to proceed
Thanks anyway

I don't know if anyone else has had trouble doing what I have done, but I've got the Cingular 8125 (HTC Wizard 100), which is also known as the HTC 8125.
1. I bought a car charger at a convenience store for $6 that had the mini-USB plug. It worked like a charm. Never any problem there.
2. I also bought a standard USB to mini-USB cable from the local computer store, because I had lost mine, and it also worked fine for both synchronization and for charging.
3. I bought a second wall charger, buying a standard mini-USB wall charger sold pretty much everywhere cellular phone chargers are sold. It's a common charging port, and this generic worked for me as well.
I'd be interested to hear if anyone has had problems with these types of devices not properly charging the unit.
Even my USB cable for my portable USB hard drive will power my unit.
EDIT: About your problem with it not charging. I had that problem about a year ago, when my battery got extremely old. It wouldn't charge even with the original charger. I just needed a new battery. The batteries get old and stop taking a charge after a certain amount of use. How long this takes depends on how heavily the batteries are used. They, like car batteries, do not last forever.

I had this problem when I had my wiz too. The battery died and drained, and my phone refused to charge it. I took it to an AT&T service center, and they had no clue what the problem was, and they wanted to issue me a replacement (it was a G4, I had a G3, I wasn't about to fiddle with that at the time.) So I asked to borrow a demo device they had there to fix it. I charged my battery on their demo device no problem, got it up to 3%, and finished charging it through my USB cable in the car socket.
It appears to be a sort of one-in-every-few-or-so type condition, but I got hit with it.

seems like noone can tell me if something special inside the mini-USB plug.
i realy cant charge. Very nice device, but i cant make it charging up whit cables.
guys, from up there, say that nothing special about the charging cables, but i trust what i see not what i read.

Perhaps there is a problem with your USB port on the device? USB charging has standards, and all devices that need power from a USB port have the same power pin configuration. Otherwise, they can't call it a USB connection. It would have to be called a proprietary connection, and they would have to change the plug size/dimensions and pins.
If there isn't a problem with your battery (which is the most likely source of your problem), then it may be a loose connection on your USB connector. This happens with a number of devices.
If a sync cable connects to the PC but will not charge the battery, then you definitely have an unusual pin detachment of some sort, or a bad battery.

thanks again..
for pity i was writing a lot to make my recent post and finaly it desapeared cause my session was left.. its funny in some case, but now i just dont want to repeat all what was intended to be posted
i give only the link where you might see why i was assuming that this is a kind of a special matter here with that htc 8125 charging
//pinouts.ru/CellularPhones-A-N/razrv3_charger_pinout.shtml
so, any more help will be appreciated a lot
thanks

Hi - Too bad for the OP that asked questions but did not listen to this brilliant post.
I have confirmed that a variation of this method works perfectly! I have an old Cingular 8125 that I have been trying to charge for over a year using various USB chargers and NONE would charge the device.
The reason that this may happen is that the original charger has an output of 1 full amp which is much higher than most chargers. The voltage is the same but you need a charger that can handle such a strong current draw.
Nearly all USB chargers can only handle around 250milliamps - 500milliamps which is about half the power needed to breathe life into a fully discharged battery.
The best solution is to NEVER let the battery fully discharge.
Here are the details of what I did:
1. Find the best match charger of 5-6 DC Volts and ability to put out as close to one amp (1000mA) as possible. I chose an old Sanyo SCP-07ADT that is rated at DC 5.4V at 800mA. The plug can be any type, no need to be USB.
2. Cut the connector off the end of the cable and strip the outer black part up about an inch and then strip the positive and negative (red / black respectively) wires up about a millimeter, just enough to have bare metal ends to touch to a small area.
3. Take your battery out of the phone, look at the back of battery for the + and - marks which correlate to one of the metal connection points on your battery, this is where you will "touch" or "attach" the bare ends of the wires.
4. Plug the charger in making sure not to short your bare leads. Before you do this double check that the OUTPUT of your charger is indeed DC voltage so that you don't hurt yourself. You do not want AC output and it can be dangerous.
Then touch the bare end of the red wire to positive of battery, and black wire to negative terminal of your battery. I held them with my fingers while surfing the web for about five or ten minutes. I had no idea if anything was happening or not but it "felt" like the battery might have gotten just a bit warmer.
5. Unplug the home-made bare wire charger and put battery in your phone. Quickly attach a USB charger or just plug into a USB cable of your computer. I pushed it in and nothing happened at first but finally I heard the standard "bleep" when you plug a USB device in. I knew that I made progress because it never beeped before it took about 30 seconds and several "bleeps" of connecting/disconnecting from USB but eventually the charge light stayed on!
It's been about 30 minutes and I'm up to about 50% charge and been using the phone heavily while charging.
So, in summary... never let your battery discharge below 5% or you can only charge it with an OEM cable rated at 1amp (rare). IF you let it discharge to "dead" then charge for 5-10 minutes with the "wire" method and then charge normally!
Thanks to Dozzen for the original idea!!

Wizard that won't charge
When my Wizard/HTC 8125 goes dead my cure for the battery is to use a 9 volt charger with the wires stripped back also. But, my method is a bit different. I place a standard Christmas Tree light bulb (the newer small ones)in series with the charger wires. Observe the correct polarity. The battery is labeled + and - so that part is easy. By using the small light bulb you are doing 2 things. 1.You can see the slight glow from the bulb and know that proper connection is made. 2. You are limiting the charging current to the battery.
If you get really creative like I did you can solder a couple of small nails or in my case a set of red and black probes to the setup and the points on these nails/probes make for much easier connections. Note.... This method may take a few minutes longer but, is much easier on the battery.
In my experience once the battery is below a certain level NO charger that I plug in will work. I just purchased a used 8125 from eBay and brought it back to life most successfully with this method.

hy there my htc wizard battery whos dead so i charched with a cable with + and - the phone starts but when i try to connect to a usb or a adaptor it doesnt charge anymore it show me the charge icon on the baterry but it doesnt charge the usb works fine it's sync to my pc but it doesnt charge anymore... what sould i do?

So it seems no one touched on what really matters here.
A design flaw, in my opinion. The HTC Wizard cannot recharge via USB unless there is enough power to turn on. The reason is because it requires the OS to charge.
So, what many people already posted are very creative ways to charge your 8125. The easiest and cheapest way, in my opinion, is to use AA batteries.
1) Take two AA batteries and tape together so they are in series. Imagine it like this... [- AA battery #1 +][- AA battery #2 +]
2) Use two wires and tape one to each side of the AA's (one on the + side and another on the other battery's - side since the - of the first battery is connected to the + of the second).
--w-i-r-e--[- AA battery #1 +][- AA battery #2 +]--w-i-r-e--
3) Connect the positive (+) wire to the positive (+) side of the phone. By this I mean the 6 metal pieces that stick out to contact the phone battery. I did it by wrapping the wire around the top most one (or second top most, it's been over a year since I've done this.).
4) Connect the negative (-) wire to the negative (-) side of the phone. Again, bottom most or second bottom most (see #3).
5) Insert phone battery while the wires are still in and connected to the two AAs.
6) Let the power flow for 30 seconds or so and then try turning your phone on. This part is the important part because you cannot use a USB to mini-USB connected to your computer to charge the phone unless the operating system can function. Meaning, it needs to be turned on first.
7) Once the phone is on, plug in the mini-USB part and connect it to a computer. I'd recommend getting at least 5% battery before disconnecting the AAs, seeing as you need to be able to start up your phone long enough for the OS to boot. Once the OS boots, you can fully charge it through a normal USB to mini-USB connection on any computer.

old post but just wanted to say thanks. Used the wire to battery method and got phone turned on after 2 mins of holding wires to battery.

[Q] broken micro usb port (direct charging)

hi,
well i managed to snap my charging port inside my hd2 and well, i get nothing when my charger/usb plugged in... im wondering about directly charging the battery whilst being able to use the phone at the same time... ie having the charger contacts on the phone and battery at the same time... wondering if this is possible as i dont want to damage the battery/device...
also what would i need to hook to each contact? i know positive n negative poles but is what the middle contact??
any help with this would b much aprieciated... thanks
luke
p.s i couldnt see anything that would help me in the other forums i looked at

Yuor best bet is to buy a 2nd battery and a battery charger from ebay then use 1 battery whilst the other charges.
Its not to expensive to repair, if thats the only fault

i see ur from england too so do u know any cheap places that can repair this fault? links if possible... thanks

any joy? I found the following two websites but am now weighing up my options.
htcphonerepairs.co.uk/HTC-HD-2/Charger-Port-HD2.html
simtekworld.co.uk/index.php?route=product/product&product_id=529

I have a similar problem. Don't know how or why but for some reason it suddenly stopped charging on Friday night. £50 to get it fixed is a bit excessive.
I wonder if a battery charger might be a better option?
EDIT: the answer to my own question (so far, at least) is "YES". Bought a cheap charger and battery off ebay and both are working well (touch wood). It's a pain in the butt having to change battery and not being able to charge it in my car but it's also quite useful having 2 batteries.

Asus Padfone 2 (A68) and its battery + back cover

Hei all
After 3 good years of using my phone it sadly "died". 1 of those micro usb pins broke off and another one bended.
At the moment I can't really fix the micro usb port (missing the tools for it at the moment) and repairing it costs almost $100 (usd). I could buy the micro usb dock part myself buuuut....
So I went ahead to tear the back cover off and took out the battery to charge it directly. So far so good. No problem at all actually (of what I know of)
Now, the battery port has 4 holes: ID - P (minus) - TH - P (plus).
What is ID and TH? I am guessing the ID gives out a number, whereas the TH is a corresponding value to it, or perhaps just the temperature?
I am thinking of using my arduino board to make something fancy. But perhaps it isn't necessary? I don't know if I can just keep charging the battery all night long with a 5V - 1A / 2.1A charger?
Moreover, found something strange on my back cover. It has a copper plate on it? Was thinking it might be an antenna or something, but even without it I got WiFi, 4G, 3G and 2G. Anyone have an idea?
Tried to post some images, but I ain't allowed to do so since I am new here (or I am using this forum wrong)
However, if u search on "asus padfone 2 battery" on Google, then it should show u the battery port and the back cover.
Thank you all. Sorry if I am posting the wrong place.

ID Ibelieve is similar to BSI. It is connected with the GND through a resistor and helps the phone to identify what type of bettery is installed.
TH is probably the thermistor for identifying that temperature is OK.
