Hi all
Am repairing a Sm-t805 and have found that I only get 0.27 A at 5V when charging. This is no matter what charger or cable I use. So naturally it takes a long time to charge.
Questions is this. Is it a failing battery or a dodgy USB port?
I could replace both but really want to find out which is the offending component.
FYI I have cleaned out the usb port.
Any suggestions please?
Thanks in advance.

Hi,
Just purchased a cradle for the universal which has a USB and an AC adapter connection.
The USB works fine for charging the Universal.
The AC Adapter connection on the other hand doesn't charge the PDA at all.
I thought I remember reading something concerning a fix for this but can't seem to find the post for it.
Any body got the solution for it or do I have a faulty cradle?
Thanks.
I would change usb cable

Did you ever find a solution to this?, I have the desktop charger jobby. The grey one that looks like a docking station. It has an ac adapter and a usb out on it .. but like you the charger doesn't seem to work.
p.s its the one with the stylus that stands up straight at the back.
Nope.....
Never found a solution for it.

Does your original jasjar/xda exec charger work? mine doesn't.. only my 5v dc 550ma motorola charger works ... oh and the usb direct cable works..
Does you pda charge while sat in the cradle with just the usb attached?
Here's what I have working:
FYI, I have the Qtek 9000.
Original Power Charger - working
Aftermarket Car Adapter charger from Proclip - working
Aftermarket Desktop Charger (AC powered) - NOT working
Aftermarket Desktop USB plug - working
Aftermarket USB cables - working (at least the ones I've tried = 3)
Joe,
I remember reading that you should be careful of what you plug in to power up your HTC-Universal because the voltage needs to be regulated.
Also, don't even go buy those Alkaline battery powered travel charger - they don't work. I even tried with a 9V Altoid Tin Battery Charger (with the required 5V USB regulator) and it didn't work.
I just gave up and carry 2 batteries with me. Planning on getting a bigger battery later on.
Hope that helps.

Thanks for the reply,
Just checked on the web and the moto charger is regulated so it should be fine to use, I was thinking that my original charger may be buggered but because my new desktop charger doesn't work either I don't know what it could be. I'll need to try my cradle with just the usb attached tonight and see if it charges... if it does thats ok .. I can live with that.
My Cradle has a built in usb cable for the pc and a separate dc in socket for the wall adapter so unless it switches between the two i'm thinking that maybe the pins for charging are hardwired to the wall adapter and the data to the pc so it will only charge from the wall and not from the pc..
Maybe I shouldn't have bought such a cheap one
Joe,
I believe I might have the same cradle as you do.
I've open up the cradle to see how the connection is soldered and the points for the ground and powered seemed soldered into the USB port correctly.
I do remember reading something concerning the pins for the USB are wired differently (last 2 pins are shorted - on the Universal-wiki I think) for powered USB charge. Maybe that's why the cradle AC charger doesn't work while the USB cable works.
FYI, I've tried putting both the AC and the USB and you'll find that having the AC in is useless....you're just wasting electricity cos the PDA is still being charged by the cable (just turn off you PC and you'll find that the PDA is not charging).
Does your cradle have the annoying blue LED?
I think all aftermarket cradles are created equal = "CRAP"
If somebody out there have a cradle that have AC that works, please post where you bought it so that others will know which one to get.

Sounds like I have the same cradle as you fella , I've tried the usb on its own and it seems to charge ok .. I tested it by putting a movie on and leaving it plugged in, started at 67% its now 77% so its charging through the usb.. dam it .. I could probably send the cradle back since I wanted it mainly for AC charging. Wish there was another one I could get that worked!
Thinking of getting this one instead:

What dya think?
joe....
According to this guy on this thread:
http://forum.xda-developers.com/showthread.php?p=1097137&posted=1#post1097137
his is working just fine.
If you can return it for another one, maybe you'll get one that's working properly.
i'm thinking maybe we have pda's from the same manufacture date.. and the hardware revisions are different and thats why our desktop chargers dont work, surely its not coincidence that both of ours dont work?
And if thats the case getting another of the same won't do much good.. theres just no way to be sure about any of this, think I may just send it back and try a different one entirely
Joe,
Good luck!
My himalaya has stopped charging through the cradle or car charger. It syncs and charges through the usb and my wired sat nav connects up but neither method charges my phone anymore. Obviously the battery will die down quick when I use my tom tom so I need that to work and only being able to charge via usb is a pain and inconvienient.
What can I do to fix it??
What kind of charging connector your PDA has? ie. my universal has a mini usb, it is used to charge/sync, it can be done at the same time, on the contrary an old Ipaq (series H38XX & H39XX) had two different ways for power to arrive to the PDA, this means that you could charge it with its charger or via usb while syncing or just charge via usb.
Why am I asking this?
In this way I'm trying to understand if you could have a problem with a connector/cable (different connector for charging with the craddle/car charger and usb charging) or you could have other problems.
If it's possible for you, take some pictures of your pda's syncing and/or charging connector, to your craddle, car charger and usb syncing/charging cable.
Possible causes for your problem are:
Defective craddle/car chargers, defects can be not the chargers themselves, but the cables that go from the chargers to the PDA.
Defective/unsoldered PDA power/charging connector, it is not so unusual that after you pull the cable too hard, without pressing the unlocking secures (in case your cables have them), accidentally hit your charging cable/craddle or the PDA itself while they are tied togheter you cause a malfunction due to a false contact or a broken cable.
See if one of this might be the cause in your case, how? Can you have a borrowed craddle/car charger to verify if yours are ok?
Try to move the charging cable/craddle or the PDA (easy and carefully) to see if the PDA begins to charge.
Let me know how it goes.
unfortunately I don't know anyone that has an XDA - so no other chargers unless I try the o2 shop.
THe XDA has a cradle with a usb connector that can charge and sync and also a mains lead which plugs into the cradle or there is a little adaptor piece(which I've lost) which plugs straight into the xda to charge. I stiooed using that because it would push in properly.
My thoughts are that its the PDA itself as the car charger was only bought december whilst I have had the PDA and cradle since 2004 and they both stopped charging at the same time. The adaptor stopped chargin in the summer.
Ok, as title suggest, I think my charging port may be faulty - Uding Ampere it says I'm recieving, on average, about 700mA's, and it's not consistant, mAs are going up and down constantly between 1000 and as low as 10 - Also says, 3.86volts.
The same cable will deliver a constantly stream of 1200mA's to my Galaxy S5 with a voltage of around 4.021v
So, my question is, is The Tab S charging port faulty? Could someone do me a solid and check their stats with Ampere? Would appreciate it alot. Noticed slow charging after I had plugged in a micro usb to usb port adapter that was a tight fit in The Tab S, So think it may have borked the chergaing port. :crying:
Thanks guys.
You need this one to check which one is bad
http://www.ebay.com/itm/LED-LCD-Dig...370707?hash=item2ee3bded53:g:ypwAAOSwQItT4JcK
You should use the correct charger 5Volts, 2 Amps output ( it's on the side of your charger ) and correct USB cable ( 2 Amps ).
Use the cable which is rated for 1 amp also gives you the low reading.
The reading for correct charger and cable should be 5 Volts and 1.7 Amps. Test with known good working charger and cable first. If everything is the same, you should test with a new USB flex cable, which is under $10. Go further, it may require advanced knowledge to check battery connectors : on board and the battery cables.
With many variables, nobody can give you the correct answers except yourself by checking one by one : charger, cable, USB port, battery connectors. The last resort is bad mainboard if everything else is checked.

Phone shows charging over USB instead of AC charger....
It will work fine for a few days...then revert to this...before charging normally
I'm losing battery power while it is charging take forever to charge.. When it is working fine I'll charge in about 2 hours. Strange part is it goes back and forth
Shows low amps using ampere app when problem persists. With phone off charges like it normally would
It is not the cable or charger. I have tried a few
Is this a faulty charging port or battery issue? Confused at this point
It should display AC charger not USB charging with a AC charger
BTW I'm not holding USB cable on weird angles trying to charge it
USB port issue.
Try different usb cable

If anyone has had similar problem or has knowledge please share
Do not want to solder a new charging port for no reason
Thanks for the help *sarcasm*
Fixed it myself
I have gs9, original usb type-c cable and charger. I found that cable can charge my phone just from one side not both sides despite it is type-c . How can find what the issue is? How can i fix it?
I checked another original cable+ charger, the problem is same as mentioned above. Just one side which is the same in two cables can charge my phone.

I had the same problem with my headphones once...turned out to be bad soldering on the usb type c port of my headphone (it was a charging and data port for new firmware) and had them replaced so maybe you can get your phone replaced too
If you have had your device for less than 14 days then I would recommend that you take it back to the retailer for a replacement. Otherwise take it to a Samsung Service Center for repairs.
