How much moisture do you think it takes to short out an electrical circuit?
For water to have gotten in the case far enough to damage the battery, it would have ruined more than that.
Did the phone stay on after you dropped it? Then no, it's not your battery.
Have you tried just letting the phone sit, off, and dry out, before trying it again?

Hi thanks 4 ur reply yes the phone stayed on after it was working fine till I put the charging in it. It would not charge the battery.

Just let it sit out over night...take the back cover off and battery out and just let it sit around...or if you have a blow dryer you can try that but dont put it to close

Good advice, but I'll just amend it to say ... ONLY when the battery is OUT. In fact, be sure to give it a few minutes after trying that before booting it back up. And, only point it at the back cover, it could easily have negative effects on the screen.

Hi appreciate the help everyone yeah I left battery out last night it still won't charge this morning, I am using the usb to adapter that came with the phone 2 charge it. This happen once with my HTC 8125 & I had to get a original charger to bring the phone back to life no charger will charge it but the original after u can use anyone, I will update u later and c how that worked out.

Hi guys on found this online on ppctechs.com it says "In some cases, your HTC Touch Pro 2 will not charge from an AC/DC adapter or other charging accessory when the battery life is below 30 percent."

Are you trying to charge from a USB port or an AC adapter?
Maybe the USB port is bad.
Do you have another charger to try?

Hi I try usb to adapter that came with the phone 3 different wall chargers and still not charging, last 2 try is a car charger don't have one and there is 1 ft of snow outside

Hi I ordered a new battery & a battery wall charger off ebay when I get it I will update u on how things when.

Hi I got the wall charger battery is fine I think I have a faulty usb port cuz the phone still won't charge or connect via usb can it be u need software to charge

have the same issue (didnt drop it in snow though) it won't charge via usb or car charger.
So you got a new battery and still won't charge via USB?
Mine connects to my pc fine, just doesn't charge. Ordered a new mugen power 1800mah battery, waiting for it to get here to see if its a battery problem.

yeah still don't charge plus it is in a bootloader loop think it is a hardware problem with the usb port

I know that, for example, the iPhone has about 4 moisture sensors, one inside the USB connector port, one in the headphone jack, and 2 inside the phone, the last 2 will trigger things like reboots or even blocking the charge. Put the phone in silica gel or, more convenient, a bag with dry rice (that's how I've saved my old lg vu) for couple of days...

Have you tried plugging it into the mains (wall) charger and let it sit for a while?
That fixed my bootloader loop, turns out the battery was too weak to power the device on that it went to bootloader. I Just plugged it into the wall charger and ignored it, came back and it was working fine and charging.
But it won't charge via usb or car charger

I had the same loop problem but mine never recovered. Never dropped it in anything wet either. I let it die once and could never get it to turn all the way back on because it would just try to boot and then shut off again over and over. Had to send it back for a new phone. If its new enough and there is no water damage marks then I would send it back for a new one.

Hi everyone phone is fix now it was a bad usb port that was causing the bootloader loop so protected your usb port.

I have a problem with my USB port too. Nope, no snow. Just realized one day why my internet kept getting disconnected. It's because the USB connection was the problem. Jiggling it around gets the orange (or green when battery is full) light to come on and computer will recognize it... or it starts charging from wall charger. I think the phone's USB connection is bad. Is this a common problem with this phone?

It seems to be yes, I've seen quite a number of people who've had this type of problem on the Rhodium end up finding out it was a bad USB port on the phone...I think HTC just might have used ones that weren't nearly sturdy enough.

USB Port of Kaiser TYTN II very sensitive to moisture

[Q] Phone not charging (not charger, battery, or cable)

Hello,
Recently the charge light on my phone started flashing when I plug it in to charge. While plugged in the phone switches to charging and not charging with the flashing light, as if I was plugging in the phone and unplugging it. Fortunately I have an external charger I can charge my batteries because it never charges while in the phone.
Reading other posts I've read that this could be due to an overheating battery, bad charger, bad cable or a bad battery. I have different batteries, chargers and cables and all have yielded the same result.
I'm Running CM on my Dinc . Possibly coincidentally this problem started when I installed adfree. However I have removed adfree and even flashed my phone with the newest stable CM.
Any ideas? Perhaps something fried in my phone.
Thanks in advance!

the port might be dead. will it still transfer over usb to a pc?

Thanks for the reply!
Nope, not recognized at all. Not even with USB debugging on.
That is what I was thinking to, but always optimistic of what people have done here. Kinda surprised that I haven't been able to find anyone with the same issue. Just lucky to have a unique problem!
Guess I have a hard decision ahead.... Rezound or Nexus

yeah no USB response is never a good thing.
How long have you had the phone? do you have the insurance?

Had this happened to me once due to the charging port being dirty. I just took an old toothbrush and some alcohol and brushed the dirt out. Has worked fine ever since.

Can anyone help me out with Tab Pro 8.4 Battery problem?

Ok, well...
I'm Korean, and I've searched almost every Korean tablet forums, yet can't find the reason :crying:
So I came to here, XDA.
The problem is, my Tab Pro 8.4 won't charge at all.
It's looks like an usual charging problem of Tab Pro 8.4, however, mine's little bit different.
With the charger plugged in and tablet is on, I can see the lighting shape on the battery icon at the status bar (which appears the charger is plugged in) ,
but no matter how long I charge the tablet, it's 0% and turn off after like...10 secs.
With the charger plugged in and tablet is off, I can see the battery pic appears on the middle of the black screen.
BUT, like the former situation, no matter how long I charge the tablet, I turn it on and it dies quickly.
SO, my problem is this, and i can't find a tiny reason why my tablet got (or how to fix) this battery problem.
Never seen a battery problem like I have right now.
I got several ideas about this. (Hope this will help you to fix my situation )
1. My tablet's rom is not pure. (But not rooted.)
As far as I remember, I applied the Ukrainian version about 3 weeks before.
Is it possible the this is the reason?
If so, wiping the original rom and applying the new one would help me?
2. Is it possible that the battery and the tablet connection got a problem?
If so, open it by myself and re-positioning the battery would help me?
3. The battery charger part might be damaged.
Then it leaves me the one option {GO TO THE SERVICE CENTER} ?
4. well...not 4.
have no idea.
Using same charger which is official SAMSUNG's.
I will keep monitoring this thread.
Little help to poor man would be really grateful, THX
PS
I just tested download mod.
With the charger is plugged in, it's working.

to see if the charger is bad, fully shut tablet down and then try to plug the tablet into a USB port on a computer and wait about 8 hours, then unplug it and see if the tablet holds any charge (battery might still be low but it should have enough charge to run awhile), if above works then it means you need another wall charger (5v 2.1A).
if it still just powers off or dies then it means the battery is bad or not connected or something else is wrong with it.
1. Try another USB cable
2. Try another 5v 2.1A wall charger
3. Try charging on a PC
4. replace battery.

To verify your tablet is charging, you need this little tool
http://www.ebay.com/sch/i.html?_fro...usb+power+current+and+voltage+tester&_sacat=0
Current should be 1.5 to 1.7 Amps, voltage should be 5 to 5.2 V
If the charging current is under 1.5 A, you should change different USB cable or adapter
If cable and adapter are fine, the next is charging port, it's easy to replace if your is defective.
Never use usb port on computer to charge, it only supply 0.5 A and your tablet needs at least 2 Amps for charging properly.
These are basic steps you need to do, without basic information I cannot tell what is wrong with your tablet: not charging or bad battery, or the worst: bad main board.
The one you have to verify: your tablet is drawing normal charging current around 1.5 to 1.7 Amps when plugged in. You can not troubleshoot problem just by guessing.
The most common problem of Samsung tablets are cracked Battery connector, a simple re-solder will fix the charging problem.
There are many unknowns, you have to eliminate charger, usb cable, usb charging port as the source of problem first. Then next look for battery or battery connector.
Otherwise, you will confuse yourself and others what causing the problem. Elimination is the key to figure out problem from many unknowns, one by one at a time. There's no short cut , otherwise, you can not figure out where the problem comes from.
I see many users send their tablets for service and the problem just comes from a bad cable because they have no idea what's wrong with their tablets.

You can charge from a computer fine just as long as the tablet is fully shutdown first (so you see the battery icon scrolling), this will ensure the 500ma will go directly to the battery and not running the tablet and os, it will charge very slowly but it will eventually reach 100% as nothing is drawing power from the battery to drain it (though I would only charge to 20%, to see if it holds a charge), however this method is just for diagnosing if the charger is bad and have no current alternatives, obviously this should not be a long term solution and never used when the tablet is running, but rather to see if the battery can hold any charge at all.
if you have another 5v 1+A charger laying around then use that instead., if the charger is the problem you can pick them up pretty cheap off ebay (make sure the hallmark icons and model number match to avoid knockoffs)

To see what is wrong with charging problem, you should never use wrong charger like 5V, 1 A or a USB port on computer. If using a 5V, 2A charger and a correct USB , any reading is under 1.5 A, there is something wrong with charger, or USB cable, or USB charging port, or battery connector. Even wrong USB cable, the one has only max of 1A, also is the source of slow charging.

His issue is not with slow charging, it was as soon as he unplugged it the tablet instantly powered off, in this case if the battery is 100% dead then damage is already done and once a lithium battery is completely discharged then most likely no charger whatever the mA is will bring it back...this is why I was saying to charge it from whatever source since you need to get a charge into the battery before it's irreversible damage.
However after re-reading ops post I think it's safe to rule out the charger as the problem because he said he could run the tablet with it plugged in (so that means the Charger is providing enough power to run the tablet) according to my mA reader this alone is around 500-700mA in standard use / full brightness
This also mean we can rule out a bad Micro USB port on the tablet since a broken one wouldn't allow power to the tablet.
the problem likely lies with a bad battery or a bad battery connection, the probably only option at this point would be for him to have samsung service it or take the chance to replace the battery.
(BTW I have all the tools nessasary and I know what can and can't charge this tablet)
Yes I know it needs a 2.1a charger to charge it while it's actively running since a good portion of that power will go into running the tablet and LCD if needed, it does not need a 2.1A charger when it is powered off and 500mA to 2.1mA will still charge it.

Three is a thread here talking about reseating the battery. Look it up. That may help.

Agree with otyg. I recently had a similar problem. My galaxy tab s 8.4 would power off immediately after being removed from power. It would register as having 100% charge while turned off, but once powered on, the tablet would show 4% charged or lower. Another thread on this site mentioned that the battery contacts on the motherboard have cracked for some owners creating symptoms like ours. I resolved the issue by applying a low resistance conductive adhesive to the cracked pins linking the battery to the motherboard. If this happens to be your problem be very careful because there are other contacts next to the battery pins. Good luck!

G4 Charge/USB port issues

I've had my G4 since almost launch day and within weeks the supplied USB cable stopped charging the phone. I thought it was a cable problem, but it worked fine with other devices.
I tried other cables with the G4 and these still charged it so I thought nothing more of it until charging degraded with every USB cable I own to where the phone would only charge 20-30% during an overnight charge and the phone would frequently not recognise it was plugged in at all. I contacted LG who did a repair under warranty and all was fine.
I've now had the repaired phone back for about 3 weeks and the same problems are starting up again and it's only a matter of time until I am forced to return again for a repair.
Is anyone else having similar problems? I thought I may have just had an unlucky manufacturing problem, and the LG reps confirmed that to repair my phone they basically replace all the internal circuit boards and components rather than just replacing the individual component that is faulty (in this case the USB/charging port)

Basic debugging includes asking stupid questions, so please forgive but still answer any of those
Are you using a different charger? If so, check if that one is within specifications and if you do send in for repair again, use a different charger.
Are you propping up the device at an odd/weird angle or in a dock of some sort with the cable attached?
(As they replaced the entire print, it's probably not this, just the USB-micro port bent or broken.)
You could double check the wall outlets being used, there might be some kind of electrical problem there.
Either using all kinds of fancy electical testing gadgets, or stick a USB light into the hub or charger, does it flicker?
When sending it back for repairs, did they check the stock charger as well?
Hopefully these questions help you find any logical or plausible cause.

Hi FreezyExp,
1. I am using the standard charger that came with the phone, but this has not been repaired/replaced. I have tried other chargers too, but all the same issue.
2. No weird propping up or anything like that. If I hold my phone while it is plugged in it is constantly vibrating as the charger connects and disconnects, and if I place it on the desk to charge I have to ensure that I have at least 3-4" of cabe "on the desk" to give it enough support to make the connection.
3. Wall connection is fine and I have tried it with a range of outlets around the home, both with extension sockets used and plugged directly into the wall and there is no different. No flickering light when using a USB light either.
4. When I sent it back all they asked me to return was the main section of the handset - so no battery or rear cover, no cables or chargers etc
It does seem to be the same issue as last time, a USB connection becoming loose from the main motherboard, but it seems weird that I have had the same issue twice in the space of 4-5 months.

I've been having some sort of problem with my G4 usb port. If I plug it in to a computer, it will lose connection and get a connection again if I barely touch the end of the cord at the phone end. I've tried many different cords and different usb ports on my computer, but it still has problems.
I can't fast charge, either. When I plug it in to fast charge, it actually starts discharging even faster. I've had some extreme battery life problems, too. It drained from 100-36 the other night with everything disabled, and it's been doing that kind of thing a lot lately. I'm guessing that the charging port is what's messing up my battery life because it won't charge correctly.
Never dropped it or anything.

I got my G4 on January 24 and my USB port has also failed. I am getting a replacement from Verizon, but am concerned that a six month old phone has this issue.

I also own a G4 H815. A while ago the phone started not receiving any charge from the cable and I would have to prop it up from right under the cable's micro usb end. Thought it was because it was bent inside the port and not making connection with the cable so I had the port replaced. Now I'm experiencing the same problem and I think it might be the cable that's already gone kaput and is effing up the port itself. I took the phone to the same place to get the port replaced again and bought new cables (I lost both the original adapter and the cable, which were charging slow anyway. Now using a 2A Asus adapter which works great) and when I asked the guy at the repair shop, he says it's a chronic issue with G4 devices. I don't really understand how it would happen twice in just a few months even with a new charger port. What should I make of this? Did they replace my port with an already faulty one, cahrged me full price and now trying to sell this bogus or am I really doomed with this phone?

Quick Charge 3.0 and USB C not working

So charging is extremely slow now: max 280mA showing in Ampere app. Tried different cables and chargers(QC3.0 certified), charging speed remains the same.
I can't connect to PC anymore. Windows doesn't even make a sound when I connect the phone to PC. Showing no device.
Headphones connected to USB port are playing only one audio channel.
I've been using LOS 15.1 since last summer without problems, haven't done any updates since. The problem with USB port emerged a month ago and I am almost convinced it's a HW issue. AIDA64 indicates no temperatures over 36°C in thermal section so sensors are working fine I guess.
Anyone tried these charging ports from Aliexpress? Comments indicate that they are not the same as the original.

It really sounds as hardware problem. I asume you already tried with the phone off, and after factory reset and the problem persists.
In my experience, the original lower board have fuses which are expensive and are replaced by resistors on chinese replacements. If you dont want to lose this, try going into a repair shop and have the USB-C port replaced or desoldered/resoldered from the board. Must be done by experienced guy or it will be melted.
I'd buy the replacement board anyway. As long as you don't use crappy chargers, you shouldnt need the fuse too much, and also, the phone have another fuse in the motherboard.
If you have not tried with the phone off, try it. I got the xiaomi wireless charger and it works like crap with the phone on. it disconnects/maintains chage/stops charging A LOT, but if I charge the phone turned off it charges without issues at full power (8-10W according to my USB meter). Maybe is just the firmware being an ass

Thank you for insights. I confirm that hard reset nor charging solved the missing QC3.0 functionality. It's clearly a HW issue.
The whole situation was caused by losing my original charger on a trip and then using certified QC3.0 charger (not from Xiaomi) and unfortunately - cheap Chinese micro USB C cable. I can't stress this more... Never use cheap cables (or chargers) they can literally fry up your port. In this case it was definitely the cable eventhough it worked fine for 5 months.
It seems (from comments) that beside fuses the charging ports from Aliexpress are missing the possibility to transfer data over USB as well. Which is not that crucial because FTP over WiFi is bearable. The real problem that I need to fix is quick charging because with 280mA on Ampere app it takes 5 hours to charge this phone.
The charging port I've bought on Ali is on its way so I will update this thread in a few weeks after inserting it into the phone.

Losing data over usb is quite a problem if you are into custom roms/mods on native miui (which resets the recovery on each update).
Hope that ali's board does have this funcionality. About charging, you can get locally a wireless charger for now, though for me it only charges fast when the phone is idle, using it always just keeps the charge (probably to avoid overheating).

So how the story ends? We're you able to solve the problem?

I had the same issue with my Mix 2. bought a replacement port from Aliexpress and Witrigs.com. As posted on most forums these replacement ports don't support fast charging (in most cases) and no USB data transfer (this is the case with mine).
I had dropped a message on the witrigs.com website to confirm if their supposedly 'OEM' replacement supports data over USB (it looks much more like the original board in the phone that the 'custom' replica one that is half the price).
but I'm not very hopeful of that being the case, given someone has already left a comment on the product page indicating they bought the OEM version and faced the same issue with no quick charging or USB data transfer

Got some problem when i lost my usb travel charger on a trip.
and now my phone was too slow and cant transfer data even if i buy the new authentic from xiaomi store.
i hard reset for 3 times and but no luck.
omg -___-

I know it's old, but I'll let you in on my problem.
I have the Mi Mix 2 and it was happily fast charging until recently. Still the original plug and cable
I have tried all sorts of theories to get it fixed and one person said to charge it while turned off
So I plugged in my usb cable and turned off my phone. Only for it to automatically fire up and go into fastboot. No charging. Just fastboot on the screen
Obviously I can get out of fastboot mode again, but is mine an option change in the settings that needs addressing?
Thanks
