Broken USB/charging port?

I'm not sure if this is the right place to ask this, please excuse my ignorant.
I have an EVO that won't charge. I've read a lot from Google search results that this is a common problem among many users. However, the port seems to be working, because my computer will recognize the phone and storage when I plug it in. The charge led will come on, and the indicator on the phone will say that it's charging, but the phone is actually only discharging while plugged in. Eventually the led will turn itself off, and the phone stops telling me that it's charging when the battery is down to its last drop.
I hope that someone with similar problem can help me with fixing this, or if anyone cause tell me if it's possible to fix? I want to send it in to HTC since I think the phone is under warranty, even if I don't have the protection plan from Sprint? The problem is the touch glass is cracks, and I don't know if they'll fix the USB port without saying that I broke it and won't cover that under the warranty. I want to buy a new screen and replace the broken one, but if I open up the phone it would void the warranty as well...
So I'm stuck with a discharging phone, cracked screen, and having to carry around 3 separate batteries everyday, and I have no idea what step I need to take.
Please help?

Have you tried plugging it into another charger? It may just be the charger that is screwed up. If this behavior pattern is consistent across multiple chargers then you may want to talk to Sprint to see what options you have.

Doubt it's the charger as it was stated that the computer connection works - should get a bit of a charge from that. I agree that a Sprint visit is due.

Just went through this myself! Would plug my phone in before bed and wake up with the phone at 2% or so. Thought it was the battery- so i took my battery to have the sprint store check it, they did say it was bad. So i bought 2 batteries off ebay.
I got the batteries and still had the issue. So then I took my phone to the sprint store and had them check the micro-usb port. They said it was fine and they cleaned it out cause dirt/dust was in it. Still had the problem..
So I bought a new micro-usb cable of monoprice (still using the same wall charger) , and that solved the issue! Had a bad cable. Now my phone charges super quickly in matter of 4hrs.

It could still be the charger. The USB cable sends data and power through different pins. So a bad cable could still transfer data while not pushing a charge.

It's gotta be the port happen to mine and I was able to get it fix as long as the port was still attached to the motherboard, if its not attached then have to go thru the insurance.
EVO with Identity Crisis

I was able to connect to my computer and send data just fine with the old (broken) usb cable.

I've tried three different cable and a car charger, same result; they all say the phone is charging but it only gets discharged. USB/storage connection works. Last time the Sprint store said the battery is faulty, but I have 3 different ones and neither will get charged with the phone plugged in, an external charger will work.

Definitely sounds like a port issue then. If you return to Sprint and review what you've done, as well as the result of your previous trip, then they should be able to take care of you. If they try to tell you it's the battery again just stand your ground. Good luck.

I had a similar issue. I tried everything. It wasn't until I found my HTC cable that it started charging again. I work in IT and tried cables from everything I could get my hands on (blackberries, external drives etc. ) The cable that came with my phone was the only thing that worked.

If you replaced the port yourself, I would love to know how to do it!
Took the phone back to Sprint and they said there's nothing they can do. I don't have the protection plan so I couldn't even pay the $100 to get it replaced (although I probably wouldn't as I can upgrade my contract and get a new phone soon). They also told me that HTC wouldn't cover it under their warranty because the screen is cracked and they will blame that on me for misused. I tried to check the warranty policy on HTC, but the page is not even available. Does anyone have experience dealing with HTC? I bought a replacement screen, I'd like to replace the screen but don't want to open up the phone if there's a chance HTC will fix the USB port...

HTC EVO 4G Won't - Stopped Charging Battery Issue
Hey Guys,
Two nights ago I woke up to an EVO that was plugged in with a Cellet
extractable charging cord, as it is just about every night. But, the phone was
still showing that it was charging the battery, animation with lighting bolt,
at only 50% charged after about 6.5 hours of charging. Hmmm....
The latter after trying to charge in the coffee shop first with Cellet chord in the
wall then a portable 3500mah solar portable charger; the phone not seeming to
charge at or past 50% charged.
My EVO is rooted but still with the stock ROM and the gingerbread 2.3.3 OTA
update. The battery is a Seido 1750mah and SetCPU is at 245 - 998mhz. The
phone has only been rooted for a few weeks, but I don't see where rooting
would interfere with battery charging.
I've pulled the battery out, several times to no avail. Switched back to the
stock battery, same results. However, if the battery is less than 50% full
the phone will charge the battery to 25% or 50%, weird. If the battery is
at 75% or more full, the phone will top off the charge to a green LED at 100%,
sometimes. Sometimes it won't fully charge the battery. Weird.
I read different posts regarding poor USB chords so I pulled out the stock
micro USB to USB, a charge only chord I figured, and am trying to top
off the Seido battery, which it seems to be doing as it's now full green but
still charging as the animation shows the bolt in the battery and the LED
is still orange.
If put the batteries in the Seido wall charger, the thing the size of a deck
of cards, both batteries fully charge.
I also use Screen Off by Iwashi Soft. That app has worked pretty well with just
a little funkiness now and then. However, while plugged in, I hit the power
button, instead of the home button to turn on the home screen. The phone
wouldn't open to any screen nor would turn on or off. So I ended up
yanking the battery to turn it off then reinstalled battery and turned phone back
on. I don't know if that had any effect on the charging issue, but I took
the icon off the homescreen and am using the power button only, for now.
I don't think both batteries are faulty at the same time at this point. I
don't know if the screen off app caused some wake issue that interferes with
charging the battery.
I do know that when plugging in the phone to charge there's a bit of clunkiness
initially as the phone locks for a second before allowing use for screen or app
and that's always been the case since the gb update. Also, the LED doesn't
always turn green from amber when fully charged with the screen off until
you reboot or use the phone in some way while still plugged in. So there is
some kind of wake issue in the stock ROM. But the latter has never stopped
the battery from charging.
I do know that Plume, the twitter app, started acting clunky with not updating
in the background unless I opened the app at least once after a reboot. But
I don't know if the latter is a wake issue.
Battery still seems normal. Heavy normal use, lots of SMS, tweets, Pulse reading,
Dolphin browsing, I'll kill 50% or more of the battery in 4+ hours. Otherwise, the
phone mostly in standby with periodic email and twitter reads, the battery lasts
all day or more than 24 hours. But the latter rarely happens anymore because I'm
a user.
The battery just went full charge with the stock charging cable just now.
This morning, I woke up with a dead phone, auto shutoff even though it was
plugged in which I did after solitaire and before going to sleep; as a charging
test.
I don't know if it's the phone or the Cellet retractable cord or both that's
stopping the battery from fully charging normally and consistently. I'll need
to get another data-charge combo chord and do more testing; and a new ROM.
Any ideas anybody?

try a new rom and also try using the stock charger and usb cable. Check inside your usb port on your phone for dust as well. Also go into recovery and wipe your battery stats. In the wipe menu for amonRa and under advanced (maybe here, i dont use cwm on my phone) in clockworkmod. also wipe your dalvik-cache just to clear any issues you may have, restart and give it a test. good luck

I just bought a phone with a broken charger port. Broke clean off the board, so my next step is to try to get liquid solder and stick it to the board. Did you take ur phone apart to see if the port is lose?

So I used the stock USB charging chord. Sure enough, it charged the phone.
Then I tried the portable charger at the coffee shop, worked. So the Cellet retractable
chord obviously had a short or something damaged/shorted for the charging part of
the cable after a year + of use and abuse.
What I don't understand, and haven't researched, is why there are charge only
chords; the stock USB HTC chord charges the phone, but the PC won't recognize
the phone's Micro SD card or the phone as an external drive. I presume the duo use
chords have a data path as well as a charging path. And yes, I know to switch the
phone from charge only to disk drive. The Cellet chord would provide the PC with
recognition for the phone's drive.
Considering the latter, what I'm not sure of, and haven't researched, is why when
the phone stopped charging, the chord eventually stopped charging, the phone
status still showed it as charging; the amber LED light on and the battery icon
in charging animation with white bolt showing? I presume that the charging path
still triggered the charging status, except once when I turned the screen back
on the battery icon was not animated and the white bolt not showing so I unplugged
the chord then plugged it back in where the battery icon animation continued.
Fortunately, or not, this forum returned 600+ results for 'battery not charging' and after
sifting through a few, the charging chord was mentioned which prevented a Sprint trip
and me contacting Seido; thankfully.
So I think manufacturers and ROM/kernel developers should visit this issue as a chord
that actually is not charging, or charging at an absurdly low rate, should trigger some alert
and not show a battery icon animation that appears to be charging normally.

[POSSIBLE FIX] Flashing red light - dead phone/inferior USB cables

Today I had my One X happily connected to my pc, just transferring some files over by USB. Then when I wanted to disconnect it, it showed a lot of 'not getting enough current to charge and operate at the same time' messages. Dismissed them all, though it was time to put it on the wall charger, seen it's critical battery status.
Once I disconnected the phone, it immediately powered off and would not come back to life again. It was, however, greeting me with a flashing red light while on the wall charger. No matter what I tried (bootloader, long hold power button, charge it for some time), it remained completely dead.
Now I did get some new micro usb cables from eBay. Very cheap ones. Now I think these are the culprit. Apparently, while in file transfer mode, these cables were unable to provide sufficient current, causing the phone to drain the battery completely. Once I wanted to charge it, it couldn't boot to charger mode due to the battery being completely empty.
Hooking up with the original HTC cable again, it still showed the red flashing light. Exact same behavior. Until I (for the heck of it) tried to bash the power button quickly. It suddenly came back to life again and started charging again through PC.
If you find yourself in the same situation with bad USB leads (something to do with resistance of the cable?) or a red blinking light, try tapping the power button quickly instead of trying to boot into recovery mode. It might save you a postal return and a week or 3. Or your ass, if you rooted it before it stopped charging.

When I had my sensation I had this every now and then. I had to remove the battery to get it to work.. Nice to know that there appears to be something I can do to sort this out if I get this now

It was mentioned that the flashing red (or orange?) meant that the temp was too high.
Just let it cool down, and it will come back.

It definitely wasn't hot. Also, it wasn't flashing orange. Just slowly red.

flashing orange - low battery
flashing red - very low battery
It could well be the battery level is considered too low to operate. So to protect the circuit and the battery, the device is not allowed to turn on until it is sufficiently charged.

This is currently (no pun intended) happening to my one x, left it plugged into my pc via the htc usb and got flashing red light after a couple of minutes, after a couple of minutes more it stopped flashing and became a solid red light (a sign it is charging from v low battery from m experience) pressed the power button and voilà its come back on. I can't believe htc would let the device get to such a critical state of battery before powering down, can anyone enlighten me as to why it would do this?
(thinking about it i was showcasing the handset to my apple touting buddy and had 3 pretty heavy apps running, it was a couple of hours after i noticed it had killed itself so i'm guessing they were still draining away the power from the background??)

I'm having the same problem. My phone was off when i got home and it wouldn't turn on (I assume the battery was dead). When I put it on the wall charger the red the red light didn't turn on and my phone wouldn't boot. I tried several chargers and cables and also tried to connect it to my pc. After leaving the phone for a few hours (unplugged) i tried to connect it to my pc again and i got the blinking red light. A few minutes later I decided to plug it into the wall and the red light turned on and now it is working normally.
anyone got an idea why it didn't charge at first?

agree chaging cable fixed my flashing red light problem

Poor quality charging/data cable
A poor quality charging/data cable will also impact the ability to charge the HOX in your car. I have two cars, in one I was using an old Blackberry cable and Griffin charge adapter (1amp output) to charge the phone whilst using Car Dock and navigation software. After trial and error I got the screen brightness correct and the phone charged satisfactorily. I say satisfactorily because I still think any electronic device which is connected to an external power supply of sufficient electrical current should operate and charge at full spec. In my other car (1996 Land Rover Discovery) I was using a cheap ebay charging/data cable. Using the same apps and screen brightness the HOX would lose all charge over about a two hour period. With the same Blackberry cable used in my other car, no problem. Hence the cheap ebay cables are now in the bin.

The HTC-cable isn't that good too. I use a Nokia-charger to charge my HOX. Charging is much quicker. Maybe the HTC--charger (and cable) was crappy but i never touch them, i use the Nokia charger and dito USB cable.

Thank you!

thank you! Thank you! That cheap usb was totally the problem!

Small update.
This problem just happened to me. 1 cord gave me flashing red while plugged into the wall and pc. I switched to my other cable and its charging and functioning normally. Cord was the problem.

I had a similar issue with my one x.
It discharged completely, then when I went to charge it I just got the red blinking light for ages. I left it charging overnight thinking the battery was so low it needed a while to charge enough to be able to switch on.
But in the morning it was still flashing and the phone was very hot, so I thought the battery was blown.
So I came on here and saw a suggestion about holding the power button and the volume down button. It went to the boot menu and said there was not enough power for a factory reset or something, so I selected recovery. I then got a warning icon and the phone switched off again, but this time with a solid red light. A
After a while I was able to turn it back on again.
Hope this helps.

Wellllll
I have the HTC One VX. I know this isn't in the same topic, but since I found the thing that helped/worked here, I thought I should share my experience. So I bought my new phone on Sunday, so it is roughly 5 days old...not even a full week. I charged the phone before I went to bed to roughly 80%. I made sure all apps and what not were turned off and pressed the lock button. I woke up in the morning and checked my phone to see what time it was. Had 78% battery left. I left it on my dresser for roughly 2 hours and when I got back from class, I grabbed my phone to check if I had any messages.
The phone didn't turn on and I didn't even get the flashing orange/red light. So I tried charging it and nothing. I changed wires and nothing. I frantically searched the internet and stumbled upon this forum/thread. I tapped the power button at least 15 times consecutively and the phone barely flashed orange. I tried to plug it in again and rapidly pressed the power button 10 more times and the screen finally turned on. It started charging and I checked the battery life. Somehow, in 2 hours my phone drained itself of 78% battery life when it was on the lock screen (its also set to lock after 15 seconds of inactivity) to the point where it couldn't even turn on.
The phone/battery was not even warm/hot or w/e. It had not touched any water. No idea what caused the immense power drain, but glad it is working. Thank you so much for this help

woops, wrong thread

It happens to me allso in this morning, in my opinion is like this: The phone is turning off when basicly you have a little bit batt (lets say something around 5% max) and its turning off to protect data and is showing to you batt empty. Then it cames a user with a charger connected to a power supply (house charger,car charger or directly to pc's usb). You must use a good usb to micro-usb charger (the original ones are't good usb cables) try to use a Nokia usb to micro-usb cable, This was the first problem most usualy. The second one is to pay a HUGE attention to UC, don't uc'it so much because then the charger board will not charge your batt so well. Keep yours HOX safe and anjoy it. Have a nice day boys and girls.

N750 refuse to charge.

My N750 with stock ROM 4.4.2 refuses to charge normally. The led was off which being connected to USB wall charger. However it showed a grey icon battery for two seconds before the screen was completely off. I noticed the error message popped before this happened (quoted below). It said something related to Samsung power sharing software. Later on I found out the charging problem.
Power Sharing, You must download the app in order to control the amount of power shared. If you connect your device to another device with the Samsung Power Sharing Cable EP-SG900 without the app, the entire battery amount will be tranferred to the other deivice. Connect to Samsung Apps and download the application.

Strangely I did not use power sharing and honestly I don't know what it means and I wasn't doing anything or plan to do things with power sharing. The screen was a little shaky when the error appeared although seconds after that the phones worked normally except I cannot charge my phone. I understand that the phone might still have received current from the charger however small, especially when I charge it under recovery environment which is inconvenient to do. It took 4 hours to reach less than 30 percent under Phil'z Recovery method.
I tried to clean the micro-USB port with a small sharp needle but have no luck. It looked clean to me. I also wiped the data and did factory reset and tried to use different ROM. But still it won't charge. I also tried to use different cable and different AC Adaptor (Sony original charge 2.5 volt) which was working under normal condition but not anymore. I never drop my battery and always recharge before reaching 30 percent. That's my ritual as I read from battery University that frequent charging is much better than letting the Lithium battery goes down to near zero.
Any ideas?
I tried different ROMs to find the best. Is it possible that Samsung crippled the phone after so many reflashes? This is scary.
(UPDATE) The phone is NOT detected by Odin and flashing is not possible.

Tab Pro 8.4 stuck in logo screen/battery loading screen

Hey folks,
I did not use my tab for several months (it was working before), now when I plug it into the charger (either usb or wall socket) it either hangs in a flashing screen sensation of the Samsung galaxy tab pro screen or at the battery screen while this one is just with a loading icon, it does not really charge.
As soon as I unplug the cable it shuts off. I cannot boot into recovery mode, it just hangs there. I can boot into download mode however and I re-installed root and twrp recovery via Odin, however this did not help.
Any other suggestions please?
Appreciate the help.

Plug it into the wall. Leave it plugged into the charger. Hold the power button down for up to 2 minutes. See how it goes!

No change, just keeps rebooting.

When you didn't use the tablet for those several months did you keep it running or did you use the power off option, if you left it running then it probably shut it-self down when battery got low, then the extra time left probably completely depleted the battery causing irreversible damage to the battery (lithium-ion batterys aren't made to deplete to 0 volts it will ruin them), the proper way to store a battery device is to fully charge it then power off the device and it should store for up to a year fine.
sometimes you can give the battery a boost, or maybe the samsung charger blew out, first try another 2+ amp charger and a new cable.
or you can even try your pc usb port connect it for about 10-15 minutes (sometimes the low 500mA current is good to revive completely dead batteries though keep the screen off), see if you can get any voltage back into the battery and if it starts holding a charge, then switch to a proper charger.
if the battery is under 3v the tablet is designed to shut off to protect the battery so if the voltage is less then that it might take some tinkering to get the voltage above that threshold to keep the tablet running.

When you didn't use the tablet for those several months did you keep it running or did you use the power off option, if you left it running then it probably shut it-self down when battery got low, then the extra time left probably completely depleted the battery causing irreversible damage to the battery (lithium-ion batterys aren't made to deplete to 0 volts it will ruin them), the proper way to store a battery device is to fully charge it then power off the device and it should store for up to a year fine.

I'd guess it was left off without powering it down.
When I plug it into the PC via USB or into a power socket I just see the 'Samsung Galaxy Tab Pro SM-T320' log and it is flashing continuously.
RMA? I can get into download mode, but how does that help me? Knox warranty void shows 0x1 - it's voided, correct?

Anyone?

hello
your battery is hs
look here to change it: "https://www.newpower99.com/"
when you leave back your tablet use these: "repair battery life" & "L speed"
regard

thanks
can anyone vouch for this shop? I'll order a battery there and try to repair it myself.

that worked, easy installation and extended battery life

Powering the P600 without the battery?

Hey, I have a messed up P600 tablet here, I messed it up by trying to install a custom ROM but my tablet was very outdated, so now the bootloader will not charge the battery, which is now completely dead. When I took the back off of my tablet, I noticed the battery is connected with 6 small wires (2 red, 2 green and 2 black) and a small white connector. I remember a while ago it was possible to power up an old Android phone by cutting up a USB cable and having the wires touch the pins where the battery connects to, in a certain way to fool the phone it is running off of the battery. Does anybody know if something like this can be pulled off with the P600, possibly a USB to P600 battery's connector exists (although I highly doubt something specific like that would exist lol)? Thanks!

Battery voltage ranges from 3,5 to 4,2 volts while usb is 5 volts. This idea don't sound healthy, but may work or scrap the Note.
If the battery is not completely dead by discharge, the safety circuit/polyfuse will re-arm once connected to the charger and the battery should charge, but the system will notice it's presence only upon unplugging and replugging. I once thought an old mobile of mine was dead, or it's battery, cos the aforementioned trick seeked not to work. Before throwingveverything in the hin, i tried it two or three times more, and it came to life again. But that was deep discharge by a freeze, not by having the device lie around for years w/o charge, then the battery is toast.
