I have tried:
1. different charger/cord
2. hooking up to pc (doesn't recognize anything has been plugged in)
3. cleaning dust out of usb port
4. slightly moving the tab inside the usb port to encourage better connection
Weird things:
When I unplug the usb from the phone, it turns on the screen as if it knows something was unplugged.
When the phone is powered off, it charges very slowly
When I restart the phone, it goes through the app optimization (takes forever) as if I just flashed a new rom

I have a major problem with my Tilt, when it is off and I plug it in, the phone will not charge and instead just boots up into Windows Mobile. While turned on, the phone will not charge; nothing happens when I plug in the USB cable.
The USB connector *looks* OK, no obviously bent pins or damage compared side by side to other HTC phones, but I'm not an expert with a microscope.
Is this a lost cause or are there things I can try to get the device to charge?
i'm not sure my observations will help you but i noticed the following behavior ONCE...i was too lazy to re-test and confirm my theory, but here goes:
1. if the phone was improperly shut down, the phone would turn on and start booting as soon as i would plug in my wall charger (NON HTC, its a generic Motorola charger). in my case, my device charges fine once the boot up has cleared the boot splash screen.
2. using the usb cable plugged into my pc, the phone would NOT turn on when i would plug in the usb cable. i MIGHT have shut down the phone properly prior to trying this but my memory isn't keeping up with me right now
i guess what i'm trying to say is that i THINK the device is built to turn on the moment a charging source is available, that is if it was improperly shut down.
Thanks for that tip...my Tilt is now plugged in via USB and will charge whether or not it is on or off. I still have to try it with the regular AC adapter, but at least it's not dead!
Edit: Everything is good to go Thx for the tip
I appear to be having wired issues related to the USB port as has been previously reported on the Galaxy S2.
When not plugged in to anything, it constantly says it is charging. It will not let me select between USB debugging mode as it says the cable is connected.
Despite it's belief that it is charging, when I actually plug it in to the mains to charge, it doesnt charge!!
If I power off the device, it shuts down correctly, however it will constantly switch between the grey battery icon, then a almost full green one, then off. It then wont allow me to turn on the device. Ive tried plugging it in to the mains (but I guess that as it wont charge this way, this is why it wont let me turn it on this way either) the only way I can boot it up is holding vol up, middle button and power together for 10 seconds or so. It then goes to CWM recover where I can reboot the device
If I plug in a jig, that allows me to connect a USB flash drive, it all seems to work OK. it no longer says it's charging, and i'm able to mount the drive.
The only way I can actually make it charge, is by plugging in to a PC.
Im very careful with my USB connectors, and I can only think that slight dampness may have entered as the phone has been with me in the bathroom during showers.
I dont want to send my phone in for repair, my first plan is to wait it out and hopefully any moisture dries out. Ive tried cleaning the inside of the USB port, but it makes no difference.
If I changed the USB port myself, a) is that a hard task, b) would it solve my issue?
I had a very similar problem with my note.
Solution was to take out the battery and leave the cover off, in a dry p;ace over night. It could definitely be related to dampness in your phone.
My uncle bought a new phone so he gave me his old Xperia Z, which I intended to use as a secondary device
Here's the issue:
-The Z charges only when it is powered off, and that too very slow. Charging it overnight brings it from 0 to 65%
-I can't get my desktop to even detect the phone when it's connected either switched off or switched on. I see nothing in devices and printers
-I ripped apart an old charging cable and tried to charge it through the pogo pin slot (image attatched) it charges alright but that's the only way I can charge the device. Since I intend to install a custom ROM on it, I need to unlock the bootloader, and that's impossible without connecting to a computer
-Also when I connect a usb drive through USB OTG it just glows its led and does not blink it
I'd like to know what the issue might be and what are possible solutions
I think the problem is in hardware and the connections of one of the data pins of the USB port is broken.
I have a great problems: from two days my phone recharge, or connect to pc, only if is off.
If i try to recharge from wall adapter, or from pc (or connectiong to pc) nothing happens.
If a plug the cable to pc or wall adapter while phone is off, then i start the phone, all is right; but if i unplug the cable the reconnect it, it doesn't work and i have to shut down my phone again.
I tried multiple cables, 2 wall adapters, two pc both win10 and win7.
Now i am obliged to do that way: if a want to recharge, or to connect to pc for file transfer, i have to:
1) shut down the phone
2) wait the recharge process starts
3) boot the phone
4) never unplug the cable until i have finished what i have to do
I had LineageOS from 1 year; the same way happens in TWRP recovery, so i thought it was a recovery problem.
I updated my recovery, nothing to do; i updated Lineage, nothing to do.
So i returned to stock situazion, both recovery and Android, but nothing changed.
What can it be?
Thanks.
Ok thread closed, the phone is completely dead :'(
Hello guys
I recently changed from S9+ to S21 and I have a question : I usually use my desktop computer to charge my phone during night while I sleep. (with data USB cable)
I have no problem when the desktop is on (under windows) : my phone charge (with USB cable) and I can transfert photos.
When my computer is off, when I plug the phone, the screen show the charging screen for 2 seconds and stops
I have no problem with my S9 to charge when the computer is off. (I know that there is an option in the bios to keep USB charging when computer is switched off)
It looks like the USB power is too low, and the S21 doesn't want to charge with it.
Maybe ther is an option in the phone to authorize this kind of charging ?

Click to expand...
Click to collapse
There isn't such an option in the OS as of now. It's possible that the S21 battery amp requirements are more than those of S9
Do you think the computer's USB port has a lower supply when the computer is turned off ?
We don't know what kind of computer you have, or what it's USB port capabilities are. That's something you can try to figure out, looking at your computer or manual for the computer's motherboard. Also check the BIOS settings, sometimes you can control the power state of the computer when it is "off" and whether power is still supplied to the USB ports (e.g., to allow the computer to boot up when it detects mouse or keyboard USB inputs).
As an example, my MSI motherboard has a feature where you can install software to set the USB ports to a high power output state, so you can power USB devices using more than the standard output current.
My Dell laptop has a USB port with a special symbol that means it's for high-power output for charging phones etc. So it can handle charging modern phones, and puts out more than 0.5 amps, but only for those USB ports with the special symbol (lightning bolt).
You'll need to just find out more information about what your computer is capable of.
I have a MSI gaming pro carbon X370 ( the optional wake by USB is on, without that, you're right, the USB are totally off and nothing will charge)
I did more investigations .... I tried all my USB cables and all USB ports and finally find 1 combination that works.
Only 1 of 12 USB cables worked ( the one took from an external HDD ) even the original cable supplied with the phone didn't work and nor a 100W Ugreen cable...
And only the front USB work. The different USB directly on the motherboard doesn't work with this phone, despite I always used them to charge many devices...
for information the working cable is a KAIBAO revision 3.0
Finally it doesn't work with this cable : it take longer before the phone stops to charge, but it stops too ...
Hi,
You need to check the power requirements of your new phone.
Thank you.
