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.

Greeting to XDA-community.
I have a problem. I don't have any opportunity to use regular charger for my G1. So I used charging via usb, but when I have turned on Wifi (ad-hoc to connect with laptop) and started to use G1 heavily it just dropped dead (battery is 0%). As I understand charging via usb is less then amount of power G1 uses during heavy use. But now I can't charge the phone at all. I have killed my second battery (stock too) the same way. The only thing that I see when connect to usb is that LED is red, sometimes light is pulsating, but can't turn the phone on. I also use to different source of charging. The problem I can do this only from USB port . Did somebody have such problem? I need someway to charge it...
Thanks for any help
You could try a powered USB hub, but if youa re going to buy something, why not just buy a charger?

I am using smth like this, a charger for mp3 player with 5.2v. Doesn't help
I am in Europe for couple of weeks, charger isn't working here due to different plugs, so I didn't bring it with me (but should , you can buy adapter US-EU plug without problem), thought charging via USB is working well, but it don't.
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
Hello,
I just got an external battery and tried using it with my phone, but it refuses to charge from one of the provided cables and enters USB host mode. On the other hand, if I plug in another of the provided cables it starts charging right away as if it was connected to the wall charger.
For reference, this is the battery I got: Genius ECO u306 (http://www.geniusnet.com/Genius/wSite/ct?xItem=58540&ctNode=3633&mp=1). If you look at the 3rd photo, you'll see an attached (red) cable hanging out. That one fails to charge my One, I also tried it with a Galaxy S5 and got the same USB host mode message, but when I connected it to my old Xperia X10 Mini Pro it charged normally. The battery also has one full USB and a micro USB port, and when I connect a cable from the full USB port to my phone (or the S5) it charges normally.
I got this battery so I wouldn't need to carry an extra cable with me, so it would really be great if I could disable USB host mode for this device, or when I want to use the battery. I also don't want to disable USB host mode completely, because I use my flash drive (OTG) with my phone from time to time. Does anyone know of a way to do this?

In case it matters I have an unlocked (and rooted and S-OFF) WWE One, with ARHD 53 (Android 4.4.2, SENSE 5.5), firmware 4.19.401.11 and TWRP 2.6.3.3
Hello. I have quite the issue, the phone's MicroUSB has seemed to stopped working. I remember one night I plugged it in the laptop to charge it and got an windows error, like the port failed, but I was too busy to handle it so I left it like that.
I should mention that I used that option "Usb fastcharge" from kernel.. Is it possible my port is broken? It won't charge now at all.. I tried different cables to no avail. Previously I had to move the cable into socket and I could get it charging, but now.. nothing.
If I plug it in the laptop, I have the monitor attached on HDMI and for some reason it disconnects the monitor while I have the phone plugged in. Also it changes the laptop's brightness while I have it plugged. Seems so weird, I don't have warranty on it.
Also if I simply leave it plugged into the wall charger/usb port, the phones MicroUSB just heats up. I get no charging indicator or anything.
Anyone been through this?
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 ?

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.
