So I went out and bought a 2nd USB cable to leave at work to charge my phone. But for some reason the USB cable I bought doesn't charge the phone...instead it drains the battery..??? The light is on and the icon shows it is charging when I have the USB cable connected and I can even mount the SDcard with it. But the battery percentage slowly goes down. The USB cable that came with the phone works fine without any issues.
Is there something special about the stock USB cable? Do I have to buy a certain type of cable to make charging work?
I bought another two cables, even used a Motorola USB cable but never noticed that... it never happened to me.
My guess is:
Fact:
- charging through the pc USB port is so slow, to get full charge you need 6-8 hours compared to 1.5-2 hours through the wall..
Scenario:
You are using your phone or running heavy application while charging it so it drains more battery than charging ..
Just a guess.

Phone discharges and does not charge when ON and plugged in.
The charger light glows even if it is jst connected to the phone and not to the power socket. Though the charging seems to work once the phone is switched off but jst charges upto 10% after which the animation turns blue and stops charging further. , also if trying to charge with USB via PC it says unrecognized device and the phone doesn't charge.
any solutions?
have tried different USB wires as have a cpl of more Androids at home but same issue with all wires.
I am using pure stock rom with no rooting or flashes done yet.
There was a solved thread in forum but for other rom.
Hello, my Huawei y300 (u8833) only turn on and works while I plug in my usb cable either (charge). My phone doesn't turn on when i press the power button and I'm on just my battery, amazingly it turns on instantly after i plug in the usb charger and remove the battery. So i got a little tired of having to plug in my phone all the time and not use it on battery. Any help? I dropped my phone 9 months ago and it didn't work back then but i never tried the usb cable on without battery. But now after 9 months i plugged in usb cable and no battery and *boom* it works. Any advice as to what is going on? Can i ever get it to work from my battery? (BTW there is a red notification light (not blinking) if i put battery in along with usb cable. Thanks for any help.
Update: Somehow its charging my battery!
Update: (PS:I'm rooted and have cwm)
Update: I'm fuc*ing stupid, its now working on battery! Sorry to have waster your time
Ok so I started having a weird charging issue with my Xperia Z2, a few months ago when I plugged the phone in to charge and noticed it was constantly showing it was charging and disconnecting non stop (basically this here Xperia Z2 charging disconnect)... first thought was maybe my usb cable (original Sony cable) was buggered but nope, plugged in my Xperia Z5 on the same cable and it charged fine, so I tried my magnetic charger on the Z2 and nothing, no charge at all. Eventually when the phone died completely then I was able to get it to charge but not without some issue, when plugging in it would still do the same thing, charge and disconnect constantly, it would take unplugging the cable and plugging it in again a few times till the phone would eventually charge and even though the charge would show 100%, when I turn the phone on, the battery percentage would vary anywhere between 80%-95% and it would discharge very fast.
I figured it may have been my battery as I have been using the phone with an expanded battery since like 2020 and thought maybe thats it for the battery. Eventually got around to getting a new battery this weekend and the phone still does the same thing but its a bit different now, connecting it with my Sony cable still did the same thing when connected to the wall charger, charge and disconnect constantly. Then I thought maybe it could be a software issue so I connected my phone to my PC using a different usb cable to copy some stuff to my PC before resetting the phone to see if that helps...connected it and it was charging...so I take my Sony cable and connect it to the PC with that and it was charging...unplugged the cable from the PC and plugged it into the wall charger and it was charging and disconnecting again. Plugged it into the PC again and started charging. Tried the other usb cable with the wall charger and it did the same constant charging and disconnecting. I know the wall charger is working fine as I am charging other phones on it too with no problems.
I try a third usb cable on the wall charger, this is a real cheap low amp cable, my Z2 starts charging with it almost normally, painfully slow but it was charging. Now I say almost normally because when it charges to around 90% then it starts doing the constant charge and disconnect again. Also the battery doesn't discharge as fast as it was doing before but still a bit fast.
I want to try flashing a new rom, stock and custom to see if any of those might work.
Would any one have any idea of the issue or experienced anything similar and was able to fix it? Any help any one
In the past I had a similar problem, try to clean the Usb port on phone and try again.
Kindly regards
I remember reading something about the live kernel being involved in charging. It makes sense for this to break charging while completely empty. To charge at full speed you need the kernel to be running, but to get the kernel running you need power, the trickle charge you get without a kernel isn't enough to keep up with the boot process, so you end up in a loop of no power. I have not tested if another kernel fixes it, but it is currently broken on my device.
