You have exactly my problem. Your usb controller is burned and it can no longer charge with 4-5 volts. It needs more. I can only charge my phone with QC-3, which outputs 8-9 volts, but your rom must support higher than 5v charge. You also won't have any access to PC, including fastboot. And unfortunately, to fix the issue, you will need a new motherboard, which doesn't make sense unless you are on warranty.

You can probably install one of those stock roms that includes older firmware (look for official TWRP installable roms on europes fans forum). That should lock your bootloader. Just be careful reading description and directions.

[Q] Charging problem & question. please help

Well I have bought a rooted ONE X . Previously locked and bootloader unlocked by owner. I dont know so much from the world of android development so i have so much difficulties. I dont own an original HTC wall charger. So atm i am charging it from the pc usb port. It takes about 7-8 hours to fully charge... I bought a Samsung charger which has 5v---1A output power. And it charges my phone for much more time than the pc usb port. That made me order an HTC Authentic charger and cable.(hasnt arrived yet) Will that solve my problem and charge faster? Or is that a problem on my phones firmware?
Second question: If i factory reset the phone will it get relocked? (remember it is rooted)
Im waiting for a reply.. thanks
bump
You can relock the bootloader by going to fastboot and plug in the phone and enter cmd, type fastboot oem lock. In general I have noticed a slower charging rate via usb as well. I think from wall is faster. Why would you want to lock the bootloader though? This doesn't sound like a software problem and the bootloader is the last thing that would cause slow charging I think. Root access is the way to go imo
Sent from my HTC One X using xda app-developers app
A wallcharger is much faster then a usb port indeed. Via usb you charge only half the speed, unless you root it and use a custom kernel that supports fastcharging via usb. That means it will charge just as fast via usb as with a wall charger.
And a factory reset will not relock the bootloader.

Why does that happen with a samsung charger? It has same output values as original HTC one.. It charges so slow on 5v 1A output power...
Well some phones just need their original charger/cable......i experienced it while flashing boot.img files. Using a non branded usb cable gave me okey flashing but the kernel didn't stick well and connection was not optimal. As soon as i used the original HTC cable all was fine. Can't really explain

yeah i did that but still nothing
the battery drop sounds like a clibration problem - coupled with a possibly loose usb port? Had usb charging problems once but got it sorted out by trying to plug the usb cable into the port from "different angles" (carefully!)

You need this tool to find out which one is at fault:
http://www.ebay.com/sch/i.html?_fro...&_nkw=usb+current+and+voltage+tester&_sacat=0
Swap one by one: charger, USB cable, USB port until you find the problem. Make sure to use known working charger, cable for testing. USB port flex cable is not expensive, just around $5 to $9 on Ebay.
You should have ~ 5-->5.2 Volts, 1.5 -->1.7 Amps when charging. Anything lower than these readings, you have a problem with charger or cable or USB port.
You have to use elimination method to find out the problem as there are many unknown factors when battery is not charging.

Phone not recognizing AC charger

Hi
I've been having a problem with my G4 for the past few days,
when i connect it to the wall charger it recognizes it as if it was charging
via USB not AC as it did normally, and when i connect it to my laptop it charges,
but won't let me use LG Bridge nor LG UP , and im not able to browse the internal memory
I've tried using several chargers and cables in several combinations with the same results ,
it only charges as AC with a no brand 1000ma charger that i had lying around and whatever usb cable i put on it.
is it possible that the usb on my phone is broken? or could it be something else?
already did a 3 factory resets and tried to flash a diferent firmware
but that's how i realized it didn't work on my laptop either.

and are the drivers installed? was it working before .? weird thing is you said it doesnt worked in another PC. make sure drivers are installed and i guess the usb cable could also be the cause.. it has happened to me that it wont recognized to transfer files. only way i solved was reformatting my Pc install drivers and voila.. but first make sure as its not working in anothe PC.
just tried on a third computer and nothing
all computers have drivers installed, tried several cables, i don't even care about connecting it to a computer
i just want it to charge normally with an AC charger

i tought you said it charges, but you cant browse files . then it must be something wrong with it. i guess send it in for repair or contact your retailer. or carrier.

yes if i connect it to a charger or to my computer it charges,
but when i connect it to an AC charger it shows up as charging as if it was connected to a USB port
so this makes it charge very slowly , taking hours to charge with a 2.0 qualcomm quick charger instead of a few minutes
when i connect it to any computer it charges but i can't browse files or connect using any software
i tried using several chargers , the stock charger that came with the phone, one from a G3 , a QC 2.0 charger, several samsung chargers, and others and only one shows as AC charging.
so yeah it charges but not as it should

did you tried ampere app from PS. so you flash back to stock using stock firmware. and samething. what variant you have.? its very weird. but the best thing to do is if u are under waarranty send it for repair...
my story its different. i have original charger.. i use ampere app adn measure and its a 1.8a stock G4 charger, when i use another Lg charger i think its 1.2 i get more voltage with the 1.2 then 1.8 i switched usb cables samething.. very odd too.

i have had the same issue i have been able to solve it (luckily i am trying to update to mm via lg bridge it gives an error after which my cell doesn't show on pc neither it charges as an ac via wall charger so heres what i did)
you need to do exactly as described
1: connect your cable to wall charger(mounted to socket=on) and mobile
2: turn off mobile(do not unplug cable until mobile completely off ~10-15 sec)
3: unplug cable after off
4: press power button and than insert cable (within 4-5 sec)
5: let it start (it should b on AC charging)

only way is to take it to telcel and have it fix. or search i have no idea.
just as an update, i took the phone to my carrier, to make a warranty claim, see if they could fix it, they sent the phone to LG and returned to me, said as i have the camera lens glass broken the warranty was void and they wont perform any repairs on the phone as it was cheaper to get a new phone, also they didn't tell me what the issue with the slow charge was, im under the impression that they only saw the shattered camera glass and said F**k it
im not sure if taking it somewhere else and replacing the usb port will help somehow

Lenovo K8 Note Battery Charging Issue (Showing charging over USB Error)

Hi all.
i bought a lenovo K8 note and also it was working perfectly and now i have a problem in charging.
its already providing a turbo charger with this device. since before two day i connect OTG on my phone and after that when i connect charger all are showing charging over USB and its deadly slow to charge my device. it takes almost 9 to 12 hour for 0% to 100%,
i tried changed cable with new 2.4A fast cable. try with USB 3.0 Ports, Try With Wall mount Chargers 2.0 AMPS, 3.5Amps etc.
I reset the device and also i am flashed my rom with 7.1.1 (Stock ROM). nothing was helpful. still now my device showing Charging over USB while charge with any charger on battery screen. deadly slow to charge up device (almost 12 hour need to full the battery before it was 3 hour maximum time)

I am having the same issue
I was try to change the all are like charger, cable, etc. But nothing was helpful. Basically i am a electronics tech. So I just bypass the charging Lines directly to battery with a suport of and diode.
After that it was much better (but can't see the percentage while charging)
Now I sell the product to some shop..
Now happy with asus zenphone max pro m1
In my finding i got a Final report.
It's battery response issue..
The battery have turbo identifier inside. T+ t- mark ups. (I removed back cover and checked all)
You can see the turbo controller in battery.
Maybe if you are in warranty quickly visit services center and ask for battery replacement.
Have a good time ahead.
Admins This thread is now resolved my self. So please close this with my solution.
Thanks.

warp charging issue

Warp charging doesn't go beyond 3.5Amps on ampere app causing slow charging rate shouldn't it give close to around 5.2Amps charging speed? Can anybody share their screenshot or is there a issue with my device

With Warp Charge there are several factors that come in to play. The charger itself, the USB Type-C Cable and your device.
Has Warp Charge ever worked on your device?
When the cable is connected do you see "Warp Charge" displayed on the screen?
Did the Ampere App ever show the maximum 5.9 amps or does it always show a maximum of 3.5 amps?
Are you using the original Warp Charge wall outlet adapter and original USB Type-C Cable?
If Warp Charge was working before, how long has it been since you last saw it work?
Have you modified the device at all?

Yes it was all working before I have earlier got 5.2 to 5.5 amps but from past couple of months it's been fixed at 3.5 amps now, and yes I have been using original warp charger provided and no haven't unlocked or rooted my device, could this be a problem with the device or any other fix for this?

Bought mine 2019-12 . few days ago (2020-03-30) warp charge stopped working, it still charged, but extremely slow like 40 percent an hour. When it was off i tried plugging in charger, but it started looping, it didn't boot to an animated picture with charging battery, but it still could boot into OS when power button was pressed. Did a factory reset, didn't help. Connecting to pc usb still recognizes it. Had a feeling it was a hardware error. Maybe fast charging module went bad.
Sent it for a warranty repair, got an answer that it will take more time because it was sent for an higher level service. I guess it's quite bad, it could be a motherboard fault.
I read on oneplus forums that quite a few people has a same issue.
Connect it to a pc, see if it is recognized. Mine stopped working & it was a bad USB Car port. It would still slow charge but no warp charge & no windows pc would recognize it connected
Hi! I have the same issue, only difference is that mine is sometimes charging at warp speed and most of the time at 3300 mAh "dash speed". Did you manage to see what the issue was?
