Well this is odd, happened overnight too suddenly.
The phone now only takes a change when it's plugged into a Samsung wall charger. I have no idea what could have happened, I woke up like I normally do, phone happened to be off. Plugged it into my normal cable which is in a hardwired USB wall outlet. Wouldn't start charging, the lightning bolt didn't go away. Tried different cables, nothing. Tried different USB wall outlets, nothing. Finally dug out a white Samsung white USB wall charger, plugged it into the same wall outlet the USB charger is built into, used the same cable that was plugged into the wall, and it started fast charging. I have never even seen fast charging before this. Tried different cables with the wall charger, they all work.
Things that no longer work also include plugging the cables into my USB ports on my laptop. The same white usb cable that worked with the Samsung wall charger wont charge on the laptop. Actually, now that I am trying it the laptop / phone doesnt even detect a data connection anymore. The lightning bolt on the phone shows that its plugged into some kind of source but I am watching the battery drain.
So what the heck could be going on? Samsung charger works perfectly and the phone charges back up but anything other than the Samsung charger does nothing

My phone won't charge from a mains charger, it will charge from USB (Very slowly) and an in-car charger but not from mains. I bought another charger just to check that it wasnt the supplied HTC charger being faulty, and that doesnt work either. When i plug the new charger in the wall the charger lights up, when i plug it into the phone it doesnt light up.
The phone will charge fine from USB and the car charger, but when the phone is turned off it wont charge from USB. When i got the phone i thought i had charged it from the mains for 4 hours like the manual said, but im now thinking that it didnt charge as i didnt notice the LED lighting up. I'm wondering if by not charging it properly the first time i have damaged the battery.
I just tried the mains charger for my Jabra BT headset and it charges fine from that, but only at USB charging speed. But it charges when switched off unlike USB. I'm wondering if maybe i have done something in Advanced Config, i have enabled all the power saving settings.
Does anyone have any suggestions as to what i can do and what might be wrong.
Totally stock (but i don't think it matters).
Plug the phone in, orange LED comes on.
Hold it or place in on the counter five seconds later, LED is off.
Had the phone since 6/4.
Anyone else having issues?
Are you using the AC charger ? I have two Evos and one of the chargers does what you are describing. The orange LED comes on and then goes off after a while and the phone stops charging. Does it on both phones, the other charger works fine with both usb cables.
Are you using the USB charger with a computer or laptop or plugging straight into the wall with an AC charger?
This does make a difference because if you are charging with a USB + laptop combination you could be suffering from the computer going to sleep and disabling the USB ports power to conserve laptop battery life. If you are having the issue when plugging into the wall, try plugging into a computer and selecting the "Charge Only" option when your USB debug comes up. Once it does this, allow it to charge for a period of time and then turn the phone off, switch to AC power plug and see what happens.
Perhaps you had some kind of over voltage spike on the charger through the AC plug. I could see it possibly tripping something in the phone to stop taking charge to protect the handset.
Also make sure if you do use a laptop, use a USB 2.0 or better port. More power and faster connection. Gotta love it.
Your charger may not be sourcing enough current anymore (for whatever reason). I have seen the exact same behavior with USB car chargers that were only sourcing 100-150mA.
Have you tried plugging the USB cable into a modern desktop PC? (Some laptops have reduced current ports, so a desktop is a safer bet)
Its definitely a current issue. I tried to charge my phone using my bluetooth headset's wall charger, but I got the behavior you are describing. The bluetooth headset's charger just doesnt put out enough current.
Are you using the charger that came with the phone? if so, you may want to exchange the charger...
im having the same problem when i connect it to my desktop, it sees it for about 2 secs n then disappears. My computer at work has no problem seeing the phone. i wonder if i need a driver or something for my usb ports, anyone have any ideas??

Probably not a driver issue, but that that rail from the power supply is either undervolted (say 4.6V instead of 5V), or can't provide enough current (amperage) or both. If I recall correctly, the Evo needs 5V @ 1A (+/- 3% tolerance).
Phone not charging
my phone has been charging fine since I got it... even been using the night desk clock app while sleeping at night for the alarm with it plugged in... everything was good...
With my phone about to die today, I plug it in to the wall charger, the led/batter indicator shows that it is charging... then POW.. it says I have a low battery and it needs to be plugged in... WTH??? it is plugged in!
The only thing I did today was flash the new boot.img for the cap fix over in Toast's thread...
Weird thing now is that I took my hero battery and put it in my EVO, plugged it into wall charger, and it stays charging... So, I put my EVO battery in my hero, plugged it in, and whola... it's now charging...
Please help as I am baffled.

that's your problem right there. that custom kernel is known to have charging issues.
I'm having the same issue with my car charger consistently. Plus my AC charger less consistently. For example, I'll go to bed and plug it in, the next morning I wake up and see the phone is at 80% charge and isn't charging. At some point over night, it gave up. This is with the stock charger too.
Hello everyone. I just want to start off saying that this is NOT a question about USB charging. I know about the trickle charge/lack of voltage stipulations. This is about the factory A/C adapter and USB cord I got with my transformer.
About 80% of the time I plug in my tablet to the A/C adapter, literally nothing happens. The screen doesn't turn on while in sleep mode like normal, the battery in the bottom corner doesn't change to a little lightning bolt, and most disturbingly, my tablet will not charge. The weirdest part is that it connects to the computer through USB no problem. I can move files and such, but no charging. Any ideas?
the charger construction is marginal at best and may need to be wiggled to get a good connection. also the usb connector an be plugged into the charger incorrectly. remember the usb connectot on the supplied cord does not comply s
with the usb spec. Also chev
ch the country ac side adapter ther are also unreliable
My cable went screwy and now it only trickle charges, regardless of what it's plugged into. I've got an RMA for it, but since I have to send them the cable to get a replacement, I'll have a paperweight for a few days at least.
Are you sure yours isn't trickle charging? There wouldn't be a lightning bolt, but I does charge.....very slowly.
Unplug the AC adapter from the wall for about 20 minutes. Plug it back in. Plug in TF.
Charging now?
unplugging it for a while seems to work better than anything. I'm pretty sure there isn't any trickling going on.
You can also try using the charger for your phone if the plug is a USB type. There have been a lot of problems with these charges documented in other threads.
Unplugging it definitely isn't a solution for me. When it first started happening I could do that and after a little while it would start working properly again, but now, it has charged at normal rates in about 3 weeks. I'm going to send it in with the RMA, but I have no idea what the turn-around time is. I'm going to be without any way to charge for that time, which pisses me off just a little bit.
When i charge my phone from a wall charger it charges perfectly all the way up to 100%. However if i charge it using my pc from its usb port using a usb cable it usually charges upto only 14% and then gets stuck at it, charging is also very slow compared to charging with the wall charger and i do also sometimes get random reboots when charging it with my pc using usb. So how do i fix this issue as i do not currently own a wall charger of my own and have to borrow it from my cousin
Problem solved
so i figured out what the problem was and now it's charging all the way upto a 100%.
instead of plugging the usb cable using a usb extension or on my casing's USB port i plugged it directly into the USB 2.0 port at the back of my mother board and it started charging normally again . no random reboots etc. So please close the thread
Backstory: My cat chewed on my usb cable while it was charging (stock cable and turbo wall adapter). Phone was off when i discovered it. I plugged in the chewed cable to test it out but it immediately shuts down the phone when i plug it in. Could this be due to a voltage protection from damaged cable?
I replaced the cable but now my phone wont charge on ANY wall adapter, nothing appears or happens when plugged in. But when i plug the phone into my PC it recognizes it and charges it (slowly). Any experience this charging issue?
Which wall adaptors have you tried charging with, and is this with different wall sockets?
Do other devices charge from the same wall adaptors okay?

I tried using the stock turbo charger and various other 5v/2a generic chargers. I even tried a friends Huawei stock turbo charger. My motorola stock turbo charger works on other phones so i know it still functioning
