Hi all,
My friend's OPO does not charge when connected to the USB port of a computer. It is stock, unrooted, KK 4.4.2.
It charges fine when he charges via the wall charger. My OPO charges fine out of the box, with USB on the same laptop and port.
He does not want to factory reset and I am at a loss here. Please advise what I need to check here.
Thanks!

He can buy a universal adapter for the charger. They're pretty cheap.
It's because the laptop isn't putting out enough current. It must be at least 2a to charge properly.

The issue here is that my OPO charges through the same USB port and with the same cable. That's what has me baffled.
Well consider me baffled too.

Anybody has any idea about this issue?
The front panel of my pc case has usb ports that has trouble recognizing or charging any phone. When I plug it in, the phone will show it charging but the battery continues to drain or I can't access the sdcard. Not sure what causes this, but when I plug my phone into the usb ports in the back that are connected directly to the motherboard, then there is no problem.

Thanks for the reply but that is not it. My OPO charges fine from the same port and the same cable.
Anybody got any info on this issue?
Uh, I'd say factory reset or don't worry about it.
Not sure what you expect to hear. But that's probably the first plan of action. Especially since yours works fine.
Opo has higher power requirements. You may need a cable with a 24AWG or better rating (lower allows more current).
Does it work with the stock cable?

My OPO works with any cable, though time to charge is the best on stock cable. But my friend's OPO doesn't charge at all. Even on stock cable.
Unable to make sense of it at all. I may sound like a simpleton, but maybe there is some checkbox I ticked somewhere which is preventing this? UGH!

The phone will work with any cable. Worst-case the cable's resistance and diameter will reduce the maximum charging current significantly but it always will charge the phone.

No USB port has that much current except maybe for highly specialized ones. USB2 is rated on 0.5Amp, USB3 on 0.9
Of course the phone will take significantly longer to charge or may even discharge when used while plugged in.
I can say "me too". My one also didn't charge from powered off PC while Nexus 5 plugged in the same PC with same cable charges fine.
When PC is powered on, One charges intermittently. I.e. I plug it in, it charges for some time and then stops. "OS monitor" shows "discharging [USB power]" state.
Any thoughts?

Cannot charge OnePlusOne via USB
I have the same problem.
The problem seems to have started AFTER upgrading O/S to Cyanogen 12.0.
Cannot charge via USB either from my note PC or Mobile BatteryPak (1.7a).
Above comment that 2a power is required is surprising, as I thought 1a is standard. Maybe there is some Cyanogen bug here?
I found in some Forum to make of SETTINGS - STORAGE - USB COMPUTER CONNECTION, but I do have this setting, and still cannot charge the computer.

It will charge very slowly but will charge faster if the device is off. If you're using it while it's charging it's like filling a bucket up with water that's got a hole in the bottom. It fills up. But slower than it would if there was no hole.
As for the battery pack I have a 2.0a EE Battery pack and it works fine so it might be related to the analogy above.
Sorry to bring up an old topic, But its still hanging and non has really come up with solution. So i thought let's bring some light to it.
My dad has encountered the same issue the other day, I'm basically not much PRO into fixing things like this but by turning on/off USB debugging while connected to PC and also turning on/off Developer options does makes it charging through PC again.
Previously it was charging by PC, but dad has messed up something internally and asked me for help, so this lil so called tricked work for me. I hope this will help others to.

Is this normal? cant get it to charge while connected to my usb port?
It says it is charging in the power options, but can be on all day, and as soon as I unplug it its saying no battery left !!!
Also has the been an official rom update yet?

Hi, You don't have the box ticked in the battery screen do you ?
the one that says
When device is turned on, do not charge the battery when connected to the PC
this should be unticked.
dean
Hi Dean
Now I dont have it ticked !!
Any other idea's?
The problem could also be your usb line or usb port. try some alternatives first.
Tried everything, different usb leads, different sockets even different laptops !!
Help
Same problem here. But i changed the USB cable and problem solved. Did u tried it, with the official USB cable from HTC? (I guess so, just to check)
Yep I did !!
Will try again when I get home though..
Thats strange... my TP came with UK power adapter, so I couldnt use AC power until I get an adapter (4 days)... in these days I always charged via USB (all night long)
Well I tried the official usb lead and it charged last night, Im now using the official lead again using same laptop and same usb port and guess what !!! It wont charge again
Have I a faulty touch pro?

Hi,
this is sounding kinda weird..
What kind of wall charger came with the phone, mine is a wall adapter that i plug the USB lead into to charge the phone
So i know my USB lead works as this charges the phone with both the adapter and via USB on any PC ( i have tried home and work PC's)
Sounds like it could be a handset issue then ???
mine is a Vodafone handset that i bought unlocked and flashed with a different ROM and its working fine..

Laptops can be a bit funny about USB charging, I remember one laptop I had wouldn't charge my phone (SE K800i at the time), unless it was on mains power. The laptop had to be powered up while on the mains, with no USB devices plugged in, then it would supply power to the ports.
My work laptop is also a bit funny about it, I had to disable powering down of the USB ports otherwise it won't power them back up, but since if nothing is connected there's not much of a problem. There is also the possibility it's powering the port, which will charge the phone, but not enough power to actually make it worthwhile, you can check to see how much power is going to the ports by looking under device manager. So you might want to check it's not a problem with your laptop.

This is exactly what mine turned out to be. At work I've got a Dell Optiplex 745 tower and none of the USB ports put out enough power to charge my phone and have the phone on. I've got wifi turned off but the data, EDGE, is always on. If the display is on and I'm in Storage mode there's very little charging going on. It doesn't drain quickly but it definitely isn't going up. If I'm in sync mode it drains pretty quickly and it seems as tho it's not even charging at all.
What I do now is plug it in at work and turn off the display. Kinda sucks but I need my phone fully charged at all times.
I have the same problem....
the usb and the factory usb are different if u have looked carefully
firstable, the shape of the heads are different. secondly, there are 4 pins inside usb and 6 pins inside the factory usb...I guess that's the problem.
Try messing with the USB to PC settings. I know my TP was acting funny and not charging, and after i disabled network functionality, i think it started charging. GL.
Thamks for all the replys, if done everytjhing sometimes it will charge sometimes it wont, I have it connected to my laptop all day for internet sharing, it has charged up very slowly twive, and not at all 8 or 9 times, same usb slot , laptop plugged into mains, official usb lead used ( it never charges from another usb lead )
This is the 3rd htc Ive owned and the first to play up like this over usb !!

Have you tried it plugged into a desktop computer? It would rule out the laptop being the problem if it didn't work. You could also use a mini-usb cable, which could also prove if the official cable is a problem.
Having similar problem...
I'm having a similar problem. My laptop used to charge Touch Pro when i connect it. Now for reason i noticed that it doesn't anymore.
I could be wrong, but I thought I read in the manual that when the phone is synched to a PC, it only charges in trickle mode, so it doesn't recharge the battery efficiently. Is this the problem?
same problem here. Mine was working fine with ANY charger whether it be USB, car charger or wall charger. But now it will only charge with the htc plug but not the HTC wall charger. The plug is the one with the ports for tv-out, headphones.
I'm going to go try and do a hard reset.I dont understand what could cause this.
HI,
does the i9000 Galaxy S support the quick/fast charge from battery charging spec. 1.1?
My new pc mainboard does support this via software/driver. And allows to load with up to 1,5A
I couldn't find information on that.
The i9000 is USB 2.0 not USB 3.0, so the answer is no.
not exactly correct
as it does charge faster with a higher AMP output charger.
i use a 2 Ah or 2000 mAh charger in my car and the phone does accept the faster / quick charge
so if your PC has the option to do the higher 1.5 Ah output, it will take it just fine
just like if you have a 1200 mAh wall charger as some people here uses.
I installed the asus driver which installs a service and the aicharger.sys
I restarted.
They tray shows an icon with a plug, but it is crossed. Like disconnected.
I pluged in the i9000 via the usb2.0 port an no changes.
I then pluged the phone in to a usb3.0 port but the icon still shows disconnected (or ai-charging off)
Any ideas?

This is the bit that is not exactly correct. Regardless of how the hardware is set up it's up to the phone driver to request a powersupply from the computer. As it is the Galaxy only requests only 2 unit loads (200mA) from the computer, no where near the 500mA max of the USB2.0
So no simply plugging in a more capable computer won't change a thing.
interesting.
Are there any mods or fixes to support more usb power while connected to a pc?
None that I have seen.
ok, so the only possibility to charge faster is, to get an after market 3rd party wall plug with higher current than 700ma?

Interesting. So does the SGS actually use all of the 700mA out of the stock factory charger? If I use my 2.1 A charger could I overheat the battery?
Ok I've had it with the speculation. I've got a USB micro socket and plug on order and I'm going to make a pass through cable and measure the 4 different chargers I have here at the moment this weekend so we can put this one to rest
Stay Tunes.
Ok did a test. No the SGS does not use all 700mA. It uses 470mA. Charging is faster from the dedicated charger than the computer. I verified that the phone only draws less than 100mA from the computer socket.

Thank you.
But can I get more current from my PC with ASUS ai Charge?
I installed the driver but the icon in the tray doesn't recognize my Samsung.
That is because it doesn't have something an Apple Product has.
Apple products get more current with that driver/software thing. But the i9000 doesn't work with it.
in the past i checked if it is possible to charge the battery faster, and not Necessarily through the phone.
i asked a guy who works with electronics and he simply explained that everything is possible, even charging the battery to full in a few minutes, but it WILL kill the battery very fast...
yeah i installed to anticipate a quick charge...but all i get is icon with a big cross...
deleting it now......its useless to me...

Everything is possible when you charge the battery itself directly, but not when you charge through the phone. The phone is the charger. The computer and the wall plug only provide power to the phone. Unless you go in with a soldering iron there's nothing you can do to speed up the charge beyond what the Samsung wall adapter gives you.
Hi guys, so I have a stock N5 and it won't charge over USB or AC unless the phone is turned off. I've tried to factory reset with no luck.
My current theory is that something's up with android itself, instead of BIOs. Has anybody else experienced anything similar to this?

when I first turned on my N5 and connected it via USB to do various root related stuff, my battery actually went down with each reboot. Even connecting to the AC cable charged it pretty slowly. But now it's charging fine via USB or AC (although the charging speed with USB does seem a lot slower than my previous phone, Galaxy S3)

Yeah, the phone charges over AC slowly here too, but strangely enough it won't even make a USB connection with a computer as your phone did.
Same Problem!
Hi,
I'm having the same problem.. I could use it well and charge it over USB nicely but know it only charges when the phone is turned off. You could solve the problem??
The battery pages says "USB" instead of "AC" when the charger is connected which makes charging very slowly
The problem exists after upgrading to 4.4.2
Is there any solution?

From my understanding the difference of USB and AC charging is the Amps that runs into your phone. I'm not sure what you mean by 'charger' as for me I also use an external charger like a backup battery. If you are referring to a wall charger then you may want to try another charger as this may mean that that charger isn't providing enough Amps to your phone. If you are using a external battery to charge your phone then I would think it's because of that particular external charger. Some only charge at 1A--mine charges at 2.2A--which may trigger a USB charge.
Haha, look, I'm NOT a pro. Nowhere near even. Just chucking in my 2 cents for the purpose of experimentation.
Android determines that you're on an A/C charger by the USB data pins being shorted together. If they're not, or if they're missing entirely, as is the case with a lot of "charge only" cables, then it will only charge in USB mode.
For A/C mode, you need an android compatible charger, and a data cable (not a charge-only cable).

My phone can transfer files at normal speeds in bootloader mode. It can even transfer files fine when booting up to kit kat. the issue is even though it does all I mentioned, it won't charge (or charges too slow to matter) via USB connected a PC or USB to any AC adapters. I've tried many working cables and AC adapters, could someone please help or point me in the write direction?
NOTE: It on occasion charges normally.

If it on occasion charges normally but not all the time then perhaps you have some internal damage at the charge port. Now I have no idea how to fix this but one other possibility you could try with the Nexus 5 is to get a wireless charger and see how that works out for you.

trying a wireless charger right now, same old game. slow charging still. I did notice the battery readings with Ampere, i attached a screenshot. the temp is negative -30 celsius on average often show a negative charging status no matter what charger is plugged in and EVEN with a wireless charger.
Does this mean I have a bad battery?
I'm afraid your guess is as good as mine at this point. I've never experienced that type of problem. I have experience of damage to the charge port with an old nook it behaved just like you said which is why I suggested wireless charging since we have it available on the Nexus.

yea, i bought a wireless charger to no avail. something either within the phones board or my old AC adapter had gone wonky, put a new battery in and the same thing began happening after 2 days.
