What charge times are you lot getting via usb? For me 0-100% is 3days 19hrs but on ac it's 4hrs.
To me this isnt normal for usb as my HTC hd2 running ics was about 5hrs on usb.

I contacted Samsung and this is their reply
Thank you for contacting Samsung. I apologise that you have been unable to locate the requested information about your GS3, I understand this can be frustrating.
Inregards to your previous email, when you are charging your GS3 by usb with the phone switched on the power usuage of the GS3 is only slightly less than what the usb lead can charge the phone at so it will take longer to charge.
When the GS3 in charged by the mains there is more power running to Phone and will charge more quickly
If you require any further assistance, please contact Samsung again and we will be more than happy to help.
Kind regards,
Gavin

Basically not answering my issue as to whether the phone has an issue.
Try a different USB cable or charger.

I have tried two pc's and two cables and the same result with both.
If i use both cables with the AC charger they both work fine and as i mentioned is OP my HD2 running ICS charges to 100% in about 5 hrs where as the GS3 is nearly 4 days using same cables/pc.

hi,
i have an MDA Compact II of T-Mobile..
Previously it had German Windows Mobile 5 ROM, and I wanted to install an Spanish ROM..
Turned to be that the spanish one installed allright, but when i tourned the phone on it didn't... So i plugged it in and came to life but the battery was in 0%...
I let it plugged for half an hour but the charge didn't went up...
So i tried to install a new German Rom again but it doesn't allow me to do it because the battery is less than 50%...
I tried with several charmers but no one turned to solve my problem...
There is anything else that I can do??
Do you need mor information?? Tell me how to obtain it.. I'm preety new in this things...
Thanks
:/
There is a way,its a little bit extreme and i dont recommend it in any case but here it is if u like risking ur phones life: like battery flashing u need to connect ur phone directly to the cut off usb cable without battery,+to+,-to- all 4 wires, and the phone thinks that its backup power that ignores battery% but its still USB connected..I discovered that when i bought 3.6v instead 3.7v battery and it didnt want to start charging or start the phone if battery % below 6,so i did already explained and in the meantime little experimented. Its very low voltage on usb cables so it cant burn phone but u never know..
Like on picture connect usb wires to pins on phone those contacts go to..

Hope this helps..

It doesn't look like it to me. Is this true? This would be a show-stopper for me. Thanks.
Found the answer: No.

Well that sucks.
If it's any consolation, neither does the Xoom. I think once you hit the larger tablet form factor, you can expect USB charging to go out the window.
Yeah, 5V DC at less than an amp is only supplying around 4.5 watts of charging power. You're looking at 7 hours or thereabouts to charge via USB. If it's any further consolation, the iPad can charge via USB, but only high power USB or when it is asleep. It will still take a long time. Still, it would be nice to have the option even just to keep it topped off while near the computer.

Amen!
Anyway I find the overall battery performance on the G tab pleasing!
What about something like this?
I have this:

which is powered externally via 5V DC at 3A amps. It has USB ports on the bottom and even comes with a USB-to-DC adapter for the Sony e-Reader.
Since this isn't a regular computer USB port (I guess), could this type of setup theoretically work with the GTab and, if so, is there some type of USB-to-DC cable that would work?
My S3 has developed a problem with the battery charge draining. When i am charging my phone, either by USB or wall charger, the battery will charge extremely slowly or go down. This is while nothing running and left overnight to charge.
Has anyone else come across this problem? My phone has become unusable because of this and must be constantly plugged in. However, even when plugged in it will turn off sometimes due to running out of juice.
I'm leaning towards thinking that the battery is the problem not the charging circuits of the phone.
Try charging it with the phone off and if that doesn't work do a hard reset. Some of the custom roms allow you to adjust the charge rate as well, have you installed any custom roms or modified any of those settings?
If none of the above work then it is most likely a hardware fault possibly battery.

I find the SGS3 to charge MUCH faster than my SGS2 ever did.

I agree, I was charging SGS2 in my car and it would go maybe 1% in 30 minutes while BT audio streaming/GPS navi was on. Where as using the same charger for my SGS3, BT/GPS on doing the same thing, in 30 minutes it went from 87%->92%
I have flashed a new rom (CM9 nightly) and removed the kernel i had on in case it was that. Tried to charge it overnight and this was the result:

I bought another S3 for my friend at the same time and he has observed similar problems. It seems to charge partially when in the wall socket but into a PC is useless even with everything off.
I might have to get a new battery and try it out.
My beloved S2 has the following problems and they started from yesterday:
The phone charges fine but even when it is plugged out, it shows "Charging"

When I turn the phone off, it boots back into the ROM, not the battery symbol
I have tried cleaning the port with alcohol

I have exactly the same problem, the micro USB port of the device is damage, you'll fix the problem by changing it
How much is it to fix? Did you do it yourself and was it easy?
Try bending the contact pin inside your phone's charging port upwards with a toothpick. Cured the eternal charging on my s2.

Do I have to use a branded Asus charger to get the fast charge? I'm using an old Huawei one and I don't seem to get the faster charging as I did on my P30 Pro.
Looking to purchase a 2nd, smaller charger if there is a compatible one?
I guess any QC3 or PD charger should work.
Will this give me the fast charge I'm after?
PD3.0 PPS or QC 4.0 will according to Specification.
A friend of mine with ZF9 tells me that even with original Asus charger and cable it appears the "Hypercharge" text on the phone, but the real charging speed is slow; anyone else with the same issue? Thanks!
most battery management will only charge fast when the battery is almost fully drained, generally following this curve. You'll see like 5W or something when closer to 90% battery, even on silly charging protocols like SuperVOOC. https://www.androidauthority.com/fast-charging-explained-2-889780/

I know this, is not the first phone with fast charge that I see, and my friend too is not so noob.
So, the problem appears on his phone even with battery on very low percentage.
