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.

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.
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.
Hey
Has anyone brought one of these chinese knock off charging dock. My unit didnt come with one so I am considering to go for one. Most of these are under $10.

Okay I have to admit that isn't worth the money.
Which one did you get though???
Sent from my D6503 using XDA Free mobile app
something like the first one.
but i really wonder WHY it does that!
I mean... i used the original Sony Wallcharger! 1.5A and just pluged it (with the sony cable) in the back of the charger!
Then the phone wen't out of battery and died... restartet after 5 minutes, and then i booted into the OS.
Thats the only reason i can imagine why it would charge so slowy. i mean.. i used exact that same wall charger via microUSB and it worked fast and fine!
i mean, how the hell would they limit the Ampere flowing trough the dock ? some included resistors?
If i have to much time i'll try and open it. but i could swear the cheapest way would be a simple (two...) from the microUSB port to the magnets. And this is chinaware! gotta be the cheapest way!
The S23 Ultra is sometimes charging Super Fast 2.0 and sonetimes normal charging with official Samsung 45W charger. Also there is no option to enable Super Fast charging in battery settings. What is your experience?

If I have to guess I think it switches between normal, fast and super fast according to device temperature. High battery temperature could damage it. By the way 45w and 25w probably charges very similar on this device. Maybe 10 minutes diffirence on full charge(if I remember reviews correctly)

You are right i think ites temperature based. In car when my phone is hot, its chargeed only few percent with 60W samsung charger L5300.,
So after one ui 5, fast charging enables the super fast charging if your charger supports it. Also it will only show you super fast charging 2.0 for few seconds when you plug in your charger and the text will switch to charging but the device super charges. Hope this makes sense.
