Faster USB Charging?

I remember on my WinMo phones there was a program to speed up the charging through a USB port. Anyone know of a similar app, hack, what have you for our Heros?

all that ever got me was an overheated phone. and defective batteries

you could try a wireless charger, or use the normal wall charger or get a 3rd party battery.
I use a 3rd party battery, and my phone charges from Dead, to full in under 2 hours. i think my brand battery is a radioshack one but i dont remember, and im too lazy to look lol

If the phone detects that it's hooked to a USB port, it'll charge more slowly because the typical computer port will only output 500 mA. A wall charger typically does a full amp.

No thank you, i dont need something else to carry around. I work next to a computer. it just sucks that if my phone is near dead in the am when i arrive to work it will have to be tethered to the computer most of the day to fully recharge.

yes, thank you. i know. that's why i am asking for a program to trick the device into believing its always the wall charger while its plugged into anything with that program running.

There is no point in "tricking" the device to think it's the wall charger because what you want is the phone to charge up, not to beleive it's charged up when it's not. The usb port will not output more than 500mA. The phone will only charge as fast as 500mA will get you, no matter what tricks we try to pull on them.

Actually, most USB 2.0 ports can unofficially support up to 1000mA (which is indeed out of spec), with the only limitation from the device itself which when in spec will not draw more than 500mA. This is why no2chem's Fastcharge worked on WinMo phones, by increasing the maximum limit on the device.

I don't know where you're coming from, but the phone will indeed pull more current when it detects it's on a wall charger. I specifically remember seeing it in the manual.

Has anybody heard anything new on this matter, I really hate not being able to charge at 1A from a computer USB anymore. 500mA is pretty much useless, especially in constant usage, it pretty much just maintains the current %.

from less than 10% to 100% in about 30 minutes when plugged into the wall...turn your phone off while charging!! itll charge so much faster!!

This was specifically about usb....

I seem to remember hearing you can tweak some usb wires (I guess remove the data pins) so the phone thinks it's on AC but I'd want to have connectivity as well as the swift charging. Otherwise I'd have to have two cords on me, though I wonder if the phone charges "AC speed" while off (since there's no mind to talk to the PC's OS)

I know this does't work, as I have a cable with no data pins (it's a cheapy charge cable only) and it's still slow on a pc to charge.

Get a USB 3.0 port.

I have a belkin travel power surge protector with 3 outlets and 2 usb ports on it. The phone, when plugged into it, doesn't detect that it is plugged into AC power and just charges at USB speeds. Anybody know why? Will it only charge at AC speed if it detects the HTC supplied Ac adapter?

I have a cheapy cable too and that might be why it's still slow. I don't use the cable anymore because my TP used to charge at like 200mAh with it.

But the problem here is with the software not hardware lol, all someone has to do is change the value of "when connected to computer: Charge 1A" instead of "when connected to computer: Charge 0.5A" (simplified of course)

Because it was a stupid idea to ever limit the charge speed. lol

Charge tab 2 via usb!!!

As we know that we can not charge tab 2 via usb when connected to pc.
But there is a way:
do not insert whole usb to port at once.slowly insert the usb(connected to tab) to port(of pc) upto its approx 1/2-3/4 portion.you will see charging symbol on tab battery icon.it may take some time to figure it out.but it works.....
Note:it works on p3100 for sure and may work other models.
ENJOY!do not forget to hit thanx button...

a video demo how to do this should help :cyclops:
it works! thanks for the tips

I wanted to add a clarification: when plugged into USB the notification popup indicates "discharging". But in fact it is charging, because the % charge goes up (slowly) with time.
The trick mentioned in this thread may make the tablet show 'charging', but I doubt that it makes any difference to whether it is really charging or not. The charge rate is determined by the max amps of the charger. The supplied Samsung charger is rated approx 2A; if you use the USB from the iPhone charger it is approx 1A (if you have USB 3.0 ports, that is also about 1A); but USB 2.0 gives you only 0.5A.

As said...charging over USB is painfully slow (2,5-5W). I prefer to charge it with the original adapter (10W )

The tablet or phone will sense if the connection to the charger is AC mode or USB mode, if AC mode is detected then the tab will pull up to ~2.1 depending on the available rate from the charger, if USB mode is detected than the tablet will only draw ~0.5A.
The way the charger is configured will let the device know if it is an AC mode charger or if it is an USB mode charger.
By shorting pins 2 and 3 together on some chargers/cable the device will detect AC mode and it will pull more current.
I have a 1A 12V car charger that was wired for USB, an android device will see it as USB and pull only 0.5A, but an Apple device will pull the rated 1A. I shorted pins 2 and 3 and now android devices pull up to 1A, I am not sure but I think it is no longer compatible with apple devices (I don't own one).

It will say that it's not charging when plugged in via USB, but if you have it plugged in, it will charge, slowly. It takes forever if you're anywhere close to having a dead battery, and if you have wifi and other stuff turned on, it will take even longer but it should work, no tricks needed.

Thanks! Works on the 3113. It's shows charging and doesn't show as media device on the laptop. Nice find.

Hi.
I have a couple of these usb adaptors, see link below, I bought them years ago for the original 7" galaxy tab but i never used them.
If i plug my tab2 into an usb2 port i get the red cross on the battery icon, so i tried one of these adaptor and my tab2 is charging from an usb2.0 port on my notebook and according to battery monitor widget pro at 14% an hour, and i have a lightning bolt sign in the green battery icon.
I did a search for the adaptor i bought and i think i have found it for £6.50 each, see link below.

the tablet charges anyway so the icon says no
In 4.0.4 rom the charge icon its fixed, anyway charge by USB is too, too slow, only use for emergency

Rapid Chargers No Longer Charge!

One of the things I loved about the Nexus 6P was how fast the stock Huawei Type C charger would charge the phone. I would plug it into the phone, the phone would show "Charging Rapidly" and a lightning bolt on the battery icon and in no time at all it would be charged. But about a week ago it stopped working. And I don't mean just stopped "Charging Rapidly", I mean no charging at all - no lightning bolt on the battery icon. At first, I thought I saw an occasional flash of lightning on the battery - just for a moment - but not enough to charge the battery. The battery would continue to lose power while it was plugged in. So I tried different outlets thinking maybe something had gone wrong with that one, but no luck. I decided the stock Huawei charger or its Type C cord had gone bad, so I ordered what appeared to be a very similar one, the SONEic 5.0V-3A, 15 Watt charger, which had excellent ratings and reviews from Amazon. But it also failed - not merely in "Charging Rapidly", but in charging at all. Note that my non-rapid-charging charger that I use at night still works just fine. Does anyone know what is wrong here and/or how to fix it?

So you're saying that any [email protected] charger won't work? Are you using the same cord for both the Huawei and SONEEic adaptors? What is your non rapid charging charger exactly? Using a different cord? USB-C? USB A to C?

Thank you, eregev, for responding.
I have only tried the original stock Huawei charger and its type-C-to-type-C cord and the new SONEic charger and its type-C-to-type-C cord. (Note that I have corrected the spelling of "SONEic" in my original post.)
I used each rapid charger with its own cord.
My nightly non-rapid-charger is an enercell type-A to type-C. It says:
INPUT: 100-240V- 50-60Hz 0.3A OUTPUT: 5V===1A
The "===" actually shows a solid line on top. I'm not sure what that means or if it is important.
=== Additional Info ====
I almost forgot - I also have a portable RAVPOWER Turbo Series (RP-PB043) 20100 mAh battery charger that provides rapid charging with its own type-C-to-type-C cable. The type-C port output that I use is "5V 3A Max". I used it on some airplane flights about a month ago and it worked then. I tried it when the Huawei first failed and it also failed to charge at all. Normally when one plugs a charger into the phone, the phone's screen comes on and shows that it is charging. Nothing happens with the RAVPOWER now.
I also have a charger in my car that I occasionally use (mainly if I am using the phone for navigation). It also would show "Charging Rapidly" when I plugged it in. It is different in that it uses a 6-foot Type-A-to-Type-C cord. I had not tried it since the noticing the problem with the other rapid chargers. I will try it now and repost the results.

Crazy idea, but did you try rebooting the phone then plugging it in. Just give it a shot.

Lol, yeah I had the same thing happen to me. I saw that fix somewhere, and thought to myself, "It can't be that simple." Turns out it was. Glad it was able to help you out.

There is a power management chip in all phones.
I have seen this behavior on a previous LG G3, Galaxy S4 and even my own Nexus 6P.

Glad you got it sorted out! Btw, the parallel dotted and dashed lines indicates that it's DC power out vs the input being AC power (the same icon, but with a sine wave instead). #themoreyouknow

The funny thing is that third party chargers are unaffected

I have the same problem but mines permanent. Only chargers that work are usb-a to usb-c. I also no longer get any connection when plugged in to the PC.

The solid line over dotted is a diagram for direct current power; whereas ~ is the diagram for alternating current. Just some info for you.

I no longer have rapid charging tried reboot even installed a different rom new charger but still no rapid charge and sometimes it won't charge at all
Any ideas

Check and make sure you don't have any lint or debris in the USB port. I had to clean mine out with a needle and magnifying glass and then rapid charging worked again.

Fast Wireless Charging Works but regular Fast Charging does not.

Like mentioned in the title, my fast wireless charging works, and when I put my phone on the pad it tells me it is fast wireless charging. However, whenever I try to use the cable directly and not wireless charging, it becomes cable charging which is incredibly slow (8-10 hours for 50%).
I have obviously checked all the simple steps. I'm using the adaptive charger, I'm using a good cable, fast charging is turned on in settings. I even tried factory reseting my phone but still no luck.
Is it possible that my charging port is loose? And if so is there any way to fix this?
The other possibility I'm thinking of is that my Europe to America convertor might be bad (I have the international version so I have to use the plug convertor) I recently lost the one that came in the box so I had to buy a new one off amazon. Are there such good things as good and bad convertors or are they all the same. And if it is the convertor, why would the wireless charging work but the cable charging not.
EDIT: I just checked plugging in an S6 to the cable and it says fast charging. Does that mean it is definitely the port on my phone?

May sound odd but have you tried unplugging and replugging the charger in over and over to see if one of those times it pops up as fast charging?
i had this problem with my Note 5 (im in the UK and note 5 was not released here so i had to buy a Russian variant and they sent with 2pin to 3pin adapter)
I don't think i ever had a fix for this other than using a different fast charger without the adapter..
However like you The official note 5 charger with adapter does work to charge my s7e fine though
so our problems seem pretty similar... Maybe buy a new fast charger that doesn't require an adapter and try that?

How to tell if V20 is Quick Charging?

I have a Verizon LG V20 (LG-VS995LG-VS995). I would like to know when it is in Qualcomm Quick Charge (QC) (aka Adaptive Fast Charge) mode. There were a couple of ways to tell with my ol' Note4. With my new V20, either I'm never in QC mode, or I'm not looking in the right place. Does whatever the indicator is differentiate between 2.0 and 3.0 (from what I've read, the V20 is supposed to take 3.0)?
There are lots of apps related to battery use. Anybody's happy or unhappy experience with those would be of interest to me too. I started looking at them, hoping for a simple way to tell if my V20 is in QC mode, but, alas, I read through several apps' descriptions, and nobody was touting that.

Should appear in your notification if it is fast charging. Usually pops up within a second of plugging it in.

Says fast charging on the lock screen and also if you drag down the notification bar it says fast charging.

Apps aren't as quick as an inline usb meter. Used a yzx studio zy1270 and it says the stock charger does QC3
For a quick tell as the others have said it says fast charging on the lock screen with Qc3. If you don't see the word fast a few secnds after plugging in then it isn't fast charging
Bear in mind that quick charge only works with the screen off. If you use the phone with the screen on the power input drops from a max of 13W when battery is under 70% and charging to about 5W
The USB interface is usb c but the v20 is actually usb 2. So i use the charging cable that came with my G4, usb a to micro usb cable with a micro to usb c adapter and it quick charges just fine
