I made an video/audio out cable with power connections. I bridged the USB data connections (white & green) so the phone allows full AC charge current.
However, when I connect the charger while outputting audio/video, it does not charge. Tbattery app shows that it is recognizing the charger type as AC, and the LED "breather" light on the hardware buttons indicates it's charging.
When I do not use the A/V output cable, I get about +200mA charge current USB, and when I plug it in regular AC charger, I get about +700mA charge current.
But when using my custom cable, I am getting about 100mA charge current, but the phone discharges faster when its connected.
Can anyone help me with this? I would really appreciate the help!

I bought the SlingPlayer app as a way to listen to news at work while I do my work. What I have noticed is that plugging it into my USB port slows down the battery drain of the app, but the power draw caused by the app is more than the USB port can provide, so after enough time, I have to shut down SlingPlayer to let the battery recharge.
Are there any settings that I can do (under clock?) to reduce the power draw?
Would finding a two male USB to micro USB cable from somewhere(?) do the trick, or is that dangerous doubling the amperage?
I am hoping there is an option that does not involve a power adapter, because all the plugs are already taken.
Usually computer usb ports are only 500mA. The wall charger that came with the phone is 700mA and the phone itself it's 1000mA.
So the phone is using 1000mA while you're providing it only 1/2 of the power it needs.
I would recommend getting a usb wall charger that supplies 1000mA or if you can find the Y usb cable for your computer that would work too.
Reduce brightness by 50% see if that helps , screen is biggest power consumer on cell phones. Or just power it from wall charger not computer USB port.
Currently using BuoyAOSPsy v131 ROM
I have noticed that my battery still drains while I am plugged in and the phone indicates it is plugged in. Have not tested this while plugged into a wall jack, only in my car or via USB to computer.
When this occurs I am using GPS/Navigation software, active data connection (ofc), and playing music.
Does USB or car adapter not supply enough "juice" for this phone to run multiple applications/features? Is there anything I can do to remedy this, such as try a different car adapter? What specs do I need to look for to ensure appropriate power transfer?
Thanks!
**@ Moderators: Hopefully I placed this in the correct forum. Since it is not necessarily directly related to the ROM I thought it should be kept out of the ROM's thread.
Yes you can easily draw more power then its supplying when using computer or car charger. Most of the time its only charging 500 ma when charging that method. Wall charger's I believe are 1000 ma. Navagation is a HUGE draw on battery.

Thank you for the info. Guess I'll just have to find a higher quality car adapter.
Actually ive read when using a data cable ie stock or regular micro usb cable on a usb port on your pc or a regular charger the max it will get is 500ma. one of the oem wall chargers (block with usb port) is able to supply 1000ma and the phone is only able to sense this the data pin + and - are shorted together. this tells the phone its charging ac plugged vs usb. now check the output of your car charger and if its able to supply more than 500ma then you can either short pins 2-3 on your cable or on your charger and you will get maximum current draw. Research it you ill there was an article posted on xda somwhere.
I'm getting 1000ma from both my ccar charger and AC adapter. u don't want to pin short a cable and charge from usb. drawing that much power will damage the port, it wasn't designed for that (1.0,2.0). USB 3.0, on the other hand :-D
Hi all.
Could the charger of desire work normally(when check in about phone it must be show AC not USB) for the HTC desire HD and Inspire 4g.
Thanks
If it shows AC that means you are charging through a power outlet and when it's charging by USB you are charging it through a USB cable connected to a computer
Charging through AC is faster then USB

Why does USB from PC charges slower than the one from the socket?

PC has only 500mA current output, your wall charger has 1A output
greater current faster charging-but this does not mean that battery has not its max. charging current!
higher charging current can easily damage your battery and cell phone.
I charge my phone with Xperia charger, with Kindle charger, with Nokia charger and many more. So far I have no problem with my battery. As long as on the end of the cable you have “micro-b usb” and stable (troublefree) electric transformator to supply that cable you can charge your battery. The time to charge may be different but the result is the same.

+1 you only have to use a micro usb!
The charger should work with any phone other than iPhones

Correct!
As long as it is a usb micro charger, it all works....
only the time required to fully charged varies...
I am using a Nokia USB cable as a Charge. Works fine too.

As long as the two data cables are connected to eachother, the DHD will recognise it as a wall charger, and it will use 1 ampère. Instead of the 0.5 amps when connected to a PC (when the data cables aren't connected to eachother).
You can buy "charging only" cables. They always charge at maximum rate and do not transmit any data. Usually come with external battery packs etc.
Just to clarify some. (Talking about USB2.0 as 3.0 has a little higher power)
The USB on computers are powered by the motherboard (if not using extra PCI USB card).
Usually the motherboard gives about 500mAh to each USB host. If that host has 4 USB connectors all those connectors share the 500mAh.
And just be careful to not go above 500mAh as some (older) motherboards or even add in card's cannot handle the extra power and will fail to work(permanently).
So a charge-only cable will not make a difference in this situation, same goes for using multiple USB ports as that also brings extra problems with it, as power/voltage doesn't flow in just 1 direction (when using 2 poles). You could blow out USB voltage regulators when connecting different USB power leads together.
As for the phone side you can also use a 5000mAh power source, as the phone will 'take' what it needs. For DHD the max charging power is about 800mAh~900mAh if I'm not mistaken.
As long as its 5V and somewhat stable.
So if you want to charge the DHD (or any other USB chargeable phone, mostly all of them) as fast as possible use the original wall charger.
If you have to do it on the PC/Notebook unplug as much USB devices as possible, so most of the power can go to the phone.
Also make sure the screen of the phone is turned off as that's the biggest battery drain of the DHD. Thus also making charging slower (when on).
I'm using htc charger to charge my e-cigarette . It's works good.
If you plug it into USB socket, and enable "Fast charge" option, does it do anything? Does it block the data transfer and acts like a wall socket (1A) ?
Is any difference charging my DHD form PC's USB then charging from original charger ?
I may be wrong, but I think wall charger provides more power than USB or car dock

I've read many times that using USB, you battery might last longer than using the wall charger. I've never noticed this...
USB seems a bit slower than the wall charger but other than that seems the same.
Install Battery Monitor Widget, and you will see how much current each option gives at different levels of charge.
To be exact, the device DRAWS current, it's not a question of the highest output being the best. If the device can't receive more juice, the additional output cannot be used.
When the battery is nearly empty you will see the biggest current draw - as the charge gets closer to 100%, the amount the device draws drops, until it reaches 0mAh on full charge.
My OEM wall charger provides up to 1000mAh, and the PC USB provides 500mAh, you will initially charge the device faster with the wall charger, until the current drawn by the device drops beneath 500mAh - after which point they will charge equally fast.
That, in the case of my phone (with a Mugen 1500mAh battery) happens around the 60% charge mark. So if the charger outputs are as mentioned above, you wouldn't see any difference in the rate of charging after 60%
HTC wall charger can output 1A with data pin short-circuit. PC USB can output 500~600ma or 1A on some laptop but no data pin short-circuit.
Fast charge mode is 900mA. It is on when data-pin short-circuit is detected OR on a fast-charge enabled ROM (or say, kernel).
Otherwise, it only pull 500ma.
Use your battery in your way. Charge it when you like. DHD can replace battery.
Stating the obvious BUT, of course, you can access your phones storage when connected to PC via USB for charging!

Also, be careful of using unpowered USB hubs - there may not be sufficient power on the port to charge effectively.
I think charger will have more power. :cyclops:
A wallcharger will always push more amps to the phone.
Don't get confused by people telling you, that wallcharging will damage your battery! That's just not true.
Every phone has an inbuild unit, that controls the amps going to the battery.
Charger outputs more power and therefore it charges faster. Some kernels have the option called "fast charge" which allow you phone to drain more power from the PC and allow it to charge almost as fast as via charger. You can not access files while connected to the PC if the "fast charge" option is enabled.
As already stated above, AC charging is generally faster.
Now many people say that charging by USB will make your phone last longer, but from my personal experience is quite opposite, plus, usb charging is easily interrupted (PC hibernating, stand-by, restarting, etc...). if you are comfortable with both ways (neither PC nor wall outlet too far away), use wall AC.
interesting, i noticed charging via AC (wall) gives my dying battery that extra oomph and seems to make my phone last longer in the day
I think Charger is always best than PC charging.
Its fast.
AC charging is faster due to a higher voltage and ma charge rate
USB uses a much more lower voltage and ma charge rate, it is true that USB charging is SLOWER and a myth is that USB charging does make your battery last longer.
On sense 2.1 I noticed my battery last 4 days with low - medium ussage because I only charged with USB but now I charge with AC with medium ussage my battery lasts a day.
With kernel tuner you can add a 4x4 widget which can tell you the voltage and mah raise / drain

+1. I vote AC charging
Charging with Original charger is awesome
Charging from Orginal charger takes less time then chargin from a pc usb
Charging from charger is faster, but charging from USB is more stable, as far as I know...Because it has a balanced voltage all the time. Not sure though. Just heard from somewhere.
When im using my nexus 5 in a car, or when powered form anything other than the official charger it takes for ever to charge.
If left overnight this isn't a problem, however when in a car charging from the lighter socket my nexus looses charge when streaming audio and using the gps.
The only thing ive noticed is that it appears to have three charge modes:
Wireless - charges reasonably fast
AC charges fast, but only appears on the standard charger with the standard lead
and USB when it charges slowly, or even looses charge.
any way to enable to AC mode when its connected to another ( ie third party ) charger?
it would depend where you plug in. via wall charger will be ac, via any other place itll be usb. and when usb, it will charge much slower than with a wall outlet(ac). that is normal and how its supposed to work. and if you are using a 3rd party charger, make sure it has the same voltage that the default charger has, or it will charge slower.
third party charger, mains output 5v dc, 2.1 amp, nexus charges slowly says it's usb. in car adaptor 1.5amp, 5 volt slow charge.
all checked with multimeter for output values etc.

Maybe you are using a thin cable?
Yup, it'll be the cable
Sent from my Nexus 5 using Tapatalk
I agree that it's probably due to the cable.
One thing that I've noticed (especially with a couple of my LG devices that have fast charge and it's more noticeable) is that a thicker data sync cable works better than a standard charge only cable, which are usually thin.
You could also try a kernel that has USB fast charge.
