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.

Hello all. I found some information that some of you may find useful, so I wanted to share.
If you are running a custom kernel, go download Current Widget from the market
https://market.android.com/details?id=com.manor.currentwidget&hl=en
Install it, add the widget to your screen, and plug in your phone. You should be getting 350-380mA, this is AC charging mode. If you are getting in the low 200's you have a charger or cable that is not bypassing the data+ and data- wires in your phone, this is called USB charging.
If it is showing 0mA, then your kernal is not supported and it will not work. You can still do the steps below and get the same results, you will just not be able to see the data visually. I am running Gummy2.0 and the widget works great.
Some chargers are built .. badly.. and rely on a specific cable that will bypass the D+ and D-. the problem is, that cable will not work for anything USB related, such as flashing roms.
If you are anything like me, you have a dozen USB cables laying around and just use the closet one you can find when you need to charge up. However, if you use a data cable with a wall charger that does not disable D+ and D- you will charge at the USB charging rate, which is much slower than when AC charging is enabled, and can be irritating when your phone drains more power than its getting from the charger, resulting in power loss. This happens often while using your phone as a wifi hotspot. In USB charging mode, you can potentially drain the battery faster than the charger can charge. This can be prevented by being in AC charging mode.
You can either dig around for cables and test them out with your charger to see if you can get up to the 380mA range, or you can solder the D+ and D- points together in your charger. I do not recommend the 2nd option unless you are failure with soldering on small IC circuit boards.
But if you are adventurous, the 2 center pins on the USB cable are D+ and D-. If you open up your charger you will see the backside of the USB port and notice the 4 solder points that connect to the USB plug side. Place a bead of solder between this 2 to short them together. This will allow the charger to be in "AC" mode and charge at the higher rate.
This will also work for USB plug car chargers and will allow your phone to continue to have a positive charge even while navigating (which as most people know, Navigating can still drain your battery even when its plugged in).
Hope this helps! Feel free to ask any questions, I will do my best to answer them.
-EDIT-
Make sure to set the update interval in Current Widget to 1, for 1 second updates, this will help when monitoring the charge current.
Let me test this out... I'll report back in a lil bit. Calibrating battery, can't charge. Later...
I'm using a 10' cable from Monoprice. I'm getting 373mA. I'll post on what I get using my car charger... but I'm getting pretty good battery life that I rarely have to charge it in the ride
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) ?
hi,
i have just bought the S4, the only problem is the white mains power charger cable is too short for me.
Can anyone recommend an extended mains power charger that is compatible with the S4 i9505?
Thanks
Any micro usb will be fine just keep in mind the longer the cable the slower it will charge the phone. I personally bought a power strip to add more distance ... but I also have a 10ft usb cable that charges my phone very slowly
Don't listen to anyone that says to get a usb extension cable.
to answer you'r question, you can't get a longer cable for the s4, at this time.
the usb cable and charger are "special" you have to use what came in the box to be charging the phone at ~1.5 amps, if you so much as just use a different microUSB cable, the current will go down to ~0.75 amps (effectively doubling the required charging time). same goes for the wall adapter.
i tried 3 different usb type-c cable including the one that came with the phone and it barely charges through pc or usb. i would plug it in at around 20% to my pc and 30-40mins later its at 20%.......... is this norm for everyone? its kind of frustrating when i do not have charger with me all the time
is it the cable problem? please help me out here
PC USB outlets do not give you enough current to charge today's smartphones. You need to use a wall charger with the right voltage and amp.

Ur pc will never charge it as fast as the charger does. However, your motherboard may have a software which speeds up charging. I have a gigabyte mobo and its soft named "on/off charger".
Its pretty much as the others have said. If the phone charges fine from a wall socket, Its most likely a PC problem.
Smart phones need a lot of power to charge them, usually 1+ amp
But, most PC USB ports (USB 2.0) will only give out 0.5 amp, so 'if' they charge it, it will be very slowly.
A PC with a USB 3.0 port should charge it fine, but not as quick as a wall charger, especially if it has a 'Quick Charge' feature.
