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.

Hey all,
I often charged my g1 through a USB cable from my computer (rather than from the wall). When I do this for the g2x, it doesn't seem to charge. It either retains it's charge, slowly discharges (more slowly than if it wasn't plugged in), or if I am using an intensive app (e.g. pocket legends) it will keep discharging quickly. Is this normal or is this just me/my phone?
I am using the cable that came with the phone that I also use to charge through the wall (so not a cable issue).
Thx
It charges fine through my computer but keep in mind it will be a slower charge on any device. Maybe it's more slow than it should be on yours.

Did you try using other USB ports on your computer?
I've tried multiple ports and multiple computers (not multiple cables cause I only have 1, but the cable does charge through the wall adapter). I've left it plugged in to the computer for the past 2 hours with minimal use (basically just checking battery monitor occasionally) and I am losing ~2% charge an hour (I'll post a screen-cap after a few more hours of "charging").
mine charges.. very slow.
You should never charge your phone from a computer usb cable. There isn't enough amps to charge your phone while it is on and running. If you play games or listen to music while connected and charging from your computer's usb cable you will still run down the battery. The charger that came with the LG G2x is 1Amp or 1000MA! My previous Samsung Galaxy was around 700MA. Best way to charge your phone is to turn it off while it is plugged to the AC adaptor and use a high amp output charger like the stock charger. If you use generic ones with lower amp output like 500Ma, it will take longer.

The chargers for the gs and g2x both have the same amps. And Hz.
Where did you find that info?
Sometimes I still use my gs charger on myg2x. Both charge in the same amount of time.
But if it is true ill stop that right now.

I have just bought up my transformer ( Love it ) but it's at about 10% battery right now... I take the cable that came with it (the usb one) and plugged it into my computer but it is not charging ? Any idea what's wrong with it ? when i plug it into the charging unit it works fine though
i've heard it has to be turned off for the USB charging to work....
Like off as in screen off or off as in complete off ?
It will not charge in your computer. You have to charge it in the wall.

One of the pamphlets that came with it said the screen has to be off in order to charge it using a computer's USB port, cause the screen uses too much power and a USB port doesn't output as much, its best just to charge with the ac adapter. Nothing is wrong with your unit, thats just how it works.

Turn off the screen and it will charge. (you don't need to turn it off; you just need a black screen) It is very, very slow though.
My wall charger never charged my tablet so I am awaiting a replacement. The USB charge is MUCH slower than the wall charge. We are talking about maybe 4-5% an hour -- max with the USB cable alone.
Connecting this thing to a computer will NOT charge it. Even a normal 5V 1.2A-2A charger won't charge it fast enough. I used a 2A charger and it trickle-charged for over half a day and managed to clock in @ 50pc. I think the unit uses hardware info from the ASUS charger to detect the charger. Any other charger wont do.
Isn't the cable and charger USB 3 and charging is at non USB 2 values (voltage and current).
Good amount of mis-info in this thread...
The unit *will* charge from computer USB, assuming the USB port provides enough amperage (not voltage). I have not yet measured out the amps used, but it's on my list of things to do...
In order to charge from computer USB, the display on the Transformer needs to be off. The unit can be on, but it must be asleep.
The adapter that comes with the transformer provides 15VDC via extra pins which loosely resemble USB 3.0. These are *not* USB 3.0 data/power specs, however a USB 3.0 extension cord could be used to lengthen the existing adapter.
Any USB car adapter should work to charge this in sleep mode, similar to a computer USB port. In order to "fast charge" in a car, however, you'd basically need to use an AC inverter with an ASUS Transformer adapter.

Tried a 2.1A 5V charger. Took about 8 hours to charge @ 50pc. The ASUS charger is rated at 1.2A.
is the only way to plug the device into your PC or laptop via USB on the dock?
you cant use the proprietary charger cable to do USB data transfer with the charging cable USB component?
ie....to do data transfers via USB (not the memory card), the only way is via the dock?

No, one end of the charging cable is regular USB and the other end (tablet-end) is proprietary. You can transfer files over by connecting to your computer's USB.
awesome, thanks.
do you think that if you get a male/female USB converter, you could plug in a USB memory stick device or a mini hard drive device and have it work fine in the charging cable just like you would if you were to plug in a mini hard drive into one of the usb ports on the dock?
Anyone else having this issue? Went from completely dead 0% to now 17% in 2 hours! Maybe it's a bad battery? Used to charge from 0% to full battery in about an hour or less

Yeah I have noticed that, it's iffy sometimes it charges normally on my pc then there times when it just crawls like today it was at 57 % for like 1 hour I rebooted it thinking something was wrong.
My phone was very hot tho maybe that had somthing to do with it idk

never use your micro usb cable connected to your computer to charge your phone. If your phone is ON and playing music or something else, that will still run down the battery even though it is connected to the computer. Your LG G2x charger that came with your phone is rated at 1 amp. The computer usb port is giving out a fraction of that. Even cheap chargers from China that are 350mA - 500mA will take forever to charge your phone. I use spare Blackberry chargers that are less than $5 and offer 700mA. They are great and cheap.

It's very similar to the TF101; it seems most Tegra devices use a charging cable more like USB 3.0 than 2.0, which pushes a lot more power and charges the device quickly but when plugged into a 2.0 port the charge slows to a crawl. USB 2.0 simply isn't designed to push the amount of power these newer devices require.
When I try this it will not charge my phone. I tried on several computers at home and work Pc's. It actually drains it.
I wonder why that happens???
Not a big deal.
No problem, I always have to take my charger everywhere I Goto be safe.
All computers using USB 2.0 or USB 2.0 add-on cards.

Yes, a fraction of 0.5. USB ports can provide up to 500mA.
I just charged mine at work using a USB cable plugged into my monitor. I noticed that trying to charge it off my laptop doesn't seem to get me anywhere. It might require using a powered hub or something similar to get enough juice.
I usually slowly lose charge when plugged into the usb at work. Granted the screen is almost always on and the phone being used.
I've noticed the charge rate for differs depending on the usb charger rating.
For example, on my laptop usb, it charges very very slowly. but when plugged into my desktop, it charges just very slowly. So they must have different current ratings.
When using my eee transformer usb plug ([email protected]), it charges the phone very fast, like under 2hrs. When using a usb charger meant for a blueant headset ([email protected]), it takes like 4hrs to charge. Think the stock charger is at [email protected]
I use Battery monitor app to monitor my batt usage/drain. Haven't really paid attention to the battery gain, but from looking at past history graph, think when plugged into the laptop, it supplied like 5-15ma of juice. When plugged into destop it looks like at 55-400ma. The transformer usb provides up to 1200ish ma, and the stock gives 800ish ma.
Now does using different rating chargers affect the battery discharge rate and health of the battery?
Just because a USB port on a PC says it'll output 500ma doesn't mean it will, it's all up to the software. If your PC or phone is cranky and doesn't communicate properly, your computer's USB port will default to 100ma, and you can't charge off that
Mine charges fine on USB unless I'm trying to use it, then it is pretty much break even.
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

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.

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) ?
