I have a question for the xda community hopefully you guys can help me out: ok so i have been charging my tab in my car using both the cigarete lighter and ac outlet, but i have noticed that it discharges faster than it charges, for example if i am using the gps while charging the tab the tabs battery will drain. On the other hand if i am charging the tab at home on a regular wall outlet it charges fine. In comparison my samsung galaxy s charges fine in the car via the cigarete lighter. I am using the original charger that came with the tab. Any ideas as to why it drains faster than it charges? Thanks.

The Galaxy Tab USB port is wired slightly differently to other USB ports, which results in only getting a trickle-charge from regular USB cables. You need something like this...
http://cgi.ebay.in/USB-car-wall-charger-adapter-plug-Samsung-Galaxy-TAB-/190522553195
I can't vouch for that particular seller, but I have one of those adaptors and it makes all the difference when plugging into anything USB.
Incidentally, when you say you're using the charger that came with the tablet, are you saying that it came with a car charger? I've not heard of that before.
Check the output of the charger. It should put out 2000mA. It should be written somewhere on the charger.

What I meant was that I am using both the cable and adapter that came with the tab on the car ac outlet

I had read that the port was wired differently. Thanks for the link into ebay for the charger adapter. For the price, it's worth checking out.
I guess I can give it a try

Does anyone know why the One might behave differently on a car USB charger compared to a Galaxy S3?
I noticed my One was charging slowly or not at all when in the car. Using the power stat screen in the SystemPanelLite free version it shows the One is only connected at USB charge power, not "AC" power. However if I plug this same cable into my old Galaxy S3 it shows in SystemPanelLite that it is charging at full AC speed. I tried both the One and S3 default charging cables, no difference.
I'm using a car charger rated to put out enough amps for full speed charging, and it works great with the S3. With my One I tested it just plugging it into the charger that came with it (AC outlet, not in the car) and only then do I get full AC charging speed.
Anyone have ideas on how to get full AC charging speed on the One in the car? Any suggested car chargers confirmed to charge at full speed?
quick charge is disabled. you also need to make sure the charger is at least 1A @ 5V.
On previous HTC phones, I'm led to believe that the data pins on the USB connection are shorted inside the charger, and that's how it detects AC vs USB. It's not AC arriving at the phone of course, in reality it's 5VDC, with "AC" it draws 1A vs 0.5A for USB.
If the USB cable is not wired appropriately, the HTC One will slow charge so that it doesn't draw more than the USB standard 500 mA. Your charger needs to be wired accordingly so that the HTC One knows that the charger is capable of supplying more current, otherwise the device won't pull the extra current to fast charge. See http://forum.xda-developers.com/showthread.php?t=844284 for details.
Benpope and rumball have correctly answered.

Will this charger work with the HTC One @ 1A? http://shopamerica.htc.com/product/productpop.htm?prId=41645
Well at this point I'm looking for anyone who can confirm they have a car charger/cable combo working with the One that will charge at or near 1 amp.
I don't think my cable is at fault since I've tried multiple ones, including the AC one that came with the One.
Although my current car charger worked great with my GS3, I guess the One is more picky. So can anyone recommend one that will definitely do 1 amp with the One?
the data function on the car kit cable doesnt work as well...plugged into computer and charges but nothing else (to bad to, liked the length of the cord)

This is right, I had same issues with s3, resolved by buying a genuine Samsung charger. Before my Google maps drained more than it could charge. What's odd is that the s3 charges fine on his cable, unless different pins are shorted on an htc?

Thanks, just making sure. Replacing chargers and car chargers and HDMI adaptors is almost as expensive as the phone itself. :laugh:

Careful. HTC does something funky with the wiring in their chargers and phones such that, when using a non HTC charger, the phone will only charge at 0.5 amp, vs 1 amp with an HTC charger. Net result is that your phone will take twice as long to charge with a non HTC charger. There are several threads on this subject, and I've observed it first hand on my One. The non HTC charger shouldn't hurt your phone though, only your patience...

I've never had an issue.. have had HTC for years now and have gone thru several chargers bought from walgreens and they all seem to work fine. I usually charge overnight anyway so I never time the charge lengths. Ymmv I guess?
Sent from my HTC One using xda premium
I usually charge overnight as well. But I travel a lot, and when I do the GPS - a battery burner - gets a lot of use. What got me started exploring this, was when I saw my HTC ONE battery going in the wrong direction (slowly) while charging in the car while using the GPS. This led me to learning more than I ever wanted to know about HTC chargers and their funky wiring ... Apparently you can get around this by shorting two wires in the USB cable, but I have no intention of trying that!

I don't think the problem is at HTC but the charger you might have. I have successfully charge @ ~800mA (1000mA = 1 Amp)with different chargers ( Asus charger, Samsung charger and a newer palm charger). My new blackberry charger can charge @ ~600mA.
If I use my older palm charger, my Nokia charger, my old blackberry or a dollar store charger, it will only charge @ ~3xxmA.
If you read the spec carefully, you will see most newer *smartphone* charger max @ 1A, and older charger max @ 500mA. (or my BB charger max @ 800mA. )
So it's OK to use non HTC charger, just be sure to read the spec and find one charger =>1A.
Hope this help.
I'm on the lookout for a car charger someone can confirm will charge the One at full 1A speeds. I don't mean one where it claims to on amazon's site, but that you've actually witnessed it. Thanks for any help!

That is correct, usb specification is 5v, with 500mA (0.5A) maximum, hence the modified cable you refer to. The simplest way if you don't wish to modify cables is to buy HTC car charger

Which will charge at up to 1A with any HTC phone

You can find HTC chargers on amazon that will give you the full 1 amp. Look for older phone models like treo pro or mytouch 4g and they'll be cheaper but work fine.

What happens if I charge the phone with a 2am charger? Does it damage my battery? Will it charge faster?

The charger *should* only provide 2A if the device (phone) request it.
Just thought I would chime in on some observations here. Long story short, when I bought my HTC One, I left the charger in the box and continued to use my multi-port USB charger with 3x1A ports and 1x2.1A port.
When connected to the 1A port, I found it quite strange that my phone was taking 4 hours or longer to fully charge. Also observed the same thing when connected to the 2.1A port. I was thinking that something was up with my phone somehow limiting the maximum charge current.
Anyway, I read a suggestion to use SystemPanel Lite to check for USB or AC power connected and sure enough it was reporting USB power. I remember the case with my Xperia X10 where you have to short out the two middle (data) pins on the cable or in the charger so that the phone detects that it is being connected to an actual charger. I tested it with my old Xperia charger, another generic USB charger, and the HTC charger and managed to get SystemPanel Lite to report it as AC connected.
But here is the interesting part. I have a car charger rated for 1A. Initially it never worked with the Xperia X10 until I opened it up and shorted out the two data pins. It has worked ever since. However, when I connect this to my HTC One, it still reports it as USB connected.
This has got me thinking that there maybe something more than just shorting out the two data pins for the HTC One to detect that an actual charger is connected. Just some food for thought.
Don't tell me HTC pulled an Apple and we have to buy only HTC chargers to get full speed charging? Does anyone have a confirmed non-HTC car charger that reports "AC" charging in SystemPanel Lite?

As per my post, I tested a generic USB 1A charger (it's at home, but it was one that was supplied with a Netcomm MyZone) and with my stock Sony Ericsson USB 700mA charger, both of which reported as AC connected. There has to be another way that these can be detected as chargers other than a simple short of the data pins.
Tested not to work so far has been an iPhone charger, Amacrox AX025-TACH1, Philips Power Bug, and two generic USB car chargers both with the data pins open then shorted.
Non HTC charger plugged into wall reports ac power. Proof

Good point. My apologies. The work "car" managed to be skipped as I read it.
Hi guys,
I'm having an issue with the charging cables and my note, so I'd like to hear if someone has an answer to this thing.
In short, I have the official Samsung charger and a Note that's fully operational, no dirty contacts on the charger, no broken pins or anything.
When I use the short Samsung USB cable with the charger, my phone charges normally. Yesterday I bought a longer USB cable(1.8meters long) and the phone just discharges during charge if I use it.
What's the huge difference between these two cables that makes the one I bought not work with my phone? Does anyone know of a certain brand of cables that 100% works with Note that I can order from eBay? I really need a long charging cable, and this Samsung one just doesn't cut it.
Thanks for the replies!

Try using a 2A charger..
Seeing as the M8 supports fast charging, but the charger in the box is the standard 5v/1amp charger, would anyone know if the new Google charger would work for fast charge?
https://play.google.com/store/devices/details/Nexus_Charging_Accessory?id=nexus_charging_accessory
It's 9w/1.8amp output. I have one and was thinking of getting an M8 so it's something I could keep to use if I do get one
(If this should be in Q&A please move it, but thought it might be handy for anyone looking for a fast charger from a reputable brand should it work)

My M8 was getting very warm using this charger, is yours?
Not that I have noticed but I'll keep an eye out when I get mine back. It does charge everything I own quick as hell though.
They're supposed to be releasing a quick charge 2.0 compatible charger for our device soon that's supposedly is pretty good. I find my phone charges much faster than my DNA as that thing had a slow charge mode that was brutal.
I have a few red band charge only cables that charge the phone fairly quickly.
The charger that came with my htc M8 says 1.5A on the back of it. It charges the phone pretty fast compared to others I have used. I did try to use my samsung charger that is 2.0A but I noticed the phone got warm. Definitely not hot to the touch but enough for me to not really want to ust again and stick to the stock charger.
The charger that came in my box was 1.5A.
Sent from my HTC One_M8 using xda app-developers app
The stock HTC charger is 1.5 amps, or at least the ones in the UK are.
While the phone can take 2 amp charge, by doing so you will heat the battery up much more on each charge, and this extra heat will reduce the charge cycles of the battery(life of the battery), not really the best thing to do on a phone that can't have it's battery replaced.
I've got a 2 amp charger for the car, as when I use that I tend to need power fast, but I have my phone mount on my aircon vent so the phone is kept very cool even if using google maps while fast charging at 2 amps.
How do you tell if a charger has Quick Charge or not?
Apparently the one that comes in the box with the HTC One M8 has Quick Charger 1.0 but I'm looking at the charger now and there is nothing on there to say that it has this feature
I would like to buy another one as a spare to put in a different location to charge without having to take my charger with it but I don't know how to tell if it has it or not before buying it without getting it and actually plugging it in and using it
M8 has quickcharge 2.0 but no 2.0 compliant chargers have been released, the stock charger uses quickcharge 1 technology, HTC is panning to release a qc 2.0 compiant charger later this year.

What do you mean by Samsung 3.0 :S
You're not talking about USB 3.0 are you?
Then yes the Samsung Galaxy S5 does have USB 3.0
USB 3.0 is just a faster way to transfer data and as far as I'm aware the charging speeds are still the same standard speed
You do need to have a USB 3.0 cable and a supporting device (USB 3.0 port) to utilise it the faster transfer speed
BUT in saying that the Galaxy S5 does have the same chip as the HTC One M8 as far as I'm aware so I would imagine it would have the Quick Charge 2.0 function as well but whether or not the phone has it enabled or comes with a Quick Charger I'm not sure
-EDIT
Just did some research
Turns out USB 3.0 standard port has a current of 900mA while USB 2.0 is 500mA so the power current on a USB 3.0 has also increased

Not the one with the s5 but any of their earlier cables would fit our M8's.
Hey guys, for the ones that asked I have got the Google nexus fast charger and it is not fantastic. Takes 1,5 hour to charge from 5 to 100%.
I was quite desapointed. This is incredible I can't find any quick charge 2.0 charger anywhere, did someone do ?
The compatible charger must have a qualcomm quick charge logo, they said.
