[Q] Car charging at half speed?

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.

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?

[Q] Charger

Can someone tell me if the Htc One charger is the same as the One S please.

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?

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

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.

any benefit using 2amp charger ?

Hi, im just wondering is there any benefit using a 2amp charger on the htc m8 , faster charging ? i know HTC are gonna release a faster charger which is 1.67amp , is it just the amp or it has some feature Quick Charge 2.0 built in you cant get with other chargers ?
the HTC One is rated to support Quick Charge 2.0 capable of accepting up to 60 watts of power – an increase of almost 100% compared to phones with Quick Charge 1.0. The 1.5amp charger bundled with the HTC One (M8), however, does not support Quick Charge 2.0. HTC is planning on releasing an optional 1.67amp charger accessory that will come with the technology later this year
Thanks

Yeah, it will charge a bit faster.

I've used the 2.0A charger that came with my Galaxy S4 and didn't really notice the phone heating up to unusual temps.

You can use a 10A charger if you have one (and it works with your power outlet), the phone should never draw more than the maximum it draws.

I originally used the charger I got with my M8, but then switched to a 2.5amp charger. According to GSam, my time to charge from around 80% to full is around 15 mins, but with the original charger, it was around 30 mins.
So from my experience, it does charge faster. From what I have read about QC2, the technology is in the processor in the phone. The charger can be any type, as long as it is able to deliver up to 60 watts.
See here - http://www.zdnet.com/qualcomms-quick-charge-2-0-offers-75-percent-faster-charging-7000026519/

The tech is actually in both the phone AND the wall charger:
From http://www.qualcomm.com/chipsets/quick-charge
"While Quick Charge 1.0 rests in the devices only, Quick Charge 2.0 resides in both the device, offered as a standalone IC solution or as part of the PMIC (power management integrated circuit) of Snapdragon™ 800 processors, and in the AC/DC wall charger."
The one you link is worded a little ambiguously:
"Qualcomm hopes to take things further by integrating Quick Charge 2.0 technology into standard micro-USB AC/DC wall chargers. These chargers will look and work like standard chargers, but will be able to deliver Quick Charge to compatible devices."
I tripped on it a couple times when reading it too, but it's implying that the tech does not currently reside in standard chargers, since they're still working on integrating it.

guess i will get the HTC fast charger when out and i bet we should get compatible quick charge 2.0 chargers too
Thanks

The amperage of the charger makes no difference, the device will only ever draw the power it requires to charge, no more. so a 5a charger would be no different to a 2a charger if the phone only draws 1.5a for example. find out what the device needs to charge and get as close as you can to that size for protection reasons

Yes, it will charge it faster. I used my 2amp charger and it did charge it faster. The phone may have some protection built in to protect the phones hardware. But the battery can handle much higher charge rates and the battery shouldn't start heating up till 20-30 amps. Yes, that's right.
I use Li-poly to race electric RC's and we charge them up to 50 amps. This charger will --->http://www.hobbyking.com/hobbyking/store/__46368__iCharger_308DUO_1300W_Dual_Channel_8s_Balance_Charger.html
Most people only charge at 5-10 amps, but to get peak performance, you will need to create a bit of heat and that doesn't happen till 20-30 amps.

Since I jumped from my old note 3tothe m8 I was able to keep the charger and it's a 2A one. Will I get the full 2.0 benefits with it or must I wait for the HTC one?

You will get whatever amp the M8 can take. i assume its 2A
I have a 2amp charger and i use it for my M8. i only see about a 30 min different from using a 1amp charger.

Its not just Amps, quickcharge 2.0 Also bumps up voltage. I tested multiple combinations with my htc one M8, here are my findings:
Quickcharge 2.0 18W Aukey (with regular micro usb cable): 9v/1.1A (~10w)
Quickcharge 2.0 18W Aukey (with data cut off cable): 5v/1.52A (~7.5w)
Wall 5v 2.4A charger: 5v/1.52A (~7.5w)
Stock 5v 1A charger: 5v/0.99A (~5w)
Car 5v 2A charger: 5v/1.3A (~6.5w)
some old 5v 700mA charger: 5v/0.7A (~3.5w)
MacBook Air USB port (2013) (with regular micro usb cable): 5v/500mA (~2.5w)
MacBook Air USB port (2013)(with data cut off cable): 5v/1A (~5w)
Ipad charger rated 5.2V/2.3A : 5v/1A (~5w) (no clue why its so sucky)
Also I noticed m8 once connected to charger (non Quickcharge 2.0) slowly increases charge current. if voltage drops below 4.92v it drops it back to these fixed values, whichever is immediate lower: 3oomA, 500mA, 700mA, 1A, 1.3A, 1.42A. 1.52A
these values are as per multimeters.
my car charger is tricky, it sometimes just falls to 1A instead of 1.3 as it border lines V to 4.92 while at 1.3Amps. (it is rated for 2.4A)

Dude... This thread you replied to is a YEAR old!
This has already been heavily discussed in newer threads.

[Q] Quick Charge vs. Ordinary Charging cable?

I understand the M8 supports Quick Charge 1.0 with the supplied Charger/Cable (1.5A)
Not sure if any of you have the same issue as I do, however the cable supplied in more recent batches of phones are shorter. The last HTC Phone I had which came with a longer cable is my original Evo 4G.
I do have a Black Berry cable I use which is nice and long. Do you guys think the cable itself can hinder charging capabilities of Quick Charge? Are the Quick Charge cables that come with the phone specifically manufactured to work with Quick Charge?

no, the quickcharge is solely reliant on the output of the wall brick itself. unless the cable is broken any cable should do

HTC device do not have a quick charge notification like a few others. You just have to make sure that the charger you got is Quick Charge 2.0 certified and you should be good to go. There are quite a few quick charge 2.0 charging accessories out there now. My favorite is the Aukey car charger which charges my phone about 5 times faster than the old car charger that I've owned for five years. Makes a huge difference, especially when you have only 15-20 minutes in the car.
