Warning message - charger

My HTC One showed an warning message about not using the right charger! I was using the charger from my Samsung Note II. I thought HTC encouraged customers to reuse existing chargers? Anyone else seen this message before? I'll use the HTC charger now in case I mess-up the battery.

Its because the note 2 uses a higher amp 2 i think to charge.
I think it was the carriers that wanted to reuse old ones. But its best to use the one that came with your phone.

It's pretty neat that they warned you when you used a different charger cause if something messes up the battery, your only option is to replace the phone.

I certainly wouldn't want to use a charger that's running at 100% above the systems designed input level. I've been in a room when a L-Ion went boom.

has anyone tried charging from the usb port on a pc yet?

As soon as you plug the phone into a PC it is charging.. Much lower output. Never gonna be an issue

I think its fine to use different chargers , as long as it doesnt overcapacitate ur battery. Note 2's 2amp charger might be bad for the battery because faster charge times wear the battery faster

The phone decides how much current to draw, not the charger.
Imagine the phones sucks the energy instead of the charger pushing it.
Interestingly I didn't see that warning yet besides charging my One with fourdifferent chargers (old HTC, original One, Nexus 7 and a Sony one...)

How about using galaxy S2 and S3 charger I got both, is it safe for HTC one ?

Can some expert publish list of safe or compatible charger models which we can safely use for HTC one?

As someone says, phone decide how much power to draw not chargher.
Chargher just transform 230V AC to XY V DC. 2A is just max power he can provide.
But phone will draw 1.5, 1.7 i don't know how much cuz i don't own it yet.
Only problem is if you have lower power chargher then phone want to charghe is that charhing will lest for hours.

Charger acts like sophisticated pressure regulator.
Its task it to take 100-240V~ convert it to steady 5V DC and provide current. How that current is used is responsibility of device internal circuitry.

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

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.

using a mytouch wall plug to charge htc one

will this impact my battery in any negative way besides maybe slower charging? if thats the case its fine as i charge my phone over night anyways but i just want to make sure its not harming my battery as i cant find my original wall plug
on the wallplug it says
input 100-240V~200mA 50-60Hz
output 5V____1A
If anyone could maybe compare these numbers to their original wallplug maybe that would make me feel a little better
thanks guys

The simple answer is no. The slower the charge the longer the battery will last infact. That's why HTC didn't allow fastcharge, because our batteries aren't removable.

USB Fast 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.

What's different about the M8 Charger?

I've been out of town and only bought a couple chargers with me. I'm finding some weirdness as I do some tests with these and some other device I borrowed while here.
Basically, the M8 Charger seems to only work to charge the M8. It doesn't work to charge a Galaxy S5 or an iPhone.
I have successfully used the following to charge all 3 phones:
- Computer USB (0.5 - 1.0 A)
- iPhone Charger (1A)
- iPad Charger (2.1A)
- RAV power brick (2.1A)
However the M8 charger will ONLY charge the M8.
It clearly isn't an amperage issue since the M8 charger is only 1.5A.
So what is it?
Since all the other adapters I tried seemingly work on the M8, but the M8 adapter only works on the M8, I'm wondering why I don't just throw the M8 charger into the "bin of forgotten things" ?

I've used my M8 charger for a Note II, an iPod and an iPad with no issues. Something's wonky with yours, imo.

I don't know, but something is off about mine. The stock ROM throws a fit about it not being the OEM charger and that it's in slow charge mode. It's the stock OEM charger I took out of the box one week ago. Lol. 1.5A and all.
It does still charge though, and it charged my HTC Droid Incredible, iPod 5G and Classic, along with my BlackBerry Z10. No issue there. Just the opposite.
I'll assume it's ok though, I just plug it in for the night. And I'm now on the GPe ROM so it doesn't pop up slow charging info, and I don't miss it.
I'm wondering if it just can't match the 1.5A it's supposed to have, maybe falling short? I'd try a 2A charger, but I haven't got any since I sold my iPad. And my Z10, Dinc, and iPhone/iPod chargers are all 1.0A. But since I only charge it at night, it doesn't make a difference anyway.
I'd love to know what's up with yours though. Something about HTC chargers seem to be odd. The one from my 2010 Incredible works, but makes a terrible whine so I can't even use it. It started maybe a year in and I switched to another brick that's been fine since.

Maybe you should try charge to BlackBerry playbook?
