QC3 - HTC One A9

Hello,
I just received my A9.
I immediately checked for OTA and Nougat arrived.
If I'm not mistaken, the A9 is now compatible with Quick Charge 3.
But the provided charger is not QC3 compatible, so I guess I need to buy the HTC 10 charger, but what about the usb cable ? Will the provided usb cable work flawlessly with the new charger ? Any risk to damage the phone ?
I'm a bit confused, so thanks for the replies

Your USB cable should work fine, unless it has gone bad which happens from time to time. Once you get a QC 3.0 charger, it will show on the lockscreen "Fast Charging" after a couple of seconds.

Thanx for the reply, I was really not shure because I've read somewhere to always use the usb cable provided with the phone.
I'm not against third-party charger companies but I feel the HTC 10 charger is the best way to go.
My A9u is an interim phone, waiting for the HTC "11 / Ocean" to be announced to replace for good my excellent HTC 10 I recently sold though I keep an eye on the U Ultra and its huge screen

Short HTC Micro USB cable

Hi,
I'm looking for a short usb cable to charge my DHD...I searched the forums and found this link:
h t t p ://shop.brando.com/brando-workshop-usb-to-micro-usb-adapter_p04234c1181d039.html
Will this be compatible with the HTC Desire HD?
I could swear someone I've met before - who has a Desire - has got a short HTC marked usb cable - does anyone know anything about that?
Thanks
As long as it's a USB to Micro USB cable any will do fine no matter brand.

It should be. Any standard USB cable should do.
try something like this :
www.dicksmith.com.au/product/E6201/milkshake-retractable-cable-usb-to-mini-micro
you can find these cables on ebay.
works well and also does mini usb. be careful some usb to micro usb cables are for charging only and do not have the data lines connected.
Yeah. I've always been amazed by vendor branded usb cables - nokia is guilty too, they try to give the impression that their ones are different but any compliant usb cable will work.
I've just ordered a couple of Micro to Mini USB adapters. I have loads of Mini USB leads at home but only 1 micro USB which is the one that came with the phone.
be careful with those mini to micro usb adapters as a lot of them do not have the data lines connected so they are only useful for charging.
I have a short Nokia CA-101D cable that came with a 5800. Works fine with Samsung i8910, HTC Desire and Desire HD (from my experience) for both data and power.
Cable is 20cm long and can be bought for less than £2 from various places including Amazon and Ebay.
Hope this helps. John

That's cute and clever that thing, but to the OP: if you want a short cable to charge off your laptop then it won't work. Even off the PC. It will only charge from the mains.

Errrm, no. Mine charges just fine from the USB port on the pc and laptop.
Yeah, can draw up to 500mA from a standard usb port.
lol damn i got a crappy usb connection then! I say there watching 60% for over an hour so I was left thinking it didn't charge, only transferred data!
IMO USB charges should be avoided, it should be possible to turn off charging.
While it is not exactly harmful to the battery like it used to be, I have the pretty strong feeling that low-ampere charges suck. Try it your self one day, after your battery is fully conditioned. Go down to like 40% of charge and then leave it at some USB port overnight. Then watch how quickly the power drains the next day. Then compare that to a charge from 40% to full on a high ampere (1000-1200mah) connections like the mains charger or a good car charger.
The charge seems to last longer. I have noticed this with multiple USB-charging devices now and I think it has to do with the amperage / time of the charger. The lower it is, the longer the charge takes the shallower the carged battery is.
That was the feeling I had too psychotic, but when I claimed this at a different forum I was laughed at and told that a full charge is a full charge except that a USB-charge takes longer... Do you have anything to back it up?
If looking to charge in the car...
... then aren't there specific USB cables where a couple of the pins are shorted or something so that the car panel opens? Seen a thread on this site, but can't find it right now!

Actually I read somewhere that a computer slow charge actually gives you slightly more capacity. Can't remember where though! makes sense since fast charges usually get a bit lower capacity.

I think that's the case. Slow charging via USB also doesn't heat the battery up so much, so is kinder to it.

Charging Speeds

Hi,
Wanted your thoughts and opinions on charging speeds. I've never actually timed how long it takes to charge. i leave it overnight and it's ready when i wake up.
When i plug the phone into the charger, it flashes up slow charging for 2 seconds then disappears. which got me wondering how much it's actually using.
i used to use Current Widget app on my Samsung S3 which told me exactly how much current the phone was taking from the charger. typically it was 1A via AC/mains and 499mA from a PC. Plugged in to AC, I could play a power hungry game and it would still charge the phone at a good rate.
The LG kernel doesn't like these apps - the mA value is all over the place but it's typically <500mA displayed.
I could buy a USB ammeter to work out how much the USB charger is supplying but do you have any other methods of finding out? Do you know what your phone uses?
at home, i use a Xtrememac dual USB charger, 2x 2.1A output with a shielded 3M USB cable. for those wondering, it's the same regardless what cable i use. Have also tried with generic usb chargers, iPad chargers and official and OEM cables from LG and various other manufacturers. Have also used a data-shorted USB cable from PC which is the same result.
I haven't tried the LG charger yet (mainly as it's a 2 flat-pin plug and i don't know where i put the box) but i think i recall it being a 1.8A charger.
I use an application called "charger report" which can display current consumption and Xtar "USB detector" device. They both show the same numbers. But Xtar USB detector can detect voltage of a charger. The charging current of LG g pro 2 is 1.4-1.5A when the smartphone is not used and higher when I use it. Using USB detector I found out that this smartphone can charge with maximum current a charger can give only if the charger's voltage is 5.3v. So it chargers at full speed with original charger and two other chargers I have: a charger from my Lenovo s6000 (2A 5.4V) and from my Asus t100 (2A 5.3V).
i tried that app too and got the same results as with Current Widget.
i'll buy a "usb detector". thanks.
I forgot to mention that it take approximately two hours for charging indicator to reach 100% when the smartphone reports that it fully charged. And it's necessary to left it connected to a charger for ten to twenty minutes to be really fully charged. Otherwise charging indicator will soon drop to 90%. One can tell if a smartphone is still charging by touching a charger or by looking at current consumption: a charger would be warm and current would be higher than 200mA.
Is the GP2 Quick Charge (1 or 2) enabled? I can't read anything about it other than it's in Snapdragon chipsets. Not sure if it can be disabled or not.

The Snapdragon 800,801 and 805 is for Quick Charge 2.0
The Snapdragon 600 for 1.0
ok, does anyone use a Quick Charger with their GP2? is it noticeably faster?

Hey ray-lee!
I just bought this phone and as it seems it could get someday similar problems as my former phone the Galaxy Note 2.
That phone has had problems with charger and cable also. I had to buy another set of charger and cable since the original ones gave up a few months after i purchased the phone (it was used). The cable managed only 500mA wich is very slow for a battery that strong. One night was once not enough to charge my phone from 30% to 100%. As it seems it is problematic to manufacture cables, that can hold up and continually grant the 1,8 A that would charge our device in just 2 hours. I read somewhere that the G Pro 2 is one of 5 devices that has blazing fast speeds on charging the battery. If you handle the cables with caution hopefully you will not encounter problems. If so my guess is, that you will have a hard time in finding a cable that can hold up. Sadly the stock cables are always more expensive. I do not get it, why companies dont build travel adapters that only charge ur phones built solid with sturdy cables to ensure the transmission of high currents. That way with charger + usb cable is just stupid, even when tis is an all in one solution.
I like this phone very much and i hope, that the cables will not be that sloppy as the cables that Samsung had/ still has. With Current Widget i get readings around 1500 mA (1,5 A) when connected to the stock charger. And yes the LG Charger is an 1,8 A one. I have also flat pins, but received an adapter to be able to connect it in Hugary.
Just sharing thoughts here, that will maybe helpful to someone...

i "think" as long as device has snapdragon it is Quick Charge enabled
I use the "Charging Report" app on my phone, and it reports proper values.
(Around 1500mAh with the LG charger, and around 1600mAh with the 2.0A Samsung charger.)
If your phone is charging slowly, check the CABLE. Cable can broke too.
(Many people complain about their Samsung charging cables, because they just stop delivering power after a while and just charge the device slowly.)

Official 22.5W Dual Port USB Type-C Charger has only 1 port with rapid charging

I just received the official Universal 22.5W Dual Port USB Type-C Charger from the Google Store only to discover that only one of the ports offers rapid charging (as noted at the bottom of the Nexus 6P lock screen). I tested this using the USB Type-C cable provided with this charger. No other device was being charged in the second port during my testing.
Major bummer since this is not a cheap charger. Anyone else run into this?
it says on the box that it "Intelligently diverts 15W to the port that need the most power" I'm guessing this isn't true?

Spoke with Google support and they said the exact same words. They confirmed that when two rapid-charging-capable devices are plugged in, only 1 of the devices will receive rapid charging. I don't have two rapid-charging-capable devices to confirm their claim unfortunately. The weird part is that it seems like only 1 port is dedicated to rapid-charging, while the other port will only provide "regular" charging. Going to return it.
It's quite straight forward from the rating itself. If both the port were able to radip-charge, the power should be 30W instead of 22.5W.
Ill have 2 phones to test mine with Monday. I'll post a video/picture for you guys.

Yes, but it makes it sound as if either port can deliver the full 15a if needed or if only one device is plugged in. If this isn't the case that is misleading and disappointing.
This is the second time I have seen someone post that the chargers Google is selling do not rapid charge. I have both the dual port 22.5w and 15w and both charge rapidly for me. Granted I only have my 6P plugged into the dual port. I was really worried after someone on G+ claimed the only way they were able to get the dual port to charge rapidly was with the type c to c cable that came in the 6P box.

Or rapidly charged my 5X with both cables ( the 5x one and 6'one that came with the charger)
My 22.5 W charger from the Google Store does the exact same thing. The port closer to the end of the charger gives "rapidly charging" and the other port just gives "charging" on my 6p with the other port free. Guess it isn't so automatic after all.
My wife's 5x shows charging from either port though. It seems the 5x has a lower threshold for displaying "charging rapidly" as it also shows this when charging from a 1.8 A charger that I have.

You should read people's post most thoroughly. He did NOT say that his 22.5w wouldn't rapid charge, he said it would only rapid charge from 1 of the ports.

This is because there is no RAPID CHARGING technology in either the phone or the charger! While either port can support 3A, they can't both do 3A simultaneously! Hence it is 22.5W rated and not 30W rated.
Hmm, interesting. I haven't noticed this yet. When I do plug my phone in (top port), I'm pretty sure it said "Charging Rapidly," but I'm going to confirm this when I get home today. Part of me thought it was taking longer to charge my phone through this charger than the charger that came with the phone, but figured it was just my perception.

You're not understanding. Let's say the charger has two ports: A and B. They are saying that if they plug the phone into port A with nothing in port B, they get rapid charging. If they plug it into port B with nothing in port A, they do NOT get rapid charging.

I do get that some people are SAYING they are getting the Rapid Charging banner from one port or the other, but not both. Got it. That is a test of what the phone is doing and not what the charger is capable of outputting. At 75% charged, I plugged my phone into a 2A charger and it read -384mA current flow. A minute or so later it said +1256mA. This is showing both the lag in the updates to the app and that the power control chip is managing the power flow.
Put a known resistive load on the charger and measure the current with a multi-meter. It should be the same for both ports, assuming the other port is empty.
I am waiting on delivery of some non-Google 5V/3A chargers (car and wall), when I finally get to test them, I will report back.

I can confirm this as well on mine. With the same phone plugged into Port A it rapid charges, but when moved from Port A to Port B it does not.
At least we are finding out it's not either port... It's obvious that 22.5W isn't enough to fast charge two low battery nexus 5x or 6p at the same time... google even said that. It just sounds like you can't use either port for the fastest charging. GTK though. Since there aren't any other type C chargers available right now I don't regret buying the 22.5W dual port... just a little upset it's really only on one of the two you can get the real type C rapidly charging.

Well the fast charging is 15W so what did you expect when you saw the rating of 22.5W? One port is for slow charging no matter what and the other fast charges. The inside port is the slow charging on based on testing mine and the outside one fast charges.
ofc... but...

Mine too... I think many of us would have thought that either port should be capable of 15W fast charging our new nexus's... I'm not sure if this was some oversight or what because nothing on the website or on the charger seems to indicate one charge port is different than the other... that was my main point.

About quick charge

HELLO GUYS
i just got the tronsmart quick charger and remax type c cable
i see that its charge my xiaomi mi4c a little bit faster then the original one but theres not big diffrence
i tried on my girlfriend lg g4 and the charging is really fast
i think that xiaomi has built in limit for the charging
any idea what to do to skip that limit?
Until xiaomi releases kernel source code and a custom kernel is developed, nothing can be done about the charging limits (which is true and tested). I used the same charger to charge my HTC M8 and it has quick charge compared to the M8 original charger.

From what I have understood, the original cable that came with the MI4c is a modified Micro-USB type B cable, and not a "real" USB-C cable. So your (and my) MI4c phone draws a maximum of 5V~2A from the original charger and the standard USB-C cable, whereas the LG G4 draws a maximum of 20V~5A from the USB-C cable. This means that the LG get more power, faster from the USB-C cable you bought, and therefore gets charged faster - and you will not notice a big difference when using the USB-C cable, as your phone only draws the mentioned 5V~2A.
Do yourself a big favor, and throw away your original cable from Xiaomi, as it might potentially break your charger, laptop etc. if you use it in your girlfriends phone!

Good to know... I just assumed there was USB-C type cable to the G4 as OP apparently were able to charge the phone with a USB-C type cable.

Hi, I tried an Anker and Aukey quickcharge wall charger with some issues...I used till now the original battery charger with its usb cable. I usually charge the phone turning it off... When it gets to 100% I unplug the phone and then turn on .. that's normal ok... But I noticed that using another compatible charger that uses Qualcoom 2.0 quick charge technology.. once the phone gets 100% and I unplugg the charger my phone boots by itself.. Why does it happen with this charger and not with the original one???

QuickCharge 3.0, across 6 chargers, is somehow not working on my V20

I picked up a T-Mobile V20 2 days ago. Rooted it the same night, and tested out a few chargers I had laying around to make sure the ones I had, along with cables, worked properly after having most everything not work properly with my Pixel XL.
The stock charger would not charge my phone at more than 3 watts (but I never touched the stock charger until I started noticing the issue).
A Samsung QC charger, with any cable, would not charge my phone more than 9 watts.
An Anker PowerPort+ 1, Type C, QC 3.0 charger, with any cable (to include Anker cables and the Pixel XL OEM cable), will not charge over 12 watts.
Absolutely NONE of my QC 3.0 car chargers register as "fast charging" - these include an iVoler Type C and USB A, Anker USB A, Tronsmart Type C, with various cables. A standard cabled Type C charger from i-Orange does not say "fast charging," but seems to be charging at 5V/3A as it is MUCH faster than all the others.
The ONLY charger that is fast charging my phone is the Pixel XL OEM charger. Measured at the wall, it has peaked at 19.2 watts.
I'm really confused. I don't know if my QC 3.0 has been defective since I got the phone, or if plugging my phone into the USB PD Pixel XL charger somehow screwed things up...
Does anyone have any ideas here?
All my old QC chargers work and I'm currently using the note 7 oem one atm as it does not get as hot (charger not phone) as the LG oem one under load. What does the app ampere say your getting?
It takes a while, try a very low battery and give it 10 minutes or more screen off, must be cool too
I got an existing aukey qc 2.0 fast charging fine while using a Samsung adaptive fast charger also fine, I am waiting for my qc 3.0 aukey one to be arrived possibly tomorrow to see if I could charge faster and lower temperature than my existing ones, I cannot check the watts though
My phone is either defective (not surprising given LG's GARBAGE quality control) or the software has somehow screwed up from root, etc. (highly unlikely as I am the only one with an issue).
With that said, I made an interesting discovery. My phone, using USB Power Delivery, charges much faster than my girlfriend's, using QuickCharge 2.0 or 3.0. I tested this 2 times from 5% battery on both phones. I tested this with a QC 3.0 car charger and the OEM QC 2.0 charger. The difference is substantial... first test was about 40 minutes. My phone was near 80%, hers was at 55%. The 2nd test was only 15 minutes. Mine was near 40%, hers only 27%.

All my old QC chargers work and I'm currently using the note 7 oem one atm as it does not get as hot (charger not phone) as the LG oem one under load. What does the app ampere say your getting?

Don't remember what Ampere says, but it was <500mA. Also, I used a USB current meter. It hovered around 5V/0.5A no matter what charger I used. I don't have a Type C/Power Delivery current meter, so I couldn't test those chargers... but USB PD is CLEARLY working very well on the V20. Much better than QC.

It takes a while, try a very low battery and give it 10 minutes or more screen off, must be cool too

It does not take awhile - takes <5 seconds to begin the QuickCharge process. Phone does not need a very low battery - will show fast charging regardless of the %. Does not need to be cool - fast charging is shown when the QC handshake occurs - not based on actual charging current. My girlfriend also has a V20. Every charger I tested with mine (which did not work), successfully QuickCharges hers.
Are you you using 56 k resistor cables?plus being rooted a kernel app would have a section to disable fast charge or enable it. Most devs disables by default. So if using custom kernel something to look in to. As I doubt there is anything wrong with your phone.

Just got the aukey PA-T15 qc 3.0 seems fast charging fine though I have no time for a 0% to 100% test yet

All of my cables are good. No custom kernel, and I've never seen a dev disable fast charging by default... that would be very unpopular.
Anyway, it seems that LG's recent phones, to include the G5 and V20, are actually supporting both QC 3.0 and USB PD. This is also probably why QC 3.0 chargers that use Type C do not work (the Anker PowerPort+ 1 in my case). On a C to C connection, with USB PD present, USB PD will take precedence over QC 3.0 (since QC 3.0 is illegal with C to C anyway). But that still doesn't explain why my phone doesn't QC via USB A to C... so I'll chalk it up to LG's garbage quality control.
I'm glad it worked out this way. USB PD charges my phone WAY faster than QC 3.0 charges my girlfriend's V20. So I would suggest you all dump QC 3.0 (because it's non-compliant to anyway) and grab USB PD equipment since it's the way of the future anyway.
I'm starting to think that there's something wrong with the way V20 handles QC 3.0. I'm in a somewhat similar situation with you, tested three different QC 3.0 using almost 10 different A->C cable (including the OEM cable) and none of them would deliver QC 3.0 speed. (I just came in a from Axon 7 and the difference between charging speed is night and day).
Additionally, I wish there's an app to properly identify what's going on during charging.
Using the built-in battery test from Service mode (see screenshot), it always says that I'm on QC 2.0 whenever I'm charging using QC 3.0 chargers.
My unit (LG-H990DS) is charging very quick though.
Using stock charger & cable, charging time is very consistent from 0 to 100%. 95 mins is all it takes.

The stock charger that LG sent with the V20 is actually a QC2.0 unit.
and with QC3.0, it'll take you less than an hour to fully charge.

Original Charger
Aukey QC3.0 Charger
Both results are similar.
So now LG V20 under utilise the Aukey QC3.0?

I can't say for sure, because I have no way to get a baseline on how fast a QC 3.0 charger charge at the correct QC3.0 rate on the V20....
At least according to the battery test from the service mode menu, none of my QC3.0 chargers are being recognized as QC3....and it definitely doesn't charge as fast as 3.0 based on my previous experience with axon 7.
on The Axon 7, I can still be playing Mobius FF (which is very battery intensive) and still charging up at about 1% per minute.
I'm pretty sure our phone doesn't have QC3 as I just mentioned in another thread. I'm like.. 97% sure? I remember reading early on that it was QC2, and a blend of LG that got it a little more robust than that. I'm not sure all of what's required for QC3 to work, obviously the 820 SOC supports it, but, not sure why I read that we don't have QC3.,

Yeah, I'm starting to believe that's the case now. I just updated the thread btway, now they're saying that 3.0 isn't enabled by LG.
Not sure this is the case of Tmo employee not knowing their sh*t or what.

FWIW, I have a couple of Aukey chargers. One is QC2, and one is QC3. They both "fast-charge" my phone, but I don't think I get the fastest charge on anything but the LG adapter. Usually it's fast enough for me, but I guess if I was 10-15% left, and I needed 100% in less than an hour, it might not happen.
I just picked up a US996 (Unlocked V20)... and found this site while trying to make a decision on buying new chargers, cables, etc.
I opened a chat with LG to ask them if the V20 supports USB-PD... and I got this response:
Merwin
Not that we can verify, Ryan we because we have not tested it. I highly suggest you to use the OEM charger of the V20.

So... no help from Merwin @ LG. It seems they're not allowed to comment on it, and can only recommend the OEM charger. I was unaware that it was only QC2.0, according to the testing above.
Has anyone done more testing since? Can I buy a USB-PD charger and C-to-C cable? Should I avoid QC3.0?
Thanks
I'm interested in this as well having bought 2 QC3 chargers and neither charge my phone as fast as QC3 advertises.
I have used my brothers stock Nexus 6p charger from Google and the times are about equal to my QC3 chargers I bought
I'm using a Samsung QC 2.0 charger for mine:
https://www.amazon.com/Samsung-EP-TA20JWE-Travel-Charger-Devices/dp/B00TEUVEIO
I use it because I lost the LG one. It does quick charge but I can't measure the rate in the service menu. It just stays blank.
This is real easy, it happens with qc 3 on my v20 and s8+
The phone does not quick charge when the battery is warm or when the screen is on. Its really that simple. You can get faster charge times using a qc 2.0 charger or a dumb 18 watt adapter. Neither one is as picky about sending power to a warm battery, but your batteries life will be shorter than it was designed to be.
QC 3 will charge a cold empty battery faster, but in real life, it will preserve your battery over fast charging the phone.
