Hi all,
the nexus using a charger with a 5V output at 0.7A, the charger can use the HTC Touch Diamond which has a 5V output at 1A?
There is a risk of damaging anything?
I do not like to use an adapter for the original charger
I'm currently using the Nexus 1 charger (5V/1A) and the one that came with the Samsung Tab (5V/2A) - the Tab charger is handy since I can use it to charge anything with a USB data cable (e.g. Tab, Sony Walkman, N1, Blackberry, Canon camera and now NS).
I've not seen any ill effects, and according to a quick google it should be fine:
Increasing the charge current does not shorten the charge time by much. Although the voltage peak is reached quicker with higher charge current, the topping charge will take longer.

Hi guys!
I recently switched from a Samsung galaxy s5 to a nexus 6. It's been more than great, really. Why did I ever buy galaxy phones?!
I'm confused over quick charge 2.0 and compatibility with other chargers and couldn't find any proper information on the subject.
At the moment I own:
- Aukey 5-port 35W Charger
- Tecknet 6-port 50W Charger
- Anker Astro E5 15000mAh battery bank with 2A + 1A ports
- Large assortment of other single port chargers @ 2-2.4A from Samsung, ASUS, and several aftermarket brands.
All of these chargers, and the battery, delivered (tested with the Ampere app and tons of different cables) ~2A to the galaxy but only deliver ~1A to the nexus 6. The Motorola turbo charger obviously works as intended. Now my questions:
- Does quick charge 2.0 limit any non compatible chargers to 1 amp?
- Is there a way to mod chargers to at least get back 2A charging?
- Worst case, does anyone have experience with a recommendable battery bank and multi port chargers that support quick charge 2.0?
Thanks!

I'm using the franco kernel at the moment and as far as I can tell it doesn't have any options related to charge speeds. I'll look into other kernels.
Thanks for the info!

Why would you need options relating to change charge speeds? Qualcomm quick charger works on any kernel, if you're talking about USB fast charging, it's already enabled in Franco kernel.
There isn't a need to switch to other kernels.

@zephiK You misunderstood my question. The problem I'm looking to solve is the slow charge rate from the chargers in the original post.
To add to that. My macbook also charged my old galaxy phone @ 2amps but with my n6 only does 500mA.
Nothing wrong with the turbo charger

Laptop USB ports at limited to 500mah output unless its a dedicated charging port with USB 3.0 then It can push 1.6A so I don't see how that's possible to charge at 2A from a laptop.
@Pilz this is irrelevant. My 2014 macbook pro charges my old phone much faster than the nexus 6.
Refer to the original post for the topic at hand
Quickcharge 2.0 devices uses the data pin on usb to determine if the charger connected is a quickcharge 2.0 charger. The devices you are using do not have this capability so they charge slower. I do not think this can be changed kernel or phone side.
Thanks! I guess I'll have to replace the chargers/battery

I could be wrong S5 I looked up uses usb3.0 right? Does your macbook have usb3.0? If so then the usb 3.0 port can supply more current when detected being a usb3.0 device by your computer and ever more so it is possible for the mac to output a little more current. Can you plug in the S5 then open system profiler to look at USB device tree to see current being delivered? The nexus 6 only using usb2.0 would not get the same treatment by the comp and only receive the max standard of .5 A.
There are many details about the actual max current that can be supplied by the computer's ubs port that I don't know when they are applicable I've just stated reading so I'm not sure why you can get 2.0 A on your S5 and not less, since there are standards that set the max current. Even more complicated is that under certain conditions macs have their own heirarchy of supplying more current to some devices if they "say they need" more current and even then there are limitations. So again I'm not sure what is at play exactly, that determines why the S5 gets more than usual. The .5A is normal for current output on USB 2.0 in the nexus6.
I actually got this in the mail yesterday, and the wall chargers works great...Havent have a chance to test out the car one though!

That doesn't make sense which is why I went into some detail about laptop or any computers USB ports. I unfortunately had a MB Pro and hated it, and it never charged any of my phone a at 2A including my wife's old S5. I don't have it anymore so I can't test it again to verify. The person I quoted below explained it a little better than I did.

Qualcomm doesn't post every certified charger on their website. In would email the manufacturer and ask for their certification or a picture of it which most will show you assuming on they're legit.

It is technically incorrect for the phone to accept more than 1 amp on a 5v charger. The quick charge *protocol* negotiates a non-standard charge voltage (up to 12 volts!!!). Quick charge is actually BAD FOR YOUR BATTERY! The higher the current, the greater the temperature. The greater the temperature, the lower the battery life.
Unless you *need* it to charge that fast in an emergency, don't.
I've never even plugged in the charger that came with mine, and I don't intend to.

I've used QC 2.0 since I bought my phone during long days and my battery life is just fine. My battery is cooler during QC than when using qi charging so I disagree. Generally speaking you're correct, however the battery would need to get hot and stay hot which is doesn't. QC 2.0 tapers off the voltage and current overtime to a more "normal" amount. Your argument is an old and doesn't always pertain unless your phone is constantly hot.
You're battery degrades overtime anyway and any heat could speed that up. I used to live in AZ where it gets to 120+[°F] in the summer which is hotter than my battery ever gets even using QC from 1% battery. Quick charging won't hurt your battery any more than normally charging it will. There is a cut off for the temperature it will let your battery get before it drops voltage or amperage which will work whether the what is from charging or the environment you are in. As I stated above qi charging will make your battery heat up more (in my case it does) I will post screenshots to back that up if you would like.
Lastly no one is expecting a battery to last 1-2 years without losing capacity so why worry about it? Your phone is warrantied for at least 1 year (I have moto care on top of the regular warranty) which will cover any battery issues. There's no need to panic or make an issue out of nothing.
Now can we please let this argument die? I keep seeing it and its getting rather old. Even if it does (which I'm not saying it does) degrade slightly faster its not a big deal for the aforementioned reasons. Let's get back on topic here people
Hi! I bought a wall charger from Aukey that allow to charge up to 3 devices at the same time, what is great since I'll be able to charge the phone and the tablet at the same time! According to the manufacturer the charger is able to adapt the output to the needs of the devices! So my question is, can I use this charger to charge the GWR without damage the watch, since the output of the original charger is only 0.85A!
I think it should be fine. I have used my charger a couple of times without issue for my GWR and now my Huawei

I've been using an Aukey quick charger for a month now and no problems whatsoever. Normal charging times obviously (blisteringly fast on S6 however)

So I don't need to hurry about the output current, or in other words, get the watch too much warm and reducing the battery life?

It is completely fine. The charging circuits of these devices (watches, phones, tablets etc) takes only what it is allowed by the limitations set to the charging IC circuit when supplied with 5v power over USB. I have an USB amp meter and the GWR barely uses half of the original chargers 0.85a capability. I've used my OnePlus One charger (a high quality 2A charger) to charge my watch as well occasionally, which also charges my Nexus 7 2013 regularly and that never takes more than 1A~ from this as well.
I've been using a Aukey Charger for a couple of months and no problem so far. The current regulation is supposed to be made by the device, not by the charger anyway ...
For those who wonder, I also checked if our G Watch R has QC 2.0, but it doesn't. It still charges at 5V on a QC 2.0 slot.
Everything I can find says that the only way we can "quick" charge is with the official OP Dash charger?
anything else we use will only do normal/slow charge?
As far as I know, this is correct. Dash Charge and Quick Charge are entirely different technologies that are used to accomplish a similar goal.
I believe that you can still use the QC charger, but as a normal charger. Just like Dash Charger when plug other phone in, it just turn into normal charger. But there is a potential problem here, Dash Charge works by pumping a lot of amps and keep the voltage the same, while Quick Charge doing it vise-versa, and QC is a technology develop by Qualcomm, meaning the SoC itself in the OP3/3T would support it, it just the rest of the hardware do not. If for whatever reason, the QC charger still provide more voltage than 5V, it could damage the phone. I don't know what is the max voltage the 3T can take before it get damage. If you want an official answer, get it from OP.
USB C plugs will work from what I've read, but nothing will quick charge but the Dash chargers--just normal chargers. Which is fine for me honestly, I use a regular charger at home (overnight) and keep the dash charger with me for work/etc where I need to pump juice faster.
That's dumb....I was hoping for quick charge 3.0 support plus dash charging. GAH! I might get a dash car charger then....I use my phone a lot. I like being able to charge fast while I use GPS. I use GPS a ton. And my new portable charger....QC 3.0.... That part of it is useless now.... grrrrr, but is this verified?
Maybe we all should contact Anker, and ask for Dash Charge support. What I very want is the multi ports car charger with at least one Dash Charge. But such charger do not exist anywhere.

Would love to see some 3rd party support.. in principle the idea of moving this function outside the phone seems appealing... but I hate only having 1 vendor to buy from... and I'm not even clear.. can I use the Dash charger to charge my non-OP devices? (ie. reducing the # of gizmos I have to travel with).

Yes but it won't "dash" charge them.
I asked the same sort of question here: http://forum.xda-developers.com/showpost.php?p=69856748&postcount=5
I've been using an anker QC 3.0 charger on the OP3T and it charges fine.
it doesn't get hot, doesn't say it's fast charging but it seems to charge at a reasonable rate nonetheless.

Thanks for that.
I'm interested in knowing if the voltage/amps/whatever are going to mess with the OPO battery that's not rated for the Q3.0.
Does anyone know if USB-PD charging would on the 3T? I ask this because as a nexus 6P user i have a number of charging accessories, and USB-PD is baked into the USB-C standard. So logic would dictate assuming the 3T conforms to the standard it should be able to charge at 5V 3A, which would be slower than dash charge, but quicker than the average charger.
Have a good one!
I have a 7 port anker usb3 hub that has 2 charging ports and a 2amp 12v wall wart. It charges just as fast as the OP3T charger. Full charge from 50% after work in under an hour.

Just got my Note 8, second hand from swappa. My last phone was a Note Edge (note 4 variant). I remember back in those days (2014) people would say that fast charging was bad for battery. I did notice as time went on my batteries would get super warm. I have a zero lemon I'd quick charge
With newer phones like the Note 8, do I need to worry about how much I fast charge or is that no longer an issue. I definitely like my phone charged fast, who doesnt but are there bad effects to this anymore or have they mostly been ironed out. And I heard somewhere battery discharges slower with normal charge as opposed to fast charge?
Well, fast charge is really useful when, as its name implies, you need to recharge quicly for whatever reason, but giving it some little thinking I supose that fast charge has some caveats, if not, why this fast charge is not the standard way to charge? You see, there must be a very good reason for that, I prefer wireless charge btw
Yes, fast charging will always be bad for a lithium. However there are different forms of fast charging. The stock power supply switches 5 volts, 9 volts or even 12 volts! These should be avoided. With USB C you can get high wattage chargers like the MOTO 15 that will fast charge your device on the 5v rail while using the native USB C high wattage rail acceptance. Or 5V 3A, your phone will say fast charging and turning the feature in the battery settings won't change because it's only disabling 9v and 12v rails.

I would think that's overkill, 15 watts is plenty.
