Like I mentioned earlier in my other topic (sadly we can't edit topic titles)
Here is the proof that the Z2 does support QuickCharge tech. Now all we need to do is find the QuickCharge certified adapters! Lets get to work guys!
http://www.qualcomm.com/snapdragon/blog/2014/06/04/quick-charge-20-has-arrived
Just a heads up, a notice from that blog post:
Contain the hardware necessary to achieve Quick Charge 2.0 charging speeds. It is at the device manufacturer’s discretion to fully enable this feature. A Quick Charge 2.0 certified power adapter is required. Different Quick Charge 2.0 implementations may result in different charging times.

Emphasis mine. So while the hardware support might be there, it does not necessarily mean that the Z2 has it enabled yet/properly.
Also, finding good information on those adapters mentioned wasn't easy. Let's hope they hit market sooner rather than later.

Sony is enabling them in the very next update, or so I heard.
Right now finding the charger is the issue.
Here's a review by someone with a Z2 and one of those chargers :

Dude, that's a 1.8a charger from what I read on the translated page. You wanna talk about fast charging, pick up an Oppo Find 7 with VOOC... 4.2a and it uses it!

Yes, 1.8A, but also at 9V DC, which is the key difference here. Quick Charge 2.0 apparently supports charging at higher voltages (9, 12 and even 20 in some cases).
Information regarding ChiPhy 100, an IC that implements Quick Charge 2.0 and describes the basics, including voltages supported by different classes of devices:

Quoted from http://www.qualcomm.com/snapdragon/blog/2014/06/04/quick-charge-20-has-arrived :
Here are just some of the devices and certified accessories as of June 3, 2014:
Smartphones
Sony Xperia Z2
HTC One (M8)
Xiaomi Mi3
Samsung Galaxy S5 (Japan)
Sharp Aquos Zeta
Fujitsu Arrows NX

The Z2 has the hardware required, but it doesn't mean Sony have enabled this or made sure it's working properly. With barely any available chargers supporting Quick Charge 2.0, we'll just have to wait and see. There's no reason why it should not be fully enabled, but I'm a cynic so I'd rather see it tested with the Z2 before I believe it

You what now?! So all chargers should just use the lowest voltage possible since that doesn't matter anyway?
Power is what matters! Power = voltage x current. Going from 5V to 9V while still pumping out 1.8A means the (potential) power output is almost doubled. Yes, you'll lose some of the power due to heat, but the power still increases a lot. This of course implies that the device can handle a higher voltage, which it seems Quick Charge 2.0 devices can.
Quick Charge 1.0 was device-only and therefore only 5V, but could boost the current output when the battery was (close to) discharged, which reduced charge time. Quick Charge 2.0 requires both the device and charger to support it and because of that it can also output different voltages, depending on what the receiving end supports/negotiates.
http://www.qualcomm.com/chipsets/quick-charge#features
Quick Charge 2.0 includes all Quick Charge 1.0 features and:
Automatic Input Voltage Detection (AIVD) and High Voltage Dedicated Charging Port (HVDCP) (Quick Charge 2.0)
Fully USB-interoperable backwards-compatible charging for >6V, 9V, 12V and beyond

Note the last point: you won't fry any devices if they don't support QC 2.0, the charger will just act as a regular 5V USB charger then.
Sadly, there are no numbers out there from charging a supported phone using Quick Charge 2.0. It would be very interesting to see which voltages and currents used at various stages throughout the charging.

So, let's go find a charger with 9V DC and 2 A output... and connect it to Sony Xperia Z2! Do you think that'll work good?

Of course not, and I've never claimed that either. If you have a QC 2.0 capable charger AND device, it can apparently charge at higher voltages, because both devices support it!. Nowhere did I state that the Z2 would be fine being hooked up to a 9V/2A "dumb" charger.
The OPPO Find 7/7a is already using this, although its called VOOC charging.
The charger is rated 5V == 4.5A

What is a "QC 2.0 capable charger" ? As I've seen that charger on that Japanese site, it supports 5V, 9V and 12V. Doesn't mean that the charger transfers power on all these voltage levels, right? It selects one of them. So I'm saying, we can select the 9V 2A and go try it. Or 12V 1.25A.
From the datasheet for that ChiPhy 100 IC, https://www.powerint.com/sites/default/files/product-docs/chiphy_family_datasheet.pdf:
With D+ and D- short-circuited the normal handshake between the AC-DC adapter (DCP) and powered devices (PD) as described in the USB Battery Charging Specification 1.2 can commence. After switch N5 has been turned on CHY100 starts monitoring the voltage level at D+. If it continuously stays above VDAT(REF) (typ. 0.325 V) and below VSEL(REF) (typ. 2 V) for at least 1.25 seconds CHY100 will enter Quick Charge 2.0 operation mode. If the voltage at D+ drops any time below 0.325 V CHY100 resets the 1.25 seconds timer and stays in USB Battery Charging Specification 1.2 compatibility mode with a default output voltage of 5 V
Click to expand...
Click to collapse
There's also an "output voltage lookup table" being used to select the voltage used, based on what the device asks for (see table 1 in the data sheet):
Code:
D+ D- Output Switch Status
0.6V 0.6V 12V N1 = N2 = On, N3 = Off
3.3V 0.6V 9V N1 = On, N2 = N3 = Off
3.3V 3.3V 20V N1 = N2 = N3 = On
0.6V GND 5V (default) N1 = N2 = N3 = Off
I heard about the Oppo Find 7's new charging tech, nice to see some more detailed information on it. VOOC seems to use what is essentially several battery cells and a battery pack with 8 contact points (not really any issue if it's an internal battery pack). It also requires a 7-pin USB cable it seems. Pretty clever, but requiring special USB cables is a bit of a downer. I'd rather have standardized cables and specialized chargers, but maybe that's just me

Thanks. Do you own z2 now and the pure gear? How about if you use the default cable from Sony,will it charge as fast? And also, can it quick charge at the magnetic port?
Sent from my D6633 using XDA Free mobile app
The oem cable won't charge as fast. In my tests it topped out alot lower. Get the one I listed first (pawtek). It charges very fast, no heat an is extremely solid.
I use it both on my z2 d6503 an z2 tablet.
The oem mag charger isn't as fast, even with puregear attached. That said I don't use the quick charge overnight, only when I need it.

Hey guys I'm looking for a car charger that will charge the phone while running google navigation. The current one I have cannot keep up. Basically the phone is using more battery than the charger is supplying so eventually even though it's charging it will die. Please help with some suggestions.
The higher the output amps the better, most online don't say.
This one has a 1A (1000 mA) which is the highest I've seen until now.
http://www.cellphoneshop.net/2usbcar.html
This says 2.1A.
http://www.amazon.com/dp/B004U4RF7I...e=asn&creative=395093&creativeASIN=B004U4RF7I
Here's one that has 1 of each (1A & 2.1A):
http://www.scosche.com/consumer-tech/product/1921
You need to be careful about using one too high for the phone as well.
The output of the wall charger that comes with the phone is 1A. Find an USB car charger that outputs 1A and you should be fine.
This will run Pandora&Navigation at the same time and still charge,but not by much. But a least it doesn't discharge.
*LINK*
The phones are only meant to charge up so fast. once you attempt to go over that limit, you risk causing damage to your phone. don't look for something with so much power it charges it in 20 minutes. it will kill the phone and battery.
Is 2.1A safe from charging phones?
Sent from my EVO 3D
I doubt the phone will charge any faster even if you get a 2A charger, but there are many chargers that only charge the phone half as fast as you possibly could. Some chargers only provide 0.5A (500mA, conforming to the PC USB spec) and some 1A chargers will only provide 0.5A because of the pin out on the connector plug... You can tell this is happening if under battery stats in settings it says it's charging from USB instead of AC. You could short some pins on said chargers to fix that but it's usually easier to find a proper one for $3 or whatever.
Even if you have a 1A charger you could manage to discharge faster than it charges if you're streaming music while using navigation for a while and/or you happen to be in a low signal area (which eats battery like crazy since the radio goes wild trying to find a better signal/tower).
I have the one in the link below. It is OEM HTC for the Thunderbolt, and has
2x 1A Ports. It keeps up with
Pandora and GMaps. My old charger would not (it was 500mA.) The cool thing is that both ports are 1A in a small form factor, and it has a white LED that illuminates them. It comes with a coiled cord which is well built.
http://www.amazon.com/gp/aw/d/B003OQUJRQ/ref=redir_mdp_mobile
Swyped using 2 cores and 3 Ds
I have the Motorola one, and it keeps up, and charges fast.

my tom tom universal one is the only one that ive found to come out at exactly 1A - 1.2A measured via current widget...
All the other brand 1A's sit at 350 - 600ma

You have no idea what you are talking about. The rating indicates the maximum current the charger is capable of. The phone will decide how much to draw.
Actually, the high rating is not enough. The charger should have a certain circuitry ( a resistor between data pins) to "tell" phone that it can supply higher current. 2.1A iPad charger doesn't have it because it was designed to communicate with iGadgets. It will act like a regular 500mA charger when connected to an Android phone.
A lot of the 1amp chargers that you see will still only charge your phone at 500ma. Unless USB pins 2 and 3 are shorted together (or have less then 200 ohms between pins 2 and 3), the phone will think it's connecting to a computer and only draw 500ma. I modified a few 1amp chargers to actually charge at 1amp instead of 500ma. See this thread:

Are you SURE you're getting the right result with the Current Widget? There's been quite a few threads on this topic and it doesn't seem that the Current Widget correctly supports our phone. Per that widget, I'm getting 400ma current draw normally - without running any active apps. When I use various chargers, that number goes up or down seemingly at random, LOL.
My most powerful charger, which provides 2A on one port and 2.1 A on the other - makes the widget report only 35 mA.
In short - I wish there was an app that correctly measures current draw on our phone, but I haven't found one based on multiple threads on the topic.
I use Battery Monitor Widget. I definitely see the difference between 500mA and 1A chargers. Some current form the charger is consumed by the phone itself, so it is not possible measure the actual draw from the power supply without an external meter.

I have the one from Sprint with the AC adapter in it that pops out and it works well. Granted it was a bit pricey, but, it does the job and the battery does in fact charge while using telenav navigation and listening to music through the stereo as well. Slowly, but, at least it doesn't discharge while being charged....LOL...

This is one of the few chargers that would power the Palm Touchstone reliably. There was an extensive thread at Pre Central on car chargers. Just make sure it's the SPN5400A like in the link above. Some other Motorola chargers have a lower output.
On the E3D it shows charging on AC.
Does anyone else notice that the charging on the phone is slow? The charge even goes down as i'm surfing the web with it plugged in. I'm currently using the sony power brick that came with it. I'm experimenting with different ones at the moment. Right now I'm using the Vita charger. But compared to how my Note 3 charges, this one pales in comparison.
Please provide tips if you have any. I am currently in the mood to purchase a car charger as well.

With that kind of voltage your ultra doesn't stay thin very long mate, definitely an error on the site.
You can't put more then 4.2V per cell. When it's more it will explode, in our phone there is one cell. My acer a700 have 3 cells, so that unit is charged with 12.6V.
You can charge faster by raising the current. Our cell is 3000mah, normally charged with 1500mah (0,5C). It should be fine to charge with 3000mah (1C). If the cell is decent quality it will take 6000mah (2C), but this reduces the charge cycles significantly. When the cell is inferior it will slowly starts to swell.
Everytime you double the amps the charge time halves (theoreticaly).
I would stick with 1500mah, done in 2 hours. There's always possibilty to charge.
This is what happens when you put more then 4.2V per cell into a lipo accu. In our phone there is a lion battery but this is almost the same. Lipo has a higher energy density.

I've been using different chargers and different cables, all at least able to charge at 1.5 amps. My results have been essentially the same: If I leave it alone, it charges rapidly, I'd say at about 2 hours and some change to full. However, if I start using it (especially on high brightness with lots going on) the charge slows down to a hault. This is the same on most Android devices. From what I've seen, the new snapdragon 800 chipsets are able to at least continue charging even through heavy use. Just not very quickly. I know the galaxy devices don't even charge if you use them heavily enough (with the exception of the Note 3 of course).

I've experienced this with another device, it was caused by a faulty usb cable. One of the wires inside was almost cut, there was only connection with a couple of the twisted core wires. 80% was cut, big increase in resistance.
I did a massive study on lion batteries last year, and found that voltage does have an impact. (pulled apart my battery and used various voltage/hz/amp input...
The major issue with the input is the heat. If you quick charge it for an hour then you are fine. But using quick charge, and then using your device will cause massive heat because you'll be charing it for more than an hour, and using your device uses CPU... (goes without saying).
Expanding and contracting the battery is what causes decay. The material inside the battery that holds the positive ions will crack and cause less 'hold' for these ions. This will result in less ions being able to be stored.
This also may also cause hardware issues flexing the internals.
result:
5v is fine, it comes down to 1.5 - 1.8 amps input... anything over that and you'll really need to check on the heat of the battery. There is also a sensor that detects input and output of amps. This sensor can get fried easily, so be careful not to wreck it!
What ever you do... DON'T put your device in the fridge or freezer if its hot. That will cause massive temp change, and mess with more than just your battery.

i have not noticed any difference. I think I just have to leave it along. Also isn't the quick charger from sony store the same one we get in the box? I'm thinking about getting the samsung charger from the Note 3, because the Note 3 charges hella fast and I can feel the charger box getting warm too.

It's very normal for a charger to get warm. You should watch the battery, that should not get warm.

I was thinking about plugging the Official Sony usb cord into my old Note 2 adapter because it's 2amps! the Note 2 cord also appears to be a higher gauge! I don't want to fry the battery on this thing, I wonder would .5 additional amps be ok?

I noticed that the plug that comes with the xperia z tablet is only 1.5amp, most other phones etc i have had have always been 2amp, i am just wondering if i would get a faster charge if i bought a 2amp charger, or could i potentially damage the unit if it is only supposed to have 1.5?
thanks

Thank you very much, i've just ordered a 2.1ma charger, i really cant understand why sony released this tablet with a 1.5ma charger as it doesn't charge it as such if you are also using it, but a 2.1ma charger would, maybe they were just trying to save money lol

No, not to save money; instead, to help the battery have a long life. Batteries that are charged with an amperage higher than their design ampere limit will not to live as long as batteries charged at or below their design ampere limit. So, charging your tablet's battery with a 2100 mA charger instead of a 1500 mA charger (per Sony's design) will shorten the battery's life.

Devices will only use what they want, you cant force for example, 4amps down its throat by connecting a 4amp charger. I connected it right to my galaxy s4's 2.5amp charger.
If its max charge current is 1.8amp, it will take that and no more.

Sites will always say they are compatible, as they wont your hard earn't cash.. But do you ever hear a manufacture, say it's ok to use a higher amp charger ??? No you don't.. Your better off picking up a portable charger that Sony recommend if your so worried about juice http://www.sony.co.uk/product/xperia-tablet-z/tab/editorialarticle2
Device will of course charge faster.
I don't expect it to have any measurable impact on tablet's battery life.
As with all chargers, voltage needs to be exact (or somewhere like 10% close - preferably 10% more not less), but amperage doesn't matter much as device will "suck" what it can anyway. Most chargers and devices nowadays have protection against "over"-whatever (overheating, overcharging etc.).

Don't fool yourself mate just Google "fast charger kill battery" there's plenty of users complaints..
There are varied opinions on the charger capacity and how good they are vs the demerits of using higher capacity chargers on these forums. I found the following article very informative.
Most of us charge the device while in use, so that uses some current which explains why we cannot get a clear understanding of how Li-Ion battery works. Hopefully the article give some clearer understanding of how the charger works. It is not as simple as "Battery will only take what it needs." The Sony charger is designed for 1.5 Amp for a reason. As for the life of the batteries themselves, most of us may not notice it because by the time the life of battery becomes an issue, we would have changed the device ( That's my opinion, not a scientific fact
Unless the device itself has some current limiting circuit inside, the higher capacity charger is bound to pump more current into the device. I do not know for a fact if the Sony devices has some such limiting circuit.

Electricity just doesn't work like that ? yes in normal voltage sources. Here we are talking about the charging of the Li-Ion battery.
Actually there are constant current sources used to charge batteries. True, there are no ideal constant voltage or ideal constant current sources. But the issue of pumping more current into a device is still valid unless the device itself has current limiting circuits inside and limits it to 1.8 Amps as in the example above. What I said was I don't know for a fact that Sony has a limiter inside its tablet for the charging circuit. It may well have. I don't know that. Just because most sources ( including our household AC supply) are voltage sources does not mean all sources are voltage sources.. Please check the battery university link I posted above. They also show the charging characteristics of the battery..

i bought a power bank with two output of 1A and 2.1A, but some time my xperia charger with 1.5A output is not sufficient to charge my battery and give me not charging error...
So i was wonder due what you says, if i should use 2.1A output? and how much on battery life it may effect?
Yes you should.
Every battery charging circuit "pulls" as much amperage as needed to charge a battery.
It's not something that will destroy it.
The charger can give out up to 2.1A, but will actually give out as much as the charging circuit "asks" (note the quotes).
Battery will probably charge faster.
Now if this does affect battery life, yes in the long run it could, as most batteries "prefer" (extensive use of quotes I know) slower charging. It all depends on how smart the charging circuit is and Sony has a good track record for their smart batteries (unlike Samsung for example - which I hope they fixed with non-removable S6 battery - but that's off topic).
If I go with, lets say the OnePlus Type C cord, will I still get the faster data transfer speeds/fast charging as if I were using a straight USB type C cable? It seems as if you use a cable that isn't type C on both ends that you wouldn't be able to take advantage of the faster data transfer speeds. I would assume this also applies to the fast charging but I'm not sure...

USB data speed will be the same because the Nexus uses USB 2.0 transfer. You won't get fast charging with a type C to type A cable. The type A only has the 4 USB 2.0 pins, whereas fast charging utilizes the power bus of the type-c cable (extra pins). So you will need a type c charger to get full charging speed.

The best you should get is about 2300-ish mA charging from type A connectors. Chances are you will get less. You will never get 3A from a type A port unless something has gone very wrong. See link for details.

Then why is the nexus engineer warning that C to A cables and adapters without the proper resistor will cause the device to attempt to pull 3 amps through the cable and burn up the charger? Seems he is saying pins or no pins it's going to attempt to pull 3 amps.

Almost any definite answer you get is wrong because Google has decline to say what the did and full testing has not been completed There are 2 parts to this equation.
1. What is possible to deliver over an A to C connection
2. What the phone will do
As to the first, yes you can get 3A over A to C. The problem has been that there just are not any 5V/3A A port chargers out there. Companies have been making "over charging' chargers for years. I've been able to get 2.6Amp to the phone over an A to C charger limited by the charger capability.
As for part 2, the first thing the phone does when a cable is attached is to determine what type of facing port it is attached to. In this case, it will be a Dedicated Charging Port (DCP). It will check voltage on pin CC and determine it is not a C port and therefore not able to negotiate a power contract in that manner. Type C specs then require it to draw no more than default power (500mA) for USB 2.0. If the device wants more current, it is obligated to monitor voltage on the bus to determine if more current is available. Hence, the device should never over draw the charger.
On the charger side, it will monitor the current draw and limit itself via a maximum current setpoint beyond which it will shut down. If the PD (Portable Device) is designed appropriately, it won't ever hit that because it is monitoring Voltage and the voltage drop will tell the PD to limit the current it is drawing to maintain vREF.
What is really unknown is what is the exact trigger for the "Charging Rapidly" in the lock screen. I get it under 3A.
Recommendation: Use A to C if you need multiple charger ports to support other devices. Don't get bent around the axle over getting all 3A. Use C-C if you only need one port. And in the future, the whole world will be Type C so your investment will last longer. But don't believe that 3A will be widely used. It is a design requirement in the Type C spec, but not a power standard in the USB spec. For example, the Lumia 950XL and Sony Z5 both are Type C and are reported to use Qualcomm Quick Charge 2.0. which top out at 2A at 5V (though can do 12V/1.5A).
Good Test - Get a Male Type C to Female Micro B adapter. Put it on the end of the Type C to Micro B cable plugged into the Google supplied Charger and see what you get!

The Google supplied type c to a cable says charging slowly when plugged into a PC which makes sense since type a should only pull 500ma from the port
The orzly cable that Benson tested shows me it says charging rapidly in that same port..
My other cable that I bought from a local electronics store shows "charging" only.. What does that mean? Is that a good sign that it won't damage up my port/charger/phone?

What this tells me 1st and foremost is don't go by what the lock screen says.
A USB 2.0 port on a computer motherboard is only going to output 500mA as you found out. A USB 3.0 port on a motherboard can output up to 900mA.
This is what Benson is saying. The Orzly cable is improperly designed such that it signals to the PD that it is 3A so I suspect that is why the 6P is showing Charging Rapidly.
Best way to test what is going on is to use a multimeter to test the current flow, but that means cutting open the wires or using a special plug with terminals. The next best thing is to use a battery app to see what the app says the draw is. This won't be as accurate and you should allow a minute for the device to come to full draw and the app to update.
Personally, I am almost 2 days on a charge where my previous phone required a late afternoon recharge so I am not all that keyed up over fast charging. It is nice, but as long as my phone is usable, not as big a deal because I recharge every night.

Then no worries. The Google Guy's whole point about the cables was that the phone might try to draw more current than the charger can supply and damage the Upstream Facing Port (read that as the charger). But any decent charger has overcurrent protection so neither the phone, nor the charger are in any danger.

I have to take exception to this. You keep saying people will be fine, there are protections in place, etc... But I have serious doubts if these protections are meant to be engaged every time a user plugs in. It's like saying it's OK to drive 120mph in a busy 45mph zone, because I'm wearing a seatbelt.
Further, I think you are doing a disservice to the community by posting that it's OK to use products that are clearly out of specification. If pulling more current than a charger could handle wasn't dangerous, they wouldn't be designed with some type of protection measures. As such, saying "neither the phone, nor the charger are in any danger" is patently false.

Look, I think all devices should be designed in spec and wish the USB Forum would more strictly enforce the specifications. But the 6P is obligated, when it can't negotiate a valid power contract which it can't do with a USB Type A port, to use default power and if it wants more current to monitor the voltage on the bus to determine if more power is available. Hence, if it immediately begins drawing 3A, or it does not reduce current draw when the buss drops below vREF, then the 6P itself is out of spec!
Both sides of the equation, Device and Charger have responsibilities and protections in place. If we were discussing plugging a 10A charger into a 3A device, I would be a little more concerned. But we are discussing plugging a 2A charger into a device capable of using 0-3A.
I also would be a little more concerned if dozens of people weren't already using these cables with less than 3A Type A chargers with no problem. The phones and chargers are doing what they are supposed to do.
That it's perhaps the single most disjointed rebuttal I think I've ever read. It also completely deflects from my point that you are giving bad advice and doing the community a disservice... But hey, I'll play along. Let's break down your reply into intelligible pieces to see if there is any sense to be had.

It is monitoring voltage, but it cannot know current ratings of the system it is connected to without a marker or sign post, which is where the out of spec cable is defeating this process.

That it's perhaps the single most disjointed rebuttal I think I've ever read. It also completely deflects from my point that you are giving bad advice and doing the community a disservice... But hey, I'll play along. Let's break down your reply into intelligible pieces to see if there is any sense to be had.
Agreed.
All components using licensed USB technology are obligated to follow specifications.
It can negotiate power with Type-A ports just fine using cables which follow specifications. The port and the phone are not at issue here, no matter how much you want them to be.
It is monitoring voltage, but it cannot know current ratings of the system it is connected to without a marker or sign post, which is where the out of spec cable is defeating this process.
So the 6p is out of spec itself when it is being told, by an out of spec cable, that it is safe to draw 3A?
Conviently forgetting the cable.
Well, that would be safe because the 10A device could safely provide 3A.
Which is unsafe, because MATH. 3 > 2

The USB Type A port has only 4 pins. VDD (+5V), D- (Data-)-, D+ (Data+) and GND (Ground). No way for a Type C device to use the CC channel to negotiate. It knows it is plugged into a legacy facing port.
The PD knows if more power is available or not by monitoring the voltage of the bus. If the PD trys to draw more power than the charger is capable of delivering, then the bus voltage will deviate from reference specs. As long as the charger is capable of supplying the current requested, it will be able to maintain the voltage within reference specifications. This is why the Tronsmart guy says his 2.4A will deliver 2.7A. It has enough margin capacity to maintain proper voltage over it's rated amperage up to about 2.7A.
I love my 6P and think it is the best Android phone on the market. But there are things that could be improved. I would like 2 fingerprint sensors, one back and one front, but if you are only giving me one on a phone this big, it would be better on the front. And 5V/3A was a mistake. It is a cheaper solution to faster charging. What does it say when the 2 port charger from Google is not 30W and they have no 15Watt (5V/3A) car charger available at all.

Great for Tronsmart. Not so good for users when they use that cable to transfer data or charge on a laptop, USB hub, or other data centric / non-charger type device and the current ramps up to 3A on a generic USB 2.0, 500mA, Type A port and fries something.
You're arguing that the phone should monitor what it could / should be able to pull from the port. I'm arguing that the USB specs are more complicated that that, which are the specs the phone follows, that the legacy ports and charging protocols follow, and is the current real-life facts of the situtation - not wishful thinking or hypothesizing of what it should or could do.

When you get a report of a port getting fried, will you please post it here. The more data we have, the better.

*sigh* People, don't use non-complaint cables, ok?
A Google engineer has publicly stated in several places that it is not safe and has even posted instructions on how to test for it.
PC Magazine even ran an article on it.
Hell... Common sense should tell you messing around with improper charging currents and voltages isn't safe.

*Sigh* This reminds me of all the negative Nexus 6P case reviews concerning the Laser Auto Focus by people without the phone or the case. They heard something on the internet and parroted it in review after review. Even the PC Magazine online entry is only a news items that repeats Benson's statements. No reporting of incidents, no comment from any company, including Google.
Has Google made an official statement? If this was such a big issue, does it not behoove Google to warn it's users?
I do not support manufacturers making out of spec equipment, including cables. Only that this is a whole lot of concern without a single verified case of incident.
The day 1 when I charged my google pixel 6, I had my heart stopped because while going to sleep I connected the charger and when I woke up the battery went down from 44% to 33% showing "connected, not charging" I thought this is it.
But then through out the whole day I was going through tonnes of videos and posts which confirmed one thing for sure that Google Pixel 6 doesn't go more than 22W on PPS charger. Finally fingers crossed I was going to spend on Anker 65W but then came across Belkin 25W Boost Wall Charger with PPS. My goodness the charger does what it does, charges 50% in 30 minutes and remaining reaching slowly in another 45 minutes which is enough and sounds safe to me.
I am posting this because many look around the internet for solutions like me, if I can contribute a little.
Amazon.com
It's very ironic. I was initially going to buy the official Google charger for the 30W despite already having a 20W one. I just bought another 20W charger in the Anker Nano one which also serves me perfectly fine as 20W is good enough; don't need the extra 2-3W ^^
Ayyyy! Snagged one too! It was half off bringing it down to $10!
For those in the UK the Belkin 25W Boost Wall Charger is currently reduced to £12.99 on Amazon.
Received the charger and it is as advertised. It peaked at around 25W and then settled at around 22.5W. Something to note is that the longer Anker cable I used to use drops it down to around 8.7W so the cable matters a lot.

33w pps and small it should be dropping againnfor black Friday.
Dropped to 4 quid in the 11.11 sale bf drops to 6
That belkin one decent tho
I bought the original Google charger 30w.Peek is 22 too.
I found a charger, more like power supply, that it gives constant 3a
Xfinity EPS-10
not sure if it will damage the battery though, I tried once and it charged it pretty fast... Someone can input something about this?

Did it charge at the same rate all the way to 100%?

It did. 2900+ ma constant.
It's a power supply for a xfinity box. They are not even expensive, like 15 bucks.
I was reading about chargers and power supply which the power supply is always the same but chargers have temperature sensors? Maybe was about something else....
I may be mistaken

Constant 3A means nothing. You're maxing out at 15W since it's not PPS. Higher current is not a good indicator.
Testing random power bricks is pointless unless you know it supports PPS.
A PPS charger can fluctuate between 1-4 amps and have a constantly adjusting voltage to maximize power output.
With a Baseus gan 2 65w charger I constantly see more than 20w charging except the percentage is high. I think this one has pd3 which supports PPS.
Do not trust Franco readings. Get an inline meter if you need absolute certainty.
You could very well be hitting those speeds since the charger looks to be compatible.

Understood.
Still, it got from 0 to 65% in like 40 minutes then I disconnected because I had to leave.. As soon as I receive mine, I'll do some stats and post them here.
I thought PPS chargers have a 3a max and is not constant, it goes up and down, depending on the battery itself.
The more amps that pulls, the faster it charges... Or am I wrong?
It's not correct. Power is current multiplied by voltage.
3A at 1V is only 3W. PD is usually 5V or 9V.
Google's can do 1.5A at 20V to reach 30W for supported devices.
For me, the more amps that pull the faster it charges... Voltage don't mean anything.
Voltage have great effect. Power is electrical current (amperes) multiplied by voltage (volts). For example 1 ampere at 5 volts is just 5 watts but same 1 ampere at 20 volts is 20 watts which is much higher. Different charging technologies have different approaches to send maximum power from charger to the phone but generally most use higher voltage to transfer power above 10 W because most usb cables do not support more than 2 to 3 A of current. Before charging the battery itself phone converts back the high voltage to low voltage suitable for the battery (usually between 3.5 and 4 volts). If you are looking at software programs like aida 64 or ampere - they read the current at this stage so this is why more current at that level means faster charging because the voltage is already reduced to what is needed by the battery. Generally you have something like this:
1. Phone and charger negotiate needed power and they way it will be achieved based on the capabilities of the charger, phone and cable connecting them. Let's say that they agree for 20W which is 10 V with 2 A current.
2. Charger transforms 220 V AC to 10 V DC and phone starts drawing 2A of power.
3. Internally in the phone voltage is transformed from 10 V to 4 V which causes current to rise to 5 A which are fed to the battery.
Here is a great analogy showing the relation between voltage, current, power and resistance using something as simple as water hose.

My 10ft type c to type c cable doesn't charge any slower than the supplied cable. However it is worth noting that anyone using a type a to type c will be limited to 15w.

It shouldn't damage it as charging is controlled by the SoC.
