I did search through the forums and didn't find anything that applied to the issue I'm having. I bought a 6P off Ebay for a good price, but it didn't come with any accessories. I don't have a C-C wall charger, but I did buy what I thought was a decent one with a C-C cable for my car. The charger is made by Satechi, and the cable is made by Belkin. They both specifically say on the box that they support fast charging, the cable up to 60W, the charger up to 36W. When I tried multiple amp monitors on my phone it only said that it was hooked up to a 1500mA charger. Plugged it into my USB battery pack which has a 2.4A port, same thing. Now, in my experience with computer hardware most of my hardware problems are generally software problems, and I'm wondering if installing Lineage on this thing has eliminated my ability for fast charging. I've done lots of searching (my Google-Fu is terrible) and there's no real mention on if fast charging is up to the hardware or software. Does anyone else have some experience with this and can maybe guide me through some things I can look at?
I know that ampère (app) says Max 1500mah too when I'm connected to my stock charger, but the charge rate goes well over 1500 mah (around 2500-2800 or something). After hitting 60% or something it slows down. I also know that lineage os on the nexus 5 says "charging slowly" on the lock screen, while the charge rate is normal.

I had a similar thought so I drained it to about 25% and then charged it back up. Fastest charging rate I saw was 1250mA.

It's hard to say whether the app, charger or cable is letting you down here. The 6P charging cycle has many steps and it will only pull maximum current from empty to about 30%. Next time you discharge the phone, pull it down to the single digits and then check current again. My stock charger will put out 2.7+ amps when the phone is fully discharged. (I used Accubattery). What you should also know is that the phone will continue to charge for 45 minutes or longer even when the phone says 100%. If you are interested, you can read more in an early Anandtech article. Scroll down to the "Charge Time" paragraph/graph. There is a lot of misinformation around the USB-C standard, and ton of crappy chargers and cables that do not meet the USB-C standard or make claims that independent testing does not back up. A Google engineer named Bensen Leung has been lab testing cables and chargers to try and provide some clarity. For car chargers, he currently favors the Nekteck 5.4A . Lastly, there is much more discussion on chargers and cables in the Accessories sub-forum.

Well, I tried it with the app you mentioned and it said (at 9%) at I averaged a 1350 mA charging current. I almost need to find a charger belonging to someone else that works on their own Nexus and then try it on this one.
@Caboose27
Good you tried a different app to rule out a particular app. My guess is that one of your components is not living up to it's claims. Look for Benson Leung approved cables/chargers and you won't be disappointed. Have a look through the Accessories sub-forum to find good stuff tested and endorsed by other folks. Good luck to you, and welcome to the exceptional Community of the N6P. You chose a good device.

I did look through the Accessories forum, and I found a post about a USB charger that's basically exactly what I'm looking for. But it was a year old and he never wrote if it worked or not, hence me starting this post. I appreciate your input though. Most of the stuff on the sub-forum is about wall chargers, and I'm specifically looking for a fast charging car charger.
See https://www.qualcomm.com/media/documents/files/quick-charge-device-list.pdf (the only not so funny thing is that it doesn't mention Nexus 6p)
Will receive my car charger tomorrow and I only discovered this document today.
Lucky me, the charger is mentionned So is your Satechi.

It doesn't mention it because the Nexus 6P does not support Qualcomm's QC3 or QC2 at all. Hopefully the car charger you bought (you didn't specify) has a native USB-C port or a permanently attached USB-C cable that outputs 5V/3A. Otherwise your QC3 charger will only output a maximum of USB-A which limits you to either 2.1 or 2.4A. A review and test results of many USB-C compliant accessories can be found here.

It does have a USB c cable and outputs at 3A.
Good spot on 6P not supporting QC while chip is a Qualcomm
Haven't seen many reviews. Will give feedback if it exploded.

This might be more than a little geeky, but perhaps someone with an knowledge of how the hardware is addressed by the two different operating systems can help me out with further information.
I have been investigating the behaviour of the HTC HD2 whilst charging as I wish to make a car charger and also modify a USB port on a device to fast charge my HD2 (ie turn an O2 Joggler into a charging station).
So I have been analysing the fast charging behaviour of the HD2.
Ok so far? Here is what I discovered.
The HTC charger when connected to the HD2 charges the device with just under 1A at 5v. The current that is supplied is limited by the HD2 itself.
On a standard USB port, the HD2 charges at just below 1/2A, the limit to what a standard USB port is spec'd to deliver.
Here is the interesting bit.
The Data lines (D+ and D-) of the USB cable are supplied with a 3.3v (Approx)) signal from the HTC wall charger. This tells the HD2 that it is safe to draw the full 1A line via the USB cable.
Now on Windows Mobile something interesting happens on the Data lines when the phone is connected. The Lines hold high at 3.3v for 250ms as seen here:

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
After that is drops back down. It is even possible at this stage to disconnect the Data lines and the phone continues to draw 1A of current...
Now when Android is running on the HD2, the charging behaviour is different. The Data lines hold high at 3.3v for the whole time that the charger is plugged in.
Clearly under windows control, the data lines are somehow being either switched off at the charger or more likely being sunk to ground at the phone end. Quite why, I'm unsure...
My questions:
Can someone with knowledge of how the OS's operate shed some light on this?
Is there a risk of damage to the data lines from charging under Android?
Should the android drivers be re-written to emulate this windows behaviour?
Should I perhaps get a life??... Ok I think I know the answer to this one!
I am using the Darkstone Sense build and Miri 6.5 V17 FWIW

The DSO Nano...
http://www.justblair.co.uk/seeed-studio-dso-nano-pocket-digital-storage-oscilloscope-review.html
A little limited, but cheap and very portable, perfect for this kinda stuff...
AFAIK even directly shorting usb data pins work with high current charging. (You can even slide a thin metallic foil to the connector) Some people use chargers with standart usb ports with charging cables that have data pins shorted. (as standart chargers don't have data pins shorted, even if they can provide more then 1/2A)
I have charged my phone under Android a lot times, nothing bad has happened yet. I have used properly/originally shorted microusb chargers from HTC, Samsung and Motorola. All these three chargers have data pins shorted from the factory. Android is able to differentiate AC charging from USB charging.

Thanks for that, though I am confused. My experiments show that the Data Pins are held in a high state (3.3v) to initiate charging to the HD2. ie the phone decides on the rate of charge according to whether a voltage is present. I am interested in what pins are shorted and why?
I have a test rig now set up, so I can test this for sure, but I am not sure if shorting out the charger (ie connecting data to ground?) is going to be good for its health.
My original curiosity as to the difference between how WinMo and Android instruct the charging circuit still stands.
It is geeky indeed, but I have to say, wall charging under android is soooo much faster thatn on winmo. About twice as fast.
Q: Is that bad for the battery life ? (it may also heat a bit as the result of the fast charging.

Hmmm... Are you sure?
Reason I ask, is that the amount of current drawn by either WinMo is exactly the same.
If what you say is true, WinMo must be "loosing" some of the amps during the charging process. I am unsure as how to visualise this with a scope though it should be reasonably possible to measure the time taken to charge a battery. I have not noticed a difference, however I put mine on charge overnight usually so I am not really aware of how quick or otherwise the charge takes
Interesting thing to test
Justblair said:

Hmmm, well maybe not twice, but I sat down and checked, it can rise up to 1 % a minute in AC charging under Android, never seen this in winmo.
I have also noticed (with the built I am using now) that sometimes I let it charge the whole night, and in the morning, I can only see it charged to 93 or 94 % and not increasing anymore, somehow roofed to 93%, then I unoplug it and plug it back and it start to go up to 100% again at a fast pace....
Strange indeed, I guess not everything is sorted yet...
I have read on the forum some other members saying that charging on android might be damaging to the phone. I'm a little worried about this, but it seems like no one knows if it really is. I have been switching to winmo to charge at night just in case.
I suspect that charging under android shouldn't actually be different, isn't at least some of this stuff handled at the hardware level and not at OS level?

The only way it could damage the phone is if it was overcharging the battery (charging beyond it's capacity), however the HD2 has a chip that prevents this (google ds2746).

People should be informed that there is a risk, if there is one of course. I mean appart from the "Use at your own risk, you may brick your device... " and all that stuff that is true by the way.
But in the worst case it can only reduce the life of your battery ? And worse case scenario you buy a new battery if capacity it too crapy ? (not extremely expansive).
Please Post if someone has an idea.
Is there an app outhere that check health of batteries and capcity compared to "as new" as we have for laptops ?

Of course you are right....
I misunderstood what you meant my shorting the pins... Yes joined together the two data pins indeed trigger the fast charge. I have replicated it on the bench.
WM driver checks DMinus level and if it high assume this is AC charger, shutdown USB totally and enable fast charging.
Android driver actually based on google nexus driver and already have this feature implemented. seems it's doesn't shutdown USB.
other device, like desire and nexus also use this kind of AC detection.
I dunno if it can harm device.
A new battery is 10 bucks. A small price to pay for running android before its 'prime time' ready, if theres something wrong. Plus the Devs know more about this stuff then I ever will. I trust them.

The Galaxy Note 3 charger is 2A. I tried a Nexus 10 fake charger (2A verified, uses 15W from wall socket @2A with the Nexus 10 to provide 5V/2A (10W, not measured)) while Sony original 1.5A charger uses 9.3W to provide 5V/1.5A (7.5W, not measured). Connecting the Nexus 10 charger to the Xperia Z3 compact it uses only 9.4W so it only take 1.5A or less even with an high gauge USB cable.
Therefore I would say that the phone never uses more than 1.5A no matter what's the charger.

Usually LiPo/Li-ion batteries support 1C charge without problem (as long as the charger slows down at the end). The capacity of the Xperia battery is 2600mAh, therefore 1C would be 2.6A, with a 2.1A or 2A charger you encounter absolutely no risk. Also even using an higher current charger, every phone (with a lithium based battery) integrates a charge regulator which will limit the maximum current according to their specifications. Therefore higher amperage is not a problem as higher voltage would be, it's more the highest current the charger CAN provide, not it actually provides.
It will charge even quicker, as the phone(Z3 and Z3 Compact) is Quick Charge 2.0 certified, you will just need to get a charger that is Quick charge 2.0 certified as well (i.e. Moto Turbo Charger). Feasibly, it could be charged in 45 mintues form 0-100%.
The charger will be my next purchase.
Not sure what's considered fast or slow when it comes to charging, but just using a generic USB charger with wall plug-in adaptor (as I do with all my phones without issue), I'm fully charged after a complete drain in about 2 hours. However, if there is some magical charger that can do this in 45 mins, I would totally invest in that!

Nice. I'm assuming there must be an 801 variant. Let us know how well it works when you do get one. For now I don't mind the slower charge since I leave my phone plugged in overnight, but I can forsee occasions where I would need a speedier solution.

I think he was referencing 900-1100mAh vs. 1500mAh of the stock charger. So to correct it there is absolutely no difference from a technical point of view between USB or magnetic port, there are not more less losses assuming the quality of the cable is the same, it is just a different plug. The magnet only holds the plug, the connection is wired and not inductive therefore efficiency is.the same.

This is Apple BS to explain the incompatibility of their iPhone with most chargers on the market at the time. The phone does not need to identify the charger max amperage at all,the charger is simply a 5V DC power supply with a defined max amperage like a wall outlet provides 110V or 220V AC at max 10/16/20/32A. The charging circuit of the phone does all the job: transform 5V to 4.2V and then regulates the amperage going to the battery at constant voltage. There is a difference with a wall outlet though, if the rating is lower than what the phone requests then the charge will simply be longer and the charger will not burn (at least if it is lawful).

It definitely does need to, that is, if you want your phone to draw more than 500mA. USB standard does not allow a device to draw more than 500mA from the port, and all phones conform to that. That's why it charges slowly if you plug your mobile phone into a computers USB port, the internal charger circuitry inside the phone limits the maximum current "ceiling" that it will try to draw to mere 500mA.

You are correct on the defined max amperage part. Every DC power supply has it's maximum current limit, just like ordinary computer USB port (which can supply max 500mA, if you step higher than that, the current overload protection in the computer shuts the port down (and windows will give you an error about a power surge on USB port X). That's precisely why a phone must identify if the power supply that it is connected to can give higher than 500mA current, as to not overload it.

Yeah, many cheap ones will overheat (shorten the lifespan of electrolytic capacitors, etc) and even burn. And even some that are not cheap will burn. Others will be periodically shutting down by internal thermal protection, then turning on again after it cools down, this is not good either.
If you use a magnetic charger then the phone loses the ability to identify if it's connected to a computers USB port, or a charger that can supply more than 500mA. And in this case it will stay on the safe side and will not try to draw more than 500mA (charge slower) from the port.
As for the identification, you can check that pins 2 and 3 are shorted in the charger's USB port, that is how the phone "knows" that it is connected to a charger with high current ability. You can get some spare USB cable and make an experiment, cut the wires that go from pins 2 and 3, and you will see that the phone will limit the current to 500mA.

As for the identification, you can check that pins 2 and 3 are shorted in the charger's USB port, that is how the phone "knows" that it is connected to a charger with high current ability. You can get some spare USB cable and make an experiment, cut the wires that go from pins 2 and 3, and you will see that the phone will limit the current to 500mA.

Experiment done: I beg to differ, the phone draws 1.5A from the magnetic port, see attached picture (it is the current drawn from a 2S battery at 7.62V so roughly 1.5A at 5V. Also this circuit can provide 2A at 5V which means that the phone never draws more than 1.5A no matter what the charger is.

The fact that data lines only indicates it is a charger and not a computer, data lines at not shorted but connected to a certain resistance function of the amperage of the charger if they follow the apple scheme.
Hi guys,
I have an D6543 (Brazilian Model), there is no difference between D6503.
I checked the Qualcomm website a lot of times, and Z2 is in compatibility list: https://www.qualcomm.com/products/snapdragon/devices/all?feature=Quick Charge 2.0
So, I purchase the Tenergy Quick Charger 2.0 at Amazon, and for my surprise, it's not working at all. Only normal charging.
I tested at 1%, and in 30 minutes only 11% was charged, VERY, VERY slow.
The light indication at charger is saying that is on normal charging.
I'm really frustrated.
Fastcharging is disabled on xperias for safety
Charging should be between 1-5 hours even without fastcharge
My z2 only take around 2 hours to fully charge from 1%. Just using the stock plug charger.

It charges at 1500mAh using the factory provided charger and trying to go beyond that isnt safe at all.

I don't know why. Z2 has the Snapdragon 801, which is compatible with Quick Charger 2.0, as Z1 was compatible with QC 1.0.
LG G3 also has the 801, but LG does not enable the QC, that's why it is not at Qualcomm's website. It's weird, because Z2 was recently added to the list, and the main product page says it's compatible.
In the end, I just lost money because their poor support and information.

Not exactly poor support, if its safe to use and certified safe to use sony would have put it in the features list on their website but it wasnt there when i bought the phone nor when i last checked.
As said check my reply
The device charges at as fast as it safely can with the factory provided charger
I'm using envi rom.
I have a normal 2,2A usb charger.
When I use the usb port to charge i have really slow (6h from 0 to full charge) to reasonable charge time (3h from 0 to 100) depending on the used cable.
But when I use the magnetic aftermarket cable than I get insane charge time, only the last 10% from 90 to 100 is not fast but it certainly uses 2A as it is from 0 to 90% in about 90 minutes.
The phone gets slightly warm but far from the temperature it gets with intensive usage and the magnetic connection gets warm too, but nothing alarming imo.
The full metal and glass design makes heat diffuse very fast.
That sucks I'm coming from a one plus one and the charger was very fast.

Xperia Z2 and Z3 supports Quick Charge 2.0.
You need charger which supports Quick Charge 2.0, though.
http://weekly.ascii.jp/elem/000/000/223/223383/
This site is in Japanese, but it says you'll get 13W when you charge with charger which supports Quick Charge 2.0 and with normal charger you'll get 10W.
Normal charging is already fast enough, so you won't notice big difference.

Either they know nothing about electronics or they cannot calculate ^^
1. it should show 9W..... 1.8A x 5V so their meassurement device is not exact (hell, these Wallplug meassurement things are made for 220V ! so you measure 0.045A you can't expect them to be realistic, they're for up to 2000W not so low values.)
2. 9V x 1.8A = 16.2W but this is wrong again as the Quick CHarge 2.0 speccs are up to 4.5A for 9V
So if it really is charching with 9V it only uses 1.44A
Oh... and btw the Stock Sony Wall charger EP880 only has 5V 1.5A
Let's hope some people who know what they're doing are gonna test the Z2 or other phones with Quick Charge 2.0

I'm unsure about the battery but this is why QC 2.0 utilizes a higher charge voltage. Also why in computers, all high current devices now run on the 12v rail instead of 3.3v or 5v, because high amperage at low voltage would damage cables and connectors. If we had expensive graphics cards pulling 400w at 3.3v there would be a huge problem with heat and necessary wire size. There is more resistance in metals with high current / low voltage vs. high voltage / low current and this is what can damage the USB port.
This is also why at 120v AC we have issues running high current draw appliances vs 220-240v circuits.
Also why high voltage is more fatal, because it travels more easily through our skin, and etc.
I contacted Qualcomm by email, and they replied to me after a few days.
Xperia Z2 officialy does not support Quick Charger 2.0, only in JAPANESE models.
They updated their website, and removed the information, that's sad.

FYI guys, Sony Brazil sells Z2 and Z3 with Smartband, so, our OEM charger has only 0.8A :crying::crying::crying:

Hello,
quick question: is it safe to charge our Z2's by S5 charger - 5,3V and 2,1A?
i dont get this. If the stock charger is 1500mA and the batery is 3200mA it should take only 2h10 to fully charge(more or less). But mine takes like 3h (brand new phone, charger and cable, all stock)

yes its 1500ma with a 3200ma battery but concider the cpu. your phone is awake for 25% of the screen being off so it should take a over 2hrs10m to charge unless you have xposed amplify installed.
I've done some testing on the best ways to charge the Nexus 9. Here's what I've found...
a. You'll want to upgrade your kernel.
The stock kernel for the Nexus 9 does not support charging over 1.5a, I'm using Elemental X which supports up to 2a.
b. Use a charger between 1.5-2a.
I'm using the Insiginia rapid charger from Best Buy.
I've tested 4 different cables to see the amp output from the charger with the new kernel using Ampere. The stock charger from the box, my Moto G LTE charger, an Insignia charger and a generic charger from ebay. The results are as follows...
Insignia Rapid Charger @ 5v/2.4a
I read the readings with the screen on 40% brightness and let them each sit for 60 seconds.

Min is the minimum amperage the cable hit, max in the very maximum and avg is the average at which the output sat around.
As expected, the stock usb cable performed the best, while the generic charger was very unstable and wild (I probably won't use this charger anymore as a result).
Interesting about the kernel.
Also your title says cables then you talk about chargers. Cables can also make a big difference in how much power your device gets. What cables did you use?
*EDIT*
Ahhh i miss understood. you where switching cables not chargers.
you probably were seeing this http://lifehacker.com/cables-can-significantly-impact-the-charging-speed-of-y-1532784722
Thanks for this. Was wondering how much the cables mattered.
I tested my stock charger and cable. The average amps are 850-1100 mA. It's mostly around 980 mA, and the max I've gotten is 1160 mA. Doesn't seem to go beyond that.
I also tested a nokia cable with the stock charger that is 1.2 meters and got quite different results. It charges with the average amps at about 450-550 mA, with it mostly at about 500 mA. Max I got was 740 mA. Not using that cable again...
Kernel is FireIce which supports 2A charging, and brightness was at about 40%. Voltage was read at about 4.02-4.11V for both.
Gonna have to find a charger with a 2A output.

same here. the best cable/charger combo i've tested is the stock samsung charger and 3' cable (not sure which box it's from since i've had so many galaxy devices, but they're all the same). the 5' cable hits about 1400. using a monoprice 6ft cable does just as good as the 5' cable. i have a 3' monoprice in the car but too lazy to get it to test it. the best generic cables i found are these:

Wow, those are pretty inexpensive. Thanks for posting
Not a surprise. Many (most I suppose) of the cheaper cables simply dont have thick enough wire, too much resistance. For decent and cheap cables I like the Amazon basics cables. The newer USB3 versions have thick gauge wire so the 6 footers charge at full speed even with devices that support high amperage charging.

I'll keep that in mind about the amazon basics brand. Im just using a cheap china made brand, (i dont know what brand) and they charge pretty slowly, but it's alright. If the device is dead, I'll plug it in, and it'll be charged by morning. I don't really need anything too much fancier or faster than that.
The "basics" cables are a real bargain. I am very careful about the cables I use these days after my wife used a cheap cable on her N7 and it shorted out on the connector and roasted the pins on the device. Not sure how that happened but I suspect a very sloppy fit didn't help.
I'm using a monoprice cable (6ft i believe) with the oneplus one charger, and it works perfectly. The monoprice USB cables are among the best I've used; they're durable, reliable and the springs seem to keep their tension over time, something I've found that cheaper USB cables can have trouble with.
To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Google Pixel 3 can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!
The Pixel and Pixel 2 used to charge "fine" through a PC port. The pixel 3 charges extremely slowly. For example my Pixel 2 would be at 50% battery and using the USB port on my car it would be close to 90% when I got home. Under the same situation, the Pixel 3 would only be at 55%. Same problem using the PC port. I know I know it's NOT supposed to be fast charge but I am only stating the facts and differences. Stock charger charges fine.
Pixel 3 charges very slowly on my existing 2.4A (per port) multi usb charger. Clearly it's not a PD charger, but it always provided enough juice for my nexus 5x to charge quickly. Clearly the pixel 3 doesn't like it.
Can confirm this also. Ampere indicates that it pulls less than 200mA on any non-USB type C charger. This is different from my previous Pixel 2.
With Samsung fast wireless charger, s9 goes from 20%to 100 in less than 2 h, pixel 3 charged only 25% in 2 h....... Charging speed is awfull if you don't use Google chargers

I'm not an expert at this stuff and certainly might be missing something but charging at 1000mA from a 1A charger should be physically impossible. Wouldn't that be 100% efficiency?
Yup.. Charging is too slow.. Infact, the charging time estimated (which is shown on the lock screen when the phone is being charged) is also wrong.. May be it gets adjusted over time...

The estimate is adjusted over time. To my knowledge, all fast charge technologies are able to charge much quicker when the battery is low, but then slow the charge down as the battery approaches a fully charged state/heats up. The estimate would simply be a guess, since they likely are, app status, ambient temperature and battery condition dependent.
This can be seen in the graph on xda's quick charging comparison. Note that all the technologies start out quite fast but eventually taper off. Also note that USB-PD is the slowest (most conservative) of the technologies after the battery gets to about %40 charge.
https://www.xda-developers.com/charging-comparison-oneplus-huawei/
I would add that my new pixel 3 does appear to charge a little slower than some of my previous devices, however I've got several devices that use USB-PD so the versatility of USB-PD and ability to use one charger across my devices more than makes up for the extra 30 minutes or so of cellphone charge time. Guess everyone's expectations are different.
"Fast charging" on the Pixel is via Power Delivery. This is only possible over USB-C; PD can negotiate higher charging rates by increasing the voltage. This is not possible with PC type A ports; type A is rated for 5v, 3a max.
Qualcomm Quick Charge does adjust voltage and uses type A ports, but it uses the data pins for rate negotiation, while PD uses pins unique to USB-C.

No. The charger is able to deliver 1000mA, but the total power delivered to the device will be less than it draws from the mains supply (the difference wasted as heat).

The phone doesn't like to charge fast if the battery tempeturature is "high" (higher than 35 ºC). It's just a very agressive charge trhottle. Try charging again but in a colder weather or room.
It was my experience.
The charger that comes with the phone is not fast charger?
Got my phone yesterday and when I charged it, it said it's slow charging....
Edit
Second charge was fast charge according to info on screen.
After Dec update, the PC port charging is normal, not rad, not slow but normal. Problem fixed.

I already posted regarding strange behavior of wireless charging: https://forum.xda-developers.com/showpost.php?p=78315849&postcount=73:
Before I've got original Pixel Stand, I used generic wireless charger. No surprises, it chargers P3 slowly. But there is more. Sometimes it doesn't charge P3 at all. Way more strange, that almost the same behavior I have with Pixel Stand. After some days I began to suspect there is a regularity - the charge at full speed works with at least 85% of charge at phone. If the charge is lower, the possibility the charge would be at rapid speed is pretty low. It can claim it charges rapidly, but in fact it doesn't charge at all, since the charge is going down at the same rate as phone out of any charging. I definitely have relatively small statistics and can not say for sure that 85% is a "red line" for triggering wireless charge start (regardless of speed in my case). Today even at 91% phone battery wireless charging at Pixel Stand didn't start at all (with "charging rapidly" announcement at screen and slowly discharging phone). Other functions of Stand work pretty good regardless of what's going on with charging. I didn't contact Google Customer Service since the results are unstable.
Click to expand...

In case of regular charging through the USB-C cable from native Pixel charger I've never had any problems. But wireless charging even with original Pixel Stand doesn't look good. At the generic charger even after Dec update charging goes south - not charging at all or with original Google wireless charger just like at screenshot - rapid charging in day and a half. It's better, than no charge, but for $79.99 for original Pixel Stand it has to be faster.
