My Pixel C tablet does not start to charge immediately when I plug it in to any charger. It registers that it is plugged in straight away, the battery icon changes straight away to the icon with a lightning bolt and the Ampere app registers as being plugged in, but it does not start charging. The battery information screen says 'Not charging' and ampere says the battery is still discharging. After about a minute this usually changes and the tablet does start charging, but a couple of times it has not charged at all while registering that it has been plugged in for half an hour.
This happened with my brand new tablet, so I returned it and the second and third replacements have been exactly the same. This happens using different chargers and in different locations (I have tried different sockets around my house and at work).
Has anyone else experienced this? I am about to return my third tablet for a refund as I don't want such an expensive device that I can't trust is going to charge.

Mine does this. I just chalked it up to new USB C charging standard and it calculating what to pump in to the battery before it begins.

Has yours ever not started charging eventually? That's what made me call Google support and the four people I have spoken to there all say it not charging immediately sounds like a fault.

It has always begun charging. Hell, maybe mines faulty too, but I never thought of that.

Mine does this, I wondered if it was a USB C thing too. when I plug it in the charging icon appears immediately but Ampere shows plugged in/discharging, the discharge rate starts low at approx 300mAh and over about 30 seconds rises (drops?) to, for example 1750mAh before flipping to displaying charge at 1750mAh. The final plugged in/discharge rate always matches the initial charge rate measured.
I usually charge using an Anker multi port charger and USB A to C cable. it behaves the same but with higher numbers with the Google supplied charger.
I am curious to know if USB C negotiating its best charge rate somehow fools Ampere?
I just bought a Pixel C and I am using it with a generic 5V /2A charger and a Dash usb C cable. It does the exact same thing that the OP described. I have to plug the USB end of the cable into the charger once or twice, before it starts charging. If I just plug the tablet in normally the lightning symbol appears and it does not start charging.
USC Type c takes 10 secs to negotiate. I would not use other chargers or cables. Stick with stock or known tested working ones. Refer to this spreadsheet
https://docs.google.com/spreadsheets/d/1vnpEXfo2HCGADdd9G2x9dMDWqENiY2kgBJUu29f_TX8/pubhtml
Remember ampere is not accurate and is only a best guesstimate. I recommend using current monitor in conjunction.
Becareful using generic cables and chargers risking frying your devices. If the cable is not made programmed correctly missing emarker or same for charger, USB Ttype C Power Delivery cannot not negotiate correctly. If it's missing altogether it may overcharge..
I've found the Pixel C to be a little picky with its chargers but the only really big disappointment was with the Pixel phone charger. That charger is supposed to support Power Delivery and can charge faster than the Pixel C charger can so I naturally plugged it into the tablet and it is useless! It connects and disconnects continuously so it never accomplishes any charging and the screen will not stay off. You'd think a charger and a device designed by the same company, advertising the same USB charging standard, sharing a marketing name, would work together!

You might have a defective Pixel charger or cable, it has been known to happen. That is why people have gotten replacements.
On that note consider that the Pixel comes with the same charger as the XL, but it doesn't charge at any faster rate than 15W with it's own charger..

Yes, I have heard that the Pixel-xs doesn't make use of the higher voltage (9v, I think?) charging option, but I was hoping the Pixel C would. It is known to work with other higher power chargers. Maybe I'll call up the old Google and see if my charger is bunk. Even if it is no faster it shouldn't cyclically fail to auto negotiate like it does.

The Pixel C is 5V/3A 9V/2.67 12V/2A. I use both the Xentris/verizon USB-C/QC ($9-40) and Targus 45W ($30-55) chargers, both charge my Pixel C at 24W 12V/2A. It's great.
I have just purchased the Belkin charger cable that is on the Google list. The tablet's behavior is still hit and miss on the 10V/2A chargers that I have. I am using the Samsung S2 charger (should be plenty good quality). I am not even looking for fast charging or anything, just consistent behavior. If I plug in the usb C end of the cable ampere starts to show a discharge rate of like -500 mA and it does not start charging. The built in battery indicator says USB Charger = not charging. This happens about 7 times out of ten. In the other 3 cases it starts charging when the USB C end is plugged into the tablet. If I look at Ampere and see that is does not charge for like a minute, then I unplug the USB 2.0 end of the cable from the charger, re-insert it and voila it starts drawing 2000 mA immediately. I have tried 3 different chargers so far and the behavior has always been the same.

The Pixel C uses USB Type C Power Delivery 5V/3A 9V/2.67A 12/2A. 24W max
Ampere app is rather useless and just for reference. (note I use it often) Try Current Monitor. Regardless both rather useless, since the Pixel C doesn't negotiate faster charger until after the screen turns off. So while you have the screen on looking at Ampere/Current Monitor, you're gonna get a fluctuating reading that doesn't make sense. I use a kill-a-watt to see the wattage being pulled.
I am able to get a solid consistent 15W charge out of the stock OEM charger. I can get anywhere from 15W (screen on) with my Xentris/verizon and Targus 45W chargers and 24W (screen off).
Also note USB-c is not consistent, it negotiates different levels and it always changing depending on several conditions, like battery level, temperature and if screen is on at the time.
I've attached some results using LG V10 OEM Charger, Samsung Fast Adaptive Charger and Asus Nexus 7 charger with USB A to C with 56k ohm pullup resistor connected to the Kill-A-Watt for reference.
Has anyone managed to get a pixel 2 xl to fast charge using a normal usb a-c cable.
I have tried plugging it into a 2.4a usb wall charger and a QC2.0 charger and I can't get the device to pull any more than 1.5a
My pixel 1 used to charge fine @ 2.something A and it would say charging rapidly on the screen when charging.
Anyone got any experiences?

Unlikely that you'll get fastcharge from a-c as the fast charge only comes from Power Delivery (this is not the same as Qualcom's Quick Charge which usually has a usb -a connection on the charger). The only chargers I've seen that implement it are usb c to usb c (no -a connections on the charger). If there are any Power Delivery chargers that have a usb -a connection at the charger, they are rare as all the ones I've seen are -c only.
That's annoying as I had no problem with my pixel 1
Annoying inconsistencies.

Yeah agreed, Pixel XL fast charged with many different cable types etc, this phone hardly charges fast charge, off my macbook old phone fast charged, PIxel 2XL nope, some battery packs I had before don't do it any more. And whats worse when not in rapid charge it is stupidly slow to charge
My ankor supposedly fast charges my phone, at least that's what my phone tells me (rapidly charging). It's one of those 5 port "iq"chargers

Interesting, I have bought one of these to check.
I see no reason why this device cannot charge at 2-2.4a using a usb a-c cable.

Ok, so I just looked at it again, and now it just says "charging"on the lock screen and I'm below 50%. Either it only works with the phone almost dead, or something changed in 8.1.

I have noticed that it only charges using a C - C cable. I have an Aukey USB C car charger and it charges rapidly on the USB C port on that charger, but not the USB A port on the same charger.
This charger is also a QC 3.0 charger, and nothing mentioned about Power Delivery: http://a.co/aG7adl6
My conclusion is that it HAS to be a type C charger for it to go anything above 1.5a.
Annoyingly it's worse specification that the device that it replaced.
So this is very frustrating. I built a new PC in March that has a type C port on the back. I bought a Choetech C to C cable for it and zip tied it to my speaker wires so it would stay on my desk for rapid charging. I had a nexus 6p then and it worked without a hitch, I was able to get up to 3amps according to the ampere app and it displayed "charging rapidly" on the screen. Now I'm doing some stuff on my computer and decided to plug in my pixel XL, and I'm getting "Charging slowly" and its not charging faster than 480mah. Windows is up to date and my Pixel XL is on 8.1. Just tried the factory USB cable to see if that was the problem, and same thing, still doesn't want to rapid charge my phone. I don't know where to start to figure this out. Is this some weird oreo setting? Is it something in windows? BTW the motherboard is a MSI B350 Tomahawk. Thanks
Most USB ports are 5V w/ X amp - these phones use a higher charging voltage for rapid charging, resulting in slower charging from previous rapid charging adapters or ports.

Yeah but this is a type C USB 3.1 port, and it has rapidly charged my Nexus 6p I had previously on more than one occasion just like plugging it into the wall. A type C port on a PC is capable of supplying 15 watts I believe.
I just put a type C charger on my power strip. So freaking annoyed about this. About to RMA my motherboard. No one has any answers for me. The port is literally useless as I can get USB 3.1 slow charging out of my regular type A ports. Am I the only guy in the world that used his PC with a type C port to charge his type C phone? Sure seems that way.
The same happened to me. I have PC with a mobo with USB-C 3.1. When I got my Pixel XL, a few months ago, I clearly saw quick charge when I used it... but now (I don't use a lot charging over my PC) I plugged it to my computer and no more... any ideas?! Maybe February or March update ruined?!

I'm pretty sure Google disabled it on purpose because of the overcharging bug affecting the XL when using type-c to type-c charging .

Well, if this matters I tried today to charge via usb-c 3.1 on my computer, and for a fraction of a second I just saw charging rapidly on my XL screen !!! Then it fall to slowly charge... Fckv Google!!!

The only way I ever get rapid charging is using the original cable/google usb-c + original charger
I have usb 3.1 on my computer and don't get rapid charging.
I mean, if your computer works with your 6p, then you know it's an issue with the pixel xl. it might be software, it might be hardware - when you use original cable/charger you get QC?

well this is not so true... I have a car charger from anker, with 2 usb + 1 usb-c port and I get quick charge from usb-c port!!! And I'm using a usb-c cable from anker too.
I have the MSI Tomahawk B350 as well. The type-c port doesn't seem to recognize my Pixel 2 XL nor charges it at all. It's a new PC build so going to have to contact MSI to see what's up with that.
Guess what guys, the fast charge that I lost a few months ago, now with the October update, I finally have Charge Rapidly when charging via USB-C on my windows PC !!!! Yeahhh!!!
I have a charging problem with my Pixel 2 XL.
It will not charge with any wall charger or car charger.
I have one of thoes portable battery banks, and it charges the phone just fine. It also charges when plugged into a computer.
Anyone have any idea why this is happening?

I have an issue where sometimes the stock charger (as well as a replacement) will very often only charge my phone when plugged in one way. All other chargers are fine.
Well I went in the settings, did a factory reset. Still had the problem.
Then I downloaded and flashed the factory image with data wipe and phone charges like it supposed to now.
I had a problem with this as well.. it will charge on anything that is low amp... It won't connect to computer to transfer anything but will charge slowly.. I had mine replaced and they said it was the charging port..

Warp charging doesn't go beyond 3.5Amps on ampere app causing slow charging rate shouldn't it give close to around 5.2Amps charging speed? Can anybody share their screenshot or is there a issue with my device

With Warp Charge there are several factors that come in to play. The charger itself, the USB Type-C Cable and your device.
Has Warp Charge ever worked on your device?
When the cable is connected do you see "Warp Charge" displayed on the screen?
Did the Ampere App ever show the maximum 5.9 amps or does it always show a maximum of 3.5 amps?
Are you using the original Warp Charge wall outlet adapter and original USB Type-C Cable?
If Warp Charge was working before, how long has it been since you last saw it work?
Have you modified the device at all?

Yes it was all working before I have earlier got 5.2 to 5.5 amps but from past couple of months it's been fixed at 3.5 amps now, and yes I have been using original warp charger provided and no haven't unlocked or rooted my device, could this be a problem with the device or any other fix for this?

Bought mine 2019-12 . few days ago (2020-03-30) warp charge stopped working, it still charged, but extremely slow like 40 percent an hour. When it was off i tried plugging in charger, but it started looping, it didn't boot to an animated picture with charging battery, but it still could boot into OS when power button was pressed. Did a factory reset, didn't help. Connecting to pc usb still recognizes it. Had a feeling it was a hardware error. Maybe fast charging module went bad.
Sent it for a warranty repair, got an answer that it will take more time because it was sent for an higher level service. I guess it's quite bad, it could be a motherboard fault.
I read on oneplus forums that quite a few people has a same issue.
Connect it to a pc, see if it is recognized. Mine stopped working & it was a bad USB Car port. It would still slow charge but no warp charge & no windows pc would recognize it connected
Hi! I have the same issue, only difference is that mine is sometimes charging at warp speed and most of the time at 3300 mAh "dash speed". Did you manage to see what the issue was?
