Slower charging since April update. - Nexus 6P Q&A, Help & Troubleshooting

https://imgur.com/LEgJCkc max current is lower, hasn't hit 3000ma since the update. Anyone else experiencing this? Using stock charger with anker type c cable that previously charged at full speed.

I've been having this issue since the March stability update. Using the stock charger with the stock C-to-C cable, I never see "Charging Rapidly" on the display anymore, and Ampere reports that my device is only seeing 1500mA. Some people have had success getting their devices to charge rapidly again by rebooting, but that doesn't help in my case.
I have had success getting my device to charge rapidly by swapping out my USB C cable to a 3rd party "Benson Approved" cable. If I swap cables, my phone will charge correctly until the 3rd party cable is unplugged. Plugging back in the same cable will result in slow charging once again. If I then swap back to my stock USB C cable, my phone will charge rapidly, but only until the cable is unplugged, then back to the slow charge.
I've been hunting for info since the March update and have seen a few posts here and there with the only suggestions being to reboot the device, which fixes the issue for some. I wish we could confirm that this is more widespread than just a few devices and get Google to issue a patch.

Have you tried to sideload the April update to see if that helps. I still get "charging rapidly" on the lock screen, maybe there's an error in the reporting of the charging rate. My charging speed is still similar to before the update.

Unfortunately, that's how I installed both the March and April updates. I'm to the point where I'm going to either update to the N preview when the next release hits to see if the issue is resolved there, or I'm going to factory reset and re-flash the entire OS back to the release prior to the March update.

I also have this problem.

I'm getting the same issue. Using the AC charger and original USB-C cable that came with the phone (which I know allows Charging Rapidly) won't quick charge my 6P after the April update. Even directly hooked into the wall. No idea why it's doing this...
EDIT: Nevermind, I restarted the phone and it's all good now.

same issue with "charging rapidly" no longer showing up. doesn't matter which charger and cable combo I use. also persists after I reboot and after clearing cache.
Not sure if related, but my meenova is no longer recognized as well.

[Q] Nexus 7 Charging Issues

Hello;
So far I am really enjoying the Nexus 7, except for charging issues. I can only charge it via usb from my Chromebook, when I plug it into the Asus charger or my Nexus S charger, nothing happens; my Nexus S will charge using either charger. I have tried doing a factory reset several times and the problem still exists. Also, I haven'f flashed it and currently I only have Google Apps loaded on it, the latest official Android update (4.1.2) has been done.
Suggestions?
Thanks
Sheldon
If I use the charger and cable that came with the N7, everything works as it should. I tried an alternate charger/cable one time and It didn't show it was charging and didn't show the charge % increasing. But I left it plugged in a couple of hours and when I unplugged it, it updated the battery % and it had gained charge. I think it can be a reporting issue as opposed to a failure to charge. There is something different about the N7 charger or cable that makes other charger/cable combinations report differently.

[Q] Overnight: Charging to 100%, then discharging while still connected?

Hi there,
got a strange problem.
I plug in my N4 in the evening, it is loading up to 100% and there it begins to DISCHARGE (or in other words, stops to hold the battery at 100%) although still connected to the charger. In the morning I unplug the phone and have just around 70% left ... see attached screenshot.
Using stock charger and cable that came with the phone.
I hope this is not intended by Google? Running Android 4.2.1 Stock.
is this the only time it happened?
It is probably because of the charger. They definitely didn't include the best charger out there try another charger, you'll see improvements.

Thanks! Used my equipment (powered USB hub with another micro USB cable) from old phone until yesterday, and read about charging problems when NOT using the charger and cable that came with the N4. To see if that is maybe the problem I therefore unpacked the "stock" cable and charger - but it didn't solve the problem.
The most strange thing is, that it charges perfectly up to 100%! I would expect then that it stops charging to avoid overloading, but that holds the charge level at 100% until unplugged. I think this logic is not within the charger, but controlled by the phone itself (Software / Hardware Unit)?

Have the N4 about 1 week now and I realized this happening at least 4 times now. I'm usually plugging it in every evening and unplug it in the morning.
Its intended as a safety measure so it doesn't over charge when its 100 percent.... It's always been that way

Hmmm ... never experienced this 15 years mobile phones (at least 4 of them using Android and tons of different ROMs ...). What would be the purpose to plug in your phone in at 22pm, stop charging at 1am and begin the fresh day at 7am with again 30% loss of capacity? I would need to carry my charger stuff all day with me ...
As I said, I fully understand that it stops charging at 100% to avoid overloading - and also see the sense in this here -, but usually it should HOLD it at 99-100% until you unplug and not lose capacity while still connected to the charger.
Cheers
did you plug it into a USB hub that was plugged into a computer? that might be your problem. My N4 has issues charging from USB ports... it never holds charge properly.
This happened to me previously, ended up swapping my charger back to my Samsung OEM one and havent had the problem again.
Another time that this could happen is if you're charging via your USB port on your computer and you shutdown your computer which it will still show the charging icon but the status says not charging which could be changed by replugging the phone and/or having BIOS settings that enable usb power draw etc...
Just found this one ... maybe I'm not explaining my case very well, but it seems I am not alone ...

Yesterday I used the wall plug. All the years before I used a SEPARATELY POWERED usb hub. Even if the PC is shut, the hub provides power to the ports. Anyway, it doesn't matter - Charging is working perfectly on wall plug, usb hub, stock cable, non-stock cable ... before reaching 100% and phone disscharges. Picture in 1st post illustrates the disscharge while still "charging" (last bar at the bottom)
it's def. not normal. mine doesn't discharge, it can stay plugged in all night and it'll say 'CHARGED'

Exactly what I would expect! Now that I found the others on code.google.com having the same issue I think there was a batch of devices having it and that I might need to RMA ...
Well the reason why I was mentioning the charger (unless you've tested another one) is because I was using the original LG oem charger and for a while it would give inaccurate readings on multiple occasions. Example being I woke up (used wall charger) and it said 70-80% and the charge icon was still there but on the status it said 'not charging'. Another time was when it said 96%, unplugged and replugged and it charged to 100%. Then I use the phone for a couple of seconds and it drops down percentage again 96%~ and when/if charged it will say 100% again (giving a false reading).
I was thinking it was the cord because I used my bro's LG charger and it charged the phone 96, 97, 98, 99, 100 and not 96 -> 100% therefore the cord may have been the problem. Went back to my Samsung OEM charger and it has been fine since then and never had any discharging.
Are you using stock kernel?

I'm on 4.2.1 stock yes.
Thing is, that I'm not plugging it out! While being connected it suddenly starts to disscharge - Why the heck would you disscharge when you have a power source connected?! The "event" invoking the disscharge to me is the reach of 100%. Maybe this is a misbehavior of the overloading protection, to stop charging (as intended), but not restarting to charge at lets say 99% or 98% to get back to 100%. This would mean that when I'm using navigation in my car I would need to reconnectfrom time to time to trigger the charging again.

Yeah I know what you mean but its odd that I had this problem as well but disappeared when I swapped.
As for my USB/PC, that charges when the computer is on and off but when I turn it off, I would have to replug the phone to get it started again as it will have the same "charging icon" w/o it actually charging. My guess is that if the power source loses its power, even if its temporary it will stop charging. But when I using my Skyrocket a few months back I never had to replug the phone onto my computer to get it charging again but I do know that the computer will temporarily cut off power when you shutdown and bring it back to charge plugged devices. (didnt change any power states in BIOS).
So most likely it is something with the phone but it could also be a setting or some software error triggering a fail-safe or something.

I see definitely some issues in the charging logic in both of our cases here. You shouldn't have to replug your phone if you send your PC to sleep, as long as it still outputs the USB power. Since I would not expect the decision to charge or not to charge in the wall plug or in the USB hubs, I can only hope it is not a hardware problem of the charging electonic, but a software problem which could be patched. Also wouldn't I wonder if this has to do with the wireless charging option of the phone ...
come to think of it i had the same problem. charging from the PC when off via USB it would do the same thing as OP. charging through the wall works fine.
Well just found out I am maybe reposting the issue as I didn't find this initially ... similar (or same?) problem described here: http://forum.xda-developers.com/showthread.php?t=2031246

Charging Problem

I am having trouble charging my tablet. When the tablet is on, I am unable to charge with either the POGO or USB cable. I have also tried other wall chargers for cell phones. I was not using any roms, but had tried out the ktmantra kernel. I have since wiped my tablet using a factory 4.2.2 image from google and am still having the charging problem.
The only way I am able to charge is by charging with the tablet off. It also takes ages to charge (12+hours). Any ideas on what could be causing this? When I plug the POGO cable in, it says it is charging, but the battery percentage continues to drop.

I've readed some comment on another forum from an user that has the same proble, but for him it takes about 10h. Not sure what's wrong.
Are you not able to charge at all or just very slowly? I just noticed that my Nexus is charging very slowly with the Pogo cable I purchased. I may try going back to the usb cable to verify that the problem is with the cable and not with the tablet.
I was getting very slow charge rates with my usb charger. Around 12 hour charge times even when completely powered off. Anyway, my problem was with using a USB extension cable. Since I started plugging it directly into the wall I've been seeing charge times in the 5-6 hour range. My iPad never had an issue with it, but whatever! You might also try a different wall outlet.

I cant seem to solve this problem. I have tried using pogo and usb cables with two different chargers. I have also tried using different wall mounted phone chargers. I am not able to get any positive charge while the tablet is on. Using the battery monitor widget, I used to see a +1800 charge with the pogo, and a bit less with the usb cable. Now, the highest I get is -500.
I am only able to charge when the tablet is off, although very slowly. I had it charging all night, and it is now at 60%
When I plug the pogo cable in, the tablet will say it is charging, but it really isnt doing anything.
Any ideas?

Recalibrate battery? It's probably not going to work though. RMA the tablet as a last resort.

How can I recalibrate the battery?
Im in Europe until June, so Im assuming it wont be easy to RMA.
There is also a strange thing going on with the usb cable. My computer is unable to detect it as a storage device. When I plug the charger in, it will not show up as charging when the tablet is on. But, I am able to access the tablet via fastboot.
Where is that oficial pogo charger from samsgoogle? 4 month and counting... 2 Biggest companies în the world are unable to produce a simple cable... Hillarious

The N10 charger is a 2 amp charger and most phone chargers are 1 amp chargers. The N10 will charge slowly with a 1 amp charger if it is powered off, however it needs 2 amps to run the N10 and charge at the same time. Also I have found that not all USB cables are created equal, you may want to try another usb cable. I do not know anything about the pogo chargers. Hope this helps.

Nexus 7 wasn't charging while turned on.

Hey guys, I'm just looking for some insight here, I went to go plug my tablet in today and low and behold it wouldn't charge. I tried restarting it to no help, and did other troubleshooting options to make sure the power outlet and the original cord and adapter for the N7 were working properly. But then I noticed something weird, I put it into tarp recovery, plugged in the charger, rebooted recovery, and now its charging fine. It shows it charging in recovery AND when I boot into android all seems OK now, my question is what could have caused this and should I be concerned that this could start happening more often.

I don't know if this has anything to do with your situation, but I once used a 3rd party charger and 3rd party cable and it didn't show the charging graphic. The battery meter didn't change either, so after a coupld of hours, I unplugged it. It obviously had been charging since the battery indicator jumped up to a nearly full charge even though there were no indications it was charging. I always try to use the oem charger and cable even though I have found some chargers and cables that work as the stock one.

Wireless Charging issue after latest security update

Has there been anyone else experiencing an issue with the wireless charger since the last security update.
Now instead of charging the phone like it did before, it just holds it at the level it is at.
Anyone know why this is happening now, and how to fix so it charges?
Thanks.
You have gone to the menu item fast wireless charging?

Any Updates?
Hey, do the downgrade to PE1 with full wip, and put 100%, your working fast charging. Good luck. To me it helped.
I'm on PH7 and wireless charging works fine for me.
Wireless charging has never been an issue for me with any update. Might be purely coincidental, but you can also try a factory reset incase a setting or system file got skewed.
Have you checked the charger with another phone, or another charger with your Edge. It's possible the charger coincidentally failed at the same time.
My USB fast charging doesn't work. Wireless charging works faster than USB with different fast chargers. I have tried 6 of them and still not getting fast USB charging anymore. It is checked to fast charge also. All happened after the PJ3 update.,
Have you tried different cables, too? If the original charger and cable don't fast charge your phone, it's probably time for warranty service.
