Hi guys so I bought a nexus 6p a month ago and been loving it. I almost have nothing to complain about except this issue.
After using it a few times I've realized that sometimes the battery goes down in less than 2 hours screen on time while sometimes it lasts for about 4 hours screen on time.
After monitoring the battery usage regularly I've noticed that the phone never goes to sleep after plugging in the charger until the phone is restarted every time. So in short I have to restart my phone every time after I charge my phone to prevent wakelock.
While this definitely isn't that serious of an issue its still really annoying and the nature of the issue is really weird because as long as I restart my phone after charging the wakelock never occurs. I've tried uninstalling all the apps, switching off Bluetooth and WiFi but still no luck. I doubt it's app related as it only happens when I plug in my phone to the charger. Does anyone have an idea what's going on and any solution to this?
Thanks in advance
Is this always using the provided wall charger or a 3rd party charger. I've had pretty strange behaviour when u used a cheap USB a-c cable with my car charger, had to buy a decent branded cable in the end.
My phone refused to charge off the wall charger after I used the cheap cable until I did a reboot. It might have caused wakelocks but I stopped using it pretty quickly.

So I started charging my phone earlier and it took forever, and the phone got very hot, but I didn't think more of it and unplugged it. Then it dropped under 15% and I decided to charge it again. It's been in the charger for 30 minutes and it's only gone from 9% to 10%...
Am I the only one with this problem? =S
Edit: It still gets very warm.
Turn it off and on?

I was sort of hoping it went without saying that I had done that.
I've also tried:
Charging it through my PC
Charging it through the wall charger
Both give the same result as listed in the first post. Also tried removing everything (battery, simcard, mem.card) and reinserting it.
Still it gets very warm and charges almost nothing! =S
Are you using a different USB cable or charger than the one provided?
I have tried several different USB > Micro cables and not all of them have worked properly.
My old BB wall charger works fine, as does my old Motorola one (both plug a USB cable into), but wife's iPhone one does not.
I really don't think that's the problem... I finally got it up to 100% with the wall charger, but when I restarted it after having reinserted the MicroSD, it had dropped 13%. In a few seconds, does not make any sense =S
Night time here now though, so gonna see how much it loses in just standby, if it's a lot I'll try reinstalling the update. But this seems to be an isolated issue?
I noticed that charging it with the wall charger is at least 3 times faster.
Also, you're right, the phone can get really hot while charging and at some point it even stops charging when it's too hot , it happens easier when charging using a computer since the charge takes more time, the only thing that helped in my case was to remove the battery cover and blow some air on the battery
The problem sin't that it charges SLOWER, it charges about the same for both, currently. The problem is that it hardly charges at all...
Also, it was at 100%, then dropped to 87% just with me turning it off, reinserting the memory card and turning it on again.
I went to bed at 2am last night, then it had 87% battery. When I woke up at 9am, it was dead.
your battery is faulty
email SE telling them your battery wont charge but that your friends/spare/new battery does charge when in your phone (to rule out the usb fault that some x10's had) and then they should send you one out.
As of this morning my TF nor the dock will charge from the charger. I suspect the charger itself is damaged somehow but I cannot find anything physically wrong with it from the outside.
EDIT: Weird, after the 20th time playing with it, taking it apart, reseating the USB cord, etc, it finally started charging again after hours of aggravation. Hopefully it stays that way....
I'm thinking the inner pins somehow lost contact with the interposer. I've also noticed that the adapter gets alarmingly warm when charging. As in it's hotter than the PSU I use for my Alienware m17x R2, which is almost hot enough to give a mild burn.
My charger gets pretty warm as well. I think because its charging the device at such a fast pace.
Takes twice as long to charge my phone than the transformer!

Yeah I'm just hoping this whole thing doesn't keep happening. Had the charger on the dock for a while before I realized it wasn't charging since there's no indicator other than the LED. I'm just glad I got the dern thinking working again. Figures it would get fixed not 5 minutes after I post here and send a ticket in to Asus.
I wonder if cutting a few vents on the charger or at least blowing some air with a fan might help. Perhaps there is a thermal protection shutdown circuit.
there are several threads about this here one;

i had the same problem, not had it since, something is definitively happening with the charger, changing sockets seemed to help
My charger actually died on me. It doesnt charge at all anymore with the included charger. I can still use the cable to charge off of USB, but that is sloooow. I bought an iPad charger (2 amp) and it charges a bit faster. At least I can still use my tablet until a replacement charger is available.
Just FYI I was told by Asus CS a replacement would not be available for awhile, and they wouldn't RMA the charger by itself.
Sounds like many of the charger problem is the contact between the country plug adapter and the charger itself. First thing I would do if it stopped charging is remove the country plug adapter , clean contacts and reinstall. Sometimes in the process of plugging in or removing the charger, you move contacts enough to either make or break the connection.
Loses charge significantly on standby
I left it on standby last night @ about 70pc. When i turn it on this AM, it is at 20pc Any workarounds?

Standby and off are very different states. In standby, it's STILL RUNNING. If you leave the WiFi on, it's still communicating over the network. Applications are still running in the background.
I did a test recently (right before I got my dock). I left the TF in 'standby' with WiFi on (turned off the sound) and went to sleep. About 9 hours later, the battery was down around 50%.
Next day I did the same, but I turned off WiFi. Battery ended up still being above 90%.
The workaround is turning it off. Disabling WiFi reduces battery consumption in standby, but it does not eliminate it.
And for the 'stopped charging from the AC adapter' issue, it seems that unplugging the adapter from the wall for a while seems to reset the charger.

I feel this is a shortcoming of honeycomb than asus. hopefully this gets fixed in a future update. Havent seen this behavior in any other mobile device.

Which part do you think is a problem with Honeycomb instead of Asus?
The dock issues or the power supply not charging? How can the OS be responsible for either? (save for driver issues with the keyboard, which Asus fixed with an update)
I actually had this happen to me, but reassembling the charger didn't fix it for me. I ended up restoring to fix it. Haven't had any issues since.
I had the same problem. Did as stated above... Left charger unplugged for 20-25 minutes, then gave it a try and now it's back to charging... All good.
Information of PSU model with known fault here:

Possibly a related issue? My Transformer is now not charging although I believe either my cable is faulty or the connector to the tablet itself. I don't have my official Asus charger with me today so I plugged it into another USB power charger and I get nothing. When I plug the cable into my computer the Transformer does show up as a device in Windows however there is still no charging.
I am having a weird problem every now and then. Most of the time when I charge my phone it juices up all the way fo full, no problem. But every once or twice a month it charges to about 70%, then just stops (see attached screenshots). If I look at the lockscreen I can see the charging notification flickering on and off. It won't charge to 100 unless I unplug and replug, then it seems to fix the problem.
I'm on stock rom 4.2.2, faux kernal v11.
Has anyone else had this problem? Any help would be appreciated.
try turning phone off, then charge it?
same issue?
Plug/Unplug the cable and the charger several times, does the trick for me
Yea, I can get the phone to charge again by unplugging and plugging back in the cable, it just kind of stinks to wake up and find out that my phone didn't fully charge overnight.
It's not a big deal, I was just hoping someone found a solution to stop it from happening.
The solution I found is using a different charger

I think I'll have to try this, I'm currently using the charger that came with the phone, but maybe I'll try one of my older chargers and see if that fixes the problem.

Used to happen every so often to me with the stock charger too so I bought a different one and it just happened to me again last night on the new one after a couple weeks of use.
i have this issue too, it will charge fine for a while but then ill wake up in the morning to see it rapidly switching from AC to Not charging over and over again. i dont know why but i dont want it to damage the phone
Same crap here
Since it happened the last time I've switched to using my old Sony charger and cable. So far so good, hasn't happened again...yet.
Hello, it has been happening to me for last 2 days that when I put the phone on charger, the battery sometimes charges at an extremely slow rate (14% to 23% in 1.5 hrs), and sometimes it even discharges while the charger is connected. I am attaching the battery screen here.
You can see that first it goes down from 100 during morning to evening. This is normal behavior owing to my usage. Then I charged it and up goes the curve with a high angle because I use a good charger. This is also fine. Then I disconnect and heavily use the phone again and then put the phone on charger overnight. This is where the problem starts!
Now you see, first of all the battery starts going up then it suddenly starts dropping while still on charger. I woke up to find 23% battery after charging overnight. I noticed in the screenshot that my phone was constantly waking up all night long, may be this could have been the problem. So I connected it to charger again to see the battery level rising in front of my eyes. But again, after 3 hours I found that my battery is 51% and the curve has started to fall down again, and this time there were not enough wakeups.wakelocks.
I am using a powerful charger. It is made in china but it charges all the phones in my home perfectly. I also tried on another charger (also probably china) with the same results on my phone only.
I am using the stock rom, unrooted (can't root version 182.*.*.*)
Do you have thinks running in the background while you charge? Mines charges a lot faster if I turn off internet, kill background apps.
Also is it overheating while chsrgeing? You get a better charge if the phone stays cool
And third your phone might think the charger is a computer. I say this because mines charges really sloe when I connect it to a computer, like 12% per hour. Try a third charger, diffrent brand and wattage compared to the ones yoive tried. it might help.
yes there are background apps but there hasn't been a change which triggered this. the background have worked fine before.
no overheating issue. in fact, this device always feels cooler.
I've always used this charger, my whole family uses it without any issue but now the problem just started happening to me. and even with me the problem is not constant. I just charged up to 50% without any problem. there is one thing left to try. that is, I should try to restart in safe mode and try charging in that mode. if that works fine then it's definitely an app, otherwise the issue may be bigger.
I had my axon 7 for over a year now, but just started experiencing a charging issue. When the device is on and I plug in to charge, it simply doesn't receive a current to charge. But when I shut off the device and plug it in, it charges and then when I turn on the phone with the cable still plugged in, it continues charging. What gives? I'm assuming it's a 3rd party application gone rouge because I switched chargers and none of them seem to work...how can I get to boot into safe mode to test it when the phone is on...and any ideas of which apps or processes can be the cause of this problem?
That issue it's driving me nuts as well that just started to happen last week I guess it's time to change battery or something I'm not planning to upgrade my device still on immaculate form and zero problems until last week
