I am having battery issues with my Nexus 6p. I thought it was the battery issues with shutting off, like many others have mentioned. I did a factory reset to try and address this, but I noticed in the battery setting, it says the phone has not fully charged in over 27 days. The battery display shows 100%, so I am at a loss on what is happening and how to fix it. I am running the current Nitrogen rom, but this was apparently an issue before switching to Nitrogen 2 weeks ago. Any suggestions?

I've never had to do this but it sounds like your battery needs to be calibrated which is misleading because Android is actually what you are calibrating. The above thread should be helpful.

I'm finding that sometimes when I plug in the tablet to charge even if they battery is almost full, as soon as I plug it in it will think the battery is at 0% and start shutting down.
When I power it on and look at the battery stats it shows that the battery went to zero and then goes back up to were it was before the shutdown.
Also another issue is that the battery status will say its not charging even though it's not plugged in and the level never goes down even after a reboot. I find to fix it I need to go into a custom recovery and reset the battery stats for it to return to normal for a few hours.
I'm running on the stock image.
Its annoying, but I'm hoping that the next update will fix this.
Can't say I've ever experienced such an issue, on any device. If your looking for a fix, perhaps reflashing the factory image completely might help (I don't understand the battery stats file too much, but I would think a reflash would probably replace that file, and fix the problem).

I thought I was the only one with these problems. Never had these issues on my Galaxy Nexus. Now on the N10 I have the first problem you mentioned + battery % not moving until I reboot the unit (Random). Very annoying...I called Google Play support and after doing some test told me that they'll send my a new unit.
Note: I've flashed the Google image and I still had the issue (seems less frequent)...Sometimes I can have the % correctly refreshed and sometimes it stops after a few minutes.
I've attached screenshots of the problems...(1st image) Long straight lines were when I was actually using the device!! Cut in graph = reboot
Second image: both problems, check out the spike a 0%!! when plugging usb cable

I have the same issue and my replacement is on it's way.
So I called support and I'm getting a replacement device.
I've been searching everywhere, thanks to this thread now I know I'm not the only one having these exact same issues. Looks like I'll be making a call to Google Support
Probably a software issue to be addressed in a later update.
Are these issues still present on the replacement devices?

So far not happened on my replacement device. Went from 70% to almost 10%. Still testing. Also wakeup time is normal. I think it was hardware related.
EDIT: on my 3rd day and this new device always correctly reports battery life. Definitely hardware.

I'm having the exact same issue with battery % not updating at random times and then sometimes the n10 claims 0% battery after recharging overnight and promptly turns itself off. Did the replacement unit fix this for you?

I got my replacement unit 4 days ago and the problem is definitely gone! On my first device it also happened since day one.
My Nexus 10 just started doing this after a reboot last night, I guess I'll have to ring support and get a replacement.
I'm running a custom kernel, recovery and unlocked bootloader. Do I have to flash back to complete stock before I send it in?
Cheers guys
I'm not sure if I have this issue, but my N10 is definitely acting strange.. I put it in my bag this morning on 42% charge and when I took it out in the afternoon it was dead (I thought I might have hit it to something and damaged it), but when I plugged it in it started to charge after a few minutes from 0%. Then it rebooted after like 5 minutes without me touching it and it's charging for now. The battery stats don't show a drop to 0%, the graph ends at 42..
I've had this device for around 3 months now and never encountered this issue before, so I'm not sure if it's really a hardware issue, but I'd be quite disappointed if I had to get a replacement as this one is a really good one in terms of the other common issues (bleed, throttling, creak).

I just started getting it since updating to 6.0.1 PN. I switched to AK Synapse and it drastically reduced it, but it is still there. Only info I can find is much older phones. I am using an LED manager...wonder if that could be it. May freeze it this week and see.

I believe that wakelock is from charging. I don't know why but the device doesn't seem to register as deep sleep with better battery stats when fully charged and then idle but still plugged in. Likely an issue with the program and not the phone.
However if you want to test this simply charge your phone over night. Once it hits 100% it will stop charging at some point and go into sleep mode. The device is still plugged in but won't charge anymore. Device will use power, mine is usually around 95 or 93% when I fire it up and use a little juice in the morning. During this time the device uses battery quickly until it drops to 89% or so then normal discharge rate. This is normal of most android devices I've had and most everyone here is aware of this:
http://phandroid.com/2010/12/25/you...is-lying-to-you-and-its-not-such-a-bad-thing/
Getting back to the wakelock issue, f you check better battery stats this wakelock shows up under the above condition. You'll notice the time on this wakelock is usually the sum of the device on but screen off time and your screen on usage or pretty close to it.
Now charge your device to full while waiting for it (as in not going to leave it for 4+ hours on the charger after it is full). Once it stops charging at 100% pull the device. Use as normally.
Now the device is fully charged. Really this time and not just the UI telling you it's full. When you use it throughout your day and then check better battery stats you'll notice the wakelock is no longer there or nearly so depending on how fast you got the device off the charger after it was full.
End result is this seems like a reporting issue with better battery stats or the device not fully going into deep sleep while being plugged in. I would tend to lean on a reporting issue as discharge time seems about normal at 1% or so per hour while idle and that tends to hold true to my regular doze discharge.
TLDR:
This seems more like a reporting issue than actual wakelock. Any significant battery drain when fully charged can be explained by the link above and testing as I have explained in the post.

The only thing is this wakelock doesn't start until after I unplug it and leave for work. It grows during the day..so is it faulty reporting? Something is using my phone when idle for about 2 hours a day with screen and sync off at 384 Mhz and that wakelock usually shows at about an hour and 10 minutes or so. I have also done as you said and after it dropped to 97% charged it back up and pulled it off immediately..same wakelock and similar time. Also this wakelock was not there with 6.0.0. So Google changed something with 6.0.1 that brought this to life for me. Also interestingly, this wakelock was at about 4-6 hours with stock kernel. I changed to AK kernel and that is what made it drop to about an hour and doubled my standby time.
OK, I froze Light Manager with TB and this wakelock went away. This was the only new thing I added to 6.0.1 to get the battery fully charged light to not change until 100%. Stock changes it at 90% for some stupid reason. So if anyone is using an LED manager, try removing it for a day and see if that makes this wakelock go away.
so here is the source. Are you guys all using the stock charger that came with the device? Only reason I ask is because I didn't start seeing this until I started using a samsung charger with a micro to c adapter.... I think
Reported at 93% it's my highest wakelock. Stock charger and no LED manager installed. Other causes or fixes?
I too have this at the top of my wakelocks. Did anyone else find a solution? I don't have any led managers

My new handset is exhibiting marked battery drain over night.
Last night it was from 30%, the night before 20%. In the morning it was dead.
The handset was off both times.
A battery fault?
Thanks
Agree with you, hardware issue, RMA

Did you try a reset?
I have now reset. I'm going to monitor over the next few days.
Try other rom. I have issues like yours (last 30/20 drops faster then rest of percentages), so I gave it back to service. But the told me that battery capacity is perfectly ok, so I think that its more like calibration issue, since when I lock my screen it drops 1-2% of the battery for no reason. I have not tried yet LinageOS, and that % issue is with me since B06 (i updated to B08, B10, now I'm on Nougat and nothing is changing, even after cache clearing and resetting)

I'm not sure how much effect a rom will have while a handset is off. I don't want to root a week old phone.
As it lost 40%, while off overnight, the retailer has agreed to change it.
Thanks, all
Hi!
I've been running Lineage OS for about two weeks on Zuk Z1 and I'm experiencing strange battery behavior. I get around almost normal hours of screen-on-time but in that time battery acts strange - suddenly dropping to 0% and sometimes working on 1% for hours.
Whenever battery drops to 0% phone gets switched off and when restarted it shows a different figure. My battery usage graph is equally strange. I have used battery calibration app but it was useless.
Can someone please help? Does anyone else have the same problem.

Your behavior isn't uncommon since few users experienced that. It's not a LineageOS problem. More likely your battery isn't good anymore. If you have warranty go claim it.

The thing is the phone worked absolutely fine before flashing ROM and moreover the battery life is good but it powers off automatically showing 0% then when restarted it shows the original percentage again.

Please read my linked thread.
Hi.
Yesterday I was using my Nubia z17s as always and before going to bed I decided to charge it, since battery was at around 20%.
When I connected the charger, the screen went off and it didn't wake up, no matter what I did, although I could feel the fingerprint scanner vibration when I used any of the registered fingers. So I decided to hard reboot the phone by keeping the power button pressed.
To my surprise, when the phone booted again, the battery percentage showed 3%. I left it charging overnight and now it's working but the battery percentage is stuck on 3%. I'm pretty sure it's more than that, since I've been using the phone for more than 6 hours and the battery percentage hasn't dropped a bit, and the phone is working (I've made an received a few calls).
A guy at work suggested letting the battery drain completely until the point the phone shuts itself down, and then charging the phone up to 100% while off, so the battery is calibrated and the percentage is fixed. But I've always heard that it's not a good idea to let a battery drain so much. Another problem is that I fear not being able to charge the phone again once the battery gets below 3%.
Any ideas? The phone is running latest Mokee 9 Premium.
Thanks in advance.

I had already tried that. But deleting that file just resets the battery usage statistics. It has nothing to do with the battery percentage
It seems to me that you will have to make a full data backup and perform a factory reset.
ps and which firmware in use?
Hi, I forgot replying.
I finally got the phone up and running again, and the issue seemed to be firmware related.
I was running the phone on Android Pie based Mokee ROM. I finally let the phone discharge until it shut down and charged it while off. Battery got up to 100% and the phone seemed to work fine. But, a few weeks later, something similar happened again, so I reverted to the stock firmware (still stuck at Android 7.1.1) and the battery issues went away.
I recently tested the Android 10 based Mokee and found that it reports battery level very differently than the stock firmware. Before flashing TWRP and the Mokee ROM, the phone was showing 88% battery left. Just after booting Mokee, the phone had apperently dropped to 78% and I also felt quite a huge battery drain. And it had only taken me around 5 minutes to install the recovery and firmware. So I guess the Mokee firmware doesn't handle the battery very well on Nubia z17s. It's a pity, since all the rest works very well, and I quite liked the Android 10 experience. On the other side, I was unable to make Magisk work under Android 10, and Google Pay is a must for me now, so I once again went back to stock firmware.
