Problem screen turn on during charge over night

Very bad bug, when i go bed and i leave my p6800 in charging i dont power off it,so when the tablet is fully charged the screen turn on and remains on until i wake up and turn off it manually with the standby button. So the screen remains on for about 4 hours per night! How can i do for automatically power of the screen when the tablet give tje allert that the battery is full recharged?

Did you try the screen timeout under settings>screen? As far as I can tell, it applies even when the device is plugged into a power source. I have similar practice as you but in the morning, my device would be charged and the screen off.

Yes, i have put the timeout to 15 seconds, but when the battery is full charged,my tablet rings and power on the display with the message that the battery is charged, i have wait 20 minutes, but the screen remains on. The only way to power off it, is by pressing the standby button wery boring, i am constricted to recharge my tablet from power off status ,in order to avoid this issue this is bad becouse i reiceive emergency calls during the night

Battery Usage Screen ???

Sorry if this is a stupid question I just need some clarification.
The battery usage screen shows how long you have been running on battery days, hours, minutes, seconds etc should this information be retained even after you power off, say you run it for 30 minutes on battery and power off when you turn it on again should it still show 30 minutes on battery and add on the new minutes or should it start from scratch again (0 seconds) ?

mine has been really inconsistent on my nexus. sometimes it'll be ahead a few hours but almost never does it exactly match up with the actual time. plus, it never updates if I press the refresh button. the only way to get it to refresh it to completely close the settings app and open it again. But yeah' a reboot tends to reset the counter.

So if its working correctly power off should reset the time counter because I'm sure this wasn't happening to mine at first hence the confusion plus the guide doesn't exactly read that way ?

That seems good

The battery usage stats carry on from where they left off from when the device was last powered down. They are only reset when it has been charged to 100% and unplugged.

Well that's what I thought it should do so I guess I'm unlucky then
The first one I had behaved that way for two weeks then started resetting back to 0 seconds after power off so I sent it back for another which I got today this also worked correctly until I charged it for the first time now that's also resetting back to 0 seconds after power off.
Not done anything to this one except install two apps, I sent the other one back because even a factory reset didn't solve the problem that was also on stock not unlocked or rooted.

[Q] Battery Stat/Graph Reset?

Yesterday I returned my N7 device because it won't turn on despite having around 80% on the battery the night before. I woke up in the morning to find that it won't boot anymore. I tried all methods like holding the sleep and volume down button for 30+ seconds, plugging it to the wall, and connecting to my laptop. I went back to the store to have it looked at, and since it has only been 10 days since I purchased it, they agreed to replace it with an available unit in their stock.
Now, with my new device, everything is well except that the battery gives inaccurate reading on the up time. The battery status/graph shows how long your device has been on battery, but fails to reset after charging. Suppose I have been using it for 22 hours, if you go to the battery details, it will show 22 hours of use, however, I believe that if you charge it, it will be set back to zero. In this case though, it continues from where it left off. Same with the screen time, it should be reset back to 0 after prolonged period of idle time, however, it continues from previous use.
Is there any way to fix this so I may get an accurate data on my battery activity? Thank you.

One way is to download an app called ROM toolbox and then go to ROM management>Management tab>Wipe options>Wipe battery stats.
I'm not sure if it requires root.

Thank you. I'm sure to try this out. Do you have any idea why it's acting up?

Well I can't really say since I haven't faced such a bug till now. But I think doing a hard reset fixes the issue because it's software related.(if the first method didn't work)

It depends on your charging behavior. If you unplug it at 85%, for instance, then it should not be reset. Same with screen time.

Note 4 drops from 50% battery to 0% instantly. Anyone else had this problem?

Hi there, I currently have a Samsung Note 4 running CM12.1 and in the past two days the phone has randomly "crashed" late afternoon/night (5.30pm today and 8.40pm last night). My phone performs fine throughout the day and then I'll notice that the screen doesn't wake up if I press the home button like normal. If I then power the phone on it boots up and instantly powers off after booting since it has "0%" battery. Both times the phone had plenty of charge in it, around 30-50%. Has anyone else encountered this before?
I have some screenshots but I am unable to post the Imgur links in my post because of my post count. Any other way I can post them?
Specs:
SM-N910F
CM 12.1-20151022-NIGHTLY-trltexx
Android 5.1.1
I can provide more specs if you wish.

Buy another battery, if another battery is OK then your old battery is broken

I had a similar issue where it would, after a clean software reset, shut down unexpectedly at 20% or so - then subsequently at 40%, 60%, and further 20 percent increments when I'd let it shut down of it's own accord. RMA'd it under warranty, pretty pleased with the service I got. No software fix for it.

Recalibrate your battery. I had this issue, too, after flashing another ROM. My Note 4 would shut down and die at ~50%.
1. Download Battery Calibration from Google Play
2. Fully charge your phone. By "fully" I mean not only to 100% (which, in your case, will be something like 50% effective charge), but until your LED has turned green. For good measure, just turn your phone off and let it charge overnight.
3. Run Battery Calibration, and tap the big button that says "Battery Calibration"
4. That's it.
You should do this every time you flash a new ROM, because there's always a chance your battery gets miscalibrated during the process.

Thank you very much for your help everyone, I'll try the Battery Calibration and let you know if it fixes it!
