Hi, just curious but is it a doze/marshmallow thing where the phone's power usage details shows "awake" (while screen off) when charging? I checked all the settings/dev options but doesn't see anything that sticks out.

The sleep option in the power menu, is it any different than taping the power button to to turn of the screen? (or letting the screen time out)
Sleep mode on a computer is a true low power state, does Android support this? I know that when the screen is off on my N1 that the OS is still running, because it has to for proper function as a phone. Now the Gtab does not need to keep running when you shut off the screen, so a true sleep mode would be great.
I have selected the sleep mode before, and to me it did not seem to take any long to "wake up" when I tapped the power button.
I think that if it is a true sleep mode, then it would be nice if we had options like a standard computer. Set the screen time out and then a separate time to enter sleep mode automatically when there is no user activity. Have it function like that when you tap the power button as well, auto sleep mode after 5 minutes or so.
It's the same as tapping the power button. Try to charge the battery full, and put it to sleep mode overnight. Do the same thing for tapping the power button. I've done this and next morning the battery is still at 100 percent full.
The battery indicator is slow to refresh upon waking back up I noticed, I guess experimenting could show if there is any real difference. Still , I would like to know from a deeper perspective, If the source is ever released someone with more knowledge than me could examine the code.
I too was wondering about the affect of sleep vs auto timeout on battery life, so I put my TnT Lite 2.0.0 to test:
(1) with sleep: after 12 hours the battery meter drops by 17% (I actually did this twice and got basically the same result)
(2) with auto-time out: after 8 hours the battery meter drops by 12%
So it seems that sleep and auto-timeout have the same affect on battery.
I am surprised to hear in post #2 that there was no change in battery life; after all, the CPU still runs, albeit at a lower clock. I do notice that when the unit comes back on -- from sleep or auto-timeout -- it takes a few seconds before the battery meter updates itself. Maybe that's the reason why in post #2 it looks as if there's not change at all?
In any case, I can live with dropping 17% over 12 hours, esp since wifi reconnects within seconds. The more I use the g-tab the more I'm amazed how well-built it is as a piece of hardware, and how much it was weight down by the stock TnT... Thanks to roebeet/rothnic/bekriebel et al for making this useable (and fun!).
I do not think the CPU runs on a lower clock when the screen is off, that is why SetCPU has the option have a profile to lower the clock with the screen off.
If we can get SetCPU to work correctly, this thing would hardly use any battery if set to minimum clock speeds.
Stock S6 (T-Mobile, 64GB, White). I have two different QI chargers (one is the TYLT Vu Wireless Charger (Qi) and the other is a CHOE stadium). The phone charges fine with both chargers, but the screen keeps turning on while charging and I can't seem to find a setting to disable this.
As soon as I put it on the charger, the screen turns on, so I hit the power button. Usually it turns back on within 5 seconds, so I hit the power button again. It will then stay off for a while, but if I wake up in the middle of the night the screen is back on again. Any ideas what is causing this?
I have noticed that the screen tends to turn on when I get a notification or when the "searching for GPS" pops up on the lock screen, but in both cases the display will dim but it will not turn all the way off.
Edit - forgot to mention that I get the same results regardless of whether or not the phone is in a case.
I got the same thing with portable battery packs... very annoying.
Also mine keeps getting off and on all the time.
Strange - my screen turns off fine if it's plugged charging via USB. It's only wireless charging that has issues on mine.
The screen always wakes up when it starts or stops charging. Do you have the developer option turned on to leave the scree on when charging? If so, when it wakes up at the end of charging, it will never turn back off. If you don't have this option enabled, then I don't have a good reason.
Thank you thank you! I just enabled developer options (after accidentally finding Flappy Android) and the "keep screen on while charging" option was turned on by default. Doing a test charge now, but it appears as if the screen is staying off.
Awesome!
I entered a swimming pool with my OPO in my pocket. I immediately went and bought some rice. I wasn't able to open the back completely because I didn't have the tools to remove the SIM tray.
After a few days, I tried booting it and it showed a message that the battery was too low (pic) and then it would keep rebooting itself.
I thought that the battery was messed up, so I replaced it. Now it turns out that everything works perfectly fine (screen, speakers, camera), but the new battery (and maybe even the old one) does not seem to be charging. What's even more weird is that it will only show me that it is charged 50%.
The phone seems to recognize that it is connected to a power outlet. When turned off, I can click the Power-button once and see that it is "charging" and at 50%. When turned on, it does not appear anywhere that it is charging. No notification light, nothing on the status bar, and "50% - Not charging" in Settings>Battery (when plugged in) and "50% - approx. 12 hours" (when not plugged in). Also, in Settings>Battery>Battery optimization it says that "battery optimization not available" for Google Play Services.
I have obviously plugged the battery connector back in when I replaced the battery, but I don't know if I need to replace the Micro USB Port or not. It seems like it is recognizing when it is plugged in, but it's simply not charging.
What do you think I should do? Thank you!
Phone is off, plugged in to charger, battery is out - and when I click on the power-button it still tells me that it's charging and on 50%!?
everytime i attempt to charge the phone the screen wakes up, is there a option to turn this off at all?
gets annoying after a while.
In Developer Options turn this command off. Stay Awake.
I think he means that when he bugs the phone in or puts it on a wireless charger the lock screen lights up.
I'd be interested if there was an answer as well.

yeah when i plug the charger in the screen turns on and i have to press the side button to turn off the screen again, gets irritating after a while especially when you have a app open.
i'll try that dev option and see if that changes anything.

just enabled developer mode and the option is already turned off so the issue isn't related to this.
the phone just notifies that charging haz started
switching that off wiuld become meaningless

Can't it simply do what previous Samsung phones did before? You plug in the charger it makes a sound that it's charging and that's it? What purpose would benefit anyone by waking the screen when the phone has started charging anyway? All it does is irritate the user as they have to keep pressing the side button each time the phone is left to charge.
It seems the only way to disable this is yet again root and there doesn't seem to be any other way, not even a app at least..
???
Waking the screen while charging each time is dam meaningless.
The screen should time out and turn back off or am I missing something?
No, you are not missing anything. I agree, there is no reason for the screen to come on upon starting to charge as you have an led that tells you that. It is just ANNOYING!
Yes this is annoying and I am still looking for a way to disable it. Not only does the screen turn on when I place my S8 in the cradle, when the screen timeout kicks in, the screen wakes again when the wireless charging does its animation of how much percentage is left.
Try "All My..." it contains no wake on charge. If you use wireless charging then I would reconomend using a charger limiter like "Battery Charge Limit [ROOT]" to minimize heat.
Hello
i just calibrated the battery with "advanced battery calibrator" app. in the begning of the process it noticed that do not turn on phone unless the fully charged. i turned off the phone but it automatically turned on; i calibrated with that software again and turned it off, but it automatically turned on again. i turned it off and; after fully charged i wanted to turn on the phone: but the phone so quickly turn on & off. the LG logo just blinking. when i attach the charger it turn on and i can use the phone and it show correct percent of battery. but when i remove the charger cable, it turn off after 10 second. i upgrade its rom but still the problem exists.
can anybody help me?

My guess would be your battery is bad. I've had my device since launch and have gone through 4 batteries. Each time at failure the symptoms were the same. Battery drains fast, device shuts down with random amount of battery percentage remaining then bootloops and eventually only functions when a charger is plugged in. I'm guessing you were having battery issues intially and that's why you decided to use a calibrator? The calibration process may have been the last straw and your battery is shot.
