Charging and screen on - Xperia Z2 Q&A, Help & Troubleshooting

Hi all, recently my phone when on charge the screen won't turn off, even when locked it turns itself on?! Any ideas to fix..

If you have activated Developer Options then look in there to see if Stay Awake is ticked, if it is then untick it, if that is ticked then the screen will stay on when charging.

That's not ticked, it seems quite temperamental. Can't work it out!

Hmm, have you tried turning off Daydream in the display settings if you use it? Only other things I can think of are maybe a Xposed module if you use them or a app running in background.

Don't use daydream!
I've figured that it only does it from 90% to 100%?! Weird...

I have exactly the same issue, changed different cable, charger, usb ports from pc, 95% of the time it will have the same problem.

Well if there is no fix, then i'll have to take it back, as it keeps the phone very hot by keeping the screen on and off.

There is a small fix... it is to use a USB cable that has no "data capability".
I've purchased a battery pack which has a short usb cable, which has no data connectivity function (only used for charging) and that will not trigger the monitor on in anyway. For the temporary time being, I have that used to charge every time.

[SOLVED][Q] Screen stays on when charged

When I leave my GT10.1 plugged in the screen comes on. It seems to do it when it reached 100% the screen comes on and remains on till I turn it off.
Is anyone else having this problem?
No problem here, but are you still stock?
It has done it since I got it on 6/17. I am using pershoot's kernel right now.
I would backup and try a clean install of the stock rom to see if that solves it. Or you could try writing over the existing rom to save your settings.
Did you enable Settings->Applications->Development->Stay Awake by any chance?

*facepalm* I did have that setting enabled. I am going to put it back on the charger and see if that fixes it.
Boy do I feel dumb.
that setting did the trick. Thanks a million.

Display turn on while charging with 100% battery

Hey there,
i noticed that my phone turns on the screen while charging when it reaches 100%.
That is quite silly, to keep screen on for hours.
When i go to bed i will charge my phone, and everytime i wake up my screen is on.
Is there any chance to stop it?
greetings
no one?
greetings
You can use an app like smart screen off...

When you switch the screen on during charging does it go off or does it stay on?

goes on when reaching 100% and stays on till i pull the charger

Mine wont turn off at all by itself when on the charger. If a sms comes for example the screen stays on until I switch it off myself. Same happens when the charging is finished.
never had such issues

may be silly to ask but... did you uncheck "desktop mode" (may be another word, mine is a german one) under "dock"?

mine started behaving like this and the only way i could find to fix it was to do a full wipe :/ not ideal..
it's working ok though now and my "desktop mode" is checked!
I did the full wipe aswell and it was ok until i plugged it into my pc.. No differece with desktop mode. I also have a german one even though i do not live in Germany and after the full wipe all my languages on stock keaboard are gone apart from German.

X-Reality keeps getting deselected - not sure why!

Here's an odd one. It seems that something on my phone, or perhaps the Stamina mode, is causing X-Reality to become deselected.
It's a low power option in Power Management, but when the battery is charged up, it should surely re-enable it? But mine is remaining off until I go back in and turn it back on.
And in any case, I've only invoked the lower power mode a couple of times because the battery is generally so amazing.
Any ideas what it might be?
Does it only happen after the phone has entered Stamina Mode?

I've got Stamina enabled all the time. However, I don't know when it has been disabled, just that it has been the last few times I've gone in to Settings/Display.
It's still on now, so I'll try and check regularly and see when it goes.
Yh same here, stamina mode switching it off after I turned it back on.

Phone in dock, got to 100% and I've just checked - it's disabled again! Haven't even used it.

checked mine too and yeap, it's gone again. I give up, didn't exactly notice a huge difference in pictures/videos anyway.
edit: I realized that docking my phone (mimics the effect when charging with a magnetic charger), it turns on X-Reality. when I undock, it automatically gets unticked.
notification LED seems to fail randomly too. man I hope this phone isn't dying.
Solved!

Bingo! It's when you take it OUT of the dock (or disconnect a magnetic charger) that it deselects X-Reality! Well done for finding that out, as it was really confusing me.
As shown here in a very quick and rough video: https://www.youtube.com/watch?v=uFHb-bZlHK0
PS. It doesn't matter if you use Daydream or not.
my best guess is that the restrict performance option makes it such that it turns it off when unplugged.
like in you said in OP, it'd be nice if it's turned on when juice is at an acceptable level.
Sent from my D6503 using Tapatalk
I just checked and mine doesn't do that. Xreality stays checked no matter what I do. I tried USB cable, magnetic cable, restarting the phone, etc.
I've got Stamina mode enabled with restrict performance enabled. Probably that, although I'm out and can't test theory right now.
Edit: don't need to. Toggling option turns it off, so that's it. So even if you set 'restrict performance' and manually re-enable X-reality, the mag charger resets it.
Got the same problem guys. Anyway to relay this bug to Sony?
I'm on 314 btw
Sent from my D6503
Same problem on .314. Whenever I check x-reality after a night of charging the phone (although it doesn't go below my low-battery mode limit of 20%) it is always unticked! I don't charge using a magnetic dock because I don't have mine with me at the moment but even on stock USB cable it still does this. I think it may be a bug with the x-reality engine or the battery saver mode that turns it off.
So no solution at all? Do we know if it happens to Z3? So maybe with 4.4.4 will be fixed?
305
It happens on my Z3 too with the extended function turned on. Tried selecting manually, plugged in a usb charger, and plugged it out and when stamina kicked in, got deselected again!
Damn feature!

Solution is:
Settings → Power management → Stamina mode → Extended usage (have to be deselected)

[Q] Shut down sreen while charging

Hi,
This may sound stupid, but is there a way to turn off th screen while the watch is charging?
Tyanks in advance.

Well, you can either shutdown the watch (if that's an option) or uncheck "display always on" in the settings
Even with uncheck display, it still stays lit while on charger. I hope they add the option to turn it completely off in a future update.
i tried also to turn off when charging, but no luck. it turns on immediately. i tried to put it turned off in cradle ..--> starts.. turned ON and turned off during charging in cradle, same issue. it starts. there is no way to charge it turned off.
There is an option in the developers menu to turn this off and on, on the watch tap on software version 7 times and it will give you Dev settings
Sent from my D6503 using XDA Free mobile app
yes, but when the option is OFF , the screen is not 100% off.
and i also tried to switch the watch OFF during charging and no result
The only way i have managed to turn screen off whilst charging is to go into gear manager and toggle the screen always on option. This needs to be done after it has been put on charge and you will need to do this each time you charge the watch.

This is what I've been doing too. It's a pain because even when the screen is dimmed its pretty bright in a dark room.
probles with charging

obviouslly you cant shut the watch off while charging since putting it in the cradle is the way to turn it on. i charged the watch in the cradle all nite and this morning it only registered 67% battery level. how is that possible? am i doing something wrong?

You can shut it off...but then how do you charge it? I've not had any charging issues, it gets fully charged within a couple of hours.

You can use Slumber for Android Wear available on the Play Store.

Slumber is only a partial solution since it doesn't really turn off the screen completely.
Instead it just shows nothing on the screen (but its still on)
Wait? It keeps the screen on during charge? Mine was off while on the cradle, I guess it didn't charge. Which explains why the battery is almost dead.
I've been on battery for 29 hours and have 15% left, not too shabby.
Has anyone found a better solution for this yet? I find this the most frustrating part of this watch.

I agree, this is an option that should be in Android Wear and not depend on other apps.
I use Slumber and I like it very much. At least the screen is muted, although it does still glow while charging.
I'm working on a watchface of my own and I hope to include a feature to put the watch into Theater mode when charging, but at this point I'm not even sure if that is possible programatically.
Just turn on Teather Mode. Perhaps its possible to automate it using tasker?

Phone Turns On By Itself

I power off my Mate 2 every evening. In the morning, it has turned itself on. How is that possible?

No to all.???????
If its plugged it that is possible if there is a small fluctuation in power.. Connector being a little faulty. Etc.

Not plugged in. Tonight I'm going to turn it off with Rom Toolbox and see if that makes any difference.
That is very odd lol. Haven't heard that one before.
Have you set an alarm? I heard some huawei phone has this feature, it will power on itself when it reaches the time of the alarm.

No alarm. I think I will just stop turning phone off as I have to relaunch Nova each time.

Have you installed the update/preview B309? I have, and my phone seems to restart immediately every time I power it off, unless it's fully charged.

Yes. I have B309. Glad to know I'm not alone.
I have been on the lookout ever since I saw this post. There have been others reporting the issue and it is marked as fixed in the next update. We just don't know when the update will come. So, at least you know you aren't crazy.
Have this issue in 309 too. . Turned on and went into Airplane Mode.
