Why does X-Reality keep turning off by itself? - Xperia Z2 Q&A, Help & Troubleshooting

I have a stock non-rooted Z2 and X-Reality keeps turning off by itself. I literally have to enable it everyday under display settings. Does anyone have this issue? Any idea on what might be causing it?

As far as I've noticed X-reality turns off when the device enter low power or power saving mode but doesn't turn back on when the phone is charged again. So your phone may be entering power saving mode and switching off X-reality every night! :good:

More or less. To avoid such a problem navigate to your low battery mode options and uncheck Turn off XReality when battery is on low level. Sorry for not so accurate names of options, Im using my mother tongue language on phone, but I hope you will found it

[Q] Power Saving Mode keeps changing my settings

So I have set my power saving mode to come on at 30% and for it to disable everything except wifi. The problem is that after I charge my phone back up, those settings remain disabled even though power saving mode is turned off, so I have to manually enable them each time. Is there a way around this?

What ROM and kernel is on your phone?
If you enable user specified power saving with your customized settings (30% battery => shut down everything accept wifi), and you did not disable this power saving mode, when exactly is the power saving mode disabled?
As soon as you plug in the power cable?
And is it not re-enabled automatically, after pulling the power cable out?
Sorry, but I did not exactly understand your issue.
"those settings remain disabled even though power saving mode is turned off" => Yes, that's correct. If the power saving mode is turned off, all power saving settings should be disabled.
This sounds to me like "normal" behavior.
Maybe I misunderstood something in your description.

I'm on stock 2.3.3 and KG2
And I meant that these settings do not revert themselves after I finish charging the battery. For example, at less than 30%, my power saving mode turns off syncing. But once I finish charging my phone back to 100%, the syncing is remained off, so essentially, my power saving mode never really turns itself off even after charging.
I noticed the same thing - it's very annoying to set my screen timeout to 2 minutes, and when power-save mode comes on, it gets reset to 30 seconds and stays there.
I ended up turning off almost all of the power-saving features, and setting the threshold to 5%. I'm running the stock rooted kernel with NoCIQ, so I already have a pretty substantial battery life (~24-30 hrs with normal usage and wifi at home).

Have a look at MyProfiles app from the Market.
Maybe it can help you to switch between different profiles based on system triggers.
Or use AutomateIt app to define rules when to toggle wifi, bt, gps, etc.
Just worth a try...

Thanks for the suggestion, but I kinda want to get to the root of the problem here as opposed to installing an app to mask it. Does anyone else know what's wrong with my phone?
There's nothing wrong, that's just the way it works, it change your setting when activates but doesn't change them back.
I no longer use it, since I have GPS/wifi/BT disabled unless I use them anyway.

Wifi never sleeps

then easy battery saver is messing up settings, there must be some setting about wifi sleep policy in easy battery saver.

Lol this is really easy, install easy battery saver from the market. I think you need to install easy task killer first. Then in the easy battery saver app, choose either general or intelligent power saving mode. There, your WiFi will turned off automatically when your phone sleeps. I use it and it works

backup apps and then do a factory reset?
Ye that should work!
Update: reset done still the same.. Repaired the phone via SE pc companion no luck, still WiFi won't sleep when screen's off...

last option left is reflash via wotanserver
same problem here, but the solution is simple.. really simple..
I take it you're on Inteli Mode right?
you just need to add the wireless widget then stop and start the wireless again
then your wireless will sleep when the display is turn off
cheers

[Q] Screen is always Dim

When I unlock the phone it always starts up very dim and sometimes it turns bright sometimes it doesn't. I have auto-brightness off and I have my brightness set to 100%. I have to move the slider off of 100% and back to 100% to get it that bright. It is very weird. Anybody know how to fix this?
I have the same problem.

Been unchecked since day 1. Still does it. Possible that I have a defective unit?

Is it dim on the home screen or certain apps? cuz internet browser, video etc got their own brightness settings built in that you have to change from the settings within the app.

It is dim from the lock screen. Everything once I unlock it is dim. If I lock and unlock the phone like 3 times fast it is fine, but it's a pain in the ass. I'll see if I can take a video of it later when I get home.
I know you said "everything" but try to go to internet browser and disable "auto-brightness" under brightness setting.
Also upgrade your firmware to the latest one to see if that help. My Smart detect is not working and after upgraded it work every single time plus the cell stand by is much improved
I just got my phone back from service, they updated to LF5 - so far it has solved my proplems with dim
I have had 2 handsets that do this now. Its really annoying especially when you are outside.
Basically what is happening is that when your screen dims down before it goes off thats what is happening when you unlock the phone.
I can be using it for 5-10 secs before the full brightness kicks in.
It has nothing to do with power saver or internet. Just running through the home pages and apps list it is doing it.
I am on the latest firmware too.
Does anyone know whats causing it? Is it just a faulty handset (or 2)?
Mine the same. I don't think there bad devices I think its just software related tbh

Well im glad some others of you have experianced this also.
I just hope its something that will be fixed in an update.

[Q] Stamina Mode

Do you usually turning on the stamina mode settings in your Z2?

My stamina mode is always on but appears not to work at all. I keep getting notifications on both wifi and LTE from all apps that can produce them (not only whitelisted), and I get them immediately even when the "queue background data" is on.
I tend to be forgiving because battery life is fantastic. With my normal use I usually don't go under 60% at the end of the day. The phone uses maybe 0.5% / h when idle.
Indeed, stamina mode does prolong the battery. I got 2days 18hours till10% on stamina mode without any wifi, but on 3G.
Always on with around 8 apps on the white list. Get 2 days of normal day to day use. A little less if on heavy usage

Always on, but as someone stated, i dont see it working. Dont get me wrong, battery life is amazing, just that my background data seems to be working same way doesnt matter stamina on or off.. for example i have torrent app, its not on whitelist, still downloads just fine after phone goes to sleep.
Correct me if I'm wrong, but if you want Stamina mode to always be on you have to change the setting:
Settings > Power management > STAMINA mode > Activation
to 100%
I did some tests because I was confused after reading the manual, and it appears to me that just toggling STAMINA mode to "on" does not turn it on permanently. It still waits for the battery level to drop to the activation threshold you set.
I personally set mine to 20% because I don't want STAMINA mode on all the time.
Let us know if you know more about this or experiment more and get some results. The manual is really not very clear on STAMINA mode.

Good observation, I haven't use the stamina mode since it came out of the box. How was the battery life when Stamina mode is on?

Great. I'm a little curious about the battery life of the new HTC M8 if they can also get 2 days in stamina mode? Same settings as yours?

It seemed very good, maybe half the drain of regular mode, but I have limited experience because the Z2 battery is so good I rarely go below 20% :victory:
Hey guys, yesterday I just got my third Z2 due to faults with the others and I simply don't understand what is wrong with this phone! My estimated time with stamina mode is down to 1 day and a few hours again down from 6 days yesterday night! Is it the way I am charging it or is it just buggy software? I don't have any apps I don't need on my phone and even tap to wake is off. The battery works normally I guess although it is draining a bit fast (7% in 30 minutes while using it) but I don't understand what could be causing stamina mode to play up!
Is there a work around for the notification lights not working as normal in stamina mode. Its the only thing that stops me using it daily.

Yes, you need to install Xposed Framework and load the Xperia Stamina LED module. You'll need to be rooted first however.

I've seen this "eco controller" in previous Xperia models' forums, but couldn't find it on the Z2.
Am I missing something?

Power Saving Mode Turning on Automatically

Is anyone else noticing that the power saving mode turns on automatically? I can't figure out what is causing this but it's driving me crazy.
This is a diagnostic question: is this happening when your battery level is over 50%? Or is it possible the battery has gone below the trigger level?
Try calibrating the battery and check your settings. Disable low battery conservation.
Clear system cache.

When you go to Settings --> Battery --> 3-dots menu and you click on "Automatisation", there are 3 options and one is about auto-power saving mode according to your usage
