After a day usage 6.5 hours SOT

Thank you. Wait for the LTE, the price sure drop like hell....common for Sony.

Just read the review in Taiwanese forum, mobile01. I notice the settings has black background too, which means is older version. The following is the battery test and the translation.

Those who wants to wait for lte version of Xperia z ultra better dont go and test this sexy phone. If not u will surely end up buying it like me if u have enough budget. Is too good the screen and the speed and the built quality of this phone is the best I have seen at the moment. Is so light to hold in hands also compare to note 2

You have a XZ and you are asking me this question ???

With Sony’s Battery STAMINA Mode, you can extend the standby time of your Xperia by more than four times. With Battery STAMINA Mode turned on, the background activities of most applications are reduced when you turn off the screen.

Battery life is a very important factor for many consumers, and this is something Sony has been working hard to improve. A lot of the battery power on a smartphone or tablet is consumed by background activities in apps and games when the device is not in use. Now with the new Battery STAMINA Mode enabled, apps are not allowed to synchronise and check for notifications and incoming messages when the screen is off, something that normally consumes quite a lot of power while your phone is resting in your pocket.

Starting one minute after the screen has been turned off, data traffic is automatically blocked and background activities are prevented from waking up the system. And then when you turn on the screen, the activities will resume again instantly. And as the IP address for your phone is kept, you will immediately have network access.  This all makes it possible to bring you notifications when you need them and have time to look at the screen, and not while the phone is tucked away.
When Battery STAMINA Mode is on, you will still receive phone calls, SMS text messages and MMS notifications at all times. The preinstalled Calendar app and Alarm notifications will also work as normal, while the LED will only illuminate to indicate low battery.

I have used so many other Androids ( HTC, Samsung, Dell, Asus , Nexus etc ) - ONLY Sony's built in power management works perfectly.

ya sony is fast and they r willing to announce their commitment in releasing 4.3 for their flagship device
unlike HTC and Samsung, kept slient oni... 
even if they said they r going to release 4.3... we have to wait for 1year for it

if u hv time & interest, google why XDA elite developer all jump ship
nice story there... case are lead by CM head
Paranoid Android!!! (true tablet, pie, halo)
and dont forget MIUI!!!

Other phones you need to use 3rd party app but than none of them can ever match Xperia built in stamina mode

from wat i see S4 Google Edition is S4 minus bloatware oni

thou, google sell this phone officially, but update does not come from their channel
still have to depend on samsung... same for htc1ge

currently only nexus devices is the fastest update u can get from google,
ohh ur link is the leak version... no official

There is no such thing as LTE version from sony malaysia for this phone yet..definetly wrong info...

Users oversea reported sleep to death issue, by pressing the button, only backlight but nothing appear, anyone experience this kind of problem?

Exactly, Dell Streak i couldn't recall the name.. hehe

Phone prices will keep on dropping. That's a well known fact.
Just get what you can afford at the moment. Normally, the waiting game is played when one person's affordability is limited to an extent.

naked double sided glass oozes class~! go NAKED~!  and we can also wash and rinse our phone thoroughly naked~!  do you wear any clothes when your bathing? 

Very bad. Took in my garden with slight light from nearby street lamp. Malu to even post it
Test yourself to assess
Anyway I rarely use phone to take photos. Definitely can say unusable without flash at very low light
I have posted one shot yesterday taken under average low light n still acceptable

Haha! On the way!

This also made me  about sony..

maybe need extra module to fit in new triluminous display, so no space to put LED flash and maintain 6.5mm thickness imo..

Wow.. XZU family getting bigger by the hour!

sell off the S3 only lah.. XZ keep.. two awesome looking phones side by side.. I also sold of my HTC One X but kept my XZ..

happened to me once, i shall ask them not to get me gadgets anymore~!
it almost fell when i was squatting
