As released by Xperia Blog, Sony Mobile has started rolling out a new experimental update for the Xperia X Concept, which carries the build number of 38.3.A.0.83. One of the highlights in this build is the introduction of "Battery Saver."

The improved "Battery Saver" feature will revive some of the functionalities of the old Stamina mode that was initially integrated on early operating system of Xperia devices, before being replaced by Doze mode in the introduction of Android Marshmallow update.

With Sony fans asking for the Stamina mode to run on Xperia X's upcoming software, the new Battery Saver feature will bring back some of the customizability of STAMINA mode, such as reducing power consumption without slowing down the phone or having a negative impact on performance, Softpedia News reported.

Through the "Battery Saver" feature, users can customize how their battery will function below 50 percent of remaining power. It gives several options of squeezing more battery life like turning off Wi-Fi, Bluetooth, GPS, auto-sync and adjusting brightness/screen timeout. Upon receiving the update, Xperia X users can access this feature by navigating Settings>Battery> Battery Saver.

On another note, the said experimental update also brings new improvement on the camera settings, including new quick settings and camera app shortcuts. The new shortcut allows users to record videos or to take selfie picture in a snap.

Besides, Sony has also expanded VoLTE support for Spain (Vodafone) and UK (EE/Three) users.

Earlier, the Concept update also updated the Experimental track with an improved display setting, dubbed as "Night Light," which will ease reading contents at night. This feature can be activated through the Xperia X's display settings, which will then tint the screen with a pink-ish amber colour during night time.

The said update on Xperia X users came in build number 38.3.A.0.66, which also came with security patches, new version of Xperia Home Launcher, and bug fixes. This update is has a download size of 47.4MB.
