Power management
The KitKat “Power management” setting is the same as Jelly Bean, however the option to show the battery level percentage is removed. This is not surprising as Sony allows you to choose which status bar icons to include via the Personalisation menu.

The STAMINA mode icon from Jelly Bean is no more. Instead, we now have a + symbol next to the battery icon to indicate that STAMINA mode is enabled.
