STAMINA mode does not work on my Xperia Z2 - Kikat 4.4.4 (latest version)
I found a discussion in this https://talk.sonymobile.com/t5/Xperia-Z2/Xperia-Z2-Stamina-mode-doesn-t-work-aparently/td-p/793097?sl=y&sso_no_log=y
but I can not find "Eco mode controller" in Apps list.
Anyone has any ideas? Thanks!
