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!

I think they renamed the Eco mode controller app with the 4.4.4 update to Stamina mode... So scroll down until you find that app. Take note of the estimated days and hours before you force stop, clear cache and restart your device. activate stamina mode again after boot and note the change in estimated days and hours. Hope this helps!


This has happened twice since last Wednesday. Thankfully, I know how to fix it but not cure it.

  1. Go into the app settings and scroll down to Stamina Mode
  2. Force Stop the app
  3. Clear the data
  4. Reboot the phone

I have had to do it just now for the second time since 4.4.4 and it is a software issue. It ran for 12 hours with stamina mode at 98% to 5 days 4 hours after clearing the data and rebooting.
