Stamina mode not working after 5 days

[hsantoso]

Hi, I'm hoping Sony staff will read this and pass it to the software developer for software update.

I have had my Xperia Z for 5 days, but suddenly the stamina mode has stopped working, and this happening to some other people as well, so this is known problem.

I tried to toggle off and on, but the figure of stamina mode didn't change at all.

Really hoping software update will fix this, as this is one of main features of the phone.

I think I have the same problem.

But I think stamina mode is actually working.

Only the standby time reported on the page where Stamina Mode is enabled is not correct.

Which is annoying.

I have reinstalled the phone software but it did not help. Neither was the software update released in Russia of any help.

The reported Standby time with 100% battery drops from 5+ days to 5 hours in several days after the software installation.
Some software glitch.

1. Go To Settings>Apps>All>

2. Force Stop the "Eco Mode Controller"

3. Clear Data and Cacher

4. Shutdown your phone. Wait 30secs. Power up again.

guys go read what I posted here - stamina mode will react to your usage pattern and change accordingly

So I've been on 26% per cent for the past few hours since trying this. It's a perfectly horizontal line on my battery usage graph. Very pleased 🙂
