You can also reinstall Marshmallow with Sony PC Companion, it might imReinstall Marshmallow with Sony PC Companion, it might improve the performance.

Charge your tablet to 100% and use it like you normally do. Then when the battery almost dies, take screenshots of your battery usage and post it here. Gives us better information to help you identify the problem and solve it.

I have done this before then post this theme.
But in the chat support I received only a reference to control power management manual.
After that, the manager simply close the dialog. Scorning by Sony, isn't it?)

So it will do, thank you for your support.
I lay out the screen today.

I had a similar problem with Marshmallow on Z4. I had to clean install 3 times and installed app one by one to measure the background activities. It seems that Doze does not seem to switch off the wifi at all if you put the wifi at on always and phone signals seems not as sensitive as before anymore.

Also you have to kill the location service twice to safe battery. And some background activities of news app seem cannot be regulate with Doze.

I am skipping Marshmallow on my Z3 tablets and keeping the lollipop until they put the stamina back on Marshmallow.

Hope this helps.

I got my z3 tablet yesterday running Android 5.1.1 and had the stamina mode. I updated to the exact same version as my z5 6.0.1 but im missing the stamina option under battery.
