On Lollipop the way to tell stamina is activated is a small + icon next to the battery. That was excellent on my Z3 Compact.
Now when running Marshmallow on my X Compact there's a permanent notification in the notification field when stamina is activated. It's not removable. Very annoying.
At 30% you will get a message you're battery is at that point. This one you can ignore but at 15% the only way to get rid of the irritating notification is to actually go the the stamina menu and turn it on. But if you switch stamina on at 30% you will still get the 15% message. So that makes two notifications in the field on the top of you're screen. One screaming : "You're battery has only 15% juice left." Yep duh, I already know that because the percentage of energy left in the battery is right there sitting next to the battery icon. The other one says: "Stamina is activated." Yep, duh, I already know that because I just switched it on myself.
I really can not think of any reason why we need these notifications. You can not switch them off like other apps in the settings - app messages.
Sony, please loose the stamina notifications. The small + icon next to the battery is more than enough.
And all these energy related messages are polluting the notification bar.
