Stamina mode problem

[RFXMariam]

Well i got a warning that (download music information) app disabled or made stamina mode don't work . So i dont use this app often and i use it sometimes but I think the only way to make stamina mode work is to force stop it..Is there any other way???, And if i force stopeed the download music info, would it work again??thank you

Could you take a screenshot of the error?

Screenshot = press and hold power & volume down at the same time 

you are not going to damage your phone if you force close an app

Well. Thank you!! I actually cant screen shot cuz the warning didnt come again so i will just force stop the app

If you get any more erros you could re-install the latest updates, also if you have taskillers, antivirus, battery apps, etc, they could be creating this issues

I'm sorry but isn't there any other solution? If i cleared the app's data would everything be fine?

You could try this to reset stamina mode:

First,disable stamina mode.After,go to settings-apps-all-eco mode controller,force stop it and clear data.Restart your phone and enable stamina again.
