Some kind of widget on my lockscreen, how to disable it?

[Geiu]

Hei guys,

Some weeks ago I discovered that some kind of widget appeared on my locksreen.
Screenshot here:

On the top right there is a button that looks like a lightbulb. If I press it then it gives me the option to disable, if I press disable then it gives me a warning if I'm sure I want to disable, so I press Disable again. But when I open my screen the next time it's there again.

I have tried to find if it's connected to some app but I can't find it.

I would like to disable it for good because I think it's draining my battery too much.

I hope somebody can help me.

Thanks in advance.

If you think it's draining your battery, checking your battery stats may help identify what it is

Well, I have checked the stats but I don't know if the widget is part of the Android system or what. Because in the stats I don't see any weird or unknown programs.

Also I have read about the battery draining issue and it seems to be more linked to the battery itself. I have had the phone for a year now, I think I'm just gonna replace the battery.

Try Safe Mode, to test whether it originates in a third-party app.

Did you install any task killing apps? Anything by Cheetah Mobile?
