Recently Deleted Apps appearing in battery usage despite not deleting any applications recently

Hi.

So basically, I have not used or deleted any applications for the last 2 days (I deleted Reddit 3 days ago). But apparently "Recently Deleted Apps" were responsible for draining my battery usage as seen in the images above. What is the cause of this? Is it a software error? Is it a battery problem?

I have restarted my iPhone numerous times to see if this anomaly would go away but it still won't go away.

I am worried that this problem would somehow damage my battery or even worse is a sign of some sort of malware installed on my iPhone (which I am aware is unlikely but I still worry anyways).

If anyone can ease my worries or provide a solution to my problem, that would be greatly appreciated.
