I noticed 2 items in your screenshot.
There is an update that your iPhone is apparently still processing, which could affect both battery life, and thermal performance. Thermal performance is how your iPhone responds to (high) temperatures.
And, further down, the last time your iPhone was charging, it stalled at 96%, due to high temperatures inside your iPhone.
The two items are likely related... Not really a problem, as your iPhone should react to high temperatures. I would be surprised if you have never seen a screen message telling you that your iPhone temporarily stopped responding because of high temperatures, or another message similar to that.
Have you tried restarting your iPhone (Shut off, then start up again). That might clear that software message, or make it work more quickly, finishing up the processing of that software update.
