battery and clock icons
Aren't those controlled by your phone itself? They are on my Android phone at any rate. I don't see the time or battery status when the app is open. Do you need to see them? I think there is too much going on in the app already. I don't think they should add anything else.
At any rate, using the "Site Feedback and Suggestions" forum would give you a better chance of getting your suggestion noticed.
Another way to make a suggestion is to write an email to support. (Use the Contact link in Help.- https://support.chess.com/customer/portal/emails/new )
