An X tipster claims the Galaxy Z Flip 7 and Fold 7 could grab "highly efficient" displays to help improve battery life. The Flip 7 is rumored to stick with its old 25W charger, but it could see new "flexible glass" to help reduce its crease presence.

They also reiterate a previous claim that the Galaxy Z Flip 7 will have a larger vapor chamber than the Z Flip 6, which could also help improve its battery life. So, hopefully, the Z Flip 7 will have improved endurance, as in our Samsung Galaxy Z Flip 6 review we found the phone had “disappointing battery life.”
