Just preordered the Fold 4. The Ultra was easily the worst Galaxy phone I’ve had and I’ve had all of them since OG. Despite all the tips and tricks in these threads, my battery life has been terrible from jump. Can barely make it thru a day and I’m on WiFi most of the time. Signal strength, despite Samsung’s claims to the contrary, is so bad it reminds me of the early days of cell phones in the 90s. Random reboots and the unusable screen in bright sunlight to top it off. Things have been so bad I even tried a 13 Pro Max for 30 days but couldn’t handle iOS.
Hoping the new generation of chip on the Fold 4 will restore my faith in Samsung.
