I liked the size and idea of the flip phone. I was disappointed in the following, 8mg memory, screen size, but most of all the battery. After about 11 hours it went down to 62% and I even kept usage down. Enough to return the phone.
I leave my Z Flip on medium power saving with no brightness decrease and the battery life has been much improved with no noticeable difference in performance. I can still have pokemon go in a transparent pop-up window over reddit while listening to a youtube video with no hiccups
