I have a fold3 as well, personally have found the battery life to be fine. Maybe because my previous phone was 6 years old when I switched so I had low standards for battery. Although, I definitely don't need to charge 3 times a day.

If nobody else had said fold3, I was gonna post: I have a fold3 and I love it. I can see how people could see it as a dumb gimmick, but for me it can legitimately function as my main portable media device (ebooks, internet, keeping notes, video content, sudoku, emulated games if I attach a controller, showing people pictures, etc) in a way that a regular phone would feel way too cramped for, while also just fitting in my pocket so I can take it everywhere without a second thought - which would be a much bigger pain with a regular tablet. It's just really nice having a full-sized book in my jeans pocket in a waiting room, as a painless part of my "everyday carry".

Downside (for me) is people sometimes see me fold/unfold it and want to start a conversation about how weird it is, when I'm an extreme introvert and just wanted some silent device time. I guess this might be an upside for extroverts, but then they might be less interested in being glued to a large pocket-screen in the first place.

I have a Flip 5! Got it for the form factor and it just looks cool lol. I enjoy it.

I have a Galaxy Fold 2 and it's pretty sweet. Mine doesn't have the battery issues you mentioned for your 3, though. I guess if I'm watching videos for a few hours, THEN I definitely need to charge it, but otherwise a single charge lasts all day.
