Should I Upgrade to the S25U?

I currently have a ZFlip 5 and been enjoying it for over a year now. Only issue I've had is with the screen protector bubbling which I replaced on my own a few months ago and no issues since.

I still owe $400 on the phone but Verizon is offering $1000 trade in for the pre-order of the S25U, which I think is an amazing deal.

The only complaint I have with the ZFlip 5 is the battery life, and just worried it might die on me any day now based on its reputation. Would I be missing a good opportunity with the trade-in and pushing my luck keeping the flip for much longer?

Edit: I actually I realized I currently have a free credit applied to my account each month to cover the cost of the ZFlip as part of a trade-in deal when I first purchased the phone. If I want to trade in the Flip now, I lose the remaining credit and have to pay the $400 upfront out of pocket... So maybe I should just try my luck and keep the phone instead of burning money.
