How many of your new 2024 tamagotchi connection have this battery fail?

I wanna ask you something... I'll be getting a pair of the new 2024 connection tamagotchi and im afraid now. I saw that there some people that have the battery life span really decreased and it does not last a lot... Maybe a week, or even a cluple of days, so im curious about how many people have this error in their tamagotchi.

Im trying know the chances of having a bad pair, specialy the True friends version.

What do you think? Should i be affraid or the chances of having a bad one is minimal?
