Samsung's new foldable smartphones Galaxy Z Fold 3 and Z Flip 3 come with a newer One UI build, specifically One UI version 3.1.1. While not a major improvement to version 3.1, One UI 3.1.1 brings several new "big" features. Among them, for example, the option in Device care, which until now was reserved for tablets Galaxy.
Specifically, this is the Protect battery function. It can be activated in Settings → Device care → Battery → More battery settings. And what does he actually do? Exactly what it says in its name – it protects the battery Galaxy Z Fold 3 or Z Flip 3 in the long term by making it impossible to charge it to more than 85% capacity.

Many recent studies have shown that recharging a lithium battery to full capacity does not benefit its life in the long term. Recharging the battery puts more strain on the battery, which results in a shorter lifespan and an increasingly poor endurance per charge.
The Protect battery function is for smartphones Galaxy new but has been around for a while for tablets Galaxy. At this point, it's not certain if it will remain exclusive to Samsung's tablets and flip phones, or if regular smartphones will also get it.
