ATTN: Handheld players - are you really stopping charging at 80-90%?

I’ve been a docked player forever, but have recently found myself playing handheld quite a bit on the NS2.

I’ve occasionally planned a handheld session, and preemptively disabled the stop charging feature, but then always turn in back out as soon as I put the switch back on the dock.

For those of you who primarily, or even just semi-occasionally play handheld, do you use this feature, and why?
