SD has pass through charging, so once the battery is fully charged and also while it is plugged in, you aren't powering it through the battery like cell phones and most laptops do.

That's how nearly all modern devices work. Li-Ion can't be charged and discharged simultaneously. There is circuitry to split the power between the battery and the device when it's being charged.

Cheaper devices will just stop charging when you use them or they won't work at all when plugged in.

This is flat out not true for most phones. Most phones will charge to 100% and continously charge/discharge if still plugged in. Over the last couple years there's been some phones that will allow pass through/bypass charging. Iphones don't do it at all. Only some android phones.
