Questions about battery on iDevices

[NacSquared]

Hey guys, got a quick question regarding battery health for you.

For example, I'm currently watching a stream on twitch on my iPad. I'm right next to my iPad charger but my iPad is at 100%.

Should I leave my iPad plugged in while the stream is running, or is that bad for the battery?

This applies to all my devices (iPhone 6 & MacBook Pro), should i have the devices plugged in while doing the power hungry activity or should I let it just drain the battery and charge the device later?

Thanks in advance for any help!

Just let the battery works.
Don't keep it always at 100%: it stress the battery.
At the same time don't let it drop below 20% very often: a full recharge cycle means big stress for the battery.
Keep it constantly between 20-90% is the optimum.

Basically best not to leave it plugged in constantly and not to let it run down all the way very often. Beyond that the battery likes to be used so basically just use the phone and charge it whenever you might want for as little or as long as you want (again short of leaving it constantly plugged in).

it should be fine plugged in as it would draw power from the AC. Just be sure to cycle it every once in a while
