Personally the only time I turn it off is if I am putting it in the case. Even then if it’s just a 15 minute car ride to a friend’s house I might just leave it on.

It’s also rare for me to go more than 2 days without playing it, and I mostly play around my house where I have USB cables around to plug it in if need be, so battery isn’t a huge concern. In fact I usually have the battery saving feature set to limit it to 80% charge.

The only reason I really turn it off in the case is our if heat concerns, and I suspect that’a just me being over protective. I guess the other thing is that there could be security and privacy concerns from carrying around a device with WiFi and/or Bluetooth on.
