I guess they need to be kept in their case when not in use so they are always charged.
I guess you're right. But then I'll need to carry the charging case everyday to work. I only listen about 3-4 hours of music a day, it will be great if I can turn it off to preserve battery so it can last a full day for me without having to carry the case.
I have an Apple Watch so I can't. Ive never heard of a device (besides the smart battery case) that is always on and can't be turned off
Apple Pencil is never "off" -- it has quite the battery drain when not in use, it always seems dead when I go to use it, because it travels with me in my bag daily. I think it has a low power "sleep" mode supposedly, but I can lose 10-15% a day with Apple Pencil not even in use. I wish after charging it had a little "off" switch so I could just flip it on to auto-connect when I'm actually ready to draw.
I have an Apple Watch too, so I always have my phone Bluetooth on, unless I'm toggling Bluetooth on/off because of a finicky earbud pairing (non AirPods).
Just a small correction that you can turn the pencil off using the method I use. Swipe up control panel on iPad, toggle bluetooth off for a second and then back on. This severs connection with the pencil and its truly OFF. The only downside is, you have to plug it back in to the iPad for a moment to reactivate it.
It's very much possible that the AirPods will be turned off when you put them in the case. But when they are outside the case they must remain on as there is no way to turn them on without the case.My concern with that is A: Wasting life cycles of the AirPod batteries. B: They are constantly charging/discharging in the case and slowing draining it. It's like you can win either way!
They are off in the case, but they seem to slowly drain and when they do, the case charges them back up. I've done some rough tests but am stilling seeing what does and doesn't work. But inside the case is the only time they are actually off. They just don't hold a charge all that well it seems.
