I have a normal Google Android phone that i noticed runs out of batteries so quickly even if turned off. So I did a quick experiment.
I removed the battery for a few days. Wouldn't you know it, the charge was exactly as I left it, unlike before. Makes you wonder what exactly that phone is doing using power while supposedly turned off.
All phones are running all the time, even when turned off. Some do a better job of conserving battery than others. It also depends on what you consider off, some consider it off by just turning off the screen, that's not off. It will use power that way. A full power down shuts most things off, but some things continue to run, as in the power button these days no longer adds / cuts power, it just goes to a chip that wakes up the system. Generally it is just in very low power mode, and sometimes that doesn't work all that well.
This is the actual answer.
Agree, 100% confirmed that they can find your location even when phone is off. Whether that "feature" is always activated, or it sends a signal once an hour or something is something I do not know.
Noticed some weird battery-draining patterns in the last month. Wondering if it’s Apple’s way of trying to get me to update the phone. I also have a flip phone that I can use a burner. I’d recommend having a back-up device soon if you can!
Burners don't work if they really wanted to get you. It's just an inconvenience for them so they pick on someone else.
I did a big update on my old iPhone. Immediately after, it wouldn’t hold the battery for even half a day. I was forced to upgrade. Guy at phone store said that it’s purposeful, and disgusting. So I don’t do updates now with my new(er) phone

There are many apps that try to phone home with data even if the phone is turned off You would have to wipe these spying apps to reduce power usage.
I have a Samsung phone I haven't registered nor bought data time for, I bought it for a backup, and keep it powered off. But when I power it up, it keeps complaining that it can't reach its masters. Which include Google and Samsung, and even though it wasn't connected, it keeps telling me that there are new updates to download.
They are active and trying to connect even if powered off.
Mine runs out faster whenever i point it at my peenis. I heard that Tim Apple might be a gay.
