Samsung Galaxy S7- If I drain the battery so its dead and remove the simcard, can it’s location be tracked down?

I got 2 questions regarding my Samsung Galaxy S7-

Q1) If I drain the battery so its dead and remove the simcard, can it’s location be tracked down? I’m asking about a dead battery vs removing the battery since you can’t remove a Samsung Galaxy S7 battery without special tools.

Q2) Does the Samsung Galaxy S7 have some sort of backup battery function where the phone will shut off before it completely drains? Or a second battery or way for your phone to be tracked even with a dead battery.

Ex: If your cell phone is on and you drive somewhere and lost your phone, it should be traceable. But if your battery is dead and you remove the simcard, my understanding is it CANNOT be traced and will only show the last point in which the phone was on or before the battery was dead…. but again, I don’t know for sure.

According to some article I googled, it says it can’t.

Can you track a cell phone with a dead battery? Unfortunately a phone with a dead battery will not respond to attempts to locate it via GPS. Lookout Mobile’ automatically records your android phone’s last known location just before the battery runs dead
