BLE is still Bluetooth with is so 2.4 GHz and still can operate thru human body. However, I don't deny your experience. I think the issue is that the phone and the car are constantly scanning. But their scanning period do not overlap so it takes a moment to find eachother and communicate. During this time, what ever we think we do to change thing to that will unlock the car shouldn't be associated as cause and effect reasoning to why it's not working. I have gotten close to my car and waited with my phone in my pocket and eventually after 20 to 30 seconds the phone and the car communicate and unlocks.Its Bluetooth Low Emissions (BLE) not regular bluetooth, and I have personally experienced, several times in fact, having my phone in my back pocket, having it not work, and doing nothing else but turning sideways to bring the phone closer to the door and having it then work.
With that being said, In the past several months it has become much less reliable for me on my iPhone, after several years of working 99% of the time. Tesla stuff being Tesla stuff, I just chalk it up to some update or other. iPhones dont have a bunch of backgrounding settings, but I have checked those.
In any case, that advice was given from my own experience. Feel free to use or ignore as you wish.
However, based on your experience, there could be intentional security mechanism from Tesla with recent updates that tried to prevent hacking or spoofing or fishing. It could be that the phone and the car find each other immediately but the app uses other sensors such as gyro and proximity sensor to verify movements. This may explain why phone in backpack delays unlocking. Next time you should wait when you get to your car while your phone is in your backpack to see what happens.
