Note that many phones batteries are not user removable.
Buy a ton of cookies,eat the cookies or not,put the phone in the tin and put the lid on tight.
Or just leave the phone at home when going out for nefarious deeds. "They" will assume you are at home watching the television.
If the television reports that it wasn't running during the time of interest, you can always claim that you were reading a book. Or you could leave the television on while you are gone. Courtesy tip: turn down the volume.
If the traffic camera spots your car at an intersection and manages to read the license plate, it might draw unwanted attention, but "they" still do not know who was in the car.
You could paint your license plates with clear nail polish to defeat the IR scanners, like the Dutch used to do. That might still work.
Street cameras might catch a glimpse of you on the sidewalk, but the resolution is terrible and facial recognition algorithms are extremely unreliable. Wear different hats and some cheap reading glasses. Dress to blend with your surroundings.
No worries then.
