I’ve had IPhones since the 4 so I should know this. I now have the IPhone Xs Max. What percentage should I let my phone get down to before I charge it?? I want to keep my battery healthy and get the best performance from it. Does it hurt to plug it in when in the car, even if the battery isn’t low? I usually try to drain it once a month before plugging it in to keep it calibrated. Is this necessary? Thanks for the tips and advice.
