Pro tip: the guy at the phone repair kiosk in Burbank told me to stop trusting the battery health number on my iPhone
He said the percentage is just a guess the phone makes, and that's why my 2 year old battery read 89% while dying by 2pm. Now I check the charge cycles in the settings instead, and this one had 780. Anyone know what cycle count actually counts as needing a swap?
Wait, you can see the cycle count in settings now? I had no clue that was even there, I always just stared at the battery health percent like an idiot. My XR is almost three years old and the health still says 91%, but it drops from full to 20% in like four hours, so that number is clearly garbage. I'm gonna go dig through my settings right now and check the cycles, because if yours hit 780 and was dying by 2pm, mine has to be in the same ballpark.
