Battery health
since last few days i noticed taht my battery percentage of Iphone 11 was going down instantly so fast.. this has never happened before it was 96 day before yesterday and now it has come down to 94%.
then i updated the latest update which 14.6 version,, and received a important battery message, saying that battery helath system is recalibrating and it might take few weeks..
please explain me what needs to be done.
