Depends on a couple of factors:

  • When did you update?
  • What is your Battery Health Percentage?
  • What apps are consuming your battery?


It is best to post the screenshot at Settings > Battery showing the green battery graph along with the top 5 apps consuming your battery. An iPhone 12 Pro on an original battery is likely below 80% and needs to be replaced. If it has been replaced from a third party it is not likely to have the performance necessary. If you are experiencing low cellular service, more battery power is necessary and any changes in cell signal will result in increased battery demand.
