You are supposed to experience battery drain for 3-4 days after EVERY update. Not sure what charging issue you are referring to:

  • Is this a MagSafe charger?
  • Are you using a wired charger?
  • Is this a third party Qi charger? That may be the issue if using a third party Qi charger.


Here is an article about the battery drain and performance issues that should be expected during the time your files are being indexed after the update.
