Hi, Have you restarted your iPhone? A couple things to note. Battery Optimization is a software check that monitors your normal charging behaviour and determines when to charge it to 100% not long before you'd normally start using it. For example, if you plugged your iPhone in before bed, and you normally awake at 6:00 am, the iPhone will charge to about 80% in the first one to two hours, then turn off the charging process until about an hour before you wake in order to complete the charge to 100%. Turning it off can sometimes hurt battery health. Yes, I have heard some mention that turning it off improves how long the iPhone retains a charge, but I believe that this is no longer the case. Your battery gets the equivalent of about 500 charge cycles of life. No matter if you charge it to 50% 1000 times, or to 100% 500 times. Losing 17% from noon to 7:40 is not really that bad. At that rate, you would get approximately 48 hours on a full charge. Any time you can get two full days out of a phone battery in normal use cases is excellent.

Since monday this week my Iphone has been in a strange battery drain which i wasn’t prepared for. It want from 100% on monday to 41% today which for me isn’t normal. And i then charged it to 80% at 12PM and now its 7.41 PM and the battery is att 63%. THe battery optimization is turned off, i have power saving mode on. I have deactivated app background refresh. Normally i don’t have Mobile or Cellular Data on while at home. Nor do i have bluetooth on. I turn off WIFI when out and about and turn on Celular data and use bluetooth while listening to music. It just happened and i am not really sure why. I’ve had it for a year and i thought it should keep charging a bit longer. THe battery healt tells me i am ok. I use to charge at 50% so i wont destroy my battery. Maybe this has destroyd it. Any ideas exept for contacting apple support. /A -- The following information is important for all members of the Mac Visionaries list.
