iOS 13.5.1 battery drain

The battery drain from background activity in iOS 13.5.1 is horrible. Happens on several apps, currently Bloom berg and Teamsnap. Same problem on my iPad and my wife's iPhone Xs. Come on Apple, this needs to be fix now!

in that case it is apps that have not been modified to run on the new OS and have runaway background usage, Viber fir example.

or a busted phone.

Nothing in 13.5.1 itself is causing this.

So to test this ( yes effort required)

  • backup
  • restore to factory settings as though you were selling it - see https://support.apple.com/en-us/HT201351
  • Set it up with your apple account
  • Check battery usage in that vanilla environment.
  • Restore from backup.

Will do tomorrow when I see what the official apple service will say what to do next.

I am in contact with apple support on twiter but cause of the time diffrance we can't really do anything - they are trying to do Diagnostics but can't find where to start that it's not on my Iphone lol.


Cause as it is now I can't do anything with the phone as soon as I open an app or just look a a pic or settings and the phone is not connected to the power it dies.
