Battery drain issue

Go to settings Battery and look at what is using it.

Look particularly for light blue columns (screen off usage) as it could be app background usage

You may need to iodate or even delete rogue apps or turn off their background refresh setting.

My reply without typo errors. Please come back if it does not help or mark as helps/solved.

Go to settings Battery and look at what app is using it. look at last 24 hours and last 10 days.

Look particularly for light blue columns (screen off usage) as it could be app background usage.

You may need to update or even delete rogue apps or turn off their background refresh in Settings.

IOS 13.3.2 is available as of this morning.

Apologies. This is incorrect.
