The current automatic backup attempts to backup your files after every edit and thus (based on my settings) attempts to render to pdf after every single edit. This constant rendering and uploading rapidly drains the iPad battery to the point where I lose about 20-30% per hour of use and as a side effect makes the device very hot and uncomfortable to use.

Instead, it would be good to have an option to either schedule a backup (i.e. once an hour, once a day, etc) or have a cooldown option where a document won't be backed up until say 5 minutes of no activity has passed.

As it stands I have disabled automatic backup because it drains the battery too rapidly.
