The main idea behind this is to have another day or two out of your battery.

By user or by battery percentage have the phone turn into a rescue sloep, strike sails, batten down the hatches.

• Turn off all unnecessary hardware
  • WLan, BT, Compass, GPS, lightsensor, mobile-data, vibrator, TOH ...
• Disable software
  • stop media-player, browser, gallery, camera, etc
• switch hardware to low power states
  • what is the lowest power-state of the modem, GSM? Lower screen brightness.
• disable launcher
  • only favourtites bar available and that is phone - msg - docs - people
• lock-screen pulley
  • let it have (bottom to top) silent - phone - settings (maybe a fourth but I can not think of any needed in such state)

Rescue Sloeps do neither have an engine nor a proper rudder, just some paddles.

  1. only favourtites favourites bar available and that is phone - msg - docs - people
• have some preset apps on home-screen that cannot be closed (this would need a watchdog so probably not a good idea)
• lock-screen pulley
  • let it have (bottom to top) silent - phone - settings (maybe a fourth calendar - settings

This is not meant as a power-saving mode but I can not think of any needed in such state) UI/UX restrictions by locking down the hardware and the software to a point where you will still be able to send texts, do calls, show your boarding pass or train-tickets and use your calendar for another day or two.
