Is it possible to disable all funktions in the loocking screen, even turn off button (also for security reasons if lost cannot be turned of until code entered or battery low....)?

No. However, turning off the phone is not the only thing that will prevent Find My iPhone from finding the phone. Being out of range of a Wifi or Cellular connection will do the same thing.

Also, with Find My iPhone, you can set up a "pending" action even if the device is offiline (Lost Mode or Erase Device), so when it does come back online, the action will be executed.

Well, the answer is still No. How would you prevent the device from never turning off when you had it in your possession? We already have a myriad of complaints about battery life. If the device never turned off, the battery wouldn't last more than a few hours....

Yes of course, i know... havn`t lost it but however makes it harder to steal (get bettery out of it or find an area with no cellular connection which are well developed here isnt that easy as just to turn off the device).

It only makes it marginally harder to steal. There are many ways to defeat Find my iPhone; turning it off is only one of them. Others:

• Remove the SIM
• Wrap in aluminum foil
• Drop in a shoplifter's bag or backpack that is metal lined
• Run the battery down
• Connect to a computer and restore the phone

Requiring a passcode to turn the phone off would also make the millions of users whose phone was not stolen very annoyed that they can't easily turn off their phone.
