There are a variety of ways for one to remove all contacts completely from an iPhone. One of the easiest ways is to download the 'Spring Clean' app. The app will bring up the full contact list and one can select all and delete. Many other processes do not completely clear the contacts.
It shouldn't because all your doing is turning it on and off
Yes there are many Apps out there ex: Find My iPhone and also if you have iCloud account setup you can remotely erase the data from lost/stolen iPhones
Yes, well there are a couple of options, but i think. You should just erase the whole phone.
To erase everything from your iPhone before selling it, follow these steps: Back up your data – Use iCloud or MobiKin Assistant for iOS to save your photos, contacts, messages, and apps. Sign out of iCloud and Apple ID – Go to Settings > [your name] > Sign Out. This disables Activation Lock. Turn off Find My iPhone – In Settings > [your name] > Find My > Find My iPhone, switch it off. Erase all content and settings – Go to Settings > General > Transfer or Reset iPhone > Erase All Content and Settings. Confirm your choice. Remove SIM card – Take out your SIM card before handing the device over. After this, your iPhone will reset to factory settings, ready for a new owner.
No. Replacing the battery will not wipe the phone. Make sure the phone is off before you disconnect the battery though!

All you have todo is attach the iPhone to your computer insure iTunes is open and then select restore to factory settings options, which will reset the handset and erase ALL previous data.
Dry erase markers - it can erase off of anything, like Boards, Hands, etc... Wet Erase markers - it will be a little harder for people to take off of anything.
No, updating your iPhone to the latest iOS does not erase your data. All your apps, photos, messages, and settings remain intact. However, it’s always recommended to back up your iPhone via iCloud or your computer before updating, just in case something goes wrong during the update. Major updates are generally safe, but backups give extra protection against rare errors like interrupted downloads, software glitches, or unexpected restarts. This way, even if an issue occurs, you can quickly restore your iPhone without losing important data.
