Q: after charging from cpu an inadvertant restore was performed. can I retrieve messages, photos and emails

Hello fern50!,

Thanks for contributing to the Apple Support Communities.

It sounds like your iPhone was restored accidentally, and you'd like to recover data that was on the device.

If so, try restoring from an iTunes or iCloud backup using the steps in Restore your device from an iCloud or iTunes backup.

For information about the differences between iTunes and iCloud backups, see About backups in iCloud and iTunes.

Best Regards.
