Is it permitted to touch a turned-off cell phone on Shabbat?

Hello,

A cell phone is considered a tool whose use is prohibited on Shabbat (Shemirat Shabbat Kehilchata, part 1, chapter 28, section 34), and therefore it may be moved for its own use or for the use of its place, as explained in Shulchan Aruch, Orach Chaim (section 308, paragraph 3). The same applies to a pencil.

With blessings,

Hillel Meirs
