3 Not Cleaning It

Your iPhone is filthy. That’s not a personal attack on your hygiene habits — it’s just the unfortunate truth. According to microbiologists at the University of Arizona, the average iPhone probably carries up to 10 times more bacteria than found on toilet seats or pet food bowls.

To be clear, while your iPhone has a ton of germs on it, those germs won’t get you sick. But problems arise if you lend out your iPhone frequently, or if the device in question is shared among a group of users. Do yourself — and everyone around you — a favor and sanitize your device every now and then.
