When does an old iPhone become unsafe to use?

Some people upgrade to a new iPhone every year, to get the latest cameras or other features. But if you’re like most people, you keep your phone for several years before upgrading to a newer model. Perhaps you mainly use your iPhone for the basics, or feel that as long as it isn’t broken and the battery still holds a charge, there’s no real reason to upgrade. (In fact, Apple will even replace the battery for you at a reasonable price, if yours has lost too much of its capacity.)

However, you might not be aware that there’s a real danger in using an iPhone for too long.
