Cellular phones contain a variety of electronics circuitry. Along with the battery, there are lots of digital circuits, many of which are microprocessors or microprocessor controlled. There are a few "token" analog circuits that handle the incoming and outgoing audio. Additionally, there are a number of RF (radio frequency) circuits that handle do the transmitting and the receiving of the signals. Without getting too technical, that's the wrap.

How do magnets work in phones?
Many cell phones do not have any magnets inside, and are completely unaffected when normal magnets are placed near them. However, magnets are used with other cell phones in a variety of ways. Many folding or sliding cell phones have magnets inside to hold them closed in a way that is easy to open. The speaker in the cell phone may be the kind of speaker that has a small magnet inside. As far as I know, the microphone on all cell phones is of the "electret" type that does not include any batteries; cell phones don't use the other kinds of microphones that include batteries. Many cell phones have a small motor inside that is used when the cell phone is set to "vibrate". That motor typically has a permanent magnet inside. Some cell phones, when an external magnet is placed in the middle, turn off the screen and go into a low-power state and ignore button presses. They are designed to do this so that when they are placed in a cell phone holster (most of which have a small magnet to hold them shut) and then the buttons are accidentally bumped, they don't accidentally do something that would drain the battery.
