How Do Mobile Phones Work?

  • CPU (Processor): The brain of the phone.
  • Battery: Gives power to the phone.
  • Display (Screen): Shows everything and lets you touch and control.
  • Mic & Speaker: Help you talk and hear during calls.
  • Software (Android/iOS): Controls everything you see and use.

Main Parts Inside a Phone

Here are the most important parts you should know:

  1. Battery - Powers the phone.
  2. Display - Shows pictures, videos, and apps.
  3. Mic - Records your voice.

Safety Rules Before Repairing

Before opening or fixing a phone, always follow these safety tips:

Turn off the phone
Never open a phone while it’s on. It can be dangerous.

Use the right tools

Don’t use kitchen tools. Use small screwdrivers, plastic openers, and tweezers.

Be careful with the battery

Never bend or press hard on the battery. It can catch fire.

Don’t use too much force
