Troubleshooting Guide: Restoring a Dead iPhone Battery to Working Condition

How do I get my dead iPhone battery to work again?

Is your iPhone’s battery dead and not responding to charging? Don’t panic! In this step-by-step guide, we will show you how to revive a dead iPhone battery and get your device up and running again. Whether you’re experiencing a completely drained battery or your iPhone won’t turn on at all, these troubleshooting steps will help you bring it back to life.

Step 1: Check the charger and cable

Before assuming that your iPhone battery is dead, it’s important to rule out any issues with the charger and cable. Make sure you’re using a genuine Apple charger and cable that are in good condition. Try using a different charger and cable to see if that solves the problem.
