3. Replace the battery

Still, your iPhone won’t turn ON after battery replacement? Then you might be dealing with a faulty battery. Even though it’s rare, it happens.

You should consider installing another battery immediately. The best way to go about it is to take the iPhone to a certified Apple technician. They will get you a good Apple battery and install it without causing any damage or risk.

NOTE: For iPhone XS, iPhone XS Max, iPhone XR, and later versions, you can check if the battery is genuine by going to “Settings”, then “Battery”, and finally, “Battery Health”. If you get the message below then the battery isn’t new or genuine.

“Unable to verify this iPhone has a genuine Apple battery. Health information not available for this battery.”

4. Calibrate your new battery

If you were wondering what to do after replacing an iPhone battery to avoid issues, start with calibrating the new battery. This is as simple as draining the battery until it dies then charge it up to 100% without any interruptions. It helps to jumpstart a new battery in an old iPhone.

This is also known as resetting the iPhone battery. You should consider doing it every few months to keep the battery percentage accurate.

5. Turn ON Assistive Touch

This solution will temporarily help you when the home button on your iPhone is not working after battery replacement. It creates a virtual home button that you can use to navigate.

Here is the guide to activate the assistive touch function:

  • Open the Settings app.
  • Go to “General”.
  • Click on “Accessibility”.
  • Click on “Physical & Motor”.
  • Select “Assistive Touch”.
  • Go back and check if the iPhone is working.

6. Contact Apple Support

In case everything else fails, reach out to Apple Support. Tell them about your problem, when it started, and the solutions you’ve tried in vain. They’re better-placed to know what to do because of their deep knowledge and understanding of iDevices. Plus, you’ll be sure of getting a genuine Apple battery replacement.

Remember to carry your warrant if it’s still valid when visiting any of the Apple stores. It’ll save you a considerable amount of fees.
