After completing these steps, you’ll be presented with information about your iPhone 15’s battery health, including its maximum capacity and peak performance capability.

Tips for Maintaining Battery Health on iPhone 15

  • Avoid extreme temperatures, both hot and cold, as they can negatively affect your battery’s performance.
  • If you’re not using your iPhone 15 for an extended period, try to store it half-charged.
  • Regularly updating your iOS can help manage battery health more efficiently.
  • Optimize your settings by dimming your screen’s brightness and turning off background app refresh.
  • Consider using low power mode when you don’t need your phone to function at full capacity.

Frequently Asked Questions

What does maximum capacity mean?

Maximum capacity refers to the percentage of charge your battery can hold compared to when it was new.

The closer this percentage is to 100%, the better. As batteries age, they can’t hold as much charge, which means your phone won’t last as long between charges.

Is it bad if my battery’s maximum capacity is low?

A low maximum capacity indicates that your battery’s health has deteriorated and can’t hold as much charge as it used to.

While it’s not necessarily "bad," it does mean you may experience reduced battery life and might want to consider replacing the battery.

How often should I check my battery’s health?

There’s no set rule, but checking every few months can give you a good idea of how your battery is holding up.

Regular checks can help you anticipate when you might need a replacement, so you’re not caught off guard.

Can I improve my battery’s health?

While you can’t reverse wear, you can slow it down by following good charging practices and taking care of your iPhone.

Avoiding full discharges and not leaving your phone plugged in all the time are good starting points.

Will Apple replace my battery for free?

It depends on your warranty and whether your battery falls under any existing recall or service program.

If your iPhone is out of warranty, you’ll likely have to pay for a battery replacement.


  1. Open Settings.
  2. Scroll to ‘Battery’.

Whether you’re an avid photographer, a social media enthusiast, or someone who relies on their phone for work, keeping an eye on your battery health ensures that your iPhone 15 remains a reliable companion.

If your battery health is low, don’t panic. Batteries are consumable components that can be replaced. Consider visiting an Apple Store or an authorized service provider for a professional assessment. If you’re eligible for a replacement, they’ll sort you out in no time.
