When to replace your iPhone battery 

Newer iPhone models use rechargeable lithium ion batteries, which are lightweight and faster-charging than ever. But while this advanced tech helps mitigate reduced performance from wear and time, all batteries degrade over time. That means even your iPhone battery won't last forever: after a while, it slows down, and a full charge doesn't last as long as it used to. 

But how do you know when it's time for an iPhone battery replacement? Here’s a list of signs to keep an eye out for from Verizon Tech Coach experts. 

4 signs it’s time to replace your iPhone battery 


1. Short iPhone Battery Life


If your phone constantly needs charging and doesn't last a day, it might be the battery. 


2. Sluggish Performance

Slow apps or unexpected shutdowns can indicate a battery issue. 


3. Poor Battery Capacity

Go to Settings > Battery > Battery Health to see how your battery is doing. Look for the maximum capacity percentage. For a healthy battery, it should be above 80%. 


4. Degraded Battery Health

If you see a message saying, "Your battery is supporting normal peak performance," you're good—that means everything is normal. But if you see a message about unexpected shutdowns or degraded battery health, like “Your battery's health is significantly degraded” or “This iPhone is unable to determine battery health, it may be time for a new iPhone battery.

If you do wind up needing a battery replacement, don’t fret. When done by a professional, replacing your iPhone battery is easy and affordable.
