5 Signs Your iPhone Battery Needs Replacing

Your iPhone battery is designed to retain up to 80% of its original capacity at 500 complete charge cycles. But how do you know when it's time for a replacement? Here are the five most common signs.

1. Rapid Battery Drain

If your iPhone goes from 100% to 20% in just a few hours of normal use, that's a clear sign of battery degradation. A healthy iPhone should last a full day with moderate use.

2. Unexpected Shutdowns

Does your phone shut down even when the battery shows 20% or more? This is a classic symptom of a failing battery that can no longer deliver the power your phone needs.

3. Slow Performance

Apple introduced performance management in iOS to prevent unexpected shutdowns. If your phone feels sluggish, a degraded battery might be the cause.

4. Physical Swelling

If your screen appears to be lifting away from the frame or you notice bulging, stop using the phone immediately. This is a dangerous sign of battery swelling.

5. Check Battery Health

Go to Settings > Battery > Battery Health. If Maximum Capacity is below 80%, it's time for a replacement.
