When should I replace my iPhone battery?

According to Apple and general recommendations, you should consider replacing your iPhone battery when its “Maximum Capacity” drops below 80%. @

Here’s a breakdown of what that means and how to check:

1. The 80% Rule:

• Apple designs its batteries to retain at least 80% of their original capacity after 500 complete charge cycles (for most models). ©
• When your battery’s capacity falls below this 80% threshold, it can lead to noticeable performance issues, such as:
• Shorter battery life, requiring more frequent charging.
• Slower app performance.
• Dimmer screen brightness. ®
• Unexpected shutdowns. O
• At this point, Apple’s software may also start
  “throttling” the phone’s performance to prevent unexpected shutdowns, which can make yourphone feel sluggish.

  2. How to Check Your Battery Health:

  • Go to Settings on your iPhone. &
  • Tap on Battery.
  • Tap on Battery Health & Charging (or just Battery
    Health on older iOS versions). ©
  • You will see a “Maximum Capacity” percentage.
    This number indicates the current battery capacity relative to when it was new. @ +1

  3. Other Factors to Consider:

  • Your experience: Even if your battery health is above 80%, you might find that the battery life is no longer meeting your needs. If you find yourself constantly looking for a charger or a power bank, it might be a good time to get a replacement, regardless of the percentage.
  • • Apple Store or an Apple Authorized Service Provider: This is generally the safest and most reliable option. If you have AppleCare+, a battery replacement is free if the capacity is below 80%.
      Otherwise, there is a fee.
    • Third-party repair shops: These can be a more affordable option, but be sure to choose a reputable shop that uses high-quality parts. Using non-original batteries or improperly installing a new one could cause other issues with your phone.”Service” Message: If your iPhone’s battery health screen displays a “Service” message, it’s astrong indication that the battery needs to be replaced to restore full performance and capacity.
