New Delhi: Your iPhone is no longer providing the same battery backup as before? Even after charging 100%, only 20-30% is left till evening? Does the phone suddenly turn off or start running slowly? So there is a 90% chance that the battery life is over. According to Apple, the iPhone's lithium-ion battery is reduced to only 80% capacity after 500 full charge cycles. This means that if you charge it daily, the battery health starts dropping within 1.5-2 years. The best option is to replace the battery if it goes below 80%.

How to check battery health (in 30 seconds)

  • Open Settings
  • Tap on Battery
  • Go to Battery Health and Charging
  • View Maximum Capacity

Above 90% → Perfect

  • 85-89% → Attention, will drop soon
  • 80-84% → Right time to replace
  • Below 80% → replace immediately, Apple itself suggests

What happens when it goes below 80%?

  • phone suddenly shuts down
  • Performance is automatically reduced (Apple's safety feature)
  • Lagging in gaming, video editing
  • Charging speed becomes slow

What are the benefits of battery replacement for iPhones?

  • The speed of the phone becomes like new again
  • Battery backup increases to 8-10 hours
  • Sudden shutdown problem ends
  • The phone lasts for another 2-3 years easily

How much will it cost, and where to get it changed? (2025 rates)

There is a new feature in iOS 19: “Battery Replacement Reminder” which will automatically give a notification at 79%.
