All rechargeable batteries eventually need to be replaced. No matter how you maximize your device’s performance and follow best practices for the right handling of rechargeable batteries, they don’t last forever. Batteries are fragile things and require care. Apple knows this, so they designed the iPhone to adjust its performance to the state of the batteries. This good intention backlashed though as people started noticing that old iPhones ran slower than they used to. People sued Apple for intentionally slowing down the old iPhone models to entice people to buy their new models. Apple dismissed this claims and issued a formal statement saying that the reason iPhones are slowing down is due to battery age.

Regardless if Apple is telling the whole truth or not, there is a slice of truth to their statement. Batteries are not forever. All batteries, rechargeable or not, are consumables. Though some require replacement later than others, there will come a time when you need to replace your batteries. But when is the right time to replace iPhone batteries? When can one say that an iPhone’s battery is due for replacement? This article will teach you how to check iPhone battery health and know if it is time to buy a new battery for your device.

A normal battery has at least 80% maximum capacity. If your battery’s maximum capacity drops down below 80%, it is time to consider changing your battery. Aside from the inconvenience of having to charge your device frequently, low battery capacity affects your iPhone’s performance.
Peak Performance Capability shows if your battery can support normal peak performance. When your phone’s battery can support normal peak performance, you will see this message:
Your battery is currently supporting normal peak performance.
If your battery can’t support normal peak performance, performance management is applied to your device. This means that your device may be tweaked to run slower so as to prevent issues and unexpected shutdowns. This is the message that you will see if your iPhone’s performance management is activated:
This iPhone has experienced an unexpected shutdown because the battery was unable to deliver the necessary peak power. Performance management has been applied to help prevent this from happening again. Disable…

Frequently Asked Questions

Q: My iPhone’s Maximum Capacity is now at 79%, but I do not feel that it has degraded significantly. Is there a need for me to change my battery?
A: If there is no issue with performance and your battery last as long as you expect, then you may not need to change your battery yet. However, we suggest that you ready up your funds for your battery and your phone may show signs of slowing anytime soon.

A: As long as your iPhone has no issues other than a failing battery, then changing the battery will improve your iPhone’s performance.

A: The feature is only available to iPhone 6 and later models. Also, your iPhone needs to be on iOS 11.3 to have the feature on your device.
