Nothing lasts forever—not even iPhone batteries.

Your iOS device is operating on a rechargeable lithium-ion battery. All rechargeable batteries have a limited lifespan. That is why as an iPhone’s battery ages its performance deteriorates.

So when should you actually replace an iPhone’s battery? Read on to find out!

Warning Signs

Here are some of the common signs of an aging iPhone battery:

· Your device loses its charge faster than usual

· Your device takes longer to charge

· When switching between screens, your iPhone freezes for a couple of seconds

· Your device frequently dies when it shouldn’t

Check the Maximum Capacity

Use the following road map:

If you have an iPhone 6 and up, go ahead to Settings > Battery, tap on Battery Health (Beta). The screen will display exactly what the ‘maximum capacity’ of your iPhone is. It indicates the time your device can go between charges—its battery life. This capacity is calculated compared to when your device’s battery was new.

Needless to say, older iPhones display a lower capacity. If the maximum capacity is under 80% of the original capacity, there might be a warning message claiming that you should be alert of possible battery issues in the near future. This isn’t to say that you should instantly replace your iPhone’s battery, but you do need to be wary of possible problems in the functioning of your device.

Unexpected Shutdowns

For iPhone 6, iPhone 6 Plus, iPhone 6s, iPhone 6s Plus, iPhone SE, iPhone 7, and iPhone 7 Plus iOS uses Performance Management for peak performance. 

Right under Battery Health, there is a display of your battery’s peak performance capacity. This indicates if your iPhone’s battery is optimized or not. You should see a message saying, “Your battery is currently supporting normal peak performance”.

In case your iPhone is not able to deliver peak power, you will likely experience a shut down that took you by surprise.  Your device will deliver the message along the lines of “Your device just experienced an unexpected shut down as the battery was unable to deliver peak power. Performance Management was applied to prevent this from re-occurring.”

Once you replace your faulty battery, iPhone performance returns to normal.

Degraded Battery Health

If there is a drastic degradation of your iPhone’s battery then your device will display a message like “Your battery’s health is significantly degraded.”

A new replacement battery is the best option if you face frequent battery and performance issues.
