iPhone Battery Health 90 Percent, Good or Bad?

As noted before, if your iPhone battery health is at 90%, then it’s still operating efficiently. So there’s no need to replace it for about a year.

The battery health number is just a percentage of the initial maximum capacity of your battery. It may also be a pointer to how your iPhone’s reacting to the battery’s health.

As long as you don’t see the peak performance capability message and there’s no sudden shutting down of your device, the battery’s still intact. It just means that your battery won’t charge to 100% but rather 90%, which doesn’t make a significant difference.

How to Find Out the iPhone Battery Health?

Follow these steps to find out your battery health percentage:

Go to Settings
Choose Battery

Choose Battery Health
Towards the top of the screen, you’ll find the Maximum Capacity section

The number that you see is a percentage of the maximum capacity of your battery. It’s also an indication of how much charge the battery can hold after the current decay. The higher the number, the healthier the battery.

Why Do the iPhone Batteries’ Health Decay?

All phone batteries are considered consumables. Once you start using your iPhone, the battery begins degrading.

Usually, iPhone battery health reaches 80% after 500 charging cycles. However, it might take fewer charging cycles to reach this number if you operate your phone in very hot or cold conditions.

After iPhone battery health reaches 80%, the battery capacity and phone performance will decrease significantly. That’s when your phone begins shutting down randomly, the battery dies faster than expected, and peak performance capability messages appear.

How to Reduce the iPhone Battery’s Decaying Process?

It’s not possible to prevent the decay of your iPhone battery health. However, there are multiple tricks that you can use to reduce decay and prolong the battery life.

Below, you’ll find some easy tips that you can perform:

Never let your iPhone battery discharge to 0%; instead, begin charging when it reaches 20–30%

Never charge the iPhone battery up to 100%, but stop charging when the battery is 80–90%
Don’t operate your iPhone in extreme temperature conditions, either too hot or too cold
Update to the latest software

Use Wi-Fi rather than cellular network data whenever possible
Enable low power mode

When to Replace the iPhone Battery?

You should replace your iPhone battery once its health goes below 80%. It’s estimated to happen after two years of usage. However, the lifetime of your battery differs according to your amount of usage and if you operate your phone in extreme temperature conditions.

Once the battery health hits 79%, your iPhone sends you the following message: “your battery health is significantly degraded.” That’s when you know you have to replace either the battery.

Where to Repair or Replace the iPhone Battery?

If your battery health hits that phase below 80%, there’s still a possibility to fix it rather than replace it. Just book an appointment with any apple store, or maybe go to an officially licensed repair center.

Going to an authentic store or repair center is better than going to any unlicensed shop. This way, you can ensure the safety of your data and the quality of the new battery.

Moreover, this might be a reasonable time to change your phone altogether. This phase could happen after two years of your iPhone usage, so there might be more advanced technologies that have been released into the market.

Pros:

Battery health of 90% is good and can last for up to a year
Easy to check battery health on your iPhone

Can prolong battery life by keeping charge in range of 20-90%
Can repair or replace battery at an official store or repair center

Cons:

Battery health will eventually decay over time

Can’t prevent battery decay
Need to replace battery when it reaches below 80%

Conclusion

If you find your iPhone battery health 90 percent, would it be good or bad? It’s good. That means that your iPhone battery life can withstand at least another year.

However, once your iPhone battery life goes below 80%, it might be time to repair it or replace it entirely. Watch out for when the battery shuts down the phone unexpectedly or when your iPhone sends you messages regarding your battery condition.

To prolong your iPhone battery life, keep its charge in the range of 20–90%. Additionally, enable low power mode and use Wi-Fi instead of cellular network data.
