What Is Optimized Battery Charging on iPhone? (2024)

FAQs

Is optimized battery charging good for iPhone? ›

With iOS 13 and later, Optimized Battery Charging is designed to reduce the wear on your battery and improve its lifespan by reducing the time your iPhone spends fully charged. When the feature is enabled, your iPhone will delay charging past 80% in certain situations.

When you choose 80% Limit, your iPhone will charge up to about 80 percent and then stop charging. If the battery charge level gets down to 75 percent, charging will resume until your battery charge level reaches about 80 percent again.

Optimized Charge Limit learns from your daily usage to determine when to charge to an optimized limit and when to allow a full charge. Optimized Charge Limit is on by default when you set up your Apple Watch.

It's best to charge it when it goes below 20%, primarily to avoid the risk of it going to zero when you don't have a charger available, and to prevent unexpected shutdowns when you might need the phone.

Cons. Inconvenience:If you have an irregular schedule, or if you often need to charge your phone quickly, Optimized Battery Charging can cause some inconvenience. Because it's designed to finish charging close to when you usually start using your phone, it might not always be fully charged when you need it to be.

I recommend using the optimized option. By limiting my iPhone's battery charge to 80% for two days, I've noticed that not only does my iPhone need to be charged more frequently than before, but the battery life also drops to 99%. Therefore, it's best to stick with the optimized option! "Optimized" means just that.

For optimal battery health, it's recommended to charge your phone between 20% and 80%. It's best to avoid extremes, such as letting the battery reach 0% or consistently charging it to 100%.

A1: Optimized Battery Charging works by learning your charging habits. It stops charging when it reaches 80%, and then completes the rest 20% before you need it. 80% Limit, on the other hand, is a way to restrict charging to a maximum of 80%.

You might think that because your iPhone's maximum capacity begins at 100%, it's the only condition that can be considered optimal. However, that's not quite true. Apple considers any iPhone with a battery capacity of 80% or above to be in optimal condition.

It's important to know about the “80 % rule” if you're on a long-distance drive in an EV. When it's time to charge, it's often smarter to stop at 80% and then get back on the road, instead of waiting for the battery to completely fill up. Doing so maximizes your use of time.

What does optimized charging do? ›

Optimised Charging is a feature found on iPhones and Android phones. It is designed to extend the life of the battery by slowing down the rate of charge when the phone is not in use. Battery life and performance is often one of the deciding factors in a smartphone purchase decision.

You can charge your iPhone every night even if the battery isn't fully depleted. iPhone automatically stops charging when the battery is fully charged, so it's safe to keep your iPhone connected to a charger overnight. Charging resumes automatically if your battery level drops below 95 percent.

Maintain good battery health

It is always recommended by experts to start charging your iPhone when it hits 25 percent. Similarly, only charging the battery up to 85 percent will help the iPhone's battery to maintain good battery health and deliver extended battery life.

If you want to charge your iPhone the old-fashioned way, meaning it will charge up to 100% and continue charging so it stays at 100%, you can just turn off Optimized Battery Charging. I wouldn't recommend turning it off though.

Why should you use it? Using optimised battery charging means that your phone will have a much longer lifespan. There's nothing worse than having a handset that works great but won't hold a charge for more than a few hours, and this feature should help prevent that from happening.

Go to the Battery section and then click on Adaptive preferences. On the next screen that appears, enable the Adaptive charging toggle. Google notes that when the feature is enabled, the battery lifespan of your Pixel device may increase as the phone will steadily charge during longer charging periods.

There are two reasons: charging performance and battery longevity. Most of the time you should only charge an EV to 80% because charging rates slow down dramatically past the 80% mark. And two, the long-term health of your vehicle's battery pack is improved when kept below 100%.

Android™ devices with the Battery optimization setting (Android 8. x and lower) can enhance battery life by placing apps in Doze mode or App Standby. The optimization setting is enabled by default. Disabling optimization may impact the device's battery life.
