About Optimized Battery Charging on your Apple Watch - Apple Support? ›

This feature, called Optimized Battery Charging, is designed to reduce the wear on your battery and improve its lifespan by reducing the time your Apple Watch spends fully charged. Optimized Battery Charging is on by default when you set up your Apple Watch or after updating to watchOS 7 or later.

To reduce battery aging, Apple Watch uses on-device machine learning to learn your daily charging routines so it can wait to finish charging past 80 percent until you need to use it. Open the Settings app on your Apple Watch. Tap Battery, then tap Battery Health.

All Apple devices use lithium batteries which control their charging to shut off when the battery is fully charged. Your iPhone and Apple Watch will not be damaged by charging at any battery state, and a full top-up ensures you begin the next day with maximum readiness and battery duration.

In macOS Big Sur or later, Optimized Battery Charging is designed to improve the lifespan of your battery and reduce the time your Mac spends fully charged. When the feature is enabled, your Mac will delay charging past 80% in certain situations.

Turning off charging optimizations can increase wear on your battery and reduce its lifespan.

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%.

It is true that not charging your battery past 80% or letting it drain to 0% all the time can extend its lifespan. It is the constant charge and discharge of electricity that wears batteries down over time.

The battery technology used in Apple Watches is designed to handle nightly charging without significant negative effects on battery health.

All Apple Watches and iPhones are designed to be charged all night every night on the recommended charger. Unless you are prepared to turn them off for long term storage, "making them last" more than a day actually uses more charge and will shorten battery health.

With watchOS 7 and later, your Apple Watch learns from your daily charging habits to improve the lifespan of your battery. This feature, called Optimized Battery Charging, is designed to reduce the wear on your battery and improve its lifespan by reducing the time your Apple Watch spends fully charged.

What is the disadvantage of optimized battery charging? ›

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.

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.

Introduced in iOS 13, the Optimized Battery Charging feature is a great way to help maximize your battery's capability and improve its lifespan. Optimized Battery Charging does this by using machine learning to understand your usage habits. This includes active using of the phone, idle time, and charging time.

Using optimised battery charging can increase your phone's lifespan, but it may not be beneficial if you have irregular sleep patterns or don't charge your phone overnight. You can easily turn off the feature in your phone's settings.

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%.

If you need to keep certain apps active even when you're not using them, you can turn off battery optimization in these apps. This keeps them running in the background, but may cause them to use more battery power.

But that's not true. According to the "40-80 Rule", lithium-ion batteries, like the ones inside iPhones, work best when they are between 40% and 80% of their capacity. When they are too full or too low, they experience more wear and lose their ability to hold a charge over time.

All AppleCare plans include battery service cover, which means your battery can be replaced at no charge if we test your product and its battery retains less than 80% of its original capacity. AppleCare+ also provides cover for accidental damage from handling, and each incident is subject to a service fee.

Go back to Settings > Battery > Battery Health. Notice there you get a MAXIMUM CAPACITY measurement. If that is over 80 percent, you should be good. Below that, then your battery is getting suspect and you're probably noticing that your Apple Watch no longer holds its charge like it once did.

All Apple Watches and iPhones are designed to be charged all night every night on the recommended charger. Unless you are prepared to turn them off for long term storage, "making them last" more than a day actually uses more charge and will shorten battery health.
