Using intelligent machine learning, Apple learns from your habits and takes a step up on helping you preserve the health of your iPhone battery.

Starting inside iOS 13, Apple introduced Optimized Battery Charging that uses intelligent machine learning to improve the longevity and health of your battery. All rechargeable batteries decay over time as they chemically age. What we can do is to prolong that decay so that we can use our devices longer.

What is Optimized Battery Charging

Optimized Battery Charging is available on your iPhone, Apple Watch, and Mac device. The iPads are the only Apple device that has not gotten this feature. We are hoping that iPadOS 15 will change that.

Most of us charge our phones when we go to bed and the idea of having it charged at a 100% for the 8 hours of established sleep you have actually degrades battery life in the long run. Optimized Battery Charging changes all that by maintaining charge of your device to 80% at the middle of your sleep, and waiting until you are almost about to wake up to fully charge your device. Your phone will spend less time at 100% while you’re sleeping, making it safe to leave it charging without harming your battery life. It will also make sure that you have full battery charge by the time you pick up your phone in the morning. It’s a very intelligent way for Apple to learn from your patterns and makes use of that information to extend battery health.

This feature is useful for people who has an established routine. Apple uses machine learning, with the help of the neural engine, and engages only in locations where you spend the most time like at home and work. This feature may not work for those who travels a lot unless Apple establishes that you are practicing the same routine at those locations.

How to Check if Optimized Battery Charging is Enabled

Optimized Battery Charging is enabled by default on your iPhone. You can check that Optimized Battery Charging is turned on by going to Settings > Battery > Battery Health and making sure that Optimized Battery Charging is turned on.

Since iOS processes your established routine at the specific locations like your home or work, location services has to be turned on in order for Optimized Battery Charging to activate. Make sure you have the following turned on.

  • Settings > Privacy > Location Services > Location Services.
  • Settings > Privacy > Location Services > System Services > System Customization.
  • Settings > Privacy > Location Services > System Services > Significant Locations > Significant Locations.

There are times when you are anticipating that you will be going to work meeting earlier than your usual routine. In those instance you can temporarily ask iPhone to speed up charging your device to 100%.

When you see Optimized Battery Charging on your device. You can long press on that notification, or swipe right and click on “Charge Now” to have iPhone to charge it to 100% and temporarily disable the feature. Optimized Battery Charging schedule will continue the next day.

Apple has come a long way by stepping up to make sure our iPhones stay with us longer. It is usually the first to degrade on our phones due to the current limitations of lithium-ion batteries. Looking at the big picture, this feature not only has a positive effect on our batteries but also on our environment.
