Why do you need to maintain your iPhone's battery health?

iPhones are everywhere! With billions of iPhones sold over the years, Apple has a large chunk of the smartphone market globally, and for good reason. iPhones are easy to use, offer best-in-class user security and last a long long time. The only issue you could possibly run into is the battery life. Over the years, your iPhone may not last as long as it used to when you first got it. This is because the battery health of your iPhone has degraded and is giving you less output. To understand how that works, keep reading. All iPhones have Lithium-ion batteries. These Lithium-ion batteries tend to age as they are used over time. According to Apple, Battery health basically denotes the iPhone's information about your battery's capacity, peak performance, and whether your battery needs to be serviced. In simple terms, an iPhone with battery health of 90% will require charging sooner as compared to an iPhone with a battery health of >90%, if both iPhones have the same usage and charging times. According to Apple, A normal battery is designed to retain up to 80% of its original capacity at 500 complete charge cycles when operating under normal conditions. It's been 16 years since the first iPhone hit the shelves, surely the batteries would have improved, right? Well, they have improved in some departments, for example, the iPhone 13 Pro Max has the best battery of any smartphone! But at the end of the day, it still has a Lithium-ion battery which ages over time and delivers less mileage down the line.
