Our smartphones are getting bigger and better as time is passing on. We are getting bezel-less displays, improved cameras, fast charging speeds. great designs, foldable devices, etc. But one area which in my opinion still needs some attention is the battery. Yes, there are smartphones that house a massive battery up to 5,000 mAh. However, all our devices need charging and probably most of us, keep our devices charging overnight. There have been lots of debates on this, whether leaving devices charging overnight reduces battery life or not. And to overcome this issue, Apple introduced a new feature, Optimized Charging on iOS 13 for iPhone.
With the latest iOS 13, a new feature was added on every iPhone called Optimized Charging. This changes the way your iPhone charges up in order to extend your device’s battery life. Apple iPhone uses lithium-ion batteries that over time, due to a number of charge cycles, degrade. And as the battery degrades, its capacity also degrades. This is probably one of the reasons why Apple introduced the Optimized Charging feature with iOS 13 on iPhones. Let us get more insights into this:

What is the Optimized Charging Feature?
Enabled by default, Optimized Charging feature overtime, learns your daily charging habits like when do you charge your device and how many times you charge your device fully to 100%. Besides, it learns how long your iPhone will need to charge up to 100% overnight. For instance, you leave your device charging overnight, and wake up at 8 AM every day. The Optimized charging feature also learns this daily routine.

In fact, after a few weeks, if you will leave your device for charging overnight, it will charge your device fastly to about 80% and then between 80-100%, your device will charge slowly even it is connected to a charger. Just before 8 AM, your iPhone will then quickly finish charging and by the time you disconnect your device from charging, it will be charged to 100%. This minimizes the amount of time your iPhone spends while at 100% charge, thus extending its battery life. Let us now understand how to enable and disable this feature on your iPhone.
