80% Charge Limit on the iPhone 15: Can It Extend Your Battery Life?
Apple has been innovating its smartphone technology for more than a decade now. Apart from its design and performance, the iPhone’s battery life has always been a hot topic among gadget enthusiasts.
In iOS 13 and later systems, the iPhone has an Optimized Battery Charging feature that helps improve its battery health. The iPhone 15 now has added a new feature called “80% Limit” that further extends its battery lifespan.
What Is Optimized Battery Charging?
Optimized Battery Charging is a feature that’s available on iOS13 and later. It utilizes machine learning algorithms to recognize your device’s charging habits over time. It tracks when you charge your iPhone and how long it stays plugged in to optimize your battery charging patterns. By learning your daily routine, the feature can slow down battery aging by reducing the time your iPhone spends fully charged.
In the past, leaving your phone charging overnight will hurt your batteries. Instead of immediately charging to 100%, the optimized battery charging will juice up your phone to 80% of its full capacity initially. As morning approaches, the feature will then wait until closer to the time you wake up before topping off your phone 100%.
The purpose of this feature is to prevent unnecessary wear and tear on your battery cells. Frequent exposure to high temperatures and being fully charged can cause permanent damage to your battery, ultimately leading to a shorter battery life. By monitoring your charging habits and adjusting the charging rate, your iPhone’s battery health can be improved.
What Is iPhone 15’s 80% Limit?
In addition to Optimized Battery Charging, the iPhone 15 has introduced a new charging feature called “ 80% Limit” that prevents your device from charging past 80%. This “controversial” addition did suffer complaints at the release of the new phone as most people think that having a full charge is always better.
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.
By limiting your iPhone charge to 80%, you can protect your battery from overheating and overcharging, and reduce the number of charged cycles that the battery goes through.
So, what is the battery’s charge cycle? Each complete charge cycle is regarded as a one-cycle count. As the battery undergoes more charge cycles, the battery’s chemical reaction experiences wear and tear causing a gradual reduction in its overall capacity and performance. According to Apple, a battery under normal use retains up to 80% of its original capacity after 500 complete cycle charges. To put it short, the more cycles your battery completes, the shorter life it becomes. In this case, the 80% Limit is just the right feature to minimize the impact on your battery.
Give Up 20% of Capacity? No Way!
Though using the 80% limit has a significant benefit, it means you have to sacrifice 20% of battery capacity in daily use, probably resulting in a lack of power supply if you are a heavy phone user. So, it seems to be a dilemma between a longer battery life and normal daily battery use.
Fortunately, using charging solutions that can supply timely power for your device is an effective way to have this issue handled.
