🗓️ October 10, 2023 By ✍️ Jaysukh patel

The iPhone 15 series is officially out now includes several updates, such as a new Action Button, USB-C port, Titanium Frame, and more. However, Apple didn’t release any battery-related updates during its launch; there is a nifty new aspect tagged as “80% Charging Limit” on the latest iPhone flagship to extend battery life. 

Having poor battery performance of older iPhone flagships, many users found that capping the charge to 80% can enhance overall battery health. The idea that constantly charging your flagship to the max might compromise the Battery’s health over time. Thus, enabling the 80% charging limit on iPhone will juice up to 80% instead of the full 100%. For this, read our article.

Enable charging limit & Increase Battery Life

Before moving forward with the procedure, let’s look at the benefits of turning on 80% charging limit on the iPhone 15.

Benefits of the 80% charging limit on your iPhone 15

  • Battery health preservation: Limiting the iPhone battery health to 80% will extend the battery life span. Lithium-ion battery tends to degrade rapidly, and one of the common reason for the degradation of battery health is consistently charging to 100%. By limiting the charge to 80% will affect battery health more slowly. 
  • Reduced heat generation: Juicing up your iPhone to maximum capacity produces more heat and accelerates battery degradation. By configuring an 80% charging limit, there is a chance of less heat during the charging cycle, potentially decreasing wear and tear on the battery. 
  • Enhanced Safety: Limiting charging to 80% decreases the risk of overcharging, which can result in battery swelling.
  • Improved Energy efficiency: Charging the iPhone to a lower capacity means less energy is consumed during the charging cycle.
