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.
