How to Set a 90% Charging Limit for iPhone 17 Pro & Pro Max Battery Health

Setting a Charging Limit on iPhone 17 Pro/Pro Max

• 💡 Open the Settings app on your iPhone 17 Pro or Pro Max.
• 🔋 Navigate to the Battery section.
• ⚙️ Scroll down and select the Charging option.

Configuring the Charge Limit

• 🎯 Here, you can enable and set a custom battery charge limit.
• 📊 Options include setting the limit to 80%, 85%, 90%, or 95%.
• ⚠️ Enabling a specific charge limit will disable Optimized Battery Charging.

Understanding Optimized Battery Charging vs. Charge Limit

• 🧠 Optimized Battery Charging automatically charges to 80% and then waits to finish charging to 100% later.
• ⚡ Setting a charge limit, however, will stop charging at the selected percentage (e.g., 90%) and not go beyond it.
• ✅ Once you select your desired percentage, save and confirm the settings to apply the charge limit.
