To turn off Optimized Battery Charging on your iPhone, follow these steps depending on your iPhone model: For iPhone 14 and earlier models:
- Open the Settings app.
- Go to Battery.
- Tap on Battery Health & Charging.
- Find Optimized Battery Charging and toggle it off. The switch will turn gray when disabled.
- You may be prompted to choose between Turn Off Until Tomorrow or Turn Off permanently until you enable it again
For iPhone 15 and newer models (with iOS 16 or later):
- Open Settings.
- Tap Battery.
- Select Charging Optimization.
- Choose None to fully disable Optimized Battery Charging and allow your iPhone to charge to 100% without delay
When you disable this feature, your iPhone will charge to 100% as quickly as possible without waiting to reduce battery aging. Keep in mind that turning off Optimized Battery Charging can increase battery wear over time and reduce its lifespan
. For Macs running macOS, a similar process applies via System Settings > Battery > Battery Health, where you can toggle off Optimized Battery Charging
