Your iPhone battery wears down over time, but Apple includes a smart feature called Optimized Battery Charging to help slow that process. It learns your charging routine and holds the battery at around 80% until you need a full charge — reducing the stress on your battery and improving long-term health.
Here’s how to turn it on:
Enable Optimized Battery Charging on iPhone 14
- Open the Settings app.
- Scroll down and tap Battery.
- Tap Battery Health & Charging.
- Make sure Optimized Battery Charging is turned ON (the switch should be green).
What Does This Feature Do?
Once enabled, your iPhone will analyze your daily charging habits. For example, if you usually charge overnight, it will stop at 80% for most of the night and finish charging just before you wake up. This reduces battery aging caused by staying at 100% charge for long periods.
When Will I Notice the Benefit?
This isn’t something you’ll feel immediately. It’s designed for the long haul — months or even years of daily use. Over time, it helps keep your battery’s health percentage higher than it would be otherwise.
