Prevent overcharging

Overcharging occurs when a battery is charged to 100% and kept connected to a charger for long periods. In those conditions, the battery keeps “topping off” instead of resting, which creates heat and stress that can wear the battery out over time. Battery protection keeps your battery healthy by limiting its charge to 80%.

When Battery protection is limiting your charge, you'll see in the status bar.

To maximize battery health and longevity, charge to 100% at least once a week, disconnecting once the battery is full. If you haven’t charged to 100% over seven consecutive days, Battery protection will turn off so that you can.

To turn this feature on or off:

  1. Go to Settings > Battery > Battery protection.
  2. Turn it on .

  3. Adjust settings:

    • To have your phone learn your charging pattern and finish charging from 80% to 100% an hour before you typically unplug it (such as if you regularly charge overnight), choose Smart schedule. Charge at consistent times for five days so that your phone learns your pattern.
    • To always limit charging to 80%, select Manual schedule > settings icon > Always. To fully charge from 80% to 100%, disconnect from the charger and plug it in again.
    • To set a daily schedule to limit charging to 80%, select Manual schedule > settings icon > Specific hours, and drag the start and end times to set the desired duration. Your phone will charge to 80% within the specified time and will charge to 100% outside of the set times. To fully charge from 80% to 100%, disconnect from the charger and plug it in again.
