    Phone Battery Health Coach

    Enter your phone's battery health percentage and we will tell you, in plain English, whether it is still in good shape, aging, or due for replacement — plus what it actually costs.

    Step 1: Which phone do you have?

    Where do I find this number?

    iPhone

    1. Open Settings.
    2. Tap "Battery."
    3. Tap "Battery Health & Charging."
    4. Read the "Maximum Capacity" number.

    Samsung Galaxy

    1. Open Settings.
    2. Tap "Battery and device care."
    3. Tap "Diagnostics" → "Battery status."
    4. Read the capacity result.

    Google Pixel

    1. Open Settings.
    2. Tap "Battery."
    3. Tap "Battery Health."

    Pixel 8a and newer show the percentage directly.

    Other Android

    Try a free app like AccuBattery (Google Play). It tracks your battery capacity over a few full charge cycles and shows the result.

    Replacement cost figures are approximate, US-based, and current as of 2026. Apple Store pricing reference: support.apple.com/iphone/repair/service/battery. Apple recommends battery service when capacity drops below 80%.
