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
- Open Settings.
- Tap "Battery."
- Tap "Battery Health & Charging."
- Read the "Maximum Capacity" number.
Samsung Galaxy
- Open Settings.
- Tap "Battery and device care."
- Tap "Diagnostics" → "Battery status."
- Read the capacity result.
Google Pixel
- Open Settings.
- Tap "Battery."
- 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%.
