Best Apps to Check iPhone Battery Health in 2026
Wondering if your iPhone battery is still in good condition? While Apple provides a built-in Battery Health feature, it only shows basic information such as Maximum Capacity and Peak Performance. If you want more details like Battery Cycle Count, Actual Capacity, or Battery Temperature, you'll need a third-party app or desktop software.
In this guide, we've rounded up the best apps and tools to check your iPhone battery health, compare their features, and help you choose the right one.
Why Check Your iPhone Battery Health?
As your iPhone ages, its lithium-ion battery gradually loses capacity. Checking battery health regularly helps you identify battery wear before it starts affecting performance.
- Know if your battery is degrading.
- Check battery cycle count.
- Monitor charging performance.
- Decide when it's time for a battery replacement.
Built-in Battery Health vs Third-Party Apps
The built-in Battery Health feature is sufficient for most users, but third-party tools provide additional information such as:
- Battery Cycle Count
- Actual Battery Capacity
- Design Capacity
- Battery Temperature
- Charging History
