SoH indicates how much capacity your battery still has compared to its new condition. An SoH of 90% means the battery still has 90% of its original capacity.

For best results:

• Perform a consumption drive of at least 100 km (60 miles). The longer the distance the better are the results
• Note the SoC before and after the trip
• Record the distance traveled from the onboard computer
• Enter the average consumption
• Optional: Specify additional consumption like A/C or heatpump

Various factors affect measurements: outside temperature, driving style, topography, heating/air conditioning. Take multiple measurements under different conditions for a better average.

The Premium version offers:

• Unlimited vehicles
• Unlimited measurements
• Edit and delete measurements
• SoH history chart with trend line
• PDF export of history

Premium purchases are automatically restored when you're signed in with the same Apple ID. Simply restart the app - the Premium status will be automatically detected.

No. All your data is stored exclusively locally on your device. We have no access to your data and it is not synced with the cloud.

Since data is stored locally, it can be transferred to a new device through an iOS backup. Use iTunes/Finder or iCloud Backup for the transfer.

SoH Checker works with all electric vehicles as long as you have access to the following data from the onboard computer: SoC (State of Charge), distance traveled, and average consumption.

Accuracy depends on the quality of your input data. The more measurements you take under different conditions, the more accurate the average SoH will be. The app uses the same calculation methods as professional battery diagnostic tools.

Try the following:

• Restart the app
• Restart your device
• Check if you have the latest version installed
• Uninstall and reinstall the app

If the problem persists, please contact us.

Make sure that:

• You have recorded at least one measurement
• You have selected a vehicle
• Your iOS version is up to date
