I built ChargeCheck – an Android app to test charging speed and compare cables

Hi everyone!

I recently released my Android app, ChargeCheck, and I'd love to hear your feedback.

I wanted a simple way to compare chargers and USB-C cables without buying additional measuring equipment.

Here's what the app does:

• Run a 60-second charging test

• View estimated battery-side charging power in watts

• Monitor current, voltage, and battery temperature

• Save results and compare different chargers or cables

• Check how stable the measurements are

The app uses Android's battery sensor data, so it cannot measure the exact output of a wall charger. Some phones may not support every measurement.

It's free to download, with ads.

Google Play: https://play.google.com/store/apps/details?id=com.sjcnpjd.chargecheck

I'd especially appreciate feedback from Samsung, Pixel, and Xiaomi users. Do the measurements work correctly on your device?

Thanks for checking it out!
