As Android enthusiasts eagerly await the arrival of Android 15, with promises of an iPhone-like battery health section, a nifty trick emerges for those keen on understanding their Android smartphone’s charging speed. By employing the Ampere app, readily available on the Google Play Store, users can gain valuable insights into their device’s charging performance.
Before You Begin: The Essentials
Before diving into the process, ensure your smartphone maintains a minimum 20-percent battery charge for accurate measurements. Use your preferred charging method—be it a wireless charger, adapter + cable, or power bank. The Ampere app, available for free on the Google Play Store, is the key player in this endeavor.
Measuring Charging Speed: A Step-by-Step Guide
- Open the Ampere app, initiating the measurement process that briefly displays “Measuring” on the screen.
- Focus on the central number showcased on the screen; this represents the current charging current in milliamps (mA).
- Additional Information provided by the app includes:
- Minimum and maximum mA: Offering insights into charging current fluctuations.
- Battery voltage: Essential for calculating charging wattage.
- Battery health and temperature: Providing supplementary information.
Calculating Charging in Watt: A Deeper Insight
To gain a comprehensive understanding of charging speed, users can delve into the wattage calculation, considering both current and voltage:
- Note the average charging current in mA from Ampere.
- Record the voltage displayed in Ampere.
- Convert mA to amps by dividing by 1000 (e.g., 2500 mA becomes 2.5 A).
- Multiply the current in amps by the voltage to obtain the wattage (e.g., 2.5 A x 5 V = 12.5 W).
Additional Tip: Verifying Device Capability
After measuring the charging wattage, cross-check your phone and charger’s speed in Volt and Ampere. If your device boasts a faster charging capability than the calculated wattage, investigate potential issues with your charger, cable, or phone settings.
As technology continues to advance, understanding and optimizing charging speeds become essential for users seeking an efficient and reliable smartphone experience.
