About this app

Find your fastest charger & cable — or see how much power your phone is using when not charging. Battery Charging Speed Tester shows live amps (A), watts (W), voltage (V), and battery temperature with a clean graph so you can compare bricks, cables, and pads in seconds.

• Real-time Amps / Watts / Volts / Temperature
• See power draw even when unplugged
• Simple graph to spot stable rates
• Works with USB-C/USB-A, PD, QC, and many wireless chargers
• Lightweight, offline, no account

How to use: Open the app → plug in (or stay unplugged to view drain) → wait a few seconds for stable numbers → swap hardware and compare.

Notes: Availability and accuracy depend on your device’s hardware and Android battery APIs. Values are estimates for comparison, not lab measurements.

Privacy: No personal data collected.
