The charging process for phones and laptops follows a fluctuating power curve, reaching maximum power when the battery is low and the screen is off.

Factors such as battery level, screen status, and temperature protection mechanisms influence the actual charging power. This behavior is consistent, even with the device's original charger.

Normal Power Fluctuation Example: Samsung S24 Ultra

Stage 1: At the start of charging, the initial power output is 41-43W, which lasts for the first 7 minutes.

Stage 2: After the initial phase, the power output stabilizes between 34W and 33W, lasting for 1 hour and 8 minutes.

Stage 3: As the charging nears completion, the power output gradually decreases, with the total charging process taking about 2 hours and 16 minutes.

This gradual reduction in power input is purposefully designed to extend the battery's lifespan.

Recommended Troubleshooting Steps for Suspected Abnormal Charging Speeds:

• Let the charger sit for 5 minutes without being plugged into the outlet and without anything connected to it. This can reset the charger and may resolve the issue.

• Test the charger with a different device and cable to ensure compatibility.

• Try using the charger with different outlets to rule out issues with the power source.
