Galaxy Note 20 Ultra Battery Charging Test: Real-Life Insights

In the world of smartphones, battery life and charging efficiency are hot topics. Today, we’re diving into a real-life battery charging test of the Galaxy Note 20 Ultra. This device has garnered attention for its functionality, and we’re looking to see how it performs under normal usage scenarios. Let’s explore how the Galaxy Note 20 Ultra charges from 20% to 80% using the provided 25-watt charger.

Setting the Stage for the Test

For this test, we decided to start at 20% battery life, a common threshold for many users to consider plugging in their devices. We opted to charge up to 80%, which many feel is a good point to unplug for daily use. The goal here is to provide a real-world perspective, as most users wouldn’t fully drain their phones to 0% before charging.

We’re using the 25-watt Samsung charger that comes included with the Note 20 Ultra, along with a USB Type-C cable. Additionally, to monitor the charging process, we’ll employ the Kavlan USB-C power meter to keep track of the wattage being delivered to the phone during charging.

Initial Power Readings and Charging Performance

Upon initiating the test, we observed a wattage output of 21 to 23 watts, which is consistent with the performance we’ve seen across previous Samsung devices utilizing the same charger. This initial range indicates a robust charging capability when starting from a flat battery.

Breakdown of Charging Times

Every 10% increase in battery charged revealed some interesting results:

• 20% – 30%: Approximately 5 minutes
• 30% – 40%: Another 5 minutes
• 40% – 50%: Around 5 minutes for this interval as well
• 50% – 60%: With a slight increase to about 6 minutes

We noticed the charging speed seems relatively steady from 20% to about 50%. However, when we crossed the 50% mark, there was a noticeable decrease in the charging wattage.

The More the Battery Charges, the Slower it Goes

As the battery level climbed above 50%, the wattage dropped to the range of 14 to 18 watts, often averaging around 18 watts. This drop in power output illustrates a common phenomenon where charging speeds taper off as the battery fills up.

It took around 21 minutes to go from 50% to 60%, which is indicative of this trend; charging tends to slow down as it approaches a fuller state.

A Curious Incident: Wattage Drop-Off

While charging from 60%, we experienced a drop-off in wattage to as low as 4 to 5 watts. Concerned about potential overheating, I touched the back of the device, but it didn’t feel warm. In an attempt to correct what might have been an anomaly, I unplugged and re-plugged the charging cable. Interestingly, this action caused the wattage to bounce back, stabilizing again in the 14 to 18-watt range.

This perplexing incident raises questions about the connection or perhaps a feature designed to optimize battery health. It’s an important observation for users who may encounter similar situations while charging.

Timing the Finish Line: Reaching 80%

After 40 minutes and 46 seconds, our charge meter showed that we had reached the 80% mark. This equates to roughly 41 minutes for a 20% to 80% charge cycle using the standard 25-watt charger. This positive result indicates that for users on the go, a short charging session can provide a significant boost in battery life before heading out.

Full Charge Expectations: 80% to 100%

For those curious about fully charging the Galaxy Note 20 Ultra, it typically takes just over an hour to go from 20% to 100%. This additional time frame provides a helpful guideline if you plan to top off before extended usage, reassuring you of a nearly full battery after a brief but productive charging session.

Final Thoughts

This comprehensive battery testing scenario illustrates the effectiveness of the Galaxy Note 20 Ultra’s charging capabilities. The 25-watt charger provides a very functional experience, particularly in real-world situations. From 20% to 80% in about 41 minutes is impressive and addresses the everyday needs of users looking for quick power boosts.

While the faster charging capabilities of devices like the Note 10 Plus and S20 Ultra may not be fully supported by the 20 Ultra, the efficiency of the 25-watt charger still delivers commendable performance.
