Samsung Galaxy Note 20

The Samsung Galaxy Note 20 houses a 4300mAh Li-Ion cell — an adequate capacity that should get most users through a working day, though heavy usage or intensive gaming sessions may require a top-up before evening. Keep in mind that the 6.7" 120Hz display is a significant power consumer — so real-world endurance depends heavily on screen brightness and content type.

Wired charging tops out at 25W (USB Power Delivery). While not the fastest, it keeps charging times reasonable for overnight or desk-charging habits. Specifically, 0-50% takes approximately 30 min minutes, with a full charge completing in around 75 min minutes. Wireless charging at 15W adds the convenience of drop-and-charge, making nightstand charging effortless.

The charging ecosystem extends beyond basic fill-ups: reverse wireless charging at 4.5W for topping up earbuds or a smartwatch; battery health management (Adaptive Charging). The battery health features are particularly noteworthy — they help maintain long-term battery capacity by intelligently managing charge cycles, meaning the Samsung Galaxy Note 20 should hold its charge capacity better over 2-3 years of ownership.

Note that a charger is not included in the box. To achieve the full 25W charging speed, you'll need a compatible USB-C PD adapter, typically costing $20-40 extra. Using a lower-wattage charger will work but charge significantly slower.
