The Nintendo Switch 2, while an upgrade from its predecessor with a larger 5,220 mAh battery and a 120Hz refresh rate screen, faces battery life challenges in handheld mode due to its powerful hardware and demanding games like "Cyberpunk 2077." To extend playtime, users can disable the "Handheld Mode Boost," which enhances Switch 1 games but increases power consumption by up to 25%. Additionally, limiting the battery charge to 90% helps preserve the lithium-ion cells' long-term health, and avoiding full discharges to 0% is recommended. Turning on airplane mode conserves battery by disabling Wi-Fi and Bluetooth, and disabling HDR and the 120Hz refresh rate, especially for less demanding games, further reduces power drain. Playing less intensive titles like "Stardew Valley" can significantly extend battery life compared to AAA games, which may only last around two hours in handheld mode.
