If the Swift Go 14 empties quickly, find out whether the battery or the software is to blame. Run Windows' battery report from a command prompt to see design capacity against full-charge capacity, and look under Settings, System, Power and battery, Battery usage, for the apps that used the most. The 14-inch 2.8K OLED panel is bright and power-hungry at high brightness, and a 120 Hz refresh rate costs more than 60 Hz. Choose Best power efficiency, lower the brightness, turn on battery saver and check Acer Care Center for battery-care features and BIOS updates.

Exact questions
Common questions
How long should a Swift Go 14 last on battery?+
Acer rates it at many hours for light use, but a bright OLED panel, a 120 Hz refresh rate and heavy apps shorten that.
How do I check battery health in Windows?+
Run powercfg /batteryreport in Command Prompt and compare full-charge capacity with design capacity.
Does the 120 Hz display use more power?+
Yes. Switching to 60 Hz when you are unplugged saves energy.
Should I keep the Swift Go plugged in all the time?+
A modern laptop manages charging, but Acer Care Center may offer a battery-care option that limits charge to extend battery life.
Where do I see which apps use the most power on the Swift Go?+
Open Settings, System, Power and battery, Battery usage. It lists apps by their use over the last 24 hours or week.
