What to Check First
- Energy Saving settings: The battery life shown in the specifications is based on [Maximum Energy Saving] mode. Using a brighter screen setting, such as [Minimum] Energy Saving, will drain the battery faster.
- Battery characteristics: The battery is a consumable component. As it goes through repeated charging and discharging cycles, its performance gradually decreases. It is normal for battery life to be shorter than when the product was new.
- Battery capacity and battery life vary depending on the model and Energy Saving settings.
- Refer to the specifications for your specific model to check the expected battery life.
- The battery life listed in the product specifications is measured using the [Maximum] Energy Saving setting. If you select a brighter screen setting, such as [Minimum] or [Medium] under Energy Saving Step, power consumption increases and battery life may be shorter. This is not a battery defect, but normal operation depending on the selected settings.
- If you need longer battery life, set [Energy Saving Step] to [Maximum]. You can change this setting by going to: [Picture] → [Energy Saving] or [General] → [Energy Saving] → [Energy Saving Step].
