Tips for battery usage
Minimizing battery deterioration
The battery is a consumable and the deterioration of its performance and battery life is accelerated under the following conditions.
–
Repeatedly charging the battery
–
Using, charging, or storing the battery in a high-temperature environment
To minimize battery deterioration and ensure longer battery life, keep the following tips in mind.
•
Charge in an environment between 10 °C and 35 °C
If the surrounding temperature is too high or too low, the unit’s indicator flashes in green and orange and the battery cannot be charged temporarily.
•
Avoid charging more than once per day
Charging the battery too often will cause the battery performance to deteriorate. Therefore, the unit will not charge the battery immediately after it is fully charged unless the remaining charge is below 95 % to avoid overcharging.
Maximizing battery operation time
To maximize the battery operation time, keep the following tips in mind.
•
Reduce the screen's power consumption
Reduce power consumption by pressing (power button) to put the unit in sleep mode when not in use, or by reducing the screen's brightness level.
•
Turn off wireless devices when not in use
You can use the action center to easily turn off Wi-Fi, Bluetooth, GPS, and cellular network connections (certain models only). You can also turn on airplane mode to quickly turn off all wireless connections.
•
Reduce the time taken to automatically go into sleep mode
Flick the Start screen to the left, and then in the All apps list, tap [Settings] → [Personalization] → [Lock screen] → [Screen times out after], and select a shorter amount of time taken for the unit to automatically go into sleep mode.
Notes about battery charging time
•
Charging and discharging time varies depending on the unit’s temperature
It takes longer to fully charge the battery in low-temperature environments. The battery also discharges more quickly in low-temperature environments.
•
Charging and discharging time varies depending on the state of the unit
To charge the battery more quickly, turn the screen off.
