Avoid continuous use or storage in high-heat environments. Your device is designed to work in uncomfortable temperatures; however, continuous uncomfortable temperatures degrade battery capacity.
Try to charge the device before the battery level drops to 0%. Charging at greater than 10% can extend battery life up to four times.
Device Maintenance Tips
Power off the device when not in use for extended periods of time. Sleep mode consumes 1.5 to 2% of battery charge per hour. This is required so the device wakes up quickly when the user wants to speak. A fully charged battery will completely drain in 50 to 75 hours of continuous sleep.
Use a conservative auto-sleep setting (for example, 1 to 5 minutes) so the display shuts off when not in use. Sleep mode reduces battery consumption by 75 to 80%.
Reduce the display brightness or use adaptive brightness. Keep the display at a usable but not excessively bright level. A bright display consumes the battery.
Avoid running third-party apps when they are not in use. These apps increase processor demand, which reduces battery charge.
Turn off Wi-Fi when not in use. This also prevents unwanted updates.
Avoid updates while on battery power. Plug the device in to do operating system and software updates.
Perform updates at night and leave the device plugged in for several hours after the update.
Updates often require one or more restarts. It is best to restart while the device is plugged in.
Major operating system updates often consume processor energy for several hours after the update and may wake your device from sleep mode.
Disposing of the Device
If you discard all or part of the device, dispose of all electronic components according to local, state, and/or federal electronic recycling laws.
Customers in Europe need to follow the WEEE and European Battery Directive for details regarding disposal of components.
