Battery runtime is low
Problem description: The usage time with a fully charged battery appears too low; the battery runs out quickly.
Possible causes:
- The battery is not initialised correctly.
- The battery is frequently partially discharged.
- Applications or processes are active that constantly require a lot of system performance (and therefore battery capacity).
- The screen brightness is set very high.
- The Windows energy mode is set in such a way that there is a high energy consumption (e.g. maximum performance).
- Peripheral devices are connected that have a high power consumption.
Possible solutions:
- Initialise the battery to restore full capacity: Fully charge the battery when it is switched off, discharge it to 0% and then fully charge it when it is switched off, repeat this process two to three times.
- Check the system for active background processes and programmes and close them if necessary.
- Reduce the screen brightness or use the automatic brightness adjustment function.
- Set the Windows energy mode to a more economical one (‘Balanced’ (balance between performance and power consumption) or ‘Save energy’ (maximum energy saving)).
- Disconnect peripheral devices that are not required or switch them off.
- Disable unnecessary modules in the BIOS (e.g., LTE, LAN, GPS, etc.)
- Disable Intel Speed Step, VT-X, or VT-D if not required (BIOS)
- Disable Wake on LAN S5 Support (BIOS)
Please also note the following information regarding battery life:
Any battery life figures communicated by marketing are to be understood as maximum values achieved in a specific test scenario. Power consumption in the off/standby state is a power management issue that essentially originates from the Intel CPU itself. The new Intel processors remain active even in standby mode and consume power.
The actual battery life depends on factors such as the apps used, the apps open at the same time, the functions used such as GPS, Wi-Fi, LTE or Bluetooth, and, to a not inconsiderable extent, the display brightness.
