stamina mode

Stamina mode is a power-saving feature found on some laptops, such as Sony Vaio models with switchable graphics. In stamina mode, the system uses integrated Intel HD Graphics instead of a dedicated NVIDIA GPU to conserve battery life. Users may notice that diagnostic tools like dxdiag only show the Intel graphics card even when stamina mode is active, which is expected behavior. The tag also relates to battery drain issues on mobile devices, where weak signals cause the phone to search for networks aggressively, draining the battery rapidly. In such cases, enabling stamina mode or similar power-saving settings can help extend battery life by reducing background activity and signal searching.
