SimulCharge Mode
The nLTS products place a Lenovo mobile device into the SimulCharge Mode. SimulCharge
Mode informs the mobile device to operate as a USB Host controller, but not to provide power
for USB accessories. With SimulCharge mode active, the mobile device is expecting power to be
provided to it for battery charging and running the mobile device. This allows the mobile device
to be run while simultaneously interacting with one or more USB accessories. The SimulCharge
charging rates are specific to each mobile device.
Lenovo mobile devices operating in SimulCharge mode may limit the amount of power drawn
from the external power source. Limiting the power drawn from the external supply allows the
supply to be shared between the mobile device and USB accessories. If there is not enough
power coming in, the mobile device takes the extra from the battery. Therefore, in this case the
battery will not be charging. The screen brightness may have to operate at less than 100% to
allow the battery to charge. The color scheme of the device application can be designed to reduce
the power required. Application processes requesting too much CPU time increase the power
needed for the mobile device.
The nLTS products use features specific to a set of Lenovo mobile devices which are identified
in the System Requirements section. Simultaneous battery charging and USB Host operation are
not universal among Lenovo mobile devices. Mobile device models have different features
based on country/region.
The nLTS products must always be powered to keep the mobile device charged, and allow
operation with USB accessories.
