True Dead Battery Mode

True Dead Battery Mode is a mode innovated by LAVA that allows mobile devices, such as tablets or phones, to charge when their batteries are completely drained of power.

Have you noticed that when your mobile device is “dead,” it still has power to tell you the battery is dead?

When a phone or tablet tells you its battery has a 0% charge, it isn’t actually completely dead. However, if you leave this “dead” device out for an extended period of time, it will drain the remaining energy. Then, if you try to charge it through a powered hub or adapter, you won’t be able to as it needs a small amount of power to negotiate a power contract.

Our Solution

True Dead Battery Mode allows a mobile device to charge when its battery is completely drained.

Built into the oSynC-3U OTG , True Dead Battery Mode temporarily cuts off digital communication with the mobile device. It acts as a dedicated charging port so the tablet or phone can get enough of a charge to negotiate a power contract with the adapter and switch into SimulChargeTM mode.

Step One.

If the mobile device does not have enough of a charge to negotiate a power contract, the adapter will automatically switch to True Dead Battery Mode. The MUX USB data lines are shorted so the adapter doesn’t enumerate the adapter’s USB ports, so as not to drain any of the charge coming in.

Step Two.

The adapter will charge the adapter in True Dead Battery Mode for 60 seconds, then it will attempt to negotiate a power contract with the mobile device.

Step Three.

If a power contract is reached, the adapter will switch to SimulCharge™ mode, where the mobile device can simultaneously charge and access the data from the adapter and its peripherals.

If it failed to negotiate a power contract, the adapter will stay in True Dead Battery Mode for additional 60 seconds before attempting it again. This cycle continues until the power contract between the mobile device is successful.
