ATL always takes the view point of the customer to approach design issues. The following example is on the design of cell phones. ATL test engineers first monitors the current of the phone in different usage modes and the corresponding voltage thresholds of the battery meter. ATL design engineers will then utilize different process to optimize the tradeoffs between capacity and cycle life; discharge plateau and capacity usage and sufficient warning for power cutoff.

Flat Plateau for high cutoff voltage to maximize usable capacity.

Slanted Plateau for low cutoff voltage to avoid sudden cutoff.

ATL has the flexibility to offer a wide range of Plateaus
