1. A device comprising a processor configured to:
apply a power back-off (PBO) to limit a radio frequency (RF) transmitter power up to a first limit, wherein the first limit is below a pre-defined RF power limit;
accumulate a difference between RF transmission power spent in transmitting data and the pre-defined RF power limit over a duration to produce an accumulated energy budget; and
in response to the accumulated energy budget reaching a pre-defined energy credit value, remove the PBO and allow RF transmitter power exceeding the pre-defined RF power limit to consume the accumulated energy budget until the accumulated energy budget meets a threshold.
