yes, with the squelch constantly on. I think the baofeng is 1700mah. if the 250 number is accurate, then Im not really that far off. speaker, light, receiving, 3-4 hours seems reasonable.
I know your not supposed to deep discharge lithiums, but I found a way to do this: drain it until dead, then drop it in the charger for a few seconds, then it will drain some more down. Seems to be helping in increasing my battery life.
Even after a full drain, it is charging way too quickly it seems- nowhere near the 5 hours as the manual describes.
