It really depends on what your longer-term goals and outlook are. Do you need to sell the stock soon or think it's no longer a good investment? Personally I hold onto the call as long as possible, because it won't start decaying as fast until closer to expiration. Also as long as you hold Apple you are getting their dividend, which is an added bonus. If the stock starts moving close to ITM, again depending on your goals, let it get called (then sell puts!) or roll the call out for more premium.
