I never remove the battery cover on any device any more than is absolutely neccessary. Frequent removal only starts problems,ie; creaking, breakage, looseness,ill fitting issues etc. Most devices I've owned over the years have had creaking issues crop up sooner or later. I've yet to fail at stopping creaks by inserting a business card cut just slightly smaller than the battery and placed on top of it. Perfect thickness for making it feel solid again.
Side Note: Using the reset hole should be a last resort only when all other options are tried. My $.02
