no no wiping only dalvic cache and cache will not wipe data or settings. it only wipes temp files. sometimes these files can pile and and get corrupted. if you get weird bugs, glitches, or bad battery drain then sometimes wiping dalvik cache and cache will fix it. it should always be the first thing you do to trouble shoot.
i would wipe dalvik cache and cache on both phones and see if that helps. but i think your wife's phone sounds more like a new battery is needed.
