The impact of phone cases are usually when you leave the case on the phone while charging since the phone heats up that way..

No need to worry a lot about battery health Hindi naman po mahal mag pa papalit mismo sa store na authorized by apple at worth it na original battery Ang ipapalit at di ka matatakot kasi sa store talaga authorized

i removed the case when charging. its kinda hassle at first but got used to it now. also not using data all the time. i mean if may wifi, better pero if wala na on lang ang data if needed. may android phone ako, nakiki hotspot nalang ung ip ko 😂
