so i picked up a used iphone 11 256 gig purple. seller said battery health is 76%. it will cost me around 80$ to get the battery replaced my question is should i just say F it and pay to replace the battery or tough it out for say a few weeks while i save up the money to get it replaced? if it matters when ever im home my iphone is always on the charger and when im out i only use the phone for say my banking or to check the public bus or occasionally text or facebook i dont really game on it unless im home
