Solution Iphone 4 batter slow charge SOLUTION Just go to settings > reset > 'reset all settings' This is the solution to get the Iphone back to normal (quick) charging!! 100% worked for me after anoying 2 weeks of figuring out WHY it charged sooo slow! You won't lose data/contacts. Only WiFi passwords and some basic settings, but this is not a big deal compare to the slow charge problem! Success!!
