Hi All, Over last 3 or 4 days my I phone 4S battery has been falling off a cliff Will drain from 100% to nothing in about 4 hours Seems to have co incided with purchasing Navigon but maybe coincidence I have ensured via ap switcher it is not running anything including Navigon Also turned off Navigon in settings, location services. It is also not just a wi fi issue as got message from O2 saying used all my data allowance as well Removed apple podcaster app in case that was downloading all sorts aswell Any thoughts, how do you re set if this may help Many thanks Colin ** To leave the list, click on the immediately-following link:- ** [mailto:access-uk-request@xxxxxxxxxxxxx?subject=unsubscribe] ** If this link doesn't work then send a message to: ** access-uk-request@xxxxxxxxxxxxx ** and in the Subject line type ** unsubscribe ** For other list commands such as vacation mode, click on the ** immediately-following link:- ** [mailto:access-uk-request@xxxxxxxxxxxxx?subject=faq] ** or send a message, to ** access-uk-request@xxxxxxxxxxxxx with the Subject:- faq
