Apple have officially accepted that there is a battery life issue with their latest version of their mobile operating system. It affect all iPhones from the 3Gs right up the the new 4s. They recently released a new update for iOS5, version 5.0.1 which was hoped would fix the power issues. Some users did report improvements, however most saw no difference and still reported issues.Now Apple are rumoured to be working on version 5.0.2 in another attempt to fox the issue. It was rumoured to be released this week however the rumour mill now claims this will not happen. We suggest that anyone who uses their phone a lot and is running out of power before the end of the day turn of their location services and invest in a spare charger for the office or car.
