Battery longevity issues with the latest iPhone have been linked to a freshly discovered bug with its operating system, as Apple once again finds itself facing an Antennagate-style PR-firefight mere weeks after releasing a new handset.
Problems with the iPhone 4S's battery came to light earlier this week, with some users reporting that they are losing up to ten per cent of its juice every hour when in standby mode.
It had been thought that corrupted contacts being unsuccessfully synced between the new iCloud cloud storage facility and the older MobileME service were causing the problem.
However, today it looks like it could be the location settings that are at the root of the issue.
According to Oliver Haslam of iDownloadblog, a glitch in the iOS 5 operating system means that Apple’s smartie is set to repeatedly verify the time zone it is in.
Haslam states: "Switching it off may mean that your iPhone will no longer set its own time zone when you travel, but that’s a small price to pay for having your iPhone last more than 12 hours on a full charge."
Corroborating his theory is that iPhone 4 owners are reportedly also experiencing reduced battery life since grabbing the iOS platform bump.
News of glitches with the 4S comes after Apple loudly trumpeted the phone’s improved power efficiency at its typically bombastic, all-the-bells-and-whistles launch event.
