“The recent iOS software update addressed many of the battery issues that some customers experienced on their iOS 5 devices,” Apple said in a statement to AllThingsD. “We continue to investigate a few remaining issues.”
After the update was released Thursday afternoon, many device owners took to Apple's support forums to complain that they were continuing to experience battery issues despite having downloaded the update and having reset their phones.
"Installed the new IOS 5.0.1 two hours ago," one user wrote. "Five percent battery drain in 45 minutes with Wi-Fi and location services turned on and me not touching the iPhone 4S. The new update doesn't seem to help much."
In a poll conducted on Mashable Friday morning, more than 900 respondents (32%) said they were experiencing the same battery performance issues they had suffered before the iOS 5.0.1 update. Another 350 (12%) said performance was even worse. Six hundred respondents (21%) said the update had fixed the problem.
Users started complaining about the battery life of their iPhone 4Ses immediately after they were released. Owners of other iOS devices made similar complaints after upgrading to iOS 5. Apple claimed the problem was a software issue, and the iOS 5.0.1 update was issued to address it.
The recent round of complaints suggests, however, that not all iPhone 4S owners are having software-related problems. Some of the more serious cases -- particularly those that haven't been improved by the iOS 5.0.1. update -- could stem from hardware issues. We'll have to wait for further information from Apple to know for sure.
