Apple is still working to fix an issue that causes excessive battery drain for some people using iOS 5 on their mobile devices, despite the company issuing an update to remedy the situation on Thursday.
"Upgraded to 5.0.1 this morning. Still draining at the exact same rate. Unplugged with a full charge 2.5 hours ago, and already down to 80 percent with light usage," a user by the name of John Mantooth, wrote on the Apple support forum following the update. "Just lost 2 percent during a 15 minute shower. I see no difference at all."
Apple confirmed on Friday that it was working to resolve the issue for users that were still reporting excessive battery drain while doing relatively little with their handsets.
"The recent iOS software update addressed many of the battery issues that some customers experienced on their iOS 5 devices," the company said in a statement given to AllThingsD on Friday. "We continue to investigate a few remaining issues."
No time frame or confirmation of a second fix was given. Apple had not responded to a request for comment at the time of writing.
Users of iOS 5, primarily those with the new iPhone 4S, began reporting worse than expected battery life performance almost as soon as the handset was launched. Some iPhone 3GS and iPhone 4 users that upgraded to iOS 5 also reported the same problems.
Apple took about a week from acknowledging the issue to sending out the update on 10 November update to remedy the widely publicised battery drain issues in iOS 5. The update also brought security fixes for the platform and gave original iPad owners mutli-tasking functionality for the first time.
