Apple Inc. this week released iOS 5.0.1 to select owners in an attempt to fix claims of the iPhone 4S battery drain that has irked consumers.
The new update is said to include a fix for battery life, additional iPad gestures, iCloud document bugs, and new security measures.
In Nov., Apple said it had found a few bugs that were affecting battery life on iOS 5 devices.
A discussion forum at Apple.com claimed the battery life on the iPhone 4S is far less than advertised.
Apple disclaims eight hours of talk time and six hours of internet use via 3G, with standby time of up to 200 hours.
One buyer claimed his iPhone 4S battery life drains at 15 percent per hour while locked and on standby. Another said battery drained 10 percent in 12 to 15 minutes after using iMessage.
Users suspected an issue with location based services, iOS 5, or the new Dual-Core CPU.
The company in Oct. said it sold 4 million iPhone 4S units at launch in the first three days of sale to set a new sales record for the device.
The iPhone 4S began sale at brick and mortar retail stores Oct. 14.
The iPhone 4S includes the A5 Dual-Core CPU, 8MP camera, 1080p HD video recording functionality, iOS 5, and a new voice command protocol called Suri.
Suri can call, text, email, remind, and offer weather, stock, traffic, direction, and definition information via voice commands.
