In a statement published by Ina Fried of the Wall Street Journal AllThingsD blog, Apple noted, "A small number of customers have reported lower than expected battery life on iOS 5 devices,â adding, âWe have found a few bugs that are affecting battery life and we will release a software update to address those in a few weeks.â
Apple has released an initial beta iOS 5.0.1 build 9a402 to developers to begin testing the new update on iPhone, iPod touch and iPad. The company says the new build "contains improvements and other bug fixes including:
â¢ Fixes bugs affecting battery life
â¢ Adds Multitasking Gestures for original iPad
â¢ Resolves bugs with Documents in the Cloud
â¢ Improves voice recognition for Australian users using dictation
â¢ Contains security improvements
â¢ iOS 5.0.1 beta introduces a new way for developers to specify files that should remain on device, even in low storage situations."
Tracking down battery issues
Since the release of iOS 5 and the new iPhone 4S, specific users have complained about serious battery life issues, although the problems appear to be tied to different settings, carriers, and usage patterns, making the core problems difficult to diagnose and address.
Apple had reportedly been actively investigating the issues with specific users to determine what fixes could be rolled out to general audiences to broadly resolve the problems.
Some users have discovered specific settings that seemed to be actively consuming battery life, including the automatic date and time setting, iTunes Ping, per-app notification settings, and even the "raise to speak" feature in Siri.
Apple's latest iPhone 4S uses a much faster A5 processor with twice the graphics cores and a higher clock speed, but the company notes that average talk time, WiFi browsing and audio and video playback should be roughly the same as the previous A4-based iPhone 4, thanks to new technologies including a slightly larger battery.
Apple has historically released between six to ten free updates for iOS between annual major updates, rolling them out to users rapidly as soon as they are available, making it unique among competing mobile platforms.
