From the internet and the Apple support forum we learn that users experience a battery drain. Does the new iOS 5 operating system use too much power or too many features, using too much power or is it the dual-core processor using more power than a single core? Or is it just a bug? Know that more features mean more use of battery power, while battery improvements haven't kept up yet. And new phones get faster, have fancier screens. And in general, the phone user doesn't know what is really running on their - smart - phones. As long as Apple doesn't come up with a solution to this battery problem, you might try what's indicated next to avoid that battery runs out of power too early. One of the features that might take too much from your battery, is the automatic time zone detection , which can be put off with the Settings app, going to the 'System Services' in 'Location Services' and then way down select 'Setting Time Zone'. Mind apps that use location services, they all use battery-power. Siri does too. ( therefore Android phones have options to show you which apps more heavily use the processor, thus the battery or use a task killer tool to extend battery life) In addition to turning off 'Time Zone' detection, metioned above, you could: - turn off Compass in 'Location Settings', - turn off calendar notifications in the 'Settings' of the Notification Center, - reduce display brightness, - turn off iCloud for Photo Stream and may be more, - disable email push, use fetching and reduce the frequency. You can also turn off automation and get the email only when you want it - at opening the email app. - if you don't use Wi-Fi radio, then turn it off. - turn off 'caps lock key', Some of these recommendations for a longer battery life, apply to most mobile phones. Installing a spare battery isn't an option as it may void your warranty for the iPhone 4S. Some get a phone case with built-in 1500-2000 mAh which adds several hours of runtime. UPDATE on the battery drain: Early 11/11 Apple admits that some faults in the software of the iPhone 4S causes extra battery-power issues. And to be precise there are bugs in iOS 5 operating system. Apple states that it has found some faults in the OS software affecting battery life and that it will be fixed by a software update. The company is now in the testing phase with developers to check effectiveness of the update.
