iPhone 4S users around the world have been complaining about the poor battery life their iPhones are giving. There’s nothing to worry about as the problem does not lie with the hardware, there a big fat bug in iOS 5.x that’s causing this and as it turns out, Apple still hasn’t been able to permanently squash it because many people are still facing battery drain issue on their iPhone 4S, regardless of yesterday’s iOS 5.0.1 firmware update.
Yesterday Apple officially released iOS 5.0.1 firmware update for iPhone, iPad and iPod touch. Obvious from the changelog in the image posted above, this new firmware update was supposed to fix the bug causing battery drain issue particularly on iPhone 4S as well as for select iPhone 4, iPhone 3GS, iPad and iPod touch devices.
While iOS 5.0.1 does bring back multitasking gestures for iPad 1 and better voice recognition for Australian Users, it does not quite fix battery issues being faced by users. Some users have also indicated that their devices started having battery drainage issues after they had installed iOS 5.0.1 firmware update on their devices. It is highly unlikely for something of this sort to happen, though its not entirely impossible.
Previously, when the iPhone 4S battery drain issue got wind, Apple caught hold of it and started working with some end users for finding a fix. Usage data was collected from these users, with their permission of course, in order to find the origin of this bug. As it turns out, Apple has not quite been able to fix this problem in iOS 5.0.1 firmware update, however that does not mean that Apple will not be able to fix it at all. The company has already taken notice of this and has revealed they are working on a fix, in a statement:
The recent iOS software update addressed many of the battery issues that some customers experienced on their iOS 5 devices. We continue to investigate a few remaining issues.
So now there’s a huge possibility that iOS 5.0.2 will be released in the next few weeks because Apple would surely not keep users battling with battery drainage issues. Sources indicate that an iOS 5.0.2 release is possible in the last week of November.
