iOS 5.0.1 Doesn't Fix the Battery Issue for Many iPhone 4S Users

The newly released iOS 5.0.1 update, appears not to work as advertised and provide a solution for the iPhone 4S battery issue, according to a number of reports (opens in new tab).

Hundreds of users who have flooded Apple forums, are even claiming the contrary - the patch makes the problem worse.

"After update my 4S is the same if not worse," user B737800 complained on Apple's support forum (opens in new tab), adding, "We know now this is definitely a hardware issue. This phone is just not practical for everyday use."

Before the updated version was released to the public, and when it was still in beta stage, some developers, on the other hand, said that the battery drain is significantly lower after the patch was installed.

Whilst the update is still very new it seems unwise to reach to a definitive conclusion about the effectiveness of iOS 5.0.1 in improving battery life.

Other users appreciate the update, with one reader of Wired (opens in new tab) declaring, "frankly, the difference is nothing short of amazing". Apparently he now only needs to change his battery every other day, rather than daily.

However, on Apple's 300+ page support forum thread there would appear to be far more complainers than thankful users (which is maybe not too surprising as it's a support forum). One user was perplexed to find that an hour and a half after he installed iOS 5.0.1, his iPhone battery had drained by 20% without any usage.

Other similar complaints reveal the same issue: the battery problem is even worse than before the upgrade. Moreover, the poor battery performance continues without any WiFi and location services.

It will be interesting to see when, or if, Apple is going to respond to these allegations about the inefficacy of its iOS 5.0.1 update.
