Released yesterday, Apple's iOS 5.0.1 was supposed to resolve a battery drain problem introduced with iOS 5, but some early updaters claim they're running into the same issue. Here are just a few comments among the range of unhappy users: 
 
 "Upgraded to 5.0.1 this morning. Still draining at the exact same rate. Unplugged with a full charge 2 1/2 hours ago, and already down to 80% with light usage." The new update doesn't seem to help much." Some have even claimed that the fix made the situation worse: 
 
 "Lost 15% in 45 mins and I didn't even use the phone. Another Gizmodo user echoes these updates troubles: 
 
 @DurrtyNathaniel: My iPhone hasn't completed a sync since I have upgraded to either of the iOS 5 updates. the battery life was much better, since i updated 5.0.1 for iphone yesterday.  Despite the recent update that was supposed to fix it, the iPhone Batterygate continues: Many users in the Apple Support forums are reporting that the iPhone 4S battery keeps dropping fast and inexplicably.
– The early reviews are in, and Apple's software update to fix the fast-draining battery of the iPhone 4S isn't working for everyone, reports Gizmodo. Sample complaint in the Apple Support forums: "New update is not help at all. I opened Safari and lost 2% just by opening it." Others are reporting new problems, including apps that won't load. "Perhaps Apple's first usage of the over-the-air updating may be bumpier than we expected," writes Jesus Diaz. CNET reports the same. Stay tuned.
