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.

 Apple rolled out iOS 5.0.1 yesterday in large part to squash a battery drain bug, but some users say their batteries are still losing charge at a fast rate. 
 
 A variety of comments on the Apple Support Forums have so far revealed several people who say the fix did nothing to improve battery life. 
 
 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." 
 
 "Installed the new IOS 5.0.1 two hours ago. I started a test at 1:30 CT today. 5% battery drain in 45 minutes with WIFI and location services turned on and me not touching the Iphone 4S. The new update doesn't seem to help much." 
 
 "I updated last night (UK) and it didn't fix anything. Losing 6% / hr in standby which is the same as with 5.0." 
 
 Some have even claimed that the fix made the situation worse: 
 
 "Lost 15% in 45 mins and I didn't even use the phone. What happened? This update is no help. In fact, it drains the battery even quicker." 
 
 "Updated to 5.0.1 last night and my battery life seems even worse than before! My phone dropped by 4% overnight in flight mode! I have had it out of flight mode since 6.30am (at which time the battery was at 51%), and its now 8.30am and its down to 35%." 
 
 "For me, its worse than ever. the battery life was much better, since i updated 5.0.1 for iphone yesterday. Battery % was on 92% last night, 3g is not on, wifi also, and now the battery is on 69%. unbelievable!!!" 
 
 In the midst of the complaints, one user chimed in with a more reasoned approach: "Don't rely on immediate numbers when you've had mixed pre/post patch usage. Most likely you need to reset the network/device itself and discharge/recharge! It's not magic! Enthusiasm is normal but Apple users have to learn to be methodical." 
 
 In line with that, some people advised performing a total discharge to 0 percent and then recharging all the way. Others suggested resetting the device by doing a complete backup and restore. 
 
 Apple also provides a page on battery usage for the iPhone and how it runs battery tests on the various models. 
 
 The users who say iOS 5.0.1 didn't resolve the battery problem could be in the minority since other early adopters reported that the update did, in fact, take care of the issue. And several people on the Apple Support Forum say the fix did help them. But even a small minority can indicate that the update didn't fully address the issue or that other factors may be involved. 
 
 Complaints of poor battery life certainly didn't start with the iPhone 4S or iOS 5. Users of the iPhone 3G also griped about short battery life. Older versions of iOS, or the iPhone OS, such as OS 1.1.3 and OS 2.1 triggered grumblings over the same issue. 
 
 But complaints seem to be on the rise. Today's crop of smartphones run a variety of apps and services, often in the background, all of which can easily chew up battery life. In the case of iOS 5, many users have already tried disabling notifications, turning off location services, and tweaking other features, yet the battery glitch seems to persist for a fair number. 
 
 In a statement provided to All Things Digital, Apple said, "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." 
 
 Update, November 11, 12:03 PT: adds Apple statement. ||||| 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. But there are other problems too. 
 
 Updated: We've added new reports to the article. Please keep posting them in the comments. 
 
 Users who were experiencing the inexplicable battery drainage are still seeing the same problems. There are multiple reports in the Apple Support forums. Here are some. 
 
 New update is not help at all. I opened Safari and lost 2% just by opening it. 
 
 Upgraded to 5.0.1 this morning. Still draining at the exact same rate. [...] I see no difference at all. 
 
 Same here. Updated about 1.5 hours ago, battery has drained 20% since then with no usage! 
 
 Gizmodo readers are reporting similar problems: 
 
 @IamRickB: my battery has drained 40%/2hr 
 
 @unsulk: I stand corrected. My 4S battery is draining 1% every 3-4 mins under light use. It was fine before the 5.0.1 update. 
 
 The same reader later added in another tweet: 
 
 The battery dropped from 100% to 89% without ANY use on my 45 minute drive to work. 
 
 Meanwhile, other users are experiencing problems downloading applications over the air with iOS 5.0.1: 
 
 Wow, can't even download apps OTA on iOS 5.0.1...apple just committed a major #chansefail anyone else having this issue? 
 
 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. It's so annoying. 
 
 Another Gizmodo reader confirms the battery issues plus a couple others: 
 
 @gemmasolutions: Battery issue persists with 4S iOS 5.01. Since update, have a problem with apps not sending (iMessage) or loading (App Store) data! 
 
 It seems that something is definitely wrong with this update. Too many reports of users having battery problems. Perhaps Apple's first usage of the over-the-air updating may be bumpier than we expected. 
 
 Definitely, the iPhone battery drainage seems to be a problem still. Are you experiencing the same problems? Do you have other problems? Tell us in the comments. [Apple Support via 9to5]
– 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.
