Owners of Apples’ latest iOS devices (especially 3GS, 4, and 4S iphones) have recently run into some battery life issues. Allyn did some testing and found that the latest iOS 5 operating system has a bug (among others) the phone is not able to enter standby mode thanks to a rogue process keeping the phone awake and wasting battery life. Apple was slated to put out the iOS 5.0.1 update, which was supposed to fix the battery life issues.

Well, the update has been released and many users are still experiencing battery life issues. Apple gave a statement to AllThingsD where it stated that although the recent iOS update addressed many of the battery issues, “we continue to investigate a few remaining issues.” According to this poll, approximately 35% (1,822 participants) are having the same battery issues after the update and nearly 14% are experiencing even worse battery issues than before the update. Conversely, almost 18% (910 participants) of people are getting improved battery life from the update. Lastly, a bit over 33% have not reported not experiencing any battery issues. The poll is currently based on a total of 5,145 respondents.

According to Apple, the battery issues are software related, so here’s hoping that they will get their iphones in a row and release an update to fix the issues. More information on Apple’s statement can be found here. Did the update fix your iphone’s battery woes?
