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?
Down to Business
While I'm mostly a PC guy, I favor iPhones. My friends always jab at me because I'm a fairly die-hard techie, and they expect me to be sporting the latest overclocked super-smartphone with eleventy-thousand gigs and a built-in dishwasher. While my phone used to be included in the list of things I tinker with endlessly, I eventually came to the point where I just wanted my smallest mobile device to 'Just Work' for those tasks I needed it to. I just didn't have the time to tinker endlessly with the thing that handled more and more of my work-related duties, yet as a techie, I still enjoyed the ability to cram a bunch of functionality into my pocket. That led me to the iPhone, which I've used since 2008.
Like many iPhone users, I've upgraded through the various iterations over the years. The original, 3G, 3GS, 4, and most recently the 4S. I've also witnessed nearly every iteration of Apple's iOS (including many of the betas). Throughout all of these, I feel Apple did their best to prevent new versions from breaking application functionality, and while they did their best to keep bugs under control, every so often a few would creep in - typically with cross-compatibility of new features that could only be tested in a limited capacity before being released into the wild.
Apple's iPhone 4S introduced some added features to their line-up - enough to get me to bite the bullet earlier than I typically do. I was a bit of an iOS 5 veteran by then, as I'd been using it to test applications for a developer friend of mine. While some of the iOS 5 betas were a bit unruly in the battery life category, those problems appeared to be sorted out by the last and final beta prior to release. With my reservations against the new OS put to rest, the only thing holding me back was the possibility of the new dual core CPU drawing more power than the iPhone 4. The iFixit teardown (which revealed a higher capacity battery - presumably to counter power draw of the additional CPU), coupled with the improved camera and witnessing the endless toying around with Siri finally got me to bite the bullet.
I picked up a 4S from my local Apple Store, restored from the backup of my 4, and off I went. I enjoyed the phone for a few days, but quickly realized there was some sort of issue with battery life. The most glaring indicator was one night where I forgot to plug the 4S in before bed. The next morning I was surprised to find that nearly 40% of the charge was lost while I slept - almost enough to completely shut down the phone (and failing to wake me with the alarm I'd gleefully set via Siri the night before).
