iOS 6.0.2 Users Report Increased Battery Drain

By - Source: TidBITS | B 21 comments

Problem could be triggered by a chance in WiFi behavior in latest update for mobile OS.

Some iPhone users are complaining of their batteries being drained after applying the latest update, iOS 6.0.2.

A number of users reported the problem on Apple's forums who stress that the new update, which was designed to fix WiFi issues, is draining their batteries faster than before.

One user said: "I can usually get through a day with about 75 percent of my battery power remaining. Today I've gone through 90 percent and I've done nothing special with it."

Another stated: "Today I barely used my phone at all, and I noticed I was down to 40 percent after 3 hours of being off the charger. This is a significant change in battery drain."

A third iOS 6.0.2 updater added: "before with the 6.0.1 I didn't have any kind of problem with the battery, I could have my battery full charged without doing any use of the iPhone 5 the whole night keeping 100 percent. But this morning when I woke up the battery was in 91 percent obviously without using the iPhone during the night."

TidBITS authors Adam Engst and Michael Cohen suggest that the problem is possibly caused by a change in the WiFi behavior in iOS 6.0.2. In particular, the latest update appears to have increased the number of WiFi checks it performs to resolve wireless connection issues.

    Kinda reminds me of AMD's first Phenoms' flaws. Stability or 10% performance hit.

    hence why i'm not updating until a better update is released. Then when my contract is up i'll buy myself the Galaxy S4 (when its released) and deal with the problems with the Android UI. Because every OS on every phone has its own problems. But i'd rather support a company that doesn't try and tear a hole in everyones face.

    "Someone is punishing iOS users for not using better judgement and using Android."

    I would say that but that would be childish and Fandroid-like, so I won't say that. It might be true...but it'd be childish, so I won't say that.

    you mean the bug that only AMD has been able to reproduce and never really cause problemto anyone, me included? One of, if not the mostoverhyped bug in CPU history...

    I have a Iphone 4S for my work phone and noticed that when I went from IOS 5 to 6.01 there was a huge descrease of battery life. Good thing I have not updated it to 6.02 or it would die before I get through half my day

    seems weird, especially the comment "Today I barely used my phone at all, and I noticed I was down to 40 percent after 3 hours of being off the charger. This is a significant change in battery drain."

    the user must either have a failing battery (stupid design if using an internal battery), or something else is wrong.

    I have used both the iphone 4 and 4s and have done battery test where I stream content from a media server until the battery dies and you can easily go 6-7 hours and that is with the wifi constantly being used and the GPU being worked and some minor CPU usage it seems that apple has messed up more than just wifi, they may have also done something that is causing the CPU to either run at a higher load or not scale down, in addition to messing up the wifi, and possibly some messing up of the cellular modem.

    Seriously, they cant even manage just one phone device in their ecosystem right? Just imagine how much effort goes in managing Android for so many devices out there for much lesser profits. Yes Android fragmentation is complex, but I laud Google for the effort and passion that goes into its development.
    Dammit Apple,You had one thing to do!

    You know something is wrong when people with iPhone 4 and 4s say the 6.0.2 update drains their battery faster than before. Wake up people, there is no 6.0.2 for these models so someone is telling porkies!

    Interesting, I'd like to know how the company is "tearing a hole in your face"?

    Unless you mean Google, then I completely understand.
    Advertisers and data collectors are some of the most evil money-milking companies, and Google happens to be both.

    Tell me, has Google ever created anything new, ever?

    Ignorant comment.

    As a dev, I can tell you that if Google is intelligent enough, they have hardly anything to worry about due to vector-based scaling techniques.

    It's Samsung / HTC / Sony / LG / etc who might have a bit more effort in making the OS work for various devices.
    But even still, Android is such a pig of an OS, a huge beast that I believe requests from various handset manufacturers (Android Alliance) have forced Google to pre-package support for most device types out there.

    Not the first time battery drain issues pop up with ios update. They should have learned from past and make better testing before releasing any update.
