  • Apple Reportedly Working to Remedy Degraded iPhone 4S Battery Life

    one of the most consistent and pervasive user complaints following the release of the iPhone 4S is the seemingly degraded battery life the device delivers on an all too frequent basis.

    According to published reports Friday, the source of this problem is presently unexplainable (except some believe cloud-related glitches are to blame). That's what the folks at UK's The Guardian are hearing. Early today, the Guardian reported that Apple engineers are contacting an unknown number of iPhone 4S owners to try to solve problems with battery life on the new device. Numerous complains have been logged that significantly diminished battery performance is experienced when compared to the longevity and general performance of previous generation iPhones.

    One owner reveals in the story that Apple contacted him directly and requested that he use a "monitoring program" on the iPhone 4S as a first line of defense in simply diagnosing the problem. Here's what the person told the Guardian.

    My battery life was extremely poor - 10% drop in standby every hour. I noticed that the usage figure was roughly half that of standby, even when the phone was not being used, so I assumed something was crashing or running in the background. I switched off all the new features including Siri and location services, but it was still really poor. I also tried setting up a clean phone with no apps but it is still really poor. I then got a call from a senior [Apple] engineer who said he had read my post and was 'reaching out' to users for data and admitted this was an issue (and that they aren't close to finding a fix!) and asked lots of questions about my usage and then asked if he could install the file below and that he would call back the day after to retrieve the info. I extracted the file from my Mac after a sync and emailed it to him. He was incredibly helpful and apologetic in the typical Apple way!
    On Apple's support boards, the iPhone 4S battery life dilemma has been a huge subject of debate, with several theories circulating as to why the degraded battery life is an issue. Several users, interestingly enough, have found that backing up the phone's contents to a computer and then restoring it noticeably improves the battery life of the device.

    Have you experienced disappointment with the iPhone 4S battery so far?

      I don't think it has anything to do with the 4S. I have a iPhone 4 used it on every beta and battery life was fine until 5.0GM. On the public 5.0 battery life is terrible on my iPhone 4, and bad but not as bad on my iPhone 4S. Something in the 5.0GM is causing the battery drain I believe so it should be able to be fixed with an update.

      I have iPhone4 and have noticed a fairly noticeable improvement in battery life since upgrading to ios5, however I did a clean restore to ios5 not an upgrade. I have noticed people that simply upgraded are having weird issues including battery life ones so try a clean restore, set up new phone without restoring backup

      Weird... i never really heard of any battery issues. I thought the media would've made a bigger deal out of this, they love to tear the big companies apart when any issue arises. Removed.

      fortunately there will be a jailbreak for that

      however my 3gs didnt seem to die that fast, and it had some wear and tear on it charging (abusive charging)
      I think your thinking is more along the lines of Nicad.

      I agree with you totally. The data speed, Siri, and better cameras isn't much of a competition for great battery life, mywi, bite SMS, and 600 bucks in my hand. Hmmm..

      Started using iOS 5 when beta 1 hit. Gave up after beta 3. My iPhone 4 would run a marathon on 4.3.3
      Upgraded to iOS 5 and bam, leg cramps...

      5.0 destroys batteries faster on every device I own EXCEPT one. My old bootrom backup 3GS. For some reason,
      the battery lasted quite a bit longer on iOS 5.

      Is this problem on all iPhone 4s, or just some of them?

      Mine was really bad. So I turned off Siri and iCloud and location services off and brightness to 50% and everything seems fine now.

      Edit I turned Siri back on and everything seems fine still.

      Battery life on my iPhone 4 and 3GS is about the same running iOS 5.

      My 4S is on order...hope I don't run into this problem with it.

      Not true, depends on the battery chemistry, in this case, li-poly or li-ion, doesn't suffer from the memory effect(typical of a NiMH battery), also, there is a PMIC inside the phone, you can't overcharge it, the circuitry manages battery charging automatically.

      This complaint isn't new. You get a new phone, you use the hell out of it for the first few weeks. I am sure we all fall into this category. I am not seeing a greatly reduced battery life at all. I just recently (about 2 months ago) went back to iPhone 4 from my EVO and was using it a whole lot. Shortly after the 4S came out, so I am still using it about the same frequency. Battery seems almost identical to me.

      Yea my iPhone 4 blew my 4S out of the water with battery life... I use mine for work too which means through the day I'm taking and making lots of calls with 1 hotmail account and 1 exchange account for mail both on push. I'll take my phone off charge around 8am and it won't even make it to 5pm if I don't have it charging on my desk while I'm not out on the road and I even make a point to now have my car charger connected at all times as I can't afford not to be contactable through the day but it's hardly a "MOBILE" phone anymore.

      Has anyone actually looked at the diagnostic logs that their phone is sending out? Mine has tens of logs every hour, of everyday. And at the bottom of the list it has low memory logs every single day. Tmw as a test I am turning off all diagnostic logs, not sending them to apple, and turning off the location service for it and testing.

      I have a 3gs that at one point was down to 50% in one hour. I stopped everything except icloud with little success. Once i deleted icloud and restarted the phone I was fine. I believe what happens is the phone is continuously copying data in preparation for when you plug it in so it can upload backups to icloud. Zombie Steve Jobs was eating my battery!!

      memory available with icloud and winterboard about 11 mb
      with winterboard no icloud about 120 mb

      The issue is not so much that but the fact that it's constantly checking your location so turn that off in
      Settings->Location Services-> Siri
      I never activated siri in the first place, all activation and notifications are off, no email account set up. my wife took a total of about 20 pictures, and the dang thing shut off. the phone was straight off the charger, and showed full. (not JB)
      when i tried to turn it back on, it showed the red PLUG IN screen.
      WTF apple?
      Now i am starting to understand what the S stands for!
      SHOOT! Empty already?
