∞ Apple confirms battery life issues in iOS 5

Since its release, some users have been complaining about battery life issues with iOS 5. Apple on Wednesday confirmed that it has found some issues.

“A small number of customers have reported lower than expected battery life on iOS 5 devices,” an Apple spokesperson told The Loop. “We have found a few bugs that are affecting battery life and we will release a software update to address those in a few weeks.”

There are plenty of battery life saving tips that have hit the Web over the past couple of weeks. Turning off Location Services, Bluetooth, and Wi-Fi are just a few of the tips that have worked for some.

    (too soon?)

    • LOL! Maybe a bit.

    • Concentrate on Flash being a battery hog. Don’t worry if Apple sucks your battery!

        Why worry there is always a fix from Apple. Not like some which has no fix or update. Yes life really sucks for them.

      My battery will sometimes last two days, so if I don’t charge it at night, itll be depleted in the morning!

  • My iPhone 4S still lasts a full day, and iPad 2 still lasts a week on iOS 5.

    • Yeah, mine too. I don’t have any of the issues that have reported around the Web.

    For me the problem seems to have been a simple calibration issue.

    Discharging the phone completely — running the battery down until the device shut itself off — and then fully recharging it has worked wonders. But my battery issue was apparently not as severe as others have experienced.

    • Yes, I did that when I first got it. It’s hard to say if it helped because I never really had issues, but people have reported it did.

    My battery drained in just a few hours of standby. My issue was caused by corrupt calendar syncing. Turning off iCloud syncing, deleting the calendars, and turning on iCloud syncing again fixed my issues.

  • I’ve had the issues, checking Twitter/mail in the morning kills 15% of the battery way faster than it did on the iPhone 4.  But I figured that the complaints would reach critical mass and a fix would be rolled out or I could take it to the genus bar for a replacement.  Apple isn’t perfect but they’re better than any company I can think of for making things right.

  • turning off time zone support and icloud contact syncing fixed it for me

  • My 4S battery life is about 1/2 as good as my old 4 under my common usage patterns (workday, commute, etc). I used to be able to go two days without charging (20% left at the end of the 2nd day), now i can only get one (25% left at the end of the day).

  • I’ve read a number of accounts of corrupted syncing being the cause of rapid battery drain. For me, battery life on my 4S is three to four times as long as on my 3GS.

  • Kris

    I’ve done the discharge cycle and still my battery lasts literally 13 hours between charges.  I’ve been in touch with Apple and my unit is going to one of their iPhone engineering team tomorrow.  Fingers crossed it’ll be a software issue.

  • I don’t think it has to do with iOS 5. They are using a dual-core processor to gain a little bit of speed at the cost of large power consumption.

    • Jarred Sutherland

      Incorrect. Turn your device on airplane mode and see how long the battery lasts even with use. The GSM/CDMA radios are the largest drain on the device.

    thank gawd. I made sure to call before they found a software bug and got them to send me a brand new 4S. yesterday. sucks for them

  • Goop

    Appy, trying to be clever? Ha? “A small nuber of customerrs”! He he he, better aplogise for releasing a hurried device without proper testing.

    • kibbles

      how exactly is 16 months a “hurried” product? do tell.

  • I scarcely use my iPhone throughout the day and it’s practically drained by the end of the day.

    My 4S definitely has issues. Battery drain for a brand new 4S is worse than what I get on my 1 year old iPhone 4 so there’s definitely something going on.

  • JKIndy

    It’s Apple’s way of giving us the full Android experience.

  • darlaj

    This isn’t a 4S thing. The battery on my 4 started to drain at an alarming rate immediately after I installed iOS5. It was fine before. I reported to AppleCare (advised to restore from backup) and a few days later the Genius Bar (advised to wipe and restore from iCloud — which took almost 24 hours). Neither of those helped much. Turning off Photo Stream and Time Zone sync did improve things. I also turned off the Stock Ticker. 

    I’m really looking forward to Apple’s fix, but I certainly feel special being among such a small (but persistent) number of customers..

    My 3G iPad 2 had horrible battery life prior to iOS 5; now it’s better. Go figure. However I also enabled Airplane which was not done prior to iOS5 as I was under the mistaken impression that wifi could not be reactivated with Airplane mode on . I now can get about 6 days worth including on average 1 hour of use the rest on standby.

    I’ve actually been very pleased with my battery life over my 3GS. The 3GS I could count on running down to half or less, depending on usage, over the course of a waking day. My 4S has been much better. Recently got a day and a half with moderate use and Bluetooth turned on.

    I do have iCal syncing turned on, but I really rarely use iCal, so there is rarely (though not never) something to sync. That might be it.

    It’s clear to me that turning off things isn’t the solution. That’s the sort of thing we  make fun of android for, having to turn off services to get acceptable battery life. I haven’t had the battery issues others are reporting, but I will nevertheless be interested in seeing that Apple releases a software fix.

  • I use my iPhone constantly throughout the day and I have iOS 5 installed. Is this just for iPhone 4S? I have the 4 and experience no issues at all. 

  • muruuuuuuuuuuuuu

    My battery will sometimes last two days, so if I don’t charge it at night, itll be depleted in the morning!

  • Debbieindoha

    so is it safe for me to order an unlocked 4s today?  I’m living overseas so the option to just “send it in” for a little fix is nearly impossible.  Do I order or do I wait??? advice please! 🙂

  • Haissamm

    I had update my iphone, but nothing new, same problem with the battery… really disappointed
