Ever since Apple released iOS 4.3, many iPhone users have been reporting a noticeable decrease in battery life from iOS 4.2.1. While further releases tend to help battery life a little bit, users state that their iPhone battery life still doesn’t last as long as it did on iOS 4.2.1 and earlier.

Apple released iOS 4.3.3 earlier this week, and in addition to rectifying the infamous location tracking bug, the update was also supposed to bring battery life improvements. We conducted a similar poll a few days after the release of iOS 4.3.1, and the poll results still showed that iOS 4.3.1 battery life had not improved. 

Now that you’ve had a couple of days to test out the new iOS 4.3.3, we’re curious to know how the battery life has been treating you in the new firmware. While I, myself am still running iOS 4.3.2 (due to the unlock status of my iPhone 4), I plan to test out battery life on the new OS soon.

Additionally, from my own experience, I have noticed battery life isn’t as bad when you restore your iPhone and set it up as as a new device, instead of restoring all your content back. Have you tried this?

But in the meantime, for those of you that already bit the bullet and upgraded to the new firmware tell us how is your battery life? Have you noticed a difference yet, or is your iDevice still suffering from serious battery drain issues?

    Mine is decreased after upgraded to 4.3.3 but a bit (just a bit) better than 4.3.2. The 4.3.1 is the BEST. Hope Apple fix in upcoming release

      i felt like 4.3.2 had a better battery backup than 4.3.1 and 4.3.3. did u notice the other way

  • Bobb

    I felt like the battery backup is reduced than what i had with IOS 4.3.2. I was wondering it it is because i restored to my old backup. Thats not sure. am trying to restore again to IOS4.3.3 and not restoring the old backup.

    I could only say I agree with this “…users state that their iPhone battery life still doesn’t last as long as it did on iOS 4.2.1 and earlier.”. I have a 4.2.1 side by side with my 4.3.1, and how I want my 4.3.1 IP4 battery would last like the 4.2.1. Apple, pls, I know you can fix it. (Note, I got my 2nd IP4 came with 4.3 already, I don’t have a choice to stay on 4.2.1)

    Installing 4.3.3 significantly reduced my 3GS battery-life from ~14hrs to ~7hrs (in 4 hours, consumed ~67%). Turning off location services, and other power-draining features (blue-tooth, wi-fi, etc.) made no meaningful difference. I used to get easily 12hrs of active use (multiple calls, wi-fi surfing, texting, etc.). Any word on a fix?

      Upgrade to 4.3.3 ignificantly reduced my iphone 4 battery-life. Turning off location services, and notifications made no meaningful difference. Next step per Apple Care is a restore.

    The new os improved my battery life in a significant manner

    i am noticing it takes forever to charge my batter like 5 minutes to get 1%…does anyone else have this issue? i just got the iphone 4 yesterday

    I noticed a great improvement in battery life with my iPad. When first updating to 4.0, battery life was destroyed — terrible! I was shutting down all apps at the end of the day, trying every which way to save the battery. It would still drain down overnight. When I upgraded to 4.3.3, I didn’t think about battery life but was starting to question my memory when I saw the same, or nearly the same, battery life left. I began wondering about the upgrade and am just now searching to see if battery life was addressed in this release. I’m still checking my own sanity and the iPad battery life, side-by-side. I’d swear the battery life seems vastly improved.

    My IP4’s battery life is so much worse after the update to 4.3.3… 100% when i went to bed, 7 hours later down to 62%… before it could be at 98% after 7 hours of sleep.. please apple fix this thing, there is nothing more annoying than short battery life.

  • micle69

    My IP4’s battery life is terrible after the update 4.3.3… Never had battery life issues with earlier versions.
    Need to charge my IP4 twice a day, even with ‘normal’ use…. Please Apple get this issue solved asap!!

  • napster

    i upgraded from 4.1 to 4.3.3 two days ago and i was shocked how bad my battery life became i had to google it and that’s what brought me here. in these two days i got a dead battery twice, i never get that for the last 6 months not even one time.. same routine and activities i do before same times and duration of charges.. this 4.3.3 is so bad i already hate it after using it for 2 days only.. i want my 4.1 back

  • svnelvn

    I am still using 4.1 and my friend uses 4.3.2, he always complains about battery life while i never do. i get a good 60% at the end of the day and he needs to recharge his phone at work everyday

    one time we left our iphones in the car for a couple hours, when we checked his iphone dropped around 15% while mine dropped maybe 1-2%. i don’t think i’ll be updating my ios until this issue is resolved

    I finally upgraded my 3gs from 3.1.3 to 4.3.3 and I used to get two days out of my iphone. Now I get 8 hours and I only made a 5 minute phone call! No wifi and no bluetooth… What is going on? I want 3.1.3 back!!!

  • Tin

    Update my 3GS iOS 4.0.1 to 4.3.3 and I see a great improvement on battery life. I don’t know what I did difference from others but I see good thing on my updates. Hope you will too. Cheers!

  • Paul

    Shocking, I updated a couple of days ago.

    Prior to the 4.3.3 update, by 6pm I still have appx 40% and since the 4.3.3 update, I am having to charge it mid to late afternoon, or it goes flat by 6pm.

    I originally restored the phone, thinking it was an app I installed draining the battery, but restoring and leaving all apps off still did not fixed the problem…. Massive disappointment for an update that was to increase battery life!

    If anyone knows how to go back to 4.3.1 or 2, please let me know!!!!

  • Stewy

    ok – I think reading the above the common problem is that 4.3.3 drains the battery in 8 hours with little use.. We have reset the phone several time and the phone seems warm.. All obvious battery consumers are turned off.. Before upgrade the phone was great, after the upgrade the phone needs a hammer taken to it.

    The Update to 4.3.3 has BUGGERED my phone.. Apple you need to fix this mess!!!.

    What are you going to do about it?

    I used to be able to charge my phone after 6pm to go home and now since the the new update 4.3.3 I still have charge and it’s 2:30am, I have approximately 10 percent now and I use the phone alot and it’s working very well, i dont know why people are having problems but I cleared my cache, multi razing is kept at minimum to zero applications open, and wifi was on also but I turned it off after four hours of use, I use the phone all day non stop and alot of gps, I imported my photos 2,000 of them to my computer and now running alot quicker. Very good results

    If you have any problem you can change your phone to a new phone by go to any Apple store retail without any receipt!
