Before updating to 1.0.2, I used to get a battery life of 4 and a half hours of usage and 3 days of standby. After the 1.0.2 update, I am barely seeing 3 hours of usage and 2 days of standby max. I have turned off WiFi network finding, don;t use bluetooth, autolock my phone within a minute, pop emails once an hour automatically, have auto brightness enabled, have disabled my iPod equalizer. Any ideas why this could be happening? Normal usage would be a couple of calls, checking emails, light browsing and iPod usage. Is anyone else facing battery life problems? I searched on the forum and people said that if anything, the battery life seems to have improved

MacBook, iPhone 8 GB, Mac OS X (10.4.10)

    I noticed it seemed a little short as well. Granted I only had my iPhone one day before 1.0.2 so I can't really say if it improved or got worse really, but I did notice it seemed a little short, though at the same time I have been playing with it a good bit since I've had it less than a week.

    I updadted my phone this morning and then went out to work, I had an hour drive I did the usual checking e-mail and stocks every once in a while, I made 2 phone calls and at the end of my ride I was down to 1/2 battery charge remaining. Normally this trip would not have showed any decrease in the battery charge. wifi and blue tooth are off

    So, the update does seem to have reduced the battery life drastically. A lot of people on this forum and elsewhere have reported that WiFi and call volumes seems to have increased after the update. I just hope that Apple hasn't increased the power for the WiFi to get better reception. Less that 4 hours for a phone is a bit of a drag

    Before the update, there was one time I had 12+ hours of using the iPod with over two days standby.

    Now after the update, I get about two days standby with 5 hours mixed usage.

    No change or loss here, i have been playing the iPod all day while at work, Bluetooth & WiFi bothe ON and I still have 2/3 of my battery left. I run it like this everyday and only recharge every other night while I sleep. My record 2 and a half days and it hasn't changed. I use a third of my battery per day.

    Good Luck!

    Have used my iphone just as before with 1.01. Now with 1.02 there is no change of battery time for me. Same usage wifi,email calls etc. Battery life remains the same for me.

    Ok, since I have updated to 1.0.2, I have noticed reduced battery life...

    I do about 2 hours of phone calls per day, and about 4-5 hours of listening to podcasts. Bluetooth ON using a Jawbone, WiFi OFF.

    I used to be able to go 8AM - 6PM, and have 1/3 to 1/2 battery left. Now it is dead by 6PM

    Thanks, Scott K.

    This is interesting. No change in battery life on my iphone. Anyone try a reset, or call apple about this?

    Mine's doing this. I get half the battery life as i did before the update.

    can anyone tell me how to get back to 1.01?

    In 1.0.1 I was getting over 2 days standby and 6-7 hrs of misc. use. Now at 1.0.2 I can barely get 6 hrs of use and recharging every day. I've tried a deep cycle with np change. Currently working my way through a reset to see if it improves.

    Under 1.0.1 my best stats were almost 24hrs standby and 9hrs use but I can't be 100% that I didn't plug in that time.
  • angeldandruff Level 1 Level 1 (40 points)
    I don't think it is possible to go revert back to 1.0.1. I have mailed Apple about the problem and would urge you all to do the same. The link is . Currently, I am getting 4 hours max on my iPhone - compared to 7 hours with 1.0.1

    Ok, here's the fix for shortened battery life... Well, for me anyways.

    I ended up doing a Restore, NOT using my Backup. I tried a Restore using my Backup, and I was still getting shortened battery life.

    Now with a fresh Restore, all seems to be back to normal. Beware, doing a Restore, NOT using your Backup will result in you loosing Notes, Contact Favorites list and YouTube Bookmarks.

    Thanks, Scott K.

    What firmware version does 'Restore' take you to?

    I've posted about my situation on here before, but I have been carefully examining and documenting the situation and here is what's happening to me. I would be interested to see if anyone else is having this exact same problem since the update.

    Prior to the update 1.0.2, I had a perfectly functioning iPhone. The battery charged perfectly and behaved properly.

    Now, after applying the 1.0.2 update, this is what I am seeing.

    If I take my iPhone, with the screen off, and plug it into the dock to charge it, the screen will immediately light up and show the big charging battery graphic. Normally, at the end of the night, I've usually got about 30% left, which is what the graphic shows, BUT about 2 seconds later, the amount that is filled in with green on the graphic will magically JUMP and add an additional 20% or so, making it look like my battery is 50% charged instead of 30%.

    If I leave it like this, then I honestly believe that the iPhone charges until it shows full on the indicator, but THAT is not really full, it's about 20% off. So I wake up to a phone that APPEARS to be fully charged, but is actually about 20% short. This could explain why the battery appears to drain quicker.

    If I put the phone in the dock, let the battery meter magically jump up 20%, then, leaving the phone in the dock, turn it off, and then back on, then the battery meter shows the correct charge (30%) and never jumps back up to where it incorrectly was before I turned it off. If it charges from this point, it still says it's fully charged in the morning, but you can tell that it has received more charge because it takes a lot more use before the battery meter starts dropping.

    So it's been my experience that the 1.0.2 update causes the battery meter to just add about 20% whenever you plug it into the dock. Charging from that point gives you a battery that APPEARS to be fully charged, but is actually lacking about 20%.

    Turning the iPhone off, and then back on, while still in the dock, puts the battery meter back where it is supposed to be and allows your phone to charge from that point.

    I'm curious if anyone else is noticing the exact same thing.

    It kinda' ***** having to turn the phone off and back on every single night, but I guess it's good to reboot electronics on a regular basis anyway.

    Except for this little charging snafu brought about by the 1.0.2 update, I haven't had any more trouble out of my iPhone. I love it! And I hope the next update takes care of this battery meter issue from this update.
