    I've done it all.... Its only been doing it a few weeks. I took it to the genius bar and they say nothing is wrong.... I'm at a loss.

    Just today, with only 1 hour of use and 8 hrs 33 mins of standby I'm at 54% battery left.

    I have a question! It´s been a little under a year now that I have my Iphone, and my battery dies within 12 hours! would this be covered by warranty or would I have to pay charges and etc!

    My suggestion is to take the insight posted earlier regarding turning off email services, rebooting and then turning them back on. I also turn of WiFi when I'm not in the area to use it. I also suggest turning off Pushing of email. I have four accounts on mine and use manual fetch instead. There's really no need to check email so many times per day anyway. Just makes people ADD if you ask me.

    My GS battery life has been getting better ever since I got it. Right now I'm at just over 3hrs of use with nearly 10hrs of standby and I'm at 45%. Not awesome, but still better than my first few days with it.

    I also don't mind as much as I do have a Mophie case and can easily bump it to 100% in a very short time.

    Deat lawrence,
    I think you're right and my iPhone has à hardware problem. I'm going to take it to my provider and ask them to fix it.
    Thanks for all of your help!

    Alright, so I finally just went back to the apple store and got a replacement phone. Still same issue with the percentage meter jumping. To replicate turn on battery percentage make note of what it is at, hold top button then slide to power off. Wait a few seconds then power it back up. It will say something lower then what it was before then suddenly jump up. Even the store models did this as well and the "new" one they gave me. It seems the more i charge throughout the day with out completely draining the battery to "recalibrate" the meter, the worse the gap becomes. After a full drain and recharge its only off by about 5% but after a couple days of random charging when I do the steps above the gap is 20% or more.

    Hi Lawrence,
    I think i've solved my problem with my Iphone. After all I've found out that the cause of a heated Iphone and a battery that only last for about 2 a 3 hours was one of my e-mail accounts -> one that is connected to a remote server. Since I've deleated that e-mailaccount my Iphone is working just fine!thanks again for all your helpfull tips.

    Well, you can add me to the flipping list. My battery was down to 40%, I turn the phone off, I turn it back on, and the indicator is in the red with the warning message on the screen. After a couple of seconds, the indicator jumps back up to 40% again.

    Very annoying, to say the least.

    Welp, after another trip to the Apple store I now know what is causing my battery problem...

    I have done everything that has been suggested in this forum and finally Apple replaced my phone... She was working great until I set up my MobileMe on the phone. I set it up and watched the battery continue to drain at an alarming rate...

    That account was the one variable I never considered. My Yahoo push works fine, all the others were set to manual fetch. MobileMe was set to automatic (has it has been since my 1st gen iPhone) and it ***** the battery down.

    I have MobileMe set to Manual now, and my battery is working just fine. Of course, I can't use Find my iPhone now....

    Apple - what have you done to MobileMe? It was working brilliantly and now.....

    I think you had previously stated your CPU usage around 8-10% (pre-fix). Could you post what your CPU usage reports now? Is it the same? I'm trying to figure out whether or not to get the System Activity Monitor app, but will skip it if it doesn't help me identify this issue (I'm assuming it will crop up again from time to time).

    Thanks in advance.
  • Dizzy D Level 1 (25 points)

    Just to be clear, my MobileMe account (which is my only Push account) shows the following options:

    Account Info

    Mail: On/Off
    Contacts: On/Off
    Calendars: On/Off
    Bookmarks: On/Off

    Find My iPhone: On/Off

    From your advice above, I'm assuming you do not recommend deleting the account, but rather flipping those individual switches to "off". In that case, are you saying to only do that for the Mail, Contacts and Calendar portion of MobileMe? Bookmarks and Find My iPhone do not appear under the "Settings -> Mail, Contacts, Calendars -> Fetch New Data -> Advanced" as Push enabled.

    Thanks in advance.

    Dizzy D,

    I used to think that push was the spawn of the Devil. But I really wanted Find My iPhone. So I created a mobile me account and turned everything off except Find My iPhone - note that I don't actually use mobile me for email. As you know, push must be on for that mobile me account for Find My iPhone to work. So push is on, but no apps are using it, and battery life is just fine.

  • Dizzy D Level 1 (25 points)

    Right, but I'm mostly concerned with the best (read: "easiest") way to get the Mail app reset properly to potentially help with battery life. Lawrence has his 5 step process. I'd like to get to step 3. But, I'm just trying to confirm that I only need to switch those settings to Off for Mail, Contact and Calendar in my MobileMe account (and not completely delete the account from the phone and then re-add it between resets).

    Also, I think calling them resets is more accurate (and not "restart" or "reboot"). From Apple's online user's manual:

    "To reset iPhone, press and hold the Sleep/Wake button and the Home button at the same time for at least 10 seconds, until the Apple logo appears."

    Thanks again to you and Lawrence for all of your advice on this thread. I still haven't worked out my battery life problems, but hopefully all will be well soon.

    P.S. I used to seemingly get better battery life by simply resetting the phone every few weeks, but that no longer works. Therefore I'm going to try Lawrence's process. Otherwise, I need to get the 3GS back for an exchange before my 1 year warrantee runs out (in case it really is a bad battery). I've never had this problem on the 3G iPhone (that my wife uses with her push account) or my old 1st Gen iPhone that my daughter now uses in iPod touch-only mode.

    Add one more case to this ongoing saga. I have tried everything that has been suggested. complete wipe and install as a new phone, re-calibrating battery, took it to apple they said, my battery has gone bad, and I would need to pay $199 for a new phone because it was out of warranty (3G). So I took it to an iphone repair shop here in Dallas, and they replaced the battery. Then I went through the reinstall and wipe and new user crap, and still my battery performance *****. It is a little better with the new battery, but still I can barely make it through a day even on standby. I have done all of the push toggling and email account stuff as well.

    So maybe it is a hardware issue???
    Seems WAY to coincidental that the day I upgrade to 3.1.3 my hardware begins failing. On top of that it sounds like many others (not just here on this forum) are experiencing a "hardware" problem. I know some people say they have fixed their problem with turning everything (email account or two, push...) off... I have tried.

    If we go with the simple logic, wouldn't it be the 3.1.3? Which is the thing that changed and triggered everything? Why would I assume that my hardware has failed especially in light of many others who have not found a fix.

    Also while I have tried the removing email account and push notifications, I also feel like that should NOT be a solution. My phone worked a month ago perfectly for two days without a charge with all of these things on... as far as I can tell none of them changed anything; again the only change was the apple upgrade. (I am not a casual Apple Iphone guy, I own an ipad, an iMac, macbook pro, and a powerbook, this is my first complaint with everything I own... not a kneejerk)

    I am not asking Apple for anything free... Just let me downgrade to 3.1.2 or release 3.1.4.
