    In that case, I've done that - maybe not as a new user, but I have done it from two different computers which should be pretty much the same thing. Losing my settings in the least of my concerns right now!

    JP sorry but you don't know what you are talking about. Restoring as a new user is very different from restoring from a backup.

    Please restore as a new user and see what happens.

    Also, push is a known battery killer. Can you live with it off?
  • Nathan Goldshlag Level 1 Level 1 (100 points)
    Lani, not everyone has the problem. Battery life has gotten a little better for me.

    Please see my steps above, and get System Activity Monitor.

    Turn push off if you can, it is a known battery killer

    I never said restored from a backup. I said I tried from two different computers - one the one I normally use, the other one with a fresh copy of iTunes that the iPhone has never been sync'ed with. I restored to factory not from a backup. It makes no difference.

    I am aware that push is a battery hog - however I've always had push on from the first day I bought the iPhone and I've always gotten a day or more of battery life. This has only started as of 3.1.3. No, I cannot live with it off.
  • Lani Shuck Level 1 Level 1 (0 points)
    Nathan, I have everything turned off.

    I'm well aware of procedures.

    This came with 3.1.3, as I have never had a problem before. I am getting complaints for a number of people with 3G and 3GS's.

    I never said nor has anyone else stated that EVERYONE is having the problem. But there are enough that are experiencing to believe these people.
  • Lani Shuck Level 1 Level 1 (0 points)
    JP is correct with the previous firmware, and with Push Notifications ON, there was no battery issues.

    This came about with 3.1.3.

    You all can deny this all you want, but it is the truth, it is what is happening in the field on real iPhones.

    That may be true but I don't, millions of others aren't complaining and everyone I know who has an iPhone hasn't got a problem. Methinks you exaggerate to make a point.

    The problem should be reported to Apple to ensure they are not being overlooked.


    Spot on http://www.apple.com/feedback/

    Apple monitors it's discussions.


    No, it only looks at threads marked for duplication, or violation of the Terms of Use, specifically identified by other members. They do not surf the boards as they are too busy and almost never post - the few occasions are easy to spot as there is a little Apple symbol next to their avatar. Good luck finding them !

    My advice to you is to run the battery down and up as I detailed above, and restore as a new user. Use only mail before putting back your apps. If it works ok then, restore your apps. And get System Activity Monitor (SAM).

    Apps and processes can runaway, causing large battery drain. For example, I once noticed larger than usual battery drain and SAM said I was using close to 20% CPU, where it is usually 4-8%. In Safari I deleted the one page that was showing and the CPU usage went down to normal. Something on that page, maybe an animated GIF who knows, was causing constant network activity.

    Apps can use the browser, like Facebook. May be those apps are causing some crap to occur.

    System Activity Monitor is your friend. It will help you see if there is a runaway process.

    Oh yeah? Tell that to the people in the other huge thread who complained about 3.1.2 in the same way.

    I had some battery issues in 3.1.2 and solved them with one or more of the procedures I have detailed. And it got better in 3.1.3.
  • JP@ITS Level 1 Level 1 (0 points)
    Nathan,

    Understand your argument. On the other hand, the sheer logic cannot be argued. I've tried full factory resets on two machines. I can get SAM and take a look. It either identifies something, or it doesn't which just adds to the support of a firmware issue.

    However, interestingly - I just stumbled onto a piece of news relating to Apple blaming Windows 7 on this issue. Both of my machines are Windows 7. There may be something to this. In which case, it may not directly be a firmware issue, but an indirect issue - perhaps even with iTunes or how the firmware is transferred.

    I'd be very interested to know out of the people who have posted in this thread, what OS did you do the upgrade on?

    I just want to update what I said with some real life data:

    Phone was on and at 92%
    Turned the phone off (*)
    Turned the phone on and it was at 87%
    A few seconds later it went to 91%
    Turned the phone off again (it shut down this time)
    Turned the phone on and it was at 84%
    About 10 seconds later it was at 90%.

    So the problem only happens when the phone is first turned on.


    (*) The phone didn't shut down cleanly which happens fairly regularly. When this happens I get a pin prompt at shutdown and then a few seconds later the phone shuts off. When the phone is turned back on, it takes a lot longer and the usage time gets cleared out. Basically it does a reset instead of shutting down.
  • JP@ITS Level 1 Level 1 (0 points)
    System Activity Monitor is showing my phone is running pretty consistent at about 4-6% user, 4% system, sometimes less, sometimes more. But the average is around 8-10% between user and system. To me this shows nothing abnormal is going on.

    3. Reset Network Settings in the Settings app and reboot.

    4. Restore the phone in iTunes.

    5. Restore again in iTunes, and this time set up as a new phone.

    You probably won't need to go beyond 3.

    I too have been having problems with short battery life on my 3GS since I upgraded to 3.1.3.
    I want to thank Lawrence Finch for the suggestion. I just finished this and it seems to work well.

    Think I figured out that is happening.

    3.1.2 status:

    Battery life was bad. Meter goes down pretty quickly with normal usage. Average usage times were like 3hrs at most before I had to plug it into the power socket. Could never charge it to 100%. At most 96%.

    3.1.3 status:

    Noticed that at boot, after a full charge, battery meter is at 96%, after a few seconds, it will correct itself to 100%.
    With the same settings and configuration as my 3.1.2, I had managed to get more than 6hrs worth of usage.

    What I'm suspecting is that the battery meter was adjusted 'higher' such that I will get more usage times than before. Usually at ard 4% or below, the phone will shut down in 3.1.2. Now, because of the adjustment in the battery meter, previously at 4%, now it is at 10-15% after the 'adjustment'. The phone will not shutdown at 10%.
    I did a reboot to confirm this when I was at 10% with 3.1.3. I saw 4% at boot and then it jumped to 10%.

    In summary, with 3.1.2, the phone shuts off at 4% BUT in fact, it still had a lot of power left.
    With the new 3.1.3 battery meter adjusted higher, I can now use it until the battery is really low before it shuts off, thereby extending my usage times.

    Battery life is now fantastic and am comtemplating on selling off my mophie juice pack air

    Hope this helps.

    I have the newer iPhone 3GS 32GB (new boot ROM). Almost wish I had never sold my 3G 16GB a couple weeks ago.

    Here is what I've I've found.

    1. Battery life drains faster even when I turn off 3G and Wifi at night while I'm sleeping. When will the build a scheduler for this anyway? tired of trying to remember to do that. Anyway.. If its around 100% when I got to sleep and in the morning its around 57%. But strangely enough. Last night I forgot to turn off any of it.. so I've had 3G, Wifi, and bluetooth enabled and this morning when i woke up it was about 85%. But funny cause its been saying 85% most of the morning.. Hard to believe.

    2. A couple of my "Smart" play lists have disappeared. Apparently they are too smart for iPhone. I had one playlist that I considered simple. All my favorite hip hop songs with better than 3 stars, random up to 10hrs. Music is there.. but the play list is not.. Not really sure what I'm supposed to do with that. I did a full restore and still nothing. Regular play lists and genius play lists are fine.. This ***** @$$.

    3. Apple is not allowing roll backs any more. Once you are on 3.1.3, you are on 3.1.3. Unless of course you had some previously unlocked or jailbroken version and had an SHSH file. Which I did not. Then you might have a shot at rolling back.

    I'm pretty disappointed.

    << I just found another play list that's just plain empty. The first one just refused to show up at all. In both cases the music is still present somewhere If I look for it by album/artist.>>
