    Hey guys!

    I'm new to the forum... just want to get some expert advice!

    I've had the 4s (att) (32 gig) for just over 2 months now... battery was great for first 7 weeks or so... I would leave charged all night, then in morning would unplug. (By the way, is that OK? Or should I unplug as soon as it gets to 100%??)

    Anyway, the batter would still be over 50% the next night, so some nights I would not even charge!

    I was happy!

    (bluetooth off, several location services off, email on fetch, etc.)

     

    THEN about a week ago it was like a switch flipped!

    Battery losing charge by 5PM or so!

    I even did a test one evening: charged to 100%, turned off all apps, switched to airplane mode, went to sleep... In the morning it was down to 70%

    ???

    What the heck?

    The only things I could think of that I had done differently were: Add several videos from my itunes library (about 12 gig)

    And the other thing I did about the same time was download a book reading app from my library! (Reads audio books out loud.)

     

    But would those still account for the 100 down to 70% overnight with all apps quit and airplane mode?

     

    So I just tryed RESTORE and SET UP as NEW Iphone... then I ran iphone down to 0%... Now I'm charging back to full. We will see what happens tomorrow...

     

    What do you guys think?

    A: (Charging: Unplug when charged to 100% or simply unplug when I wake up in the morning or when convenient?  Or does it matter?)

    B: Is my battery bad?

    C: Did I do the right thing with restore?

    D: Should I take it to the Apple store Genius bar?

     

    sorry for the long post guys!

    If anyone has time to comment, that would be great!!

    Thanks!!

    :-)

    A: It doesn't matter, just leave it charging overnight while you sleep/do other things.

    B: Possibly. Mine used to drop 50+% when in flight mode with no apps running.

    C: Yes

    D: Yes

    This is really easy. Double-tap the home-screen button, then keep your finger on one of the icons until they go into "wiggly" mode. Delete all the icons there. They are applications that are sort of running in the background and use LOTS of battery when you keep them there. Also, turn off 3G if you're not using it, its a major burner. If you close all your apps doing the double-tap thing, the iPhone hardly loses 5% during an entire night.

     

    That SHOULD work.

    The usefull way could be a Connection Scheduler iOS integrated:

     

    WeekDays Schedul:

     

    · WiFi Always enabled ·

     

    08am to 10am: Enable  3G

    10am to 02pm: Disable 3G - WiFi Connected

    02am to 08pm: Enable  3G

    09pm to 08am: Disable 3G - WiFi Connected

    No it won't. When charging is complete, the battery is removed from the circuit.

    Just to add my input, just got a 64 gig 4S and did a check.

    AT&T phone fully charged before I went to bed.  The

    only "running apps" were the phone and iMessage.  Bluetooth

    and WIFI disabled.  Cellular data was enabled (operating on 4G).

     

    Overnight for about 9 hours idle under tis condition, battery level

    dropped to 95%.  After about 1/2 an hour of 4G network use

    (checking accuweather and radar, some App Staore browsing,

    and some news browsing), charge level dropped to 92%.

     

    One thing that will really chew up battery is GPS.  If any app

    that does very periodic polling with location services will chew up

    battery.  If it is constantly getting location (like using the bi.cycle

    app) and WIFI, Bluetooth, and Celllular data off, it will chew up

    about 10% every 30-45 miniutes or so.

     

    Actually, compared to my old LG Thrive Android GoPhone, the

    new iPhone 4S seems like an energy miser.

    Try shutting off all running apps by double clicking home button, then pressing icon until a minus sign appears, press the minus sign and that shuts off running programs.  Discovered today, you even need to shut down the phone app.

    Charging overnight with the charger provided by Apple is definitely OK.  Other chargers, may be less than good for the phone.  My wife has been charging her 3GS for about a year and a half from her computer USB and the battery still last all day unless she is doing something really intensive.

    Wrong, Mr. Wong (sorry, I couldn't resist).  It will do no harm to the battery to leave it on the apple charger overnight.  When the battery reached the programmed voltage, the charger cuts it off.

    Maybe is correct, Yes is correct, and 'only if the battery is not satisfactory after what you have done.

    Hi, guys! Please, tell me. Is it normal? Just played "Cut the rope" for about an hour and my full battery went down to 50%. Bluetooth is off, wi-fi is off, GPS is off. Everything seems to be OFF... except 3G (no notifications, push and so on). It's kinda disaster...(((( If I don't play games the battery loses almost 1% in about 5-10 minutes (it depends)... even if I turn off 3G...
