    Just drained by battery down to 1% and here are my final stats

     

    Usage :  5 hours 20

     

    Standby: 23 hours 20

     

    Normal right?

    Mostly browsing on wifi I should say, a bit of 3G, odd call, apps etc, the only thing I have turned off is some location stuff.

    Anybody has a battery that can be used for about 8 hrs? my friends' ip4 normally are used abt 7 - 8hr and 1 - 1,5 standby days. Is there any ip4s can do that? i mean even turn off every different & new function compared with ip4. my ip4s can be used for maximum 5hrs. so disappointed.

    Depends on what u did during that 5 hours of use.

    Lets say borwsing the internet, max 10 hours according to apple spec.

    Then 23 hours of standby. I would say 1% per hour (apple spec says 0,5% per hour, but that's without mail)

     

    So 5/10 hours= 50% drain for use

    Then 23% drain for standby = 100-(50+23) = 27%

     

    Again, it all depends on what you've done during the 5 hour use. I would have expexted 27% left with those numbers.

    well, i always have wifi if i need internet, and i think all i did is just playing game, listening to music, and surfing the internet, and turn off almost the new functions such as siri, location service ...

    I've that all but nothing has changed. I'd like use the phone for 1 hour with almost everything off and from 100% it goes to 60%

    Can anyone who have disabled iTunes wifi sync comment on whether or not they have seen a improvement in battery? And how much of an improvement it is ?

  • Smuff47 Calculating status...

    Hi 'ram130',

     

    I thought that iTunes was the cause of my battery problem at the very beginning, but to be fair, I have had a good run lately with battery life after (re) syncing with iTunes since my phone reset.

     

    The last reset seemed to have corrected the problem but this week I have noticed the battery life getting hammered again, which, although I cannot categorically say that it was caused by syncing again with iTunes (not tested over wireless mind you), I have no doubt like most people do that Location Services (LS) reduces the battery life greatly. As I said, almost everyone would know this, but with my iPhone4 running all the same/similar apps and services plus iOS 5.0.1, I never noticed the battery life get drained like it does with my 4S. (I realise the 4S has more CPU/GPU power etc.)

     

    Regardless, I know that the reset -> discharge completely -> recharge to 100% and then reset again (as per 'davidch' suggestion) fixed my phone last time however this time I have decided to only charge my phone to 100% and turn off LS, so I will see how it goes over the next few hours. Depending on the findings I will move on to my mail accounts as these were the only non-standed configuration (if you could say it that way) I did on my 4S after reset, which include enabling LS but disabling iCloud and Siri during the initial start up.

     

    Aside from this, I am clutching at straws and hoping the reset procedure helps the phone settle down again.

     

    Cheers.

    ram130, I have done so after your initial post regarding it. I have seen an improvement. Cant say for certain how much because the phone is used differently each day but  the first day I did it I actually ran for 2 days before charging (low usasge ) but I have never gone to bed without putting it on the charger. So i thought I would try since I wanted to see just how long it would go. I was like at 57%  and 1 day standby and 2 hr use after 1st day. Anyway I will say I have seen a definite improvement even if only slightly. The wifi cuts off now when the phone sleeps and you can see it fire up then you first get to your lock screen so maybe thats helping. I typically getting maybe 14-15 hours standby and 2-3 usage and have maybe 60-65% left.

     

    Bottom line: if you can live without wi-fi sync and just plug it in I would definitely turn it off. I dont see it as that huge a benefit although it was cool at first

  • peter3000gt Calculating status...

    I have now used it for a few days since the last reset,. and I also deleted some apps. And the battery has acctualy improved. Now I can use it the complete day,. most times

     

    But lets not be to happy. its still too bad for a phone in this class. But still im alittle happier

     

    Thanks for your help again

    Excellent news!  I assume you did the battery calibration as well? The entire process is required for optimal success. Also if you  can do without wi-fi sync with iTunes, turn that off. You probably have to go to the machine anyway unless u leave iTunes open all the time.  And set mail to manual. I mean unless you HAVE to have your mail sitting there waiting for you to look at,  it makes since to just have it load when you  open your mail application to actually read it. Its fast and that will further save your battery verses it downloading mail every x min. Lastly have some positive reports that 5.1 is helping too (of course some say no) but still hope yet.

    i dont know if this technique will work permanently - but on the 2nd time i tried it (first time didnt seem to do anything) - im at 1 hour 4 minutes usage  over 6 hours standby and the battery is at 90% - hopefully this fix will make the improvement permanent - before the i tried the fix (the 2nd time) - 90% battery was good standby time but usally around 30 minutes of usage

  • owh786 Calculating status...

    what technique are you talking about?

    My usage has been excellent so far after the posted thread to reset all settings:

     

    Usage: 50 minutes

    Standby: 18 hours, 57 minutes

    and 87% remaining!!!!!

     

    BTW, I have wifi and 3G always off unless i really need them!!!
