Q: iPhone 4S 5.0.1 Update Improves Battery w/ Settings Reset

After installing the update make sure you reset all setttings. I have done a few updates now  and  have had much better  sucess after settings reset all. Standby drain has been virtually eliminated from 2-4% hr before update. It is located in settings/reset//reset all settings. You loose some wifi and desktop settings, but data, apps, etc remain intact.

sfiomenb,

 

that is probably a good idea. tell them the steps you have gone through. sorry it didn't work out. i am hearing that the are working extremely hard on this and should have annother update shortly that would not require my process. i am not sure that it would fix you issue which maybe the actual battery.  good luck

    Yesterday, I found that going from 100% to 99% took around 3 hours.  Then from 99% to around 80% took another 7 hours.  (That was after resetting all the settings)

     

    This morning, 100% to 99% happened much sooner.

    I decided not to worry about it.  After that, I turned off the Battery Percentage indicator, as I have other things in life to worry about.  No sense in getting preoccupied whenever I turned bluetooth on, or actually used my phone to browse the web.  And, I'll just charge it at the end of the day.

    good plan mistercoffee.  your iPhone is charger fine like it should.  keep the % icon off and enjoy your life!

    Many thanks, davidch!

     

    It works on my iphone 4s too.

     

    After applying the 5.0.1 update I had a large battery drain rate, about 8% overnight. I didn't have any battery problems with ios 5.

    Yesterday I made a reset of all setting on my Iphone and then fully charged the battery. It took a lot of time to charge from 95% to 100%, almost 1 hour, isn't that strange?

     

    This morning I saw that my battery was at 99%! Great!

     

    thanks again

     

    Good to hear this is working for so many!

    I think with normal everyday usage 2 days out of an iphone is about right. Heavy business use maybe a good full day?

    yes... this sounds about right. my goal with all my iPhones (original, 3GS, 4S) was to get a good solid day w/o too much trouble and charge overnight.  before the update and my recommended process it was difficult to do with the 4S and the iOS 5 standby battery drain issue.  now after the update, i am convinced it has the best battery performance of any of my previous models when they were new.

    Does that sound right? Good? Bad?

    this sounds normal to me.  the iOS 5 issue primarily shows up in standby where it drains 2-4% hr or more.  nice to hear from someone across the pound.  enjoy your new iPhone

    Great post and advice davidch. I have read through the thread and tried your advice but unfortunately haven't noticed a huge difference. Right now on the 4S for verizon I have:

    Usage= 2hr 29min

    Standby=17hr 59min

    Battery Left= 58%

     

    This seems kind of ok but I am using it very lightly (light safari, txting, words with friends) and since I have had the 4S phone I can never get the usage over about 4 1/2 to 5 hours.  This is my first iphone and it seems some users on this thread can get 6-9 hours and if I could get in that range I would be extremly satisfied with this over my previous android phones.

     

    I was wondering if doing a "hard reset" would make a difference and if I did one should I let my phone drain down all the way and charge all the way back up before doing one?  Also my phone seems to charge incredibly fast as I can do a full charge in about just over 2 hours.  My old android used to take forever.  Is this pretty normal on the iphones?  Any advice would be very appreciated!  Thanks!

     

    your battery appears normal to me for the usage/standby listed.  however, they do not seem to match your time listed (i.e. 4.5 to 5 hours).  in order for the usage/standby to reset you must drain the phone to 10% or less (i.e. it will turn red).  the 4S recharges very, very fast in my experience.  it is much faster than my previous iPhones or Androids I have worked with.

     

    i recommend you follow my steps from the first few posts of thread carefully.  "reset all settings", go through the setup process (lang, wifi, siri, enable location services, etc), choose "setup as new phone", if provided.  don't worry, your apps, contacts, calendars, mail, data, etc will still be preserved as before.  drain battery completely until the unit shuts off with the spinning icon. recharge the unit fully over night.  good luck!

    Thanks Davidch!

     

    Device: iPhone 4s AT&T 32GB

     

    I had decent 'battery' life before compared to others, got 7 hours of very light usage (mostly iPod and some mail) and 1 day standby and had about 7% left. Having owned a 3GS, I could go 2 days of heavy usage without charging so this was a significant drop with the iPhone 4s. Even worse, overnight I would lose 20% as oppose to 3-5% max with my iPhone 3gs. At the risk of jinxing it, I decided to go do the 5.0.1 update using your advice despite all the warnings from other users. So far I had 88% at the update around 10AM and have 50% left at 4:00PM after extensive use of iPod, emails, surfing, and using the camera. I think this is great. I will update again when I charge the phone and see how the battery acts overnight.

     

    Here are some notes:

    -After the restore as a new iPhone my iPhone couldn't find the network, so I went ahead and reset just the network settings, after that it was fine.

    -The itunes update wouldn't work on my phone, says my device wasn't eligible or something but the OTA did work.

    -Before the update I did cycle my battery twice which I think helps.

    -I only turn on 3g when I need it, turn off location services for most apps.

     

    Hope this helps.

    What do you suggest that I do now? I've reset and fully drained and rechaged my battery... still no changes at all with the battery. Do I need to do a full restore? I really hope not.

    Should I do the reset and discharge again? It'll be the 3rd time.

    sflomenb,

     

    it nevers hurts to do a rest-all and battery re-calibration... maybe 3rd time is a charm ;). i looked back at your stats again and do have pretty good amt usage time. what happens when you leave the phone in standby for several hrs w/o any usage.  Do you get much drain?
