    Just turn off all location services ,,, bluetooth and wireless off... push off ,,, Install the IOS 5.1 through itunes again,,, but make sure after installing the ios, drain out the battery till circle rolls,,,,, and make it full charge,,, do this charge cycles two times,,, really effective  !!!!!!  (Make sure after updating to IOS 5.1 turn off 3G and celluar data if you don't use it....)

    So I tried the reset on the phone and it didn't seem to work, but I'll admit I was becoming impatient - I only waited an hour or so and it seemed to not have made a difference.

     

    So I sort of took the chicken way out.  I restored to factory settings and a saved image on my hard drive that was about 5 months old.  I then let the phone update to iOS 5.1 again and bring in all my data from the cloud but I lost all text message trails and photos from the last 5 months; I guess they weren't being backed up .

     

    Anyways, it seems better now after reloading the operating system.  No more heat and rapid battery draining.

     

    Seeing as there are over 800 pages of theories, I'll add my own.  The operating system gets corrupted by some unusual event and the symptom is a battery gone wild.  The way to fix it is to reload the operating system.  Nothing else worked for me, but I didn't try them all.  Hope I don't come back here is a few days syaing it happened again.

    Ok this works on my iPhone 4s 64GB improved battery by twice as much or more running on iOS 5.1:

     

    1) Make a backup of your phone to iCloud.

    2) Resetting your phone (i chose to keep data so i didnt have to re-download everything)

    3) Restore your phone from the iCloud backup that you made.

    4) Fully charge your iPhone no matter what battery % it is at.

    5) Let the phone run until it dies for another recharge, fully charge the phone.

     

    My iPhone went from charging twice in one day, to this:

    Usage - 15hrs 8mins

    Standby - 1day 9hrs

    With 34% battery left

     

    And that is running Dell Voice VoIP app in the background at all times running off of wifi (constant drain on battery) I hope this helps if not all at least one other! No official reason behind the fix other than it works.

    Can somebody provide statistics on the average battery life one should reasonably except in terms of active usage with the 4S? Or even better, has somebody come up with a distribution, to which we can relate our own user experience?

     

    Similar to RZGO, I get about 6 hours of active usage and 2 days of standby on average from one full charge. This is after following most advice found on the net on saving energy (e.g. dimming the screen, disabling most location services, manual mails, etc). I run it with Wifi and 3g on but have Wifi access most of the time when using the web.

     

    My gf has a 4 and she gets about a solid 2 hours more of active usage out of her phone. Therefore, in direct comparison, I've been quite dissapointed with the 4s so far.

    And what did you expect?  Basically, if the phone lasts all day under your normal use, you are good.  It is not so much how LONG you use the phone, but WHAT YOU DO when using it.  Each function uses its share of the battery power, and all the functions going on at one time take their piece of the pie.  If you charge each night, then if the battery lasts until the next charge, I fail to see a problem, unless you just want a phone to let sit on a shelf to see how long the battery will last.  Not a very useful way to treat a good phone.

    If you are disappointed with 2 days standby and 6 hours of usage, then I strongly recommend you exchange the phone for a feature phone, or get the RAZR Maxx.

    Current Usage: Battery at 29%

    • Usage: 6 Hours, 18 Mins
    • Standby: 11 Hours, 14 Mins

     

    Should that be a concern?

     

    My biggest battery problem is that is drops significantly on standby. It drops up to 70% over night. However, just the other day, my battery literally went from 88% to 19% in less than 40 minutes, on standby. That has only happened twice.

     

    In reply to the guy above, I don't charge overnight because I like to charge when the battery is below 20%, as recommended.

    Not sure where you read you have to charge when it drops to 20% but this website explains that doing that severly shortens the battery life. Charging overnight is more recommended than letting the battery get that low everytime.

     

    http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batterie s

     

    Here is the important paragraph on that page:

     

    Similar to a mechanical device that wears out faster with heavy use, so also does the depth of discharge (DoD) determine the cycle count. The smaller the depth of discharge, the longer the battery will last. If at all possible, avoid frequent full discharges and charge more often between uses. If full discharges cannot be avoided, try utilizing a larger battery. Partial discharge on Li-ion is fine; there is no memory and the battery does not need periodic full discharge cycles other than to calibrate the fuel gauge on a smart battery.

    I had similar problems when I got my Iphone last week, gone through the settings and found by disconnecting the following really improved things facetime, spotlight unticked everything, Icloud, location wifi and bluetooth dint have to worry bout doing a reset, thin k the biggest culprit was facetime and spotlight

  • germanny Level 1 Level 1 (0 points)

    I am soooooo disappointed with this phone. I have follow every suggestion to get my iPhone 4s's battery to last the day. My iPhone 4 easily handled 10x the work load with plenty of battery to spare.

     

    I have turned off location services, cellular data, Siri, Bluetooth, set all mail to manual fetch, reset all the data on the phone 3-4 times now, removed all my apps that I normally use, added a battery life app to ensure a full charge, and sync nothing more from iCloud than calendar and contacts.

     

    I can make one long phone call, send a couple emails and maybe if I'm lucky I can turn location services back on for a while to use maps.

     

    I do not know why I bought this phone. I have hamstrung it to the point that I could do more on a pay-as-you-go phone (at least I still got text messages - don't get those with cellular data off apparently). I am so so so disappointed and I seriously plan to ask for an exchange back to an iPhone 4, which I loved but cracked the glass when I dropped it. If with cracked glass, it was light years better than this phone.

    What the heck!? I've never seen my battery even come close to these stats! (This was off my last charge)

    To explain the 'iPhone has been plugged in since the last full charge', I had plugged it in for about a minute (Was just going to let it sit plugged in for a while, but decided to run some tests on the battery} the highest I've ever seen my stats get is 5 hours usage, and 22 hours standby at 1%. The only thing I did different than normal was disable all location services. I hope my battery stays like this, because this was absolutely insane!

  • Uncy Herb Level 1 Level 1 (0 points)

    We shouldn't have to turn off all the good things we bought this phone for, just so it lasts longer than 4 hours.

    I wonder what Apple did during Beta testing that made them think this phone has better battery life than previous generations.

    Same thing happened to my phone.  It is sad Apple does not care about these issues.  I received the following advice from a member of this forum, and followed it.  It fixed my phone.  This is it.  Connect to iTunes.  Reset the phone to factory default.  Do NOT restore from your last backup.  It will corrupt the software again.  Then manually add your email accounts, calendar sync, music, etc (as if the phone was brand new). Then add the apps you must have only.  My phone is back to normal....meaning it works for 1/2 a day.

    @ddfromCO: can you please clarify how your stats improved, i.e. state your typical active usage and standby time BEFORE and AFTER the reset to factory default.

     

    That might be helpful for some of us to assess whether it makes sense in our case.

  • germanny Level 1 Level 1 (0 points)

    I visited the Apple Store again today. They could find nothing wrong with the phone, nor did they find it alarming that a phone with nothing enabled - wifi, cellular data, location services, blue tooth, etc - would lose 25% of its charge in 3 hours with no usage (tho the Usage stat showed I had be using it for all 3 hours -  how it is that possible?) and the charge only last 6-7 hours. I was treated brusquely and informed that I was expecting too much, even though I explained I used the iPhone 4 for over 12 hours, running all available bells and whistles. I did receive a new phone, at my insistence, but she repeatedly informed that she could never do this again.

     

    Interesting that System Activity Monitor installed on the old phone only ever showed  "Time to Empty" of 7 hours at best, and this one is showing 10:55 at the worst and up to 18 hours.

     

    But clearly I'm the idiot.

    Xerberus, I did not keep stats.  I am a heavy voice user...upwards of 3000 mins a month.  Prior to my problems, the battery lasted for ~ 4hr of talk time.  This was terrible as compared to by old BB, but I got used to it.  The problem started when I roamed from my home CDMA network to a GSM network in another country.  The talk time was down to 1 hr, and standby time (phone just sitting on my desk) was down to ~2 hrs, even after I returned to the home network.  After the reset, it is better that ever.  As of right now, the phone stats since the last charge is 3hrs 3min usage (mostly voice), 10hrs, 12 min standby.  The batt is at 50%.  I have location services, WIFI, Bluetooth turned on.  However, I have only 3-4 apps installed.  I am scared to install my other apps.
