    I have also noticed that ANY usage that involves the display being active is a major battery drain...email, texting, games, internet....all using between 10-15% per hour. I don't know what the normal usage should be when the display is on, but that certainly seems to be a bit excessive.

     

    I'd appreciate hearing from some of you more experienced iPhone users as to what kind of battery drain you've seen in earlier iPhones when your display was active.

    I'm having battery issues too.  At first it started with my iPhone running hot.  I went to genius bar twice and they said it's normal since I didn't get the temperature warning.  I did a restore and set it up as a new phone and it' still running hot.  Now after experiencing heat issues, the battery is dying quickly.  This is even with the phone in standby with no apps running.  I had it 100% fully charged and the battery died in about 4 hours.  This battery is worse than the HTC EVO that I had.  It seems I can't get any help.  I strongly believe this iPHone is defective.  None of my other friends who have 4S is having this problem.  I just want to exchange it for another iPhone.

    10-15% battery drain when the phone is actively being used seems normal to me.  You would be getting anywhere from 6.5 hours to 10 hours of active phone use (combination of wi-fi, 3G, mail, etc).

    It's probably not your battery, but something running in the background that continually causes a drain on the batteries (even in standby mode). There are tones of tips within this thread. Or you can figure out what exactly is causing the battery drain in your particular case by diagnosing the problem yourself:

    After looking at the statistics and numbers that people are posting, I feel like there's two distinct groups of people: ones with genuine battery drain that is far from normal, and then another crowd that may be forgetting the official specifications from apple and overreacting...

     

    NORMAL:

    Phone calls - you will lose 12.5% battery life for every 1 hour of calls

    WIFI internet browsing - you will lose 11% of your battery per 1 hour of active continuous browsing

    3G internet browsing - you will lose about 17% of batter for every 1 hour of continuous browsing

    Standby - you will lose 0.5% battery life for every hour that your phone is just sitting there without you using it at all.

     

    These numbers are just conversions of the official specifications that apple has on this site for the 4s. So if you have your phone on a nightstand while you sleep for 8 hours, and you wake up to a 4-5% drain - Apple clearly told you about that. Or if you're browsing the web on 3G while you're on a bus and "only" spent a half hour, and noticed your battery drop 8-10%? Apple clearly calculated that.

     

    Those of you that are experiencing a drain of ~10-15% on standby only, now THAT is a serious issue and needs to be addressed. I just feel like you guys are getting drowned out by the noise from people who may not have battery issues but may just *want* a better battery life because they are unaware of the 4s specifications.

    It would be a good idea for users to read the following link:

     

    http://www.apple.com/iphone/battery.html

     

    It details the actual testing conditions for various iPhones.  I took a look through them and it is obvious that the tests are made under extremely controlled conditions, and do not necessarily approximate real-world use (i.e. the way an average person might use the phone).  Still, there does seem to be some glitches with iOS 5 software that is affecting the battery drain on the 4s.

    I am terribly disappointed with the battery life..

    I had disabled most things,"Location services" "Notifications" for icalendar, bluetooth and is currently running on Wifi and my battery drop from 100 to 88 in about 1.5hr! I wasn't even doing anything heavy during that time other than browing through the forum...

  • 1AppleADayNoWay Level 1 Level 1 (0 points)

    I've made some important contributions to the thread, like trying to foster respect between users, curiosity, and logic, I've also made suggestions for a more orderly forum, and attracted user attention to the fact that the battery indicator may not be reliable so that you must make sure your device dies before making projections about battery life. That because I have some sympathy for your emotional distress and of course, I had some things to say.

     

    But coming back to Barney Rubble, well, I guess you meant that Android is for cavemen? Why I don't know, I haven't criticized IOS. I haven't said that Android is better. What I hinted at is that Android users pay half to 2/3 less than Apple users for their device, and that Apple and Steve accused Google of ripping off IOS with Android, and have litigated to secure patents accordingly. In doing that they acknowledge that Android is not so much different than IOS. In turn this means, that you guys are mostly paying 200-400$ more for something that's not much different from Android... with let's say a longer battery life, since you guys really make a big deal out of this. You need a really strong distortion field to consider longer battery life for almost half a grand as good value. But I respect your choice. I for one believe in choice and saving money. I'm not about "brand". Hope you understand.

     

    Sincerely.

    Unfortunately, I can't turn roaming off or I have no phone at random periods throughout the day.

  • IM16 Level 1 Level 1 (0 points)

    Another example right there... you got 2 hours of standby time in general there (roughly), and let's say an hour of browsing the web on wifi?

     

    Assuming that, you should lose 1% battery for the phone just being on plus about 11% for the hour of wifi. You should be at 88%, which is exactly where you're at.

  • rh6194 Level 1 Level 1 (0 points)

    I think you should exchange that phone. There have been some users reporting similar heat issues with their phones, although I think having your battery totally discharge in standby in only 4 hours is probably the worst case I've read yet on this board. It sounds like you indeed have a defective phone.

     

    There are still other power issues that are involved either with the 4s design or iOS5, but you seem to have a problem that is outside the scope of what most users are reporting here.

    Disabling the calendar notification fixed my issue as well.  Please try this people.

    I do notice more battery consumption, but not to the extent that you've epxerienced.

    I bought this Iphone 4S on October 14th and It looked odd that the battery seemed to run out of juice even a simple 3-5 web browse or a phone conversation of 5-10 mins. I thought it was only me. As I write this post, my battery indicator  is at 67% after I unplugged from charging since this morning. I had no phone conversations but some web browsing. I did change the setting on the notifications  for calendar but don't think it helped. I hope it is not a hardware issue.

    In my opinion all iphones 4s have big serious problem with the battery..I hope it is only a software issue... Please work hard to fix that bug
