Want to get more from your iPhone battery? Check out these iOS 5 battery saver tips!Sascha Segan of PCMag carries out a test, putting a new iPhone 4S running iOS 5 up against an iPhone 4 running iOS 4 and another running iOS 5. The results are interesting in that basically there’s little difference in the time taken for the Aspire One 10.1 battery to run out between the three handsets.
- iPhone 4/iOS 5 - 6 hrs 55 mins
- iPhone 4S/iOS 5 - 7 hrs 27 mins
- iPhone 4/iOS 4 - 7 hrs 29 mins
Conclusion - It’s iOS 5, not the iPhone 4S.
But … it’s not that clear cut. I’m hearing from some iPhone 4S owners who aren’t seeing any problems, and others who are seeing their satellite 4090xcdt battery literally drain away in front of their eyes. Other people are seeing the same issue on the iPhone 4 and iPhone 3GS with iOS 5, while others aren’t seeing any problems at all. Something is going on, that’s for sure, but it’s hard to put a finger on what the issue actually is. Personally, I think the problem comes down to usage, which means that Apple will have to rely on telemetry sent from handsets to narrow down the cause.
RE: iPhone 4S battery drain - Is it the handset or iOS 5 that's at fault?
Good thing Apple is working on the issue, perhaps the new OS was released a bit prematurely. Access your home PC from your Apple iOS device by using the 2X client App from http://www.battery-store.co.uk/
RE: iPhone 4S battery drain - Is it the handset or iOS 5 that's at fault?
@tcsi@... I think it's because of those Flash videos that you are watching all day... oh wait...
Not funny, since no one at Apple, including Jobs, ever said that phrase
@SplatterFest: The actual phrase was that if you experience problems, hold the phone differently. Most of people did not experience any problems with antenna (less than two percentage ever wanted case even when it was offered for free), no matter how they held the phone, so, of course, there was no "wrong way" to hold the phone, and no one at Apple, including Jobs, ever said that phrase.
It is typical media, which are tabloid, twisted the phrase for cheap way to earn clicks.

Before I turned my i4 into an i4Touch, with iOS5 the phone became sluggish but the Dell inspiron 1720 AC Adapter battery life was relatively unchanged.
Similar on my iPad2 - iOS5 introduced a random keyboard issue - Apple wants to replace it but will not redo the engraving (it was a gift). Issue: the keyboard will randomly close when typing.
Have several peers who have the 4/4S and some have an issue, others not.
It will be interesting when/if Apple finds the answer.

Seriously, why do "haters" with no actual experience with the device feel the need to comment?
As someone that actually has the device for 2.5 weeks now, I'll share my actual usage. Overall, the battery life is actually very, very good. I did experience the Lenovo 42t4806 battery drain issue last Saturday. There seems to be a software bug relating to location data. Once I experienced the problem, the battery did drain rather quickly. After recharging, it continued to drain. I reboot the phone and all was good again. No problems before that, no problems since. Average every day dell inspiron 1420 ac adapter battery life is certainly better than average for the industry.

RE: iPhone 4S battery drain - Is it the handset or iOS 5 that's at fault?
I was seeing rapid battery for Dell inspiron 1525 depletion with iOS 5 on my iPod Touch. I don't think has anything to do with the hardware, it's the OS.
For me, the thing that was causing it was having Notifications turned on for Calendar AND having my calendars sync with my work account (which is using Outlook).
When I opened notifications (swipe down from top of screen), I could occasionally see the calendar section going haywire, posting the same appointments over and over again.
Turning off notifications for the calendar app fixed my problem (I left everything else as it was: Alerts, Badge App Icon on, View in Lock Screen on).

RE: iPhone 4S battery drain - Is it the handset or iOS 5 that's at fault?
@jessespears - I had this same issue. It's a conflict with Exchange. The genius' at Apple told me to do a complete restore and setup as new phone (not from backup) and it fixed the problem. Somewhat of a hassle setting everything back up, but now I have notifications w/o glitches and great Dell Vostro 1400 battery life.
RE: iPhone 4S battery drain - Is it the handset or iOS 5 that's at fault?
@jessespears I have an iPhone 4 with IOS 5. I left for work with it this morning at 100%, and used it for reading a story for about 1.5 hours, and had a few text messages, and otherwise used it as normal. I came home with 80% charge. At that rate, I would get several days use. I suspect that the Inspiron 6400 AC Adapter battery drain problem is that people turn on services that they aren't really using, and leave many applications running when they don't need them active. Basic good battery conservation will take care of the problem. I don't often cross time zones, so that feature was already off. No problem here.
RE: iPhone 4S battery drain - Is it the handset or iOS 5 that's at fault?
The main difference in iOS5 is how Location Services and the apps that use it, ie, the new Reminders app, have a huge affect on the Sony vgp-bps9 battery. There seems to be a larger ammount of LS based activity which is keeping the phone more active. If not needed, I turn off location services unless I am doing something that needs it. This greatly extends the battery time.
RE: iPhone 4S battery drain - Is it the handset or iOS 5 that's at fault?
I have an IPhone 4 and I could go two days without charging. I installed IOS 5 and now I just watch it drain to the point where there are days I cannot make it through the day. And my usage has not changed. I turned off the time zone feature and a couple of other location services but that did not help. There is no doubt the new IOS is the issue
4-5 hours on standby!
What you've tested is not the problem for myself and other new iPhone 4S users. The phone was fine for a couple weeks but starting a couple days ago, I'm only getting 4 to 5 hours on standby! If it's unplugged, the phone inspiron 1525 battery will be dead in a few hours no matter how little you use it. I've even turned off a number of services and it doesn't help. My best guess is it's an iOS 5 bug thats only affecting a few users. But it's also possible that there's a hardware defect with 4S batteries.
Have you tried to reformat and reinstall?
@Z3rian
"The phone was fine for a couple weeks but starting a couple days ago, I'm only getting 4 to 5 hours on standby!"
I had to do that with my iPhone 4 a few months ago. I had noticed that the Universal External battery life had fallen substantially. Reformat and reinstall fixed it. Just restore your iPhone as a new device and that will probably fix it.
Funny how the very cure that smug OS X users deride Windows for is also required for the iPhone.

I attended a workshop at an Apple store over the weekend and was surprised to learn that every application that I had opened since getting my new 4S was open and running in the background, which was basically every app. I had noticed that the speed of the phone had been getting slower. An Apple person showed me how to turn them off. Double click on the "on" button and you get a line of icons along the bottom of the screen which shows you the apps that are open. Hold your finger down on one of the apps to start them jiggling. You get a "minus" sign that allows you to shut off each app. It doesn't get rid of the apps.

That isn't quite true
"every application that I had opened since getting my new 4S was open and running in the background"
No, they are not all running. That is a history of programs you've used and yes, some may be running, but not all of them are. You can test that by turning off the phone and restarting it. You'll notice that all the icons are still there even though none of them are actually running any more.
It is a good suggestion and yes, I've done that myself in the past. It did not fix the Dell latitude d630 battery issue for me but it is a good step 1 since it takes less time than a full reformat and reinstall of iOS.

vulpine: read my post more carefully
If you actually bothered to read it, you would see that I was suggesting a fix that I employed months ago, before iOS 5 came out. iOS suffers from bitrot and yes, I noticed that my iPhone was getting slower and slower and the Dell Inspiron 1545 AC Adapter battery life was getting worse and worse. I had not changed any of my settings for months. Reformat and reinstall worked.
Will it fix Z3rian's issue? I don't know but when Z3rian said that his phone was fine for a couple weeks and only started acting up recently, that was very similar to what happened to me a few months ago, long before iOS 5 came out. It is possible that his issue has nothing to do with iOS 5, especially if it was working fine after the upgrade and only started acting up in the last few days.
Fortunately, iOS bitrot is easy to fix. Just reformat and reinstall the OS. It only takes a few hours.

Noticing it most with LS on
I don't use the location services much, but when I set a Reminder to go off when I get home or leave work or whatever, the GPS flips on when you create the Reminder and doesn't turn off until you mark the Reminder as completed. Sometimes I forget to mark it as completed right away and my battery for Lenovo 3000 G530 drains FAST. When I don't use any location services the battery lasts much longer.
My privacy is too important
"which means that Apple will have to rely on telemetry sent from handsets to narrow down the cause."
I turn that off since I do not want Big Brother Apple spying on my iPhone. I've told all my friends and family to turn that off too.

I had the same problem on my Android handset. I figure it is just par for the course so I bought another battery that I keep charged and swap when needed...
Maybe just get a spare battery..... OOPS! I guess not....
Maybe style at the expense of pragmatism is not the best design tenet. Just get a Dell XPS M1530 AC Adapter battery booster and quit yer complainin'.... Or stop using your phone.... Turn it off and the battery will drain much more slowly....

Just do it
Apple will have to rely on telemetry sent from handsets to narrow down the cause.You could save a lot of time if you would go ahead and write the article now about how Apple is spying on users to find out how they use reminders and location services. That way you'd have the article in the drawer when somebody finds out it's happening.
RE: iPhone 4S battery drain - Is it the handset or iOS 5 that's at fault?
I feel it is iOS 5 fault. My phones not even 10% filled have the same issue iPhone4/iOS5 and iPhone 4S/iOS5. They both drain pretty fast. Yes I close my apps as soon as I am done (close means literally killing them, not minimizing or tombstoning them). I used to get good three to 4 days without charging, but I am required to charge everyday now.
I noticed this with my wife's and daughter's iphones 4 with iOS5 too.

"S" now stands for "Slow" on 3s
After upgrading to iOS5, my 3s not only had fast IBM thinkpad 770e battery drain but was sluggish and sometimes refused to open applications on first try. I did a reset (again with iOS5), and I no longer see a battery drain. But the sluggish behavior remains. Bad situation.
Have you considered just buying an iPhone 4S?
@wls
That should fix your problem.

I also have the 3G"S".
Yes, phone is somewhat more slow/sluggish with iOS5 than iOS4, but what can one expect. New OS with more features. No major impact, and I will upgrade to a 4S soon regardless as I am overall VERY happy with my iPhone.
As for lenovo 3000 y510a 15303 battery drain on 3GS and iOS5, no change since iO4, but I also always have limited push notifications, and only allow certain apps to use location data. No need to provide that to apps where it really does not matter.

RE: iPhone 4S battery drain - Is it the handset or iOS 5 that's at fault?
Finally! Someone has touched onto the real cause of the battery drain; it's not just the hardware.
We saw an almost exact duplicate of this issue with the release of iOS 4, though that release also put a big hit onto the system's performance. This time the performance, if anything, is better than ever, but the Dell xps m1210 ac adapter battery is suffering as a result.
Four days standby now down to 2 on fairly light usage on an iPhone 4. I think it's due to too-frequent calls on the radios for iCloud synching.

RE: iPhone 4S battery drain - Is it the handset or iOS 5 that's at fault?
None. The battery drainage is caused by poor signals (WiFi or 3G) in the area where you are using your phone. If you are in a place with good signal strength the toshiba pa3383u-1brs battery lasts longer. GPS is also a battery drainer. Turn it off when you don't need it.
RE: iPhone 4S battery drain - Is it the handset or iOS 5 that's at fault?
I had the same problem, and I noticed that the new notification service combined with some apps that are very of the "look at me" and "see what is going on" type, make my iPhone get awake very often. Specially 4square, its notifications came every 5 minutes or less (a lot of friends use 4square) and it maintain my iPhone with the screen active most of the time reducing sony vaio pcg-sr battery life to less than 50% of the usual time. After I deactivated the notification messages for the most notorious apps my battery life returns to normal.
some sprint 4s phones have defective batteries
I just had mine replaced at the Apple Store, after they reset it and it still drained 1% ever couple of minutes. I have another friend with a Sprint phone who is headed for replacement today. the new phone has great toshiba satellite a100 battery life. Looks like apple needs to take another look at manufacturing quality.
RE: iPhone 4S battery drain - Is it the handset or iOS 5 that's at fault?
Is it really OS5 or is it the design to integrate CLOUD services and continually talk-talk-talk? Perhaps this is Steve's way of having Appletalk come back to life on a network ?
RE: iPhone 4S battery drain - Is it the handset or iOS 5 that's at fault?
Are systems without Cloud services enabled experiencing this drain? My little iPod upgraded cleanly and I experience no issues. Perhaps with Cloud services enabled this is Steve's way of bringing chatty cathy Appletalk back to life on networks?
RE: iPhone 4S battery drain - Is it the handset or iOS 5 that's at fault?
I'm a corporate user with 65 iPhones on both AT&T and Verizon. All my phones went bad on Tuesday, Oct 4th, the day they announced the 4S. Users may want to open a ticket with their carrier to see if the phone is dropping on and off the carrier's network. This would cause location services, mail, calendar, and contacts to sync continuously and not turn off.......running the battery for Lenovo Y560 down in hours. I believe that a few tickets open on this will point Apple in the right direction.
RE: iPhone 4S battery drain - Is it the handset or iOS 5 that's at fault?

Complete restore and setup? Does this entail Acer btp-43d1 battery removeal as I have found necessary in a Blackberry?
SOLUTION
Hi, I found one solution to limit battery depletion : Desactivate "abroad data sending" option in IOS general, network menu. Drawback : No more auto notifications..
Errr.....
I wonder how the testing was done. Was it scientific? I doubt it. One phone for each model/OS with different carriers. Better off at least by choosing just one carrier and multiple phones per model/OS. Even worse, the PC Mag article said "...they're of slightly different ages so the dell 6y270 batteries...". Duh! Would of been smart to use new phones with new batteries.
Errr.... even more
@Gisabun I wonder how the carping is done. Is it scientific? I doubt it. One anecdote for each troll. Better off choosing just one Android phone, because Android phones don't have these pa3383u-1brs battery problems...
Er, yes they do.

Battery drains faster when you work the processor. Your iPhone 4S has long lasting battery for Dell Inspiron 1521 , because you may not watch video or surf the web on your phone as much as others.

Apple had their 1ghz A5 processor overclecked to compete with 1.2ghz Samsung G2. Now Apple will provide the new software fix to correct the iPhone 4S overclock processor.
Once the fixs for the new iOS 5 gets updated, there will be new complaints about the sluggishness of the iPhone 4S.
