Q: iPhone 4s Battery Life?

These are my results after updating to iOS 5.1 and doing a full charge.

Needless to say, I am impressed!

If you don't live near an Apple Store, you can send the phone to Apple and have them do the firmware fix.

Yes, you will be without your phone for a wee bit, but if you want it fixed, you may have to do that.

Any company would want you to exhaust those options before they replace, and I highly doubt that Apple would not replace it if it's truly a bunk phone.

Iphone that i bought yesterday with contract is losing like 2% battery life in standby per hour...think im gonna return it..

that means it could go about 2 days.  What did you expect?

Maybe he naively expected it to last 200 hours (8 days) on standby, as Apple specs states.

He failed to search all 780 pages of this thread and and rest of the internet - he would find that nobody ever claimed his/her 4S to last 8 days on standby except the Apple specs.

So Do yoou Think I have to put everything OFF. Sound like ridiculos....

You know what? This busines charge GOOD MONEY for this one? CAME....... Do you have any idea netwoks and phone company CHARGE FEES>>>>>>????? This is stupid...... And Its not fear to have such apologys those days. So where its the new Technology? Just ask more money and nothing High quality? They area GINIUS???? 

I have serious doubt..........NO more apologys........

I have also had this problem with battery life. The trick that I have learned is to turn off wifi. And it will not die so fast.

Well, I can't read the labels, but if that is 1 day 14 hours, then you are doing fine.  To me, any phone that can last through a full day of use before needing a charge is fine.

Your expectations may vary.

It is 1 day 14 hours of standby and 5 hours 9 mins of usage. I see it is improvement over 5.0.1 and 5.0, plus I was reading on different forums that Galaxy S2 (I consider the closest competitor for iPhones) runs flat in 8 to 10 hours, so no real reason to change for me.

After upgrading to 5.1 I have nearly the same numbers as you I couldn't keep alive my phone (4s) more than 30 hours with everything turned off using 5.0.1. I was looking for a solution, found this thread, been reading it for several weeks, and some guys nearly convinced me, that less then 1.5 days of standby is a correct time with such a strong hardware (twice the ram, twice the cores than the 3GS), but somewhere deep inside I knew that these couldn't be the problem, since my 4s consumed 2% of  battery in 1 day without a SIM card installed. The only thing I could blame was the radio chip - baseband combo, and the phantom usage. Now, with 5.1 onboard, the "Phantom of the iOS" disappeared, the baseband stepped from v 1.0.14 to 2.0.x and the battery life is awesome now. The BT, GPS, 3G and Siri are turned OFF (I never use them), but mobile data, sometimes the wifi, iCloud sync (except photo stream), push, notification center, mail with 2 accounts, auto brigtness are ON. With these settings my results are:

Thanks Apple, and thank you all Guys

Hi guys, I am glad to tell you that since yesterday when I got a NEW handset (4S with 5.1) in return to my most likely faulty one which started to lose battery after the 5.1 UPGRADE last friday -  my life are much better.

There is NO doubt the problem was with the handset's battery.

Now for instance I have it with PUSH mail, calls wifi BT and after accumulative 2 Hours of USAGE within 6:30 hours of SB I am down only to 71% !!!!! like 30% in 6:30 hours.

Lithium batteries do NOT have battery memory issues.  Don't run the battery down to nothing.  Its not good.  Only the old generation NiCad have a memory.  There's something better than Lithium coming down the pike.  Just hold on to your hats.  Its kinda big.  Its going to change lots everywhere in many ways.  For now however, lithium is the best commerically available product for Joe Sixpack and Shirley Temple.  Stay tuned for the update. 

Thank you kindly.  I wanted to know this and didn't know where to procur.

Hey....

I was going through my old stuff in the cupboard today and found two of sony ericsson's usb power adapter. It is rated at 5V and 750mA, 5V and 700mA output while 4s' adapter is 5V and 1A. Is it okay to use sony's charger because I have two of them and I would like to keep the chargers plugged in, in two bedrooms and living room and when needed, switch it on and charge my iPhone. I have a couple of Apple USB cables. So I was just wondering if you could tell me?

Technically it shouldnt harm as the rating is lower than iPhone's adapter rating, but are there any other build aspects of the adapter apart from power outputs that I need to look into before I use?...

After reading through a lot of these posts, I'm amazed at some things:

1. Apple replacing phones for what is an obvious software issue related to some hardware configurations.

2. People posting "solutions" which involve losing most of the functionality of the iPhone by turning off everything.

If I wanted a cheap flip phone, I'd have bought a cheap flip phone.

Using customers to beta test releases is not acceptable. Great business model.

My advice: take your iPhone back for warranty replacement, this is Apple's prpoblem, not ours. Maybe next time they'll do a better job.

you are absolutely right on both points !
