Q: iOS 5.0.1 - Made my iPhone 4S battery performance worse!

I must share with you my status - I had my 4S 32GB replaced and this time it came already with the 5.1/

after two days of monitoring - this is what I achieved each day !

Using WIFI 3G calls SMS webbowsing BT and mail push about 100 + emails during the morning hours (2 accouts)

I do have the same problem on two phones now (mine and my wifes) both on verizon network. im down to 62% after not much use in 6 hours.

With literally everything set to on that possibly can be set to on I easily got 16 hours out of my iPhone 4s on 5.0.1 while I digitally 'abused' it the whole day through. With the exact same settings I even can't get HALF the amount of battery life on 5.1. Dispite the complete new clean install without recovering the backup. It's ridiculous.

in order for the battery to improve doesnt the battery have to go throught a few cycles then the battery will improve?

Haha, did they send you $100 for your time.  Each and every Apple employee is worth somewhere around $200000 per year or something like that.  No kidding if they are relying on customers donating there time.  I mean really, those nice Apple people went out of there way to call upon you and bla bla bla. 

Each trip to the Genious bar to get such great service also costs an an average of $25 just in Mileage and car costs, and that does not account for time lost.

I really see them scrambling to protect stock holders from hearing they are ready for the biggest recall ever.  A software issue causing battery problems can be very very dangerous. 

After upgrading my iPhone 4 to ios 5.1. It increased my battery backup. Cheers !!!

Not a good solution, I use my phone for business soI have a lot of settings set to connect to my office and network and documents/data related to business and so forth.

 

I have installed previous updates without doing any restore and any problems with my battery life.

 

As you all can see, this recent update has a bug.

 

And for those who are posting without any problems, why post at all unless you are just being an antagonist? We are looking for owners who have the same issues with this update so Apple will offer a fix to this problem.

Hey nbercasio,

Wasn't sure but are you referring to my comment?

Haha, then why on earth would you be wasting your time on a blog regarding horrible battery issues.  Another Apple Cheerleader.  Go away.

Hello,

From my experience: it is quite strange. After the upgrade to 5.1, I stated a quite big improvement in battery life for the next 4-5 days. (only 35% consumed in a working day).

Untill yesterday, happy. then I manipulated some settings to see if I could improve it more:

- deactivated "automatic siri"

- deactivated all location services

---> 5h later, coming back home, my Iphone 4S was dead. Today, it consumed 86% in 6h. Terrible!!!

Important: I noticed that it's temperature in my hand was higher than normal, even in standby. then I shut off 3G. Temperature got back to normal, but battery still leaking as fast.

I am not 100% sure that the cause of the problem is 5.1, because it started after manipulating settings. I will full-restore to see if it improves.

I fixed my phone originally by turning off iCloud and push mail. (see my previous posts to see how I did it.

I wanted to do an experiment so I did a clean install not from backup and still had problems. Turned off I cloud and push mail and battery is back.

It was for Petav but the last paragraph was in general for those who are just cheerleaders.

Ok, Apple too reached out to me and I thought the issue was fixed as past few days of light usage battery ending day at around 15% or so.

Today with heavier usage (using google maps), some texting, and no calling by 1pm it was 40%.  Battery has been warm all day.

25% battery left, 28 minutes of usage my battery is now 9%.  Don't think this is acceptable.  Will call the Apple guys back and have them look at this issue.  Hope it can get fixed cause this battery stuff is not acceptable.

Still the same bad performance here with my 4s. On 5.0.1 it really lasted at least 14 to 16 hours with heavy usage and everything thinkable turned on. With 5.1 I don't get HALF of that time with moderate usage and push mail off, wifi off, Bluetooth off, iCloud off etc. Having to turn all options off is ridiculous in the first place by the way. You don't remove the interior of your new car to make it lighter if you can't get the promised mileage :)

Bottom line is: this update 5.1 really leaves me worried about my battery status all day. Stressfull thing. I need the phone for business.

14-16 hours is well above and beyond the expected range for battery life, so you're compaining about a non-issue. If you get 7-8 hours then you're in the norm.
