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

I must be one of the lucky ones... No battery life problems at all on iphone 4s, even after 5.1 update.

my battery is now in auto run out since installing 5.1 or whatever the new one is.

losing about 10% every twenty mins.

everything is turned off as suggested by, well everyone. but actually whats the point in having an i phone if you have to turn everything off? I didnt buy this phone to spend all weekend trying to fix it.

will give it a week or so then drop it on the shop to sort.

Another update... I noticed that on my Windows machine, the iCloud service bookmarkDav was periodically consuming processes and had a huge memory footprint (600mb). I have always had this wierd problem were if I enabled bookmark sync I would get copies of coppies of the same bookmarks.

So anyways I am thinking that maybe the bookmark syncing is broken somehow so I have disabled the iCloud bookmark option. I did notice that since disabling the bookmark sync the process usage on my phone is down.

Seems like less battery consumption so far but we shall see from a full charge.

yep. same problem. Since I updated to 5.1 the lovely spinning wheel right next to the 4G icon spins and spins and spins on absolutely everything I try to do - on and off wi-fi. My battery was fully charged this morning and now it's at 8%.... and I hardly used it today.  so not cool. :/

Will Apple software engineers and programmers read and follow this forum?

or they have given up with this problem so since november until now no clear and definite solution?

Here my usage statistic after try solution from yaarab

Usage :

1. WiFi always On and connected

2. Celullar Data (3G) Off (when i used WiFi)

3. SMS almost often

4. Online Game (PyramidVille & Flight Tycoon)

5. Offline Game (GreenFarm2, Smurfs & FishingKing)

6. Yahoo Messenger always on

7. Facebook & Facebook Messenger always on

8. I have 4 mail account and fetch every 15 minutes

I think it's just improve a little bit in my iphone,. now trying SmogTM solution,. hope there is a significant difference,.

i'll post the result tomorow,.

yep its great we are all tring to fix and live with this ..but, we bought these phones in good faith and in fact with very high expections. apple has a problem and for me at least i expect them to make a public comment asap.

true this wont help the share price,, but all i want is a phone i cant leave home with for more than two hours.

hey everyone

firstly yes the issues with the battery is well......poo to put it nicely.

I may have found a way to combat this for us iPhone 4 users ( not sure whether this works on the other models as I only have the 4 )

I upgraded the other night to IOS 5.1 and my battery ran out in half a day without even being used at all.

I decided once I had it at full charge again to totally drain it of power via the light on the video camera.

Once the discharge was complete I just plugged it in at the wall and my iPhone booted back up and charged merily all night (approx 8 hours)

I have used it all day today for various calls sms etc and I am currently sitting on 86% battery life still.

Now saying this I am hoping that at some point today it doesnt jump down by 50% in life and prove me a liar but so far so good.

Worth a try to make your "mobile phone" mobile again instead of hanging around a constant power source to keep it going

Here are my stats since last charge (yesterday):

Usage :

1. WiFi always On and connected (since at home)

2. Celullar Data (3G) Off (when i used WiFi)

3. Usage : 2hrs 6min

4. Standby : 18hrs 25min

5. Battery percentage : 57%

And all the usual notifications /locations off.

Hi would you be so kind as to list all your apps,just maybe you have the answer!

hey Sup

who was that aimed at as lauriefromqld has only one post??

I purchased this phone for what it could do, not for what it could do if I turned off all of the bells and whistles that influenced my decision to purchase it in the first place!  This is my result after using the phone for nothing but internet browsing over a wifi connection at home.  Oh yeah, my mail fetches every hr or so, and I have installed the 5.1 upgrade.

My 4S is installed with iOS 5.1, and it seems nothing better. 1 hour and half usage (Viber over wifi, sms, game for 15mins)  battery drop to 80%, with 2 hours standby.

Sorry but that's rubbish. I charged my phone last night to 100% went sleep and woke up and it's now at 20%. No usage at all as I was asleep. Now rather then just heading out I have to wait for it to charge again. It's already dropped another 4% while I'm reading this thread and I'm only on page 3! This is awful Apple!

This is your phone, not Apple's. You need to figure out what applications and settings you have that drain your battery.

If you have not done so, you may wish to use Reset All Settings, or at least Reset Network Settings.

If this does not help, you need to find out what application is running all the time on your phone and take measures to either disable it, or reconfigure it.

By the way, why would you remove your iPhone from the charger overnight? Just leave it plugged in and in the morning you start the day with full battery.
