iPhone 4s Battery Life?

If you turn off Cellular Data and Wifi, you will never be able to receive email, use Safari or any other internet application will not work. You will only be able to make/receive phone calls and text messages and run local applications. Also, if you lose your iPhone, Find my iPhone would never work.

I would expect you would get great battery life.

Returned I Phone 4S. Waiting for Apple to solve this issue. For me, problem resolved. Good luck.

email i don't care about, i check it when i have a wifi connection.

Find my iPhone doesn't work, that *****.

I pretty much am operating it now the way i did with my 3GS.

Im at 82% 3.5 hours used, and 16.5 hours standby.

I'm happy.

I have had a battery issue with my iPhone 4s 32gb. Now it started to behave after I set up the settings as shown in one of my previous posts (wifi is always on, 3g off but when I need it I turn it on and afterwards off again, regularly killing the background apps and rebooting the phone when noticing weird batterry drain, etc.). Now I have 20% battery life left after 3 days and 3 nights with normal usage. I still get battery drain of 1% per minute when browsing with Safari on 3G and this goes on even after turning the 3g immediately after being done browsing on 3g. Ussualy I kill all the apps and reboot my phone after using 3g. To me it looks like most of the battery drains are due to software bugs in the iOS 5 and iPhone being like a computer it helps killing the apps and rebooting it when noticing periods of high battery drains.

I remarked to another dissatisfied user of a 4S 32 Gb iPhone - "Have you upgraded to the latest version of the OS? I got one out of the box last Week that ran out after about 6 hours of idle non-use on my bedstand overnight. The Apple store guy suggested allowing the OS to update. While the OS version appeared to be the same (5.0.1), there was also a stealthy firmware update. One of those seems to have cured the battery drain."

After upgrading to 5.0.1 or whatever my iPhone 4S battery has drastically improved :D I can at least use it a full day now without it dying. Although the battery is still not as good as I would like it to be.

So far I have 22% juice left and iTs been:

Usage: 5 hours 26 min

Standby: 21 hours 35 min

Hi Eduard, where is advanced setup forauto/manualp fetch set up?

Thanks for replay

Go to seetings-->Mail, contacts, calender-->Fetch new data-->Advance (at the botton last) and then click on iCloud/Gamil/Yahoo etc. you will get the option Fetch and Manual ...click on manual

Just thought I would post my wifes 4s latest. Both are running strong since day 1. As said, Both are charged every 2 or 3 days depending on usage.

I did a little test to see how long it took to drop 1% from full charge.

Only setting off Is Auto time zone. Everything iCloud synced + iTune wifi synced when plugged in.

iOS 5.0.1 4s 32gig x 2

FiniteAffinity, I have seen your earlier posts and have already tried three Sim cards. Unfortunetly they didn't improve matters. To change the Phone I have to go through my cellular network provider which takes five days so I have been trying to avoid this in the hope that an eventual 5.1 release will help matters. It may be I have to eventually try to get a working replacement.

Your lucky many users are having the crappiest battery life ever like mine !!!!! 15 mins on standby and 98 !!! Where is this auto time zone setting?

My iPhone 4, since 5.0.1, crashes from time to time. It is no more a realible phone as before. Whem I'm a few hours without calls or messages, I take it out of my pocket and I find the screen black wharever button I push, and then I have to reset it by keeping both buttons pushed for a few seconds, having to repeat this operation 3 or 4 times until I get the Apple logo on the screen and the phone back to life.

Until this problem, and the battery one (lasts less than before), are solved by apple, I have to rely on my old Nokia to be always in touch with my coworkers.

I tried everything: killing all apps from multitasking bar, restart, reset (holding home and power button) - noting worked for me.

Yesterday I reinstalled iOS 5.0.1 and restored the last backup also with no effect on battery performance - still 5% drain in 1 hour...

Now I'm setting it up as a new phone completely, hopefully that will work.

(remember i never had such battery issues until thursday last week...)

wow ! u off everything and it lasts that long? its considered that ur battery is still ok mine btw u using iphone 4 or 4s or 3gs?

I'm now on my third 32gig 4s and the battery on this one is the worst yet! I have followed all the advise on the forums and still have huge issues..... Phone lasting around 6 hours standby with couple of hours usage.... Nearly tearing my hair out and considering resurrecting my iPhone 3! When will apple sort this out or recall the dodgy phones????
