Q: iPhone 4s Battery Life?

Hi Laura! Take a look at the iPhone configuration, are you sure that you have modemfirmware 1.0.14 installed?

I thought I'd share this update regarding my 4S battery.

Last night, I was toying around with Instagram and the app crashed and then, suddenly, I got an error telling me that my SIM was invalid. Huh? The phone was reporting that I no longer was connected to AT&T. Uh, okay. So I rebooted the phone and it took a little while to get it back and then it was normal. Then, I was doing something else and I got the Invalid Sim message again. Hmm. I turned on Airplane mode and waited and turned it off again, seeing if the phone would find the sim again. Nope.

Now while I was doing this, the battery was draining. Not super fast, but not as slow as it was before this happened. I did notice the phone getting a little hotter than I thought it should usually be.

After I rebooted again, I noticed the little purple triangle of Location Services light up on the menu, as if the phone was accessing its location. This is after a boot up and after I force quit all of the apps that we're running. Hmm. I went in to turn off location services and when I did, the triangle stayed there. I went to turn LS back on and the switch was slightly greyed out and it wouldn't react. Eventually it did and the triangle went away.

The phone was still not seeing the SIM. So, I got my super duper iPhone sim removal tool and popped the door open and took out the sim and then put it back in. After a moment, AT&T was back up and everything looked normal.

The battery drained a bit, but not bad. I plugged in the phone to the iPad charger I had sitting next to my couch. Ithe battery was at 79% or something. It charged back up to 100% pretty fast. I was wondering if it was a problem hooking up the iPad charger to the iPhone because of the power differences, but I haven't heard that you can't do it. The phone did get a little warm though. I wanted to charge it up to 100% so I could see the usage stats.

Anyway (phew), by the time I headed to bed (after falling asleep on the couch for a few hours) I noticed the battery was down to about 96%. I decided not to hook it up to its charger overnight to see what would happen. Here's what the battery reported when I woke up:

It was still at 95%!

When I started writing this post, exactly 1 hour after waking it was at 90%:

Right now, it's at 86% and draining slowly.

What I did notice in the Usage stats, the Usage time has decreased a lot from previous days, as if something is no longer being used as much as it was before. Hmm. (BTW, I did turn location services back on. And Siri is on too)

Anyway, I wanted to share my experiences with you all (and, presumably, Apple) to see if any of what I did could help to fix the battery issues. It's too early to know whether I've fixed something completely or if it's just temporary. I'll report back if things change. Maybe pulling out and replacing the SIM card had something to do with this. I don't know.

Ooooooooo... Thanks for tip.... !  I just looked mine says 1.0.13.... The version says....9A405 What do I need to do now? Willing to try anything!!! Hate giving up!!!

The correct versions are modem: 1.0.14 and Build 9A406 - to get that, connect your phone with cable, open itunes, do a backup first! if you have icloud backup enabled, go to iphone configurations, in the icloud menue do a backup, and wait till it finished - after that go back to itunes, click on "restore" and do a factory resett! itunes will automatically load the new iOS 5.0.1 with build 9A406 - if it finished downloading the new iOS, it will do a restore. then you can restore your backup. thats it!

How weird! That's what I did following the instructions earlier in this forum (except the iCloud bit as I don't use it!)! How strange that mine didn't update the iOS....wonder why! Will have to try it again. Thanks for spotting that it hadn't updated the iOS. Fingers crossed next attempt will fix it!  Thanks!

hey laura i just did a backup from itunes to the pc  and click "restore" and did a resett! it automatically downloadws the new iOS 5.0.1 (9A406) -after the downloading finishes it restored my phone and i restored from my backup. i now have iOS 5.0.1 (9A406)

this is total and utter rubbish

if you turn off

1}bluetooth

2}wifi

3}3g connection

4} reduce screen brightness to 40%

5} from new run it till it goes flat and turns off

ignore the 20% level alert

then fully charge the battery

using any charger

then only use what you need in the way of features

my iphone4s  runs fine for so far 4 days

9 hrs uptime and more than 3 days now in standby

and i am still at 40%

and i will wait till again it goes flat

and trickle charge it via usb next time

so

do this and it will work

at first it used the battery fast

now after this method it works for so far ~ 4 days with 40% bat left

perfectly acceptable for me

anything else is just daft speek

out the box i di do a soft reset

as i feel my service provider just added the latest os to an older phone

juudging by its package date... {some three months ago....}

That happened to me as well. After have the refurbished 5.0.1 installed sometimes I have battery drain even with the phone plugged to the charger!!!!!!! And it didn't even get warm...

I really don't get what is going on with this.......

i fell some users may have damaged batteries

due to poor inital setup and charging regiem...

... this is all i can think causes the issue

for me bluetooth did drain the battery very fast

but after the inital cycle its fine

as i just use it for transfer

and dont like default settings

something i learned many times from registers

is like bios the firmware has two parts

upper{bios} and lower {bootblock}

so they need to be in 'sync'

and this can take both a soft and hard reset

if you hard reset any apple product it will default to factory

so you need even i think to add the latest o/s again if you hard reset it

so soft reset after flash and i would if you have issues

hard reset and then soft reset

then add lastest o/s again

soft reset again

and as new phone begin

you MUST cycle the battery a few times till its stable...

i will add

some 'set settings' icons are needed

a quick way to simply set on what you need

other than click like crazy to add

ie  wifi on on main screen etc...

I got an iPhone 4s this week and very disapointed with battery life. It's my first iPhone and when using any app it goes down by a % a minute! When I get home from work the battery is at around 15% and I have to charge it. Is it something I'm doing or is the phone just like this?

For alot of us it's just like this for now, I'm hoping on some Apple magic to fix it though...I refuse to believe that it can't be better, and alot of other iPhone 4s users are reporting good battery status on their phones. I have just not seen it on mine yet.

There are alot of advice on how you can try to improve it, personally I have given up on all the different things to try, I don't feel any of them have helped me much. I did install the new modem firmware(new 5.01 update), and feel that my battery has improved a bit, but it is to early to tell yet.

To "ilikebigguts" - this is a great tip! Although my phone says "Your software is up to date", it is not the 9A406 build, but the9A405. So, I will follow your advice. I just backed-up my stuff to the PC, like "axphiean" did, and am ready to do the factory reset. Question though: will all my apps still be on the phone, or will I have to re-install all one by one? I don't care about my pics, movies, music, since I've already transfered them to my PC... I am worrying about my already installed Apps... Thanks!

Hi Guys, usage 5 hours 52 mins standby 1 Day 6 Hours this is on 1% battery life left so im quite happy with this at the moment
