Q: iPhone 4s Battery Life?

http://www.usatoday.com/tech/news/story/2011-11-02/apple-acknowledges-iphone-bat tery-problems/51049458/1

u can also visit google.com and write ( ihone 4s problems and alot of pages will be available for you)

you welcome

Thank you for the link (6 week old and before 5.0.1). Anyway, if i understand that right, i supose they are still trying to find the problem and then act fast, lol! Maybe they design a new bumper!

Finally lost patience with my iPhone 4 and went to my genius appointment. It is 13 months old and they still offered to swap it for a new one there and then. Brilliant.

So far battery life is perfect, it dropped 4% overnight instead of 40! I've used it quite heavily since early yesterday morning and I still have 45% left. So happy.

**** You!!!

Hi all,

I finally got around to trying something new - previously I had performed a factory reset and setup as a new iPhone, to see if any of my apps were causing the high battery drain.  I had minimal features turned on (I had exchange syncing set to push) and the battery life was great (<10% overnight instead of 50%).

The next stage was to connect to iTunes and restore the iBooks app and 4 PDFs, I setup gmail, and I turned Find My iPhone on. That's pretty much it, and the battery life dropped by >45% again every night.

Last night I tried the following:

Perform a factory reset (Settings->General->Reset->Erase all content and settings)

Setup as a new iPhone

Setup wifi

Turned Siri on

Removed most notifications - I don't need most of these

Set Location Services on (Find my iPhone, and Siri on, although I turned off all System Services locations)

Left Bluetooth on

Setup Exchange for contacts, email, calendar, tasks-set to push

Setup gmail for my email - set to Fetch

Setup gmail for the family calendar - set to fetch

ICloud is off as I don't use it yet and it would complicate this test

Downloaded iBooks from the app store

I did NOT connect to iTunes yet.

Result - I only lost 9% battery life overnight!

This is amazing as I had expected it to drop lots due to the email connectivity.

Maybe the battery drain issue is related to connecting to iTunes?

Next steps - leave it like this for a few days, then either start adding apps back (facebook, google, utilities, games etc - all 142 of them!) gradually or I may connect to itunes with as little change as possible - and see if the problem reappears instantly.

Hope this helps everyone else too.

Hi Guys,

I'm from Italy and here it's the same ... everybody is complaining. Hope it ends up to be a software issue otherwise Apple is in super trouble. Well at least American customers have the option to make a class action against apple and have their money refunded. Here in Europe ... hope we could do the same.

Anyway ... here my best performances with my 4s:

- usage up to 6 hours

- standby up to 10 hours

All my settings on but wifi, bb and icloud.

Best regards.

Battery life is still atrocious. Soo ****** of that apple is still continues to fully acknowledge that this is a widespread problem.

Sitting on their a**** with not a single update or announcement in sight.

Got my iPhone 4S two days ago, set it up as a new iPhone with all the "right" settings I had on my iPhone 4 to get a great battery life.

But it's so bad! Even with Siri turned off. It's really really bad...

Easily fixed though - send it back, get a refund.

Apple must have a VERY large pile of returned 4S's by now.

Without the hope of getting a "good" device in return!? Look around in other threads. I'm pretty sure it's software related.

Hello,

i´m not so expert on this but since i´ve made a full reset and recharge my battery, everything have changed. Before that my battery would last for only 1 day and not pushing so much... overnight the battery usually droped 20%.

In this present moment, the last time i´ve charged my battery was 1day and 18 hours ago and i still have 55% of battery. my settings are basic. i have 2 email accounts, facebook, weather, see newspaper, i use bluetooth while i´m driving, use a lot of wi-fi, no 3G yet because i don´t have a plan with my carrier yet, i took some photos... well, i will continue to test my phone and see if it keeps working like that.

i was disappointed but now... well let´s wait and see the next few days.

thanks

I also suffer from the battery problem. I was only getting 20 hours standby with circa 2 hours usage before my fully charged iPhone 4S went from 100% to shutting down.

I bought the 4S on UK launch day, it was running iOS5 - I subsequently used the OTA upgrade to iOS5.0.1. There were no changes to battery life. I've spent endless hours trying this, disabling that, resetting the other - pain in the arse.

Two days ago I said **** it, downloaded the offical 5.0.1 IPSW, disabled iCloud Backup, backed up contents to my iMac and done a complete restore.

Happy to say that everything restored perfectly - the only setting that I have thats different now I'm not doing automatic back ups to the iCloud.

Battery life is now significantly extended to something far more reasonable, been over a day now and over 3 hours usage of mixed usage, passed around 40mb of data over 3G etc etc

So of course, this is no groundbreaking new solution however just something that worked and fixed my problem

I bought an iPhone 4S direct from apple three days ago. Best it up with iCloud backup and everything turned on except Bluetooth.

Instantly unimpressed with battery.  Didnt do any measurements at this point.

Turned off all location system services and turned on Location icon.  Measured the standby battery usage and calculated a standby of about 8 hours.  Can remember which way around I did these two things.

Did an erase and reset.  Restored from iCloud.  Could see that the Set Time Zone was continuously polling the location.  Turned only this location setting off.  Left phone and measured the standby battery usage and this time noticeably better.  Calculated a standby of 50 hours.

Not the 200 hours expected by Apple but above the minimum I need I think.

Can't be sure if the reset changed anything or just turning off set time zone.

I will check it again next weekend.

The constant polling from set time zone is obviously a bug.

Hi,

Everything ON except iTunes synch, maybe a good serial number.

davidch - I finally tried your suggestion, except instead of letting the battery drain completely I let it go to 1%, then recharged it to 100% while asleep.  I unplugged it at 5am Saturday and as of this morning it just went to 49%!!!  I'm still afraid to let it drain all the way, I don't know why.  I figured if I was still having problems I would do it, but this seemed to work as I haven't recharged it since then.   Now I have another question.  When I go into Usage I get nothng.  No percentages since last charge, no standby.  Why do you think that is?  Maybe I turned something off?  I turned off all system services except Cell Network Search and Setting Time Zone and I've been on wi-fi during this process.  Thanks for all your help, at least I didn't have to go into the city to Apple.  Let's see how this all works.
