Q: iPhone 4S 5.0.1 Update Improves Battery w/ Settings Reset

I just stumbled upon this thread and comtemplating whether or not I should do this reset now, or wait until Apple issues a new update, or a set of instructions like the ones davidch outlined (well done davidch by the way for discovering this fix).  If I do the reset, does it matter what settings are on the phone when I do the 5.0.1 update and then subsequent reset (ie time settings on/off, notifications on/off etc)?  I assume not since they'll all get reset anyway.  Also, does it matter what the battery life is at when I do the reset?  Should I aim to have it closer to 100% or closer to like 20% when I start?

My 4S battery seems to have fixed as well but i think it may be because the other phone i had was defective. it would get warm abd cause the battery to drain. BUT my replacement 4S seems to be holding up well. right now i have 15 hrs standby and 1 hr 30 mins of usage and 71% battery.. dk if thats good or not.. i dont really get tons of calls or really use it tons. Is that good or bad?

After starting my phone as a new device and syncing from the cloud All I lost was my notebook (I don't know if it's just because I didn't have it turned on to sync) it took me about 5 minutes to retype my old notes back in.  And my personalized ringtones per person, and some sound and screen settings. Calendar, contacts, texts, emails, pictures, and vms were all there after I went into each app. It took a few minutes for the text numbers to associate with name contacts. It was not a biggie and took a short time.

from my experience i think its the 3g, because when im at home where there always a full bar in my signal, i'm loosing a 1% percent every 3 hrs on a standby mode, all notification are off, wifi=off, siri=on, location=off, but when im at the office where my signal tend to fluctuate every so often im loosing about 4% percent every hour with the same status on standby mode, why did they disable the button for 3g on and off unlike iphone 4 it has an option if you want to use 3g or not, hoping they will bring back the option for 3g usage

Same problem here!

@davidch .... ur thread is hope for me at last, in some part here in india, there is not strong bandwidth as there in US and all. 3G is available in selected cities in india. in this senario battery drain becomes more seveire,as it many times in searching mode..

I own iphone 4, updated to ios 5, now scared to update to 5.0.1. , again i am lost in all thease blogs posted.

i mean sequence of activiies to be done.. if possible snd me this sequesnce on my email id. vishwanath.retharekar at gmail dot com , i will be much greatful, i own macbook pro, is conecting iphone to my mac, again reset all settings suggested by you?

i hohe you will help. i asked to email because i am not sure that because of weak network i will be able to access and find this thread again.

Turn off cellular data then.  Turning this off shuts down the data (radio).  It does not effect cell reception. You wont be able to access data for any function or app that requires it, but you can still use the phone.  If you have visual voicemail it will be deactivated though, but you can still dial into your voicemail using the phone keypad. 

Turning off cellular data on the 4s will turn off ALL forms of data communication (3G, 2G-Edge, GPS, etc).  The only difference between the iPhone 4 and 4s is that the 4 had separate controls for cellular data and 3G.  If you wanted to have data but did not want to use 3G because your battery life blows, you turn "off" the 3G toggle and leave the cellular data toggle "on" (so you end up using Edge or 2G, GPS, etc). 

I would say that something is definitely causing sflomenb to drain faster than normal.  My stats right now are:

Battery = 96%

Standby = 7 hrs 18 mins

Usage = 19 mins

So about 0.54% per hour of battery drain.

Hi there,

 

Im having problems with my iphone 4s battery, just done get it at all!

 

At 12.43pm today i checked my usage etc and it was the below -

Usage - 2hrs and 4mins

Standby - 3hrs and 57 mins

Battery - 69%

 

If you had those times together, it adds up to 6hrs and 1min.

 

I only took my phone off charge this morning at 8.43am so it was 100% then! That is only 4 hours between 8.43am and 12.43pm! know i most definitely have not used 2hrs and 4mins of usage, im at work!

 

Help!

Your standby time (total time the phone has been on) includes the usage time (2hrs 41mins).  You don't have a problem.  Your phone is draining at a rate of 7.8% per hour, which is within specs for the iPhone 4s.

It seems I'm having some real problems also.

Usage- 3hrs 32min

Standby- 6hrs 47min

And my battery is 35%

Hey guys. My stats as of 4:34 pm:

Battery: 66%

Usage: 1 hour, 22 minuets

Standby: 9 hours, 24 minuets

Still bad

I broke down. I'm at 33% with 3 hrs usage and 8 standby. That's my average with my last iPhone 4.  My phone gets really warm with under a minute of use. Called Apple. I get a "remade" one tomorrow. I kind of don't like that because my phone is new. They said that the remade (not refurbished) ones are actually tested so they all work. Ok I guess...maybe I should've waited for 5.0.2? The girl at Apple said she has seen problems with both software and hardware on the new 4s which is causing battery drain. This is when she is notified on her follow ups. My point is, they are seeing problems with both issues, not just a battery recall or software solution. Good luck.
