Iphone 4s Battery life WORSE with upgrade. Anyone else seeing same?

Problem solved!

I'm encountering exactly the same problem. My iPhone 4 is 10 months old, and in the last fornight the battery life has reduced dramatically, from 100% to 0% in 5 hours. I did the 5.0.1 upgrade.. with no change, Apple kindly replaced the battery..no change. Apple also advised that I have a processor actively operating whilst the phone is idle, and should do a complete restore, but having read what I have, I've got the sense that this will not do the job either.

Any ideas ??

I have a service call from MAC Tuesday morning. Keep you up to date as my results. I will NOT. Be happy if they offer a refurbished. I bought new, I want new.

i have the same problem with iphone 4.

there wasn't any problem with IOS 5.0.

after updating to IOS 5.0.1 - the battery life WORSE with upgrade.

I had similar probs went to a reset I have posted cured my problems good luck

Hi I am on my second new 4s both have had problems and it wes mutsch worse after the update i have just done what i call a double instal the results are astouding good luck

I have what may be an odd question for all of you still experiencing battery issues... I just had my last iPhone 4S swapped out because of static in the earpiece. The static noise is not an in-call thing, it's actually coming from the circuit board inside the 4S. If you hold the back of the iPhone 4S (apple logo area) to your ear while your phone is pulling 3G data, the buzzing is loud and clear. I also had a quickly draining battery on that phone which iOS 5.0.1 didn't do much to fix.

My replacement unit has no static buzzing noise and the battery appears to last longer. I have had my phone unplugged for the last 2 hours, sent and received about 4 text messages and had about the same number of emails pushed to me via iCloud. I also had a 7 minute phone call. Battery is still showing 100%. On my previous 4S w/ static issue, you could see the percentage drop even while sending/receiving text messages.

I am of the opinion that the battery drain and static/buzzing issues are related. The buzzing only happens when on 3G, and there may be unusually high voltage drain on those particular units during 3G activity.

Movanoman...

What specifically did you do? Set up as new and then restore from a backup?

I have the same problem battery was "ok" with ios 5 after update battery got worse it drains while in stand by. I fully charge it before going to sleep wake up and check my phone battery life down to 85%

So after a weekend where the phone shutdown twice for lack of battery after being on standby for 5 hours each time, I looked around here in the forums and did the resetting, reinstalling software from tunes, turning off location services, etc, NO CHANGE IN RESULTS - I am losing 20% of battery every hour with phone unused and sitting in standby mode.

I called apple this morning, they had me shut some more things off and then booked me a Genius Bar appointment for the 5th avenue store in NYC; I cut out for early lunch - walk 20 minutes to the store only to find out that there is a 45minute backlog on appointments, and for a battery issue there is not much they can do beyond the resets and shutdowns I am already reading about here.

Interestingly 1) my battery life was fine before OS 5.0.1 and became unacceptable post install; and 2) my daughter has the same phone, hers 16gb, mine 32gb, and she has no battery life issues, pre, or post 5.0.1. They one big difference between daughter and I is that I am on Outlook Exchange for work and she is not. These phones MUST be made to work in a business environment (outlook exchange and ability to push messages) with some reasonable battery life (I've got no problem having to charge every night) or they are useless bricks.

If Apple can't sort this out by Friday I am back to blackberry, or switch to Android as I can't be unconnected every 5 hours, or forced to stay on a phone charger.

Outlook Exchange has always been a battery drain in every version of iOS. Have you used the same Exchange account on a previous iPhone model? If so, how were your results? I would suggest you take the unit in for an exchange. Also, are you experiencing any static or buzzing noises from the earpiece? Just curious. I exchanged my 4S on Sunday and that solved all battery and buzzing/static issues. I restored from an earlier backup, so no clean install required. I have a feeling the buzzing/static is related to the battery issue.

I set up as new a New I phone in case any problems remained I opend safari to see the phone worked then went then went back to erase all content and setings cleared the phone down this time restored form icloud my back up and re loaded all aps. all now ok good luck movanoman.

movanoman,

I am glad the process worked for you.

I don't know why people are so hesitant to do a "Restore as a new phone" or the manner you used. Nothing is lost except the time it takes to do it... 30 minutes tops.

I did the DFU mode then restore as a new phone which gives me the opertunity to restore all my apps, notes, mail, etc. I did not due a complete restore (probably faster) because I didn't want to bring back any problems that may still exist in the "Backup" that was made prior to the "Restore as new". Call me paranoid.

This worked on my iPhone 4 and now again on my iPhone 4S. I don't know what the problem is that causes this battery problem but it seems to be more related to however Apples implements it's updates than the actual update itself... Any way it has worked for me on two completely different model iPhones.

My current Usage (starting from 100%) is:

Battery @ 61%

Usage: 2 Hours 47 Minutes ( [WiFi] browsing, checking the weather, YP yellow pages and a couple of 2 meg picture emails)

Standby: 1 Day 14 Hours

Cell Usage 35 minutes (3G phone conversation).

I don't know if the above battery consumption is the best the 4S can do but it is a whole lot better than before!!! 🙂

Email most likely draining battery. I also had severe battery drain with the battery heating up after update last Thursday. I usually don't post, but there was a simple fix for me. I read over numerous forums and tried almost everything except a full restore with no luck, until I found deleting my email accounts and then adding them back worked. Within 20 minutes, my phone cooled down and battery life was normal again. I'm thinking it had something to do with my Microsft Exchange account, but it works fine now. I've had my iPhone 4 since March with no problems until last week. If you have an Exchange account, try deleting it and add it back on before anything else to see if this works for you.

HolmanGT I already tried that and it didn't make the slightest difference
