Q: iPhone 4s Battery Life?

news news news... i bought iphone 4s 32gb withe on 14th oct, my battery lasted from 6 to maximum 10 hours... from the first chargin battery lastin increase... but never more than 10 hours... today i went to apple store customer service and the changed it with a new one... this is my first chargin and the battery no is 34% and usage is 5.28 h stnad-by 10.53h... sure it is not enough but i feel like very optimistic!!

How do I unsubscribe from the email feed? I turned off every **** setting they have, and I'm being flooded with emails I DON'T NEED OR WANT TO READ!

there's a link on the highest part of the page, on the right... "stop email notifications".. dont worry just click it!

You are obviously one who has nothing better to do than to criticize rather than help. I have been on the internet for the past 13 days, trying to figure out what is going on with this phone.  I have been waiting for it for over 4 years now, as I did not want to change providers.  Just because I didn't post chapter and verse to you on my first post doesn't mean anything except that I didn't post it.  Crawl back into your little hole if you are only here to **** people off.

I am not sure how one replies usefully in a 129 page thread, but I have "fixed" my iPad2 and iPhone4S by doing the following - my iPhone4 did not have the battery drain problem after a normal update, btw/fwiw.

For the iPad2 and iPhone4S, I tried all the various tweaks and resets, etc., with no success.  What I then did was to do a DFU restore as a NEW DEVICE and manually "rebuild" the device app by app.  They both work perfectly now with normal iOS4.x battery drain (ok, the iP4S is a little higher than the iP4, but not much).  Both are VZW 3G models, btw.  What I did before I nuked the device was to make screenshots of each page and each folder so that I knew what I wanted to reinstall, what page to reinstall it on, and how to group the files. 

Was it a PITA?  No, it was a PITFA.  Actually, a BFPITFA. 

Did it work?  Yes, on both the iPad2 and the iPhone4S. 

OK.  I had my 4S at 100% the other night so I put it in airplane mode then went to bed.  When I woke up 7 hours later, my battery was completely depleted... YES while in airplane mode!  This has now happened on 2 separate occasions.  I have done the usual wipe the phone, setup as new, etc. and nothing has really worked.

Other odd things that happen is my 4S will get EXTREMELY hot at times and I can basically watch the battery percentage just drain down.  The other day, my 4S went from 100% to 75% in 1 hour and during this time, the phone would get really hot at different intervals, almost as if the processor was running at 100% utilization.

I did try a trick mentioned in another thread of deleting my exchange account, rebooting the 4S, then adding the exchange account back to the phone.  Mystically and unexplained, this has seemed to have helped and has increased my battery life and my 4S has now been less prone to getting unusually hot throughout the day.  It still does get hot, but not as much as prior to deleting and readding my exchange account.

Ok what is going on with this battery thing. I just went an picked up a a new 64g 4s, after doing a full restore, following the blogs about notifications settings and such, and wouldn't you know it. After I left the store, got to my car, lost 3% or battery power. Should I take it back again? So confused with hardware/software issue, don't wanna be stuck w/ this phone for the duration of my contract with AT&T

Just out of curiosity in case time ends up not being on my side waiting for this fix....how long do we have to return our iPhones for another phone or refund (I'm on Verizon if that matters)?

I almost never use my phone for actual calls, but am also having problems with battery life. If I use an app for maybe 15 minutes, the drop is really alarming. By the end of a 9 hour work day, without making any calls at all and using the phone only to do some light web surfing or texting once in a while - it has lost 30% of its charge.

I previously had the earliest gen iPhone, the 3G, and I could go 3 days or longer without recharging. Now I have to plug my iPhone 4S in every night. I love the phone otherwise, but the battery life issue is a real problem.

So, I turned off Time Zone setting and wala! No more massive battery drain.

It appears I was caught between two towers and I did not have the ring that controls them all.

Apple may want to track down Gandalf to help this.

The Verizon refund policy is 30 days with a 15% restocking fee. You may be able to get a manager to waive that if you explain the issue and purchase another phone. Good luck!

Okay,  Just got the iPhone 4s.  Was fully charged using the wall charger.  Once I unplugged it from the wall at 7:00 AM and the battery dropped 5% instantly,  I let it sit on the desk all day and by 7:00 PM it had shut down.  That was all standby time.  I've also noticed the signal strength is not the same as the iPhone 4.  Where it sets on the desk the iPhone 4 would have 3 bars, the iPhone 4s gets only 1 in the same spot.  Another strange thing I noticed was duplicate entries in my contact list.  In and effort to fix that I would delete one and that in returned removed both of them along with removing it from the cloud and the other devices.  Now I have to recreate the contact.     So far I'm disappointed and thinking of switching back to the origial iPhone 4, I hope Apple finds the problem and comes out with a fix soon. 

Apple Dev here. Sounds like your iPhone is heating up, propably because of processor usage. That is pretty weird, because it has certain restrictions to the CPU usage; some processing power and 10mb of ram reserved for system. Usually the system (iOS) still activates these blockages on the first boot. Sounds like these blockages are off, and the CPU is being used more than the restrictions would allow. The restrictions are in place, to avoid such heatups from "over usage". I have an iPhone 4S too, and I am currently troubleshooting for errors. It still seems like they are on. I will post my findings here.

I've been following this discussion on a couple of the other discussion boards where users are dealing with this same issue. Two of the things that have been reported as causing a significant drain have been email notifications from a Microsoft Exchange server - which seems to be creating some kind of a continuous loop that is keeping the processor constantly running and generating heat as well as sucking power - AND syncing with iCloud - so far no technical reason given for this.

Some users have reported syncing there phone with iTunes and then restoring it from iTunes as a NEW phone and then restoring their data has helped. Others have noted that turning off Push notifications has helped, although this seems to again be primarily for those who are using an Exchange email server.

A few other points users have noted...using Siri has NOT made any difference, and WiFi vs 3G hasn't made any difference in their test results. I can not confirm any of these reports as I have not yet run my own independent tests, however as near as I can tell, I am not affected by the problem. I am syncing to a Yahoo mail account and am not using iCloud in my configuration.

It also bears noting that the 4s is my first iPhone so I don't have any personal experience with previous versions to compare to, but overall my battery life seems adequate. It is certainly MUCH better than my previous Droid Charge that ran on the Verizon 4G network. 4G kills your battery in a REAL hurry...and that is what ultimately prompted me to drop Android and make the move to iOS! I am totally thrilled with the iOS experience so far and am kicking myself for not having made this move LONG before now!

I will post back if I either hear other useful information or have any relevant test results that may be of use.

I believe you have 14 days... Thats why I havent gotten one yet. Thats right....THE ONE AND ONLY THING STOPPING ME FROM GOING AND GETTING AN IPHONE IS THIS ISSUE. I honestly planned on getting one TODAY. please Apple, fix this! :)
