Apple also contacted me and had me sent battery log file too...
Well, this is called damage control....
I am not sure what they are going to do?!It has been weeks since the updates. When I asked them, they didn't and couldn't give me straight answer when this is going to be fixed. Basically, they are just getting data. I think Apple this time is really in big trouble.. By the way, upgrading should be better, not worse, turning off features defeats the purpose of upgrade. (Well, they should mention this new feature in one of their new IOS 6 features.. It is called Battery quick draining feature!.... no other phones can beat that!)
Because of IOS6, I start thinking of getting Android phone instead in my next cell phone (i am on iphone 4 now) upgrade.. I will do more research on Android phone now........... (like compatible apps I used in iphone)
Sorry, Apple, I don't think I will upgrade my iphone to iphone 5. You had better act quick or you will lose one loyal customer very soon!
To downgrade to iOS 5.1.1 your iPhone would have needed to be jailbroken on the 5.1.1 firmware to have access to the SHSH blobs for 5.1.1 (as Apple has stopped signing this firmware).
It's the most annoying thing I find with Apple. They should, at least, still be signing the previous iOS to allow customers to roll back in the event they are experiencing problems with the newest iOS release on their devices. It is the sole reason I jailbreak my iOS devices; to have that peace of mind, that safety net, to roll back my devices to a more stable iOS if needed. And in this caes, it's definitely needed!
I too am experiencing the same exact thing. I am so disappointed and hope Apple fixes this quickly. I can't believe there is no way to roll back to the previous ios until the issue is fixed and extremly hard to believe that this wasn't an issue during testing the new system. I don't know if affects ATT or Verizon folks any differently or not. Good luck everyone
Same as above: I basically am running a portable phone with contacts after turning EVERYTHING else on my 4S off, and the battery is still losing 60-70% in a matter of hours. I did a Factory Restore last night that did nothing to help the battery life. Battery life was fine until I upgraded. I can't really rely on teh iPhone anymore as an alarm or for important info because of the chance it will die. Unacceptable.
I'm hoping to try this tomorrow and go down to my local apple store to see about getting this resolved. I have extensive screenshots and am hoping they understand once I discuss the problem with them. I'm tired of having a phone that I now have to charge twice a day to make it through a 16 hour day. And I also hate how my phone is constantly hot and in use. Best of luck to everyone else as this is one terrible situation. Seriously even considering selling my iPhone and buying an android phone.
Are any of you also seeing excessive cellular data usage? I recall from my testing before rolling back to 5.1.1 my 4S was also gobbling up quite a bit of my data plan. I had never come close to exceeding my 2GB plan with ATT before - after rolling back to 5.1.1, I received an automated alert from ATT the next day that I was about 500MB away from hitting 2GB. Craziness.
Just trying to narrow it down a bit. I still believe that the proximity sensor / light sensor is playing into the battery drain. After reading about the excessive data hits some were seeing, I wouldn't be shocked to learn that this is also a factor in the iOS 6 battery drain mystery.
Its because Facebook Integration in iOS has bugs and requires fixes. Facebook Integration in iOS consumes RAM and slows down everything due to which the Apps keep closing and Wifi is unable to work under the extreme conditions the way it normally works. I was having Slow or No Wifi connectivity, Apps Crash and Decreased battery life. I browsed through this forum and found the solution that Facebook Integration deletion is the only answer to the solution of all these problems.
well I was advised by apple telephone support to go to a 'genius' and change my handset (again) because of battery life issues.
For some reason this time I was treated like an idiot by the genuis. Not only was she trying to multi-task and see another customer at the same time leaving me standing there waiting for about 20mins, she started to tell me that this battery life is 'normal'
I showed her screenshots - apparently because I had low signal this caused the battery to drain 1% every minute.
Also apparently you have to charge your phone twice a day using it 'normally'. I told her this was nonsense and there's no such trouble with 5.1.
Then she showed me her iphone - and it was at 60% and been on all day. I pointed out that my phone would be dead by now. She also had a bloody Mophie battery case on her phone!
She then told me she wanted to do the iOD6 update in store because 'she didn't trust my iTunes'. I wanted to keep it 5.1 but I also want to prove it's not actually my fault the battery life is shot.
Anyway - this experience was a lot more prolonged than my other visits to the genius bar regarding this battery issue.
Her solution was to wait for a fix because I was still in warranty. I told her I wanted a replacement now.
So - the excuses I heard at the Apple store (after an hour in there) were:
I'm using the phone too much
The battery is normal and it needs to be charged twice a day (from a full overnight charge)
The battery drop is normal
I used push email
I am in low signal areas sometimes and this causes massive loss in battery.
While I was waiting 2 other people appeared with battery life issues.
I have now a brand new 4s and I have charged it overnight. There are NO apps on the phone - and I've not even added icloud. Its been used for 7 mins and on standby for 80mins. It has dropped 2%. Not sure if this is usual anymore.
I am going to monitor it and then slowly switch things back on. At the moment I have a phone I can text from - which is like my Nokia 5.1 in the box in my cupboard from 15 years ago.
I've an iPhone 5 and notice that the battery life was too bad the first days.
I was wondering what "features" makes this battery drain and found that, the IR sensor is always ON when I switch on the display doesn't matter if Siri was on or off and if the fearure "rise to talk" was on or off.
But I've found some workarounds that for now, shows to work and improve battery life, for instance my phone was now 50% battery from a full charge, with 4h26m of usage and 19h44m of standby mode (I use my phone with the alarm to wake up in the morning and in that situation the phone is in "plane mode")
The workarounds was to switch of the automatic control of the display light, and switch off the automatic adjust of the hour and day.
Hope it helps someone till we're waiting for the update that solves that issues. I'm very disappointing with this situation
And also aplogize for my bad english
Thanks for that post Kewong - My 4S was behaving normally when in standby mode (normal battery drain), but within 2 minutes of waking it and using the phone it became really hot and the battery began to drain very quickly (10% in 15 minutes). Seems that getting rid of the asst touch button has really helped to fix this. Anyone experiencing fast battery drain and excessive heat ONLY when the phone is active and you have asst. touch on try switching off the asst. touch.
Hi all -
Here is an update on my results from changing my exchange account to "fetch" from "push" - blog dated: 10.03.3012 @ 2:13pm ==>
With no other changes other than changing my exchange account to "fetch" from "push" my battery has been back to when I was on IOS 5.1 or even better - it has been 4 days now and battery life is stable - back to normal usage of phone - web browsing, games, texting, emails from gmail and exchange, facebook, instagram etc.
Last night battery was at 65% - did not do an overnight charge - woke up this morning @ 7AM- checked emails and facebook - battery is at 64%.
Hopefully there is a permanent fix from Apple but for now this change from "push" to "fetch" (knock on wood) has been good to me.
My biggest remaining culprit appears to be safari. It goes through percent points like minutes it seems. I don't remember it being such a battery hog before. I turned off Safari iCloud and still drains real fast I think.
I would like to change my default browser to something less bloated if this persists after the .1 update.
They have enough idea of some things causing the drain, push mail, low signal, Safari, iCloud, asst touch, Facebook, iTunesMatch caching instead of permanent downloads when you choose to download (not 100% on that one), etc. by drain I don't mean the concept that phone use and features use battery. Every person familiar with their iPhones in the past saying battery is way worse understands that I think. I mean things with bugs that in some situations now use extreme battery loss like people may make fun of you for using iPhone loss.
It's a smart phone and should be able to manage those things better than it does, especially those things that had much better battery life on iOS5. People are calling it worse who used push mail before, so iOS6 just needs to do it as intelligently as iOS5. iOS 6 needs to know if it can't connect to a pushed mail, perpetually retrying every second in the background is wasteful.
Even if they can't fix 100% of issues it seems like they know enough, that the .1 should improve a lot. Maybe this will become the most battery efficient smartphone OS, with easy options like notebook type battery profiles and presets to easily move between all these tedious adjustments when we need extra power.
I like iOS and hope this huge mistake makes it even better, if Apple acknowledges and learns better power management with the new features and whatever bug throttles things, instead of spinning it as "the new normal".
I can dream :)
