7.1 update drains battery on iPhone 4, can I revert to previous version?

Ever since I updated to IOS 7.1 (I can't find the version number on the iPhone itself) like many users, my battery no longer lasts 3 days, but drains at about 3%/minute, even with all the apps and location services switched off. Can I revert to the previous version please? And, if so, how? Thank you for allowing me to use the phone without switching the entire phone off 99% of the time! Thank you for any assistance that you can give me on this very frustrating problem, over which Apple is sure to lose customers!

yes there is a way. i figured it out a few days ago. first download the firmware 4.0 from a site. then go into itunes with your phone plugged in AND ON (do NOT put in recovery mode).. hit shift, update. find the 4.0 firmware you just downloaded. it will take a minute but you will downgrade right back down to 4.0. when it completes, a screen should pop up saying there is a new update available (4.0.1) & asking if you want to update. CLICK CANCEL. then you're done! if you want to make sure it worked, go to your phone--go to settings-about-software. it should say 4.0. hope i helped

IOS 5.01 update draining battery on iPhone 4

I have an iPhone 4 and ran the update to iOS 5 on Saturday. I regret doing this now. Before the update I had great battery life. But since Saturday my battery needs to be charged multiple times in a day through normal use. In 1.5 hours of unplugging my iPhone from the charger, my battery drained to 88%. In the last 10 minutes it took to log in & post a couple comments, my battery has now drained to 83%! In 10 minutes!! That is an embarrassment guys. Please fix this ASAP!

I had both the synching "waiting to copy problem" and ios 5.01 battery problem. Eg: phone was at 100% at 11pm by morning it was stone dead. Both issues are resoluved now.
1: "Wainting to sync" issues was resolved by upgrading iTunes to 5.01 (windows 7 64 bit)
2: Battery problem was resolved by backing up my phone and finally seeing it complete fully. Then resetting the phone to factory and restoring the phone from backup
In the middle of the restore I had a time out error, I unplugged the phone, restarted itunes, started the restore again and now everything seems fine.
The phone has been at 100% for over an hour now.
I hope this helps.

You can either use Apple’s recycling program, or sell it to someone other than Apple. Apple won’t do actual trade-ins for products which are more than 14 days old.

IOS 8 SEVERELY draining battery on iPhone 5

Is there any way to fix it??
My Home/Lock screen racks up 47% of my battery usage since updating, while the background/app refresh, location services, and other features that drained battery in iOS 7 are turned off.
My battery has gone down by 5% within just 10 minutes of my phone sitting there, having absolutely nothing done to it.
Whenever I click the home button after about a minute or so, it goes down by a percent (sometimes two).
So my phone isn't even going to last me an hour of usage after this "upgrade"?

As much as I love getting a new gadget, I respect our environment more. So I'm holding on to my iPhone 5, 16GB because it's worked so well for the last 2 years and is still going strong. I charge it every night and at the end of the day I usually have 20% battery left. But that was before the iOS 8.0.2 update...
Now my phone lasts 4 hours and over heats. It died 3 times yesterday with normal use. The only variable is iOS 8.0.2
I looked up forums and found "tips" that are more like work-arounds. I tried resetting all settings which didn't work. All it did was give me annoying settings like 2 reminders for one SMS, location services off, and I lost my favourite lock screen photo of my two children (even though it said "no data or media will be lost" ).
I checked the settings for apps that are using most battery. Phone and lock screen are the top two. Lock screen?? Seriously??
I remembered that when I use GPS apps (ie. TomTom or Google Maps), the phone (just feels like any other "phone" now without the "i") would heat up in the same way it does now. So I snooped and found a little switch hidden deep, deep down in Settings > Privacy > Location Services > System Services (scrolled down to the very, very bottom) and there was a switch for Status Bar Icon. I turned this ON and paid attention. It would turn on by itself on the lock screen. I thought that maybe Siri is using it? So I went into Settings > Privacy > Location Services and turned Siri's location access OFF.
The phone cooled down almost instantly. I'm charging it now and will update below on how I go, if anyone's interested...
Let me know how you go with this?

Hotmail account drains Battery on iphone - process loops indefinately

Apparently the migration from Hotmail to Outlook by Microsoft, which took place during the last 2 months has created an incompatibility issue causing some iphone process to be looping indefinitly thus using up battery.
My battery on my iphone 4 was draining in a few hours and turning hot while not doing anything (idling).
I downloaded lAssistant (with an L not an i) and noticed that before i deleted my hotmail account, the activity of the CPU while my iphone 4 was not doing anything, was 35-40% while AFTER i deleted my hotmail account the activity dropped to 4% and the battery returned tom normal drain.
My Iphone 4 returned to normal operation after
1. removing my Hotmail account from settings->mail,contacts->accounts->(choose hotmail account) Delete Account,
2. turning off my iphone 4
3. turning on my iphone 4
4. Re-adding my Hotmail account
The battery has STOPPED draining and getting hot.
Now if this was done by Microsoft on purpuse or not is another issue........ Apple should fix this bug immediatelly.

What bug? There was an issue in the setup of the account or possibly an email stuck in the out of constantly trying to send. Removing and re-adding the account resolved the issue.
Sorry, but there is no issue. Therefore nothing for Apple to fix.

Does keeping hotspot on drain battery in iPhone 5?

Does keeping the hotspot on drain the battery in iPhone 5 if it is not being used by another device?

Not significantly.

Drained battery with iPhone 3G 3.0 upgrade

I loaded the new 3.0 software a few days ago with no problems. Today I found that my "turned off/ idle" phone in my pocket had gone to the new Apple recorder program and has been recording for 58 minutes by the time I discovered it. So unknown if this will be a source of battery drain by a program starting on its own (buggy?).

mine lasts a lot.
this is pretty much the daily use of my iPhone3G using 3.0 for a week.
i work from 7am to 4PM, one hour break time in that timeline , its on standby for 8 hours , on break time i pretty much make heavy use of Youtube , Safari and Mail among other Apps like IM+ and sometimes some games, after my work day i still have almost 50% of battery left.
my settings
Push is set to manual
Notifications are On and have 4 apps on it
the internet connection is always 3G
so my guess is that you guys do heavy use of your phones all day or maybe you guys are leaving the Safari , Mail and IPod apps running in the background.
test this and see if your battery lasts longer.
after every use of Safari , Mail or IPod before putting your Phone into standby do this, open safari, then press and hold the top button until you see the slide to power off option, release that button and now hold down home button (square) , after 6 seconds it will return to the home screen and Safari will be closed now ,do the same for Mail and IPod, open mail press top button until off slide , hold home for 6 seconds , then open Mail , hold top button until off slide then home for 6 seconds, now apps that don't shutdown like Safari , Mail and IPod will shutdown and the phone will use less battery while on standby. if you open them again they will again remain open and drain battery.
there was a function on 3.0 when it got announced that it would close every app to save battery, people complained about it, apple listened and removed that function. now only Safari ,Mail and IPod apps stay processing and wasting battery in the background.

TS3258 I get error message -42408 when trying to download itunes update 11.0.2 and thus can not upgrade to latest version. What should I do?

I get error message -42408 when trying to download itunes update 11.0.2 and I therefore can not update to that latest version. What can I do?

Hey there davidgor2!
I have found an article that should help you resolve this issue with updating your iTunes. The article can be found here:
iTunes: Advanced iTunes Store troubleshooting
http://support.apple.com/kb/TS3297
and the specific part of the article you will want to look at first is right here:
"Error 42023" through "Error 42408"
These alerts might occur when trying to authorize iTunes or during launch when iTunes checks for authorization information.
Install the latest iTunes from apple.com/itunes/download/
Remove the SC Info folder.
If that does not resolve the issue, see iTunes: "Error 42408" or "Error 42404" after upgrading to iTunes 9.0.3.
Thanks for using the Apple Support Communities!

IBooks 3.1-all PDF books in my Collections disappear after updating to 3.1 on iPad 4 ios 6.1.2! How do I recover or revert to previous version? (Can one do selective restore of back on iTunes?)

Just updated iBooks app on my iPad 4 to ver 3.1. Upon launching iBooks 3.1 briefly saw my PDF books on my Collections bookshelves then they suddenly disappeared! (Purchased Books are still present)
How do I recover all my PDF titles in my Collections?
Can one revert to the previous version of iBooks?
How can one do a selective restore from iTunes backup of iPad on PC? (Don't have iBooks running on Mac/PC)

You've tried tapping on the Collections button at the top of the bookshelf to see if they are in a different collection ? If not then do you have a copy of them in the Books part of your computer's iTunes library (though PDFs aren't iTunes purchases, if you've done 'transfer purchases' whilst they were on the iPad then they should have copied over) ?
ibooks and PDFs aren't included in a device's backup, so if they aren't in your computer's iTunes library and/or you don't have your own backup copy of them then they won't be on your computer (for info there isn't an iBooks app/program for a Mac or PC).

I don t succed in updating itunes at the newest version because pc can t remove the previous version

i don t succed in updating itunes at the newest version because my pc cannot uninstall the previous version

Is that a:
The older version of iTunes cannot be removed. Contact your technical support group.
... error message?
If so:
(1) Download the Windows Installer CleanUp utility installer file (msicuu2.exe) from the following Major Geeks page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):
http://majorgeeks.com/download.php?det=4459
(2) Doubleclick the msicuu2.exe file and follow the prompts to install the Windows Installer CleanUp utility. (If you're on a Windows Vista or Windows 7 system and you get a Code 800A0046 error message when doubleclicking the msicuu2.exe file, try instead right-clicking on the msicuu2.exe file and selecting "Run as administrator".)
(3) In your Start menu click All Programs and then click Windows Install Clean Up. The Windows Installer CleanUp utility window appears, listing software that is currently installed on your computer.
(4) In the list of programs that appears in CleanUp, select any iTunes entries and click "Remove", as per the following screenshot:
(5) Quit out of CleanUp, restart the PC and try another iTunes install. Does it go through properly this time?

Revert to previous version after update

How do I revert iTunes to a previous version after an update; I don't like the fact that they changed it to strictly a player-only and one cannot access things like the Radio stations, etc. any more.

I'm looking for a way to go back as well. With each new rev, iTunes becomes ever more nebulous.
I still burn CDs...but the new version makes this difficult.
In past versions of iTunes, the total time of a playlist was shown in the Status Bar and could be toggled from a rounded total (e.g."1.2 Hours") to an exact total (e.g. "1:20:23")
In 'the new itunes', the total time length of playlists seems permanently fixed ion the broad value only. (e.g. 1.2 hours).
This is terribly inconvenient if one is going to be burning a Playlist to a CD or DVD-A. Where 79 minutes would fit on a CD, 81 minutes will not.....yet 'the new itunes' will show both only as "1.2 Hours". Very inconvenient if one is now to be forced to manually add track times together in order to decide if a playlist will fit or not.
How do I get 'the new itunes' to show me a more useful total? Or has Apple now decided that we aren't going to burn CDs any longer? (Surely, by now you can figure out on your own what my opinion of that might be.)
