I Have the same issue on a brand new iPad mini 2. My battery is only lasting up to 5 hours. I went on chat with Apple last night and they said my battery is fine and its a Safari issue. I'm literally losing 1% every 3-4 minutes. I tried recalibrating my battery, signing out of iCloud, shutting off all locations, turning off background app refresh, restoring network settings, restoring all, and finally restoring from iTunes with no luck. This is just awful. I got this iPad so I could use it on my long flight for a trip I have coming up, and unfortunately, it's not going to last that long, plus I'm concerned about how many times i will be recharging my battery because of this since battery's do have a life cycle dependent on the number of charges. This is frustrating and needs to be fixed ASAP and addressed by Apple.
By the way, Apple told me to bring my device to the Apple Store because it's still under warranty. That's great and all, but I'm going to waste my time if there is no fix for this issue.
Ok so you want Apple to address the problem, but yet you don't want to take it to them just in case they can't fix it? What if they can fix it? Complaining here certainly won't fix it.

After latest Software Update my iMac goes to a prohibition sign on startup

iMac Info:
24" Intel Core 2 Duo, 2.66Ghz, 4GB Ram, yadda yadda
The latest software update notice I received informed me the following new software was available:
* Performance Update (version 1.0)
* iMovie Update (version 8.0.5)
I told it to install the updates, after which the computer had to be restarted. Upon restart the computer seems to be restarting normally, ie: the bell tolls and the Apple symbol shows above the spinning icon. But after what seems like a very long time a "no symbol" aka "prohibition sign" takes the place of the Apple logo, and the spinning icon remains. Nothing else happens. To see the screen I'm referring to check this image:
http://donnypauling.com/images/prohibitionsign.jpg
*Here's what I have done so far:*
* I called expert case support and we tried a few things. The guy I talked to decided that I needed to use my snow leopard disk to use time machine to restore my system to the way it was before the software updates. He figured something must have been corrupted in the software update. I couldn't find my Snow Leopard disk so he emailed me instructions to follow when I finally found it.
* After finally finding the disk I followed his instructions and restored my system to an October 8th backup.
* Upon restart all was supposed to be well. That didn't happen. The same problem persists.
* Support is now closed, so here I am searching these discussion forums. One thread mentioned a similar problem and it was recommended that the person start in safe mode and repair disk permissions. Sure enough, my iMac starts in Safe Mode. I repaired disk permissions. Restarted the iMac. The same problem still exists.
Now what?

I have had similar issues since upgrading to Snow Leopard. The first time, I took my MacBook to be checked and the tech said it booted up fine under another startup disk. Since it's under warranty, they just reloaded the original system (Leopard) and I needed to rely on a time machine backup. Now, after the latest software update from Apple, I had the same problem, and am restoring from the latest Time Machine backup.
Does anyone know if this is a systemic problem? Any tips on preventing a repeat the next time I need to update my system software?
Thanks.

"The Selected Video could not be played" error after latest software update

After the latest software update for the Apple TV I've come across an interesting problem that's driving me crazy.
In a nutshell:
- I can rent movies and watch them.
- I can watch video podcasts.
- I can watch TV shows purchased on iTunes and streamed from my mac
- I can watch TV shows ripped by myself and streamed from my mac
- I can watch movie trailers
- I can watch YouTube videos
- I can watch a movie purchased on iTunes that has been synched to the Apple TV
- I can watch a movie ripped by myself that has been synched to the Apple TV
- I CANNOT watch a movie purchased on iTunes but it's streamed from my mac
- I CANNOT watch a movie ripped by myself that is streamed from my mac
Whenever I'm trying to watch a movie streamed from the mac I get the following error message:
"The selected video could not be played. The format was not recognized"
These are movies I could watch perfectly well before the software update, and I could perfectly watch them streamed from the mac.
Any clues as to what could be going on? Any help or hits will be greatly appreciated.
Many Thanks,
Julian

I am having similar problems. Rolling Apple TV back to 2.0 fixes it, but then I deal with the 2.0 bugs.
Basically, I've tried this three times so far: reset back to 2.0. Resync everything I can(I have about 500gb of video which is stored on a USB drive, but I selectively sync part of my library and all my music).
I have about 40gb free on the 160gb ATV. Everything plays fine - synched music, synced video, streaming video. My types of video are:
- iTunes purchased
- Ripped using handbrake to h.264 standard stuff (plays fine on my iphone and computer)
- downloaded h.264 "ipod compatible"
- converted video using iSquint
After upgrading to 2.0.2, initially everything plays fine. But the MOMENT I sync something new to the ATV, then it all falls to crap.
- itunes purchases play fine (synced and streamed
- iSquint converted videos play fine when synced, won't stream "The selected video could not be played" bs)
- Handbrake rips can play if sync'ed, won't stream
- downloaded ipod compatible will usually play and sync.
Doesn't matter if they're movies or tv shows.
*All of these played fine before the "upgrade" (some upgrade).* After the upgrade, and after the first post-upgrade sync, it falls apart.
Talking to Apple support about this results in the usual BS. Unplug your ATV. Resync your purchases, We don't support third party software yada yada.
All I know is, Apple broke something with 2.0.2. Either something to do with a USB drive access, or something to do with one of their stupid new flags in quicktime, or whatever. It needs to be fixed.
Going back, once again, to 2.0 until this is recognized and fixed by Apple.

Safari won't load after latest software update

After the latest software update from Apple, Safari won't load. I've deleted the p.list and run OnyX to clean the system. It still won't load. This is a pain as Safari is my default browser and I have to get into Safari to change that. Has anyone else had this problem and fixed it?
Thanks!

Welcome Pauline;
Actually you can change your default browser from within Mail, just go to Mail preferences and set the default browser to whatever you want. Unless you have cloned your system (before the update)which I heartily recommend,
you may have to use Pacifist to extract Safari from
the 10.4 installation package.
Hope this helps,
Miriam

Airport Disk still broken after latest software update

http://discussions.apple.com/thread.jspa?threadID=1244463
I like how the topic above was marked as 'solved' and archived. Another Airport software has come and gone and Airport disks are still broken. Mine let me copy 74GB of data to it, but refuses to show the contents via the USB port. Anyone had any luck with this after the latest software update?

PDF won't open in iBooks after latest software update

I have a large pdf file (biology textbook) that I would read on my iPad. It worked flawlessly until the latest software update (4.3.1). Now I can only see the first page and it only shows page 1 of 1, even though it is taking up all 450MB of space. I can't see any other pages and they aren't even shown at the bottom of the screen in iBooks. I tried deleting the file from iTunes and resyncing it. I also tried a full restore of my entire iPad and that didn't work. It was working fine before the software update so I don't know what to do. Thanks

I just updated to the latest update 4.3.2 and it works fine! Apparently something in the 4.3.1 update caused it to not work.

Apple TV audio problems after latest software update

Updated my AppleTV last night with latest software update. Completly lost sound through my home theater system. Only hear audio on the TV. Anyone else having this problem? Apple TV is sure buggy...about ready to chuck it out the window!

Check your Dolby Digital settings in audio Settings.

Iphone 5s battery drains fast after ios 7.1 update.

Am I the only one who seems to be experiencing this? My iphone 5S battery seem to drain much faster than usual, and charge longer. I heard that the new update is supposed to increase battery life, and read comparison threads regarding other iphones that are capable of a much better battery life than mine.
I've had my phone for 3 months, never have dropped it once or anything of the sort, if that matters. My battery drains to 50% within an hour or so after intense use on the lowest level of brightness, and I seem to lose about 5-7 percents when on standby for 5 hours or so. Is this normal? Is it perhaps due to the fact that I am mostly using 3g, and applications that require more processing such as tumblr (graphics and gifs) as well safari? I'm just worried that my battery may be draining to quick, despite the update which's supposed to make it much better according to many people.
Thanks.

Me too.
I went from plugging in to charge at the end of the night, around 11pm, to barely getting through a workday with very light use. With less than 10 hrs of standby and maybe 30 minutes with the screen even on I am rocking 15% battery life. I'm also connected to wifi whenever at home or in the office, which accounts for over 9 hours of the standby time.
I know people are suggesting turn off features... but eff that, 5 days ago I'd get through an entire day without any issue, under much heavier useage. I don't want to have to turn on bluetooth everytime I get in my car and back off when I get out, I just want it to work when I turn the car on... I don't want to manually check for emails, I want it to tell me when an email comes.

Battery drain faster after udating to iOS 8.1.2 ( iPhone 5s A1530 16GB )

I have been wondering faster battery drain after updating to ios 8, I upgraded to iOS 8.1.2 it has been worst with this drain faster by 40% in draining, What shall i do??? I have contacted apple support and customer care i didn't get a solution. Please help??

Hi Jaberboss
I did start a similar thread on this issue myself, but seeing what I've read here I hope you're ok with me adding it here to
This one is a true case of a phone with zero potentail (electrically)
OK, I've done the rounds on this one, whereby I'm just adding to the list of complaints so that (hopefully) the powers that be, or not, in my phones case, might listen.
Since updating my just over 12 month old 5s to 8.1.2, it has turned into a bag of spanners in respect of its battery life. Its literally gone from 24 or so hours between charges to less than 8 !!
I have tried shutting all the apps down and even had it sitting in full airplane mode, where i've left it alone with the screen off, yet its dropping around 1% every 3 to 4 minutes, blinding!! Checked battery usage in settings after 30 minutes, guess what standby 29 minutes usage 1 minute.
Also tried the full restore, but to no avail, still a bag of spanners!
(slight update here) Even took the SIM out with it in airplane mode and deleted all apps and a full reboot - same thing!
Does anyone remember the good old days of a fixed land line, where the phone had to be plugged into the wall before you could actually use it? lol
Nothing like a bit of retro ay, but some how I cant see this one catching on Mr Apple. Thanks

Iphone battery draining fast after reboot

hi, my iphone battery drains completely from 100% to 0% in a few hours if I switch the phone off and turn back on. i recently found this out once after I switched off the phone.....But there is no problem (battery can last 1~2 days for normal use)if i do NOT switch off after recharge.
Is this a software issue or hardware?? Has anyone got the same problem? Thank you so much.

A couple more diagnostic tidbits.....my iPhone exhibited odd behavior after downloading the Star Gazer app from the App Store on Sunday. I activated the "arrange icon" feature to move the app icon for Star Gazer to a new position on my iPhone and after I moved it the icon for the app next to it (Weather Channel App) was absent but the label was present. When I slid my app screen back to the home screen and came back, the Weather Channel App icon was visible and the Star Gazer app was now absent but the label was present. I've also had some odd flashes of the home screen after unlocking my phone (I have it secured with a PIN to protect my data). Is this and IOS 4.1 issue?
It is not an iOS 4 issue; it is a very rare problem, and has occurred with all versions. But if you search you will see reports are in the dozens, with 100 million phones in use that's a vanishingly small number. It usually means that memory in the phone is corrupted. If rebooting the phone doesn't fix it you should restore the phone using iTunes.

17" iMac (Tiger) won't boot after latest software update

I downloaded the latest Tiger software update on my 17" Intel Core Duo iMac a couple of days ago and after I hit Restart I can't get past the grey Apple loading screen.
I've tried everything it tells me in the manual, pressing various combinations of keys as I turn the computer on, but to no avail. I also put Install Disk 1 in and tried to check hardware from that (pressing D) and tried pressing C too to boot from it, but nothing happens, just the grey apple loading screen. Of course, now the install disk is stuck in there too.
Any clues as to how I can sort this out? I'm still under AppleCare, so if worst comes to worst I'll call UK support and see what they can do, but thought I'd try everything I could at home first.
TIA.

Calendar: appointments etc. dissapeared after latest software update

Iphone 3g. After the recent software update, it now takes 10 seconds plus to go from the home page to applications--before the switch was almost instantaneos for those apps not requiring an internet connection, e.g. ipod, calendar.
Also AND MOST ANNOYING AND DANGEROUS, all my calendar postings dissappeared! I use my iphone calendar for everything--appointments, deadlines etc.--so this was devastating and personally costly!
I've checked for updated, re-synced etc. to no avail.
Help!!!!!!
Eberly

Remember the old programers' joke: IT'S NOT A BUG ITS A FEATURE?
Apparently, the latest update makes it possible to turn off your calendar and (perhaps) have several calendars (business, social, tennis, etc.) The new calendar page has an options (upper left hand corner) "calendars."
If you touch that you get a menu listing: Show all calendars--my pc and birthdays. You would think if you clicked on show all calendars you would get all calendars, but you don't--or at least I don's--you get nothing!
However, if you click on "my pc" and "birthdays" (this produces a check mark" everything comes back.
I can only guess that the first synch after the update automatically switches on "Show all .." and hence you lose all.
I can't be sure this is the full explanation, BUT IT WORKS FOR ME.

IPad 2 AND iphone 4 battery draining FAST since IOS 6 update!

I have done EVERYTHING I can think of and that has been suggested all over the World Wide Web to improve the battery life of both my iPad 2 and iPhone 4 since the IOS 6 software update. Nothing works!!!! I am leaving town in a week, and I would like my phone to be working the way it did before.
Still taking suggestions to fix this.
APPLE please do something. I am losing faith, and I am also losing my desire to buy the new iPhone 5!
APPLE PLEASE HELP!
Thanks in advance!

Have you tried closing all apps? Double tab the Home button, then tap down on an icon and hold for about 3 seconds, until the icons are moving slightly. Click on the above every App.

If the crash persists, then reapply the 10.4.8 combined update, again "repairing permssions" after the install/restart (I'm assuming you are using a PPC system, if you have an Intel Machine, use this combined update.
